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. Data from the USDA Economic Research Service shows that in 2019, U.S.
