Abstract
Inventia se refera la industria alimentara, si anume la procedeele de obtinere a substantelor edulcorante din stevie. Procedeul conform inventiei include extractia glicozidelor din stevia uscata cu apa la temperatura de 80...85 grade C, timp de 1,0...1,5 ore, pana la continutul fractiei masice de substante uscate de 8...10%. Extractul obtinut se trateaza cu acid ortofosforic sau cu acid citric la agitare pana la pH 3,0...3,4 la temperatura de 60...64 grade C, timp de o ora. Dupa filtrarea extractului se efectueaza tratarea lui cu oxid sau hidroxid de calciu la agitare la temperatura de 50...60(C, timp de o ora pana la pH 11,8...12,2. Extractul obtinut se filtreaza si se trateaza cu acid ortofosforic la temperatura de 20...30 grade C, timp de 2 ore pana la pH 8,2...9,0, se filtreaza, se neutralizeaza cu acid citric pana la pH 4,0...4,2 si se sterilizeaza. Pentru obtinerea extractului concentrat dupa neutralizarea cu acid citric pana la pH 4,0...4,2 se efectueaza racirea lui pana la temperatura de 2...6 grade C cu mentinerea timp de 2 zile, decantarea sedimentului si concentrarea extractului pana la continutul fractiei masice de substante uscate de 48...58%. Rezultatul inventiei consta in obtinerea extractului de stevie cu un inalt grad de purificare fara utilizarea solventilor organici. ŕThe invention relates to the food industry, namely to the processes for obtaining sweeteners from stevia. The process according to the invention includes the extraction of glycosides from dry stevia with water at a temperature of 80 ... 85 degrees C, for 1.0 ... 1.5 hours, until the content of the mass fraction of dry substances of 8 ... 10% . The extract obtained is treated with orthophosphoric acid or citric acid when stirred up to pH 3.0 ... 3.4 at 60 ... 64 degrees C for one hour. After filtering the extract, it is treated with calcium oxide or hydroxide while stirring at 50 ... 60 (C, for one hour up to pH 11.8 ... 12.2. The extract obtained is filtered and treated. with orthophosphoric acid at a temperature of 20 ... 30 degrees C, for 2 hours until pH 8.2 ... 9.0, filtered, neutralized with citric acid until pH 4.0 ... 4, 2 and sterilize In order to obtain the concentrated extract after neutralization with citric acid up to pH 4.0 ... 4.2, it is cooled to a temperature of 2 ... 6 degrees C and kept for 2 days, settling the sediment. and the concentration of the extract up to the content of the mass fraction of dry substances of 48 ... 58%. The result of the invention consists in obtaining the stevia extract with a high degree of purification without the use of organic solvents.
