In the United States, Grade A milk, also called fluid grade milk, refers to milk produced under sufficiently sanitary conditions to qualify for fluid (beverage) consumption. Only Grade A milk is regulated under federal milk marketing orders. Grade B milk (also referred to as manufacturing grade milk) does not meet fluid grade standards and can only be used in cheese, butter and nonfat dry milk. More than 90% of all milk produced nationally is Grade A, and much of the Grade A milk supply is used in manufactured dairy products.
Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications. The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. It is typically produced as a free-flowing, off-white powder.
A dairy is a place where milk is stored and where butter, cheese and other dairy products are made, or a place where those products are sold. It may be a room, a building or a larger establishment. In the United States, the word may also describe a dairy farm or the part of a mixed farm dedicated to milk for human consumption, whether from cows, buffaloes, goats, sheep, horses or camels.
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
A hydrometer or lactometer is an instrument used for measuring density or relative density of liquids based on the concept of buoyancy. They are typically calibrated and graduated with one or more scales such as specific gravity.
Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH)2. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (Ksp = 5.61×10−12). Magnesium hydroxide is a common component of antacids, such as milk of magnesia.
Buttermilk is a fermented dairy drink. Traditionally, it was the liquid left behind after churning butter out of cultured cream. As most modern butter in western countries is not made with cultured cream but uncultured sweet cream, most modern buttermilk in western countries is cultured separately. It is common in warm climates where unrefrigerated milk sours quickly.
Parmesan is an Italian hard, granular cheese produced from cows' milk and aged at least 12 months.
Soy milk also known as soya milk or soymilk, is a plant-based drink produced by soaking and grinding soybeans, boiling the mixture, and filtering out remaining particulates. It is a stable emulsion of oil, water, and protein. Its original form is an intermediate product of the manufacture of tofu. Originating in China, it became a common beverage in Europe and North America in the latter half of the 20th century, especially as production techniques were developed to give it a taste and consistency more closely resembling that of dairy milk. Soy milk may be used as a substitute for dairy milk by individuals who are vegan or are lactose intolerant.
Cream cheese is a soft, usually mild-tasting fresh cheese made from milk and cream. Stabilizers such as carob bean gum and carrageenan are often added in industrial production.
Powdered milk, also called milk powder, dried milk, or dry milk, is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. Another purpose is to reduce its bulk for the economy of transportation. Powdered milk and dairy products include such items as dry whole milk, nonfat (skimmed) dry milk, dry buttermilk, dry whey products and dry dairy blends. Many exported dairy products conform to standards laid out in Codex Alimentarius.
Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea. The gellan-producing bacterium was discovered and isolated by the former Kelco Division of Merck & Company, Inc. in 1978 from the lily plant tissue from a natural pond in Pennsylvania. It was initially identified as a substitute gelling agent at significantly lower use level to replace agar in solid culture media for the growth of various microorganisms. Its initial commercial product with the trademark as Gelrite gellan gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical bacteriological media.
Storage tanks are containers that hold liquids, compressed gases or mediums used for the short- or long-term storage of heat or cold. The term can be used for reservoirs, and for manufactured containers. The usage of the word tank for reservoirs is uncommon in American English but is moderately common in British English. In other countries, the term tends to refer only to artificial containers.
Tobin Arms was a firearms company started in 1905 in Norwich, Connecticut, United States. It produced side-by-side and double-barrel shotguns in various grades. The company moved to Woodstock, Ontario, Canada in 1909 or 1910. It then made shotguns until 1925 before shutting down.
Grinding is a type of abrasive machining process which uses a grinding wheel as cutting tool.
The Bender Machine Works in Hayward, Wisconsin, is a dairy equipment manufacturer that played a major role in the history of the dairy farming business in the United States from the 1950s to the 1980s, producing milk pipeline and milk transfer cart components, and washing/vacuum-releasing equipment.
Classified pricing is the pricing system of federal milk marketing orders, under which milk processors pay into a pool for fluid grade milk. The price that processors have to pay into the pool is based on how the milk ultimately is used. Milk used for fluid (Class I) consumption generally receives the highest price and lower minimum prices are paid for the three classes of milk used for manufactured dairy products: Class II, Class III (cheese), and Class IV.
Quark or quarg is a type of fresh dairy product made from milk. The milk is soured, usually by adding lactic acid bacteria cultures, and strained once the desired curdling is achieved. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added. It is traditional in the cuisines of Baltic, Germanic and Slavic-speaking countries as well as amongst Ashkenazi Jews and various Turkic peoples.
Sour cream or soured 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.
Watercolor paper or watercolour paper is paper or substrate onto which an artist applies watercolor paints, pigments or dyes. We generally no longer use stone or tomb walls as a substrate. There are currently many types of watercolour papers available that are manufactured for the use of watercolors. Watercolor paper can be made of wood pulp exclusively, or mixed with cotton fibers. Pure cotton watercolor paper is also used by artists, though it typically costs more than pulp based paper. It is also available as an acid-free medium to help its preservation.
