Nutritional Evaluation on Proteins in Fruits of 31 Loquat Genotypes
摘要
Abstract
The amino acids (AA) in the fruits of 31 loquat genotypes ,including 28 cultivars and 3 wild genotypes , from 5 countrieswere assayed .The nutritional value of the proteins was evaluated according to 4 non‐biological methods ,i .e .,chemical score (CS) ,amino acid score (AAS) ,essential amino acid index (EAAI) and score of ratio coefficient of amino acid (SRC) .The primary limiting AAs in the fruits were sulfur‐containing methionine and cystine .The ranges of CS varied from 8.36 to 21.46 ,AAS from 9.87 to 23.1 ,EAAI from 42.83 to 65.68 ,and SRC from 54.90 to 63.20. In particular ,16 genotypes were above 60on SRC .CS ,AAS and SRC of the genotypes with orange flesh were significantly higher than those of the genotypes with yellowish white flesh (P< 0.05) , whereas the EAAI were similar in both genotypes (P>0.05) .The EAAI of the wild loquats was much higher than those of the cultivated species ( P < 0.01 ) , whereas there were minor differences in CS , AAS , and SRC . Furthermore ,CS ,AAS ,EAAI ,and SRC were similar among genotypes from different regions .The 31 genotypes were classified into 3 categories by cluster analysis .关键词
