热风干燥对皂角刺干燥特性及其生物活性组分的影响
Effect of Hot Air Drying on the Drying Characteristics and Bioactive Components of Gleditsia sinensis Lam.Thorns
摘要
Abstract
Using Gleditsia sinensis Lam.thorns(GST)as raw material,hot air drying was applied for treatment.The moisture content,moisture ratio,drying rate,effective moisture diffusion coefficient(Deff),and activation energy of drying(Ea)of GST were selected as evaluation indicators to explore the effects of hot air drying temperature(30-70℃)on its drying characteristics,drying kinetics,biological composition and bioactivity.The results showed that the drying temperature had an impact on the content of total saponin,total phenol,total flavonoid and α-glucosidase inhibitory activity of GST.As the temperature increased,the drying time of the GST was shortened,the moisture ratio decreased,and the drying rate increased.The Deff was 2.34×10-10-4.00×10-10 m2/s,and the Ea was11.93 kJ/mol.With the increase of temperature,the inhibitory activity of total saponin,total phenol,total flavonoid and α-glucosidase in GST first increased and then decreased.At 60℃,the drying rate of GST was faster,total saponin(35.06±4.61 mg/g),total phenol(92.44±1.12 mg/g),total flavonoid(48.38±2.21 mg/g),and α-glucosidase inhibitory activity(59.36%±5.0%)reached the highest.The changes of epicatechin,taxifolin,rutin,quercetin,fisetin,and apigenin in the extract of GST were determined by high performance liquid chromatography(HPLC).The results showed that the contents of these six common polyphenols in GST at 60℃were significantly higher than those at other temperatures.The fitting results of kinetic model for the GST drying process showed that among the seven drying models,the Modified Henderson and Pabis model had the best fitting effect with R2 of 0.996.关键词
