This study investigated the physicochemical and sensory characteristics of fish paste containing red snow crab Chionoecetes japonicus leg-meat powder (RMP) in 0, 3, 6, 9, and 12% concentrations. The moisture contents of fish paste with RMP ranged from 56.7 to 60.2% and the pH ranged from 7.0 to 7.7. The L values decreased as the RMP concentration increased, and a and b increased. The folding test for all of the fish paste samples scored AA, which indicates good flexibility. The hardness, springiness, gumminess, and cohesiveness increased with the RMP concentration. In the sensory evaluation, the fish paste prepared with 6% RMP was the most preferred. These results suggest that RMP can be added to fish paste to achieve high quality.

The effects of salt concentration and heating conditions on the thermal gelation properties of surimi produced from mechanically deboned chicken meat (MDCM) were investigated. Chicken surimi was manufactured by washing (MDCM: 0.5% NaCl=1:4), standing, straining and centrifuging. The fat, water-soluble protein and heme pigment in the MDCM were removed by increasing washing cycles. The compressive force of the chicken surimi increased as the concentration of salt was increased from 0% to 5%. Total gel strength of the surimi measured by texture profile analysis showed a maximum in the range 3-5% NaCl. Microstructural analysis showed that the unfolding network structure of the surimi gel began to appear at NaCl concentrations>2%. The optimum heating condition for gelation was $90^{\circ}C$ for 40 min as this resulted in maximum values for measures of gel strength including compressive force, hardness, fracturability, adhesiveness, springiness, gumminess, chewiness and resilience. Chicken surimi gel formed by cooking at a heating rate of $1^{\circ}C/min$ to $90^{\circ}C$ showed better a texture than gels produced at $1.85^{\circ}C/min$. Our result show that a lower rate of heating improves chicken surimi gelation.

The quality characteristics and storage stability of chicken breast meat (CBM) was investigated following the injection of whey protein (WP) as a curing ingredient. The moisture content of CBM decreased with increasing concentration of WP. The highest concentration of WP (7%) resulted in the lowest moisture and fat content and the highest protein content of CBM. Injection of WP elevated the pH and water holding capacity (WHC) of CBM. The cooking loss of CBM was significantly decreased with WP injections of 3% and higher. All WP injections increased the $L^*$ of the CBM but decreased the $a^*$ and $b^*$. WP injection increased the springiness, cohesiveness, and chewiness and decreased the hardness of the CBM. WP injection increased 2-thiobarbituric acid reactive substances (TBARS) after 3 and 7 days of storage. The volatile basic nitrogen (VBN) content of the CBM increased with increased concentrations of WP. The total microbial count (TMC) of CBM injected with WP was higher initially and after 3 days of storage. Our results showed WP injection improved the WHC of CBM but decreased the storage stability by increasing TBARS, VBN and TMC.

The effects of replacing pork meat with yellow mealworms on the physicochemical properties and sensory characteristics of frankfurters were investigated in this study. The control (50% pork ham), T1 (45% pork ham + 5% yellow mealworm), T2 (40% pork ham + 10% yellow mealworm), T3 (35% pork ham + 15% yellow mealworm), T4 (30% pork ham + 20% yellow mealworm), T5 (25% pork ham + 25% yellow mealworm), and T6 (20% pork ham + 30% yellow mealworm) were prepared, replacing lean pork meat with yellow mealworm. The moisture content, lightness, sarcoplasmic protein solubility, hardness, gumminess, chewiness, and apparent viscosity of frankfurters with yellow mealworm were lower than those of the control (p<0.05), whereas the content of protein and ash, pH, and yellowness of frankfurters with yellow mealworm were higher than those of the control (p<0.05). The fat content of frankfurters in T1 (p<0.05) was the highest, and the fat content of treatments decreased with increasing yellow mealworm concentrations (p<0.05). Frankfurters with increasing yellow mealworm concentrations had lower color, flavor, off-flavor, and juiciness scores. The overall acceptability was not significantly different in the control, T1, and T2 (p>0.05). Thus, the results of this study showed that replacing lean pork meat with up to 10% yellow mealworm successfully maintained the quality of frankfurters at a level similar to that of the regular control frankfurters.

This study was conducted to develop chicken meat patties by incorporating pomegranate peel and bagasse powders and their extracts. Patties were developed by incorporating pomegranate peel powder (PPP, 2 g), pomegranate aril bagasse powder (PABP, 4 g), pomegranate peel powder aqueous extract (PPAE, 6 g) and pomegranate aril bagasse powder aqueous extract (PABAE, 9 g) individually per 100 g of minced meat. Both types of powders and extracts treated patties had significantly higher total phenolic content than control and butylated hydroxytoluene (BHT) treated patties. Both types of powder (PPP and PABP) treated patties had significantly higher water holding capacity, ash, crude fibre content, and hardness values, and significantly lower moisture content and lightness values in comparison to control patties. Emulsion stability and cooking yield of PABP treated patties were significantly higher than control. Addition of extracts and BHT did not influence the physico-chemical properties and proximate composition of chicken patties. Both types of powders and extracts provided better protection to chicken meat patties against oxidative rancidity and microbial proliferation in comparison to control and BHT treated patties during refrigerated storage. It is concluded that pomegranate fruit byproducts in the form of peel powder, aril bagasse powder and their extracts can be successfully utilised in development of healthier chicken meat patties and these byproducts can also be effectively used as a replacement of synthetic antioxidants such as BHT.

The effects of adding egg white, bovine plasma protein(bpp), gelatin and gluten on the rheological properties of squid meat paste product(squid meat kamaboko) were examined by the measurements of jelly strength, texture, moisture content, water holding capacity(WHC) and folding test. The optimum added levels for jelly strength of squid meat kamaboko were 4% of egg white, 5% of bovine plasma protein, 3% of gelatin and 4% for gluten. However, it is no increase that at added additives of over this concentrations were. Bovine plasma protein gave the highest jelly strength among the all additives at every concentration. Folding tests value of the optimum added levels were all B value. In this case moisture content and water holding capacity were 72.06∼73.78% and 88.53∼91.11% in jumbo squid, also flying squid were 71.91∼72.89% and 90.21∼93.25%, respectively. The additives were increased the jelly strength, hardness and water holding capacity(WHC), and these effects were eliminated by adjusting the water-content to the value of the control sample without additives.

Effect of fish oil and mugwort pelleted on meat quality in 40 pigs was investigated. The pigs were randomly assigned to one of the four dietary treatments : 1) Control (commercial feed 2) T1 (commercial feed supplemented with 1% fish oil and 1% mugwort pelleted 3) T2 (commercial feed supplemented with 1% fish oil and 3% mugwort pelleted) 4) T3 (commercial feed supplemented with 1% fish oil and 5% mugwort pelleted). The weight gain was not significantly difference between control and treatment groups(p<0.05). In proximate composition, crude fat of pork from treatment groups were decreased by addition level increased than that of control (p<0.05) but moisture crude protein and crude ash was no significantly difference. The total cholesterol, HDL-C and triglyceride of treatment groups was higher than that of control. LDL-C of control was higher than that of treatment groups. The pH, WHC (water holding capacity) and shear force of treatment groups were higher than control group. Especially pH, WHC and shear force was higher in T3 than other treatment groups (p<0.05). The meat color of treatment groups showed whiter than that of control group owing to higher $L^*$ value. The hardness and flavor of sensory evaluation were improved by treatments, especially in T2 and T3 (p<0.05).

The effect of high temperature aging on the meat tenderness improvement was studied, and also the effect of salt, pyrophosphate and succinic anhydride on binding characteristics of restructed beef were compared. At high temperature aging, shear force value decreased and myofibrillar fragmentation index increased as the aging progressed. From the electronic microscopic observation, the morphological change of myofibril appeared much faster when the meat was aged at high temperature. Added salt increased TBA values and rupture strength while reducing cooking loss. Increase in pyrophosphate decreased rooking loss and Increased rupture strength and TBA value. When salt and pyrophosphate were combined, the effects were somewhat additive. Added succinic anhydride increased cooking loss and hardness and decreased color rating, acceptability rating and adhesiveness, but cohessiveness was not significantly different from control group containing salt and pyrophosphate. The results suggest that high temperature aging have greater improving effect of meat tenderness of Korean native male cattle compared to low temperature aging and addition of succinic ahydride in combination with salt and pyrophosphate reduce binding ability of restructured beef.

Effects of freezing period and chilling process after thawing on the physicochemical properties and palatability of hind shank meat from Korean native beef were investigated. There were no significant differences in the Hunter's color, volatile basic nitrogen (VBN) or collagen amount of hind shank meat upon freezing with vacuum packing at $-20^{\circ}C$ for 9 months. In addition, while pH, thiobarbituric acid (TBA) value, hardness, drip and boiling loss of hind shank meat increased and palatability decreased, there significant difference were observed only after 9 months. Softness, water holding capacity, L-glutamic acid, oleic acid, and polyunsaturated fatty acid contents increased upon chilling for 4 days after thawing, and there was a significant increase in palatability. The values of VBN and TBA increased markedly upon 6 days of chilling after thawing, and there was a significant decrease in palatability.

The experiment was conducted to study the effect of sea urchin shell powder (SUSD) on the sensory evaluation, meat color, fatty acid and amino acid contents of chicken meat. One hundred sixty broilers were fed diets for five weeks containing 0, 1, 3 and $5\%$ of sea urchin shell powder. The shear forces of the treatment groups were higher than the control uoup and the water holding capacity (WHC) was higher in the control group (P<0.05). The heating loss and pH were not significantly different between control and treatment groups (P<0.05). The hardness, juiciness and flavor evaluated by sensory evaluation were improved by treatments, especially in T2 (P<0.05). The meat color of the treatments group showed redder and darker than that of the control group owing to lower L$\ast$ and higher a$\ast$ value. Among fatty acids, oleic acid contents of the treatment groups were higher than that of the control group. The treatment groups showed a significantly higher total amino acid content (P<0.05) compared to the control group. The results of this experiment indicated that dietary SUSP tended to improve the sensory evaluation.
