Buffered Lactic Acid
Description
Buffered lactic acid is preparation synthesized from lactic acid and sodium lactate, suitable to be used to adjust pH value. Clarify the liquid transparently for being colorless or a little yellow of this product; Gentle saline taste; No smell or take the special smell slightly.
Applications
Buffered lactic acid is pH regulator with buffering effect. It the dosage is mistaken slightly, pH will not be influenced. Has bacteria inhibition effect, can effectively strengthen or resist oxidation, and extend storage period. Can also be used as sour flavor, with mild sourness. Can improve the appearance, taste, elasticity, viscosity of flour products. Take effect to protein in flour, and can bring rich meshes to the flour paste. Can improve the viscosity, softness, apperance and flavor of flour. Can make the boiling of noodle made of flour or starch easier. In candy, it can reduce the vice effect of souring agent, and maximize the transversion of sugar and degradation of gelatin.
