Sažetak
Introduction: Apple pomace, as a main by-product in production of apple juice, cider and related products, is a nutritionally valuable raw material, rich in pectins, dietary fibres, polyphenols, etc. Because of that, apple pomace can be incorporated in various types of products, usually in production of cookies and bread. Objective: The aim of this research was to investigate the potential of apple pomace application in production of corn snack products. Materials and methods: Dried apple pomace was added in corn grits in proportions of 5, 10 and 15%. Prepared mixtures with 15% of moisture content were extruded in the laboratory single screw extruder. Obtained extrudates were air-dried overnight and milled in laboratory mill prior the analysis. Total, soluble and insoluble dietary fibres, resistant starch, starch damage, antioxidant activity, total polyphenols, acrylamide and hydroxymethylfurfural content were determined. Results: Addition of apple pomace significantly increased dietary fibres and polyphenol content, as well as antioxidant activity. After extrusion process starch damage and antioxidant activity significantly increased, while resistant starch content and total polyphenol content decreased. Furthermore, extrudates with higher portions of apple pomace had higher content of acrylamide and hydroxymethylfurfural, but these concentrations were low and it can be concluded that these products are safely for consumers. Conclusion: Results obtained in this investigation show that apple pomace can be successful incorporated in corn grits with the aim of production nutritionally more valuable corn snack products.
