Han, Yingying;Du, Jinhua;Song, Zhaolin published 《Effects of the yeast endogenous β-glucosidase on hawthorn (Crataegus pinnatifida Bunge) wine ethyl carbamate and volatile compounds》 in 2021. The article was appeared in 《Journal of Food Composition and Analysis》. They have made some progress in their research.Quality Control of Ethyl tetradecanoate The article mentions the following:
In this study, twenty-three com. yeasts were inoculated into hawthorn (Crataegus pinnatifida, Bunge (Rosaceae)) extracted juice to explore their fermentation characteristics, beta-glucosidase activity, Et carbamate production, volatile compounds of resulted wines, along with the relationship of beta-glucosidase activity on Et carbamate and volatile compounds beta-Glucosidases were yeast and culture medium dependence. However, their activities in wines were merely 9.50%-30.7% of that in YM (yeast extract, malt extract) medium. Et carbamate, which was also yeast dependence, was correlated with beta-glucosidase (0.426*) whereas less affected by physicochem. indexes of hawthron wines. Volatile compounds were not correlated with beta-glucosidase activity whereas related to the physicochem. indexes. alpha-Terpineol, which was originally existed in the juice, was increased by the fermentation, while (-) linalool oxide, rose oxide, linalool, terpinen-4-ol, citronellol and nerolidol were newly produced during fermentation FC9 was the most optimal yeast for hawthorn wine making because of its excellent ethanol production, higher beta-glucosidase activity, moderate amounts of volatile compounds, best sensory score and lower EC (5.48μg/L). And Ethyl tetradecanoate (cas: 124-06-1) was used in the research process.
Ethyl tetradecanoate(cas: 124-06-1) is a labeled component from essential oil of natural hawthorn perfume. Also frequently used in cosmetics, soaps, and flavorings.Quality Control of Ethyl tetradecanoateEthyl myristate is a long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of myristic acid with the hydroxy group of ethanol.
