Abstract
Objective：The nutrition components and value of Collybia albuminosa were systemati-cally determined in the experiment.Method：The contents of nutrition components were determined with national standards and common methods.Result：The contents of crude protein,total polysaccharide,crude fat,crude fiber,ash and water in the dry sample were：32.82%,26.79%,4.40%,6.38%,7.02% and 13.08%.The extraction rate of crude polysaccharide after being decolorized and deproteinization came to 3%.The Mp of Collybia albuminosa polysaccharides were 15762,724871,18251u,respectively.The total amino acids in the fruit body of Collybia albuminosa were 28.51%,including 17 kinds of amino acids.Essential amino acids were 40.82% in total amino acids.Amino Acid Score（AAS）,Chemical Score（CS）,Essential Amino Acid Index（EAAI）and Nutritional Index（NI）were 87,70,74.78 and 24.54,respectively.Conclusion：Collybia albuminosa has high protein,low fat,low fiber.It also had components which have pharmacological effects,for example polysaccharides.It was a kind of mushroom with good nutrition value and economic value.关键词
