文摘以新鲜红托竹荪为原料,研究传统煤火干燥(Coal Fire Drying,CFD)、空气源热泵干燥(Air Source Heap Pump Drying,ASHPD)、真空微波-电热鼓风组合干燥(Microwave Vacuum Drying in Combination with Forced Air Drying,MVD+FAD)和真空冷冻干燥(Vacuum Freeze Drying,VFD)四种干燥方式对其外形、色泽、营养成分、氨基酸组成和含量、质构特性和微观结构的影响。结果表明:VFD可以最大限度地保持竹荪菌柄和菌裙外形,其蛋白质、粗纤维和总氨基酸含量最高,色泽与鲜品最接近(ΔE=3.60);ASHPD制备的竹荪菌柄和菌裙外形保持较好,脂肪含量最高,蛋白质保留效果较好。竹荪的鲜甜味/苦味的值为VFD组(4.99%)>MVD+FAD组(4.66%)>ASHPD组(4.50%)>CFD组(4.37%)。VFD制备的竹荪组织结构较脆,组织内部结合力较小,与鲜品相似,而另三种干燥方式制备的竹荪内部结合力较大,抵抗受损能力较强,吞咽前需要更多的能量才能嚼碎。此外,VFD和ASHPD制备竹荪的细胞状结构明显,VFD更好的保持了竹荪原有的细胞状结构。干燥方式的综合评价结果为VFD>MVD+FAD>ASHPD>CFD。综上,VFD为红托竹荪较理想的干燥方式,但其应用成本较高;在实际生产中,ASHPD是比较有推广价值的干燥方式。
文摘为提高红托竹荪干燥品质并获得最佳干燥工艺,采用真空红外干燥(vacuum infrared drying,VID)、气流冲击干燥(air impingement drying,AID)、控湿干燥(moisture control drying,MCD)等不同干燥方式对红托竹荪进行对比研究,以热风干燥(hot air drying,HAD)作为对照组,研究不同干燥方式及温度对红托竹荪干燥品质的影响。试验结果表明不同干燥方式对竹荪宏观品质产生了显著影响,其中MCD可获得最小的色差∆E和收缩率,AID则能够保证较高的复水比;干燥速率方面,MCD在前期能够获得较高的干燥速率,但后期干燥速率会放缓,而AID在整个干燥过程都具有较高的干燥速率,干燥时间较短;在成分保留上,MCD可以保留较高含量的多糖、三萜和黄酮,而采用VID可以有效保护多酚。单位能耗随干燥温度的升高明显降低,不同方式下VID的干燥能耗值整体偏大,MCD的单位能耗最低(18.82 kW·h/kg)。通过主成分分析法,上述干燥方式对红托竹荪综合评分后得到的结果排序为:MCD>AID>VID>HAD,MCD干燥方式中采用60℃相对湿度为40%,保湿时间15min的干燥工艺综合品质较佳,在此加工方式下的红托竹荪综合评分为2.94,该研究可为红托竹荪高品质干燥提供一定参考。
