Physicochemical characteristics in different degrees of maturation of the fruits of three promising lines of piñón and quality of oil extraction from seeds

In this work, the behavior and physicochemical characteristics of fruits, seeds and oil extracted from three promising sprocket lines CP041, CP052 and CP054 with degrees of maturation were evaluated: light green, yellow, yellowish brown and dark brown. The samples were obtained from the germplasm bank of the Portoviejo Experimental Station of the National Institute for Agricultural Research (INIAP-EEP), Manabí, Ecuador. In the statistical analysis, it was determined that the ripe fruits were the ones that presented the highest percentage of oil content, being the line CP041 the one that presented the highest content. In the percentage of seeds in nuts, the CP041 line had a higher yield than the CP054 line. As for proteins, the CP041 line stood out, in percentage of fiber and humidity CP052 and in percentage of ash CP054. In line CP041, the light green fruit oil had a higher iodine index and a saponification index. The kinematic viscosity in the yellow fruit was the most outstanding with the other degrees of ripening. The yellowish-brown fruits presented the lowest acidity index. When the fruits studied were dark browns, there was a lower peroxide index and a lower range relative density. The fruits with the highest content of double bonds referring to the Iodo index were light green fruits in line CP052, while in line CP054 they were dark brown fruits. The dried fruits (dark brown) of the line CP052 and CP054 reached a high saponification index in relation to the other degrees of ripeness. The values shown in the kinematic viscosity in the yellowish-brown fruits stand out from the other ripening stages in both the CP052 and CP054 lines. In relative density, both in lines CP052 and 51 CP054, the yellow-green fruits stand out in relation to the other ripening stages.
