适用范围：This part of ISO 21527 specifies a horizontal method for the enumeration of viable yeasts and moulds inproducts intended for human consumption or feeding of animals that have a water activity greater than 0,95[eggs, meat, dairy products (except milk powder), fruits, vegetables, fresh pastes, etc], by means of thecolony count technique at 25 ℃ ±1 ℃ (References [1], [2]).This part of ISO 21527 does not allow the enumeration of mould spores. Neither the identification of fungalflora nor the examination of foods for mycotoxins lie within the scope of this part of ISO 21527 The methodspecified in this part of ISO21527 is not suitable for enumeration of heat resistant fungi, such asByssochlamys fulva or Byssochlamys nivea, in canned or bottled frud and vegetables
