On June 30, 2022, Jia, Wei; Di, Chenna; Zhang, Rong; Shi, Lin published an article.Name: Diethyl succinate The title of the article was Ethyl carbamate regulate esters degradation by activating hydrolysis during Baijiu ripening. And the article contained the following:
The presence of Et carbamate in traditional fermented food is a public health concern for the FDA. The effect of forced photoirradiation (0-150,000 lx) and thermal stress (4, 25, 40 °C) on Et carbamate (0-150 μg/L) on physiol. characteristics of Baijiu, such as esters content, photochem. degradation, and hydrogen-bond interaction efficiency were monitored by ultra high performance liquid chromatog. quadrupole-orbitrap and the dynamic changes by digital foodomics anal. Furthermore, 748 trace components covering 11 subclasses were identified in Baijiu and 71 esters were screened by Spearman′s correlation, fold changes, P values and VIP values. A forward stepwise multiple regression and discriminant anal. were performed for predicting the content of esters from appearance characteristics obtained by foodomics anal., reaching R-square values up to 0.91. A reduction of the present variation in Et lactate, Et caproate, di-Et succinate, Et oleate and Et linoleate concentration could possibly result in a better understanding of the Et carbamate effects. Et carbamate was found to cause esters hydrolysis through inter-mol. interaction in various species of alc. drinks. It was demonstrated that the light exposure level and thermal intensity applied for Et carbamate-spiked Baijiu samples did not unambiguously influence esters concentration in Baijiu. Future research should focus on moderate light exposure level and thermal stress and should aim at reducing natural Et carbamate by more closely controlling the esters content of the ripening degree. The experimental process involved the reaction of Diethyl succinate(cas: 123-25-1).Name: Diethyl succinate
