Stevia
Stevia () is a natural sweetener and sugar substitute derived from the leaves of the plant species ''Stevia rebaudiana'', native to Paraguay and Brazil. The active compounds are steviol glycosides (mainly stevioside and rebaudioside), which have about 50 to 300 times the sweetness of sugar, are heat-stable, pH-stable, and not fermentable. The human body does not metabolize the glycosides in stevia, so it contains zero calories as a non-nutritive sweetener. Stevia's 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. Stevia is used in sugar- 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, high-purity ''stevia glycoside'' extracts have been generally recognized as safe (GRAS) since 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stevia Rebaudiana
''Stevia rebaudiana'' is a plant species in the genus '' Stevia'' of the family Asteraceae. It is commonly known as candyleaf, sweetleaf or sugarleaf. It is a small seasonal plant which grows to a height of . It has elongated leaves that grow along the stems and are lined up against each other. The flowers are typically trimmed to improve the taste of the leaves. Stevia is a tender perennial native to parts of Brazil and Paraguay having humid, wet environments. Stevia is widely grown for its leaves, from which extracts can be manufactured as sweetener products known generically as stevia and sold under various trade names. The chemical compounds that produce its sweetness are various steviol glycosides (mainly stevioside and rebaudioside), which have 200–300 times the sweetness of sugar. Stevia leaves contain 9.1% stevioside and 3.8% rebaudioside A. Description The flowers are white with light purple accents and no fragrance. Plants produce fruit which is ribbed spindle-sh ...

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 precursors) of many sweeteners marketed under the generic name stevia and several trade names. They also occur in the related species '' S. phlebophylla'' (but in no other species of ''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 ferment. Steviol glycosides do not induce a glycemic response when ingested, because humans cannot metabolize stevia. The acceptable daily intake (ADI) for steviol glycosides, expressed as steviol equivalents, has been established to be 4 mg/kg body weight/day, and is based on no observed effects of a 100 fol ...

Non-nutritive Sweetener
A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie () or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant extracts or processed by chemical synthesis. Sugar substitute products are commercially available in various forms, such as small pills, powders, and packets. In North America, common sugar substitutes include aspartame, monk fruit extract, saccharin, sucralose, and stevia; cyclamate is also used outside the United States. These sweeteners are a fundamental ingredient in diet drinks to sweeten them without adding calories. Additionally, sugar alcohols such as erythritol, xylitol, and sorbitol are derived from sugars. Approved artificial sweeteners do not cause cancer. Reviews and dietetic professionals have concluded that moderate use of non-nutritive sweeteners as a safe replacement for sugars can he ...

Pedro Jaime Esteve
Pedro Jaime Esteve (''latinicized: Estevius, Catalan: Pere Jaume Esteve''; c. 1500 in Sant Mateu del Maestrat – 1556 in Valencia) was a Spanish doctor, botanist, and humanist. Life and work Pedro Jaime Esteve studied in Valencia, Paris, and Montpellier. Later, he worked as a professor of medicine and mathematics at the University of Valencia. In 1551, he published the Hippocratic work "Epidemics II" in Greek, with numerous illustrations and a Latin translation. This book was the medical foundation of humanism in Spain. In 1552, he published a critical edition of "Theriaca", a work on the poisons and bites of snakes and scorpions, by the ancient Greek doctor Nicander of Colophon. He made his Latin hexameter version available with Latin and Catalan nomenclature and taxonomy of some plants from the region of Valencia. Later, Esteve wrote a volume on medicinal herbs, which, however, has been lost. Notes The American plant genus ''Stevia Stevia () is a natural sweetener and ...

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.

Moisés Santiago Bertoni
Mosè Giacomo Bertoni (15 June 1857 – 19 September 1929), known in Spanish as Moisés Santiago Bertoni, was an Italian-speaking Swiss naturalist. He emigrated to South America in 1884 and lived in Paraguay from 1887 until he died in 1929. Bertoni work and researched in botany, meteorology, and anthropology. He discovered and classified many new species of plants and left a collection of more than 7000 vegetal species and about 6500 insects. One of the plants he studied in depth was ''ka'a he'ê'' (''Stevia rebaudiana''), a herb indigenous to Paraguay, which became important as a non-caloric sweetener, reputed to be 300 times sweeter than sugar. He also scientifically classified yerba mate (''Ilex paraguariensis''). Childhood and youth He was born in the small village of Lottigna, in canton Ticino in the Italian-speaking region in Switzerland, on June 15, 1857, the son of Ambrose Bertoni, a lawyer, jurist, and official, and Josefina Torreani, a teacher from Milan.

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 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. According to th ...
