摘 要：运用生物技术将菠萝汁经适当发酵制成果香浓郁,具有特殊风味的低醇菠萝汁发酵饮料,不仅能为菠萝原料的加工转化,提高菠萝的有效利用提供新的途径,也为日益丰富多彩的饮料市场增添了新的热带果蔬加工饮料产品。本文以菠萝全汁为原料,对菠萝果酒的加工工艺及影响菠萝果酒品质的关键性工艺参数进行了研究。采用感官评定法评价菠萝酒成品，优化发酵条件,结果显示: 按照0.5mg/L的比例向压榨后的果汁中添加果胶酶,并保温40℃作用2h后,采用一次加糖法将糖质量浓度调至每20g/100mL,添加亚硫酸为原溶液的1‰,主发酵温度26℃,发酵7d;后发酵温度15℃,发酵30d，最后采用蛋清澄清处理,75℃杀菌15min后,得到果香浓郁、色泽金黄、澄清透明的优质菠萝果酒。

Abstract: The use of biotechnology will be properly fermented pineapple juice-rich fruits of the system, has a special flavor of low-alcohol beverage fermented pineapple juice, pineapple, not only for the processing of raw materials, improve the effective use of pineapple provide a new way, as well as the increasingly rich and colorful Beverage market added a new tropical fruit and vegetable processing beverage products. This paper is study the fermentation technology of pineapple wine with the pure pineapple juice and the key technology parameters which have effect on the product quality. Use of sensory eva luation of wine eva luation of pineapple products, optimize the fermentation conditions, the results show that: The pineapple juice extracted from the pineapple was treated with the 0.5mg/L pectinase for 2h at 40℃, adding 20g/100mL sugar in one time, controlling respectively, Add biased towards Asia for the solution of potassium sulfate 1‰. Main fermentation temperature and back fermentation temperature at 26℃ for 7d and 15℃ for 30days, Finally a clarification egg white, After sterilization at 75℃for 15min , t he pineapple wine with full-bodied flavor , golden-yellow colour , high quality and good clarification level was obtained.
