Whey Cheese
Whey is the liquid remaining after milk has been curdling, 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 cheese, cheddar or Swiss-type cheeses, 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 Beta-lactoglobulin, β-lactoglobulin (48%–58%), Α-Lactalbumin, α-lactalbumin (13%–19%), Glycomacropeptide (12%–20%), bovine serum albumin, heavy and light chain immunoglobulins and several minor whey proteins. Composition Sweet whey and acid whey are similar in gross nutritional analysis. By mass both contain 93% water, about 0.8% protein, and about 5.1% carbohydrates. Sweet whey contains about 0.4% fat while sour whey contains about 0.1% fat. The carbohydrates are mainly lactose. The pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soured Milk Whey
Souring is a food preparation technique that causes a physical and chemical change in food by exposing it to an acid. This acid can be added explicitly (e.g., vinegar, lemon juice, lime juice, etc.), or can be produced within the food itself by a microbe, such as ''Lactobacillus''. Souring is similar to pickling or Fermentation in food processing, fermentation, but souring typically occurs in minutes or hours, while pickling and fermentation can take a much longer amount of time. Examples Dairy products produced by souring include: Clabber (food), Clabber, Cheese, ''Crème fraîche'', Cultured buttermilk, Curd, ''Filmjölk'', ''Kefir'', ''Paneer'', Smetana (dairy product), ''Smetana'', Soured milk, Sour cream, and Yogurt. Grain products include: Idli, Sourdough, and Sour mash. Others foods produced by souring include: ''Ceviche'', ''Kinilaw'', and Key lime pie.

Acid
An acid is a molecule or ion capable of either donating a proton (i.e. Hydron, hydrogen cation, H+), known as a Brønsted–Lowry acid–base theory, Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acid–base theory, Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Acid–base reaction#Arrhenius theory, Arrhenius acids. Johannes Nicolaus Brønsted, Brønsted and Martin Lowry, Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and ...

Glycomacropeptide
Glycomacropeptide (GMP) is a glycosylated peptide formed during renneting as a fragment of sweet whey. Acid whey from yogurt or curdling cheese without the use of rennet does not contain GMP. The unglycosylated form is known as caseinomacropeptide or CMP. Both forms exist in roughly similar amounts in whey. Together GMP and CMP make up 20-25% of whey protein. This makes them the third largest fraction of whey protein isolate, after alpha-lactalbumin and beta-lactoglobulin. GMP is formed when the casein micelle that encapsulates milk protein is cleaved by the enzyme chymosin. The 64 terminal peptides of Kappa-casein are removed by the enzyme to create GMP. The remaining peptides form para-kappa-casein.{{cite journal , last1=Córdova , first1=Dávalos , title=Glycomacropeptide Bioactivity and Health: A Review Highlighting Action Mechanisms and Signaling Pathways , journal=Nutrients , date=March 11, 2019 , volume=11 , issue=3 , page=598 , doi=10.3390/nu11030598 , pmid=30870995 , p ...

Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid ...

Compound Feed
Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word ''feed'' more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like Spent grain, spent grain from beer brewing. Animal wellbeing is highly dependent on feed that reflects a well balanced nutrition. Some modern agricultural practices, such as fattening cows on grains or in feed lots, have detrimental effects on the environment and animals. For example, increased corn or other grain in feed for cows, makes their microbiomes more acidic weakening their immune systems and making cows a more likely vector for E.coli, ''E. coli'', while other feeding practices ...

Brunost
' () is a common Norwegian name for (; ; ; ; ''/''), a family of soft cheese-related foods made with whey, milk, and/or cream. The characteristic brown color and sweet taste result from milk sugars being caramelized after boiling. The term is often used to refer to or (' Gudbrandsdal cheese'), which are the most popular varieties. is primarily produced in Norway and is popular there, and has spread to South Korea. It is regarded as one of Norway's most iconic foodstuffs, and is considered an important part of the country's gastronomical and cultural identity and heritage. History Boiling down whey 10:1 to create a brown, cheesy spread (such as the Norwegian and Swedish ) has been common in the Scandinavian countries for at least 2,500 years. An archeological find from September 2016 in central Jutland has determined that a cheese residue on pottery from circa 650 B.C.E. is a type of cheese, potentially similar to .

Ricotta
Ricotta () is an Italian whey cheese made from sheep, cow, goat, or Italian water buffalo milk whey left over from the production of other cheeses. Like other whey cheeses, it is made by coagulating the proteins that remain after the casein has been used to make cheese, notably albumin and globulin. Ricotta () protein can be harvested if the whey is first allowed to become more acidic by additional fermentation (by letting it sit for 12–24 hours at room temperature). Then the acidified whey is heated to near boiling. The combination of low pH and high temperature denatures the protein and causes it to flocculate, forming a fine curd. Once cooled, it is separated by passing the liquid through a fine cloth, leaving the curd behind. Ricotta curds are creamy white in appearance, and slightly sweet in taste. The fat content varies depending on the milk used. In this form, it is somewhat similar in texture to some fresh cheese variants, though considerably lighter. It is hi ...

Denaturation (biochemistry)
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation, radiation, or heat. If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Protein denaturation is also a consequence of cell death. Denatured proteins can exhibit a wide range of characteristics, from conformational change and loss of solubility or dissociation of cofactors to aggregation due to the exposure of hydrophobic groups. The loss of solubility as a result of denaturation is called ''coagulation''. Denatured proteins, e.g., metalloenzymes, lose their 3D structure or metal cofactor, and therefore, cannot function. Proper protein folding is key to whether a globular or memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spray Drying
Spray drying is a method of forming a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals, or materials which may require extremely consistent, fine particle size. Air is most commonly used as the heated drying medium; however, nitrogen may be used if the liquid is flammable (such as ethanol) or if the product is oxygen-sensitive. All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disk and single-fluid high pressure swirl nozzles. Atomizer wheels are known to provide broader particle size distribution, but both methods allow for consistent distribution of particle size. Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process requirements, drop sizes from 10 to 500 μm can be achieved with t ...
