CARACTERÍSTICAS MOLINERAS DE LA LÍNEA MEJORADA DE ARROZ L-37 (ORYZA SP.) CULTIVADA EN LA ZONA DE YAGUACHI, PROVINCIA DEL GUAYAS.

Abstract

Rice (Oryza sativa L.) is a cereal of economic importance in Ecuador and is more accepted when it has good grain quality that manages to express itself in the milling process. The main objective of this research was to determine the milling quality of the promising line of L-37 rice grown in the Yaguachi area, Guayas province.

Two rice cultivars were used: L-37 and SFL-11, analyzed in three replications. This process was carried out in the Grains Laboratory of FACIAG-UTB, which has equipment that was used to determine the variables of: Weight (g) of husks, percentage (%) of moisture, weight (g) of brown rice, weight (g) of white mass, weight (g) of dust, weight (g) of broken grains - rice, weight of whole grains, whiteness, percentage (%) of amylose and protein content. The statistical analysis used was the non-parametric design of Kruskal Wallis including his method of comparing means.

Regarding the results, in relation to the classified rice or whole grains expressed in grams, it was shown that the sample of the commercial variety SFL-11 registers a higher weight, presenting 661.40 g that transformed into percentage would be 66.14 % of whole grains. Based on the amylose content, it is observed that in the commercial variety SFL-11 it had a value of 21.91%, while the promising line L-37 obtained a value of 21.77%, concluding that the amylose contents are similar between the cultivars.
