摘要:
主要营养成分及药用成分测定结果表明:原木灵芝菌柄的粗蛋白、粗脂肪及氨基酸含量虽然较菌盖低,但含有0.98%多糖、0.12mg/g三萜酸(灵芝酸A、B、C),具有较高的药用价值;此外,菌柄必需氨基酸所含比例较高(E/T=0.659).因此,菌柄可以用于浸膏粉生产。提取试验结果表明:菌柄提取率为2.03%～2.06%,菌盖C级品达3.64%～3.76%,B级品达4.65%～4.85%;由不同原料生产的灵芝浸膏及浸膏粉的主要成分含量差异较大。按B级品+30%菌柄或C级品+20%菌柄投料,可以使浸膏提取率分别控制在3.02%～3.12%及3.92%～4.03%.采用这两种合理投料组成,生产出来的浸膏粉质量相当稳定,主要成分含量变化不大,从而实现对成品质量的有效控制。产品送检日本分析,质量合乎要求,其中多糖含量还高于日本同类产品。
Abstract:
Main nutritional and medicinal components of pileus and stem of log cultivated Reishi (G.lucidum) were analysed.The results showed that contents of protein,fat and amino acids of the stem were lower than the pileus,but polysaccaridae and triterpenois acids were 0.98% and 0.12 mg/g respectively.In addition,the ratio of essential amino acids was higher than the pileus.Therefore,the stem can be applied into the extract production.Experiment results showed that extract rates of stem,pileus of grade C and B were 2.03%～2.06%,3.64%～3.76% and 4.65%～4.85% respectively,and there were obvious differences among main components in their extracts or extract powders.The extract rate can be controlled within the ranges from 3.03% to 3.12% and 3.92% to 4.03%,while two suitable material compositions (pileus of grade B with 30% stem and pileus of grade C with 20% stem) were adopted and the product quality was relatively stable.Thereby,the product quality was effectively under the control.Our extract powder samples were analysed and checked in Japan,and were identified up to standard.The content of polysaccaridae was higher than the similar product in Japan.
