On this research, the effects of cooking by convection oven and cooking by sous-vide method on the physicochemical, textural, sensorial and microbiological of gluteus medius cuts were investigated. For the sous-vide method, the meat was vacuumed sealed in special packaging material (Mylar®Cook) before being stored at + 1 °C for 0, 15, and 30 days. The samples cooked with the sous-vide method had higher moisture content (P < 0.001) and lower cooking loss than oven roasted samples. TBARS content was affected by cooking method (P < 0.01) and storage time (P < 0.01). The 2-thiobarbituric acid reactive substances (TBARS) values of the convection oven samples were higher than those cooked with sous-vide method. The WBSF values were affected by the cooking methods. The samples cooking with oven significantly lower shear (P < 0.0001) force values than those for the sous-vide method. Samples cooked by the convection oven had higher L* (lightness), a* (redness), b* (yellowness) than the cooked with sous-vide method (P < 0.0001). The sliced meat samples cooked by oven were given higher sensory ratings than those cooked by sous-vide except texture scores.Practical Application: Roasting and sous-vide cooking are the two most common cooking methods employed in restaurants and in the catering industry. Cooking methods affect various quality characteristics of meat like as yield, tenderness, juiciness, flavor and palatability of samples. Oncreasing sales volume and new consumer demands in the food industry suggest that cook in bag products are growing in popularity as well as consumer satisfaction along with acceptable quality and cost.

Raw hazelnut milk were used to develop new plant-based fermented product using commercial starter mix containing Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus strains in order to address the current demand for health promoting and functional plant-based dairy-like products. The pH, titratable acidity (TA), serum separation (SS), protein content, fat content and ash content of fermented product were found to be 4.95, 1.25 g lactic acid/ 100 mL, 28.00%, 2.60%, 7.03% and 0.66%, respectively. Fermented hazelnut milk demonstrated non-Newtonian pseudoplastic flow behavior and it's structure was more predominantly elastic than viscous. Sensory analysis showed that some attributes of fermented hazelnut milk such as color, aroma, consistency, typical yoghurt odor and overall acceptability were less appreciated than Ayran (commercial cow milk yogurt drink) whereas some other attributes were found as satisfying.

In this research, Erzincan Tulum cheese was packaged in its original packaging material, the skin bag, small intestine, and appendix to observe the changes in its physical, chemical, and textural properties during storage day. Lactic acid% values increased in all Tulum cheeses throughout storage stage. At the end of the storage period, the highest value was determined in the sample filled in the small intestine (20.10%). All fatty acid values were increased, and the highest increase was identified in oleic acid (C 18:1) (skin bag 2.18%), linoleic acid (18:2) (appendix 0.41%), and palmitic acid (C 16:0) (small intestine 0.34%), respectively. All organic acids increased in stored sample. The highest increase among organic acids was determined to be 4.47% in lactic acid. As a result of the Texture Profile Analyses (TPA), the hardness, and adhesiveness of Tulum cheeses increased during storage periods, whereas the springiness, cohesiveness, and chewiness values decreased. Gumminess value declined in the sample filled into the appendix (with a value of 36.01), whereas it increased in the other two samples. The highest increase in hardness values was 2,520.27 N at given storage time was in the samples filled into appendix while the highest adhesive values of −49.82 were determined in the sample filled into small intestine.
