RAMIREZ-PEREZ, Ana Rosa et al. Method to evaluate amaranth grain trapping. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.3, pp.675-682. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i3.1224.

To define a procedure to evaluate amaranth grain expansion, three experiments were established. The first, to optimize the method of determination of humidity in grain in drying oven. The second to define the feasibility of modifying the moisture content to 12, 14 and 16%, due to the effect of water quantity and conditioning time. The third was to determine the volume of grain expansion by sample size (15 and 30 g) and humidity (10, 12, 14 and 16%). The treatment that worked best for the determination of grain moisture was 2 g of sample, 2 h of drying at 130 °C. It is possible to modify and adjust the grain moisture content by adding water. No effect on the moisture content was observed for the different conditioning times. The moisture content with which the highest trapping volume was obtained was 12 and 14%. There were no significant differences in the volume of grain trapping in samples of 15 and 30 g.

Keywords : conditioning; grain moisture; expansion volume.
