Core Subject : Agriculture,
Indonesian Food and Nutrition Progress, is a primarily online, a peer-reviewed journal in food technology and nutrition. All papers should focus on the novelty of the research carried out. It is published by Indonesian Association of Food Technologists in collaboration with Faculty of Agricultural Technology, Gadjah Mada University. This journal is published two times a year which is a continuation of the last publication in 2005. The journal is devoted to a rapid peer reviewed full-length original research paper, short communications, and critical reviews, which serves as an international forum for the exchange of information in all aspects of food technology and nutrition. Food and Nutrition Progress includes a wide range of food technology and nutrition topics such as: Physical, chemical, biotechnological, microbiological, process engineering, analytical, and nutritional aspects; Post-harvest technology; Sensory evaluation; Diet plans; Gastronomy; Food safety and hygiene; Functional foods; Novel foods.

Abstract

Gembolo (Dioscorea bulbifera bulbils) is a tuber that can be used as an alternative carbohydrate source. This tuber contains various essential minerals and vitamins; it also has a starch content of 6.627% and an amylose content of 30.63%. Research into gembolo has been limited to its physical and chemical characterization and its nutritional content. Using gembolo starch as a source of type RS3 via the autoclaving-cooling method has not yet been studied. RS3 promotes digestive and metabolic health by functioning as a type of fiber. Using gembolo starch as a source of type RS3 via the autoclaving-cooling method has not yet been studied. RS3 promotes digesti ve and metabolic health by functioning as a type of fiber. The cycle frequency used consisted of 1 to 5 autoclaving-cooling cycles. The analysis of the physicochemical properties included the following: RS, starch, amylose, amylopectin, water content, granule morphology, pasting properties, and water-holding capacity (WHC) and oil-holding capacity (OHC). After modification of gembolo starch with 1-5 autoclaving-cooling cycles, there was a 4.49% decrease in water content and a 9.65% decrease in starch content. There was also a 8.56% decrease in amylose content and a 33.29% increase in RS content. An increase in WHC of 144.22%, an increase in OHC of 2.91%, and a decrease in the pasting profile of 7753 cP. Based on these data, the treatment of 5 autoclaving-cooling cycles produced the highest RS of 74%. From this research, gembolo can be a potential source of functional RS3 starch.
