文摘采集贵州省部分分布区域内野生红托竹荪(Dictyophora rubrovolvata Zang, Ji et Liou.)健壮子实体为育种亲本,经系统选育,贵定县石板村红托竹荪成为高产、优质、抗逆性强的优良品种。该菌株菌丝在5℃~28℃均能生长,子实体生长最适温度为18℃~24℃;菌丝萌发后形成原基能力强;生长季节为3月到10月,平均单产量为0.15 kg·m-2,生物转化率为32%。采用阔叶木屑及腐殖土覆土栽培。该品种红托竹荪在不同海拔试验中产量稳定,菌株表现出均一性、稳定性,因此具有较好的商业价值。
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。
