摘要
在单因素试验的基础上,应用响应面分析法对圣女果百香果复合发酵饮料工艺进行优化,并对发酵后的品质指标进行了测定。结果表明,各因素对圣女果百香果复合发酵饮料中感官评分影响大小依次为果汁配比>发酵时间>菌种添加量>发酵温度;最优发酵工艺条件为:圣女果:百香果汁配比6∶1、发酵时间31 h、菌种添加量3%、发酵温度37℃。在此优化条件下,圣女果百香果复合发酵饮料感官评分达82分,酸甜宜口、风味独特,发酵后复合发酵饮料的pH、可溶性固形物、总酸、还原糖、总酚、总黄酮、番茄红素、维生素C、乳酸菌总数分别为3.30、11.50%、5.95 g/100 ml、6.68 g/100 g、40.03 mg/100 g、6.83 mg/g、32.83 mg/100 g、23.31 mg/100 g、5.2×10^6 CFU/mL。
On the basis of single factor experiments,the fermentation process of compound fermented beverage with cherry tomato and passion fruit was optimized by response surface methodology,and the quality indexes of the beverage were determined after fermentation.The results showed that the effect of each factors on the sensory evaluation score in order was fruit juice ratio>fermentation time>inoculum>temperature.The optimum fermentation conditions were cherry tomato to passion fruit juice ratio 6:1,fermentation time 31 h,inoculum 3%,temperature 37℃.Under these optimal conditions,the sensory score of the compound fermented beverage with cherry tomato and passion fruit was 82.The beverage had mild sweet and sour with the unique flavor.After fermentation,the pH,soluble solid,total acid,reducing sugar,total phenol,total flavonoid,lycopene,vitamin C contents and lactic acid bacteria counts were 3.30,11.50%,5.95 g/100 ml,6.68 g/100 g,40.03 mg/100 g,6.83 mg/g,32.83 mg/100 g,23.31 mg/100 g and 5.2×10^6 CFU/ml,respectively.
