Stevia extract powder introduction

Stevia extract is a substance extracted from the leaves of Stevia rebaudiana, a compositae plant. The main active ingredient is stevioside. Stevia glycoside is used as a sweetener, which has the effects of lowering blood sugar, lowering blood pressure, promoting metabolism, and treating excessive gastric acid.

Stevia is native to Paraguay and Brazil in South America. It was used by Paraguayan residents to make sweet tea more than 400 years ago. Stevia rebaudiana was named by Botanist Bertoni in 1905 and has been used since. In 1955, the experiment of artificial nursery cultivation was started. In 1964, Enrigue de Gasperin of Paraguay succeeded in transplanting and domesticating stevia in the field. At the end of the 1960s, this plant was valued by many countries and regions. Japan, Singapore, Malaysia, South Korea, Israel and China have a large amount of cultivation. Japan has attached great importance to stevioside since banning cyclamate in 1969. However, due to its incomplete toxicological and metabolic data, stevioside is only approved for use in 8 countries in the world, including China, Japan, South Korea, Brazil, Paraguay, Thailand and Malaysia. The ADI value of stevioside is 5.5mg/kg. As of 2000, it has not been approved by European and American countries. In the past 10 years, FDA has refused to approve its status as a food additive for three times. However, on September 18, 1995, FDA approved it as a "dietary supplement" for sale and consumption.
