Abstract

The aim of the study was to obtain the optimum content of chlorogenic acid (CA) yacon tubers on the use of natural inhibitors through a combination of immersion in natrium chloride, ascorbic acid and citric acid with 14 days storage at 5 and 15 Â° C temperature variations. Yacon tubers are obtained from the planting area of 1800 meters above sea level (mdpl) with harvest ages of 8 and 10 months. Data were analyzed through two-way Anova (Î± = 5%). The results of the study: The optimum content CA of 8 months harvest yacon tubers was 113.10 mg / L, through natural immersion of inhibitors NaCl, ascorbic acid and citric acid respectively at 5 ^oC storage temperature.
