Cultured meat is one of the research areas currently in the spotlight in the agricultural and livestock industry, and refers to cells obtained from livestock that are proliferated and differentiated and processed into edible meat. These cell-cultured meats are mainly studied at the lab-scale by culturing them in flasks, and for commercial use, they are produced using scaffolds that mimic cell supports. Scaffolds are broadly divided into fiber scaffolds, hydrogels, and micro-carrier beads, and these are classified according to processing methods and materials. In particular, a scaffold is essential for mass production, which allows it to have appearance, texture, and flavor characteristics similar to meat. Because cultured meat is cultured in a state where oxygen is blocked, it may be lighter in color or produce less flavor substances than edible meat, but these can be compensated for by adding natural substances to the scaffolds or improving fat adhesion. In addition, it has the advantage of being able to express the texture characteristics of the scaffolds that make up the meat in various ways depending on the materials and manufacturing methods of the scaffolds. As a result, to increase consumers' preference for cultured meat and its similarity to edible meat, it is believed that manufacturing scaffolds taking into account the characteristics of edible meat will serve as an important factor. Therefore, continued research and interest in scaffolds is believed to be necessary.

In the year of 1998 the heads of dog raised in Korea were 1,846,411 and the number of the households raising dogs is 819,112 which means that the heads of pet dog and edible dos were 819,112 and 1,027,299, respectively, because each house raised about one pet dog and one edible dog breeder raised hundreds of dog. in 1998 the number of exported dogs came to 28 heads and that of imported dogs was 296 heads. But edible dog that was slaughtered or processed has not been reported to be exported or imported. It is known that at the Shenyang Xingshan Food Ltd in Shenyang, Chinese, 300,000 heads of dogs were rais-ed slaughtered and processed of dog meat per year, and 20% of them were exported. In Korea the cook of dog meat is a special food culture with a long history. During the Chosun dynasty dog meat had been eaten to be cooked diversely such as Gaejangkuk(a soup) Suyuk(a boiled meat) Sundae(a sausage) Kui(a roasted meat) Gaezim(a steamed meat) Nurumi(a meat roasted or fried to which lot of spice paste are added) Gaesoju(an extract) Musulju(a wine) Musuldang(a sweet cane) Now it is cooked as Bosintang(a soup) Suyuk (a boiled meat) Jeongol (boiled meat mixed with spices vegetables and water on the pot) Duruchigi(boiled meat added spice vegatasble and slightly roasted) Muchim(boiled meat added by spice and mixed) Gaesoju(an extract) with the number of recipes lessened compared with those of the old times. The reason is due to the intervention and criticism from foreign countries. But foreigner's blame for the dog meat is absurd and excessive action because Korea raises exceptional dogs which are edible.

Procyanidins, which are natural antioxidants and antimicrobials found in grapes, enhance the quality and extend the shelf life of meat. We explored the effects of edible films incorporating procyanidins on pork loin stored for various times. Procyanidins (0, 0.1, and 0.3%, w/w) were incorporated into the edible films. We assessed meat color, pH, levels of volatile basic nitrogen (VBN) and 2-thiobarbituric acid-reactive substances (TBARS), and microbial populations for 14 d. The chromaticities and pH values of pork loin wrapped in film containing procyanidins (0.1% and 0.3%) generally increased (p<0.05) with storage time. VBN and TBARS levels, and total bacterial and Escherichia coli (E. coli) counts, significantly decreased (p<0.05) in the procyanidin groups. In particular, procyanidins strongly inhibited TBARS formation. Thus, our findings suggest that edible film impregnated with procyanidins inhibits lipid oxidation and microbial growth, thereby enhancing the quality and shelf life of pork meat.

Plant-based meat analogues, edible insects, and cultured meat are promising major meat alternatives that can be used as protein sources in the future. It is also believed that the importance of meat alternatives will continue to increase because of concerns on limited sustainability of the traditional meat production system. The meat alternatives are expected to have different roles based on their different benefits and limitations. Plant-based meat analogues and edible insects can replace traditional meat as a good protein source from the perspective of nutritional value. Furthermore, plant-based meat can be made available to a wide range of consumers (e.g., as vegetarian or halal food products). However, despite ongoing technical developments, their palatability, including appearance, flavor, and texture, is still different from the consumers' standard established from livestock-based traditional meat. Meanwhile, cultured meat is the only method to produce actual animal muscle-based meat; therefore, the final product is more meat-like compared to other meat analogues. However, technical difficulties, especially in mass production and cost, remain before it can be commercialized. Nevertheless, these meat alternatives can be a part of our future protein sources while maintaining a complementary relationship with traditional meat.

The purpose of this study is to understand the evolution of food culture by applying the evolutionary mechanism to the process of forming the dog meat culture. To do this, this study first examined mutation, selection, and replication as a evolutionary mechanism by biological genes and explain the evolutionary process of food culture by applying so-called 'mime' which is a virally-transmitted cultural symbol or social idea. A meme acts as a unit for carrying cultural ideas, practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. In addition, this study also intended to use in-depth interviews on how people have diverse cultural perspectives interpret and accept edible culture of dog meat. In Korea, which was a traditional farming society, dog meat which is easier to obtain compare to beef has been chosen as an important source of protein. And this choice has been repeatedly reproduced through generations. However, the current generation's awareness of the edible culture of dog meat has changed. The meme of pet culture has been selected and replicated, and this cultural evolution will eventually lead to the culling of dog meat.

The consumer demands for quality of meats has become diverse in recent years. The present paper describes mainly the technology to improve the broiler meat quality with special reference to reducing fat contents in edible meats which is the heart of the quality constraints. Abdominal fat deposition in broilers was reduced by feeding of medium-chain triglycerides(MCT), suggesting MCT feeding is useful to produce broiler meat with low fat content. A phase feeding system to aim at improving meat quality that is mainly comprised with partial replacement of dietary protein into phase during 4∼6 weeks increased edible meat yields and reduced abdominal fat deposition and fat contents in breast and thigh meats. Whiteness of fat tissue was intensified by feeding beef tallow or lard in place of yellow grease. Feeding Phaffia yeast containing astaxanthin increased redness of breast and thigh meats and improved visual appearance of meats which may be preferential for consumers. Feeding fish oil reduced abdominal fat deposition and increased EPA and DHA contents of fat tissues. These procedures could be used for manipulation of meat quality to meet consumer demands.

The present paper reviews the findings of different research studies on the effect of natural ingredients in the Japanese quail (Coturnix coturnix japonica) diet on carcass characteristics and meat quality. The results show a relationship between the type and concentration of ingredients used in diets and carcass characteristics and meat quality. The inclusion of medicinal herbs (thyme, black seed, and mint), plants (canola), seeds (chickpea), spices (cinnamon and coriander), worms (earthworms), bee products (propolis), phytochemicals (lycopene), and edible fungi (common mushrooms) in the diet improved carcass quality characteristics compared to the control diets (basal diets). The inclusion of medicinal herbs (spearmint and green tea), spices (cinnamon), vegetables (tomato), plants (verbena and canola), seeds (marijuana), and edible fungi (oyster mushrooms) improved meat quality. In conclusion, the use of ingredients of natural origin in the diet of Japanese quail improves carcass quality characteristics and meat quality.

This study was carried out to investigate the status in weight loss yield of edible meat quality and free amino acid contents of the snow crab(Chionoectes japonicus) by steaming and various drying treat-ment. Change of body weight loss in steaming treatment sample were 20.48∼26.72% and yield of edible meat of steaming sample was higher than raw sample(p<0.05) The pH value was increased with steam-ing and drying and pH of trunk meat was more increased than leg meat. Volatile basic nitrogen(VBN) content of vacuum dried sample was highest and VBN of hot-air and freezing dried sample were about 10mg%. Content of vaccum dried sample wre 41.33 and 48,56mg%. Thirty kind of free amino acids dectected in the snow crab and changes of free amino acid in leg meat were markedly reduced by vacuum drying and the reducing ratio of leg meat by freeze drying was little. The major free amino acid of leg and trunk meat were 39.94% 46.78% respectively. The formation of flavor free amino acid in freezing dried sample were high but its hot-air aried sample were small.
