Response surface analysis and process optimization of non-cereal (elephant foot yam, taro and water chestnut) snacks
The present study was conducted to develop non-cereal starch extruded products. The effects of feed moisture (15-21%), temperature (130-170 °C) and screw speed (120-160 rpm) were evaluated on the physical and functional properties of extruded snacks using response surface methodology. Feed moisture and screw speed increased the bulk density and hardness of extruded snacks. Significant decreases in water absorption index and increases in water solubility index were observed with increases in extrusion temperature. The best conditions were determined by numerical optimization. The optimized value for non-cereal snacks for feed moisture is 18.22%, temperature 155.96 °C, screw speed 142.75 rpm and, desirability is 0.75. Verification of results showed decent agreement between the responses of experimental values at certain optimum conditions and the predicted values.
期刊介绍：
he International Journal of Food Studies (IJFS), a journal of the ISEKI_Food Association, is an international peer-reviewed open-access journal featuring scientific articles on the world of Food in Education, Research and Industry. This journal is a forum created specifically to improve the international dissemination of Food Science and Technology knowledge between Education, Research and Industry stakeholders. Original contributions relevant to the following topics will be considered for publication: -Education methods, including Life Long Learning and e-learning; -Research and application in academia, research, industry; -Critical reviews of scientific literature by researchers, students, invited authors; -Exchange of views and opinions of a scientific nature including testimonies on career experiences in Food Industry/Research/Education (required skills, challenges and successes). Manuscripts focusing on Food related Education topics are particularly welcome.
