The application of collagen preparations as carriers of rosemary extract in the production of wiener-type and liver sausages has been evaluated. The rosemary extract was introduced into the meat products using one of two carriers (collagen hydrolyzate or collagen fibre preparation) or directly (i.e. using no carriers). The relationship between the methods of extract introduction and its antioxidative action was assessed on the basis of the lipid oxidation (i.e. determination of peroxide value and TBARS) during cold storage of sausages in air or in vacuum. The introduction of rosemary extract to the products via the collagen fibre preparation limited lipid oxidation greater than the direct addition of the antioxidant to both meat products, irrespective of storage. On the contrary, in the case of the application of collagen hydrolyzate as a carrier of extract, a masking effect was observed, diminishing the antioxidative impact on the tested products.
