- Free fatty acids in rice bran during its storage after a treatment by twin-screw extrusion to prevent possible rapid hydrolytic rancidity of lipids Beatriz Guevara-Guerrero Alejandro Fernández-Quintero Juan Carlos Montero-Montero Ingeniería storage Rice bran extrusion packaging free fatty acids This research studied the prevention of hydrolytic rancidity during the storage of rice bran stabilized by an extrusion process. A double screw extruder was used, set at 130° C in the barrel and a rotational speed of the screws programmed at 200 RPM. The moisture content of the bran was adjusted at 20%. The treated bran was stored, using two packing methods (with and without vacuum), at two ambient conditions (18° C - 70 % RH and 30° C - 78% RH) for a period of 8 weeks. The content of free fatty acids (FFA) in the rice bran was observed during the storage time period. The extruded treated rice bran stored at 18° C - 70% RH resulted in lower values of FFA in comparison with the values in the bran kept at 30° C - 78% RH. Vacuum packaging showed a significant disadvantage as compared to packaging without vacuum. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49660955021 https://www.redalyc.org/journal/496/49660955021/ https://www.redalyc.org/journal/496/49660955021/html/ https://www.redalyc.org/journal/496/49660955021/49660955021.epub https://www.redalyc.org/journal/496/49660955021/movil 10.15446/dyna.v86n208.72190 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.208 Vol.86
