采用热风干燥、热泵干燥、微波热泵耦合干燥、热泵梯度升温干燥、热泵梯度降温干燥等干燥方式,探究不同干燥方式对灵芝子实体感官、营养及理化品质的影响.结果表明,微波12 min+60℃热泵干燥脱水效率最高,较单一热风干燥至少缩短180 min;微波4 min+60℃热泵干燥色泽保持相对较好;微波12 min+60 ℃热泵干燥粗多糖含量最高,较60℃热风干燥提高了63.26%;热泵梯度降温干燥对DPPH自由基的清除能力最强;60℃热泵干燥水溶性指数最高.从提高生产效率和营养成分保留率角度考虑,优先选择微波12 min+60 ℃热泵干燥方式;从产品良好色泽角度考虑,优先选择微波4 min+60 ℃热泵干燥方式;从产品良好功能活性角度考虑,优先选择热泵梯度降温干燥、60 ℃热泵干燥方式,为灵芝子实体干燥方式的选择提供理论依据.
Effects of Different Drying Methods on the Drying Quality of Ganoderma lucidum Fruit Body
Hot air drying,heat pump drying,microwave heat pump coupling drying,heat pump gradient heating drying,heat pump gradient cooling drying and other drying methods were used to explore the effects of different drying methods on the sensory,nutritional and physical and chemical quality of Ganoderma lucidum fruit body.The results showed that the dehydration efficiency of microwave 12 min+60 ℃ heat pump was the highest,which was at least 180 min shorter than that of single hot air drying.Microwave 4 min+60 ℃ heat pump color retention was relatively good.The content of crude polysaccharide was the highest when microwave heat pump drying for 12 min+60 ℃,which was 63.26%higher than that when hot air drying at 60 ℃.Heat pump gradient cooling drying DPPH free radical scavenging ability was the strongest.The water solubility index of 60 ℃ heat pump was the highest.In order to improve the production efficiency and nutrient retention rate,the microwave 12 min+60 ℃ heat pump combined drying method was preferred.Considering the good color and quality of the product,the microwave 4 min+60 ℃ heat pump combined drying method was preferred.From the perspective of good functional activity quality of the product,the heat pump gradient cooling drying and 60 ℃ heat pump drying methods were preferred to provide a theoretical basis for the selection of Ganoderma lucidum fruit body drying methods.
