13种植物源蜂花粉蛋白质的营养学评价

测定向日葵、益母草和五味子等3种植物源蜂花粉的蛋白质和氨基酸含量，并结合文献报道的向日葵和五味子蜂花粉及另外10种植物源蜂花粉的蛋白质和氨基酸含量数据，采用国际上通用的营养价值评价方法对13种植物蜂花粉的蛋白质含量、化学评分（chemical sore，CS）、必需氨基酸指数（essential amino acid index，EAAI）、氨基酸比值系数分（score of ratio coefficient of amino acid，SRCAA）、生物价（biological value，BV）和营养指数（nutritionalindex，NI）等进行综合评价。评价结果表明，蜂花粉的蛋白质含量为14.3%～29.0%，CS为64.4～89.3，EAAI为66.9～107.0，SRCAA为79.9～91.1，BV为61.2～104.9，NI为11.7～29.3；茶花蜂花粉的上述6项指标均高于平均值，分别为29.0、83.1、101.3、88.8、98.7和29.3，是所分析的13种蜂花粉中营养价值最均衡的蜂花粉。

Nutritional Evaluation of Bee Pollen Proteins from 13 Different Plant Species

The contents of proteins and amino acids of Helianthus annuus, Schisandra chinensis, Leonurus heterophyllus
bee pollens were determined. Based on the analysis data obtained in this study and those reported in literature for bee pollens
from Helianthus annuus and Schisandra chinensis as well as 10 other plant species, comprehensive evaluation of protein
nutrition was carried out using internationally recognized methods with respect to protein content, chemical score (CS),
essential amino acid index (EAAI), score of ratio coefficient of amino acids (SRCAA), biological value (BV) and nutritional
index (NI). The results indicated that these values for 13 bee pollens were 14.3%-29.0%, 64.4-89.3, 66.9-107, 0, 79.9-91.1,
61.2-104.9 and 11.7-29.3, respectively. The protein content, CS, EAAI, SRCAA, BV and NI for Camellia japonica bee
pollen were 29.0, 83.1, 101.3, 88.8, 98.7 and 29.3, respectively, which were all higher than the average levels of these 13 bee
pollens and indicated the most balanced nutrition.
