Comparative effects of slowly digestible and resistant starch from rice in high-fat diet-induced obese mice

The effects of optimized slowly digestible starch (SDS) and resistant starch (RS) from rice starch on weight gain and lipid metabolism in mice (C57BL/6J mice) fed a high-fat diet were investigated. The optimum conditions for SDS were obtained at the pullulanse concentration ( X 1 ) of 498 μL, storage temperature) ( X 2 ) of 47°C, and A/C cycle ( X 3 ) of 5, and for RS, were determined to be 838 μL ( X 1 ), 62°C ( X 2 ), and a cycle of 3 ( X 3 ) using response surface methodology (RSM). Mice fed SDS and RS for 6 weeks showed both significantly decreased weight gain and fat pad weight ( p
