Cream — Determination of fat content — Acido-butyrometric method
ISO 196660 | IDF 237:2018 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.
This method is applicable to cream having a fat content between 20 % and 50 % inclusive:
- intended for manufacturing butter;
- sweet, unmatured and non-inoculated…
Milk — Determination of fat content — Acido-butyrometric (Gerber method)
ISO 19662 | IDF 238:2018 specifies a method, the acido-butyrometric or "Gerber", for determining the fat content of milk. It is applicable to whole milk and partially skimmed milk.
It is also applicable to milk containing authorized preservatives (potassium dichromate, bronopol).
It does not apply to formalin milk, nor to milks that have undergone a homogenisation treatment.
