摘要
为系统分析评价不同品种木奶果果实的营养价值,以红皮木奶果、黄皮木奶果、绿皮木奶果果实为材料,运用常规营养成分检测方法对3种果实中果皮、种子、果肉的净质量及有机物、水分、灰分含量进行测定,对果汁中可溶性蛋白质等营养成分进行测定与分析.结果表明:3个品种的木奶果果汁可溶性蛋白质的含量分别为0.032 1、0.077 8和0.281 mg·g-1(黄皮木奶果＜绿皮木奶果＜红皮木奶果).可溶性糖含量分别为61.462 5、94.212 5和125.545 8 μg(红皮木奶果＜绿皮木奶果＜黄皮木奶果),三者差异极显著.可溶性淀粉含量分别为0.027 1％、0.031 8％、0.054 2％(黄皮木奶果＜绿皮木奶果＜红皮木奶果).因此,绿皮木奶果单个果实质量最大,出汁率最高,含有较高的可溶性蛋白、可溶性糖和可溶性淀粉,甜度高,口感酸,风味足;黄皮木奶果与绿皮木奶果相似,但出汁率较低;红皮木奶果的出汁率、可食率和可溶性糖偏低,但其可溶性淀粉含量偏高,其果肉的可溶性蛋白更高.
Abstract
In order to systematically analyze and evaluate the nutritional value of Baccaurea ramiflora fruit of differ-ent varieties,taking the fruits of Red Baccaurea ramiflora,Yellow Baccaurea ramiflora and Green Baccaurea ram-iflora as materials,net weight,organic matter,moisture and ash content of peel,seed and pulp of three kinds of fruits were determined by conventional nutrient detection methods,and the soluble protein and other nutrients in fruit juice were determined and analyzed.The results showed as follows:the contents of soluble protein were 0.032 1 mg·g-1,0.077 8 mg·g-1 and 0.281 mg·g-1 respectively in the juice of the three cultivars(Yellow Baccaurea ramiflora＜Green Baccaurea ramiflora＜Red Baccaurea ramiflora);the contents of soluble sugar were 61.462 5μg,94.212 5 μg and 125.545 8 μg(Red Baccaurea ramiflora＜ Green Baccaurea ramiflora＜Yellow Baccaurea rami-flora),and there were significant differences among them;the content of soluble starch were 0.027 1％,0.031 8％and 0.054 2％(Yellow Baccaurea ramiflora＜Green Baccaurea ramiflora＜Red Baccaurea ramiflora).There-fore,the single fruit weight and juice yield of the Green Baccaurea ramiflora were the highest,which contained high soluble protein,soluble sugar and soluble starch,high sweetness,sour taste and full flavor.The fruit of Yellow Bac-caurea ramiflora was similar to Green Baccaurea ramiflora,but the juice yield was lower.The juice yield,edible rate and soluble sugar of Red Baccaurea ramiflora were lower,but the soluble starch content was higher,and the soluble protein in the pulp was much higher.
