Optimization of Loquat Enzyme Fermentation Process and Quality Analysis
Using fresh loquat as raw material,a mixed lactic acid bacteria fermentation was used to prepare loquat enzyme.Using the activity of superoxide dismutase(SOD)as an antioxidant activity indicator,single factor and orthogonal experiments were used to optimize the fermentation process of loquat enzyme,and its quality was analyzed.The results showed that inoculate 0.15％mixed lactic acid bacteria,add 18％white sugar,and ferment at 30 ℃ for 6 d.The loquat enzyme obtained under optimal condition has an SOD activity of 104.6 U/mL and a sensory score of 89 points.
