Aged Cheese
Cheese ripening, alternatively cheese maturation or affinage, is a process in cheesemaking. It is responsible for the distinct flavour of cheese, and through the modification of "''ripening agents''", determines the features that define many different varieties of cheeses, such as taste, texture, and body. The process is "characterized by a series of complex physical, chemical and microbiological changes" that incorporates the agents of "bacteria and enzymes of the milk, lactic culture, rennet, lipases, added moulds or yeasts, and environmental contaminants". The majority of cheese is ripened, except for fresh cheese. History Cheese ripening was not always the highly industrialised process it is today; in the past, cellars and caves were used to ripen cheeses instead of the current highly regulated process involving machinery and biochemistry. Some cheeses still are made using more historical methods, such as the blue cheese Roquefort, which is required to be ripened in de ...

Refrigeration
The term refrigeration refers to the process of removing heat from an enclosed space or substance for the purpose of lowering the temperature.International Dictionary of Refrigeration, http://dictionary.iifiir.org/search.phpASHRAE Terminology, https://www.ashrae.org/technical-resources/free-resources/ashrae-terminology Refrigeration can be considered an artificial, or human-made, cooling method. Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. This work of energy transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, and air conditioning. Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning ...

Camembert
Camembert (, also , ) is a moist, soft, creamy, surface-ripened cow's milk cheese. It was first made in the late 18th century in Camembert, Normandy, in northwest France. It is sometimes compared in look and taste to brie cheese, albeit with a slightly lower butterfat content than brie's typical 60% and 75% by weight. Production The first camembert was made from unpasteurized milk, and the AOC variety "Camembert de Normandie" (approximately 10% of the production) is required by law to be made only with unpasteurized milk. Many modern cheesemakers, however, use pasteurized milk for reasons of safety, compliance with regulations, or convenience. The cheese is made by inoculating warmed cow milk with mesophilic bacteria, then adding rennet and allowing the mixture to coagulate. The curd is then cut into roughly 1 cm (1/2 inch) cubes, salted, and transferred to low cylindrical camembert molds. The molds are turned every six to twelve hours to allow the whey to drain ev ...

Cheddaring
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. Food ingredients used during manufacture Milk In general, the milk is raw milk (whole or 3.3%). The milk must be "ripened" before adding in the rennet. The term ''ripening'' means allowing the lactic acid bacteria (LAB) to turn lactose into lactic acid, which lowers the pH of the solution, greatly aiding in the coagulation of the milk. This is vital for the production of cheese curds that are later formed into cheddar. Rennet/chymosin/rennin Rennet is an enzyme, originally collected from the stomach of a milk-fed calf (natural rennet). This enzyme is responsible for the coagulation of the milk proteins to produce curds. Cheese produced th ...

Saint-Nectaire
Saint-Nectaire is a French cheese made in the Auvergne region of central France. The cheese has been made in Auvergne since at least the 17th century. History Up until the 17th century, the Saint-Nectaire cheese was farmstead, and mostly made by women. It was also called “rye cheese”, as it was matured on rye. It is known for its creamy and unctuous paste and hazelnut flavour. It was introduced to the court of King Louis XIV by the marshal of France Henri de La Ferté-Senneterre (1600–1681), where the cheese immediately gained the king's favour. By 1768, it was already widely recognized, as Legrand d’Aussy described the cheese in a story about his trip to Auvergne: "If someone wants to treat you to a feast, there is always going to be some Saint-Nectaire". Senneterre was also responsible for the introduction of the cheeses Cantal and Salers. Description This cheese is a non-baked cheese with compressed paste, made from cow's milk, mainly of Holstein and Montbéliarde ...

Stilton Cheese
Stilton is an English cheese, produced in two varieties: Blue, which has '' Penicillium roqueforti'' added to generate a characteristic smell and taste, and White, which does not. Both have been granted the status of a protected designation of origin (PDO) by the European Commission, requiring that only such cheese produced in the three counties of Derbyshire, Leicestershire and Nottinghamshire may be called Stilton. The cheese takes its name from the village of Stilton, now in Cambridgeshire, where it has long been sold. History Frances Pawlett (or Paulet), a cheese maker of Wymondham, Leicestershire, has traditionally been credited with setting up the modern Stilton cheese shape and style in the 1720s, but others have also been named. Early 19th-century research published by William Marshall provides logic and oral history to indicate a continuum between the locally produced cheese of Stilton, and the later development of a high turnover commercial industry importing cheese pr ...

Brie
Brie (; ) is a soft cow's-milk cheese named after Brie, the French region from which it originated (roughly corresponding to the modern ''département'' of Seine-et-Marne). It is pale in color with a slight grayish tinge under a rind of white mould. The rind is typically eaten, with its flavor depending largely upon the ingredients used and its manufacturing environment. It is similar to Camembert, which is native to a different region of France. Brie typically contains between 60% and 75% butterfat, slightly higher than Camembert. "Brie" is a style of cheese, and is not in itself a protected name, although some regional bries are protected. Production Brie may be produced from whole or semi-skimmed milk. The curd is obtained by adding rennet to raw milk and warming it to a maximum temperature of 37 °C (98.6 °F). The cheese is then cast into moulds, sometimes with a traditional perforated ladle called a . The mold is filled with several thin layers of cheese ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ...

Lipolysis
Lipolysis is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and free fatty acids. It is used to mobilize stored energy during fasting or exercise, and usually occurs in fat adipocytes. The most important regulatory hormone in lipolysis is insulin; lipolysis can only occur when insulin action falls to low levels, as occurs during fasting. Other hormones that affect lipolysis include glucagon, epinephrine, norepinephrine, growth hormone, atrial natriuretic peptide, brain natriuretic peptide, and cortisol. Mechanisms In the body, stores of fat are referred to as adipose tissue. In these areas, intracellular triglycerides are stored in cytoplasmic lipid droplets. When lipase enzymes are phosphorylated, they can access lipid droplets and through multiple steps of hydrolysis, breakdown triglycerides into fatty acids and glycerol. Each step of hydrolysis leads to the removal of one fatty acid. The first step and the rate-limiting step of l ...

Proteolysis
Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. Uncatalysed, the hydrolysis of peptide bonds is extremely slow, taking hundreds of years. Proteolysis is typically catalysed by cellular enzymes called proteases, but may also occur by intra-molecular digestion. Proteolysis in organisms serves many purposes; for example, digestive enzymes break down proteins in food to provide amino acids for the organism, while proteolytic processing of a polypeptide chain after its synthesis may be necessary for the production of an active protein. It is also important in the regulation of some physiological and cellular processes including apoptosis, as well as preventing the accumulation of unwanted or misfolded proteins in cells. Consequently, abnormality in the regulation of proteolysis can cause disease. Proteolysis can also be used as an analytical tool for studying proteins in the laboratory, and it may also be used in industry, for example in food proc ...

Glycolysis
Glycolysis is the metabolic pathway that converts glucose () into pyruvate (). The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). Glycolysis is a sequence of ten reactions catalyzed by enzymes. Glycolysis is a metabolic pathway that does not require oxygen (In anaerobic conditions pyruvate is converted to lactic acid). The wide occurrence of glycolysis in other species indicates that it is an ancient metabolic pathway. Indeed, the reactions that make up glycolysis and its parallel pathway, the pentose phosphate pathway, occur in the oxygen-free conditions of the Archean oceans, also in the absence of enzymes, catalyzed by metal. In most organisms, glycolysis occurs in the liquid part of cells, the cytosol. The most common type of glycolysis is the ''Embden–Meyerhof–Parnas (EMP) pathway'', which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol ...

Enzymes
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are Ribozyme, catalytic RNA molecules, called ribozymes. Enzymes' Chemical specificity, specific ...
