As mentioned earlier, triglycerides are the predominant fat found in milk. The structure of the fats in butter is very important as they will impact the melting and softness of the butter. The fat in milk is about 70% saturated (solid at room temperature single bonds in the fatty acid structure) and 30% unsaturated (liquid at room temperature double bond(s) in the fatty acid structure).

Intact triglycerides do not have much flavor or taste, but enzymes like lipases can break down triglycerides into free fatty acids, which are more volatile and interact with our olfactory glands to give strong flavors, which, again are not desired in buttermaking. Lipolysis, or the breakdown of triglycerides with the release of fatty acids, produces flavors, which in the case of buttermaking, may not be desired. This is why it is important to preserve cream quality for buttermaking. This introduces oxygen causing oxidization or allows enzymes to get into the globules causing off flavors to develop (hydrolytic rancidity). Excessive pumping or handling of milk can breakdown and damage the layers surrounding the milkfat globules. Milkfat globules have three layers that protect fat triglycerides - these layers protect the quality of the fat. T he fat in milk is found in the form of milkfat globules, which range in size from 0.1-20 microns. The amounts and structure of these lipids serve important roles in the emulsification effects in buttermaking, which impact melting and spreadability. The rest of the fat content in milk is divided up of mono & di-glycerides (about 0.5%), cholesterol (about 0.3%) and phospholipids (about 0.6%). Triglycerides make up about 97-98% of the fat found in milk. The lipids or fat and types of fat in milk are important to understanding the science behind buttermaking. Therefore, quality metrics associated with these reactions should be included during cream testing (see table below). The latter is usually due to the breakdown of triglycerides by lipases (enzymes that breakdown fats), resulting in baby vomit or soapy-like flavors. The former involves the reaction of fat with oxygen resulting in cardboard-like off flavors. Two main reactions that can occur to fat are lipid oxidation and hydrolytic rancidity.

Since buttermaking by its very nature has the goal of concentrating the fat in cream, the quality of the fat/lipid component of the starting cream is critical. Other important values to monitor include standard plate count, coliform count, etc. If the pH of the cream is too low (below pH 6.4), it is indicative of the presence of undesired bacteria. If this value is too high or too low, it will negatively impact yield efficiency. Milkfat content should be in the range of 35-40%. Some important measures for cream are milkfat content and pH. If you do not have quality cream, you can’t make quality butter. The most important aspect of buttermaking is cream quality. While butter is a simple product made from only a couple of ingredients, the physical changes that take place during butter production are more complex. The typical composition of butter is: 80-82% fat, 16-17.5% water, 1.5% salt, and 1% milk solids (vitamins, minerals, and lactose). An Act of Congress that was approved Madefines butter as being “made exclusively from milk or cream or both, with or without common salt and with or without additional coloring matter and contains not less than 80% by weight of milkfat, all tolerances allowed for.” In addition to salted and unsalted butter, there are two main types of butter – sweet cream butter and cultured butter. citizens consumed 6.2 pounds per person – a more than 26% increase from 2010.īutter, like many dairy products, is made from only a couple of ingredients.
