Comparison of Nutritional Constituents of Lentinus edodes Cultivated in Different Mulberry Sawdust Substrate
摘要
Abstract
[Objective]To analyze nutrient and amino acid composition of fresh Lentinus edodes cultured in different proportions of mulberry sawdust substrate.[Method]Lentinus edeinus"808"was used as the test strain.Different proportions of mulberry sawdust substrate(0%～40%)were used for clinker planting of Lentinus edeinus.The composition of water,crude protein,crude fiber,ash,crude polysaccharide,crude fat,and amino acids in the fruiting bodies of the first harvest was determined.The RAA,RC,and SRC were calculated.Based on principal component analysis,amino acid characteristics of Lentinus edodes cultivated with different proportions of mulberry cuttings were studied,and nutritional differences of Lentinus edodes were comprehensively evaluated.[Result]The tested mushroom contained 16 kinds of amino acids,including 7 kinds of essential amino acids,the total amino acid content ranged from 2.100 g/100 g to 2.664 g/100 g,and the TIAA/TNIAA value ranged from 48.34%to 54.64%.TIAA/TAA ranged from 32.57 to 35.33.Four principal components were extracted from principal component analysis,and the cumulative variance contribution was 84.302%.The amino acid score of Lentinus edodes cultured in a substrate of 40%mulberry sawdust was the highest.Essential amino acid content was close to the WHO/FAO model,and Thr and Lys content was abundant.The first limiting amino acid is the total amount of Met and Cys.The SRC values ranged from 63.10 to 79.98,and the nutritional value of the fungal protein grown in a substrate of 40%mulberry sawdust was the highest.Therefore,it was concluded that a substrate containing 30%to 40%mulberry substrate instead of wood waste has higher protein nutritional value for growing Lentinus edodes.The content of crude protein 3.02 g/100 g to 3.76 g/100 g,coarse fibre 1.03 g/100 g to 1.10 g/100 g,ash 0.72 g/100 g to 0.88 g/100 g.crude polysaccharides 0.88 g/100 g to 1.02 g/100 g,crude fat 0.35 g/100 g to 0.45 g/100 g,proves that Lentinus edodes has high protein content,low fat,low fibre and rich in nutrients.[Conclusion]The cultivation of Lentinus edodes with 30%to 40%mulberry sawdust substrate has higher nutrition.It provides a theoretical basis for better development and use of the"mulberry mushroom"and scientific composition of the diet.关键词
