Diabetes prevalence achieved 470B in 2021. Diabetics are looking for foods that allow them to better managethe postprandial glycemia. Owing to its large amylose fraction, pea starch may contribute to formulate recipes with a lowerglycemic index (GI). This study measured the rapidly, slowly digested and resistant fractions in pea starch and in a powdermix recipe. Starch fractions were determined according to the Englyst methodology. A nonblind repeat measure crossoverdesign trial in healthy humans was used to study the GI of pea starch and maltodextrin powder mix recipes against glucose. Gastrointestinal symptoms were measured. Thirteen healthy volunteers aged 18–60 years with body mass index <30 kg/m2 andfasting blood glucose <6.1 mmol/L participated in the study. They consumed 25 g available carbohydrate portions of the testproducts. Blood glucose was measured at -5 and 0 min before consumption till 180 min after starting to eat. The slowdigestible starch (SDS) content of native pea starch was 30% of the total starch content. The pea-based powder mix recipecontained 25% SDS in comparison with 9% for the maltodextrin-based recipe. The glucose response after pea starch wassignificantly lower compared with maltodextrin. The glucose response after pea starch recipe was significantly lower comparedwith maltodextrin recipe. There was no significant difference in mean scores for well-being and gastrointestinalsymptoms after consumption of pea starch and maltodextrin or between the two recipes. In conclusion, this study hasdemonstrated the presence of high SDS content in pea starch, which reduced postprandial glycemic response compared withmaltodextrin. The pea starch recipe did not induce any negative gastrointestinal symptoms. Pea starch may, therefore, prove tobe a beneficial ingredient in developing food products for improving glycemic control without undesirable side effects.

The resistant dextrin NUTRIOSE<SUP>®</SUP>, developed from starch, is expected to act as a prebiotic. The aim of this study was to determine the effects of NUTRIOSE<SUP>®</SUP> on cecal parameters, short-chain fatty acid (SCFA) concentrations, and fecal excretion in rats. In an initial experiment, twenty-four male Fischer F344 rats were randomly assigned to one of the following four treatments for 14 days: G0 (control diet), G2.5 (control diet + 2.5% of dextrin), G5 (control diet + 5% of dextrin), and G10 (control diet + 10% of dextrin). After 14 days, total cecal weight, cecal content, and cecal wall weight were significantly increased in G5 and G10 compared to G0. At the same time, cecal pH was significantly lower in G10 compared to G0. Total SCFA concentration was significantly higher in G10 than in G5, G2.5, and G0, and significantly higher in G5 than in G0. Acetate, butyrate, and propionate concentrations were significantly increased in G5 and G10 compared to the controls. In a second trial based on a similar design, eighteen male Fischer F344 rats were treated with a control diet supplemented with 5% of dextrin or 5% of fructo-oligosaccharide. The results obtained with NUTRIOSE<SUP>®</SUP> were similar to those obtained with the fructo-oligosaccharide. In a third experiment, two groups of 5 Fischer F344 rats were orally treated with 100 and 1,000 ㎎/㎏ NUTRIOSE<SUP>®</SUP>, respectively, and from 18% to 25% of the dextrin was excreted in the feces. The results of these three studies show that the consumption of NUTRIOSE<SUP>®</SUP>, by its effects on total cecal weight, cecal content, cecal wall weight, pH, and SCFA production, could induce healthy benefits since these effects are reported to be prebiotic effects.

The resistant dextrin NUTRIOSE$^{(R)}$, developed from starch, is expected to act as a prebiotic. The aim of this study was to determine the effects of NUTRIOSE$^{(R)}$ on cecal parameters, short-chain fatty acid (SCFA) concentrations, and fecal excretion in rats.
