Lipid digestion and oxidative stability in ω-3-enriched meat model systems: Effect of fish oil microcapsules and processing or culinary cooking.

This study evaluates the addition of monolayered (MO) and multilayered (MU) fish oil microcapsules to meat model systems and determines the effects of processing and culinary cooking. Adding MO and MU increased the content of EPA and DHA and the level of secondary oxidation products but being far away from the oxidation values that generate anomalous flavours. However, it did not lead to oxidative damage of the enriched batches or affect the moisture and lipid content during processing and/or culinary cooking. The type of fish oil microcapsules, the processing and/or culinary cooking and the type of meat matrix influenced the fatty acid digestion. The highest bioaccessibility of EPA and DHA occurred in cooked samples enriched with MO after processing and before culinary cooking. To optimize EPA and DHA enrichment and bioaccessibility, the type of fish oil microcapsules may be selected as a function of the type of added meat products.
