Apple pomace powder was analyzed for its functional properties which showed water holding capacity and fat absorption capacity of g/g and ml/g, respectively. Foam of apple pomace powder was not stable. Hypoglycemic potential of dietary fibers in managing diabetes is very well documented. In present study, the effect of apple pomace powder on α–amylase, glucose diffusion and glucose adsorption were studied by using in vitro studies. The mechanism by which dietary fiber of apple pomace powder could exerts hypoglycemic effect includes inhibiting amylase activity, glucose adsorption capacity and glucose diffusion retardation index. α- amylase inhibition ration in apple pomace powder was observed 80 per cent. Glucose diffusion retardation index (GDRI) was maximum at 30 min () while found decreased after 30 minutes. Glucose adsorption capacity (GAC) of apple pomace powder increased gradually with increase of glucose concentration. All of these mechanisms contribute towards the rate of reduction of glucose adsorption in the intestine, as a result, decrease the postprandial serum glucose concentration. | 2019 8 3 589-595 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 03 2019 Journal homepage http Original Research Article https Functional Properties of Apple Pomace Powder Taru Negi and Devina Vaidya Department of Food Science and Technology Dr. YS Parmar University of Horticulture and Forestry Nauni Solan HP Corresponding author ABSTRACT Keywords Apple pomace powder Hypoglycemic a -amylase GDRI GAC Article Info Accepted 07 February 2019 Available Online 10 March 2019 Apple pomace powder was analyzed for its functional properties which showed water holding capacity and fat absorption capacity of g g and ml g respectively.

Introduction Apple pomace main by-product of apple juice industry contains per cent wb moisture and per cent carbohydrates Sun et al. 2007 . It can be considered as a raw material for extraction of dietary fiber since it contains .
