If you've been buying sugar free candies, you're sure to have seen Hydrogenated starch hydrolysates on the ingredient lists. This corn product has 0g of sugar!
We first saw these in CVS's sugar free gummy bears, which are very tasty by the way :) Research on hydrogenated starch hydrolysates has been going on since the 1960s, and were first done in Sweden.
Also known as HSH, this compound is sweet, has bulk, and is great for candies or sweets that need a good consistency. Because there is no real sugar in this mix, they do not create cavities either.
Note that while hydrogenating OILS causes trans fats which are unhealthy, in this case you are hydrogenating a STARCH. This has not been found to be unhealthy in any way.
