lood glucose levels do not raise as rapidly after fructose consumption compared to other simple sugars and complex carbohydrates. Butter cake is a low dietary fiber, complex fat and water emulsion system containing flour, milk, sugar, fat, eggs and baking powder (Bennion, 1995b). A proper combination of the ingredients can give a high-quality product with desirable flavor and texture. From a physiological standpoint, as low glycemic ingredients, has none of the published report describe the practical use of RS III and high fructose corn syrup in butter cake. The effects of RS III and high fructose corn syrup application in butter cake on physicochemical properties and sensory evaluations of the developed butter cake were investigated. The stability of RS III to tolerate varying processing conditions in the cake on starch digestibility, hydrolysis index and glycemic index were examined using in vitro analysis. 3
Overall objectives: OBJECTIVES 1. To produce resistant starch type III (RS III) from high-amylose rice starch by enzymatically-debranching process. 2. To produce low glycemic butter cake product by using RS III from high amylose rice starch and high fructose corn syrup. Specific objectives: 1. To study the physiochemical properties of native high-amylose rice starch 2. To investigate the effect of preheated treatments of rice starch on degree of hydrolysis, degree of syneresis of debranched products and in vitro starch digestibility of RS III formation. 3. To investigate the effect of pullulanase enzyme concentrations on degree of hydrolysis, degree of syneresis, β-amylolysis of debranching products and in vitro starch digestibility of RS III formation. 4. To examine granule structure and crystallinity of RS III with a scanning electron microscopy (SEM) and X-ray diffraction pattern. 5. To investigate the optimum level of RS III and high-fructose corn syrup in butter cake by sensory evaluation and physicochemical analysis. 6. To examine an in vitro starch digestibility, hydrolysis index and estimated glycemic index of butter cake with RS III and high-fructose corn syrup replacement of wheat flour and sucrose. 4
