Edible oil marination in broiler meat for short term preservation

The aim of this study was to evaluate the quality and shelf life of raw broiler meat incorporated with soybean, mustard and flax seed oil under refrigerated storage at 4±1ºC. Meat samples were divided into four different batches i.e. T0 = (Control group), T1= (1% Soybean oil), T2= (1% mustard oil), T3= (1% flax seed oil). After 0, 7 and 14 days of storage, the samples were tested for physicochemical characteristics (pH, water holding capacity), oxidative stability (TBARS), sensory properties (color) and microbiological counts (TVC, TCC, and TYMC), proximate analysis (DM, EE, CP, Ash). When compared to control samples, the addition of oils had a significant (P<0.05) effect on physicochemical characteristics, oxidative stability, microbiological and sensory quality. During the whole storage process, the pH and water holding capacity in batches of T1 , T2 and T3 were considerably lower (P<0.05) than in the control group. Among all the treatment batches, the mustard oil (T2 ) had significantly lower (P<0.01) TBARS values during storage. The T2 treatment showed comparatively lower values of viable count, coliform count and yeast-mold count throughout the storage period. The color of the T0 sample was far superior than other treatments. The T2 treatment had the most preferred good odor, whereas the control group had the least. Based on the findings of this study, it is possible to conclude that mustard oil may be used for meat marination and preservation and extending the shelf life of stored meat rather than soybean and flax seed oil. According to the findings of this comparative study of different types of oil marination, mustard oil could be used in the preservation of raw broiler meat at refrigerated storage.
