Mangosteen is a kind of cucurbitane-type triterpenoid saponin, which is easily soluble in water and has a sweetness of about 300 times that of sucrose. Because of its high sweetness and low dosage, the caloric contribution to food is almost negligible.
Mangosteen extract is also rich in amino acids, fructose, vitamins and minerals. As a general natural sweetener, Mangosteen extract is an ideal substitute for synthetic sweeteners such as aspartame and high-calorie sweeteners such as sucrose. Mangosteen extract has strong thermal stability and acid-base stability. Cooking or baking does not affect its flavor or sweetness. It has broad application prospects in baked foods, nutritious foods and low-calorie foods.
