Item Effects of spray drying and lactic acid fermentation on the technological characteristics of yellow and green pea (Pisum sativum L.) Protein products(Agricultural and Food Science, 2024) Guraya, María Ángeles; Iguti, Antonia Miwa; De Ros Triboli, Edison Paulo; Ribeiro, Eliana Paula; Accoroni, Cecilia; Espósito, María Andrea; Torresi, Pablo Antonio; Reinheimer, María Agustina; Godoy, EzequielThis research evaluates a pH-shifting and drying process for producing powdered protein products from yellow and green peas (Pisum sativum L.), aiming to enhance their technological characteristics. In the precipitation stage, lactic acid bacteria (Lactobacillus Plantarum and Lactobacillus Lactis) served as a generally recognized safe precipitant agent. The fine fraction (<150 µm) from yellow and green peas milling acted as an encapsulant/adjuvant agent in the drying stage. Results showed high process productivity (0.41–0.51 kg protein product/kg pea flour) and low specific water consumption (52.58–62.39 kg water/kg protein product) with this approach. Variations in processing parameters affected protein content, yield, and specific water consumption. Significant differences were observed in wetting time, water activity, flowability (Carr index), cohesiveness (Hausner index), density, particle size, and colour of the protein products, depending on the processing alternatives. This flexibility allows tailoring the properties of the powdered protein product for various food technology applications.Item Evaluación de la composición y producción de concentrados proteicos de diferentes variedades de arveja amarillas y verdes (Pisum sativum L.)(INTA, 2024) Accoroni, Cecilia; Espósito, María Andrea; Magnano, Luciana; Guraya, María Ángeles; Godoy, Ezequiel; Reinheimer, María A.El aumento constante en los últimos años de la población mundial provocó la búsqueda de fuentes proteicas vegetales alternativos a las proteínas animales. La arveja es una excelente alternativa, en su formato de concentrados y aislados proteicos, como ingredientes en la industria alimentaria, garantizando una alimentación suficiente y sostenible para vegetarianos, veganos y celíacos. El objetivo de este trabajo fue evaluar la potencialidad comercial de una variedad comercial y dos variedades precomerciales del programa de mejoramiento INTA-FCA UNR (Primogenita, B320 y B313, respectivamente) en comparación con seis variedades comerciales, (Reussite, Viper, Kingfisher, Aragorn, Meadow y Astronaute) contemplando la composición de las harinas crudas y la solubilidad de las proteínas. Se encontró que el contenido proteico fue superior en los tres años de evaluación para Primogénita, Viper (ambas de semilla verde) y B320, Reussite y Meadow (de semillas amarillas). Además, que tanto el contenido proteico como solubilidad resultaron ser superiores en las harinas crudas provenientes de variedades verdes, lo cual facilita la disponibilidad de proteínas totales a ser extraídas durante la producción de aislados/concentrados proteicos. Respecto a la solubilidad, se observan valores superiores a 65 % indicando disponibilidad de proteínas extraíbles por no sufrir desnaturalización durante su acopio y molienda. Se detectaron valores de actividad ureásica inferiores a 0,300. Esto indica que no es necesario aplicar tratamiento térmico además de una posible disminución de la proteína soluble. Para rendimiento de proteína, Primogénita tuvo los mayores rendimientos (>50%) en los tres años. Esta variedad resulta ser promisoria para la producción de concentrados/aislados proteicos ya que tiene un mayor contenido de proteína y disponibilidad para ser extraídas con un alto rendimiento de producto. Estos resultados abonan al programa en pro de obtener variedades con buen comportamiento agronómico y producción de concentrados proteicos potenciando el agregado de valor en la industria alimenticia.Item Enhancing protein extraction from soybean expeller: exploring the impact of precipitating agents and flour-to-water ratios on functional properties(2024-07) Andrín, María Nieves; Guraya, María Ángeles; Accoroni, Cecilia; Torresi, Pablo Antonio; Godoy, Ezequiel; Reinheimer, María AgustinaThis study investigates sustainable methods for producing protein from soybean expeller via pH-shifting processes, aiming to reduce water usage in alkaline extraction by adjusting solid23 to-liquid ratios per cycle and employing isoelectric precipitants like lactic acid and lactic acid bacteria (Lactiplantibacillus plantarum and Lactococcus Lactis) to enhance functional and antioxidant properties over a wide pH range. Results indicate that the most efficient approach involves three 1:10 (w/v) extraction cycles with lactic acid bacteria as precipitants, demonstrating high productivity and low specific water consumption. Protein content and recovery yield showed no significant differences compared to alternatives with higher water consumption or less eco-friendly precipitants. Despite lower solubility, protein products precipitated with lactic acid bacteria formed stable emulsions, exhibiting superior free radical scavenging activity.Item Economic evaluation of protein recovery process from Argentinian soybean extruded-expelled meals.(2022) Accoroni, Cecilia; Godoy, Ezequiel; Reinheimer, María AgustinaSoybean extruded-expelled (EE) meals are the byproduct of the soybean oil extraction process commonly used by small and medium- sized Argentinean companies. In this study, the economic feasibility of protein concentrate production from soybean EE meals was evaluated. A processing daily capacity of 18 ton of EE meals was considered, resulting in an annual production of 1,500 ton of protein concentrate. The proposed methodology considered a pH change process consisting of 3 cycles of alkaline extraction at 60 ºC followed by isoelectric precipitation at low temperature using hydrochloric acid, which resulted in a final product with a protein content of 75 % (db) and a productivity of 0.28 kg product/kg soybean EE meals. To analyze a practical case, proposed production was carried out as an extension of a typical medium-sized soybean extrusion- expelling plant. As a result, the necessary capital investment was estimated to be US$2.7 million. Additional financial performance indicators were computed, including net present value and internal rate of return, and it was concluded that the proposal to obtain a protein concentrate from soybean EE meals was economically viable on an industrial scale if sale prices are above 2,267 US$/ton.Item Análisis de la molienda de expeller de soja evaluando la performance de diferentes tipos de molinos.(2017) D’Emanuele Ares, Carolina; Accoroni, Cecilia; Ferigutti, Leonardo; Godoy, Ezequiel; Reinheimer, María AgustinaEl objetivo del presente trabajo es analizar la performance del proceso de molienda y tamizado de expeller de soja, subproducto de la extracción de aceite por el método de extrusado-prensado, para su posterior utilización en la obtención de productos proteicos. La molienda se realiza con tres molinos diferentes: de bolas (impacto), de rodillos (cizalla y compresión) y de cuchillas (cizalla), bajo diferentes condiciones de operación. El análisis de tamizado se realiza utilizando la serie de tamices ASTM Nº 5, 6, 10, 12, 25, 30 y ciego. Los productos obtenidos se clasifican en finos, medios, y gruesos, analizándose así los rendimientos de cada fracción en cada molino. Al ser la fracción de interés la correspondiente a las partículas de tamaño medio, se concluye que los molinos de cuchillas y de rodillos son mas adecuados debido a que se alcanzan rendimientos superiores al 55% cuando se los opera con una sola pasada. Asimismo, se calculan y reportan las energías especıficas desarrolladas en las moliendas con la Ley de Bond para exponer una comparativa.Item Experimental data acquisition and mathematical model for soluble protein extraction from Argentinian extruded expeller soybean meal(2019-06) Accoroni, Cecilia; Godoy, Ezequiel; Reinheimer, María AgustinaExtruded expeller soybean meal is a byproduct of the soybean oil extraction, which is frequently used in Argentina by animal feed millers. In this work, the soluble protein extraction stage is studied as the first step of a challenge project in order to obtain a soy protein product from this byproduct. Extruded expeller (EE) meals from 4 different Argentinian processing plants were used to obtain experimental data sets, using 1 to 3 consecutive extraction cycles operating at temperatures from 55 to 65ºC. Firstly, 16 data sets were used to estimate the values of the distribution constant and the diffusivity of proteins within the particle, both as function of the extraction temperature. The remaining 25 data sets were used for validation purposes. Extraction yields were analyzed considering the impact of the operating conditions, while a good agreement between experimental and predicted extraction yields was achieved as the reported statistical parameters indicate.Item Novel nutritionally improved snacks for school-aged children: formulation, characterization, and acceptability.(2022-04) Lingiardi, Nadia; Godoy, Ezequiel; Arriola, Ileana; Cabreriso, María Soledad; Accoroni, Cecilia; Balzarini, María Florencia; Arribas, Alberto; Reinheimer, María AgustinaPurpose: This study aimed to formulate multiple nutritionally improved snacks intended for school-aged children according to international nutritional goals: Vanilla cookies (VC), Bay biscuits (BB), Cheese crackers (CC), and Tomato muffins (TM). Design/methodology/approach: The reformulation targets implied incorporating alternative flours and milk powder, and reducing the sugar and sodium contents, with respect to the usually consumed control products. These products were subjected to proximate composition, colour, and sensory profile analyses. Their overall acceptability was assessed by school-aged children whose nutritional status was also evaluated. Findings: Significant increments in relevant nutrients were observed in the composition of snacks: fibre (p=0.01 for VC, p<0.01 for BB and CC), proteins (p<0.01 for all snacks), and calcium (p<0.01 for all snacks). Average sodium reductions of 1.5 % and 3.7 % were achieved for CC and TM. During formulation, added sugar was reduced by 15.5 % and 23.5 % for VC and BB. All snacks were found to be acceptable in terms of appearance, texture, flavour, and overall acceptability by the participants, and VC, BB, and CC were ready for their effective implementation as part of school meals. Originality/value: Comprehensive policies have become necessary to combat malnutrition, mainly overweight and obesity. The incorporation of nutritionally improved snacks in school environments is one of several strategies for promoting healthier lifestyles among children, including educational programs, workshops, and food assistance.Item Performance evaluation of protein recovery from Argentinian soybean extruded-expelled 2 meals under different operating conditions.(2020-06) Accoroni, Cecilia; Godoy, Ezequiel; Reinheimer, María AgustinaThe soybean extruded-expelled (EE) meals are the byproduct of the process commonly used by small or medium-sized Argentinian companies for obtaining soy oil. In this work, the performance of the pH-shifting process for obtaining a protein product from the EE meals was evaluated as a strategy for on-site value-adding. The EE meals were subjected to the proposed pH-shifting process under different operating parameters at the alkaline extraction stage (2 and 3 cycles at 55, 60 and 65 ºC with and without sodium sulfite) and isoelectric precipitation stage (0 ºC and 20 ºC with hydrochloric and phosphoric acids), which constitute the controlling steps in an industrial scaling of the process. The pH-shifting process consisting of 3 alkaline extraction cycles at 60 ºC followed by isoelectric precipitation at low temperature using hydrochloric acid was found to be well suited for obtaining a final product with a protein content upwards of 75 %.
