Experimental cookies were formulated with a resistant starch-rich powder (RSRP) prepared from autoclave-treated lintnerized banana starch. The products were studied regarding chemical composition, available starch (AS), resistant starch (RS) and rate of starch digestion in vitro. In order to evaluate the acceptance of RSRP-products, a first affective test was carried out on four cookie formulations containing different RSRP levels. The formulation chosen corresponded to a wheat flour:RRSP ratio of 15:85. Chemical composition of the cookies showed no difference in ash and lipid contents between control (100% wheat flour) and RSRP-cookies (P
