Chemical Indicators of Ostrich Struthio camelus Linnaeus, 1758 Meat Burger Prepared by Adding Different Fat Levels During Frozen Storage

Abstract: This study included preparation of ostrich meat burger with different levels of ostrich fat. The first treatment was free-fat and the second treatment 5% fat, the third treatment was 10% fat, the fourth and the fifth was 15% and 20% respectively and stored in 18 ± 2 co for 120 days. Changes in chemical indicators were studied including peroxide value (PV), thiobarbituric acid (TBA), free fatty acids (FFA) and total volatile nitrogen (TVN) during storage periods 1, 30, 60, 90 and 120 days. The results showed th… Show more

“…It was observed that there was a significant increase (P ≤ 0.05) in the percentage change in weight as a result of cooking with the progression of the storage period, as it reached 46.555% in the control treatment, while it reached 34.325% in the chia flour treatment. The reason for the high percentage of loss is that slow freezing leads to the formation of large ice crystals during freezing and the thawing of these crystals and their loss in the form of water droplets during defrosting and cooking the meat, in addition to the loss of moisture from the surface of the meat during the storage period [15]. It can be noted from the results in Table (3) that the substitution has a significant effect (P ≤ 0.05) on the change in thickness as a result of cooking beef burgers.…”
