A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both male and female condoms. With proper use—and use at every act of intercourse—women whose partners use male condoms experience a 2% per-year pregnancy rate. With typical use the rate of pregnancy is 18% per-year. Their use greatly decreases the risk of gonorrhea, chlamydia, trichomoniasis, hepatitis B, and HIV/AIDS. To a lesser extent, they also protect against genital herpes, human papillomavirus (HPV), and syphilis.
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibodies that strengthen the immune system, and thus reduces the risk of many diseases. Milk contains many nutrients, including protein and lactose.
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.
Casein is a family of related phosphoproteins that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and buffalo milk have a higher casein content than other types of milk with human milk having a particularly low casein content.
A gluten-free casein-free diet, also known as a gluten-free dairy-free diet, is a diet that does not include gluten, and casein. Despite an absence of scientific evidence, there have been advocates for the use of this diet as a treatment for autism and related conditions.
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 is a byproduct brought out during the making of acid types of dairy products, such as cottage cheese or strained yogurt.
Durex is a brand of condoms and personal lubricants owned by the British company Reckitt Benckiser. It was initially developed in London under the purview of the London Rubber Company and British Latex Products Ltd, where it was manufactured between 1932 and 1994. The London Rubber Company was formed in 1915, and the Durex brand name was launched in 1929 although London Rubber did not begin manufacturing own-brand condoms until 1932, in collaboration with a rubber technology student from Poland named Lucian Landau. The first book on The London Rubber Company and the history of Durex condoms, written by Jessica Borge, was published in September 2020 by McGill-Queen's University Press.
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.
Blue cheese is semi-soft cheese with a sharp, salty flavor. It is made with cultures of the edible mold Penicillium, giving it spots or veins throughout the cheese in shades of blue or green. It carries a distinct smell, either from the mold or from various specially cultivated bacteria such as Brevibacterium linens, which also causes foot odor and other human body odors.
Whey protein is a mixture of proteins isolated from whey, the liquid material created as a by-product of cheese production. The proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin and immunoglobulins. Glycomacropeptide also makes up the third largest component but is not a protein. Whey protein is commonly marketed as a protein supplement, and various health claims have been attributed to it. A review published in 2010 in the European Food Safety Authority Journal concluded that the provided literature did not adequately support the proposed claims. For muscle growth, whey protein has been shown to be slightly better compared to other types of protein, such as casein or soy.
Bareback sex is physical sexual activity, especially sexual penetration, without the use of a condom. The topic primarily concerns anal sex between men who have sex with men without the use of a condom, and may be distinguished from unprotected sex because bareback sex denotes the deliberate act of forgoing condom use.
Easy Cheese is the trademark for a processed cheese spread product distributed by Mondelēz International. It is also referred to as "spray cheese", "cheese wizz", "cheese whiz" or simply "cheese in a can", and is similar to "squeeze cheese". Easy Cheese is packaged in a metal can filled with air covered with a plastic cap that reveals a straight, flexible nozzle where the cheese is extruded.
The production of wine often includes a process called fining, in which fining agents are added to wine to remove proteins, yeast, and other suspended organic particles, and later filtered out. Fining agents can be either animal, carbon, or clay-based. Animal-based fining agents include gelatin, isinglass, egg white (albumen), and casein.
Galalith is a synthetic plastic material manufactured by the interaction of casein and formaldehyde. The commercial name is derived from the Ancient Greek words γάλα and λῐ́θος. It is odourless, insoluble in water, biodegradable, non-allergenic, antistatic and virtually nonflammable. It was produced under other names such as aladdinite, Casolith and lactoloid.
Clarified butter is milk fat rendered from butter to separate the milk solids and water from the butterfat. Typically, it is produced by melting butter and allowing the components to separate by density. The water evaporates, some solids float to the surface and are skimmed off, and the remainder of the milk solids (casein) sink to the bottom and are left behind when the butterfat is poured off or separated with a separatory funnel or a gravy fat separator. This butterfat is the clarified butter.
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.
Milk paint is a nontoxic milk-based paint. It can be made from milk and lime, generally with pigments added for color. In other recipes, borax is mixed with milk's casein protein in order to activate the casein and as a preservative.
Measure B, also known as the County of Los Angeles Safer Sex In the Adult Film Industry Act, is the law that requires the use of condoms in all vaginal and anal sex scenes in pornography productions filmed in Los Angeles County, California. The measure also requires porn production companies to obtain a health permit prior to production and to post the permit and a notice to performers regarding condom use during production. All individuals involved will also be required to pay $1,600 every 2 years.
Sour cream or soured cream is a dairy product obtained by fermenting regular cream with certain kinds of lactic acid bacteria. The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream. Its name comes from the production of lactic acid by bacterial fermentation, which is called souring. Crème fraîche is one type of sour cream with a high fat content and less sour taste.
Milk fiber or milk wool is a type of Azlon, a regenerated protein fiber based on the casein protein found in milk. There are several trade names for milk-casein-based fibers, including Lanital, Fibrolane and Aralac.
