不同培养料对秀珍菇子实体蛋白质营养评价的影响

Effect of Different Kinds of Composts on the Nutritional Evaluation of the Protein inPleurotus geesteranus Fruitbodies

研究了不同培养料对秀珍菇 (PleurotusgeesteranusSinger)子实体蛋白质营养价值评价的影响。结果表明 ,圆叶决明培养料 (配方 2 )栽培的秀珍菇子实体蛋白质的化学评分 (CS)、氨基酸评分 (AAS)、必需氨基酸指数 (EAAI)、生物价 (BV)和氨基酸比值系数分 (SRCAA)分别为 6 1.10、77.10、78.92 ,74 .39和 83.5 0 ,比配方 1(对照 )、配方 3、配方 4和配方 5培养料栽培的秀珍菇子实体蛋白质的分别提高 2 3.6 8%、2 2 .5 8%、0 .83%、1.0 6 %、9.0 1% ,3.2 1%、17.35 %、0 .6 4%、0 .83%、9.4 4% ,0 .6 6 %、17.35 %、3.19%、3.81%、8.5 8%和 4 8.30 %、5 0 .0 0 %、4 .92 %、5 .83%、15 .33% ,均居 5种参比培养料栽培秀珍菇子实体蛋白质的第一位 ;营养指数 (NI)为 2 6 .0 6 ,居第二位。这些结果证实 ,圆叶决明培养料栽培的秀珍菇子实体蛋白质具有较高的营养价值 。

The effect of different kinds of composts on the nutritional value evaluation of the protein in Pleurotus geesteranus Singer fruitbodies of was investigated. It was confirmed in our experiments that the chemical score (CS),amino acid score (AAS),essential amino acid index (EAAI),biological valence (BV) and score of ratio coefficient of amino acid (SRCAA) in the protein of P.geesteranus fruitbodies cultivated with Chamaecrista roturdifolia compost (formula 2) were 61.10,77.10,78.92,74.39 and 83.50 resp, all held the first place; and that its nutritional index (NI) was 26.06, it held the second place, compared with that of the protein in P.geesteranus fruitbodies cultivated with other 4 kinds of composts tested. And the CS,AAS, EAAI,BV and SRCAA in the protein of P.geesteranus fruitbodies cultivated with C.roturdifolia compost were 23.68%,22.58%, 0.83%, 1.06%,9.01%;3.21%,17.35%,0.64%,0.83%,9.44%;0.66%,17.35%,3.19%,3.81%,8.58% and 48.30%,50.00%,4.92%,5.83%, 15.33% higher than that of the protein inP.geesteranusfruitbodies cultivated with the composts composed by formula 1 (CK), formula 3, formula 4 and formula 5 resp.. The results showed that the protein of P.geesteranus fruitbodies cultivated with C.roturdifoliacompost was provided with higher nutritional value, and C.roturdifolia was proved to be a high guality component for composing P.geesteranus compost.
