Description

Application

• Enhancing microbial control in beverage production: A study evaluated the combined effect of high pressure processing and dimethyl dicarbonate (DMDC) for inactivating foodborne pathogens in apple juice, demonstrating DMDC′s efficacy as a microbial control agent in beverage preservation (Petrus et al., 2020).
• Alternative to heat treatment in juice fermentation: Research explored the effects of dimethyl dicarbonate (DMDC) on the fermentation of litchi juice by Lactobacillus casei, presenting DMDC as a viable non-thermal preservation method that could replace traditional heat treatments in the food industry (Yu et al., 2014).
