Butter Testing Services

Butter testing service has Direct and indirect methods that can be used to calculate the fat content of butter. Indirect (fat-by-difference) methods calculate the fat content by subtracting the non-fat portion of the butter from 100 percent. Direct methods measure fat directly. To determine fat by difference, essentially two distinct groups of approaches have been used. One category of approaches is based on the notion of physically separating the entire non-fat part from the fat and then volumetrically determining the total non-fat portion. The other group of procedures, known as gravimetric methods, determines the moisture and solids-not-fat (SNF) components of the butter independently. A variety of test approaches have been published for the direct assessment of fat in butter. Refractometric and weighing methods, saponification processes, and filtering are examples of these.
