First of all ... thanks a lot for all these informative posts.
I have a question about determining the amounts of the added sugars ... especially for glucose syrup, invert sugar and sorbitol.
Is there any approximate guidelines about the ratios of these different sugar types which should be added to the recipe?
Wybauw example in the "Gold" book goes something like this ... let's add 50 gr glucose syrup and look at the aW value and then let's add 50 gr invert sugar as well and look at the aW one more time ... and finally let's add 50 gr sorbitol and look at the value of aW again.
As far as I can see from the book, there is no clue why, where and in what ratios these different types of sugar should be used.
Is there any source, rules or formulas for being able to say that ... for example ... hmmm I need to add 43 gr of glucose syrup, 37 gr invert sugar and 7 gr of sorbitol for this recipe.
Thanks a lot.
