Reducer of glycemic index in rice (ROGER): A novel device to reduce the glycemic index in rice for diabetic patient

摘要

Globally in 2010, the prevalence of patient with diabetes mellitus (DM) in 20-79 years old is 6.4% (285 million) and will increase until 7.7% (439 million) in 2030. DM is a disease characterized by hyperglycemia due to abnormality insulin secretion, insulin action, or both. If it uncontrolled can causes complications such as retinopathy, nephropathy, and neuropathy. The one of prevention for DM complication is lifestyle modification, such as setting the amount of glucose intake. Carbohydrate is thought as the highest glucose content, it's about 74% of the total composition. Carbohydrate contains SR (starch resistant) that include amylose lipid 1, the substance which can melt at <100°C and amylose lipid 2, the substance which can melt at >100°C. Therefore, we made an innovation of making carbohydrate in a low level of glucose and we called it ROGER (Reducer Glycemic Index in Rice). The process of making ROGER starts from March until July 2018 in the laboratory of mechanical engineering faculty, chemical laboratory, and hospital of PKU Muhammadiyah. The method used in this process is Kaizen, Usability method, Luff Scholer method, and quasi-experiments. Basically, ROGER was made from two kinds of instruments there are centrifuge and heater. The result was 5 minutes to reached the appropriate rice, while the centrifuge speeds were 9000 rpm. To know the result, we have to do the identification test of glucose level by using Luff-Scholer method. The result of conventional rice were water content (65.48%) and glucose levels (1.22%). While in the treatment group using ROGER rice obtained water content (66.04%) and glucose levels (0.03%). After that, we did the test in uncomplicated diabetes mellitus type-2 patients. The comparison of in-time blood glucose and two-hour post-prandial on patient 1 (P1), P2, P3, P4, and P5 used ROGER's rice are 116 to 108, 172 to 79, 221 to 215, 173 to 167, and 93 to 91 (P>0.05; n = 5).
