Monosodium Glutamate
Monosodium glutamate (MSG), also known as sodium glutamate, is a sodium salt of glutamic acid. MSG is found naturally in some foods including tomatoes and cheese in this glutamic acid form. MSG is used in cooking as a flavor enhancer with a savory taste that intensifies the umami flavor of food, as naturally occurring glutamate does in foods such as stews and meat soups. MSG was first prepared in 1908 by Japanese biochemist Kikunae Ikeda, who tried to isolate and duplicate the savory taste of ''kombu'', an edible seaweed used as a broth ('' dashi'') for Japanese cuisine. MSG balances, blends, and rounds the perception of other tastes. MSG, along with disodium ribonucleotides, is commonly used and found in stock (bouillon) cubes, soups, ramen, gravy, stews, condiments, savory snacks, etc. The U.S. Food and Drug Administration has given MSG its generally recognized as safe (GRAS) designation. It is a popular misconception that MSG can cause headaches and other feelings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium
Sodium is a chemical element; it has Symbol (chemistry), symbol Na (from Neo-Latin ) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 element, group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the Abundance of elements in Earth's crust, sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been Leaching (chemistry), leached by the action of water from the Earth, Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in Soap, soap manufac ...

Disodium Ribonucleotides
Disodium 5'-ribonucleotides or I+G, E number E635, is a flavor enhancer which is synergistic with glutamates in creating the taste of umami. It is a mixture of disodium inosinate (IMP) and disodium guanylate (GMP) and is often used where a food already contains natural glutamates (as in meat extract) or added monosodium glutamate (MSG). It is primarily used in flavored noodles, snack foods, chips, crackers, sauces and fast foods. It is produced by combining the sodium salts of the natural compounds guanylic acid (E626) and inosinic acid (E630). A mixture composed of 98% monosodium glutamate and 2% E635 has four times the flavor enhancing power of monosodium glutamate (MSG) alone. Side effects and safety Disodium 5'-ribonucleotides were first assessed in 1974 by the Joint FAO/WHO Expert Committee on Food Additives based on all available scientific literature. This assessment resulted in a new specification prepared and an "ADI Not Specified". This essentially means that this add ...

Blinded Study
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints. During the course of an experiment, a participant becomes unblinded if they deduce or otherwise obtain information that has been masked to them. For example, a patient who experiences a side effect may correc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Restaurant Syndrome
Glutamate flavoring is the generic name for flavor enhancer, flavor-enhancing compounds based on glutamic acid and its salt (chemistry), salts (glutamates). These compounds provide a savory taste to food. Glutamic acid and glutamates are natural constituents of many fermentation (food), fermented or aged foods, including soy sauce, fermented bean paste, and cheese. They can also be found in hydrolyzed proteins such as yeast extract. The sodium salt of glutamic acid, monosodium glutamate (MSG), is manufactured on a large scale and widely used in the food industry. Glutamic acid versus glutamates When glutamic acid or any of its salts are dissolved in water, they form a Solution (chemistry), solution of separate anion, negative ions, called glutamates, and positive ions like hydronium, or sodium, . The result is actually a chemical equilibrium among several ionized forms, including zwitterions, that depends on the pH (acidity) of the solution. Within the common pH range of fo ...

Headaches
A headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. There is an increased risk of depression in those with severe headaches. Headaches can occur as a result of many conditions. There are a number of different classification systems for headaches. The most well-recognized is that of the International Headache Society, which classifies it into more than 150 types of primary and secondary headaches. Causes of headaches may include dehydration; fatigue; sleep deprivation; stress; the effects of medications (overuse) and recreational drugs, including withdrawal; viral infections; loud noises; head injury; rapid ingestion of a very cold food or beverage; and dental or sinus issues (such as sinusitis). Treatment of a headache depends on the underlying cause, but commonly involves pain medication (especially in case of migraine or cluster headaches). A headache is one ...

Generally Recognized As Safe
Generally recognized as safe (GRAS) is a United States Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts under the conditions of its intended use. An ingredient with a GRAS designation is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. The concept of food additives being "generally recognized as safe" was first described in the Food Additives Amendment of 1958, and all additives introduced after this time had to be evaluated by new standards. Some examples of substances recognized as GRAS include ascorbic acid (vitamin C), citric acid, and salt, which are all commonly used in food preservation and flavoring. The FDA list of GRAS notices is updated approximately each month, as of 2021. History On 6 September 1958, the Food Additives Amendment of 1958 was signed into law, with a list of 700 food substances that were exempt from the then-new requirement ...

Condiment
A condiment is a preparation that is added to food, typically after cooking, to enhance the Flavoring, flavour, to complement the dish or to impart a specific flavor. Such specific flavors generally add sweetness or pungency, or sharp or piquant flavors. The seasonings and spices common in many different cuisine arise from global introductions of foreign trade. Condiments include those added to cooking to impart flavor, such as barbecue sauce and soy sauce, those added before serving such as mayonnaise in a sandwich, and those added tableside to taste, such as ketchup with fast food. Condiments can also provide other health benefits to diets that lack micronutrients. Definition The exact definition of a condiment varies. Some definitions encompass spices and herbs, including salt and pepper, using the term interchangeably with ''seasoning''. Others restrict the definition to include only "prepared food compound[s], containing one or more spices", which are added to food after th ...

Gravy
Gravy is a sauce made from the juices of meats and vegetables that run naturally during cooking and often thickened with thickeners for added texture. The gravy may be further coloured and flavoured with gravy salt (a mix of salt and caramel food colouring) or gravy browning (gravy salt dissolved in water) or bouillon cubes. Powders can be used as a substitute for natural meat or vegetable extracts. Canned and instant gravies are also available. Gravy is commonly served with roasts, meatloaf, sandwiches, rice, noodles, fries (chips), mashed potatoes, or biscuits (North America, see biscuits and gravy). History One of the earliest recorded mentions of gravy is in a British recipe book entitled " The Forme of Cury", dating from the 14th century. The term gravy originates from the Old French word for meat or fish bouillon, which in fourteenth century French manuscripts was "gravé" or "grané". It is suggested that the French word grané is associated with grain, connect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
