  • This study was conducted to investigate the influence of dietary mugwort (0, 1, 2, 4%) and sardline oil(1%) on weight gain, pH, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), and meat color in meat-type chickens. Birds were randomly assigned to the four dietary treatments: control (commercial feed), control plus 1% mugwort and sardine oil (T1), 2% mugwort and 1% sardine oil(T2), or 4% mugwort and 1% sardine oil (T3). Birds were sacrificed and meat samples were taken and stored for either 0, 3, 7 or 10 days at $4^{\circ}C$. Weight gain in T3 was lowest than other treatment groups (P<0.05). pH of dietary mugwort and sardine oil treatments increased significantly compared to that of control during storage periods (P<0.05). VBN and TBARS of all treatment groups were significantly increased as storage period extended (P<0.05). Meat color $(L^*,\;b^*)$ significantly increased during storage periods. $L^*\;and\;b^*$ values were higher in treatment groups than in control (P<0.05). These results indicate that the mugwort and fish oil may improve quality and self-life of meat-type chickens during storage.

  • The interaction of myofibrillar protein with lipid or oxidized lipid was considered to be mostly contributing to the drop of digestibility of fish meat products. The digestibility of myofibrillar protein was $92.11\%$ for flounder and $88.04\%$ for hairtail fish, repectively, and as a rule it decreased as both the amount of lipid and reaction time increased. It also decreased with increase in the amount of added linoleate and oxidized linoleate. However, when the reaction continued for 6 hours or more the digestibility rather increased, which was provably due to the unfolding of protein structure. The hot air dried hairtail fish showed the lowest C-PER values among all dried fish products. The protein quality of flounder, hairtail fish and their dried ones except hot air dried ones measured by C-PER procedure were superior to that of ANRC casein. DC-PER values of all samples were greater than those of C-PER values and the greater discrepancies were noted in hairtail fish (fatty fish) products which possessed the lower in vitro protein digestibilities. Predicted diegstibilities, which were calculated using amino acid profiles, of all samples except raw ones were overestimated in comparison with in vitro protein digestibilities. From the observations so far, formation of complex of lipids and protein was thought to be the most important factor in lowering protein digestibility of the dried fish meat products.

  • Objective: This study was to investigate the nutrient ileal digestibility of dried mealworm (Tenebrio molitor) larvae and compare with those of three animal protein by-products in growing pigs. Methods: A total of 12 crossbred ($[Landrace{\times}Yorkshire]{\times}Duroc$) growing pigs with average body weights of $24.12{\pm}0.68kg$ were surgically equipped with simple T-cannulas after being deprived of feed for 24 h according to published surgical procedures. These pigs had a recovery period of two weeks. A total of 12 pigs were assigned to individual metabolic crates and allotted to one of four treatments with 3 replicates in a fully randomized design. Dietary treatments included the following: i) Fish meal, corn-vegetable by-product basal diet+9.95% fish meal; ii) Meat meal, corn-vegetable by-product basal diet+9.95% meat meal; iii) Poultry meal, cornvegetable by-product basal diet+9.95% poultry meal; iv) Tenebrio molitor, corn-vegetable by-product basal diet+9.95% dried Tenebrio molitor larvae. Results: Results showed that the apparent ileal digestibility (AID) of Lys was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal diet. Pigs fed Tenebrio molitor diet showed increased (p<0.05) AID of His and Arg compared to pigs fed Fish meal or Meat meal diet. The AID of Cys was increased (p<0.05) in pigs fed poultry meal and Tenebrio molitor diets compared to that in pigs fish meal diet. Pigs fed meat meal, poultry meal, and Tenebrio molitor diets showed higher (p<0.05) standardized ileal digestibility (SID) of total energy compared to pigs fed fish meal diet. The SID of Arg was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal or meat meal diet. Furthermore, pigs fed poultry meal or Tenebrio molitor diets showed increased (p<0.05) SID of Cys compared to pigs fed fish meal diet. Conclusion: In conclusion, providing pigs with diets that contained Tenebrio molitor larvae meal improved AID and SID of nutrients as well as essential and non-essential amino acids. The digestibility of dried mealworm larvae protein and its utilization in vivo are also good. Therefore, dried mealworm larvae protein can be used as protein source at 10% level in growing pigs.

  • This study was conducted to determine the effect of dietary soy isoflavone (ISF, 0 and 20 mg/kg) on performance, meat quality and antioxidative property in male broilers. Six replicates of 45 birds (42 d old) were used for each treatment. The birds were fed soybean meal-free diets containing 3% oxidized fish oil (acid value, 6.76 mg potassium hydroxide/g; and peroxide value, 6.18 meq/kg) for 3 wk. The results showed that average daily gain, feed intake, feed conversion and carcass traits were not affected by soy ISF. Compared with the control group, breast muscle color redness value and water holding capacity were increased (p<0.05) by ISF supplementation. The activity of plasma catalase was increased by supplementing with 20 mg ISF/kg diet. In breast muscle, Broilers fed 20 mg ISF/kg had decreased production of malondialdehyde and lactic acid. The ISF supplementation elevated total antioxidative capacity and activities of total superoxide dismutase and glutathione peroxidase. The results indicated that dietary ISF could increase redness and water holding capacity of meat, and antioxidative property of meat in male broilers fed oxidized fish oil diet.

  • This study examined the effect of pretreated sandfish Arctoscopus japonicus meat as a surimi complex for preparing sandfish flavored fish paste. To prepare the sandfish-flavored paste, fine chopped sandfish meat including backbone was added in a ratio of 0 to 50 wt.% to thawed Alaska pollock Theragra chalcogramma surimi to make a mixed surimi gel. To prepare the sandfish-flavored paste, the mixed surimi was ground with salt using a silent cutter, mixed with starch and stabilizers 0.2% transglutaminase and gluconolactone 0.3%, stuffed in a rectangular container, left for 3 h at $25^{\circ}C$, cooked in hot water for 30 min at $90^{\circ}C$, and finally chilled for 20 min at $4^{\circ}C$. The effects of the pretreatment of sandfish meat were investigated by analyzing the quality of the paste produced. The proximate composition of FP (fish paste containing 40% steam-cooked sandfish meat and 0.3% gluconolactone) was moisture 76.1%, crude protein 12.0%, crude fat 3.8%, carbohydrate 6.1%, and ash 2.0%. The major minerals in FP were Na (23.77 mg/L), Mg (1.46 mg/L), Zn (1.04 mg/L), and Fe (0.41 mg/L), and the major free amino acids were taurine, anserine, alanine, and glutamic acid. The monounsaturated fatty acid content of FP was 566.22 mg%, and the polyunsaturated fatty acid content was 498.43 mg%. The n-3 fatty acid content was 398.01 mg%, and C20:5n-3 (218.85 mg %) was a major component.

  • The aim of this study is to examine the removal efficiency of pathogen (Escherichia coli O157:H7 and Salmonella typhimurium) on meat and fish products (packing condition: vacuum or not and storage temperature: $4^{\circ}C$ or $-20^{\circ}C$) repeatedly exposed at low-dose gamma irradiation. In case of meat products (beef and chicken), E. coli O157:H7 was not observed at the level of 2 kGy single gamma irradiation and 0.5 kGy repeated gamma irradiation and S. Typhimurium was not observed at the level of 2 kGy single gamma irradiation and 1 kGy repeated gamma irradiation. In case of fish products, E. coli O157:H7 and S. Typhimurium were not detected at the level of 0.5 kGy single and repeated gamma irradiation. These results showed that microorganisms on fish products were more efficiently removed than those of meat products with low-dose gamma irradiation. Generally, each packing condition made no difference. However, the products (fish and meat) stored at $-20^{\circ}C$ needed more higher dose gamma irradiation than products at $4^{\circ}C$.

  • In Previous paper, an experimental equation for prediction of thermal diffusivity of white muscled fish meat paste products was suggested. In this paper, another experimental equation for red muscled fish meat paste products was derived. The thermal diffusivities of products with water contents of 44.74 to $82.83\%$ and lipid contents of 0.35 to $23.38\%$ could be deduced as following equations ; $$\alpha_{80.39^{\circ}C}=0.0759{\cdot}10^{-6}{\cdot}X_w+0.0836{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{100.63^{\circ}C}=0.0820{\cdot}10^{-6}{\cdot}X_w+0.0853{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ $$\alpha_{120.09^{\circ}C}=0.0830{\cdot}10^{-6}{\cdot}X_w+0.09140{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The experimental equation derived from these equations was ; $$\alpha=(0.9795+.8996{\cdot}X_w){\cdot}\alpha_w-0.0709{\cdot}10^{-6}{\cdot}X_w-0.0779{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The errors of the thermal diffusivities of red muscled fish meat paste products predicted with this equation were less than ${\pm}\;0.52\%$ compared with those measured. A new experimental equation for products of white and red muscled fish meat paste could be discribed as follow ; $$\alpha=(1.096+0.5318{\cdot}X_w){\cdot}\alpha_w-0.0057{\cdot}10^{-6}{\cdot}X_w-0.0992{\cdot}10^{-6},\;m^2{\cdot}s^{-1}$$ The errors of the thermal diffusivities predicted with this equation were less than ${\pm}\;0.13\%$ compared with those measured.

  • The fish meat paste products are rapidly growing in its production. However, the recent prohibition of AF-2 gives a lot of difficulties in the marketing of fish meat paste products manufactured ty the conventional procedures. The present study aims to obtain the optimal conditions for retaining tile quality of the fish meat paste products with long shelf-life on the market. The fried fish meat paste was sealed in the retort pouches and sterilized under the conditions which the Fo value designated to 6. The effects of the sterilization temperature and the diameter of the products on the quality factors such as jelly strength, water holding capacity, texture and in vitro protein digestibility were investigated. The jelly strength and hardness increased as the sterilization temperature increased. On the other hand, there were no differences found in water holding capacity and elasticity. Of the samples, product with diameter of 12mm showed the highest values of jelly strength, hardness, L values and in vitro protein digestibility which sterilized at $124^{\circ}C$. However. tile results of the organoleptic tests showed rather score in the products with diameter of 16 mm than 12 mm which were sterilized at $124^{\circ}C $. From the results described above, it was concluded that the fried fish meat paste products with 16 mm or less in a diameter which were sterilized at higher temperature could keep high quality.
