Molecular structure:
Description:
Sodium alginate is white or light yellow powder, almost odorless and tasteless. Sodium alginate is soluble in water, but insoluble in organic solvents such as ethanol, ether, chloroform, etc. Sodium alginate is hygroscopic, and the amount of water contained at equilibrium depends on the relative humidity. Dried sodium alginate is quite stable in well-sealed containers at 25°C and below. Sodium alginate solution is stable at pH 5-9. The degree of polymerization (DP) and molecular weight are directly related to the viscosity of sodium alginate solutions, and the reduction in viscosity during storage can be used to estimate the degree of sodium alginate depolymerization. Sodium alginate with high degree of polymerization is less stable than sodium alginate with low degree of polymerization. Sodium alginate has been reported to undergo proton-catalyzed hydrolysis, which is time-, pH- and temperature-dependent. Propylene glycol alginate solution is stable at room temperature and pH 3-4; when pH is less than 2 or greater than 6, the viscosity will decrease rapidly even at room temperature.
Sodium benzoate is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is used most prevalently in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments.
Sorbic acid, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative,Sorbic acid is a colourless solid that is slightly soluble in water and sublimes readily.
Methyl benzoate is an organic compound. It is an ester with the chemical formula C6H5CO2CH3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
