原花青素双歧杆菌合生元酸奶的研制及品质分析
Research on preparation and quality analysis of procyanidin-Bifidobacterium synbiotic yoghurt
摘要
Abstract
Synbiotics have been widely studied and applied as food additives due to their unique biological activities.Hence,the com-bination of Bifidobacterium BB12 and proanthocyanidins was used to fortify the functionality of yoghurt.The effects of adding proanthocya-nidins,bifidobacteria,xylitol,and fermentation time on the sensory characteristics and physical and chemical indexes of yogurt were in-vestigated.Volatile compounds in yoghurt were determined by headspace solid-phase microextraction coupled to gas chromatography-mass spectrometry,and the rheological characteristics of yoghurt during storage were characterized by a rheometer.Results showed that the yo-ghurt had a uniform and delicate texture after optimization.The formulation of yoghurt was optimized as 0.035% proanthocyanidins,0.4% Bifidobacterium,and 10% xylitol.The fermentation conditions of yoghurt were at 45℃ for 12 h.The addition of Bifidobacterium BB12 and proanthocyanidins altered the flavor compounds,especially the increasing ketone(19.55%)and acid(15.27%)contents.At these con-ditions,the results of mass spectrometry show that there are significant differences in the thresholds of various flavor substances in com-pound yogurt compared with single-component yogurt,among which ketones were the highest,followed by acids.Yoghurt containing Bifidobacterium BB12 and proanthocyanidins showed a more stable structure,higher viscosity,and longer quality retention time than the blank yoghurt after low-temperature storage.This study can provide a basic data reference for the specific application and development of plant polyphenol synbiotics.关键词
