Ultrafiltered milk

Last updated

Ultrafiltered milk, also known as UF milk, UF skim, or diafiltered milk, is a subclassification of milk protein concentrate that is produced by passing milk under pressure through a thin, porous membrane to separate the components of milk according to size. [1] [2] Specifically, ultrafiltration allows the smaller lactose, water, mineral, and vitamin molecules to pass through the membrane, while the larger protein and fat molecules (key components for making cheese) are retained and concentrated. (Depending on the intended use of the UF milk product, the fat in whole milk may be removed before filtration.) The removal of water and lactose reduces the volume of milk, and thereby lowers its transportation and storage costs.

Ultrafiltration makes cheese manufacturing more efficient. [3] Ultrafiltered milk is also sold directly to consumers under brands like Fairlife and Simply Smart (discontinued producing and selling it May, 2022[ citation needed ]), who tout its higher protein content, lower sugar content, and creamier taste.

Dairy products or milk products, also known as lacticinia, are food products made from milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food around the world such as yogurt, cheese, milk and butter. A facility that produces dairy products is a dairy. Dairy products are consumed worldwide to varying degrees. Some people avoid some or all dairy products because of lactose intolerance, veganism, or other health reasons or beliefs.

Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibodies that strengthen the immune system and thus reduce the risk of many diseases. Milk contains many nutrients, including protein and lactose.

Gouda cheese is a creamy, yellow cow's milk cheese originating from the Netherlands. It is one of the most popular cheeses worldwide. The name is used today as a general term for numerous similar cheeses produced in the traditional Dutch manner.

<span class="mw-page-title-main">Yogurt</span> Food produced by bacterial fermentation of milk

Yogurt is a food produced by bacterial fermentation of milk. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture and characteristic tart flavor. Cow's milk is most commonly used to make yogurt. Milk from water buffalo, goats, ewes, mares, camels, and yaks is also used to produce yogurt. The milk used may be homogenized or not. It may be pasteurized or raw. Each type of milk produces substantially different results.

<span class="mw-page-title-main">Whey</span> Liquid remaining after milk has been curdled and strained

Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey is a byproduct brought out during the making of acid types of dairy products, such as strained yogurt.

Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular (103–106 Da) solutions, especially protein solutions.

<span class="mw-page-title-main">Processed cheese</span> Food product

Processed cheese is a product made from cheese mixed with an emulsifying agent. Additional ingredients, such as vegetable oils, unfermented dairy ingredients, salt, food coloring, or sugar may be included. As a result, many flavors, colors, and textures of processed cheese exist. Processed cheese typically contains around 50 to 60% cheese and 40 to 50% other ingredients.

<span class="mw-page-title-main">Cream cheese</span> Soft, mild-tasting cheese with a high fat content

Cream cheese is a soft, usually mild-tasting fresh cheese made from milk and cream. Cream cheese is not naturally matured and is meant to be consumed fresh, so it differs from other soft cheeses such as Brie and Neufchâtel. It is more comparable in taste, texture, and production methods to Boursin and mascarpone. Stabilizers such as carob bean gum and carrageenan are often added in industrial production.

<span class="mw-page-title-main">Enterocyte</span> Type of intestinal cell

Enterocytes, or intestinal absorptive cells, are simple columnar epithelial cells which line the inner surface of the small and large intestines. A glycocalyx surface coat contains digestive enzymes. Microvilli on the apical surface increase its surface area. This facilitates transport of numerous small molecules into the enterocyte from the intestinal lumen. These include broken down proteins, fats, and sugars, as well as water, electrolytes, vitamins, and bile salts. Enterocytes also have an endocrine role, secreting hormones such as leptin.

<span class="mw-page-title-main">Whey protein</span> Protein supplement

Whey protein is a mixture of proteins isolated from whey, the liquid material created as a by-product of cheese production. The proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin and immunoglobulins. Glycomacropeptide also makes up the third largest component but is not a protein. Whey protein is commonly marketed as a protein supplement, and various health claims have been attributed to it. A review published in 2010 in the European Food Safety Authority Journal concluded that the provided literature did not adequately support the proposed claims.

A milk substitute is any substance that resembles milk and can be used in the same ways as milk. Such substances may be variously known as non-dairy beverage, nut milk, grain milk, legume milk, mock milk and alternative milk.

The manufacture of Cheddar cheese includes the process of cheddaring, which makes this cheese unique. Cheddar cheese is named for the village of Cheddar in Somerset in South West England where it was originally manufactured. The manufacturing of this cheese has since spread around the world and thus the name has become generically known.

Camel milk is milk from female camels. It has supported nomad and pastoral cultures since the domestication of camels millennia ago. Herders may for periods survive solely on the milk when taking the camels on long distances to graze in desert and arid environments, especially in parts of the Middle East, North Africa and the Horn of Africa. The camel dairy farming industry has grown in Australia and the United States, as an environmentally friendly alternative to cow dairy farming using a species well-adapted to arid regions.

<span class="mw-page-title-main">Strained yogurt</span> Yogurt thickened by draining whey

Strained yogurt, Greek yogurt, yogurt cheese, sack yogurt or kerned yogurt is yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland, a similar product named skyr is made.

<span class="mw-page-title-main">Cheese</span> Curdled milk food product

Cheese is a dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk. During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout.

Milk protein concentrate (MPC) is any type of concentrated milk product that contains 40–90% milk protein. The United States officially defines MPC as "any complete milk protein concentrate that is 40 percent or more protein by weight." In addition to ultrafiltered milk products, the MPC classification includes concentrates made through other processes, such as blending nonfat dry milk with highly concentrated proteins, such as casein.

<span class="mw-page-title-main">Whey cheese</span> Dairy product made of whey

Whey cheese is a dairy product made of whey, the by-product of cheesemaking. After the production of most cheeses, about 50% of milk solids remain in the whey, including most of the lactose and lactalbumin. The production of whey cheese allows cheesemakers to use the remaining whey, instead of discarding it as a waste product.

<span class="mw-page-title-main">Sour cream</span> Fermented dairy product

Sour cream is a dairy product obtained by fermenting regular cream with certain kinds of lactic acid bacteria. The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream. Its name comes from the production of lactic acid by bacterial fermentation, which is called souring. Crème fraîche is one type of sour cream with a high fat content and less sour taste.
