Sucralose Refractometer Testing ;-)

[COLOR=black]In anticipation of receiving a Sucralose Refractometer in the near future, I am interested in obtaining samples of various Liquid Sucralose solutions for testing. [/COLOR]

[COLOR=black]So far I have Quick Sweet Liquid Sucralose on hand and EZ-Sweetz on order. [/COLOR]

[COLOR=black]I am asking that those of you who have the original Tate & Lyle Liquid Sucralose, Sweetzfree, Trish’s Liquid Sucralose and or any other versions of Liquid Sucralose you may wish tested consider contacting me by PM (private message) to arrange sending a small sample of these products to me for testing. I expect that ~1 teaspoonful in 2 ziplock baggies (double bagged) in a padded USPS envelope will suffice…[/COLOR]

[COLOR=black]I’m really hoping that we will be able to determine a more definitive value for these concentrations for more accurate comparison of their relative strengths (without having to rely upon approximations currently so prevalent ;-)[/COLOR]

[COLOR=black]I plan to publish the test results, as they are made in this thread…[/COLOR]

[COLOR=black]Thanks in advance for your assistance and/or comments![/COLOR]

I bought some concentrate in 2005 from a guy in Australia - I'm still using it - would that be of any benefit to what you're doing? If so I'm happy to send a smidge to you!

LOL! Yes! I'll be happy to test it for you...at least YOU will 'know' its strength. If it has a product name, perhaps others may have purchased it as well. I plan to test all of my own concoctions and am especially interested in finding the actual strength of the Commercial Products now on the market...

Just PM your email addy and I'll send you my mailing address...

What fun ;-)

Charski, is that liquid splenda from someone named Dale? I bought some from Australia about the same time that I am still using also, so I will be interested in knowing your test results if lowcarbman posts them here.

Charski, I found your source, Dale Hoffman-Australia, and the following email information, dated March 1, 2004.

Yes, you are able to purchase it from me. Cost for the syrup is US$28 all inclusive for 7oz bottle. Measurement is 2 tsp = 1 cup sugar. Each bottle contains 20 cups of equiv.
You can also purchase pure splenda for US$54 for 6oz bottle. Equiv to 170 cups of sugar.
Please pay via paypal to my email address if you are interested.
Cheers
Dale”

This makes your product a strength of 24 times sugar (48t sugar / 2t product)…will confirm this strength for you on the refractometer when it arrives… ;-)

PS: Ordered Fiberfit and Sweetzfree yesterday to test them as well... ;-)

Just to clarify, cuz math is NOT my strong point, that what I bought from Dale is the "pure splenda" not the syrup. It is liquid so we KNOW it ain't PURE as in the powdered pure kind but I'll be interested to see if your measurement of it gives the "170 cups of sugar" equivalence that he claims!

I make it up with boiled water in small amounts and per his instructions for dilution and I find it just dandy!

Sucralose/Spenda Digital Refractometer Info

If you haven't purchased your refractometer yet, i'd check out MISCO (Cleve, OH). MISCO has developed a direct reading digital refractometer capable of reading both pure Sucralose solutions, and for solutions containing the SPLENDA®-brand consumer sweetener. Michael Rainer is very helpful in explaining his company's instrument, 800-358-1100.

Another Dale customer--

I, too, have purchased the pure splenda that he offers. Twice, in fact. I will also be interested in the results of Charski's sample.
Thanks, Locarbman. So good to see you back with us.

Thank you for the contact info Michael, I have a download of your Press release February 27 2005 ;-) My order for the Sucralose/Splenda Palm Abbe was placed recently...

[COLOR=#22229c]MISCO Palm Abbe Digital Refractometer for Sucralose and Splenda[/COLOR]

http://www.misco.com/images/MISCO_Palm_Abbe.pdf

Kathy Widing called to advise that shipment of the Palm Abbe Sucralose/Splenda Refractometer would take place around "the last week in January". Am looking forward to its receipt...will make preparation of my personal liquid Sucralose potions more accurate ;-)

Will definitely call upon receipt!

Hi helper ;-)

Good to see you too! Here is an update on my Liquid Sucralose calculations...hope it's not too confusing...lol!

[COLOR=#22229c][COLOR=#000000]Strength Calculator ;-)[/COLOR]

[COLOR=#000000]It is difficult to transfer a spreadsheet (with automatic calculations) to a word document for posting…but here goes… ;-)[/COLOR]

[COLOR=#000000]This chart indicates my current assessment of the Liquid Sucralose solutions I plan to test:[/COLOR]

[COLOR=#000000]....................Grams....Milliliters...Strengt h...Grams...Teaspoons...Cups>100ml...Cups>Cup [/COLOR]
[COLOR=#000000]Product.......Sucralose...Water.....Sucralose...Su gar......Sugar...........Sugar..........<<Ratio[/COLOR]
[COLOR=#000000]25w/v.............25..........100............600.......15000......3750............78.13..............185 [/COLOR]
[COLOR=#000000]QuickSweet......25..........100............600.......15000.......3750.............78.13......... ......185[/COLOR]
[COLOR=#000000]Sweetzfree......27........[/COLOR][COLOR=#000000]...100............600.......16230.......4057.............84.53......... .....200[/COLOR]

[COLOR=#000000]LiquidSplenda...27...........100.............600.......16230.......4057.............84.53......... ......200[/COLOR]

[COLOR=#000000]NOTES:[/COLOR]
[COLOR=#000000]1 – 25%w/v values are all correct, by definition, for preperation of a weight / volume solution.[/COLOR]
[COLOR=#000000]2 – Quick Sweet values should be correct per the claim “25% by weight” preparation.[/COLOR]
[COLOR=#000000]3 – Sweetzfree values should be correct per the claim “1 cup of suger per ¼ teaspoon solution”.[/COLOR]
[COLOR=#000000]4 – EZ-Sweet values should be correct per the claim “0.5oz container = 300 teaspoons sugar”.[/COLOR]
[COLOR=#000000]5 – Fiberfit values should be correct per the claim “1 teaspoon = 8 teaspoons sugar”.[/COLOR]
[COLOR=#000000]6 – Dale-Australia values should be correct per the claim “6oz = 170 cups sugar”.[/COLOR]
[COLOR=#000000]7 – Liquid Splenda (Tate & Lyle) should be correct per the claim “1 cup sugar per ¼ t solution”.[/COLOR]
[COLOR=#000000]8 – Highlighted values are known established values or claimed values used to extrapolate other values.[/COLOR]
[COLOR=#000000]9 – Equations:[/COLOR]
[COLOR=#000000]Grams Sugar = Grams Sucralose times Strength Sucralose.[/COLOR]
[COLOR=#000000]Teaspoons Sugar = Grams Sugar times 0.25 teaspoon per gram sugar.[/COLOR]
[COLOR=#000000]Cups>100ml Sugar = teaspoons sugar divided by 48 (teaspoons per cup sugar).[/COLOR]
[COLOR=#000000]Cups>Cup = Ratio of cups per 100ml to X (unknown) cups per 236.6ml (1 cup).[/COLOR]
[COLOR=#000000]Example - 78.125c is to 100ml as Xc is to 236.6ml; X=78.125*236.6/100; X= 184.5[/COLOR]

[COLOR=#000000]I currently have samples for these solutions either on hand or on order, except for the original Liquid Splenda (Tate & lyle or McNeil, any contributor out there? ;-) and plan to use the Sucralose Refractometer to confirm (or reject ;-) these values…in the interest of truth and accuracy…of course… ;-)[/COLOR]

[COLOR=#000000]Cheers[/COLOR]

Lowcarbman, the Splenda I got from Dale-Australia was received in liquid form. I didn't convert it from powder. The claim is 1 ml (¼tsp) = 1 cup. Is this the same as the sample you are testing from him?

Hi Judy,

Yes, Charski is sending me a sample of the liquid form in the mail...haven't received it yet. The chart above is comprised of 'expected' values based upon information/claims I have now for each product. I can then compare these 'expected' values to the 'actual' results of future tests.

If you refer to the chart above, you will see that Dale's Liquid Sucralose has 100 cups sugar equivalence per 100 milliliters of product...therefore it has 1 cup sugar equivalence per each 1 milliliter (1/4 teaspoon) of product. The chart values to the right of each product name are all based upon a 100ml volume of the liquid Sucralose form. Also, my calculations for Dale's product are based upon [UK] conversion values, applicable in Australia...oops, I'll have to recheck the 'Teaspoons Sugar' values for Dale's product, looks like [US] conversion values may have crept in...should be 6720 Teaspoons Sugar, conversion factor is .25 [US] and .35 [UK];-)

PS: The 'Cups>Cup' column is the 'Strength' of the product (ie: a strength of 200 means that 1 measure of the product is equal to 200 equivalent measures of sugar)...was unable to add this to the chart above...this posting format gets a bit fussy sometimes...lol!

The 25% w/v Sucralose powder solution ;-)

Hi again,

Thought a copy of my post from the 'Make your own liquid Splenda!' thread might make the above chart a bit more understandable... ;-)

"The purpose of this post is to share my efforts to define an ‘accurate’ strength reference for a 25% weight / volume solution of Sucralose powder…now that it has become commercially available. ;-)

The basic question is just how much sugar equivalence is contained in a given volume of a 25% w/v Sucralose powder solution? And, how should it be expressed as the ‘strength’ of this solution?

“Strength”, per Webster's Online Dictionary, “is a term applied to the quantity of active substance per unit volume of a solution.”

We know that a 25% w/v solution requires 25 grams solute (Sucralose Powder) per 100 milliliters liquid (water).

We also know that Sucralose powder has a strength of 600 times sugar (literature consensus).

Therefore 25 grams Sucralose powder will equal 15,000 grams of sugar equivalence (25g*600g, weight to weight).

From the Online Conversion site

[COLOR=#800080]http://www.onlineconversion.com/weight_volume_cooking.htm[/COLOR]

granulated sugar - 1 gram = 0.250474242236 teaspoon [US]

granulated sugar - 1 gram = 0.347605725707 teaspoon [UK]

Multiplying 15,000 grams sugar equivalency by 0.25 grams per teaspoon [US] equals 3,750 teaspoons (weight to volume) of sugar equivalence per 100 milliliters of solution.

Further, dividing 3,750 teaspoon sugar equivalence by 48 teaspoons per cup equals 78.125 cups (7 1/8th cup ;-) of sugar equivalence per 100 milliliters of solution.

To find the 'strength' of 1 cup of solution, we use a ratio:

78.125 cups sugar equivalence is to 100 milliliters solution as X(unknown) cups sugar equivalence is to 236.6 milliliters (1 cup) solution. X=78.125*236.6/100; X=185 cups sugar equivalence per 1 cup of 25% weight / volume solution of Sucralose powder.

Tof find the value in grams to make 1 cup of solution, we use a ratio:

25 grams Sucralose is to 100 milliliters solution as X(unknown) grams Sucralose is to 236.6 milliliters (1 cup) solution. X= 25*236.6/100; X=59.15 grams Sucralose powder per 1 cup of 25% weight / volume solution of Sucralose powder.

Per Webster’s definition, we now have a value of 59.15 grams (185 cups sugar equivalence) of Sucralose powder (active substance) per 1 cup water (unit volume) of a solution.

I submit that a true ‘strength’ value for a 25% w/v Sucralose powder solution is 185 times sugar!!!

[COLOR=black]Given that 25%w/v Sucralose is 185 times sugar:[/COLOR]

[COLOR=black]1t. 25%w/v Sucralose = 3.85 cups sugar (185/48)(~4cups ;-)[/COLOR]
[COLOR=black]1/2t. 25%w/v Sucralose = 1.92 cups sugar (92 teaspoons)(~2cups)[/COLOR]
[COLOR=black]1/4t. 25%w/v Sucralose = 0.96 cup sugar (46 teaspoons)(~1cup)[/COLOR]
[COLOR=black]1/8t. 25%w/v Sucralose = 0.48 cup sugar (23 teaspoons)(~1/2cup)[/COLOR]
[COLOR=black]1/16t. 25%w/v Sucralose = 0.24 cup sugar (12 teaspoons)(1/4cup)[/COLOR]
[COLOR=black]1/32t. 25%w/v Sucralose = 0.12 cup sugar (6 teaspoons)(1/8cup)[/COLOR]

[COLOR=black]For those interested in the convenience of ‘accurately’ ;-) mixing a 25% w/v Sucralose powder solution, without the fuss of weighing to the nearest 100th of a gram or using approximate volume conversions, I would like to suggest that you may mix a 2 oz container (pre weighed ;-) of Quick Sweet Sucralose powder in 1 cup less 2 teaspoons water… [/COLOR]

PS: This strength applies to all 25% w/v Sucralose powder solutions regardless of the source of 'pure Sucralose powder'."

These calculations also apply to the other %w/v values in the chart above, noting that 'Dale-Australia' will use [UK] rather than [US] conversion factors...

Hope this helps...

LOL! I just placed an order with Dale Hoffman, Australia. Took a total of 15 minutes ;-)

I found an old post on another board (Google Searched) from 2004 giving his email address and tried it to see if he was still selling 6 ounce bottles of "Pure Splenda”. Much to my surprise he responded in minutes.

Yup, I still sell the pure splenda. All inclusive cost for 6oz bottle is US$64.00. I will send a Paypal invoice, in case you decide to go ahead.

Cheers
Dale”

PS: I just posted my first ever Low Carb Friends 'locarbman' BLOG (Thanks, Tom). Getting it ready as a more convenient means of posting the Refractometer test results...check it out and please comment if you have any suggestions or corrections... ;-)

Update:

Received my 'Liquid Sucralose' from Dale Hoffman yesterday, took 2 weeks from Australia...ordered 1/29, shipped 2/4, received 2/12.

Called MISCO about my order yesterday and was told (by Ann) that the Sucralose/Splenda Refractometer is scheduled for shipment Friday or Saturday.

Have 8 liquid Sucralose samples currently ready to test...you may check my Sucralose Refractometer BLOG for current 'claimed strength' results related to these samples...we'll see how they compare to a refractometer test! ;-)

Not that it matters really, but I'm pretty sure Dale is female. I've been buying from her for a long time. I hardly use it any more, and had a year old batch of diluted splenda lose its potency. She said her diluted splenda has lasted 2 years, so I don't know why mined didn't. Maybe my house gets hotter. I keep it in the refrigerator now.

Sucralose Refractometer Testing Results ;-)

Posted 01-29-2009 at 11:18 AM by [COLOR=#22229c]locarbman[/COLOR]
Updated 02-20-2009 at 03:40 PM by [COLOR=#22229c]locarbman[/COLOR]
Objective:

To determine the 'actual strength' of currently available commercial Liquid Sucralose Products and LCF member solutions (created with the now, commercially available Sucralose powder ;-) using the new MISCO Sucralose/Splenda Refractometer. Then, to compare these test results to those obtained by calculating results based upon Label and/or Website claims.

Testing Caveats:

1 - Sample solutions may evaporate over time yielding a slightly stronger strength (ie: My 2oz Quick Sweet Powdered Sucralose 25% w/v solution (several weeks old and refrigerated), and Charski’s Dale-Australia sample (although double bagged and sealed with a Food Saver, I do not know the date received by Charski… ;-)

2 - Commercial (previously unopened) solution strengths may vary within production limits (ie: Quick Sweet Liquid Sucralose, Sweetzfree, EZ-Sweetz, Fiberfit, Tasty-Free and Dale-Australia Pure Splenda).

Methodology:

1-2 drops solution to be placed on the MISCO Sucralose/Splenda Refractometer, Degree Brix readings to be recorded on (3 consecutive days).

The resulting Degree Brix readings indicate the percent of Sucralose powder by weight (grams per 100 milliliters of water). Brix is a relative density scale named after the 19th century Austrian scientist Adolf Brix.

TESTS:

1 – Quick Sweet Liquid Sucralose: (Price per 4.23floz (120g) bottle = $20)
Label - “Serving Size 3 Drops (110mg) = 2 Teaspoons of Sugar, Servings about 1100, NET WT 4.23oz (120g)”
Reference Website ( [COLOR=#800080]https://www.ahfni.com/store/sucralose.php[/COLOR] ) “[COLOR=#333333]Liquid Sucralose: [/COLOR][COLOR=#333333]water, sucralose (25% of total weight).”[/COLOR]

Label Results > Grams = 12, Milliliters = 100, Strength = 86 times sugar

Website Results > Grams = 25, Milliliters = 100, Strength = 185 times sugar

2/20/2009 (Freshly opened bottle)

Test Results > Grams = 25.8, Milliliters = 100, Strength = 191 times sugar

Price per 1 cup Sugar Equivilance = $0.20

2 – Sweetzfree: (Price per 1floz bottle = $18.00)
Label - “¼ teaspoon (25 drops) = 1 cup sugar; 1 drop = 1 rounded teaspoon sugar, 1 ounce = 24 cups sugar
Reference Website ( [COLOR=#800080]www.sweetzfree.com[/COLOR] ) "1 Ounce, the equivalent of 24 cups of sugar"
From my recent order (1/24/2009) fact sheet " I will be happy to respond to all requests or comments. Diane [COLOR=#22229c]sales@sweetzfree.com[/COLOR] "

Label Results > Grams = 26, Milliliters = 100, Strength = 192 times sugar

'Drops' are not a sufficiently accurate physical volume measure to use in calculating strength, however, equating drops to serving size and serving size to a volume measure (24 drops/servings sweetness to 1 cup of sugar) yields the following label results...

Label Results > Grams = 41, Milliliters = 100, Strength = 300 times sugar

Website #1 Results > Grams = 41, Milliliters = 100, Strength = 300 times sugar

2/20/2009 (Freshly opened bottle)

Test Results > Grams = 25, Milliliters = 100, Strength = 185 times sugar

Price per 1 cup Sugar Equivilance = $0.61

4 – Fiberfit: (Price per 4floz bottle = $5.29)
Label - "1 teaspoon provides 1 gram of soluble fiber and has the sweetness of approximately 8 teaspoons of sugar."

9 - Locarbman's Old Standby (1/2oz Sucralose powder per 1 cup water):
Label - (no label, homemade ;-)
Reference Website - N/A

2/20/2009 (Prepared ~3 months ago, Refrigerated)

Test Results > Grams = 9.7, Milliliters = 100, Strength = 72 times sugar (1.5 cups sugar equivalence per teaspoon, I finally know the real strength of this solution...lol)

DEFINITIONS (Results):

Grams = the number of grams Sucralose powder per 100 milliliters of the sample solution.

Milliliters = the volume of liquid used in a % gram weight/volume solution.

Strength = the volume measure of solution to the same volume measure of sugar equivalence (ie: a strength of 185 means 1 teaspoon of solution is equal to 185 teaspoons sugar equivalence).

[COLOR=black]Sample calculations:[/COLOR]

[COLOR=black]Given Strength (ie: a liquid Sucralose solution at a strength of 185 times sugar):[/COLOR]

[COLOR=black]1 – Determine Cups of sugar equivalence per 100ml of solution.[/COLOR][COLOR=black] A strength of 185 means there are 185 cups of sugar equivalence in 236.6ml (1 cup) solution. Use a ratio: 185c is to 236.6ml as Xc is to 100ml; Xc=185*100/236.6; Xc=78.19 cups of sugar equivalence per 100ml of solution.[/COLOR]
[COLOR=black]2 – Determine Teaspoons sugar equivalence per 100ml of solution.[/COLOR][COLOR=black] Multiply Cups per 100ml by 48t/cup. 78.19c*48t/c=3753 teaspoons of sugar equivalence per 100ml of solution.[/COLOR]
[COLOR=black]3 – Determine gram weight of sugar equivalence per 100ml of solution.[/COLOR][COLOR=black] Divide teaspoons of sugar equivalence by .25 grams per teaspoon granulated sugar. 3753tseq/.25g/tgransug = 15013 grams granulated sugar equivalence per 100ml of solution.[/COLOR]
[COLOR=black]4 – Determine grams of sucralose powder to mix in 100ml water for a 185 strength solution.[/COLOR][COLOR=black] Divide grams sugar by 600 (strength of sucralose powder). 15013gsugar/600=25grams Sucralose powder to mix in 100ml water for a 185 strength solution.[/COLOR]

[COLOR=black]Given Volume to Sugar Relationship (ie: 1 fluid ounce = 24 cups sugar):[/COLOR]

[COLOR=black]1 – Determine cups of suger equivalence per 100 milliliter of solution.[/COLOR][COLOR=black] Per the volume conversion chart, 1floz=29.57ml. Use a ratio: 24c is to 29.57ml as Xc is to 100ml; Xc=24*100/29.57; Xc=81 cups of sugar equivalence per 100 milliliter of solution.[/COLOR]
[COLOR=black]2 – Determine Teaspoons sugar equivalence per 100ml of solution.[/COLOR][COLOR=black] Multiply Cups per 100ml by 48t/cup. 81c*48t/c=3888 teaspoons of sugar equivalence per 100ml of solution.[/COLOR]
[COLOR=black]3 – Determine gram weight of sugar equivalence per 100ml of solution.[/COLOR][COLOR=black] Divide teaspoons of sugar equivalence by .25 grams per teaspoon granulated sugar. 3888tseq/.25g/tgransug = 15552 grams granulated sugar equivalence per 100ml of solution.[/COLOR]
[COLOR=black]4 – Determine grams of sucralose powder mixed in 100ml water.[/COLOR][COLOR=black] Divide grams sugar by 600 (strength of sucralose powder). 15552gsugar/600=26grams Sucralose powder mixed in 100ml water.[/COLOR]
[COLOR=black]5 – Determine Strength of this solution.[/COLOR][COLOR=black] Use a ratio 81c is to 100ml as Xc is to 236.6ml; Xc=81*236.6/100; Xc=192 cups sugar equivalence per 1 cup solution for a Strength of 192 times sugar.[/COLOR]

Calculation Aids:

Now that we have 'scientifically tested' strengths for the above solutions…any questions? ;-)

PS: Anyone interested in a 'slightly' used Splenda/Sucralose Refractometer for ~$435? LOL!

Me, Too!

I need to buy some more sooner rather than later. What is your opinion as to the best value for the money?

[COLOR=black]LOL! There are many subjective reasons for a purchase, convenience, volume, cost or just personal preferance…I’m trying my best to be objective… ;-) [/COLOR]

[COLOR=black]First, let me say that EZ-Sweetz is available in a convenient, purse sized bottle with built in dropper at Netrition.com (let’s support our Low Carb Friends sponsor). [/COLOR]

[COLOR=black]Second, there is the consideration of how quickly you use your liquid Sucralose…the less frequently you have to order, the less shipping/handling costs you will have. [/COLOR]

[COLOR=black]Last, it would appear that the Quick Sweet products (liquid and powder) will give you the most ‘Bang’ for the ‘Buck’ ;-)[/COLOR]

All of the products tested above consist of Water, pure Sucralose powder and preservatives except for those solutions I have made from just water and Sucralose powder (my personal preferance ;-)

I have felt like a kid in a candy store working on this project and am very happy that Sucralose and Stevia powders are now approved and commercially available!!!

[COLOR=black]Hope this helps![/COLOR]

Awwww Shucks, (looking down and digging right toe in the dirt...thanks... ;-)

As a resut of the above testing, I am developing some questions for a call to the MISCO experts...

[COLOR=black]MISCO Questions:[/COLOR]

[COLOR=black]1- [/COLOR][COLOR=black]My Tasty-Free sample, repeatedly gives “sample out of range +”. Given the Sucralose scale range of 0 to 80 grams and the 1.25oz bottle listing ingredients as “contents purified water, 100% pure sucralose, 1.25oz = 30 cups sugar” yielding a calculated strength of 26g per 100ml, and other 26g per 100ml products test properly, what could cause this reading???[/COLOR]
[COLOR=black]2- [/COLOR][COLOR=black]Is there an upper limit for a Sucralose concentration? (where the 100ml water will no longer dissolve additional Sucralose powder ie: a limit of 26g or 25% by weight solution) Perhaps a lower strength solution that has evaporated some of its[/COLOR][COLOR=black] water may give higher concentrations or will the solute begin dropping out of solution? If so, what would be the possible upper strength limit?[/COLOR]
[COLOR=black]3- [/COLOR][COLOR=black]As the FDA has now approved Stevia as GRAS for use as a sweetener in foods, would you consider a scale for testing liquid Stevia solutions?[/COLOR]
4-???

Are there any questions you would like added to my list?

Can the Sucralose Refractometer tell us how much sucralose is in sugar-free drinks? I am guessing something like Fruit2O and other flavored waters contain less sucralose than something like a Diet Coke with Splenda.

[COLOR=black]Good question! I’ll add it to my list when I call MISCO. I will try the refractometer on a can of Diet Rite pure zero Cola sweetened with Sucralose (Splenda) that I have on hand (when it warms up) to see what reading I get… ;-) I Looked for Fruit20 but our local groceries aren’t carrying it. Did find some flavored waters though, AquaFina brand with Splenda, will pick up a 6 pack tomorrow (the Western Family flavored waters are sweetened with Ace-K). My Diet Coke is sweetened with Aspartame ;-( will have to check tomorrow for the Splenda sweetened product…[/COLOR]

[COLOR=black]I have been able to add Sucralose powder to my old 9.7 gram solution (1/2oz Sucralose in 1 cup water) bringing it up to a 26 gram w/v solution which has a strength of 192 times sugar (where ¼ teaspoon equals 1 cup of sugar equivalence… ;-) I find that the solution needs to be shaken occasionally and allowed to sit (unrefrigerated) overnight to get all of the added Sucralose powder into solution.[/COLOR]

[COLOR=black]I have also ordered a graduated 200ml beaker for mixing future Sucralose solutions. My measuring cup indicates 250ml per 1 cup, not the actual 236.6ml per cup given on the Volume Conversion site…oh well, the cup makers were close…lol![/COLOR]

PS: The refractometer has separate scales for Sucralose and for Splenda...will ask MISCO for information regarding the basis for this distinction...

Update:

[COLOR=black]2/26/2009[/COLOR][COLOR=black] 6:30am I just talked to John (1-800-358-1100 (ext. 211)) at MISCO. He was easy to talk to and a wealth of infomation, spent about 15 minutes discussing the Palm Abbe 202 Splenda/Sucralose Refractometer and its use with Sucralose and Splenda scales.[/COLOR]

  • The Sucralose scale range is actually 0 to 30 percent by weight. The Splenda scale range is 0 to 40 percent by weight. These scales replace the Brix Refractive Index scale (0-85.0 Brix) mentioned in the MISCO Instruction Manual.
  • The above scales relate to grams of Sucralose or grams of Splenda in a water solution only. They will NOT determine Sucralose or Splenda concentrations in complex (multi ingredient) solutions (ie: Fiberfit, flavored waters or soft drinks containing Sucralose). The Sucralose scale is based upon the single substance pure Sucralose in distilled water. The Splenda scale is based upon the Tate & Lyle commercial mixture of Sucralose and Maltodextrin in distilled water.
  • MISCO will prepare a scale for Liquid Stevia, if I submit the appropriate data, and will replace my Splenda scale with the Stevia scale if and when I desire. This scale would only be valid for the substance I use (Now Brand Stevia Extract ;-) in water and would not be suitable for comparison with other Stevia Extract products (ie Truvia, NuNaturals, etc)...
  • Sucralose has a maximum achievable concentration level of 28 grams per 100 millilliters of water.
  • John recommends I try diluting the Tasty-Free sample with distilled water to determine a reading on the refractometer and proceed from that point, he is unable to explain why it consistently reads “Sample Out of Range+” at this time…
[COLOR=black]PS: I added an additional ½ teaspoon Sucralose powder to my 26g w/v solution yesterday and the reading today is still 26g with the added powder sitting at the bottom of the container…guess this is the strongest solution I can make with my powder/method…but it works for me... ;-)[/COLOR]

Update:

2/27/2009 1pm: I just talked to John, requesting the MISCO lab email me instructions for developing a Palm Abbe scale for Stevia (and any other products we may wish to pursue). He suggests they may need to replace the Splenda scale on my refractometer with a Brix scale to enable me to produce the necessary readings for a Stevia scale...will keep you advised... ;-)
