Brief Introduction
L-Cysteine is a kind of nonessential amino acid, which exists in keratin. Keratin is the main protein of nails, toenails, skin and hair. The relationship between L-cysteine and cystine is very close. Two molecules of L-cysteine form one molecule of cystine. L-Cysteine is more unstable. It is easy to become cystine which can also be reduced to L-cysteine. Both of them are sulfur-containing amino acids, which have effects on skin formation and detoxification. L-Cysteine is mainly used in cosmetics, medicine and food. In cosmetics, it is used to prepare perm, sunscreen, hair perfume and hair essence. In the field of medicine, it is used to prepare methyl cysteine, ethyl cysteine, acetylcysteine, methyl cysteine, ethyl cysteine and comprehensive amino acid preparations. L-Cysteine can also be used as a protective drug against radiation injury. In food, L-cysteine is used as bread fermentation auxiliary (ripening agent), antioxidant stabilizer for milk powder and fruit juice, and nutrient for pet animal food.

Brief Introduction
Acesulfame is the fourth generation of synthetic sweetener. It has a certain bitter taste when used alone, and has synergistic effect when mixed with aspartame or cyclamate, and can cover up the bitter taste. After being taken to the human body, it is not absorbed and does not generate heat. It is suitable for people with diabetes and obesity. In China, it can be used for pastry, jam (excluding canned), pickles, candy, preserves, drinks, ice cream and gummy sugar, with the maximum dosage of 0.3g/kg; It can also be used as table sweetener (flake or powder), 40mg per tablet or packet.
