토종닭과 broiler의 고기 맛에 관계하는 정미성분의 함량을 측정하여 다음과 같은 결과를 얻었다. 두 종 모두에서 유리아미노산 중 고기 특유의 풍미를 나타내는 carnosine의 함량이 가장 많았고 정미에 크게 영향을 미치는 glutamic acid함량도 많은 것으로 나타났다. Carnosine은 가슴살 그리고 28주령의 토종 닭고기에서 가장 많았으며, 다리살에 있어서는 6주령 이상의 토종 닭고기에 많았다. Glutamic acid함량은 다리살 그리고 11주령 이상의 토종 닭고기에서 많았고, 가슴살에 있어서는 6주령 이상의 토종 닭고기에 더 많은 것으로 나타났다. 도살 후 4$^{\circ}C$에서 48시간 저장한 경우 유리아미노산은 carnosine을 제외하고 대부분 증가했으며, carnosine은 도살 직후와 동일하게 가슴살에서는 28주령의 토종 닭고기에, 다리 살에서는 11주령 이상의 토종 닭고기에 더 많았다. Glutamic aicd는 가슴살에 있어서는 11주령 이상의 토종 닭고기에, 다리살에는 6주령 이상의 토종 닭고기에 더 많았다. 또한 좋지 않은 맛을 나타내는 아미노산의 합에 대한 좋은 맛을 나타내는 아미노산의 합의 비에 있어서도 11주령 이상의 토종 닭고기에 더 높게 나타났으며 , IMP의 경우 전반적으로 15주령 이상의 토종 닭고기 에 많은 것으로 나타났다. 따라서 유리아미노산 및 핵산관련물질의 결과로 미루어 11주령이상의 토종 닭고기가 육용의 broiler고기보다 정미성분이 많아 맛에 있어 우수함을 나타내고 있다.

본 연구는 몽골의 돼지고기 시장을 분석하고 국내산 돼지고기의 대몽골 수출 지속 가능성을 모색하는데 그 목적이 있는바, 연구결과를 요약하면 다음과 같다. 첫째, 몽골의 돼지고기 소비는 생산량이 부족하여 주로 수입에 의존하고 있으며 돼지고기 가격을 100으로 가정할 때 타 육류의 소비자 가격은 쇠고기 63, 닭고기 100, 양고기 54로서 돼지고기가 비싼 편이다. 둘째, 몽골에서 수입을 원하는 부위는 가격이 저렴한 부위를 요구하기 때문에 국내산 돼지고기 수출 가능부위는 돼지지방(육가공용)과 후지이다. 셋째, 현재 돼지고기 가격의 상승으로 수출물량은 거의 없는 실정이나 국내 돼지고기 시장여건이 악화될 경우에 대비하여 향후 수출할 수 있는 여지를 남겨 놓아야 한다는 측면에서 한국산 돼지고기 수출시장으로서의 역할이 지속되어야 할 것으로 판단된다.

In this study, we investigated the quality characteristics of noodles supplemented with lyophilized leg-meat powder from the red snow crab, Chionoecetes japonicus (CP). The noodles were prepared by adding 0, 2, 4, 6, 8, 10% of CP on a wheat-flour basis. The ash, crude protein and crude lipid contents of noodles increased with increasing CP content. The cooked weight, volume and water absorption values of noodles decreased, whereas the turbidity increased, with increasing CP content. The L values of the noodles decreased with increasing CP content, whereas the a and b color values increased. The hardness, gumminess and chewiness values increased with increasing CP content increased, while springiness and cohesiveness showed no significant differences among the groups. In the sensory evaluation, cooked noodles with 4-6% CP had greater overall acceptability than the noodles with other CP levels.

In this study, we investigated the quality characteristics of madeleine combined with lyophilized red snow crab Chionoecetes japonicus leg-meat powder (CM). The madeleine was prepared by the addition of wheat flour containing 0, 1, 5, 10, 15 and 20% concentrations of CM. Moisture content, pH, and baking loss rate did not differ significantly among groups. Light coloration significantly decreased in a dose-dependent manner, while red and yellow coloration significantly increased. Hardness, chewiness and gumminess significantly increased in a dose-dependent manner, while cohesiveness, springiness and adhesiveness did not differ from CON (madeleine containing 0% CM). In terms of sensory characteristics, appearance and color did not differ compared to CON, while taste, flavor and overall preference increased in a dose-dependent manner, with CM10 having the highest score among the groups. The present study assesses the potential of this improved formula as a convenience food.

An experiment was conducted with three hundred and twenty broiler chickens to evaluate the influence of supplementation of probiotic on growth, microbiological status and carcass quality of chickens. The probiotic contained similar proportions of six strains of variable organisms namely Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium bifidum, Aspergillus oryzae, Streptococcus faecium and Torulopsis sps and was fed at 100 mg/kg diet. The body weight and feed conversion of probiotic fed groups were superior (p<0.05) compared to the control group in the 4th, 5th and 6th weeks. The chickens fed the diet with probiotic had lower (p<0.05) numbers of coliforms and Campylobacter than chickens fed the control diet. All chickens' carcasses on the control diet were positive for Salmonella while only 16 of the 40 carcasses were positive from chickens fed diets containing probiotic. The leg and breast meat of probiotic fed chickens were higher (p<0.05) in moisture, protein and ash, and lower in fat as compared to the leg and breast meat of control chickens.

This study presents the estimates of heritabilities of body measurement traits and carcass traits, and genetic and phenotypic correlations of those traits for crossbred pigs in Korea. Body and ultrasound (A mode: Piglog 105) measurements in 221 pigs including body weight, length, height and width, three back fat thickness at the points of 4th, 14th rib and chine bone, eye muscle area and lean meat percent were collected at the ages of 70, 145 and 180 days and then slaughtered to measure carcass weight, back fat, belly, collar butt, spare rib, picnic shoulder, hind leg, loin, tenderloin, lean meat yield and intramuscular rough fat content in loin. Genetic analysis was done using a multi-trait animal model. Heritabilties of the body measurements were ranged from 0.331 to 0.559 and three measurements of back fat thickness were also high as range varying from 0.402 to 0.475 for the ages of 145 and 180 days. However, eye muscle area was moderate (0.296) at the age of 180 days. Heritabilities of retail cut yields were also high as ranged from 0.387 to 0.474 and of IMF content in loin was 0.499. Heritabilities of the cut percent traits were ranged from 0.249 to 0.488. Important positive genetic and phenotypic correlations were noted for all carcass yield traits (0.298 to 0.875 and 0.432 to 0.922, respectively). IMF showed low negative genetic correlations with carcass yield traits, such as carcass weight, picnic shoulder, hind leg, loin, tenderloin and lean meat yield whereas low positive genetic correlations with back fat, belly, collar butt and spare rib. Loin, tenderloin and lean meat percent showed negative genetic correlations with carcass weight, back fat thickness, collar butt, spare rib and picnic shoulder percent. The four body measurements at the ages of 70, 145 and 180 days had positive genetic correlations with belly, shoulder butt, spare rib, picnic shoulder and hind leg percent, but negative genetic correlations were shown with loin and tenderloin percent except body measurements at 70 days. The results suggest that carcass yield are negatively correlated with intramuscular fat content, which is a major factor deciding pork quality and the yield of loin and tenderloin are not increased as much as increase in body size. However, the proportions of belly and collar butt are increased with the body size. In conclusion, selection strategy should be designed according to the preference on composition of carcass in each country.

An experiment was conducted to evaluate the growth performance and meat quality traits of broilers fed a diet supplemented with dry-ground curry leaves (Murraya koenigii). A total of 750 one-day-old broiler chicks (Cobbs 500) were arranged in the experiment with a completely randomized design and allotted to one of five treatments, with $T_1-Control$ and $T_2-T_5$ curry leaves powder levels (i.e., 0.3%, 0.6%, 0.9% and 1.2%, respectively). The initial body weights, final body weights and daily feed intake were measured over an experimental period of 32 days. At the conclusion of the experiment, the carcass weights and meat quality parameters were measured. The birds fed diets supplemented with curry leaves powder had a higher weight gain (P<0.05; ADG), improved feed conversion ratio (P<0.05; FCR) and lower mortality (P<0.05) rates compared to the birds in the control group. Nonetheless, there was no difference (P>0.05) in feed intake among the dietary treatments. Similarly, supplementation of curry leaves powder had no effect (P>0.05) on the proportions of the carcass, leg meat and drumstick. No differences were (P>0.05) observed in cooking loss or the pH of meat from broilers fed the curry leaves supplemented diet. However, curry leaf supplementation affected (P<0.05) the meat water holding capacity. A sensory evaluation showed higher levels of taste and tenderness in meat from broilers fed with curry leaves powder. In conclusion, our results suggested that curry leaves powder improved the growth performance of broilers, with a lower incidence of mortality and improvement of some meat qualities.

In order to evaluate the maximal storable period of the raw crab for a non-thermal muscle separation, the quality changes of the leg meat of red snow crab (Chionoecetes japonicus) during freeze storage were investigated. Fresh red snow crabs were stored at $-20^{\circ}C$ for 7 weeks, and the leg muscle was separated by a no heating separation (NHS) method every week. During the storage, considerable loss of the leg muscle did not occur and microbiological risk was very low. In contrast, discoloration appeared at 2-week storage on around carapace and the leg muscle turned yellow at storage 3-week. In physiochemical parameters, protein and free amino acids gradually decreased with storage time, expected that proteolytic enzymes still activated at $-20^{\circ}C$. At 4-week storage, the sensory acceptance dropped down below point 4 as low as inedible and notable inflection points in pH and acidity were observed. The volatile base nitrogen was low, though a little increase was recorded. These results suggested that the maximal storable period at $-20^{\circ}C$ of the raw material was within 2 weeks and it was depended on external factor such as the discoloration. The present study might be referred as basic data for approaches to solve quality loss occurred in non-thermal muscle separation.

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.
