标准摘要
[中文适用范围]： ISO 21527 的这一部分规定了一种水平方法，用于计数用于人类消费或喂养动物且水分活度小于或等于 0.95 的产品（干果、蛋糕、果酱、干肉、咸鱼、谷物、麦片及谷类制品、面粉、坚果、香料和调味品等[附件A]），采用25℃±1℃菌落计数技术（参考文献[3]）本部分ISO 21527 的规定不适用于水分活度小于或等于 0.60 的脱水产品（脱水谷物、油质产品、香料、豆科植物、种子、速溶饮料粉末、家畜干产品等），并且不适用允许对霉菌孢子进行计数（参考文献（3）） 真菌头饰的鉴定和食品中霉菌毒素的检查均不在 ISO 21527 本部分的范围内。 ISO 21527 本部分规定的方法不适用于计数嗜盐干真菌（即 Polypaectlurn pisce、Basipetospora halophila），例如可能存在于干鱼中 [外文原描述]： ISO 21527-2:2008 specifies a horizontal method for the enumeration of viable osmophilic yeasts and xerophilic moulds in products intended for human consumption or feeding of animals, having a water activity less than or equal to 0,95 (dry fruits, cakes, jams, dried meat, salted fish, grains, cereals and cereals products, flours, nuts, spices and condiments, etc.), by means of the colony count technique at (25 ± 1) °C. ISO 21527-2:2008 does not apply to dehydrated products with water activity less than or equal to 0,60 (dehydrated cereals, oleaginous, spices, leguminous plants, seeds, powders for instant drinks, dry products for domestic animals, etc.) and does not allow the enumeration of mould spores. Neither the identification of fungal flora nor the examination of foods for mycotoxins lie within the scope of ISO 21527-2:2008. The method specified in ISO 21527-2:2008 is not suitable for enumeration of halophilic xerophilic fungi (i.e. Polypaecilum pisce, Basipetospora halophila ) found in dried fish.
