Use
Dehydroacetic Acid (DHA) is a preservative that is a crystalline powder with a solubility of less than 0.1 g in 100 g of water at 25°C. It can undergo a variety of chemical reactions which give it utility in many applications. It is used at 0.01–0.5% for microbiological growth inhibition in various foods. It is used for cut or peeled squash, with no more than 65 ppm remaining in or on the prepared squash.
