Hydrogenated starch hydrolysates (HSHs), also known as polyglycitol syrup, are mixtures of several sugar alcohols. Hydrogenated starch hydrolysates were developed by the Swedish company Lyckeby Starch in the 1960s. The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia. HSH sweeteners provide 40 to 90% sweetness relative to table sugar.
