AbstractEight commonly cultivated and consumed rice varieties of Northern Himalayan regions and a popular high amylose rice variety were characterized at Wx locus and evaluated for resistant starch (RS), in-vitro starch digestibility, predicted glycemic index (pGI), glycemic load (GL) and textural parameters. Cytosine and thymine repeats (CT)n at waxy locus (Wx) showed high association with apparent amylose content (AAC). Both pGI and GL varied substantially within the selected varieties. The pGI was relatively lower in high and intermediate amylose Indica varieties compared to low amylose Japonica ones. However, Koshikari despite being a low amylose variety showed relatively lower pGI and GL, due to its higher RS, dietary fiber, protein and fat content. It was thus presumed that in addition to AAC, RS and other grain components also affect the glycemic response. Inherent resistance to enzymatic hydrolysis was also found to be higher in firm textured and less sticky rice varieties. The genotypes—Lalat, Basmati-1509 and Koshikari, in view of their low to moderate pGI and relatively higher RS content, can be explored in future breeding programmes to develop rice varieties whose consumption will help to prevent hyper/hypo glycemic responses in Northern Himalayan regions, where daily staple diet is rice.

Estimated Glycemic Index

This study aimed to evaluate the influence of sourdough fermentation on the estimated glycemic index (eGI), in vitro starch digestibility, and textural and sensory properties of eight experimentally prepared sourdough breads. Wheat and whole wheat flour bread samples were produced under different fermentation conditions (25 °C and 30 °C) and fermentation methods (type-1 and type-2). In type-1 fermentation, sourdough was obtained via spontaneous fermentation. Indigenous strains (Lactobacillus brevis ELB99, Lactiplantibacillus plantarum ELB75, and Saccharomyces cerevisiae TGM55) were used for type-2 fermentation. Fermentation type and temperature significantly affected eGI, the hydrolysis index (HI), the starch fraction, and the textural properties of the samples (p < 0.05). The resistant starch (RS) content increased after fermentation, while rapidly digestible starch (RDS), HI, and eGI decreased. RS values were significantly higher in type-2 than in type-1 at the same temperature for both flour types (p < 0.05). At 25 °C, RS values were higher in both fermentation types. In the white flour samples, eGI values were in the range of 60.8–78.94 and 62.10–78.94 for type-1 and type-2, respectively. The effect of fermentation type on eGI was insignificant (p < 0.05). In the whole flour samples, fermentation type and temperature significantly affected eGI (p < 0.05). The greatest eGI decreases were in whole wheat sourdough bread at 30 °C using type-2 (29.74%). The 30 °C and type-2 samples showed lower hardness and higher specific volume. This study suggests that fermentation type and temperature could affect the eGI and the textural and sensory properties of sourdough bread, and these factors should be considered during bread production. The findings also support the consumption of wheat and whole wheat breads produced by type-2 fermentation due to higher RS and slowly digestible starch (SDS) and lower RDS and eGI values.

Dietary fiber content (as non-starch polysaccharides, NSP) and in vitro starch digestibility of legumes (beans, lentils, chickpeas and peas) present in the Spanish diet were determined. Raw, boiled and industrially processed legumes were analyzed, as well as legume dishes prepared according to tradi tional recipes or commercial canned meals. A reduction of total NSP was observed in cooked prepa rations probably due to the presence of other food ingredients. Soluble NSP increased in industrially processed legumes at the expense of the insoluble fraction. Significant amounts of resistant starch (RS) were detected in processed legumes. Industrial processing seemed to result in an increased in vitro starch digestibility with a higher starch digestion rate index (SDRI) in comparison with domes tic processing. Rapidly available glucose (RAG) in processed legumes, as a predictor of their poten tial glycemic response, showed differences depending on the type of legume and treatment. Gener ally pulses consumed as home-made meals had lower RAG values.

Slowly Digestible Starch

Abstract: The objective of this work was to develop gluten-free cookies and savory fried pies using tannin-rich sorghum (Sorghum bicolor) flour, to evaluate their in vitro starch digestibility, and to verify how knowledge of sorghum benefits may contribute to the sensory acceptability of both products. The contents of rapidly digestible starch, slowly digestible starch, and resistant starch were determined. Sensory acceptance was evaluated in two sessions: one without information on sorghum benefits to human health; and another where this information was presented. The resistant starch and slowly digestible starch contents of the cookies (5.07 and 16.22%, respectively) were about twice those of the savory fried pies (2.54 and 8.89%, respectively), whereas the opposite was observed for the rapidly digestible starch contents (9.89 and 19.65%, respectively). The cookies and savory fried pies were sensorially accepted, with a significant increase in the means of the sensory scores after the information on sorghum benefits was disclosed. Therefore, gluten-free cookies and savory fried pies prepared with tannin sorghum flour have a great commercial potential, shown by the good sensory acceptance and by the slowly digestible starch and resistant starch contents of these products.
