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] |

Sous Vide Cooking
The Sous region (also spelt Sus, Suss, Souss or Sousse) ( ar, سوس, sūs, shi, ⵙⵓⵙ, sus) is an area in mid-southern Morocco. Geologically, it is the Alluvial plain, alluvial basin of the Sous River (''Asif n Sus''), separated from the Sahara desert by the Anti-Atlas Mountains. The natural vegetation in the Sous region is savanna dominated by the argan (''Argania spinosa''), a local endemic (ecology), endemic tree found nowhere else; part of the area is now a UNESCO Biosphere Reserve to protect this unique habitat. The region of Sous is generally fertile and has a high agricultural production. History Medieval Arabic geographers generally divided the Sous region into two distinct sub-regions: ''al-Sūs al-Aqṣā'', or "farther Sus", and ''al-Sūs al-Adnā'', or "nearer Sus". Sus al-Aqsa consisted of the southern/western part, and Sus al-Adna consisted of the northern/eastern part; however, there were never any precise boundaries between the two. The capital of the Sous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Anaerobic Organism
An anaerobic organism or anaerobe is any organism that does not require molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment. Anaerobes may be unicellular (e.g. protozoans, bacteria) or multicellular. Most fungi are obligate aerobes, requiring oxygen to survive. However, some species, such as the Chytridiomycota that reside in the rumen of cattle, are obligate anaerobes; for these species, anaerobic respiration is used because oxygen will disrupt their metabolism or kill them. Deep waters of the ocean are a common anoxic environment. First observation In his letter of 14 June 1680 to The Royal Society, Antonie van Leeuwenhoek described an experiment he carried out by filling two identical glass tubes about halfway with crushed pepper powder, to which some clean rain water was added. Van Leeuwenhoek sealed one of the glass tubes using a flame an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clostridium Botulinum
''Clostridium botulinum'' is a Gram-positive, rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce the neurotoxin botulinum. The botulinum toxin can cause botulism, a severe flaccid paralytic disease in humans and other animals, and is the most potent toxin known to mankind, natural or synthetic, with a lethal dose of 1.3–2.1 ng/kg in humans.(2010).

Pregnancy
Pregnancy is the time during which one or more offspring develops ( gestates) inside a woman's uterus (womb). A multiple pregnancy involves more than one offspring, such as with twins. Pregnancy usually occurs by sexual intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the last menstrual period (LMP), a span known as the gestational age. This is just over nine months. Counting by fertilization age, the length is about 38 weeks. Pregnancy is "the presence of an implanted human embryo or fetus in the uterus"; implantation occurs on average 8–9 days after fertilization. An '' embryo'' is the term for the developing offspring during the first seven weeks following implantation (i.e. ten weeks' gestational age), after which the term ''fetus'' is used until birth.

Pasteurized
Pasteurization American and British English spelling differences#-ise, -ize (-isation, -ization), 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 Endospore, 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 cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immunodeficiency
Immunodeficiency, also known as immunocompromisation, is a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection and environmental factors, such as nutrition. Immunocompromisation may also be due to genetic diseases/flaws such as SCID. In clinical settings, immunosuppression by some drugs, such as steroids, can either be an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti- rejection measure and in patients with an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. A person who has an immunodeficiency of any kind is said to be immunocompromised. An immunocompromised individual may particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Searing
Searing (or pan searing) is a technique used in grilling, baking, braising, roasting, sautéing, etc., in which the surface of the food (usually meat such as beef, poultry, pork, seafood) is cooked at high temperature until a browned crust forms. Similar techniques, browning and blackening, are typically used to sear all sides of a particular piece of meat, fish, poultry, etc. before finishing it in the oven. To obtain the desired brown or black crust, the meat surface must exceed , so searing requires the meat surface be free of water, which boils at around . Although often said to "lock in the moisture" or "seal in the juices", in fact, searing results in a greater loss of moisture than cooking to the same internal temperature without searing. Page 161, "The Searing Question". Nonetheless, it remains an essential technique in cooking meat for several reasons: *The browning creates desirable flavors through the Maillard reaction. *The appearance of the food is usually impr ...

Steak
A steak is a thick cut of meat generally sliced across the muscle fibers, sometimes including a bone. It is normally grilled or fried. Steak can be diced, cooked in sauce, such as in steak and kidney pie, or minced and formed into patties, such as hamburgers. Steaks are cut from animals including cattle, bison, camel, goat, horse, kangaroo, sheep, ostrich, pigs, reindeer, turkey, deer, and zebu, as well as various types of fish, especially salmon and large fish such as swordfish, shark, and marlin. For some meats, such as pork, lamb and mutton, chevon, and veal, these cuts are often referred to as chops. Some cured meat, such as gammon, is commonly served as steak. Grilled portobello mushroom may be called mushroom steak, and similarly for other vegetarian dishes. Imitation steak is a food product that is formed into a steak shape from various pieces of meat. Grilled fruits such as watermelon have been used as vegetarian steak alternatives. Exceptions, in which the me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
