New Normal Temperature Drying Process of Cervi Cornu Pantotrichum with Lingnan Characteristic

Abstract:

Objective: To introduce a new room temperature drying process with separator feature,optimize this drying process of Cervi Cornu Pantotrichum with Lingnan characteristic and analyze quality of its dried products. Method: UV spectrophotometry was employed to determine the content of total free amino acids with detection wavelength at 567 nm.With composite score of appearance,contents of alcohol-soluble extract and total free amino acids as index,orthogonal test was adopted to optimize drying process by taking material density,drying temperature and timeas factors. Result: Optimal process conditions was as following:dried 4 h at 35 ℃ when material density of 9 g.Contents of alcohol-soluble extract and total free amino acids were 9.50%and 1.16%,respectively. Conclusion: This new normal temperature drying process is energy-efficient,convenient and feasible.
