Chewiness is the mouthfeel sensation of labored chewing due to sustained, elastic resistance from the food. Foods typically considered chewy include caramel, rare steak, [1] and chewing gum. Other foods where this is an important part of the experience of eating include springy cheeses [2] and apples. [3]
Chewiness is empirically measured by the metrics of chew count [4] and chew rate. [5]
Pizza cheese encompasses several varieties and types of cheeses and dairy products that are designed and manufactured for use specifically on pizza. These include processed and modified cheese, such as mozzarella-like processed cheeses and mozzarella variants. The term can also refer to any type of cheese suitable for use on pizza. The most popular cheeses used in the preparation of pizza are mozzarella, provolone, cheddar and Parmesan. Emmental, pecorino romano and ricotta are often used as toppings, and processed pizza cheeses manufactured specifically for pizza are mass-produced. Some mass-produced pizza cheeses are frozen after manufacturing and shipped frozen.
Gouda cheese is a creamy, yellow cow's milk cheese originating from the Netherlands. It is one of the most popular and produced cheeses worldwide. The name is used today as a general term for numerous similar cheeses produced in the traditional Dutch manner.
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.
Blue cheese is any of a wide range of cheeses made with the addition of cultures of edible molds, which create blue-green spots or veins through the cheese. Blue cheeses vary in taste from very mild to strong, and from slightly sweet to salty or sharp; in colour from pale to dark; and in consistency from liquid to hard. They may have a distinctive smell, either from the mold or from various specially cultivated bacteria such as Brevibacterium linens.
Streptococcus thermophilus formerly known as Streptococcus salivarius subsp. thermophilus is a gram-positive bacterium, and a fermentative facultative anaerobe, of the viridans group. It tests negative for cytochrome, oxidase, and catalase, and positive for alpha-hemolytic activity. It is non-motile and does not form endospores. S. thermophilus is fimbriated.
George Malcolm Trout was an American dairy industry pioneer, writer, researcher, and professor emeritus in food science at Michigan State University. Trout is credited with finding the key to the creation of homogenized milk.
Rumenic acid, also known as bovinic acid, is a conjugated linoleic acid (CLA) found in the fat of ruminants and in dairy products. It is an omega-7 trans fatty acid. Its lipid shorthand name is cis-9, trans-11 18:2 acid. The name was proposed by Kramer et al. in 1998. It can be considered as the principal dietary form, accounting for as much as 85-90% of the total CLA content in dairy products.
The American Dairy Science Association (ADSA) is a non-profit professional organization for the advancement of dairy science. ADSA is headquartered in Champaign, Illinois.
Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia). It occurs following parturition (birth), at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium. "Fever" is a misnomer, as the disease generally does not cause elevated body temperature. Milk fever is more commonly seen in older animals and in certain breeds.
Κ-casein, or kappa casein, is a mammalian milk protein involved in several important physiological processes. Chymosin splits K-casein into an insoluble peptide and water-soluble glycomacropeptide (GMP). GMP is responsible for an increased efficiency of digestion, prevention of neonate hypersensitivity to ingested proteins, and inhibition of gastric pathogens. The human gene for κ-casein is CSN3.
The fat content of milk is the proportion of milk, by weight, made up by butterfat. The fat content, particularly of cow's milk, is modified to make a variety of products. The fat content of milk is usually stated on the container, and the color of the label or milk bottle top varied to enable quick recognition.
Charles Roy Henderson was an American statistician and a pioneer in animal breeding — the application of quantitative methods for the genetic evaluation of domestic livestock. This is critically important because it allows farmers and geneticists to predict whether a crop or animal will have a desired trait, and to what extent the trait will be expressed. He developed mixed model equations to obtain best linear unbiased predictions of breeding values and, in general, any random effect. He invented three methods for the estimation of variance components in unbalanced settings of mixed models, and invented a method for constructing the inverse of Wright's numerator relationship matrix based on a simple list of pedigree information. He, with his Ph.D. student Shayle R. Searle, greatly extended the use of matrix notation in statistics. His methods are widely used by the domestic livestock industry throughout the world and are a cornerstone of linear model theory.
A cannulated cow or fistulated cow refers to a cow that has been surgically fitted with a cannula. A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
The Latxa is a breed of domestic sheep native to the Basque Country of Spain. Mostly contained within the provinces of Biscay, Gipuzkoa and Navarre, Latxa are dairy sheep whose unpasteurized milk is used to produce Idiazábal and Roncal cheeses. There are two sub-types of the breed, a dark-faced and a blonde.
Lore Alford Rogers was an American bacteriologist and dairy scientist. He is credited with discovering that butter made from pasteurized sweet cream remained fresher than that made from sour ripened cream, while suggesting that surplus milk could still be sold as concentrated sour milk products. He refined the steps for manufacture of high quality Swiss cheese and, new to the United States, production of Roquefort cheese. He was instrumental in finding ways to discourage fungal growth in sweetened condensed milk and preventing losses in evaporated milk from heat coagulation.
Penicillium caseifulvum is a fungus species of the genus of Penicillium which occurs on the surface of blue cheese and causes discoloration in form of brown spots.
Carbonated milk or soda milk is a carbonated soft drink. It can be made from powdered milk or fresh milk, and often has added flavor. In addition to modified mouthfeel, carbonated milk also has a longer shelf-life than similarly processed flat milk and a different flavor. It is sold by several companies and is most popular in Asia.
A Babcock bottle is a clear glass flask with a long graduated neck, used in the Babcock test to evaluate the cream contents of milk. It is also called a Babcock milk test bottle, milk test bottle, cream test bottle, and other similar names.
Edwin Michael Foster was an American microbiologist, specializing in food microbiology. He was the president of the American Society for Microbiology (ASM) in 1970.
