To determine the 'actual strength' of currently available commercial Liquid Sucralose Products and member solutions (created with the now, commercially available Sucralose powder ;-) using the new MISCO Splenda/Sucralose 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).
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 Splenda/Sucralose Refractometer, Sucralose scale readings to be recorded on (3 consecutive days).
The resulting Sucralose scale readings indicate the percent of Sucralose powder by weight (grams per 100 milliliters of water).
TESTS:
1 – Quick Sweet Liquid Sucralose: (Price per 4.23floz (125ml, 120g) bottle = $20) Ingredients: Water, sucralose (25% of total weight), citric acid, sodium citrate, with potassium sorbate and sodium benzoate as preservatives. Label: “Serving Size 3 Drops(110mg) = 2 Teaspoons of Sugar, Servings about 1100, NET WT 4.23oz (125ml, 120g)” Reference Website: ( https://www.ahfni.com/store/sucralose.php ) “Liquid Sucralose: water, sucralose (25% of total weight).”
Test Results: Grams = 25.8, Milliliters = 100, Strength = 190.759 times sugar
Price per 1 cup Sugar Equivalence = $0.20
2 – Sweetzfree: (Price per 1floz (30ml) bottle = $18.00) Ingredients: Purified water, 100% pure Sucralose Label: “ΒΌ teaspoon (25 drops) = 1 cup sugar; 1 drop = 1 rounded teaspoon sugar, 1 ounce = 24 cups sugar” Reference Website: ( www.sweetzfree.com ) "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 sales@sweetzfree.com "
Test Results: Grams = 24.7, Milliliters = 100, Strength = 182.626 times sugar
Price per 1 cup Sugar Equivalence = $0.79
3 – EZ-Sweetz: (Price per 0.5floz (15ml) bottle = $6.99) Ingredients: Filtered Water, Sucralose, Potassium Sorbate, Sodium Benzoate, Succinic Acid, and Citric Acid. Label: “One Drop = 1 Serving, One Bottle ~450 Servings, 0.5floz (15ml), Serving Size: 1 drop (as sweet as 2 tsp of sugar) 24 drops is as sweet as 1 cup of sugar Servings per Container = 450” Reference Website #1: ( http://www.netrition.com/ezsweetz.html ) “a small .5oz container can serve 450 servings, that is 900 teaspoons or 5.9lb of sugar!.” Reference Website #2: ( http://www.ez-sweetz.com ) No indication of strength compared to sugar!
NOTE: '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...
Test Results: Grams = 25, Milliliters = 100, Strength = 184.844 times sugar
Price per 1 cup Sugar Equivalence = $0.61
4 – Fiberfit: (Price per 4floz (118ml) bottle = $5.29) Ingredients: Purified water, soluble fiber, sucralose, gluconic acid, guar gum, Irish moss, Preserved with less than1/10th of 1% potassium sorbateand sodium benzoate. Label: "1 teaspoon provides 1 gram of soluble fiber and has the sweetness of approximately 8 teaspoons of sugar." Reference Website #1: ( http://www.netrition.com/nutragenics_fiberfit_page.html ) "Each teaspoon of Fiberfit has the sweetness of approximately 8 teaspoons of sugar" Reference Website #2: ( www.fiberfit.net/ ) "Each teaspoon of Fiberfit has the sweetness of approximately 8 teaspoons of sugar"
Test Results: Grams = 21.5, Milliliters = 100, Strength = 158.966 times sugar
***False Results*** (not a Sucralose only solution? Due to added fiber?)
2/26/2009 Confirmed by John, MISCO. The refractometer scale readings apply to Sucralose/Water concentrations only! This (21.5g) reading does, however, have value for those creating an equivalent, homemade version of this Sucralose, Fiber solution. Merely add 1 gram Sucralose powder to 100ml water and a fiber product (such as Clearly Fiber) until you read 21.5 on the refractometer ;-)
Price per 1 cup Sugar Equivalence = $1.32
5 – Charski’s Dale-Australia 'Pure Splenda’: (Price per 6oz bottle = ?) Ingredients:Water, sucralose, citric acid, sodium citrate, preservatives (potassium sorbate, sodium benzoate). Label #1: Per Charski "6oz bottle = 170 cups sugar" Label #2: Per judytab "1ml = 1 cup sugar" Reference Website: http://www.passthetoast.com/ was the web site (no longer active). Email - dalehoffman@optusnet.com.au was the e-mail address for the Australian source (still active).
***Sample Out of Range +*** (Scale range 0 to 80 grams per 100ml) ???
Price per 1 cup Sugar Equivalence = ?
2/26/2009 Suggested by John, MISCO. Try diluting a measured amount with drops of distilled water until a reading is obtained on the refractometer and proceed from there...
8 – Locarbman's ‘Quick Sweet Sucralose powder 25% w/v solution’ (2oz container Quick Sweet Sucralose powder in 1 cup less 2t water): (Price per 2oz Sucralose powder = $38 Ingredients: Tap water, pure Sucralose. Label: (no label, homemade ;-) Reference Website: ( https://www.ahfni.com/store/sucralose.php )"Quick Sweet Powder 1oz. = 35 lb. of Sugar, NET WT 2oz (56.7g), Serving Size 20mg, Servings per Container: about 2840 Zero Calories • 600 times as sweet as sugar • Safe for cooking"
Test Results: Grams = 25, Milliliters = 100, Strength = 184.844 times sugar
Price per 1 cup Sugar Equivalence = $0.21
9 - Locarbman's Old Standby (1/2oz Sucralose powder per 1 cup water): (purchased ~20oz from Best Body Products 2002-03 (no longer available) for $28 per ounce ;-) Ingredients: Tap water, pure sucralose powder. Label: (no label, homemade ;-) Reference Website: N/A
2/20/2009 (Prepared ~3 months ago, Refrigerated)
Test Results: Grams = 9.7, Milliliters = 100, Strength = 71.719 times sugar (1.5 cups sugar equivalence per teaspoon, I finally know the real strength of this solution...lol)
Price for 1 cup Sugar Equivalence = $0.39
NOTE: I combined the above two locarbman solutions (370ml) and added Sucralose powder to achieve the maximum strength possible. It was 26 grams per 100ml water when excess Sucralose powder no longer went into solution...
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).
Sample calculations:
Given Strength (ie: a liquid Sucralose solution at a strength of 185 times sugar):
1 – Determine Cups of sugar equivalence per 100ml of solution. 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.
2 – Determine Teaspoons sugar equivalence per 100ml of solution. Multiply Cups per 100ml by 48t/cup. 78.19c*48t/c=3753 teaspoons of sugar equivalence per 100ml of solution.
3 – Determine gram weight of sugar equivalence per 100ml of solution. Divide teaspoons of sugar equivalence by .25 grams per teaspoon granulated sugar. 3753tseq/.25g/tgransug = 15013 grams granulated sugar equivalence per 100ml of solution.
4 – Determine grams of sucralose powder to mix in 100ml water for a 185 strength solution. Divide grams sugar by 600 (strength of sucralose powder). 15013gsugar/600=25grams Sucralose powder to mix in 100ml water for a 185 strength solution.
Given Volume to Sugar Relationship (ie: 1 fluid ounce = 24 cups sugar):
1 – Determine cups of suger equivalence per 100 milliliter of solution.
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.
2 – Determine Teaspoons sugar equivalence per 100ml of solution.
Multiply Cups per 100ml by 48t/cup. 81c*48t/c=3888 teaspoons of sugar equivalence per 100ml of solution.
3 – Determine gram weight of sugar equivalence per 100ml of solution.
Divide teaspoons of sugar equivalence by .25 grams per teaspoon granulated sugar. 3888tseq/.25g/tgransug = 15552 grams granulated sugar equivalence per 100ml of solution.
4 – Determine grams of sucralose powder mixed in 100ml water.
Divide grams sugar by 600 (strength of sucralose powder). 15552gsugar/600=26grams Sucralose powder mixed in 100ml water.
5 – Determine Strength of this solution.
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.
