太空螺旋藻的生物强化作用
|
摘要
介绍了太空搭载螺旋藻的生物强化作用,它的锌含量是普通螺旋藻粉的80倍,经过太空螺旋藻喂养后的蛋鸡所产蛋的铁含量比普通鸡蛋高出39.1%,表明太空螺旋藻有着较好的生物强化作用。除了微量营养素外,太空螺旋藻的蛋白质、叶绿素、藻蓝蛋白、β-胡萝卜素和亚麻酸的含量分别比普通螺旋藻高出10.8%、28.3%、38.5%、4.8%和16.4%,且螺旋藻鸡蛋的二十二碳六烯酸(DHA)、卵磷脂、β-胡萝卜素和亚麻酸的含量分别比普通鸡蛋高出31.8%、8.3%、305.3%和90.0%,表明它们更具营养价值,对人体健康有更佳的促进作用。
We introduced the biofortification effect of spaceship-carried spirulina, its zinc content was 80 times higher than that of normal spirulina, and the egg layed by spaceship-carried spirulina-feeded hens contained 39.1% higher of iron than normal egg, indicating the superior biofortification effect of spaceship-carried spirulina. In addition to the trace elements, its contents of protein, chlorophyl, phycocyanin, β-carotene, linolenic acid were measured to be 10.8%,28.3%,38.5%,4.8% and 16.4% higher than those of normal spirulina, and the contents of DHA, ovolecithin, β-carotene, linolenic acid contents of spaceship-carried spirulina egg were 31.8%,8.3%,305.3% and 90.0% higher than normal egg, showing that these products had more nutritive value, which could better improve human health.
