Analysis of glycemic index, glycemic load and acceptability of enteral formulas based on tempeh flour and jicama flour as innovations for hyperglycemia patients
Low glycemic index formula are recommended for patients with hyperglycemia. Although tempeh and jicama flour contains fiber, arginine, glycine, inulin and alpha-linolenic acid that can be used as ingredients for enteral formulas of hyperglycemic patients, the evidence in reducing the glycemic index has not been proven. This study analyzed the differences of glycemic index (GI), glycemic load (GL) and acceptability of enteral formula based on tempeh flour and jicama flour for hyperglycemic patients. An experimental study with a completely randomized single factor design, by using the three ratios of tempeh flour to jicama flour A (2:3), B (1:1) and C (5:3). The glycemic index test used a one-shot case study model on 30 women selected. Acceptability test (hedonic test) was held on 30 semi-trained panelists. Data was analyzed using the Kruskal Wallis test, Mann Whitney, and independent t-test. The GI of formulas A, B and C were 101.15, 96.21 and 41.06. The GL of three formulas were 114, 86, and 41. Panelists like the color, flavor, and texture of formulas A, B and C, while the taste of the formula was considered to be neutral. The results showed there were significant differences between the GI and the flavor of formulas A and C (p = 0.002), (p = 0.011) and B and C (p = 0.013), (p = 0.036). There were no differences between color, flavor and texture of the formulas (p > 0.005). There are significant differences of the GI and the acceptability in taste attributes between formulas A, B and C. Formula C has the lowest GI and GL but requires improvement of taste attribute.
