Stevioside
Stevioside is a glycoside derived from the stevia plant, which can be used as a sweetener. Evidence of benefit is lacking for long-term effects on weight loss and heart disease risks. Origin Stevioside is the main sweetener (along with rebaudioside A) found in the leaves of ''Stevia rebaudiana'', a plant originating in South America. Dried leaves, as well as aqueous extracts, have been used for decades as a sweetener in many countries, notably in Latin America and Asia (Japan, China). Stevioside was discovered in 1931 by French chemists who gave it its name. The sweetening power of stevioside was estimated to be about 300 times stronger than cane sugar. Safety Since 2008, the U.S. Food and Drug Administration has not objected to the use of stevia extracts and some purified steviosides, mainly stevioside and rebaudioside, as generally recognized as safe, GRAS for use as an ingredient in manufactured foods.

Steviol Glycoside
Steviol glycosides are the chemical compounds responsible for the sweet taste of the leaves of the South American plant ''Stevia rebaudiana'' (Asteraceae) and the main ingredients (or chemical precursor, precursors) of many sugar substitute, sweeteners marketed under the generic name stevia and several trade names. They also occur in the related species ''Stevia phlebophylla, S. phlebophylla'' (but in no other species of ''Stevia (genus), Stevia'') and in the plant ''Rubus chingii'' (Rosaceae). Steviol glycosides from ''Stevia rebaudiana'' have been reported to be between 30 and 320 times sweeter than sucrose, although there is some disagreement in the technical literature about these numbers. They are heat-stable, pH-stable, and do not fermentation, ferment.

Stevia
Stevia () is a sweet sugar substitute that is about 50 to 300 times sweetness, sweeter than sugar. It is extracted from the leaves of ''Stevia rebaudiana'', a plant native to areas of Paraguay and Brazil. The active compounds in stevia are steviol glycosides (mainly stevioside and rebaudioside). Stevia is heat-stable, pH-stable, and not fermentation (food), fermentable. Humans cannot metabolize the glycosides in stevia, and it therefore has zero calories. Its taste has a slower onset and longer duration than that of sugar, and at high concentrations some of its extracts may have an aftertaste described as licorice-like or Bitter taste, bitter. Stevia is used in sugar-reduced and calorie-reduced food and beverage products as an alternative for variants with sugar. The legal status of stevia as a food additive or dietary supplement varies from country to country. In the United States, certain high-purity ''stevia glycoside'' extracts have been generally recognized as safe (GRA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rebaudioside A
Rebaudioside A (sometimes shortened to "Reb A") is a steviol glycoside from the leaves of ''Stevia rebaudiana'' that is 240 times sweeter than sugar. Rebaudioside A is the sweetest and most stable steviol glycoside, and is less bitter than stevioside. ''Stevia'' leaves contain 9.1% stevioside and 3.8% rebaudioside A. The glycoside contains only glucose (to the exclusion of other commonly found monosaccharides) as its monosaccharide moieties. It contains four glucose molecules in total with the central glucose of the triplet connected to the main steviol structure at its hydroxyl group, and the remaining glucose at its carboxyl group forming an ester In chemistry, an ester is a compound derived from an acid (either organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group () of that acid is replaced by an organyl group (R). These compounds contain a distin ... bond. References Glucosides Vinylidene compounds {{Carbohydrate-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzymatic, enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of ''Heliconius'' butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body. In formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an ''O-glycoside''), N- (a ''glycosylamine''), S-(a ''thioglycoside''), or C- (a ''C-glycoside'') glycosidic bond. Accord ...

Weight Loss
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue). Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or increase in exercise is called cachexia and may be a symptom of a serious medical condition. Intentional Intentional weight loss is the loss of total body mass as a result of efforts to improve physical fitness, fitness and health, or to change Human physical appearance, appearance through slimming.

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 ...

Glucosides
A glucoside is a glycoside that is chemically derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is Hydrolysis, hydrolysed by purely chemical means, or decomposed by fermentation (biochemistry), fermentation or enzymes. The name was originally given to plant products of this nature, in which the other part of the molecule was, in the greater number of cases, an aromatic aldehydic or natural phenol, phenolic compound (exceptions are sinigrin, Jinigrin and Jalapin or Scammonin I, Scammonin). It has now been extended to include synthetic ethers, such as those obtained by acting on ethanol, alcoholic glucose solutions with hydrochloric acid, and also the polysaccharoses, e.g. cane sugar, which appear to be ethers also. Although glucose is the most common sugar present in glucosides, many are known which yield rhamnose or iso-dulcite; these may be termed pentosides. Much attention has been given to the non-sugar parts (agly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
