Formation of Resistant Starch by a Twin-Screw Extruder

摘要: ABSTRACT The objective of this study was to evaluate the potential increase level resistant starch (RS) in extruded products by optimizing extruder conditions. Three experiments were conducted as randomized complete block designs with two replicates. In first experiment, corn starch, wheat and potato added at a 30% (w/w) degerminated yellow meal investigate influence type. second citric acid (CA) monohydrate levels 0, 2.5, 5, 7.5% (w/w). third experiment full-factorial arrangement effect high-amylose (HACS) (0, 15, 30%, w/w) CA 7.5%, screw speeds (200 300 rpm). means for RS plus dietary fiber different formulations ranged from 1.27 2.28%. 2, adding increased content maximum 5.23% CA. ...
