Dairy Food
Dairy products or milk products, also known as lacticinia, are food products made from (or containing) milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food items in the Western world such as yogurt, cheese and butter. A facility that produces dairy products is known as a ''dairy''. Dairy products are consumed worldwide to varying degrees (see consumption patterns worldwide). Some people avoid some or all dairy products either because of lactose intolerance, veganism, or other health reasons or beliefs. Production relationship graph Types of dairy product Milk Milk is produced after optional homogenization or pasteurization, in several grades after standardization of the fat level, and possible addition of the bacteria ''Streptococcus lactis'' and '' Leuconostoc citrovorum''. Milk can be broken down into several different categories based on type of product produced, including c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk Glass
Milk glass is an opaque or translucent, milk white or colored glass that can be blown or pressed into a wide variety of shapes. First made in Venice in the 16th century, colors include blue, pink, yellow, brown, black, and white. Principle Milk glass contains dispersion of particles with refractive index significantly different from the glass matrix, which light scattering, scatter light by the Tyndall scattering mechanism. The size distribution and density of the particles control the overall effect, which may range from mild opalization to opaque white. Some glasses are somewhat more blue from the side, and somewhat red-orange in pass-through light. The particles are produced via addition of opacifiers to the melt. Some opacifiers can be insoluble and only dispersed in the melt. Others are added as precursors and react in the melt, or dissolve in the molten glass and then precipitate as crystals on cooling; this is similar to color production in Glass coloring and color mark ...

Added Sugar
Added sugars or free sugars are sugar carbohydrates (caloric sweeteners) added to food and beverages at some point before their consumption. These include added carbohydrates (monosaccharides and disaccharides), and more broadly, sugars naturally present in honey, syrup, and fruits. They can take multiple chemical forms, including sucrose (table sugar), glucose (dextrose), and fructose. Medical consensus holds that added sugars contribute little nutritional value to food, leading to a colloquial description as "empty calories". Overconsumption of sugar is correlated with excessive calorie intake and increased risk of weight gain and various diseases. Uses United States In the United States, added sugars may include sucrose or high-fructose corn syrup, both primarily composed of about half glucose and half fructose. Other types of added sugar ingredients include beet and cane sugars, malt syrup, maple syrup, pancake syrup, fructose sweetener, liquid fructose, fruit juice conc ...

Evaporated Milk
Evaporated milk, known in some countries as "unsweetened condensed milk", is a shelf-stable canned cow’s milk product where about 60% of the water has been removed from fresh milk. It differs from sweetened condensed milk, which contains added sugar. Sweetened condensed milk requires less processing to preserve since the added sugar inhibits bacterial growth. The production process involves the evaporation of 60% of the water from the milk, followed by homogenization, canning, and heat-sterilization. Evaporated milk takes up half the space of its nutritional equivalent in fresh milk. When the liquid product is mixed with a proportionate amount of water (150%), evaporated milk becomes the rough equivalent of fresh milk. This makes evaporated milk attractive for some purposes as it can have a shelf life of months or even years, depending upon the fat and sugar content. This made evaporated milk very popular before refrigeration as a safe and reliable substitute for perisha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condensed Milk
Condensed milk is cow's milk from which water has been removed (roughly 60% of it). It is most often found with sugar added, in the form of ''sweetened condensed milk'' (SCM), to the extent that the terms "condensed milk" and "sweetened condensed milk" are often used interchangeably today. Sweetened condensed milk is a very thick, sweet product, which when canned can last for years without refrigeration if not opened. The product is used in numerous dessert dishes in many countries. A related product is evaporated milk, which has undergone a lengthier preservation process because it is not sweetened. Evaporated milk is known in some countries as unsweetened condensed milk. Both products have a similar amount of water removed. History According to the writings of Marco Polo, in the thirteenth century the Tatars were able to condense milk. Marco Polo reported that of milk paste was carried by each man, who would subsequently mix the product with water. However, this probably ...

Scalded Milk
Scalded milk is dairy milk that has been heated to . At this temperature, bacteria are killed, enzymes in the milk are destroyed, and many of the proteins are denatured. Since most milk sold today is pasteurized, which accomplishes the first two goals, milk is typically scalded to increase its temperature, or to change the consistency or other cooking interactions due to the denaturing of proteins. During scalding, a milk watcher (a cooking utensil) may be used to prevent both boiling over and scorching (burning) of the milk. Uses *Scalded milk is called for in the original recipes for Béchamel sauce, as adding hot liquid, including milk, to a roux was thought less likely to make a lumpy sauce or one tasting of raw flour. *Scalded and cooled milk is used in bread and other yeast doughs, as pasteurization does not kill all bacteria, and with the wild yeasts that may also be present, these can alter the texture and flavor. Recipes old enough to have been based on hand-milked, sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk Chocolate
Milk chocolate is a solid chocolate confectionery containing cocoa, sugar and milk. Chocolate was originally sold and consumed as a beverage in pre-Columbian times, and upon its introduction to Western Europe. Major milk chocolate producers include Ferrero, Hershey, Mondelez, Mars and Nestlé. Between them, they are responsible for over half of the chocolate sold worldwide. Although four-fifths of all milk chocolate is sold in the United States and Europe, increasingly large amounts are consumed in China and Latin America. While taste and texture have been key to its success, milk chocolate has also historically been promoted as a healthy food, particularly for children. Recent evidence has shown that it may provide antioxidant health benefits. The word ''chocolate'' arrived in the English language about 1600, but initially described dark chocolate. The first use of the term "milk chocolate" was for a beverage brought to London from Jamaica in 1687, but it was not until the Sw ...

Whole Milk
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) 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. As an agricultural product, dairy milk is collected from farm animals. In 2011, dairy farms produced around of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products. Because there is an ever-increasing demand for dairy products within India, it could eventually become a net importer of dairy products. New Zealand, Germany and the Netherlands are the largest exporters of mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skim Milk
Skimmed milk (British English), or skim milk (American English), is made when all the milkfat is removed from whole milk. It tends to contain around 0.1% fat. Background Historically, skimmed milk was used for fattening pigs, and was recommended as "not only the very best supplement for growing pigs, but is of almost equal value for fattening purposes" as it "furnishes a complete protein" and makes the feed "more palatable". Terminology In the United Kingdom, milk is traditionally marketed and labelled as follows: * Whole milk (around 3.0–4% fat) – Plastic bottles marketed in blue packaging. * Semi-skimmed milk (around 1.8% fat) – Plastic bottles are marketed in green packaging. * Skimmed milk (around 0.1% fat) – Plastic bottles are marketed in red packaging. * Channel Island milk (around 5–5.5% fat) Often referred to as gold top, although this varies. Additionally, some supermarkets in the UK now market milk as: * 1% fat milk – Normally sold in purple or oran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leuconostoc Citrovorum
''Leuconostoc'' is a genus of gram-positive bacteria, placed within the family of Lactobacillaceae. They are generally ovoid cocci often forming chains. ''Leuconostoc'' spp. are intrinsically resistant to vancomycin and are catalase-negative (which distinguishes them from staphylococci). All species within this genus are heterofermentative and are able to produce dextran from sucrose. They are generally slime-forming. Blamed for causing the 'stink' when creating a sourdough starter, some species are also capable of causing human infection. Because they are an uncommon cause of disease in humans, standard commercial identification kits are often unable to identify the organism. ''Leuconostoc'' spp., along with other lactic acid bacteria such as '' Pediococcus'' and '' Lactobacillus'', are responsible for the fermentation of cabbage, making it sauerkraut. In this process, fresh cabbage is fermented in a light brine, where the sugars in the cabbage are transformed by lac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streptococcus Lactis
''Lactococcus lactis'' is a Gram-positive bacterium used extensively in the production of buttermilk and cheese, but has also become famous as the first genetically modified organism to be used alive for the treatment of human disease. ''L. lactis'' cells are cocci that group in pairs and short chains, and, depending on growth conditions, appear ovoid with a typical length of 0.5 - 1.5 µm. ''L. lactis'' does not produce spores ( nonsporulating) and are not motile ( nonmotile). They have a homofermentative metabolism, meaning they produce lactic acid from sugars. They've also been reported to produce exclusive L-(+)-lactic acid. However, reported D-(−)-lactic acid can be produced when cultured at low pH. The capability to produce lactic acid is one of the reasons why ''L. lactis'' is one of the most important microorganisms in the dairy industry. Based on its history in food fermentation, ''L. lactis'' has generally recognized as safe (GRAS) status, with few case reports ...

Pasteurization
Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety. By the year 1999, most liquid products were heat treated in a continuous system where heat can be applied using a plate heat exchanger or the direct or indirec ...
