不同干燥方式对桑黄菌品质的影响
Effects of Different Drying Methods on the Quality of Inonotus hispidus
摘要
Abstract
Effects of drying methods on the quality of Inonotus hispidus were studied.The fruit bodies of I.hispidus were treated by five different drying methods.The basic physicochemical components,color value,antioxidant activity and volatile components of I.hispidus were determined.Correlation analysis and principal component analysis were used to comprehensive evaluate the effects of different drying methods on fruiting body quality.The results showed that different drying methods had different effects on the quality of I.hispidus,among which the total flavonoid content,total reducing power and color difference all showed significant differences.The total polyphenols,total flavonoids and total reducing power were the highest in the fruiting bodies treated by microwave drying.The scavenging rate of DPPH free radical was the highest in the fruiting bodies treated with hot air drying.The total polysaccharide content and the relative content of hexyl alcohol were the highest and the color value was the best in the fruiting bodies treated by freeze drying.Different drying methods had significant differences in physicochemical indexes of the fruiting bodies,among which the total flavonoid content,total reducing power and color difference were significantly different.Correlation analysis showed that there was a certain correlation among the physicochemical indexes,among which the total polyphenols,total flavonoids and total reducing power showed a very significant positive correlation,and the total polysaccharide content,color value and volatile substances showed a very significant positive correlation.Principal component analysis showed that the comprehensive score of freeze-drying was the highest and was suitable for the drying of I.hispidus.This experiment provided certain theoretical support for the drying and industrial development of polyporus umbellatus.关键词
