Applications ofStevia rebaudiana in Agriculture andStockbreedingJBB STEVIALABORATORY/B&LcorporationShintaro Kimura
Overview of Stevia Applications in Japan◇1970：Stevia rebaudiana introduced to Japan → Trial cultivation started Stevioside production◇1975：Mr. N. Sato, JBB President, focused by on big potentials of Stevia rebaudiana for non-sweetener applications Sweetener makers◇1982：He started research on Stevia r. → production of Stevia hot-water fermented extract R&D and commercialization for◇1988：He established JBB Stevia Laboratory B&L JBB → studied effect-efficacy of Stevia r., Agriculture and commercialized Stevia products Stockbreeding Echo for many applications Stevia Extract◇2005：B&L Corporation was Fishery & Powder Pets incorporated for further expansion of Stevia Forestry Health potentialities.
