An Overview of Determination of Milk Fat: Development, Quality Control Measures, and Application

Abstract

Milk fat content is an important indicator of milk quality because of nutritional and technological aspects of dairying. In this sense the milk fat determination is important practice procedure. The work goal was to do an effective overview and comparison of reference and routine methods of fat determination during their development. Nowadays, there exist a number of methods for determining milk fat content. Reference methods require accurate analysis in compliance with the International Standard ISO, whereas routine methods perform analysis using routine instrumental techniques for faster and cheaper results with acceptable accuracy. Quality control measures have a significant role for result determination reliability and they include internal quality controls, external quality controls, precision of evaluation, and blank samples. In conclusion, due to continuous development and improvement, routine methods will be used more often.

“…Therefore, it is extremely important that the ration for dairy ruminants is balanced in terms of the supply of digestible proteins and energy. (Hanuš et al, 2018;Linn, 1988). P+ dojnic v problémovém stádě 26,5 %.…”

“…Z referenčních lze jmenovat například Kjeldahlovu metodu pro stanovení obsahu bílkovin, Gerberovu metodu pro stanovení obsahu tuku nebo vysokoúčinnou kapalinovou chromatografii pro stanovování minoritních složek mléka nebo cizorodých látek aj. (Karageorgou et al, 2018;Kala et al, 2018Kala et al, , 2019Samková et al, 2020).…”

“…Одним з основних факторів якості молока є склад, який впливає на властивості молока. Молочний жир відіграє важливу роль не лише в поживних, фізичних і хімічних властивостях молока, а й у його купівлі (Kala et. al., 2018).…”

“…In addition, chloroform and methanol are also valid elution solvents [86]. Total MPLs can be measured using the IDF molybdate assay [87], Fourier transform infrared spectroscopy [88], or a fluorescence assay on cleaved choline group [89]. Both nuclear magnetic resonance of 31 P and chromatography can quantify MPLs and their subclasses [90,91].…”
