This group covers natural butter, whey butter and recombined butter (fresh, salted or rancid, including canned butter). Butter must be derived exclusively from milk and must have a milkfat content of 80 % or more but not more than 95 % by weight, a maximum milk solids-not-fat content of 2 % by weight and a maximum water content of 16 % by weight. Butter contains no added emulsifiers, but may contain sodium chloride, food colours, neutralising salts and
cultures of harmless lactic-acid-producing bacteria. (See Note 3 (a) to this Chapter).
