Comparison of different drying methods on chayotes powder Vc retention rate, color, density, dispersion, yield and sensory quality. The results show that the ratio, bulk density, dispersion and sensory evaluation of these aspects is better than that of vacuum drying and hot air drying spray drying processing of preserved chayote powder in Vc. Vacuum drying and spray drying of Chayote powder is close to the total color difference and better than hot air drying. The rate of hot air drying and vacuum drying was significantly higher than that of spray drying. Comprehensive consideration, spray drying can maintain chayotes powder product quality, and vacuum drying to obtain a higher product yield. Actual production can be selected according to the product positioning. Key words： Chayote powder; Quality; Air drying; Vacuum drying; Spray drying 中图分类
