Abstract: Disclosed is a method for improving quality of cured loin ham mediated by sorbitol, belonging to the field of food processing. The method comprises the following steps: treating loin with curing material containing sorbitol, inoculating bacterial suspension, and fermenting at constant temperature and humidity to obtain sorbitol-mediated curing loin ham. Through experiments, it is found that the salt content, pH value and aw of sorbitol group are lower than those of control group in the whole production and processing process; only Lactobacillus is the dominant genus in the control group, while Staphylococcus and Lactobacillus are the dominant genera in the sorbitol group.

Abstract: The present invention relates to a preparation method for a chiral intermediate for use in statins, acquired with chloroacetic acid and benzyl alcohol as starting materials via a series of reactions, namely etherification, condensation, substitution, and asymmetric reduction. The preparation method provided in the present invention has a novel route of synthesis, allows an intermediate compound to be introduced conveniently into the chiral center of a glycol via enzyme reduction, and not only is low in costs, but also is reliable in quality. The route of synthesis provided in the present invention uses raw materials of low costs, has an easy to operate process, and provides a final product of great purity and high yield.
