How milk is made depends on a number of different technologies - all designed to make the process more efficient. Cows are milked using vacuum cups which are attached to the cow's teats. Within 48 hours, milk is taken in tankers to a milk factory where it's pasteurised and homogenised.

Within 48 hours, milk is taken in tankers to a milk factory where it's pasteurised and homogenised. This also extends the shelf life. Homogenisation Milk is put under pressure through fine nozzles, which evenly disperses fat globules. This stops the cream separating and rising to the top, allowing a more consistent texture and taste. Some manufacturers produce unhomogenised milk for people who prefer the cream to separate and rise to the top of the bottle.
Today's farm technology, cattle management and factory methods allow for greater consistency of milk, and milk composition can be adjusted for year-round consistency. Milk composition is standardised so elements like fat content are made consistent no matter the season or breed of cow the milk comes from. These standards are consistent with international standards — milk consumed in nearly all developed countries will have very similar standards. The Code allows manufacturers to add or withdraw milk components to standardise the composition of milk sourced from dairy farms, as required, to produce nutritionally consistent and safe products.
Under the Code, the standard for packaged full-fat milk requires that it contain at least 3. Centrifugal separation. This removes some or all of the cream to make reduced-fat, low-fat or skim milk. Skim milk solids can be added back to improve the test and texture, and increase nutrients like protein and calcium.
Water and lactose the sugar in milk pass through, leaving behind a very protein and calcium-rich product. The fat content can be adjusted to suit consumer preference. Reverse osmosis. This is very similar to ultrafiltration, but the membrane holds back most of the milk solids and only lets water pass through.
Lactose remains in the product. There is no impact on flavour. Ultra osmosis. This is a combination of ultrafiltration and reverse osmosis, but it holds back milk solids and allows both water and salt to pass through.
Spray drying. This removes water from milk in order to make powdered milk products. In order to standardise milk year-round, some manufacturers use a process called ultrafiltration where a membrane filter separates certain elements from milk just like in the descriptions above. Milk is passed through a very fine filter, and the lactose milk sugar , vitamins and minerals that filter through are referred to as "permeate". Permeate is a technical term which applies to all membrane filtration processes used across food production and other industries.
For example, when producing apple juice the fruit is put through a similar filtration process where permeate is the clear juice we end up buying and consuming. In milk processing, the word "permeate" does not refer to anything added which was not already part of milk. That filter helps milk producers make milk with consistent properties, which helps it conform to the Food Standards Australia New Zealand Food Standards Code.

milk and milk processing
Campbell, Robert T. Marshall January A productive dairy industry is vital to providing safe, high-quality milk that fulfills the nutritional needs of people of all ages around the world. Dairy Production and Processing offers not only a fundamental understanding of dairy animals, dairy products, and the production aspects of each, but also a wealth of applied information on the scope of the current milk and milk products industry. The application of basic sciences and technologies throughout the text will serve students well not only as they learn the first principles of dairy science, but also as a professional reference in their careers.
Dairy products or milk products are a type of food produced from or containing the milk of mammals , most commonly cattle , water buffaloes , goats , sheep , and camels. Dairy products include food items such as yogurt , cheese and butter. Milk is produced after optional homogenization or pasteurization , in several grades after standardization of the fat level, and possible addition of the bacteria Streptococcus lactis and Leuconostoc citrovorum. Milk can be broken down into several different categories based on type of product produced, including cream, butter, cheese, infant formula, and yogurt. Milk varies in fat content. Skim milk is milk with zero fat, while whole milk products contain fat.

For questions about the Dairy Program, call or explore this web page. Sarah Coburn for more information. While the FDA provides approval of state dairy programs, individual states that desire to have a commercial dairy industry are expected to maintain regulatory dairy programs in accordance with the PMO — there is no federal dairy program in place to support states without one. Without an FDA-approved state program, commercial dairy operations would be unable to sell products to institutions that receive federal funds to subsidize meal programs military, schools, prisons, etc. At this time, all 50 states have a state dairy program.
