This document specifies an acidobutyrometric method for determining the fat content of cream. The reference method remains the gravimetric method (by ammoniacal ether extraction) described in ISO 2450 | IDF 16.<\/p>\n
This method is applicable to cream having a fat content between 20 % and 50 % inclusive:<\/p>\n
intended for manufacturing butter;<\/p>\n<\/li>\n
sweet, unmatured and non-inoculated;<\/p>\n<\/li>\n
raw or having undergone a heat treatment;<\/p>\n<\/li>\n
non-homogenized;<\/p>\n<\/li>\n
with or without preservatives (2-bromo-2-nitropropane, 1,3 diol or bronopol).<\/p>\n<\/li>\n<\/ul>\n
