Mageu
Mageu (Setswana spelling), Mahewu (Shona/Chewa/ Nyanja spelling), Mahleu (Sesotho spelling), Magau (xau-Namibia) (Khoikhoi spelling), Madleke (Tsonga spelling), Mabundu (Tshivenda spelling), maHewu, amaRhewu (Xhosa spelling) or amaHewu ( Zulu and Northern Ndebele spelling) is a traditional Southern African non-alcoholic drink among many of the Chewa/Nyanja, Shona, Ndebele, Nama Khoikhoi and Damara people, Sotho people, Tswana people and Nguni people made from fermented mealie pap. Home production is still widely practised, but the drink is also available at many supermarkets, being produced at factories. Its taste is derived predominantly from the lactic acid that is produced during fermentation, but commercial mageu is often flavoured and sweetened, much in the way commercially available yogurt is. Similar beverages are also made in other parts of Africa. Fermentation process Thin mealie pap (maize meal) is prepared, to which wheat flour is added, providing the inoculum of l ...

Southern Africa
Southern Africa is the southernmost region of Africa. No definition is agreed upon, but some groupings include the United Nations geoscheme for Africa, United Nations geoscheme, the intergovernmental Southern African Development Community, and the #Definitions and Usage, physical geography definition based on the physical characteristics of the land. The most restrictive definition considers the region of Southern Africa to consist of Botswana, Eswatini, Lesotho, Namibia, and South Africa, while other definitions also include several other countries from the area. Defined by physical geography, Southern Africa is home to several river systems; the Zambezi, Zambezi River is the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, it flows over Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist a ...

Damara People
The Damara, plural Damaran (Khoekhoegowab: ǂNūkhoen, ''Black people'', , referring to their extended stay in hilly and mountainous sites, also called at various times the Daman or the Damaqua) are an ethnic group who make up 8.5% of Namibia, Namibia's population. They speak the Khoekhoe language (like the Nama people) and the majority live in the northwestern regions of Namibia, however, they are also found widely across the rest of the country. Genetic studies have found that Damara are closely related to neighbouring Himba people, Himba and Herero people, Herero people, consistent with an origin from Bantu speakers who shifted to a different language and culture. Their name in their own language is the ''"Daman"'' (where the ''"-n"'' is just the Khoekhoe plural ending). The name ''"Damaqua"'' stems from the addition of the Khoekhoe suffix ''"-qua/khwa"'' meaning "people" (found in the names of other Southern African peoples like the Nama people, Nama and the Griqua people ...

Food Fortification
Food fortification is the addition of micronutrients (essential trace elements and vitamins) to food products. Food enrichment specifically means adding back nutrients lost during food processing, while fortification includes adding nutrients not naturally present.World Health Organization and Food and Agriculture Organization of the United Nations Guidelines on food fortification with micronutrients. 2006 ited on 2011 Oct 30 Food manufacturers and governments have used these practices since the 1920s to help prevent nutrient deficiencies in populations.

Shelf-life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tyres, batteries, and many other perishable items. In some regions, an advisory ''best before'', mandatory ''use by'' or ''freshness date'' is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions. Background Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.

Pasteurization
In food processing, pasteurization (American and British English spelling differences#-ise, -ize (-isation, -ization), also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than , to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most Endospore, bacterial spores survive the process. Pasteurization 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 for food preservation and food safety. By the year 1999, most liquid products were heat treated in a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inoculum (fermentation Starter)
A fermentation starter (called simply starter within the corresponding context, sometimes called a mother) is a preparation to assist the beginning of the fermentation process in preparation of various foods and alcoholic drinks. Food groups where they are used include breads, especially sourdough bread, and cheese. A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. These starters are formed using a specific cultivation medium and a specific mix of fungal and bacterial strains.Norman F. Haard, S.A. Odunfa, Cherl-Ho Lee, R.

Yogurt
Yogurt (; , from , ; also spelled yoghurt, yogourt or yoghourt) is a food produced by bacterial Fermentation (food), fermentation of milk. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture (food), texture and characteristic tart flavor. Cow's milk is most commonly used to make yogurt. Milk from water buffalo, goats, sheep, ewes, mares, camels, and yaks is also used to produce yogurt. The milk used may be Milk#Creaming and homogenization, homogenized or not. It may be pasteurized or raw milk, raw. Each type of milk produces substantially different results. Yogurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus, ''Lactobacillus delbrueckii'' subsp. ''bulgaricus'' and ''Streptococcus thermophilus'' bacteria. Other Lactobacillus, lactobacilli and Bifidobacterium, bifidobacteria are sometimes added during or after culturing yogurt. Some countries require yogurt to contain a spec ...

Fermentation
Fermentation is a type of anaerobic metabolism which harnesses the redox potential of the reactants to make adenosine triphosphate (ATP) and organic end products. Organic molecules, such as glucose or other sugars, are catabolized and reduced by donating their electrons to other organic molecules (cofactors, coenzymes, etc.). Fermentation is important in several areas of human society. Humans have used fermentation in the production and preservation of food for 13,000 years. It has been associated with health benefits, unique flavor profiles, and making products have better texture. Humans and their livestock also benefit from fermentation from the microbes in the gut that release end products that are subsequently used by the host for energy. Perhaps the most commonly known use for fermentation is at an industrial level to produce commodity chemicals, such as ethanol and lactate. Ethanol is used in a variety of alcoholic beverages (beers, wine, and spirits) while lactate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactic Acid
Lactic acid is an organic acid. It has the molecular formula C3H6O3. It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate (or the lactate anion). The name of the derived acyl group is lactoyl. In solution, it can ionize by a loss of a proton to produce the lactate ion . Compared to acetic acid, its p''K'' is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group. Lactic acid is chiral, consisting of two en ...

Porridge
Porridge is a food made by heating, soaking or boiling ground, crushed or chopped starchy plants, typically grain, in milk or water. It is often cooked or served with added flavourings such as sugar, honey, fruit, or syrup to make a sweet cereal, or it can be mixed with spices, meat, or vegetables to make a Savoury (dish), savoury dish. It is usually served hot in a bowl, depending on its consistency. Oat porridge, (known as oatmeal in North America) is one of the most common types of porridge. Gruel is a thinner version of porridge and congee is a savoury variation of porridge of Asian cuisine, Asian origin. Type of grains The term "porridge" is used in British English (Britain, Ireland, Australia and New Zealand) specifically for oatmeal. This is a hot mixture of oatmeal or oats slowly cooked with water or milk. It is typically eaten for breakfast by itself or with other ingredients, including salt, sugar, fruit, milk, cream, or butter. Other grains used for porridge include ...

Maize
Maize (; ''Zea mays''), also known as corn in North American English, is a tall stout grass that produces cereal grain. It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange, it has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice. Much maize is used for animal feed, whether as grain or as the whole plant, which can either be baled or made into the more palatable silage. Sugar-rich varieties called sw ...

Fermentation (food)
In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term "fermentation" sometimes refers specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, and cider. However, similar processes take place in the leavening of bread (CO2 produced by yeast activity), and in the preservation of sour foods with the production of lactic acid, such as in sauerkraut and yogurt. Humans have an enzyme that gives us an enhanced ability to break down ethanol. Other widely consumed fermented foods include vinegar, olives, and cheese. More localized foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, and fish. His ...
