Torula (Cyberlindnera jadinii) is a species of yeast.
Torula, in its inactive form (usually labeled as torula yeast), is widely used as a flavoring in processed foods and pet foods. It is often grown on wood liquor, a byproduct of paper production, which is rich in wood sugars (xylose). [3] It is pasteurized and spray-dried to produce a fine, light grayish-brown powder with a slightly yeasty odor and gentle, slightly meaty taste.
Cyberlindnera jadinii (which in these contexts is often still labelled with its synonym Candida utilis) can be used, in a blend of various other yeasts, as secondary cheese starter culture "... to inoculate pasteurised milk, which mimic the natural yeast flora of raw milk and improve cheese flavour. Other functions of the added yeast organisms are the neutralisation of the curd (lactate degradation) and galactose consumption." [4]
Like the flavor enhancer monosodium glutamate (MSG), torula is rich in glutamic acid. Therefore, it has become a popular replacement among manufacturers wishing to eliminate MSG or hide flavor enhancer usage in an ingredients list. It also enables the marketing of "all-natural" ingredients.
Torula finds accepted use in Europe and California for the organic control of olive flies. When dissolved in water, it serves as a food attractant, with or without additional pheromone lures, in McPhail and OLIPE traps, which drown the insects. In field trials in Sonoma County, California, mass trappings reduced crop damage to an average of 30% compared to almost 90% in untreated controls. [5]
Yeast extracts consist of the cell contents of yeast without the cell walls; they are used as food additives or flavorings, or as nutrients for bacterial culture media. They are often used to create savory flavors and umami taste sensations and can be found in a large variety of packaged food including frozen meals, crackers, snack foods, gravy, stock and more. They are rich in B vitamins. Yeast extracts and fermented foods contain glutamic acid, an amino acid which adds an umami flavor. Glutamic acid is found in meat, cheese, fungi and vegetables—such as broccoli and tomatoes. A number of other substances found in yeast extract provide aromas, some meat-like, when allowed to react under heat.
Monosodium glutamate (MSG), also known as sodium glutamate, is a sodium salt of glutamic acid. MSG is found naturally in some foods including tomatoes and cheese in this glutamic acid form. MSG is used in cooking as a flavor enhancer with a savory taste that intensifies the meaty, savory flavor of food, as naturally occurring glutamate does in foods such as stews and meat soups.
Umami, or savoriness, is one of the five basic tastes. It has been described as savory and is characteristic of broths and cooked meats.
Cottage cheese is a curdled milk product with a mild flavor and a creamy, heterogeneous, soupy texture. It is made from skimmed milk by draining curds but retaining some of the whey and keeping the curds loose. An essential step in the manufacturing process distinguishing cottage cheese from other fresh cheeses is the addition of a "dressing" to the curd grains, usually cream, which is mainly responsible for the taste of the product. Cottage cheese is not aged.
Disodium inosinate (E631) is the disodium salt of inosinic acid with the chemical formula C10H11N4Na2O8P. It is used as a food additive and often found in instant noodles, potato chips, and a variety of other snacks.
Feta is a Greek brined white cheese made from sheep's milk or from a mixture of sheep and goat's milk. It is soft, with small or no holes, a compact touch, few cuts, and no skin. Crumbly with a slightly grainy texture, it is formed into large blocks and aged in brine. Its flavor is tangy and salty, ranging from mild to sharp. Feta is used as a table cheese, in salads such as Greek salad, and in pastries, notably the phyllo-based Greek dishes spanakopita "spinach pie" and tyropita "cheese pie". It is often served with olive oil or olives, and sprinkled with aromatic herbs such as oregano. It can also be served cooked, as part of a sandwich, in omelettes, and many other dishes.
Cheesemaking 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.
Guanosine monophosphate (GMP), also known as 5′-guanidylic acid or guanylic acid, is a nucleotide that is used as a monomer in RNA. It is an ester of phosphoric acid with the nucleoside guanosine. GMP consists of the phosphate group, the pentose sugar ribose, and the nucleobase guanine; hence it is a ribonucleoside monophosphate. Guanosine monophosphate is commercially produced by microbial fermentation.
American cheese is a type of processed cheese developed in the 1910s made from cheddar, Colby, or similar cheeses, in conjunction with sodium citrate, which permits it to be pasteurized without its components separating.
Fermented tofu is a Chinese condiment consisting of a form of processed, preserved tofu used in East Asian cuisine. The ingredients typically are soybeans, salt, rice wine and sesame oil or vinegar. In mainland China the product is often freshly distributed. In overseas Chinese communities living in Southeast Asia, commercially packaged versions are often sold in jars containing blocks 2- to 4-cm square by 1 to 2 cm thick soaked in brine with select flavorings.
Strained yogurt, Greek yogurt, yogurt cheese, sack yogurt, kerned yogurt, or Turkish yogurt is yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland, a similar product named skyr is made.
Instant soup is a type of soup designed for fast and simple preparation. Some are homemade, and some are mass-produced on an industrial scale and treated in various ways to preserve them. A wide variety of types, styles and flavors of instant soups exist. Commercial instant soups are usually dried or dehydrated, canned, or treated by freezing.
Glutamate flavoring is the generic name for flavor-enhancing compounds based on glutamic acid and its salts (glutamates). These compounds provide an umami (savory) taste to food.
A low sodium diet is a diet that includes no more than 1,500 to 2,400 mg of sodium per day.
Cheese soup is a type of soup prepared using cheese as a primary ingredient, along with milk, broth and/or stock to form its basis. Various additional ingredients are used in its preparation, and various types and styles of cheese soup exist. It is a part of some cuisines in the world, such as American, Colombian, Mexican, Swiss, French, and Tibetan cuisines. Mass-produced cheese soups may be prepared with the addition of food additives to preserve them and enhance flavor. A list of cheese soups is included in this article.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities. As of 1995, fermented food represented between one quarter and one third of food consumed in Central Europe. More than 260 different species of microbial food culture are identified and described for their beneficial use in fermented food products globally, showing the importance of their use.
A food paste is a semi-liquid colloidal suspension, emulsion, or aggregation used in food preparation or eaten directly as a spread. Pastes are often highly spicy or aromatic, are often prepared well in advance of actual usage, and are often made into a preserve for future use. Common pastes are some fruit preserves, curry pastes, and nut pastes. Purées are food pastes made from already cooked ingredients.
Vegan cheese is a category of non-dairy, plant-based cheese analogues. Vegan cheeses range from soft fresh cheeses to aged and cultured hard grateable cheeses like plant-based Parmesan. The defining characteristic of vegan cheese is the exclusion of all animal products.
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.
Cyberlindnera is a genus of yeasts in the Phaffomycetaceae family. Its name is derived from the Latin word “Ciber,” which originates from “Cibus,” meaning “food” and "sustenance". Early German mycologist Paul Lindner, honored for his contributions to descriptions of Schizosaccharomyces pombe, Saccharomycopsis (Endomyces) fibuligera and other notable species of Saccharomyces and Pichia, is the source of the "-lindnera" portion of the name. The genus has gone through many trials, reevaluations, and verifications to become the organized assortment of species it is today. Species under this genus interact with other organisms in a wide variety of ways and can be found across the globe. They are used by humans for their toxicity, fermentation abilities, and capacity to assimilate many organic compounds.
