PURPOSE:To obtain a sweetener with mellow taste, free from the offensive taste inherent in stevioside by drying, grinding and boiling matured stevia leaves and by aging the resultant concentrate. CONSTITUTION:Matured stevia leaves are dried and ground into powder <=10mu in mean particle size, which is then boiled into a stevia concentrate. This concentrate is then aged to obtain the objective stevia sweet concentrate. The present concentrate, when obtained through multi-step concentration process, will result in a sweetener of higher quality. Furthermore, aging at 15-30 deg.C for 90-360 days will result in a sweetener of mellower taste. Stevia, which is a perennial plant classified as Compositae, native to Paraguay and Brazil, South America, and scientifically named as Stevia, Rebaudiana, Bertoni, has also been widely cultivated in Japan in recent years. |
