Together with water, protein, fibre and sodium content, fat content is one of the five key parameters used in assessing food quality. The traditional standard reference method for fat analysis is based on either weight or volumetric determination. Cheese analogues produced by using plant proteins and vegetable oils might show poor sensory and functional characteristics due to the low protein flexibility. In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions.The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

Feed standard AAFCO Fat labeled range: 5.939 - 6.814 % In order to determine the total fat in feed a direct extraction with solvents is not efficient because a part of lipids is chemically bonded with other components. Principle: Soxhlet extraction has been used widely for extracting valuable bioactive compounds from various natural sources. 0.52 to 6.89% for fat, 0.39 to 1.55% for moisture, and 0.54 to 5.23% for protein. T raditional chemical analysis methods involve lengthy processes and may take several hours to generate results, which in many food production industries hinder real-time production and product-quality decisions.
