Nugget is a ground meat product which is seasoned, then covered with flour adhesive, breaded and half-fried and then frozen to maintain its quality during storage. The addition of carbohydrates or fillers to nuggets can reduce costs derived from the main ingredient, namely meat. This study aims to analyze the starch content, amylopectin, amylose, and water content of Provit A1 corn flour used in the processing of rejected duck nuggets. The research design used was a completely randomized design (CRD). The treatment in this study was Provit A1 corn with 10%, 20%, 30% and 40% content, with 4 replications. The measurement variables were: starch content, amylose content, amylopectin content, air content. The results showed that the use of provit A1 corn flour had a significant effect (P<0.05) on starch content, amylose content, amylopectin content, water content. The conclusion of the results of this study is the use of provit A1 30% corn flour can give good results as a filler for starch content, amylose content in rejected duck nuggets.
