The aim of the present study was to determine the physico-chemical characteristics of pajuro seeds (Erythrina edulis Triana) and the effects of temperature and moisture on the functional properties of extruded seeds. The mature seeds were conditioned for their physical-chemical characterization and extrusion under three temperature conditions (110, 120 and 130 °C) and two moisture levels (13 and 18%). The results of the physico-chemical characteristics were presented in terms of averages and standard deviations, while the data of the functional properties were submitted to ANOVA under a Completely Randomized Design with 3x2 factorial arrangement and for the comparison of means the Tukey's (p˂0.05) test was used. The seeds presented values of color in the hull like L* (27.26), a* (8.60) and b* (4.81), dimensions of length (4.35 cm), width (2.58 cm) and thickness (1.28 cm); likewise, a v...

The protein digestibility of pajuro seeds (Erythrina edulis Triana) was determined after the conventional cooking process. The processed seeds were dried, ground and incorporated into isoproteic and isocaloric diets for evaluation with Holtzman rats. The results were expressed in terms of means and standard deviations. A one-way analysis of variance (ANOVA) was performed with Tukey's multiple comparison test to determine significant differences (p <0.05) in the proximal composition values ​​and a correlation analysis between protein consumption / gains weight and feed intake / weight gain. A protein value of 20.58 was obtained in the cooked straw seeds, and values ​​of 25.89, 2.97 and 45.56 for feed consumption, weight gain and specific growth rate respectively. Regarding the protein quality indicators, a positive nitrogen balance was obtained with a value of 0.19, biological ...

The main objective of the research was to obtain metohuayo oil by hydraulic pressing versus screw pressing (at 50, 70 and 90 °C). The variables evaluated on the extracted oil were: extraction yield and physical-chemical. The seed stood out for its high fat content (40.5 %) and color L* (29.3), a* (9.7) and b* (18.4). Screw pressing at 50 °C presented the maximum yield and oil recovery values: 39.2% and 96.9%, respectively. The same trend was observed for the quality parameters analyzed: acidity index, peroxide index, p-anisidine index and coefficients K232 and K268, where their values showed an increase related with temperature levels of the screw pressing. The results showed that the set of physical-chemical characteristics allow the recognition and differentiation of the oils obtained in relation to temperature levels, and through a Principal Component Analysis (PCA) it was possible ...
