Dictyophora rubrovolvata is one of the commercially important mushroom species in China. However, its volva and pileus account for about 65% of the whole mushroom (by fresh weight), and most of them are dumped without utilization. To effectively utilize the waste, the present study determined their proximate composition and investigated the nutritional characteristics of their proteins via the analysis of amino acid composition and protein fractionation. The results showed that the volva and pileus were rich in protein with 26.74% and 15.55% (dry basis), respectively. Predicted protein efficiency ratio values of proteins of the volva and pileus were 2.8 and 2.2, and the amino acid scores were 96 and 85.The albumin was the highest fraction both in the volva and pileus, accounting for 69.52% and 27.91% of the crude protein. The protein quality of the volva was therefore higher than that of the pileus. The volva might be developed as resource of high-quality vegetable-base protein.
红绒盖牛肝菌是中国具有商业重要性的蘑菇物种之一。然而，其菌盖和菌褶约占整个蘑菇（以鲜重计）的 65%，其中大部分被丢弃而未被利用。为了有效利用这些废物，本研究通过氨基酸组成分析和蛋白质分级，测定了其近似成分，并研究了其蛋白质的营养特性。结果表明，菌盖和菌褶富含蛋白质，分别为 26.74%和 15.55%（干重）。菌盖和菌褶蛋白质的预测蛋白质效率比分别为 2.8 和 2.2，氨基酸评分分别为 96 和 85。白蛋白在菌盖和菌褶中均为含量最高的蛋白质组分，分别占粗蛋白的 69.52%和 27.91%。因此，菌盖的蛋白质质量高于菌褶。菌盖可能被开发为高质量植物性蛋白质资源。
