Application
Dehydroacetic acid used as preservatives in food and drinks to prevent the growth of mold, yeast and fungi. In general the salts are preferred over the acid form because they are more soluble in water. The optimal pH for the antimicrobial activity is below pH 6.5 and sorbates are generally used at concentrations of 0.025% to 0.10%. Adding sorbate salts to food will however raise the pH of the food slightly so the pH may need to be adjusted to assure safety.
Docosahexaenoic acid/ DHA, is a member of ω-3 polyunsaturated fatty acids, which has important physiological regulation function for human.
