Optimasi Metoda Kristalisasi Steviosida Berbasis Air dari Stevia rebaudiana (Bert.) Penggunaan Remitan Buruh Migran dan Pertambahan Aset Rumah Tangga

Stevioside is compound that can be extracted from the Stevia rebaudiana (Bert.). The steviol glycoside of stevoside have potential, functions, and characteristics of the sweetener that is larger than other types of sweeteners. During this time, the constraints faced by the methods used have not been effective and small solubility in water solvent. The purposes of this experiment were to optimize the crystallization method of stevioside, to indentify stevioside in crystall, to determine the content of stevioside by using High Performance Liquid Chromatography (HPLC), and to determine organoleptic assay by hedonic test from crystall formulated. Based on research obtained the percent yield of each sample was 3,27%, 1,23% (w/w) in stevioside crystall form, then 3,24%, 4,48%, 6,99% (w/w) in stevioside isolate form. The results obtained by qualitative analysis showed the all sample were positive for stevioside. The stevioside was lost in the drying assay were 0,00%, 8,00%, 20,00%, 17,00%, 15,00% (w/w) of the initial mass. The test with anthrone reagent showed positive results with the green color shown. The content of stevioside in sample 1, 2, 3, 4, 5 were 45,99%, 93,17%, 0,76%, 75,39%, 6,65% (w/w), respectively. The method developed can be used for stevioside crystallization.
