摘要
为研究不同干燥方式对大球盖菇品质和抗氧化活性的影响,采用热风干燥、热泵干燥、真空冷冻干燥3种方式对大球盖菇进行脱水干燥,分析了不同干燥方式对大球盖菇感官品质、复水性能、风味功能成分含量以及抗氧化活性的影响.结果表明:真空冷冻干燥处理下大球盖菇的感官总评分为20.81分,复水比为7.09,持水力为5.18 g/g,有机酸含量为258.65 mg/g,粗多糖含量为49.62 mg/g,总黄酮含量为8.63 mg/g,上述指标在3种干燥方式下均为最高,且显示出更高的抗氧化活性;热风干燥处理下大球盖菇的游离氨基酸和总多酚含量高于其他干燥方式,其他指标均表现为热泵干燥处理优于热风干燥处理.综上,真空冷冻干燥处理是获得大球盖菇干制品最好的加工方式,热泵干燥处理次之,热风干燥处理的效果最差.综合考虑干燥成本和效率等因素,在生产实践中宜采用热泵干燥方式.
Abstract
In order to study the effects of different drying methods on quality and antioxidant activity of Stropharia rugosoannulata,three different drying methods including hot air drying,heat pump drying and vacuum freeze drying were used to analyze sensory quality,rehydration performance,flavor functional component and antioxidant activity of Stropharia rugosoannulata.The results showed that Stropharia rugosoannulata with vacuum freeze drying treatment had the best sensory score(20.81),rehydration rate(7.09)and holding water capacity(5.18 g/g),and had the highest organic acids content(258.65 mg/g),polysaccharides(49.62 mg/g)and flavonoids(8.63 mg/g).At the same time,it also showed higher antioxidant activities.Stropharia rugosoannulata with hot air drying treatment had the highest content of free amino acids and crude polyphenols,but other indicators are worse than those of heat pump drying.In conclusion,vacuum freeze drying is the best method to obtain dried products of Stropharia rugosoannulata,followed by heat pump drying,and hot air drying is the worst.However,if the drying cost and efficiency are considered comprehensively,the heat pump drying is a more reasonable drying method in production practice.
