摘要
分析了紫球藻的主要营养成分。结果表明,紫球藻蛋白质含量为32.1%,氨基酸含量为29.54%(色氨酸未测),赖氨酸为第1限制性氨基酸,氨基酸评分87;碳水化合物39.4%,总膳食纤维21.7%;灰分17.6%,水分7.8%,每千克干藻粉中Ca、Mg、K和Zn含量分别为20g、4.1g、9.5g和92mg。每千克干藻粉中含β-胡萝卜素240mg、VB618mg。有毒重金属Pb、As和Hg含量符合有关规定。
Nutritional compositions were analysed for the red microalga Porphyridium cruentum. The results showed that the biomass contented 39.4% carbohydrates,21.7% crude fibre;32.1% protein, 29.54% amino acids, the score of amino acid is 87 and the first limited amino acid is Lysine;17.6% ash, 7.8% moisture. The minerals contented in 1000g dry biomass were:20000 mg Ca,4100 mg Mg,92 mg Zn, 9500 mg K. The vitamins contented in 1000g dry biomass were: 240 mg β-carotene and 18 mg V_(B_6). Toxic heavy metals contents were negligible.
