- Syrup production via enzymatic conversion of a byproduct (broken rice) from rice industry Wilma Aparecida Spinosa Vitório dos Santos Júnior Diego Galvan Jhonatan Luiz Fiorio Raul Jorge Hernan Castro Gomez Ingeniería liquefaction Gelatinization enzymatic hydrol ysis response surface methodology (RSM) In a hydrothermal process for the gelatinization of the rice starch, it was studied the rate of hydration, temperature and time. An incomplete 3 3 factorial design was used to evaluate the effects of temperature, enzyme/substrate relation and liquefac tion time, with dextrose equivalent (DE) as the response variable. The maximum value obtained was 14. 69% DE at 89ºC, with 0.21% (w/w) of enzyme to substrate in 22 minutes. For saccharification, it was st udied enzyme/substrate ratios (0.6, 2.4, 4.2 and 6.0% (w/w)) at 60ºC at a pH of 4.30, yielding 49.23, 69. 65, 65.12 and 74.67% DE, respectively, after 72 hours. The syrup had a content of 12.78, 16.87, 15.96 and 17.87% of glucose (w/v), pH 2.60 - 2.71. The starch content converted into glucose after liquefaction was 61.80% and after saccharification ranged from 75.16 to 77.05% for the relation enzymes substrate tested. 2016 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303243563003 https://www.redalyc.org/journal/3032/303243563003/ https://www.redalyc.org/journal/3032/303243563003/html/ https://www.redalyc.org/journal/3032/303243563003/303243563003.epub https://www.redalyc.org/journal/3032/303243563003/movil en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
