Twenty-five percent of steamed millet flour (MF) and different contents of dietary fiber (DF) were added to wheat flour (WF). The results showed that 25% of steamed MF and DF had significant effects (p < 0.05) on dough farinographical and tensile properties. With the increase of DF content, the hardness of the steamed bread increased, the elasticity decreased significantly, and the sensory acceptability decreased. The results of digestion showed that the content of rapidly digested starch (RDS) and slowly digested starch (SDS) in MF steamed bread decreased with the increase of DF, while resistant starch (RS) increased. Meanwhile, the starch hydrolysis rate, hydrolysis index (HI), and glycemic index (GI) decreased significantly (p < 0.05), and protein digestibility decreased gradually. Comprehensive evaluation showed that the 2% DF sample had good sensory performance and medium GI, which is beneficial to the control of blood sugar levels. These good functional properties could meet the requirements of a healthy diet.

Diabetes mellitus is directly related to diet and lifestyle. Control of blood glucose levels is needed to reduce the risk of complications, and one way is to choose foods with a low glycemic index. Cookies made from tempeh gembus/tempeh gembus flour are expected to be eaten as a snack and are safe for people with diabetes. The aim of this research was to analyze glycemic index (GI), glycemic load (GL), dietary fiber, in vitro starch, and protein digestibility of cookies with tempeh gembus flour substitution. Completely randomized design research with one primary factor used cookies with variations of 0%, 25%, and 50% tempeh gembus flour substitution. GI was calculated using the Incremental Area Under the Blood Glucose Response Curve (IAUC) method. Dietary fiber concentration analysis was done by enzymatic methods. The starch and protein digestion rates were calculated using the in vitro method. GI, GL, dietary fiber, starch digestion rate, and protein digestion rate data were analyzed with descriptive methods. Cookies with lowest GI (47.01 ± 11.08%) and GL (6.90 ± 1.63) were found in cookies with 50% tempeh gembus flour substitution. The highest dietary fiber content (24.61 ± 0.41%), digestibility of starch (48.07 ± 0.01%), and protein (20.27 ± 0.43%) cookies were found in cookies with 50% tempeh gembus flour substitution. The higher tempeh gembus flour substitution produced low GI and GL while its dietary fiber, in vitro starch, and protein digestibility were highest.

Glycemic Profile

This study aimed to perform a systematic review and meta-analysis of the glycemic index (GI) of gluten-free bread (GFB) and its main ingredients. The systematic review followed PRISMA guidelines, using seven electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, gray literature research with Google Scholar, and patents with Google Patent tool), from inception to November 2020. Eighteen studies met the inclusion criteria evaluating 132 GFB samples. Five articles tested GI in vivo, eleven in vitro; and two studies tested both methods. The analysis showed that 60.7% (95% CI: 40.2–78.1%) of the samples presented high glycemic indexes, evidencing a high glycemic profile for GFB. Only 18.2% (95% CI: 11.7–27.2%) of the bread samples presented in the studies were classified as a low GI. Meta-analysis presented moderate/low heterogenicity between studies (I2 = 61% and <1% for both high and low GIs) and reinforced the proportion of high GIs. Lower GIs were found in formulations based on Colocasia esculenta flour or enriched with fiber, yogurt and curd cheese, sourdough, psyllium, hydrocolloids, enzymes, fructans, and resistant starch, highlighting the efficacy of these ingredients to lower GFBs’ GI. GFB tends to present high GI, impacting the development of chronic diseases when consumed.

<p>Various levels of bambara groundnut protein cocnentrate ranging from 0 to 15% were used in the formulation of plantain paste (Amala) and plantain baked products. ‘Amala’ and cookies were produced from 85% plantain flour and 15% bamabara groundnut protein concentrate, while cakes and bread were produced from 70% wheat flour, 20% plantain flour and 10% bambara groundnut protein concentrate. Starch fractions and <em>in vitro</em> starch hydrolysis of the products were determined. The lowest total starch value was found in plantain flour (51.51%) and highest in cakes (70.62%). There was no significant difference in resistant starch between plantain flour and ‘amala’ (5.22% and 4.99%, respectively). The lowest resistant starch was observed in bread (0.94%), while digestible starch was higher in bread and cakes compared to plantain flour. Higher total starch also resulted in higher digestible starch. The kinetic constant of plantain products showed very low values suggesting generally, higher resistance to enzymatic hydrolysis. The highest hydrolysis index (HI) of 74.85%, and 74.25% were observed in cakes and bread, respectively; which also resulted in higher predicted glycemic index (PGI) of 80.79% (Cakes) and 80.45% (Bread). These values were significantly different from that obtained for ‘amala’ with H1 of 56.40% with a corresponding PGI of 70.67% while cookies recorded HI value of 62.64% and PGI of 74.10%. The lowest HI (53.98%) and PGI (69.35%) was observed in plantain flour. This study showed that the more plantain flour in the product formualtions, the lower the hydrolysis index (HI) and the predicted glycemic index (PGI).</p>

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.

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.

Stinging nettle (Urtica dioica L.) is a good source of biologically active compounds with proven beneficial health effects. This study aimed to investigate the effect of nettle herb supplementation on chemical composition, including the content of selected minerals and pigments, the in vitro glycemic response, and the cooking and sensory quality of extruded pasta. Tagliatelle-shaped pasta was produced under semi-technical scale by partial replacement of durum wheat semolina with 0, 1, 2, 3, 4, and 5% of lyophilized nettle. The partial substitution with freeze-dried nettle caused a statistically significant (p ≤ 0.05) increase in the content of minerals, especially calcium, iron, potassium, and magnesium in the products. The calcium content in the pasta fortified with 5%-addition of stinging nettle was 175.9 mg 100 g−1 and this concentration was 5.8 times higher than in the control sample. At the same time, high content of chlorophylls and carotenoids (237.58 µg g−1 and 13.35 µg g−1, respectively) was noticed. Enriching pasta with a 0–5% addition of stinging nettle resulted in a statistically significant (p ≤ 0.05) increase in the content of the total dietary fiber (TDF) (from 5.1 g 100 g−1 to 8.82 g 100 g−1) and the insoluble dietary fiber (IDF) (from 2.29 g 100 g−1 to 5.63 g 100 g−1). The lowest hydrolysis index of starch (HI = 17.49%) and the lowest glycemic index (GI = 49.31%) were noted for the pasta enriched with 3% nettle.

Abstract Companion animal dietsmay contain up to 50% starch, derived from cereal grains. The amount of resistant starch (RS) in an ingredient depends on the origin and form of the ingredient and on the processing conditions to which the ingredient has been exposed. Extrusion has proven to be a means of optimizing utilization of starch by companion animals. Although the RS fraction of starch typically decreases by extrusion, retrogradation can result in increased concentrations of this fraction. Limited research exists regarding the effects of RS in companion animal nutrition and gastrointestinal health. Existing in vitro and in vivo research indicates that certain RS sources are readily fermented in the large bowel, producing short-chain fatty acids, whereas others are less fermentable, resulting in excellent laxation properties. Feeding dogs a diet high in RS may result in an increase in fecal bulk due to an increased excretion of microbial matter in those cases where RS is highly fermentable, or to indigestibility of the RS source in other cases. RS has a role to play as a potential proxy for dietary fiber, especially for those companion animals fed diets high in protein and fat and devoid of traditional dietary fiber.

Nutritional Benefits

The increasing number of persons following a gluten-free (GF) diet and the need for healthy and natural products are forcing researchers and industries to provide gluten-free products with high nutritional value. Here, a biotechnological approach combining the use of teff flour and type-I sourdough has been proposed to produce GF muffins with nutritional benefits. Teff-sourdough was prepared and propagated following the traditional daily refreshment procedure until the biochemical stability was achieved. The sourdough, dominated by Lactiplantibacillus plantarum, Limosilactobacillus fermentum and Saccharomyces cerevisiae strains, was used to produce muffins at three different levels (up to 15%, wt/wt) of fortification, achieving several positive effects on the nutritional properties of the products. The use of teff flour led to high content of fiber (>3 g/100 g) and proteins (>6 g/100 g) in muffins achieving the nutritional requirements for the healthy claims “source of fiber” and “rich in protein”. Thanks to their metabolic traits, sourdough lactic acid bacteria caused the increase of the total free amino acids (TFAA, up to 1000 mg/kg, final concentration) and phytic acid decrease (50% lower than control), which positively affect the nutritional properties of the products. Besides, high in vitro protein digestibility (IVPD, 79%) and low starch hydrolysis rate (HI, 52%) characterized the fortified muffins. Muffins also presented high in vitro antioxidant (56%) and mold-inhibitory activities, potentially contributing to an extended shelf-life of the products.
