White crystalline powder in appearance, organic synthetic salt, similar in taste to sugarcane, soluble in water and slightly soluble in alcohol. Acesulfame K has stable chemical properties and is not easy to decompose and fail. Does not participate in body metabolism, does not provide energy; High sweetness and low price; No dental caries; It has good stability to heat and acid, and is the fourth generation synthetic sweetener in the world.

2. Sodium alginate

White or light yellow powder, almost odorless. Sodium alginate is soluble in water and insoluble in organic solvents such as ethanol, ether and chloroform. Dissolve in water to form viscous liquid, and the pH value of 1% aqueous solution is 6-8. When pH=6-9, the viscosity is stable, and when heated above 80℃, the viscosity decreases. Sodium alginate is nontoxic, LD50 >: 5000 mg/kg.

3, vitamin Eα tocopherol:

Vitamin E is a fat-soluble vitamin with eight forms and is an important antioxidant. Vitamin E includes two ***8 compounds, namely α, β, γ, δ tocopherol and α, β, γ, δ tocopherol. α -tocopherol is the most widely distributed, abundant and active vitamin E in nature.

4, vitamin C ascorbic acid:

Vitamin C has the structure of alkylene glycol. Due to the * * yoke effect, the acidity of C2-OH is very weak (pK2= 1 1.57) and C3-OH is very strong (pK 1=4. 17), so vitamins generally behave as monobasic acids.

5. Aspartame (including phenylalanine):

At a certain temperature and acidic pH value, the ester bond of aspartame aqueous solution can be hydrolyzed into aspartyl phenylalanine and methanol. In neutral, alkaline (pH >；; 7) Under the condition of heating or cyclization, methanol is eliminated to form cyclic aspartyl phenylalanine. Finally, aspartyl phenylalanine will continue to hydrolyze to produce two independent amino acids-aspartic acid and phenylalanine.
