Neotame is a high-potency synthetic non-nutritive sweetener derived from aspartame, first developed in the 1980s by French research teams and later approved for food use in dozens of countries around the world. It features extremely high sweetness intensity, ranging from 7000 to 13000 times sweeter than regular sucrose, around 30 to 60 times higher than aspartame, so only a tiny dosage is required to reach target sweetness in finished goods.

It owns pure and natural sweet flavor close to cane sugar, with no bitter or metallic aftertaste that troubles many common artificial sweeteners, and it also has prominent flavor-improving capacity to cover bitter taste from raw materials like caffeine and herbal extracts in food and medicines. Compared with aspartame, neotame gains better stability under high temperature and varied acid-base conditions, which makes it adaptable for high-temperature baking, acidic drinks and long-term stored food items.

Virtually no available calories can be absorbed by human body after intake, which means it is zero-calorie in practical application. It will not cause blood sugar fluctuation or dental caries, hence fit for diabetics, people controlling body weight and groups limiting sugar intake. It can be applied separately or compounded with other sweeteners such as sucralose and acesulfame potassium to optimize sweet taste and cut production cost for manufacturers.
