Thermal Cooking
A thermal cooker, or a vacuum flask cooker, is a cooking device that uses thermal insulation to retain heat and cook food without the continuous use of fuel or other heat source. It is a modern implementation of a haybox, which uses hay or straw to insulate a cooking pot. History The earliest known thermal cooker dates from the Medieval period in Europe. After heating over a fire, a hot, earthenware pot containing food was placed in another, larger pot, box or hole in the ground, insulated by hay, moss, dry leaves or other material, and covered. The heat conserved within would slowly cook the food inside, saving fuel and work. An example of this type of cooker was found in Wales by a Monmouth Archaeological Society excavation. Medieval instructions for cooking without fire taken from an Anglo-Norman manuscript in the British Library: A league is about three miles (five kms), so the length of cooking time is approximately five to seven hours.

Vacuum Flask Cooker Open
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But high ...

Asian Supermarket
In the West or non-Asian countries, an Asian supermarket largely describes a category of grocery stores that focuses and stocks items and products imported from countries located in the Far East (e.g. East, Southeast and South Asia). These stores go further than a typical quintessential supermarket in that they sell general merchandise, goods, and services related to specific Asian countries of origin, immigrant communities or the ethnic enclave that the store may be located in. They would also often tend to diversify by carrying products from other fellow Asian countries; Japanese supermarkets would carry some Chinese, Indonesian, Korean and Singaporean products; Korean supermarkets carry some Chinese and Japanese products; Taiwanese supermarkets carry Chinese, Korean, Japanese, Thai, Vietnamese products, and so on. Overview Asian supermarkets carry items and ingredients generally well-suited for Asian cuisines and simply not found or considerably more expensive in most Weste ...

Sous-vide
Sous vide (; French for 'under vacuum'), also known as low-temperature, long-time (LTLT) cooking, is a method of cooking in which food is placed in a plastic pouch or a glass jar and cooked in a water bath for longer than usual cooking times (usually one to seven hours, and up to 72 or more hours in some cases) at a precisely regulated temperature. The temperature is much lower than usually used for cooking, typically around for red meat, for poultry, and higher for vegetables. The intent is to cook the item evenly, ensuring that the inside is properly cooked without overcooking the outside, and to retain moisture. History Sous vide cooking is characterized by low-temperature cooking, a longer period of cooking than conventional cooking, a container (such as a plastic bag) that separates the food from its heating environment, and pressurized enclosure using full or partial vacuum. Low-temperature cooking was first described by Benjamin Thompson, Count Rumford in 1799. He us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haybox
A haybox, straw box, fireless cooker, insulation cooker, wonder oven, self-cooking apparatus, norwegian cooker or retained-heat cooker is a cooker that utilizes the heat of the food being cooked to complete the cooking process. Food items to be cooked are heated to boiling point, and then insulated. Over a period of time, the food items cook by the heat captured in the insulated container. Generally, it takes three times the normal cooking time to cook food in a haybox. History Hayboxes are so called because hay or straw were the commonly used insulators. Pots of food would be brought to a boil and then placed in a box filled with hay or straw. Additional hay or straw would be added around and on top of the pot. The inventor Karl von Drais developed a novel form of haybox in the first part of the 19th century. During World War II, hayboxes were used as a way of conserving rationed cooking fuel. Campers and hikers have used variations of hayboxes for years, heating their foo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wonderbag
Wonderbag is a stand-alone, non-electric insulated bag designed to reduce the amount of fuel required in the cooking of food in developing countries. Instead of being placed on a stove for the duration of the cooking period, food is instead heated to a hot enough temperature then transferred to the Wonderbag, which uses the principle of thermal insulation to continue cooking, and keeps food warm without needing additional fire or heat. Working on the principle of thermal cooking, the Wonderbag is estimated to save up to 30% of the total fuel costs associated with cooking with Kerosene ("paraffin") alone. In developing countries there are numerous advantages for the product, as it immediately helps ease deforestation of natural reserves, and it frees up those who would spend their time gathering the extra wood for fire fuel. Designed by Durban, South Africa-based entrepreneur Sarah Collins of Natural Balance, and poverty activist Moshy Mathe, the Wonderbag is aimed at societi ...

Phytohaemagglutinin
Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants, especially certain legumes. PHA actually consists of two closely related proteins, called leucoagglutinin (PHA-L) and PHA-E. These proteins cause blood cells to clump together. PHA-E cause erythrocytes (red blood cells) to clump. PHA-L causes leukocytes (white blood cells) to clump. Phytohaemagglutinin has carbohydrate-binding specificity for a complex oligosaccharide containing galactose, ''N''-acetylglucosamine, and mannose. It is found in the highest concentrations in uncooked red kidney beans and white kidney beans (also known as cannellini), and it is also found in lower quantities in many other types of green beans and other common beans ('' Phaseolus vulgaris''), as well as broad beans (''Vicia faba'') such as fava beans. It has a number of physiological effects and is used in medical research. In high doses, it is a toxin. The lectin has a number of effects on cell metabolism; it induces mito ...

Vicia Faba
''Vicia faba'', commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieties with smaller, harder seeds that are fed to horses or other animals are called field bean, tic bean or tick bean. Horse bean, ''Vicia faba'' var. ''equina'' Pers., is a variety recognized as an accepted name. This legume is very common in Southern European, Northern European, East Asian, Latin American and North African cuisines. Some people suffer from favism, a hemolytic response to the consumption of broad beans, a condition linked to a metabolism disorder known as G6PDD. Otherwise the beans, with the outer seed coat removed, can be eaten raw or cooked. In young plants, the outer seed coat can be eaten, and in very young plants, the seed pod can be eaten.

Kidney Bean
The kidney bean is a variety of the common bean (''Phaseolus vulgaris''). It resembles a human kidney and thus is named after such. Red kidney beans should not be confused with other red beans, such as adzuki beans. Classification There are different classifications of kidney beans, such as: *Red kidney bean (also known as: common kidney bean, rajma in India, surkh (red) lobia in Pakistan). *Light speckled kidney bean (and long shape light speckled kidney bean). *Red speckled kidney bean (and long shape light speckled kidney bean). *White kidney bean (also known as cannellini in Italy, lobia in India, or safaid (white) lobia in Pakistan). Nutrition Kidney beans, cooked by boiling, are 67% water, 23% carbohydrates, 9% protein, and contain negligible fat (table). In a 100-gram reference amount, cooked kidney beans provide of food energy, and are a rich source (20% or more of the Daily Value, DV) of protein, folate (33% DV), iron (22% DV), and phosphorus (20% DV), with moderate ...

Danger Zone (food Safety)
The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly . The FSIS stipulates that potentially hazardous food should not be stored at temperatures in this range in order to prevent foodborne illness (for example, a refrigerator's temperature must be kept below ), and that food that remains in this zone for more than two hours should not be consumed. Foodborne microorganisms grow much faster in the middle of the zone, at temperatures between . In the UK and NI, the Danger Zone is defined as 8 °C - 63 °C Food-borne bacteria, in large enough numbers, may cause food poisoning, symptoms similar to gastroenteritis or "stomach flu" (a misnomer, as true influenza primarily affects the respiratory system). Some of the symptoms include stomach cramps, nausea, vomiting, diarrhea, and fever. Food-borne illness becomes more dangerous in cert ...

Low-temperature Cooking
Low-temperature cooking is a cooking technique using temperatures in the range of about for a prolonged time to cook food. Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of about , and using a combi steamer providing exact temperature control. The traditional cooking pit also cooks food at low temperature. Cooking food by a low-temperature method does not necessarily imply that the ''internal'' temperature of the food is lower than by traditional cooking. In the American South, this style of cooking is sometimes referred to as "low and slow". History Low-temperature cooking has been used for a long time; evidence of its use can be found in indigenous cultures. Samoans and Tongans slow-cook meat in large pits for celebrations and ceremonies. However, the technique was not scientifically examined until the 18th century, when Benjamin Thompson "described how he had left a joint of m ...

Slow Cooker
A slow cooker, also known as a crock-pot (after a trademark owned by Sunbeam Products but sometimes used generically in the English-speaking world), is a countertop electrical cooking appliance used to simmer at a lower temperature than other cooking methods, such as baking, boiling, and frying. This facilitates unattended cooking for many hours of dishes that would otherwise be boiled: pot roast, soups, stews and other dishes (including beverages, desserts and dips). History Slow cookers achieved popularity in the US during the 1940s, when many women began to work outside the home. They could start dinner cooking in the morning before going to work and finish preparing the meal in the evening when they came home. The Naxon Utilities Corporation of Chicago, under the leadership of electrical engineer Irving Naxon (born Irving Nachumsohn), developed the Naxon Beanery All-Purpose Cooker for the purposes of cooking a bean meal. Naxon was inspired by a story from his mother whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
