The quality attributes of thigh meat from a certified meat-type commercial Korean native chicken (WoorimatdagTM, WM) and a commercial broiler (Ross, CB) raised under the same environmental conditions, were compared. One-d-old, mixedsex WM (200), and 200 broilers (Ross, CB) each were randomly assigned to floor pens (20 chickens per pen). The production stages (I, II, and III) were selected based on similar live weight. The crude fat contents of WM thigh meat were lower than those of CB. WM thigh meat contained higher stearic and arachidonic acid contents but lower palmitoleic and oleic acid contents compared to those of CB. The thigh meat color CIE $L^*$- and CIE $b^*$-values of WM were lower, but inosine-5'-monophosphate content was higher in WM than CB in whole production stages. WM thigh meat showed higher collagen content, hardness, springiness, gumminess, and chewiness than CB. In sensory evaluation, odor, taste, and overall acceptance were higher while color was lower in WM. Based on these results, it can be concluded that even if commercial broilers are raised under the same environmental conditions as WM, the unique quality attributes of WM thigh meat are distinctively unique.

Low-fat sausages with or without 10% hydrated rice flour were made from duck, chicken and pork and their physical and sensory properties were compared. Results showed that moisture content did not differ significantly among the sausage batters. However, crude protein, crude fat and total ash content were significantly lower in the group with added rice flour compared with the no flour group. Crude protein and crude fat were the highest in pork sausages without rice flour (p<0.05). Adding 10% rice flour reduced total expressible fluid in all meat type sausages. Cooking loss was also decreased when 10% rice flour was used in making sausages from chicken and pork. However, no changes in cooking loss were found in duck meat by adding rice flour. Again, the highest cooking loss was in pork sausages without rice flour and lowest in chicken sausages with 10% rice flour. The pH of the meat from different animal species differs significantly, although no significant difference was found within meat types with or without rice flour. Lightness ($L^*$) increased, while redness ($a^*$) decreased with adding rice flour in all meat type sausages. Results showed that hardness was significantly reduced when 10% rice flour was added to pork, chicken and duck meat (p<0.05). This may be due to increased water retention of rice flour after cooking. Sensory evaluation indicated that the overall acceptability of pork and chicken sausages with or without rice flour was the same, but duck sausages without rice flour had the highest off-flavor score among the sausages. Addition of rice flour increased the overall acceptability of duck sausage to that of pork and chicken sausages.

This study investigated the quality properties of smoked breast meats produced by fresh and frozen-thawed duck meat. Each thirty breast meats from fresh and frozen-thawed duck carcass was used for this study. The yield of smoked breast meat was measured right after curing and smoking of raw duck breast meat. And, the number of total aerobic bacteria, color, texture, and sensory property of vacuum-packaged smoked breast meats were evaluated during storage at $4^{\circ}C$ for 28 days. No significant difference was found in yield between smoked breast meats produced by fresh and thawed duck meats (p>0.05). The number of total aerobic bacteria and color of smoked breast meat produced by thawed duck meat were not significantly different compared with those by fresh one throughout storage period (p>0.05). The all texture properties were not significantly different between smoked breast meats produced by fresh and thawed duck meats by 14 days of storage (p>0.05). However, on day 21 and 28, the hardness and gumminess of smoked breast meat produced by fresh duck meat were significantly higher than those by thawed one (p<0.05). In sensorial property, smoked breast meat produced by thawed duck meat received significantly high scores in color, juiciness, and tenderness on days 0, 14, and 28 and in flavor and overall acceptance on days 0 and 14 compared with those by fresh one (p<0.05). Therefore, we concluded that the use of thawed duck meat for producing smoked duck meat product may be not worse than the use of fresh duck meat in quality of smoked duck meat product. In addition, the use of thawed duck meat may be better in sensorial quality of smoked duck meat product than that of fresh one.

The meats of tuna Thunnus albacares and swordfish Xiphias gladius are ideal for fish patty production, offering high nutrition and other health benefits. Although red fish meat, including tuna, is added for cost-effectiveness, swordfish white meat is also used, as its aroma resembles that of market-sold beef patties. Here, we assessed the different blending ratios of tuna red meat and swordfish white meat (60:40, 40:60, 20:80, and 0:100) to find the optimal combination for fish patty production. Regarding color, the heated fish patties exhibited increased redness (a*) and yellowness (b*) compared with those of non-heated ones, with similar brightness (L*). The heated patties also scored higher concerning hardness, springiness, gumminess, and chewiness. A higher proportion of swordfish white meat resulted in a softer texture, particularly in patties with a ratio of 40% red meat to 60% white meat. Considering the results of the texture comparison analysis, it is recommended that the texture be improved by increasing the physical property "softness." Sensory evaluations revealed that the addition of white meat led to increased scores in terms of smell, beef taste, texture, and elasticity. These results suggest that swordfish white meat, with improved overall quality, is a suitable raw material for fish patties. Accordingly, the recommended ratio of 20% tuna red meat to 80% swordfish white meat is optimal for fish patty production.

In order to study the tenderizing effect of the proteolytic enzyme, ficin, from fig fruit (Ficus carica L), the enzyme was purified from fig latex by precipitation and chromatography. The ficin separated from Bongraesi showed single band on SDS-PAGE. However, the ficin from Masui showed tow bands. The specific activity of ficin purified from Bongraesi species was 2.8 unit/mg protein and that from Masui species was 6.5 unit / mg protein. The amounts of ficin purified from 50 mL of crude latex of Bongraesi and Masui were 1,760 mg and 657 mg, respectively. the water holding capacity of beef decreased to the large extent, when sugar Bongraesi latex and Masui latex were added. The hardness of beef showed decreasing tendency with the time, however, after 60 min, it decreased and thereafter increased a little after 120 min. the hardness of beef decreased sharply with addition of the latex of Bongraesi and Masui. The Masui has more tenderizing effect than the Bongraesi. When meat was mixed with tenderizing agent(ficin) and not heated, the change of color showed significant difference (p＜0.01). when meat was mixed with tenderizing agent(ficin) and heated, the toughness showed significant difference (p＜0.01) and the softness showed significant difference (p＜0.001).

Low-fat sausages were prepared with various meats to investigate the effect of the addition of oatmeal at 10% as a fat substitute. The sausages were made with beef, pork and chicken after trimming the visible fat, and the physical and sensory properties of the sausages were evaluated. Beef sausage had the lowest cooking yield and the highest hardness, while chicken sausage showed the opposite properties. The addition of oatmeal resulted in sausage products with less cooking loss and softer texture for all types of meat sausages. Such changes were more pronounced for beef low-fat sausage than for the other types of sausages. The results of moisture absorption suggested that the difference in cooking yield and hardness among sausage products was due to the water-retention properties of different meats and the substitute in response to heat treatment. Sensory evaluation indicated that the greatest overall acceptability of the sausage products were obtained from 10% oatmeal-added pork sausage and that the addition of oatmeal led to better acceptability for all types meat sausages.

어육연제품은 최근 그 생산량이 급증하고 있으나 AF-2 등 식품방부제의 사용이 전면 금지됨에 따라 재래식 방법으로 만든 어묵은 유통상 상당한 어려움을 겪고 있다. 이를 결정하기 위한 방안의 하나로 영양적 및 관능적인 품질의 저하를 최소화하되 저장 수명이 길면서 상온유통이 가능한 제품생산을 위한 고온열처리조건을 밝히고자 하였다. 즉 열처리시간은 $F_o$-값 6을 기준으로 하고 레토르트파우치 튀김어묵의 크기와 열처리온도를 달리 하였을 때의 품질을 검토하였다. 젤리강도와 경도는 열처리온도가 높을수록 컸으며 보수력과 강성은 차이가 없었다. 젤리강도, 경도, 명도 및 in vitro 단백질소화율은 전 제품에서 모두 직경이 12mm인 것을 $124^{\circ}C$에서 ?처리한 것이 가장 좋았다. 그러나 관능검사 결과는 $124^{\circ}C$에서 열처리 16mm의 것이 12mm의 그것보다 더 높은 점수를 나타내었다. 저장 40일까지 전 제품의 젤리강도는 증가하였다. 그러나 70일 저장하였을 때는 직경이 12mm인 것만 증가하고 23mm 이상의 것들은 대체로 크게 감소하였다. 저장중 직경이 23mm 이상의 제품은 약간씩 그리고 직경이 16mm 이상인 것은 크게 그 경도가 증가하였다. 전 제품에서 16mm 이상인 것은 크게 그 경도가 증가하였다. 전 제품에서 보수력, 강성 그리고 색조는 전 저장기간을 통하여 큰 변화가 없었다. 이상의 결과로 레토르트파우치 튀김어묵을 제조할 때 직경이 16mm 혹은 그 이상의 것은 고온단시간열처리로 품질저하를 최소화할 수 있다는 결론을 얻었다.

The effects of reducing fat levels from 30% to 20% and salt concentrations from 1.5% to 1.0% by partially substituting incorporated phosphate and sea mustard were investigated based on physicochemical properties of reduced-fat / low-NaCl meat emulsion systems. Cooking loss and emulsion stability, hardness, springiness, and cohesiveness for reduced-fat / low-NaCl meat emulsion systems with 20% pork back fat and 1.2% sodium chloride samples with incorporation of phosphate and sea mustard were similar to the control with 30% pork back fat and 1.5% sodium chloride. Results showed that reduced-fat / low-NaCl meat emulsion system samples containing phosphate and sea mustard had higher apparent viscosity. The results of this study show that the incorporation of phosphate and sea mustard in the formulation will successfully reduce fat and salt in the final meat products.
