Curd
Curd is obtained by coagulating milk in a sequential process called curdling. It can be a final dairy product or the first stage in cheesemaking. The coagulation can be caused by adding rennet or any edible acidic substance such as lemon juice or vinegar, and then allowing it to coagulate. The increased acidity causes the milk proteins ( casein) to tangle into solid masses, or ''curds''. Milk that has been left to sour ( raw milk alone or pasteurized milk with added lactic acid bacteria) will also naturally produce curds, and sour milk cheeses are produced this way. Producing cheese curds is one of the first steps in cheesemaking; the curds are pressed and drained to varying amounts for different styles of cheese and different secondary agents (molds for blue cheeses, etc.) are introduced before the desired aging finishes the cheese. The remaining liquid, which contains only whey proteins, is the whey. In cow's milk, 90 percent of the proteins are caseins. Curds ...

Dahi (Curd)
Curd, also dahi, is a traditional yogurt or fermented milk product, originating from the Indian subcontinent, usually prepared from cow's milk, and sometimes buffalo milk, or goat milk. It is popular throughout the Indian subcontinent. The word ''curd'' is used in Indian English to refer to (naturally probiotic) homemade yogurt, while the term ''yogurt'' refers to the pasteurized commercial variety known as ''heat treated fermented milk''.Codex Alimentarius Yogurt rules FAO Preparation Curd is made by bacterial |
Cheese Curds With Scale Measurement
Cheese is a dairy product produced in wide ranges of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, milk is usually acidified and the enzymes of either 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. Over a thousand types of cheese exist and are produced in various countries. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurized, the butterfat content, the bacteria and mold, the processing, and how long they have been aged. Herbs, spices, or wood smoke may be used as flavoring agents. The yellow to red color of many cheeses is produced by adding an ...

Cheesemaking
Cheesemaking (or caseiculture) is the craft of making cheese. The production of cheese, like many other food preservation processes, allows the nutritional and economic value of a food material, in this case milk, to be preserved in concentrated form. Cheesemaking allows the production of the cheese with diverse flavors and consistencies. History Cheesemaking is documented in Egyptian tomb drawings and in ancient Greek literature. Cheesemaking may have originated from nomadic herdsmen who stored milk in vessels made from sheep's and goats' stomachs. Because their stomach linings contains a mix of lactic acid, bacteria as milk contaminants and rennet, the milk would ferment and coagulate.Kats, Sandor Ellix; Pollan, Michael (2015).

Cottage Cheese
Cottage cheese is a curdled milk product with a mild flavor and a creamy, non-homogeneous, soupy texture. It is made from skimmed milk by draining the cheese, as opposed to pressing it to make cheese curd—retaining some of the whey and keeping the curds loose. An important step in the manufacturing process distinguishing cottage cheese from other fresh cheeses is the adding of a "dressing" to the curd grains, usually cream, which is largely responsible for the taste of the product. Cottage cheese is not aged. Cottage cheese can be low in calories compared to other types of cheese, making it popular among dieters and some health devotees, similar to yogurt. It can be used with a wide variety of foods such as yogurt, fruit, toast, granola, in salads, as a dip, and as a replacement for mayonnaise. It is also known as curds and whey. History Origin A popular story on the origin of cheese was taken from Homer's ''Odyssey'', in which the poet describes how the Cyclops Polyph ...

Curdling
Curdling is the breaking of an emulsion or colloid into large parts of different composition through the physio-chemical processes of flocculation, creaming, and coalescence. Curdling is purposeful in the production of cheese curd and tofu; undesirable in the production of a sauce, cheese fondue or a custard. Method In curdling, the pH of the milk decreases and becomes more acidic. Independently floating casein molecules attract one another, forming "curdles" that float in a translucent whey. At warmer temperatures, the clumping reaction occurs more quickly than at colder temperature. Curdling occurs naturally if cows' milk is left open in a warm environment to air for a few days. Cheese and tofu Milk and soy milk are curdled intentionally to make cheese and tofu by the addition of enzymes (typically rennet), acids (including lemon juice), or various salts ( magnesium chloride, calcium chloride, or gypsum); the resulting curds are then pressed. Egg sauces In hot p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paneer
Paneer (), also known as ponir () is a fresh acid-set cheese common in the Indian subcontinent (Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka) made from full-fat buffalo milk or cow milk. It is a non-aged, non-melting soft cheese made by curdling milk with a fruit- or vegetable-derived acid, such as lemon juice. Etymology The word ''paneer'' entered English from Persian () 'cheese', which comes from Old Iranian. Armenian (), Azerbaijani , Turkish and Turkmen , all derived from Persian , also refer to cheese of any type. History The origin of paneer is debated. Ancient Indian, Afghan-Iranian and Portuguese-Bengali origins have been proposed for paneer. Vedic literature refers to a substance that is interpreted by some authors, such as Sanjeev Kapoor, as a form of paneer. According to Arthur Berriedale Keith, a kind of cheese is "perhaps referred to" in Rigveda 6.48.18. However, Otto Schrader believes that the Rigveda only mentions "a skin of so ...

Curd Cheese
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. Dictionaries sometimes translate it as curd cheese, cottage cheese, farmer cheese or junket. In Germany, quark and cottage cheese are considered to be different types of fresh cheese and quark is often not considered cheese at all, while in Eastern Europe cottage cheese is usually viewed as a type of quark (e.g. Russian for cottage cheese is "зернёный творог" ''zernyony tvorog'', literally "grainy quark"). Quark is similar to French fromage blanc. It is distinct from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yogurt
Yogurt (; , from tr, yoğurt, also spelled yoghurt, yogourt or yoghourt) is a food produced by bacterial fermentation of milk. The bacteria used to make yogurt are known as ''yogurt cultures''. 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 the milk most commonly used to make yogurt. Milk from water buffalo, goats, ewes, mares, camels, and yaks are 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. In addition, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dairy Product
Dairy products or milk products, also known as lacticinia, are food products made from (or containing) milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food items in the Western world such as yogurt, cheese and butter. A facility that produces dairy products is known as a '' dairy''. Dairy products are consumed worldwide to varying degrees (see consumption patterns worldwide). Some people avoid some or all dairy products either because of lactose intolerance, veganism, or other health reasons or beliefs. Production relationship graph Types of dairy product Milk 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 cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whey
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 (also known as sour whey) is a byproduct brought out during the making of acid types of dairy products, such as strained yogurt. Whey proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulins, and proteose peptones. Composition Whey protein is the collection of globular proteins isolated from whey. The protein in cow's milk is 20% whey protein and 80% casein protein, whereas the protein in human milk is 60% whey and 40% casein. The protein fraction in whey constitutes approximately 10% of the total dry solids in whey. This protein is typically a mixture of beta-lactoglobulin (~48-58%), alpha-lactalbumin (~13-19%), bovine serum albumin (~6%)(see also s ...

Rennet
Rennet () is a complex set of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. In addition to chymosin, rennet contains other enzymes, such as pepsin and a lipase. Rennet has traditionally been used to separate milk into solid curds and liquid whey, used in the production of cheeses. Rennet from calves has become less common for this use, to the point that less than 5% of cheese in the United States is made using animal rennet today. Most cheese is now made using chymosin derived from bacterial sources. Molecular action of rennet enzymes One of the main actions of rennet is its protease chymosin cleaving the kappa casein chain. Casein is the main protein of milk. Cleavage causes casein to stick to other cleaved casein molecules and form a network. It can cluster better in the presence of calcium and phosphate. This is why those chemicals are occasionally added to supplement pre-existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
