They were asked to use it as a one-for-one replacement for table sugar and were urged to bake with it. Suggested uses were in cakes, cookies, pies, hard candy, hot and cold cereals, cold fruit drinks, iced tea, coffee and tea. The consumers were asked to fill out a questionnaire about the product at the end of the evaluation period. Twenty-four completed questionnaires were returned and tabulated.

"Turned yellow/brown when I put [it] on top of sugar cookies & baked them."
*Note from Management: Two of the sugars in Whey Low® are known to brown easily in baking. The fruit and milk sugars form trace amounts of Maillard products with flour more easily than does ordinary sugar. These Maillard products are the normal colored and fragrant products found in most baked goods. The way to minimize browning is to limit the exposure time to oven temperatures. In this particular case, the Whey Low® should be sprinkled on the cookies immediately after the cookies are removed from the oven.
"Noticed slight [dairy] odor of product in container"
*Note from Management: We have changed supplier of the offending ingredient. The odor is gone, and the color is also improved.

Any aspects of its use in foods that displeased you?
2 Yes 22 No
"Molasses cookies too soft, but tasted great."
"Sugar cookies were not crisp."
"I couldn't see any difference [from table sugar] in the cookies I baked or the use in my cereal..."

Any personally negative aspects?
(all answers written into questionnaire by consumer, w/o any suggesting or prodding)
22 reported "none."
1 reported, "It is cariogenic, like sucrose."
*Note from Management: We do expect the sweetener to be nearly as cariogenic (i.e. causing tooth decay) as table sugar. With the broad consumption of fluoridated water in public water systems and improvements in oral health care, tooth decay is not nearly the problem it was in the 50's and 60's in the US.
1 reported, "Baked goods brown faster - bars, cakes, etc."
* Note from Management: When baking with Whey Low® Granular, always use the minimum oven time recommended in the recipe.
