摘要

研究了美洲柏树(Persea americana)、毛竹(Dacryodes edulis)和Canarium scheinfurthi果实的营养成分和化学成分,并对其种子油进行了部分表征,以确定其营养价值。分析了果肉的化学(近似)组成、氨基酸、维生素、植物化学和抗营养成分。从果实种子中提取油脂,并按标准方案测定籽油的理化性质。结果表明,抗营养素含量低的品种果肉中宏量营养素和微量营养素含量差异显著(p < 0.05)。各品种间必需氨基酸含量均较高且差异显著(p < 0.05)。各品种的氨基酸含量以谷氨酸最高,其次是天冬氨酸,蛋氨酸和半胱氨酸含量较低。结果还显示,必需氨基酸得分较高,异亮氨酸和总芳香氨基酸得分均在100%以上。果油的理化性质表明,这些油是可食用的(低酸值),由于它们的过氧化物、碘和皂化值低,可能具有工业潜力。总的来说,结果表明梨营养丰富,可以用于饮食和工业用途。

Nutritional Assessment of Pulps and Partial Characterization of Seed Oils from Varieties of Pear Fruits
The nutrients and chemical contents of Persea americana, Dacryodes edulis, and Canarium scheinfurthi fruits and partial characterization of their seed oils were carried out to ascertain their nutritional benefits. The fruit pulps were analyzed for chemical (proximate) composition, amino acids profile, vitamins, and phytochemical and anti-nutritional compositions. Oils were extracted from the fruit seeds and the physico-chemical properties of the seed oils were determined according to the standard protocols. The results showed that the fruit pulps contained an abundance of macro- and micro-nutrients which varied significantly (p < 0.05) among the varieties with low anti-nutrients. The essential amino acid contents were high and varied significantly (p < 0.05) among the varieties. Glutamic acid, followed by aspartic acid had the highest concentration of the amino acids, while the concentrations of methionine and cysteine were low in all the varieties. The results also revealed high essential amino acids score values, above 100% for isoleucine and total aromatic amino acids. The physicochemical properties of the fruit oils showed that the oils were edible (low acid value) and may have industrial potential due to their low peroxide, iodine, and saponification values. Overall, the results showed that the pears are nutritionally rich and could serve dietetic and industrial purposes.
