以人工培养的地木耳(Nostoc commune Vauch.)为材料,测定其生化组成,并对培养的地木耳显微结构进行观察.结果表明:地木耳表层藻丝较中央藻丝排列更加紧密,中央藻丝有或无单独胶鞘包裹;人工培养的地木耳含16种氨基酸,蛋白质含量为17.46%;脂肪含量为0.53%,低于野生地术耳中脂肪的含量;维生素含量较低;矿质元素含量远高于野生地木耳的含量;而砷、铅、汞、镉4种重金属元素含量较低,符合国家食品卫生标准.

Cultivated Nostoc commune Vauch.was used as the raw material to determine its biochemical composition and structure.Results indicated that surface trichomes of cultivated N. commune exhibited more tight arrangement than that of the interiors.Meanwhile,some trichomcs in the interior were enveloped by sheath.Cultivated N.commune contained 17.46% protein that was composed of 16 kinds of amino acids and 0.53% fatty acid.Compared to wild N.commune,lower fatty acid and vitamin contents were determined in cultivated N.commune,which,however,was rich in mineral elements and exhibited contents of heavy metals such as As,Pb,Hg and Cd that were much lower than the maximum threshold stipulated in the Chinese national food hygiene standards.
