To obtain basic data for processing semi-dried salmon meat product, the results that were measured the textural properties of salmon meat during salting, sugaring and drying process followed. Drying time and temperature were longer, the moisture amount of salmon meat were reduced. Hardness of salmon meat was direct proportion to shear stress, but hardness was inverse proportion to cohesiveness during drying process. After sugaring and salting salmon meat, drying time was longer, hardness and shear stress of salmon meat were increased. The sensory evaluation of the textures of sugaring salmon meat dried for 3 hrs showed slightly good. In the changes of texture of salmon meat during steaming hardness and shear stress of salmon meat dried for 4 hrs were higher than that dried for 10 hrs. And steaming time was longer, hardness of salmon meat dried for 4 hrs was decreased and cohesiveness was not changed.

This study was conducted to investigate the effect of the lipid and collagen content and drip volume on the hardness of fish meat. Red sea bream (cultured and wild) and flounder (cultured, cultured with obosan and wild) were used for this study. Textural differences between cultured and wild meats were determined by the measurements of hardness, lipid and collagen content, and drip volume. Lipid content of the dorsal muscle was higher especially in cultured red sea bream (3.32%) than in wild one. Cultured and wild flounder contained lower content of lipid than red sea bream. The content of collagen was higher in cultured flounder fed with obosan (8.37 mg/g muscle) and wild flounder (8.02 mg/g muscle) than others. Drip volume was the highest in cultured flounder fed with obosan (8.67%). The hardness of raw meat was correlated with the contents of lipid (r= -0.7063) and collagen (r= 0.8307), significantly. Cultured fish contained more lipid and less collagen than wild one. So, the hardness of these fish meats was lower than wild one. However, cultured flounder fed with obosan showed no difference in hardness compared with wild one. In the cooked meat, there was no relationship between the hardness of fish meat and the contents of lipid and collagen. But, the drip volume was significantly related with the hardness (r= 0.6870). From these results, the factors contributing the textural difference between wild and cultured fish meat would be the lipid and collagen contents, and two ways to improve the texture of cultured fish meat could be suggested. One is to lower the lipid content by feed control, and the other is to raise the collagen content by inducing more fish movement.

This paper aims to compare and evaluate the quality of beef jerky made with Korean beef meat, Korean beef cattle and imported beef meat from Australia and New Zealand through sensory evaluation, measurement of hardness, thickness and contents of the moisture and crude lipid, and microscopic texture observation (SEM). According to the sensory evaluation, beef jerky made with Korean beef meat recorded the highest score in overall acceptability; New Zealand beef meat, the lowest. The preference of beef jerky made with Korean beef meat was shown in the appearance, smell, and texture, and especially in the taste. Whereas Korean beef jerky scored highest in color, glaze and palatability, New Zealand beef meat showed the lowest score. Korean beef meat showed the lowest in hardness, but New Zealand beef meat showed the highest as shown in the result of technical evaluation through rheometer. The evaluation through colormeter concluded that New Zealand beef meat had the highest scores in L and a values, but that Korean beef meat showed the lowest score. When it comes to the color difference compared with Korean beef meat, New Zealand beef meat showed the biggest difference. Although the moisture contents of jerky made with different beef meat showed little difference, the content of the crude lipid of jerky made with Korean beef meat and Australian beef meat was lower than that of Korean beef cattle and New Zealand beef meat. When the beef jerky is dry, fat contained in the beef meat is dissolved, which causes the glaze on the outside. Scanning electron micrographs showed that Korean and Australian beef jerky had larger gaps than Korean beef cattle and New Zealand beef jerky. It was concluded that this affected the hardness of beef jerky.

The effect of additional amounts of subsidiary materials on texture of fish meat paste were examined using Instron Universal Testing Machine to obtain fundamental data for steamed Alaska pollack meat paste showing good quality. The hardness revealed the good correlation with jelly strength among the six kinds of parameters of Instron texturometer. Products with higher hardness showed a better quality, but those with hardness higher than 16kg showed decreasing quality with increasing hardness. Predicting the quality of steamed Alaska pollack meat paste with various additional amounts of subsidiary materials as a function of hardness, H, the equation could be deduced as follows: H=11.56+0.54Xcs, H=12.22-0.23Xsp and H=11.65-7.13Xpp. The reasonable equations for predicting the quality of steamed Alaska pollack meat paste with various additional amounts of mixed subsidiary materials could be summarized as follows: H=11.57+0.53Xcs+0.44Xsp, H=11.97-1.83Xpp-0.17Xcs, and H=11.58+0.08Xpp-0.23Xsp.

The purpose of this study was to examine the effects of freezing and thawing methods on the quality of pork meat. The freezing methods for pork meat were the cryogenic freezing with liquid nitrogen gas, fast freezing at $-70^{\circ}C$ and normal freezing at $-20^{\circ}C$. The thawing methods were tested on low temperature thawing at refrigerative temperature($4^{\circ}C$), room temperature($20^{\circ}C$), high temperature($60^{\circ}C$) and using microwave. The quality of pork meat frozen by cryogenic methods was better than those of fast and normal freezing methods. The cooking hardness of pork meat frozen by cryogenic method showed the highest value as 1,898 g. In case of fast freezing, the hardness of pork meat was 1,472 g and that of normal frozen pork meat was 1,541 g. The high cooking hardness value of cryogenic frozen pork meat showed that the cryogenic freezing method made less freeze damage like textural softness. The drip-loss of pork meat thawed at refrigerative temperature($4^{\circ}C$), room temperature($20^{\circ}C$), high temperature($60^{\circ}C$) were shown lower than that of microwave thawing. The cooking hardness of pork meat that was thawed by microwave showed the lowest value among the thawing methods. The cryogenic freezing was the most useful freezing method for preserving quality, decreasing the freeze damage of pork meat. And thawing at refrigerative temperature was the most effective method to prevent quality loss and weight loss by drip-loss.

Quality attributes of reconstructed pork patties with ISP were evaluated. Reconstructed pork patties with 30% meat plus ISP and 50% meat plus had significantly less cooking loss and dimensional changes than control. Sensory evaluation revealed patties with 30 or 50% meat had higher hardness and juiciness than control, patties with ISP, and patties with direct addition of ISP. Objective elasticities of patties with 30 or 50 % meat were high, whereas patties without ISP had higher values of hardness, gumminess, and chewiness. Color of patties with 30 or 50% meat were different from that of control. These result show addition of ISP to meat emulsion for pork patties markedly improved cooking loss, dimensional changes, hardness, and juiciness. When pork patties and cutlets prepared according to meat (30%) formula were frozen, cooking loss was significantly higher in slow-frozen patties, but freezing rate did not affect dimensional changes of patties and cutlets. Slow-frozen patties had higher hardness, but other textural properties were affected by the freezing rate. Quality of pork cutlets was not significantly changed by the freezing rate.

Unique organoleptic characteristics such as rich flavors and chewy texture contribute to the higher popularity of native chicken in many Asian areas, while the commercial broilers are well-accepted due to their fast-growing and higher yields of meat. Sensory attributes of foods are often used to evaluate food eating quality and serve as references during the selection of foods. In this study, a three-phase descriptive sensory study was conducted to evaluate the sensory attributes of commercial broiler (BR) and Taiwan native chicken (TNC) breast meat, and investigate correlations between these sensory attributes and instrumental measurements. The results showed that for the first bite (phase 1), TNC meat had significantly higher moisture release, hardness, springiness, and cohesiveness than BR meat. After chewing for 10 to 12 bites (phase 2), TNC meat presented significantly higher chewdown hardness and meat particle size, whereas BR meat had significantly higher cohesiveness of mass. After swallowing (phase 3), TNC meat had higher chewiness and oily mouthcoat and lower residual loose particles than BR meat. TNC meat also provided more intense chicken flavors. This study clearly demonstrates that descriptive sensory analysis provides more detailed and more objectively information about the sensory attributes of meats from various chicken breeds. Additionally, sensory textural attributes vary between BR and TNC meat, and are highly correlated to the shear force value and collagen content which influence meat eating qualities greatly. The poultry industry and scientists should be able to recognize the sensory characteristics of different chicken meats more clearly. Accordingly, based on the meat's unique sensory and physicochemical characteristics, future work might address how meat from various breeds could best satisfy consumer needs using various cooking methods.

Sea mustard paste was prepared by treating wet and dried sea mustard with 0.1M Na2CO3, which mainly aimed to extract alginate from the cell wall of sea mustard. The pastes were added to beef, chicken and pork to manufacture the meat patties. The effects of adding the paste were investigated in terms of sensory properties, texture(hardness)and weight changes after cooking. The sensory attributes such as taste, color, texture and juiciness were generally enhanced by adding the paste. The hardness of cooked patties was significantly decreased, so the paste provided softer texture. The addition of paste also resulted in decreasing the weight loss of meat patties after cooking.

This study was performed to evaluate the effects of chicken breast meat on the quality of mackerel sausages. The mackerel sausages were manufactured by additions of 5%, 7%, and 10% of chicken breast meat. The lightness of mackerel sausages showed no significant differences between the control and addition groups. The redness increased in a dose-dependent manner, but the yellowness decreased significantly with the addition of 7% chicken breast meat (p<0.05). The whiteness value of mackerel sausage added with 7% chicken breast meat was significantly higher than those of the other groups (p<0.05). In texture analysis, the hardness and adhesiveness of the mackerel sausage added with 5% of chicken breast meat showed no significant differences as compared to the control. However, the mackerel sausages added with 7% and 10% of chicken breast meat showed a dose-dependent decrease. The gel strength of the mackerel sausage added with 5% chicken breast meat was not significantly different from the control, but the addition of 7% and 10% chicken breast meat reduced the gel strength of the mackerel sausage. In sensory evaluation, the mackerel sausages prepared with chicken breast meat have higher scores in smell, taste, texture, hardness, chewiness, and overall preference as compared to the no addition group. Therefore, these results suggest that the optimal condition for improving the properties within mackerel sausages was 5% addition of chicken breast meat.

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.
