| Benzoic acid, also known as benzoic acid, so called Benzoin Sodium Benzoate.Benzoic acid at room temperature, insoluble in water, in the air (especially hot air) in the micro-volatile,Hygroscopicity, about room temperature 0.34g/100ml; but soluble in hot water;Also soluble in alcohol, chloroform and non-volatile oil,Benzoic acid and sodium benzoate, and corrosion resistance traits are similar. Sodium benzoate particles mostly white, odorless or microstrip benzoin smell, taste sweet, with convergence; soluble in water (room temperature) 53.0g/100ml around, PH 8 percent;Acid preservative sodium benzoate is in the alkaline medium without bacteria, inhibition; its best PH is 2.5-4.0 corrosion in PH5.0 5% when sterilization is not a good solution. Sodium benzoate, pro-big oil, penetrating the cell membrane into the cell body, interference membrane permeability and inhibit the absorption of amino acids cell membrane; into the cell body ionizing acidification of alkaline storage cells and inhibit the activity of respiratory enzymes, prevent condensation of acetyl coenzyme A to play the purpose of food preservation. |
