响应面法优化萌发藜麦芽乳发酵工艺
Process Optimization by Response Surface Methodology for the Development of a Beverage Based on Lactic Acid Fermentation of Quinoa Malt
摘要
Abstract
The purpose of this study was to investigate the effect of fermentation conditions on the acidity and viable bacterial count of a beverage developed from quinoa malt fermented with lactic acid bacteria.Mixed starter cultures of Lactobacillus plantarum and Lactobacillus casei were used for the fermentation.One-factor-at-a-time method and response surface methodology were used to explore the effect of starter culture composition,inoculum amount and fermentation time on fermentation.A ratio of L.plantarum to L.casei of 2.5:1,an inoculum amount of 3% and a fermentation time of 10.3 h were found to be optimal.Under these conditions,the acidity of fermented quinoa malt was 85.32 °T and the viable count was 9.21 (lg(CFU/mL)),which were in good agreement with the predicted values.The result showed that homogenized quinoa malt was suitable for the growth of lactic acid bacteria.关键词
