天然物の起源
Stevioside is a naturally occurring sweetener (~200 times sweeter than sucrose) extracted from a South American plant, Stevia rebaudiana Bertoni. The dried leaves, the water extract of leaves, and the refined chemical ingredients, eg, and Rebaudioside A (~300 times sweeter than sucrose), can all be used as sweetening agents. These are collectively referred to as stevia. Discovered in Paraguay and Brazil, the plant was identified in the early 1970s as a plant of high economical value and transported to Japan for cultivation, where the commercialization of stevia leaves extract as a natural sweetener became a success. Today Stevia plant is cultivated primarily in China.
来歴
Because no food additive petition has been presented to the FDA, stevioside and related materials cannot be used in the United States as food ingredients. An import alert against stevia was issued by the FDA in 1991. In 1995, however, the FDA revised this import alert to allow the importation and use of stevia as a dietary supplement, but not as a sweetener or an ingredient for foods. In 2004, JECFA (Joint Expert Committee of Food Additives) issued a preliminary ADI (Allowed Daily Intake) of 2-mg/kg body weight (based on steviol) for stevia extract. This action may impact favorably on worldwide regulatory approval. As consumer’s demand on naturally sweetened products increases, interest in Stevia, and naturally occurring potent sweeteners in general, is expected to grow. A comprehensive review of stevia is available [Kinghorn, 2002].
使用
Stevioside is a glycoside from the stevia plant. Stevioside is a natural sweetening agent with sweetness about 250 times that of sugar with negligible effect on blood glucose. Stevioside, much like ot
her steviol glycoside is known for its application in treatment of many diseases like diabetes and high blood pressure. It is also used as a food additive and in dietary supplements.
利点
Stevioside may offer therapeutic benefits, as they have anti-hyperglycemic, anti-hypertensive, anti-inflammatory, anti-tumor, anti-diarrheal, diuretic, and immunomodulatory actions.
副作用
When taken by mouth: Certain chemicals in stevia, including stevioside and rebaudioside A, are likely safe when used as a food sweetener. Side effects might include bloating, nausea, dizziness, and numbness.
