Application

Clarifying reagent for dairy products can be used in many chemical and enzymatic colorimetric measurements for estimating the quality of milk and dairy products. Clarifying reagent for dairy products renders opaque milk and dairy product samples transparent, which allows direct photometric measurements of the reaction mixtures. Clarifying reagent for dairy products has been used to optimize, validate and compare three methods of determining lipase activity in skim and whole milk.

Difficulties with the analysis of opaque milk and dairy products can be resolved by rendering the sample transparent. This allows direct photometric measurements of the reaction mixtures, and all sample pre-treatment steps become unnecessary. For this, several reagents have been

Three methods of determining lipase activity were optimized, validated, and compared using skim and whole milk. A chromogenic ester (p-nitrophenyl caprylate) was used in all to quantify the enzyme activity through the release of p-nitrophenol. It was measured colorimetrically (method
