Packaging methods (vacuum packaging and modified atmosphere packaging) allow for maintaining high-quality meat during a long period of storage (30 d) under refrigeration conditions. An interaction between the storage time, packaging method, and mesophilic aerobic bacteria and coliform counts was observed. Storage time affected the number of aerobic psychrotrophic bacteria, redness, pH, shear force value, and desirability of the meat's aroma and taste.

The lipid analysis of commercial lamb meat, from the two main Moroccan production areas Middle Atlas and highlands of eastern Morocco, was conducted. The fatty acid profiles of the sheep meats analyzed showed polyunsaturated fatty acid richness, balanced polyunsaturated / saturated fatty acid ratios, and desirable fatty acid richness. The present study provides new insights into the nutritional value of intramuscular fat of four Moroccan sheep meats reared in an outdoor production system.

Recently, consumers have been seeking natural and healthy products such as meat rich in polyunsaturated fatty acids, beneficial for health with decreasing the saturated fatty acids. Then, to enhance the meat quality, some nutritional strategies were considered such as using the residues of aromatic and medicinal plants. Then, the use of rosemary residues in lamb feeding increased the polyunsaturated fatty acid, n-6 and n-3 contents and reduced the saturation index in muscles and adipose tissues.

In an experiment the longissimus lumborum and gluteus medius muscles were collected from lambs of two genotypes to analyse physico-chemical traits, fatty acid profile, taurine, carnosine, and L-carnitine. Results showed a greater impact of the lamb’s genotype on physical traits of meat than on its chemical composition and content of bioactive components. Muscle type had an effect on meat colour; collagen content; fatty acid profile; and the amount of taurine, carnosine, and L-carnitine.

This study aimed to assess drip loss measurements in mutton taken by different methods (EZ and bag, BM) and their relationship with pH values and color. Mutton samples originating from 20 ewes of Istrian sheep were used to examine the effect of the method on drip loss after 24 and 48 h. EZ and BM method in mutton do not provide equivalent results for measuring drip loss. Comparisons of the results obtained with different methods should be avoided or at least performed with great precaution.
