  • To identify correlation between fresh meat and processed meat products, we performed canonical correlation analysis (CCA) to predict the relationship between pork supply and meat product production in Korea. Results of CCA showed a canonical correlation of 0.8576 in the first canonical pair (p<0.01). The production of meat products showed the highest correlation with pork import but the lowest correlation with the production of domestic pork. Although Korean consumer preferred meat products produced by fresh domestic pork, inexpensively imported pork with high share in meat products was supplied in the market. Therefore, securing domestically produced raw meat is important for expanding consumption of domestic meat products. Results of this study suggest that meat processor and pig producer can achieve the $6^{th}$ industrialization by combining the production of raw pork materials, meat processing, and sales service.

  • This experiment was carried out to evaluate the tenderness of meat and it''s correlation with other carcass traits of Hanwoo steers. The significantly (p<0.01) higher mastication and shearing were observed in boiled meat than in the raw meat but the coefficient of variations were greater in raw meat than in boiled meat. The correlation between raw and boiled meat for shearing and penetration were positive and significant (p<0.01). Negative and significant correlations were observed between mastication and eye muscle area (p<0.05) and also between shearing and cooking loss (p<0.01) in raw meat whereas, penetration in raw meat was positively and significantly (p<0.05) correlated with age of the steers. Shearing in boiled meat negatively and significantly correlated with age (p<0.05), carcass weight (p<0.01), back fat thickness (p<0.01) as well as muscle score (p<0.01). The pH was not significantly correlated with tenderness in both raw and boiled meat. There were possibilities that the tenderness of boiled meat could be predicted from the raw meat.

  • Tenderness is the most important meat quality trait, which is determined by intracellular environment and extracellular matrix. Particularly, specific protein degradation and protein modification can disrupt the architecture and integrity of muscle cells so that improves the meat tenderness. Endogenous proteolytic systems are responsible for modifying proteinases as well as the meat tenderization. Abundant evidence has testified that calpains (CAPNs) including calpain I (CAPN1) and calpastatin (CAST) have the closest relationship with tenderness in livestock. They are involved in a wide range of physiological processes including muscle growth and differentiation, pathological conditions and post-mortem meat aging. Whereas, Calpain3 (CAPN3) has been established as an important activating enzyme specifically expressed in livestock's skeletal muscle, but its role in domestic animals meat tenderization remains controversial. In this review, we summarize the role of CAPN1, calpain II (CAPN2) and CAST in post-mortem meat tenderization, and analyse the relationship between CAPN3 and tenderness in domestic animals. Besides, the possible mechanism affecting post-mortem meat aging and improving meat tenderization, and current possible causes responsible for divergence (whether CAPN3 contributes to animal meat tenderization or not) are inferred. Only the possible mechanism of CAPN3 in meat tenderization has been confirmed, while its exact role still needs to be studied further.

  • Livestock is considered as one of the most important segments in agriculture since animal husbandry was practiced for centuries as a backyard system by rural families. Livestock plays as a powerful tool in rural development where meat industry contributes a dominant part. Meat and meat products become a vital component in the diet, which had been one of the main protein sources traditionally as well. The development in the livestock and meat industry of Sri Lanka basically depends upon religious, cultural, and economic factors. There is a growing demand for processed meat products in Sri Lankan urban culture and several large scale processors entered the business during the past few decades. The consumption of meat and meat products shows an upward trend in Sri Lanka during the last decade and is anticipated to increase further in future. The growth potential of the local meat industry is considerably high owing to the improvement of the market and consumer perception. The present status, trends, and future prospects for the Sri Lankan meat industry with respect to production, consumption, processing, marketing, and improvement are discussed in this review.

  • The objective of this study was to explore the potential of front face fluorescence spectroscopy (FFFS) as rapid, non-destructive and inclusive technique along with multi-variate analysis for predicting meat adulteration. For this purpose (FFFS) was used to discriminate pure minced beef meat and adulterated minced beef meat containing (1%, 2%, 3%, 4%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%) of chicken meat as an adulterant in uncooked beef meat samples. Fixed excitation (290 nm, 322 nm, and 340 nm) and fixed emission (410 nm) wavelengths were used for performing analysis. Fluorescence spectra were acquired from pure and adulterated meat samples to differentiate pure and binary mixtures of meat samples. Principle component analysis, partial least square regression and hierarchical cluster analysis were used as chemometric tools to find out the information from spectral data. These chemometric tools predict adulteration in minced beef meat up to 10% chicken meat but are not good in distinguishing adulteration level from 1% to 5%. The results of this research provide baseline for future work for generating spectral libraries using larger datasets for on-line detection of meat authenticity by using fluorescence spectroscopy.

  • The objective of this study was to evaluate the causal relationships among environmental belief, ambivalence, subjective norm, attitude and meat consumption behavior. A total of 318 questionnaires were completed. A structural equation model was employed to assess the causal effects of constructs. The results of the study demonstrated that the structural analysis results for the data also indicated excellent model fit. The effects of environmental belief, ambivalence, and subjective norm on attitude were statistically significant. The effects of environmental belief, subjective norm and attitude on meat consumption were statistically significant. The effects of attitude on intention were statistically significant. As had been expected, intention exerted a significant effect on meat consumption. Moreover, environmental belief and ambivalence exerted significant indirect effects on meat consumption through attitude. Subjective norm exerted a significant indirect effect on meat consumption through attitude and intention. Subjective norm also exerted a significant indirect effect on intention through attitude. In developing and testing conceptual models which integrate the relationship among behavioral belief, attitude variable, behavioral intention and meat consumption, this study may approach a deeper understanding of the complex relationship among meat consumption behavior-related variables. Greater understanding of the complex relationship among meat consumption behavior-related variables can improve the practical or managerial diagnosis of the problem and opportunities for different marketing strategies including meat production and meat product development and marketing communication.

  • The present study was carried out to evaluate the nutritional quality of rabbit meat protein. The composition of amino acids contained in rabbit meat was compared with those of other animal meats such as beef, pork and chicken. Also included in this study was the question whether the cooking and storage conditions affect the amino acid composition and the pepsindigestibility of rabbit meat protein. The results are summarized as follows: 1. The large variation observed from sample to sample of EAA (essential amino acid) composition in rabbit meat was found to be an interesting but peculiar property of rabbit meat protein. The most limiting amino acid of rabbit meat protein was phenylalanine, whereas methionine was the first limiting amino acid of both beef and pork proteins. Chemical scores of various meat proteins were 68, 65, 66, and 74 for rabbit meat, beef, pork, and chicken respectively. 2. In pan roasting, the EAA damaged most by heat was methionine (15%). When cooked after two months of frozen storage, lysine decreased most. 3. Higher pepsin digestibility was obtained by cooking rabbit meat after seasoned in alcohol, ginger juice, and other spices compared with various other cooking conditions without seasoning. The pepsin digestibility value was even higher for the seasoned meat than for the raw meat. 4. Among various meats tested the rabbit meat showed the lowest pepsin digestibility. 5. A simple measurement of released methionine could be used to determine relative digestibility instead of measuring $NH_2-N$ content after pepsin digestion. From all the results obtained in this study it can be concluded that rabbit meat is a good Protein food item when used fresh and stored properly to prevent rancidity problems. It is suggested to study further the peroxidation effect of unsaturated fatty acids on protein quality. This study was supported by the Ministry of Science and Technology in Korea.

  • The objectives of this study were to nutritionally evaluate Korean traditional fermentation food, Doenjang, and compare the nutrients in fish/meat-Doenjang and herb/fish/meat-Doenjang. In Doenjang, sugar, protein, fat, dietary fiber, and minerals, such as sodium and calcium, were analyzed using HPLC and the ICP analysis method authorized by the Korean Food Standards Codex. Doenjang is known to prevent arteriosclerosis, cancer and hypertension, and to aid liver function, as well as serving as a protein source. Doenjang, fish/meat Doenjang, and wild-herb/fish/meat Doenjang were made according to the original recipes in antique cookbooks. The highest levels of calories, carbohydrates, and sugar were contained in wild-herb/fish/meat Doenjang. Carbohydrate in the fish/meat Doenjang was higher than in ordinary Doenjang, and ordinary Doenjang had the lowest amount of sugar. Fat was shown to be the most abundant in fish/meat Doenjang, and the least abundant in ordinary Doenjang. Fish/meat Doenjang contained the most Na content, while wild-herb/fish/meat Doenjang had the lowest Na content. In terms of dietary fiber, ordinary Doenjang contained the most, while a wild-herb/fish/meat Doenjang contained the least. Ca content was shown to be most abundant in Doenjang, and the least abundant in fish/meat Doenjang.

  • The interaction of plasma with liquid generates nitrogen species including nitrite (NO2). Therefore, the color developing capacity of plasma-treated water (PTW) as a nitrite source for meat curing was investigated in this study. PTW, which is generated by surface dielectric barrier discharge in air, and the increase of plasma treatment time resulted in increase of nitrite concentration in PTW. The PTW used in this study contains 46 ppm nitrite after plasma treatment for 30 min. To evaluate the effect of PTW on the cured meat color, meat batters were prepared under three different conditions (control, non-cured meat batter; PTW, meat batter cured with PTW; Sodium nitrite, meat batter cured with sodium nitrite). The meat batters were vacuum-packaged and cooked in a water-bath at 80℃ for 30 min. The typical color of cured meat developed in cooked meat batter treated with sodium nitrite or PTW. The lightness (L*) and yellowness (b*) values were similar in all conditions, whereas, the redness (a*) values of cooked meat batter with PTW and sodium nitrite (p<0.05) were significantly higher than the control. These data indicate that PTW can be used as a nitrite source in the curing process of meat without addition of other nitrite sources.

  • 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.
