Effects of Different Cooking Methods on Nutritional Composition of Flammulina filiformis
[Objective]In order to explore the influence of different cooking methods on the nutrients and active ingredients of Flam-mulina filiformis,and determine the best cooking method to retain the nutrients of F.filiformis.[Method]The effects of steaming,boiling,frying and microwave on the contents of protein,fat,reducing sugar,polysaccharide,polyphenol and flavonoid in the nutrients of F.filiformis were compared.[Result]The content of F.filiformis flavonoids in increased significantly by 13.47%.The contents of protein,fat,reducing sugar,polysaccharide and polyphenol decreased by 28.70%,26.99%,38.45%,35.03%and 49.94%,respectively.After boiling,the content of flavonoids increased significantly by 9.25%.Protein,fat,reducing sugar,polysaccharides and polyphenols decreased by 61.86%,28.32%,45.31%,62.95%and 60.58%,respectively.The fried F.filiformis was similar to the boiled one,except that the content of flavonoids in the fried F.filiformis was significantly reduced by 13.31%.Microwave had no significant effect on fat and polysaccharide in F.filiformis,while the contents of protein,reducing sugar,polyphenols and flavonoids decreased by 20.52%,38.90%,18.27%and 9.42%.[Conclusion]The fried and boiled F.filiformis lost more nutrients,while steaming and microwave,especially microwave,could better retain the nutrients in F.filiformis.
