Vidal grape grown in Ili, Xinjiang Autonomous Region, is one of few grapes used to ferment ice wine in China. Microbial community structure and volatile composition during the spontaneous fermentation of ice wine made from Vidal grapes in Ili were investigated using amplicon sequencing technol. and headspace solid-phase microextraction/gas chromatog.-mass spectrometer technologies. Among bacterial genera, Sphingobium, Pseudomonas and Sphingomonas gradually decreased, while Lactobacillus and Streptococcus increased during the spontaneous fermentation process. As regards fungi, the relative abundance of Vishniacozymaand Cladosporium reduced, but Hanseniaspora sharply raised. Addnl., correlations between microbes and volatile compounds were constructed based on multivariate data anal. The results revealed that the functional core microbiota (mainly composed of eight bacterial genera and nine fungal genera) during ice wine fermentation showed considerable correlations with the formation of twenty-four volatile compounds in ice wine made from Vidal grapes. For example, Saccharomyces was pos. correlated with ethanol, Et acetate and isoamylol; Hanseniaspora and Candida were neg. correlated with hexanol; and Lactobacillus and Streptococcus were pos. correlated with 2,3-butanediol, ethanol, Et acetate, isoamylol and isoamyl acetate. This studyprovides a reference for understanding the process of ice wine fermentation and improving the quality of ice wine made from Vidal grapes. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
