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.

ABSTRACTTapioca flour is derived from the starch extracted from manioc and is a widely used food product in Brazil. Rice flour is produced from grains of rice and is used in the production of bread, porridge, cakes and cookies, which are recommended for people with celiac disease. The goal of this work was to add value to the aforementioned products by developing cookies based on tapioca and rice flours. Five formulations were prepared: A 100:0, B 75:25, C 50:50, D 25:75 and E 0:100 to tapioca and rice flour respectively, with the addition of brown sugar, and analyses its technological, nutritional and sensory properties. The following physical, physicochemical and nutritional properties were analyzed: dough texture profile, cookie weight, diameter and volume, acidity, water activity, carbohydrates, lipids, proteins, dietary fiber, ash content and moisture. A sensory evaluation was held using an affective test with 90 judges and a structured nine-point hedonic scale ranging from 'like extremely' to 'dislike extremely' for the attributes scent, color, texture, taste and overall impression in addition to purchase intent. The results indicate that cookies made of tapioca and rice flours with the addition of brown sugar have technological, physicochemical and nutritional profiles within legal standards; however, the fiber contents were below recommendations. The sensory evaluation showed good acceptance of the cookies, with average scores above 7.0. This study is part of an attempt to raise further discussions regarding the production of new low-cost bakery products that are nutritionally enriched, viable and easily accessible to all, including to people with celiac disease.

The use of wholemeal flour and sourdough fermentation in different food matrices has received considerable attention in recent years due to its resulting health benefits. In this study, a semolina-based and a wholemeal semolina-based sourdough were prepared and added to the formulation of gnocchetti-type fresh pasta. Four types of gnocchetti were made, using semolina plus semolina-based sourdough (SS), semolina plus wholemeal semolina-based sourdough (SWS), semolina alone (S), and semolina plus wholemeal semolina (WS). The latter two were used as controls. The digestibility of starch was studied both in vitro and in vivo, and the glycemic response (GR) and glycemic load (GL) were determined. Starch digestibility, both in vivo and in vitro, was higher in wholemeal semolina than semolina pasta and the resulting GR values (mg dL−1 min−1) were also higher (2209 and 2277 for WS and SWS; 1584 and 1553 for S and SS, respectively). The use of sourdough significantly reduced the rapidly digestible starch (RDS) content and increased the inaccessible digestible starch (IDS) content. The addition of sourdough to the formulation had no effect on the GR values, but led to a reduction of the GL of the pasta. These are the first data on the GR and GL of fresh pasta made with sourdough.

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.

Gluten-free pasta enriched with fish can support a nutritive and suitable option for people with celiac disease that allows achieving the benefits of fish consumption, especially the consumption of Ω-3 fatty acids; however, this requires that the pasta has adequate technological and sensory properties. For this purpose, four optimal formulations, obtained with an iterative process, were analyzed to determine the effect of the different ingredients (yellow corn flour, white corn flour, and rice flour) in gluten-free pasta compared to commercial wheat pasta. An evaluation of the color, texture, and technological properties were conducted, and the pasta was sensorially characterized. The enriched gluten-free pasta required shorter cooking times (≈3 min) and was characterized by lower hardness, springiness, gumminess, chewiness, and fracturability, and had higher values of adhesiveness than wheat pasta. In addition, the incorporation of yellow corn gives gluten-free pasta a similarity in color to commercial pasta, with a value of ∆E between 5.5 and 8.0. Regarding the sensory analysis, gluten-free pasta was characterized by slight fishy aromas and flavors with some aftertaste compared to commercial pasta. Finally, the use of different cereals to obtain gluten-free pasta could be a good and feasible alternative despite the technological and sensory modifications observed.
