THE EFFECT OF YAKON TUBER PREBIOTIC SYRUP ON DIGESTIVE ENZYME ACTIVITY IN DUODENUM Rattus norvegicus
Abstract
Prebiotics are compounds that cannot be digested by digestive enzymes and can stimulate the growth of probiotics. Fructooligosaccharides are the most commonly used prebiotics. The purpose of this study was to determine the effect of giving prebiotic syrup of yakon tuber to the activity of amylase, protease, and lipase enzymes in the duodenum of Rattus norvegicus. The samples of this research were yakon tubers from the Wonosobo area and the experimental animal Rattus norvegicus. Experimental animals were divided into 4 groups. The group that was fed with water supplements (P0 = negative control), prebiotic syrup of yakon tuber S0 (P1), prebiotic syrup of yakon tuber S1 (P2), and commercial FOS (P3). Determination of enzyme activity of amylase, lipase, and protease using UV-Vis spectrophotometer instrument. Statistical analysis used was ANOVA and Post Hoc = LSD. The results showed that the administration of prebiotic syrup of yakon tubers S1 could significantly increase the activity of amylase, lipase and protease enzymes (P < 0.05). In the provision of prebiotic syrup of yacon tubers S0 can increase the activity of amylase and protease enzymes, while the lipase enzyme has no significant effect.
Key words: yakon tuber prebiotic syrup, amylase, protease, lipase
