Colour Stability, Fatty Acid Profile, and Lipid Oxidation in Meat Stored in Modified Atmosphere Packaging from Light Lambs Fed with Concentrate with Carob Pulp (Ceratonia siliqua L.)

There is a growing interest in using by-products rich polyphenols, such as carob pulp (Cp, Ceratonia siliqua L.), dietary source of antioxidants for animals. This study assesses the effects including Cp lambs’ diet and meat display time (0, 7, 9, 11 days) modified atmosphere packaging on colour, fatty acid (FA) composition, tocopherol levels, lipid oxidation values Semimembranosus muscle 40 light lambs. The lambs were fed with concentrates supplemented increasing levels 150, 300 g/kg) 45 days before slaughter. Metmyoglobin (MMb) malondialdehyde (MDA) contents increased linearly (p < 0.05), regardless > 0.05). At display, MMb (28 ± 0.8%) MDA (0.6 0.1 mg MDA/kg meat) remained within acceptable limits. α-tocopherol content was lower 30% group Total saturated monounsaturated FA (934 64 823 65 mg/100 g meat, respectively) did not differ significantly among groups. However, from showed reduced branched-chain FAs, while polyunsaturated FAs 0.05) compared to control inclusion lamb’s diet, up 30%, lead deterioration improved certain quality parameters, healthier profile. These findings highlight Cp’s potential an alternative antioxidant animal diets.
