Objective: Sous-vide cooking offers several advantages for poultry meat, including enhanced tenderness, reduced cooking loss, and improved product yield. However, in duck meat, there are challenges associated with using the sous-vide method. The prolonged cooking time at low temperatures can lead to unstable microbial and oxidative stabilities. Thus, we aimed to assess how varying sous-vide cooking temperatures and durations affect the physicochemical and microbial characteristics of duck breast meat, with the goal of identifying an optimal cooking condition. Methods: Duck breast meat (Anas platyrhynchos) aged 42 days and with an average weight of 1,400±50 g, underwent cooking under various conditions (ranging from 50℃ to 80℃) for either 60 or 180 min. Then, physicochemical, microbial, and microstructural properties of the cooked duck breast meat were assessed. Results: Different cooking conditions affected the quality attributes of the meat. The cooking loss, lightness, yellowness, Hue angle, whiteness, and thiobarbituric acid reactive substance (TBARS) values of the duck breast meat increased with the increase in cooking temperature and time. In contrast, the redness and chroma values decreased with the increase in cooking temperature and time. Cooking of samples higher than 60℃ increased the volatile basic nitrogen contents and TBARS. Microbial analysis revealed the presence of Escherichia coli and Coliform only in the samples cooked at 50℃ and raw meat. Cooking at lower temperature and shorter time increased the tenderness of the meat. Microstructure analysis showed that the contraction of myofibrils and meat density increased upon increasing the cooking temperature and time. Conclusion: Our data indicate that the optimal sous-vide method for duck breast meat was cooking at 60℃ for 60 min. This temperature and time conditions showed good texture properties and microbial stability, and low level of TBARS of the duck breast meat.

In this study kinds of Lamb cooking and preservation and the ingredients of lamb cooking are surveyed through the references written from 1670 to 1943. The lamb cooking found in the literature totaled to more than 53. They can be classified into fourteen different groups according to their processing features which as follows: Salnum and Pyunyuk(boiled and slices of boiled), Kui(roasted), Chim(steamed), Whe(raw meat), Hounjae(smoking), Po(dried), Juk(gruel), Tang(soup), Sundae(stuffed small interstines), Jokpyun(jellied foot), Jungol(happiness pot), Sikhae(salt+meat+malt), Oumjang(salted meat), Kunjo(dried). Korean lamb cooking methods were primarily adopted from Mogolia in late Korea Dynasty but they had unique characteristics different from Mongolian ones. Furthermore, they were creatively applied to other meat cooking such as beef, pork and dog. About twenty one ingredients were mainly used in lamb cooking, including fresh meat, ribs, breast, heart, liver and the like. In particular, most popularly used ones were fresh meat and the heart in internal organs, which coincide with the main ingredients in beef cooking of today. The number of seasoning used in lamb cooking was twelve and especially salt, vineger, ginger and stone leek were most commonly used ones. Fourteen other addition were put into lamb cooking and the rice(Korean) wine was the most frequently used addition.

Objective: The objective of this study was to evaluate the effects of four different cooking techniques viz: boiling, grilling, microwave, and frying; on the physicochemical characteristics of camel meat. Methods: Protein composition and their degradation as well as biochemical and textural changes of camel meat as influenced by cooking methods were investigated. Results: The highest cooking loss (52.61%) was reported in microwaved samples while grilled samples showed the lowest cooking loss (44.98%). The microwaved samples showed the highest levels of lipid oxidation as measured by thiobarbituric acid reactive substances, while boiled samples showed the lowest levels (4.5 mg/kg). Protein solubility, total collagen, and soluble collagen content were highest in boiled samples. Boiled camel meat had lower hardness values compared to the other treated samples. Consequently, boiling was the more suitable cooking technique for producing camel meat with a reduced hardness value and lower lipid oxidation level. Conclusion: The camel meat industry and camel meat consumer can benefit from this research by improving their commercial viability and making consumers aware about the effects of cooking procedures on the quality of camel meat. The results of this study will be of significance to researchers and readers who are working on the processing and quality of camel meat.

In most developing countries consumers purchase retail cuts from hot carcasses and prepare traditional meat products as per their convenience and requirements. In this study, effects of different post mortem handling practices on quality of meat curry from culled sheep meat have been studied. After slaughter, leg cuts were subjected to nine commonly prevalent handling conditions in India viz. deboning (boning out) and cooking within 2-3 h (1), deboning immediately and cooking after 5-6 h (2), deboning after 5-6 h and cooking (3), deboning immediately, storage at $4^{\circ}C$ for 24 h and cooking (4), chilling for 24 h at $4^{\circ}C$, deboning and cooking (5), deboning after 5-6 h, storage for 24 h at $4^{\circ}C$, and cooking (6), deboning after 5-6 h, storage for 48 h at 4??C and cooking (7), deboning after 5-6 h, freezing and cooking (8), deboning after 5-6 h, storage for 24 h at $4^{\circ}C$, freezing and cooking (9). Significant differences were observed in pH, water-holding capacity, cooking loss and shear force values. Sensory scores were significantly higher in conditions (1), (5) and (9), and significantly lower in conditions (4) and (6). From the results, it was concluded that, to have the best quality product, meat should be cooked either immediately after slaughter or should be deboned just before cooking. Storage of deboned meat at refrigerated temperature must be avoided.

The objective of present study was to investigate the effect of cooking and their combinations with re-heating methods on the formation of cholesterol oxidation products (COPs) in stored chicken thigh meat. Pan roasting, steaming, oven grilling, charcoal grilling, and microwaving were used for cooking. Re-heating of samples was done using the same cooking methods or microwaving after 3 and 6 d of refrigerated storage. Cooking and re-heating resulted in reduction of crude fat and cholesterol contents of chicken thigh meat depending on storage period before re-heating. Cooking and storage period had no influence on the total amount of COPs. The highest total amount of COPs was observed in meat samples cooked by steaming and reheated by microwaving after 6 d of storage, which showed similar value to raw chicken meat stored for 6 days. However, different re-heating methods formed different types of COPs depending on storage period before re-heating. The high amount (p<0.05) of 25-hydroxycholesterol or ${\alpha}-epoxide$ was detected in meat samples reheated by steaming or microwaving at 3 or 6 d of storage after steamed cooking, respectively. As a result, the combination of steaming and re-heating with microwaving could increase the total amount of COPs in chicken thigh meat and different cooking/re-heating methods could form different types of COPs, even though no significant difference in the total amount of COPs depending on storage period.

This study was conducted to investigate the attitude of dietitians on meat products and consumption of meat products in meal service of elementary school. Eight hundred and forty two questionnaires collected from each district of the country were statistically analyzed. Dietitians showed preference of ham and packed meat to other meat products. Dietitians had a good image on meat product regarding it as a good source of protein, imported food and diversely used food for cooking. Whereas 50% and 25.8% of dietitians concerned about the high content of preservative and sodium, respectively. More than 96% of dietitians suggested the food processing company to decrease the addition of preservatives, coloring agents, color formers and sodium. Fifty nine percent of dietitians responded they would increase the consumption of meat product if it is processed to food with low sodium, low cholesterol, low fat and no persavatives. Dietitians used ham for cooking once or twice a month. The reason they used the meat product for meal service was the preference of students and readiness of meat product for cooking. The dietitian's favorite cooking method was roasting ham or sausage with vegetable. Dietitians responded the first thing they checked for purchasing meat product was the date of processing and the term of validity.

Effects of fucoxanthin (FX), a major carotenoid in algae, on lipid peroxidation and meat colour in ground chicken breast meat were investigated. FX and/or ${\alpha}$-tocopherol (Toc) were added to ground samples at a content level of 200 mg/kg. The samples were subjected to a chilling storage test before and after cooking. In the storage test before cooking, neither FX nor Toc affected the thiobarbituric acid reactive substances (TBARS) on days 1 and 6, and FX decreased the L* value and increased the a* and b* values. In the storage test after cooking, both FX and Toc decreased TBARS values on days 1 and 6. FX decreased the L* value and increased the a* and b* values, similar to what occurred in the storage test before cooking. Based on these results, we concluded that FX is a potent ingredient for improvement of the appearance and shelf life of chicken meat and its products.
