Galletas tipo soda elaboradas con sustitución parcial de harina de trigo por harina de maíz nixtamalizado y garbanzo / Soda-type crackers with partial replacement of wheat flour with nixtamalized corn and chickpea flour

Introducción: En el Perú, el 90% de trigo es importado y su alta cotización internacional (390 dólares TN-1) implica la necesidad de encontrar sustitutos principalmente en productos de panificación que en su mayoría son formulados a base de trigo. Las harinas provenientes de frijol garbanzo y maíz amarillo, pueden mostrarse como alternativas potenciales y contribuir a mejorar el valor nutricional y sensorial del alimento. Objetivo: Desarrollar y evaluar nutricionalmente y sensorialmente una galleta tipo soda sustituyendo parcialmente la harina de trigo (HT) por harina de maíz amarillo (Zea mays) nixtamalizado (HMN) y garbanzo (Cicer arietinum) (HG). Materiales y métodos: Se realizaron tres formulaciones, F1: 70% HT, 20% HMN y 10% HG, F2: 70% HT, 10% HMN y 20% HG y F3: 50% HT, 20% HMN y 30% HG, la muestra control contenía 100% harina de trigo. Se determinaron contenido de proteínas, grasa y carbohidratos por análisis proximal, así como sabor y textura en el análisis sensorial. Resultados: F3 presentó mayor contenido de proteínas (11,88%), grasa (3,70%), y carbohidratos (71,08%), mientras que F2 fue percibido por los panelistas con un sabor moderadamente salado y de textura crujiente. Conclusiones: Se concluye que una sustitución mayor al 50% de harina de trigo por harina de leguminosa y harina de maíz nixtamalizada permite obtener galletas con alto contenido proteico y de textura similar a una galleta tipo soda comercial(AU)

Introduction: In Peru, 90% of wheat is imported and its high international price ($390 per TN) implies the need to find substitutes mainly in baking products that are mostly formulated with wheat. Flours from chickpeas and yellow corn can be shown as potential alternatives and contribute to improving the nutritional and sensory value of the food. Objective: Develop and nutritionally and sensorially evaluate a soda cracker partially substituting wheat flour (HT) with nixtamalized yellow corn flour (Zea mays) (HMN) and chickpea (Cicer arietinum) (HG). Material and methods: Three formulations were made, F1: 70% HT, 20% HMN and 10% HG, F2: 70% HT, 10% HMN and 20% HG and F3: 50% HT, 20% HMN and 30% HG, the control samplecontained 100% wheat flour. Protein, fat and carbohydrate content were determined by proximal analysis, as well as flavor and texture were determined in sensory analysis. Results: F3 presented a higher content of proteins (11.88%), fat (3.70%), and carbohydrates (71.08%), while F2 was perceived by the panelists as having a moderately salty flavor and crunchy texture. Conclusions: It is concluded that a substitution of more than 50% of wheat flour by leguminous flour allows obtaining crackers with high protein content and a texture similar to a commercial soda cracker(AU)

Effects of graded inclusion levels of raw garbanzo beans on apparent total tract digestibility, fecal quality, and fecal fermentative end-products and microbiota in extruded feline diets.

Garbanzo beans (GB; Cicer arietinum) are a readily available pulse crop that have gained popularity as a plant-based protein source in the pet food industry. However, raw GB contain anti-nutritional factors that can reduce digestibility and cause digestive upsets in pets that are undesirable to owners. The objective of this study was to determine the effects of the inclusion of raw or cooked GB in extruded feline diets on macronutrient digestibility, gastrointestinal tolerance, and fermentative end-products in cats. Five diets were formulated to contain raw GB at 0%, 7.5%, 15%, or 30% or cooked GB at 30%. Ten adult, male cats (mean age: 1.0 ± 0.0 yr, mean BW: 4.7 ± 0.4 kg) were used in a replicated 5 × 5 Latin square design. Each period consisted of 14 d, with 10 d of diet adaptation followed by 4 d of total fecal and urine collection. At the end of each period, 4 mL of blood were collected and analyzed for a serum chemistry and complete blood count to ensure all animals remained healthy throughout the study. Cats were fed twice daily and food intake was calculated to maintain body weight. Food intake was highest (P < 0.05) for cats fed 0% raw GB (72.2 g/d, dry matter basis [DMB]) compared with GB inclusions of 7.5% or greater (average 70.3 g/d, DMB). Dry matter and organic matter apparent total tract digestibility (ATTD) were lowest (P < 0.05) for cats consuming the 30% cooked GB diet (77.3% and 81.7%, respectively). Cats fed 7.5% raw GB had greater (P < 0.05) crude protein ATTD (86.2%) than cats fed 15% raw GB (82.3%) or 30% cooked GB (81.6%). Total short-chain fatty acid concentrations were highest (P < 0.05) for 30% cooked GB at 682 µmol/g but not different (P > 0.05) than 15% GB (528 µmol/g) or 30% raw GB (591 µmol/g) diets. In terms of fecal microbial abundance, the predominant phyla were Firmicutes, Bacteroidota, and Actinobacteria. Cats fed the 0% GB diet had a greater relative abundance of Firmicutes (62.1%) and Fusobacteria (4.0%) than the remaining diets (average 54% and 1.6%, respectively). In conclusion, all inclusion levels of raw GB resulted in high digestibility (average > 80%) and ideal fecal scores (average 2.9), demonstrating their adequacy as a protein source in feline diets up to a 30% inclusion level.

Incorporating sprouted chickpea flour in pasta increases brachial artery flow-mediated dilation.

PURPOSE: Consumption of alternative flours, such as sprouted chickpea flour, has shown increased popularity in recent years. Foods rich in antioxidants have been shown to influence brachial artery flow-mediated dilation (FMD), a non-invasive test of a crucial layer of the artery called the endothelium. Partially replacing the semolina flour in pasta with sprouted chickpea flour (SCF) may acutely affect endothelial function post-digestion. We sought to determine if FMD was higher, lower, or the same post-digestion of pasta made with 60% semolina flour and 40% SCF (SCF40) vs. post-digestion of pasta made with 100% semolina flour (SEM100, i.e., control). METHODS: Trolox equivalent antioxidant capacity (TEAC) analysis was performed on the same flour samples. Healthy participants underwent a screening visit and two randomized controlled meal data collection visits (SCF40 and SEM100). At each data collection visit, participants consumed 255 g of pasta with butter. FMD was assessed 2-3 h after pasta consumption. RESULTS: TEAC results showed that SCF40 (2.031 ± 0.096 mmol trolox/100 g sample) had significantly greater antioxidant capacity than SEM100 (1.736 ± 0.046 mmol trolox/100 g sample; p = 0.02). Twenty-two healthy participants (5 men and 17 women; 26 ± 2 years, 66.6 ± 2.3 kg, BMI = 24 ± 1 kg/m2, SBP = 114 ± 3 mmHg, DBP = 75 ± 2 mmHg, HR = 74 ± 3 BPM) were studied. FMD in the SCF40 condition (10.3% ± 1.2%) was greater than the SEM100 condition (7.9% ± 0.8%, p = 0.02). CONCLUSION: These data suggest that partial substitution with sprouted chickpea flour in place of semolina flour in pasta acutely improves post-digestion FMD, which may be beneficial for cardiovascular health (ClinicalTrials.gov Identifier: NCT03801486).

Enzymatic Production, Bioactivity, and Bitterness of Chickpea (Cicer arietinum) Peptides.

Chickpeas are inexpensive, protein rich (approximately 20% dry mass) pulses available worldwide whose consumption has been correlated with positive health outcomes. Dietary peptides are important molecules derived from dietary proteins, but a comprehensive analysis of the peptides that can be produced from chickpea proteins is missing in the literature. This review provides information from the past 20 years on the enzymatic production of peptides from chickpea proteins, the reported bioactivities of chickpea protein hydrolysates and peptides, and the potential bitterness of chickpea peptides in food products. Chickpea peptides have been enzymatically produced with pepsin, trypsin, chymotrypsin, alcalase, flavorzyme, and papain either alone or in combination, but the sequences of many of the peptides in chickpea protein hydrolysates remain unknown. In addition, a theoretical hydrolysis of chickpea legumin by stem bromelain and ficin was performed by the authors to highlight the potential use of these enzymes to produce bioactive chickpea peptides. Antioxidant activity, hypocholesterolemic, and angiotensin 1-converting enzyme inhibition are the most studied bioactivities of chickpea protein hydrolysates and peptides, but anticarcinogenic, antimicrobial, and anti-inflammatory effects have also been reported for chickpea protein hydrolysates and peptides. Chickpea bioactive peptides are not currently commercialized, but their bitterness could be a major impediment to their incorporation in food products. Use of flavorzyme in the production of chickpea protein hydrolysates has been proposed to decrease their bitterness. Future research should focus on the optimization of chickpea bioactive peptide enzymatic production, studying the bioactivity of chickpea peptides in humans, and systematically analyzing chickpea peptide bitterness.

Influence of processing conditions on apparent viscosity and system parameters during extrusion of distiller's dried grains-based snacks.

A combination of different levels of distillers dried grains processed for food application (FDDG), garbanzo flour and corn grits were chosen as a source of high-protein and high-fiber extruded snacks. A four-factor central composite rotatable design was adopted to study the effect of FDDG level, moisture content of blends, extrusion temperature, and screw speed on the apparent viscosity, mass flow rate or MFR, torque, and specific mechanical energy or SME during the extrusion process. With increase in the extrusion temperature from 100 to 140°C, apparent viscosity, specific mechanical energy, and torque value decreased. Increase in FDDG level resulted in increase in apparent viscosity, SME and torque. FDDG had no significant effect (p > .5) on mass flow rate. SME also increased with increase in the screw speed which could be due to the higher shear rates at higher screw speeds. Screw speed and moisture content had significant negative effect (p < .05) on the torque. The apparent viscosity of dough inside the extruder and the system parameters were affected by the processing conditions. This study will be useful for control of extrusion process of blends containing these ingredients for the development of high-protein high-fiber extruded snacks.

Efecto de la variedad y la fertilización en indicadores de calidad proteica in-vitro de dos variedades y una línea de garbanzo (cicer arietinum) / Variety and fertilization effect on indicators of protein quality in-vitro of two varieties and one line of chickpea (cicer arietinum)

Protein quality in relation to the degree of fertilization of two varieties (Costa and Blanco Sinaloa) and an advanced line (Hoga L10) of chickpeas obtained from the Campo Experimental Costa de Hermosillo, Sonora, Mexico from INFAP was evaluated. They were grown in similar conditions with 3 levels of nitrogen fertilization (60,120 and 200K/Ha.). Protein and non-protein nitrogen, digestibility and available lysine were analyzed. Significant differences between the varieties and the advanced line in protein and non-protein nitrogen and available lysine were found. The effect of the degree of fertilization on protein quality was significant, showing that a level ofl20KI Ha an increase is observed in protein and non-protein nitrogen and in the percent of digestibility. No significant differences were observed between 60 and 200KIHa. Available lysine was higher at the 200KIHa level. These indicators of protein quality can be used to complement commercial and agricultural aspects that are evaluated for improvement and selection of new varieties of chickpeas.

En este trabajo se evaluó la calidad proteica in-vitro en dos variedades y una línea avanzada de garbanzo, así como su relación con el grado de fertilización aplicado durante su cultivo. Se utilizaron dos variedades comerciales de garbanzo (Costa y Blanco Sinaloa) y una línea avanzada Hoga L10, sembradas en condiciones ambientales similares, con tres niveles de fertilización de nitrógeno (60, 120 y 200K/Ha.), las cuales fueron obtenidas del Campo Experimental Costa de Hermosillo, Sonora, México del INIFAP. Se llevó a cabo un análisis químico proximal, determinaciones de calidad proteica como: nitrógeno proteico y no proteico utilizando extracciones con ácido tricloroacético, digestibilidad in-vitro por el método multienzimático y lisina disponible. A excepción de digestibilidad in-vitro se observaron diferencias significativas entre las variedades y línea avanzada en: nitrógeno proteico, no proteico y lisina disponible. El efecto de la fertilización fue observado en todos las determinaciones de calidad proteica, los resultados indicaron que al aumentar el nivel de fertilización a 120K/Ha se obtiene un incremento significativo en el porcentaje de nitrógeno proteico y no proteico, así como el porcentaje de digestibilidad. Entre los niveles de 60 y 200K/Ha no se observaron diferencias significativas. La lisina disponible fue mayor en las variedades y líneas con nivel de fertilización de 200K/Ha. Estos indicadores de calidad proteica pueden complementar a los aspectos agronómicos y comerciales que son evaluados en los programas de mejoramiento, en la selección de nuevas variedades de garbanzo para su explotación comercial.

The present study had three objectives: 1) To determine the best combination of quality extruded protein maize flour (EMF) and extruded chickpea flour (ECF) for producing a weaning food of high quality protein and high sensory acceptability, 2) to make a kind of infant food (atole) with an optimal EMF/ECF blend, and 3) to evaluate the nutritional properties of the optimized EMF/ECF mixture and the weaning food. Response surface methodology was applied to determine the optimal EMF/ECF combination. The best EMF/ECF combination was 21.2:78.8%. This mixture contained (in dry matter) 20.07% protein, 5.70% lipids and 71.14% carbohydrates; its essential amino acids (EAA) profile satisfactorily covered the requirements for children 2-5 years old recommended by FAO/WHO, except for tryptophan. The atole-type weaning food prepared with the optimized mixture had a protein content of 4.52%, which accounts for 14.4% of the supplied energy, suitable for a weaning food. Each 100g of the weaning food supply, respectively, 6.3-12.6% and 23.8-34.8% of the daily energy and protein requirements for children 1-8 years old. The weaning food had a 62.1% protein digestibility in vitro, a C-PER of 1.93, and was evaluated between "very liked" and "extremely liked" in a hedonic test for overall acceptability. This food could be used to support the growth of infants.
