Affecting Factors

The tissues of animals for food use have come to be associated with a predominance of saturated and monounsaturated fatty acids, the result of which has been to contribute to the perceived human dietary imbalance of fatty acids. The fact that porcine tissues assume a fatty acid composition similar to that of the respective diet has enabled the composition to be altered with respect to human dietary needs (Morgan et al, 1992). The fatty acid compositions of rapeseed and fish oils are characterised by a number of factors of relevance to human health recommendations (BNF, 1992). Thus, rapeseed oil contains a low content of saturates, a moderate content of linoleic acid and a high content of α-linolenic acid whilst fish oil contains high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Although benefiting the nutritional value of meat/fat, the feeding of increased levels of highly polyunsaturated fatty acids has the potential, in theory at least, of adversely affecting organoleptic and various physical properties. Such adverse effects could be manifested during and/or after the preparation and cooking of the meat or meat products at which times the oxidative degradation of fatty acids is maximised. The inclusion of dietary vitamin E has a range of beneficial effects on meat quality principally due to its antioxidant effects. The present experiment was an attempt to optimise the fatty acid composition of pork and pork products for human health purposes whilst not adversely affecting factors controlling consumer acceptability.

The aim of this study was to evaluate the effects of basal dietary supplementation with linseed and linseed plus vitamin E in Marchigiana young bulls on the instrumental color, oxidative stability, and fatty acid composition of beef steaks with and without treatment with a blend of essential oils (oregano and rosemary) after storage times of 0, 3, 6, and 9 days. The fatty acid composition was evaluated in meat after 0 and 9 days of storage. No variation in the fatty acid composition of each type of meat was observed after storage. The use of dietary linseed and vitamin E, compared with linseed alone, significantly improved the oxidative stability, lightness (L*), and redness (a*) of the meat. A higher degree of oxidation was observed in meat samples from animals in the group fed linseed (L) followed by the control group (C) and the group fed linseed and vitamin E (LE). Moreover, the essential oils treatment (O) exerts a significant effect on beef oxidative stability of the group LE more than groups C and L during storage. The fatty acid composition of the meat was also affected by the diet: levels of healthful fatty acids (PUFA, n-3 PUFA, and CLA) were higher in meat from the groups that received linseed than the control group. Our results suggest that dietary vitamin E and treatment with essential oils are effective approaches to preserving the stability of beef cattle receiving a diet enriched in unsaturated fatty acids for up to 9 days of storage.
