黔东黑老虎果营养品质评价

Nutritional Quality Evaluation of Kadsura coccinea Fruit in Eastern Guizhou

  • 摘要: 黑老虎是一种药用价值较高的珍稀植物,本文对黔东黑老虎果进行安全评估和营养成分分析。卫生指标表明黑老虎果中农药残留、重金属和生物毒素指标均符合国家标准。通过与同类浆果巨峰葡萄和红玛瑙石榴的营养成分对比研究,黑老虎果肉中VC含量最高,为159.96 mg/100 g,钙、铁、锌等矿质元素含量丰富,特别是硒元素含量高达3.05 μg/100 g,氨基酸总量为1678.35 mg/100 g。果核中粗多糖、总多酚、总黄酮含量较高,不饱和脂肪酸含量为 87.19%,其中亚油酸、α-亚麻酸相对含量分别为70.78%、7.62%,均高于巨峰葡萄和红玛瑙石榴,是非常理想的优质植物脂肪酸。由此可见,黔东黑老虎果营养丰富,食用安全,本研究为其成为具有发展前景的新食品资源奠定理论基础。

     

    Abstract: Kadsura coccinea was a rare and precious plant with high nutritional and phamaceutical value. In this paper,safety assessment and nutritional analysis were conducted for this fruit. The results showed that,pesticide residues,heavy metals and biotoxins indexes all met the national standards. The nutrient composition of 'Kyoho’ Grape and 'Agate’ pomegranate were compared with this fruit. In Kadsura coccinea fruit pulp,the content of VC was 159.96 mg/100 g. It also contained calcium,iron,zinc and other mineral elements,the content of selenium was as high as 3.05 μg/100 g. The total amount of amino acids was 1678.35 mg/100 g. In Kadsura coccinea fruit seed,the contents of polysaccharides,total polyphenols and flavones were high.The unsaturated fatty acids were accountd for 87.19% of total fatty acids,the relative contents of linoleic acid and linolenic acid were 70.78% and 7.62% respectively,both were higher than 'Kyoho’ Grape and 'Agate’ pomegranate,it would be a very good plant fatty acid. Therefore,the fruit was rich in nutrition and safe to eat,which laid a theoretical foundation for its development as a new food resource.
