⭐ Core Definition: Pasteurized

In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most bacterial spores survive the process.

Pasteurization is named after the French microbiologist Louis Pasteur, whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries for food preservation and food safety.

Pasteurized in the context of Yogurt

Yogurt (UK: /ˈjɒɡərt/; US: /ˈjɡərt/, from Ottoman Turkish: یوغورت, Turkish: yoğurt; also spelled yoghurt, yogourt or yoghourt) 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.

Yogurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus bacteria. Other lactobacilli and bifidobacteria are sometimes added during or after culturing yogurt. Some countries require yogurt to contain a specific amount of colony-forming units (CFU) of bacteria; for example, in China the requirement for the number of lactobacillus bacteria is at least 1 million CFU per milliliter. Some countries also regulate which bacteria can be used: for example, in France, a product can only be labeled as "yaourt" or "yoghourt" if it has been fermented exclusively by Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, a requirement that aligns with the international definition of yogurt in the Codex Alimentarius on fermented milk (CXS 243-2003).

Pasteurized in the context of Flavored milk

Flavored milk is a sweetened dairy drink made with milk, sugar, flavorings, and sometimes food colorings. It may be sold as a pasteurized, refrigerated product, or as an ultra-high-temperature (UHT) treated product not requiring refrigeration. It may also be made in restaurants or homes by mixing flavorings into milk.

In New England, milk blended with flavored syrups such as chocolate or strawberry in a milkshake machine, is commonly called a "milkshake"; in other parts of the United States, a milkshake always includes ice cream or thickeners.

Pasteurized in the context of Caviar

Caviar or caviare is a food consisting of salt-cured roe of the family Acipenseridae. Caviar is considered a delicacy and is eaten as a garnish or spread. Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (beluga, ossetra and sevruga caviars). The term caviar can also describe the roe of other species of sturgeon or other fish such as paddlefish, salmon, steelhead, trout, lumpfish, whitefish, or carp.

The roe can be fresh (non-pasteurized) or pasteurized, which reduces its culinary and economic value.

Pasteurized in the context of Huangjiu

Huangjiu (Chinese: 黃酒; lit. 'yellow wine') is a type of Chinese rice wine (mijiu) most popular in the Jiangnan area. Huangjiu is brewed by mixing steamed grains including rice, glutinous rice or millet with as starter culture, followed by saccharification and fermentation at around 13–18 °C (55–64 °F) for fortnights. Its alcohol content is typically 8% to 20%.

Huangjiu is usually pasteurized, aged, and filtered before its final bottling for sale to consumers. The maturation process can be complicated but important for the development of the layers of flavors and fragrance. A few brands of premium grade huangjiu could have been aged for up to 20 years. As huangjiu's name suggests, its typical color is typically light yellow and orange, but it can in fact range from clear to brown. Many famous huangjiu brands promote the quality of water used in brewing in their advertising, and some consider it to be the most important ingredient.

Pasteurized in the context of Apple cider

Apple cider (also called sweet cider, soft cider, or simply cider) is the name used in the United States and Canada for an unfiltered, unsweetened, non-alcoholic beverage made from apples. Though typically referred to simply as "cider" in North America, it is not to be confused with the alcoholic beverage known as cider in the rest of the world, which is called "hard cider" in the US. Outside of the United States and Canada, it is commonly referred to as cloudy apple juice to distinguish it from clearer, filtered apple juice and hard cider.

Fresh liquid cider is extracted from the whole apple, including the apple core, trimmings from apples, and oddly sized or shaped “imperfect” apples, or apple culls. Fresh cider is opaque due to fine apple particles in suspension and generally tangier than commercially cooked and filtered apple juice, but this depends somewhat on the variety of apples used. Cider is sometimes pasteurized or exposed to UV light to kill bacteria and extend its shelf life, but traditional raw untreated cider is still common. Some companies have begun adding preservatives and boiling cider, so that it can be shelf stable and stored without refrigeration. In either form, apple cider is seasonally produced in autumn. It is traditionally served on Halloween, Thanksgiving, Christmas, and New Year's Eve, sometimes heated and mulled.

Pasteurized in the context of Buttermilk

Buttermilk is a dairy drink made by adding lactic acid bacteria to milk to produce a fermented dairy drink. Traditionally, it was made from the nearly fat-free milk remaining after churning butter from cream, which was cultured with natural bacteria prior to and during churning, giving a slight sour taste to the buttermilk. However, with the ubiquity of refrigeration in industrialized countries, butter in those areas is typically made from uncultured or "sweet" cream. Therefore, most modern buttermilk is specifically produced by inoculating fresh, pasteurized milk, and is available in different levels of fat content.

Buttermilk is consumed as a beverage and used in cooking. Drinking buttermilk remains common in warmer climates where unrefrigerated milk sours quickly, as the fermentation prevents further spoilage. In making soda bread, the acid in fermented buttermilk reacts with the leavening agent, sodium bicarbonate, to produce carbon dioxide. Buttermilk is used in marination, especially for chicken and pork.
