Preparation method and detection method of healthy nutritional fruit wine for brewing yeast Bei-29

Abstract

The invention relates to the technical field of wine and fruit wine brewing, in particular to a preparation method and detection method of healthy nutritional type fruit wine for brewing yeast Bei-29.Optimal rhodotorula mucilaginosa and saccharomyces cerevisiae are subjected to mixed fermentation, so that the content of carotenoids (astaxanthin, beta-carotene, zeaxanthine and lycopene) in fermented raw wine is increased, and the components and content of norisoprene, terpene aroma substances and fruity ester substances are increased. The method provided by the invention comprises the steps of1) performing activation culture on optimized rhodotorula mucilaginosa Bei-29; 2) performing amplification culture on the rhodotorula mucilaginosa Bei-29 subjected to activation culture; 3) performing mixed fermentation on the rhodotorula mucilaginosa Bei-29 subjected to amplification culture and the saccharomyces cerevisiae, and then detecting the carotenoids and norisoprene aroma compounds.
