从啤酒废酵母泥中回收啤酒和啤酒酵母的研究

为了得到高附加值的产品,利用陶瓷膜分离设备从啤酒废酵母泥中过滤得到啤酒和啤酒酵母,啤酒用于后续纯生啤酒或者清酒的加工,啤酒酵母进入后续深加工系统。小试试验、中试试验和工业试验的结果表明:使用陶瓷膜分离设备处理啤酒废酵母泥,无废弃物排放,啤酒废酵母泥中啤酒回收率可达70%(质量分数)以上;与传统的板框过滤法相比,该方法动力消耗小、回收率高,回收的啤酒不含酵母细胞,浊度合格,达到了降低酒损、提高啤酒收率的目的,提高了企业经济效益;无废弃物排放,解决了环保问题,实现了资源的优化配置。     

Effects of selected antioxidants on physical and sensory characteristics of yeast bread containing flaxseed meal

Flaxseed has been identified as a potential functional food because of its high content of phytochemicals, alpha‐linolenic (α‐linolenic) acid and lignans. Flaxseed can be used in baked goods because of its minimal loss of α‐linolenic acid. Alpha‐linolenic acid is susceptible to oxidation and the development of off‐aromas and flavours in the food. The focus of this study was to determine the effectiveness of both synthetic and natural antioxidants that were incorporated into a yeast bread that contained 15% flaxseed as a partial replacement for bread flour. The study evaluated the effectiveness of the antioxidants on the physical and sensory characteristics of the bread. Physical properties, such as per cent moisture and loaf volume, were not affected (P > 0.05) by the antioxidants, but ascorbic acid, butylated hydroxytoluene and butylated hydroxyanisole, independently, had a softening affect (P < 0.05) on crumb firmness. Sensory analysis indicated significant (P < 0.05) changes in aroma, grainy taste, aftertaste and moistness in all bread samples regardless of antioxidant, however, only ascorbic acid was rated as effective in maintaining a softer (P < 0.05) crumb.
