Sodium benzoate Food-grade purity of 99%

タイトルまたは説明

Benzoic acid is also known as benzoic acid and, therefore, also known as sodium benzoate, sodium benzoate. Benzoic acid at room temperature, insoluble in water, in the air (hot air), micro-volatile hygroscopic about room temperature 0.*4g/**0ml; but soluble in hot water; soluble in ethanol, chloroform, and non-volatile oil.More choice in the use of sodium benzoate; benzoic acid and sodium benzoate, and corrosion resistance traits are similar. Sodium benzoate is mostly white granules, odorless or microstrip benzoin smell, taste sweet, there is convergence; soluble in water (room temperature) *3.0g/**0ml about, PH 8; sodium benzoate is also acidic preservative in alkali medium sterilization, antibacterial effect; corrosion optimum pH is 2.**4.0, 5% solution in PH5.0 bactericidal effect is not very good. Sodium benzoate lipophilic large, easy to penetrate the cell membrane into the cell body to interfere with the cell membrane permeability, inhibition of membrane uptake of amino acids; enter the cells in vivo acidification of intracellular ionized alkaline reserve, and inhibits the activity of the cells of the respiratory enzymes, prevent condensation reaction of acetyl coenzyme A, which play the purpose of food preservation
