Öğe The Effect of Clove and Cinnamon on Some Physicochemical Properties of Sucuk Produced by Different Animal Fat Types(UNIV NAMIK KEMAL, 2017) Unal, Kubra; Karakaya, MustafaIn this research, the effect of clove and cinnamon on some properties of sucuk produced by tallow fat, subcutaneous fat, tail fat and equal mixtures of those (mixed fat) was investigated. Some physical and chemical analyses (moisture, protein, fat, pH, water activity (a(w)), lactic acid, free fatty acid) of sucuk samples were evaluated. It was also performed thiobarbituric acid (TBA) value, DPPH (2,2-diphenyl-1-picrylhydrazyl) activity and fatty acid composition. The highest DPPH activity was determined in clove and cinnamon group according to the control group. Adding clove at concentration of 0,2% decreased TBA values (0,39 mg malonaldehyde/kg) of sucuk samples. The highest total saturated fatty acid composition amount was found in mixed sucuk group (p<0,05). Control and subcutaneous sucuk groups had the lowest total saturated and the highest unsaturated fatty acid composition amount. However, the lowest total unsaturated fatty acid composition amount was determined in mixed, tail and tallow fat sucuk group (p<0,05).Öğe The effect of different thawing methods on quality parameters of frozen mussels and shrimp meats(2019) Ceylan, Zafer; Unal, KubraIn this study, the effects of different thawing methods on microbial, physical and sensory quality of frozen mussels and shrimp samples were investigated. The thawing process was carried out at the refrigerator temperature (B4: 41ºC), at room temperature (O22: 221ºC), in warm water (I30: 301ºC) and in hot water (S55: 55 1ºC). Total mesophilic bacteria counts in mussel and shrimp meat samples were found with the lowest in B4 (2,74 log KOB / g) and S55 (3,35 log KOB / g) groups, the highest values were found in the I30 group in both samples. In terms of psychrophilic bacteria, the lowest results were determined in the groups thawed by S55 method. According to the color results; the lowest L* value in mussels and shrimp meat was determined in I30 group, the b* value associated with oxidation was found to be highest in mussel meat samples in O22 and in shrimp meat samples in B4 group. The lowest water activity value was found in mussel meat in B4 and in shrimp in O22 groups. According to sensory analysis results; the highest overall acceptability score was determined in the thawed in refrigerator in both samples. Consequently, when all the quality parameters were evaluated, it was determined that thawing in the refrigerator and hot water was the best method.Öğe Effect of Oregano, Sage and Rosemary Essential Oils on Lipid Oxidation and Color Properties of Minced Beef During Refrigerated Storage(TAYLOR & FRANCIS LTD, 2014) Unal, Kubra; Babaoglu, Ali Samet; Karakaya, MustafaThe effects of oregano, sage and rosemary essential oils on lipid oxidation and color properties of minced beef during refrigerated storage for 10 days were investigated. Minced meats were divided into four treatment groups and were homogenized with 2 % (w/w) of oregano essential oil, sage essential oil and rosemary essential oil separately. Samples in the control treatment had no essential oils added. The results of the present study show that adding essential oils protect minced beef against lipid oxidation and extend the shelf-life of minced meat during refrigerated storage. Oregano, rosemary and sage essential oil treatments demonstrate higher antioxidant activity and L* values when compared to control treatment. Oregano and sage treatment have lower oxidation of minced beef than rosemary and control treatment. Oregano essential oil showed the highest antioxidant activity, when compared to the control and the others groups. In conclusion, the best antioxidative effects were obtained from oregano essential oil.Öğe Effect of sonication time on technological and emulsification properties of spent chicken breast and thigh meats(DEUTSCHER FACHVERLAG GMBH, 2015) Unal, Kubra; Karakaya, Mustafa[Abstract not Available]
