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).

Im confused as I look at your compound dimethylcarbonate no 818758 its says Assay > 97 % in the specification but beneath in the text on the website it says Assay >99%? Whats the purity and when did you change from 99 to 97 % if its the correct number
1 answer-
The minimum purity specification for this product was changed from 99% to 97% in November of 2022. The specification was updated in the product properties section but not the Analysis Note. This content has now been corrected. Thank you for bringing this to our attention.
