For the effective utilization of dark meat separated as by-product from skip-jack canning, the dark meat concentrate(DPC) was prepared by removal of extractable materials with ethanol from dried dark meat. Dark meat protein hydrolysate(DPH) was prepared by the hydrolysis of DPC with ${\alpha}-chymotrypsin$. ${\alpha}-Chymotrypsin$ hydrolysed DPC to the extend of 79% during 10hr. The solubility over a pH range 1~12 showed similar trend on the both of DPH and DPC. The highest solubility was 81% on the DPH and was 36% on the DPC at pH 3. The lowest solubility was 65% on the DPH and was 22% on the DPC at pH 7. The content of total free amino acid was higher in the DPC than in the DPH, but the content of total essential free amino acid was higher in the DPH. Especially, the contents of taurine in the DPC and DPH were much higher than those of other amino acids. The result of sensory evaluation on the fish sauce analogue showed good taste, color and odor at the supplemented level of 8g DPH per 100ml of raw solution of fish sauce analogue and didn't show signifcaint difference compared with market fish sauce(p<0.05). On the preparation of surimi gel, 2% substitution of DPH for the supplemented starch was the most appropriate level.

Effects of four kinds of phosphate complex on the water holding capacity (W.H.C) and protein solubility of yellow-corvenia (Pseudosciance manchurica) and hair tail (Tichurus lepturus) meat paste were investigated. The formulations of four kinds of phosphate complex employed to this experiment were made by mixing several phosphates such as sodium polyphosphate, sodium pyro-phosphate, sodium acid pyro-phosphate, potassium pyro-phosphate, sodium tetra meta-phosphate, sodium ultra meta-phosphate and sodium hexa meta-phosphate, and monoglyceride at different mixture ratios. Among the four kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium poly-phosphate 50%, sodium pyrophosphate 20%, sodium tetra meta-phosphate 20%, sodium acid pyrophosphate 5% and sodium ultra meta-phosphate 5% was most effective on enhancing the W.H.C and protein solubility of yellow corvenia meat paste, and in case of hair tail meat paste, phosphate C complex which was formulated by mining sodium poly-phosphate 40%, sodium pyro-phosphate 30%, potassium pyro-phosphate 15%, sodium tetra meta-phosphate 10%, and sodium hexa meta-phosphate 5% was more effective than other phosphate complex, and their optimum addition level was 0.4% respectively in weight of fish meat paste. Texture characteristics such as hardness, cohesiveness, and springiness value of Kamaboko (fish meat paste product) were evaluated as best when 0.3% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 45 mimutes at $85^{\circ}C$.

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.

For the effective utilization of the fish resource in coastal regions, an investigation on optimum processing conditions and meat quality textured fish protein concentrate (FPC) was carried out with the fish meat of filefish and sardine. Optimum pH and sodium chloride content of fish meat were 7.5 and 1.0 %, respectively. The most effective soaking conditions were as follows ; soaking time, 30 min ; temperature of ethanol, 5 to $20^{\circ}C$ ; amount of added ethanol, 3 times the weight of the fishmeat paste ; repeated number of soaking in ethanol for filefish and sardine, 2 and 4, respectively. The ethanol remaining is meaty textured FPC could be removed effectively by forced-air drying. Yields of the product to the minced meat weight and the contents of protein lipid in meaty textured from filefish were 21.1, 77.6 and 0.2 % and those from sardine were 24.3, 75.8 and 3.6 %, respectively. Contents of essential amino acids in meaty textured FPC of filefish and sardine were not inferior to those of beef, textured soybean protein and FAO pattern. Beef meat could be substituted with the meaty textured FPC up to 50 % in the processing of typical meat balls and hamburger without any significant loss in its taste, odor and texture.

This study aimed to analyze the leading research materials and research trends related to livestock food in Asia in recent years and propose future research agendas to ultimately contribute to the development of related livestock species. On analyzing more than 200 relevant articles, a high frequency of studies on livestock species and products with large breeding scales and vast markets was observed. Asia possesses the largest pig population and most extensive pork market, followed by that of beef, chicken, and milk; moreover, blood and egg markets have also been studied. Regarding research keywords, "meat quality" and "probiotics" were the most common, followed by "antioxidants", which have been extensively studied in the past, and "cultured meat", which has recently gained traction. The future research agenda for meat products is expected to be dominated by alternative livestock products, such as cultured and plant-derived meats; improved meat product functionality and safety; the environmental impacts of livestock farming; and animal welfare research. The future research agenda for dairy products is anticipated to include animal welfare, dairy production, probiotic-based development of high-quality functional dairy products, the development of alternative dairy products, and the advancement of lactose-free or personalized dairy products. However, determining the extent to which the various research articles' findings have been applied in real-world industry proved challenging, and research related to animal food laws and policies and consumer surveys was lacking. In addition, studies on alternatives for sustainable livestock development could not be identified. Therefore, future research may augment industrial application, and multidisciplinary research related to animal food laws and policies as well as eco-friendly livestock production should be strengthened.

We compared between an automated most-probable-number technique $TEMPO^{(R)}$TVC and traditional plating methods $Petrifilm^{TM}$ for estimating populations of total aerobic bacteria in various livestock products. 257 samples randomly selected in local retail stores and 87 samples inoculated with $E.$ $coli$ ATCC 25922, $Staphylococcus$ $aureus$ ATCC 12868 were tested in this study. The degree of agreement was estimated according to the CCFRA (Campden and Chorleywood Food Research Association Group) Guideline 29 and the agreement indicates the difference of two kinds methods is lower than 1 log base 10($log_{10}$). The samples of hams, jerky products, ground meat products, milks, ice creams, infant formulas, and egg heat formed products were showed above 95% in the agreement of methods. In contrast, proportion of agreement on meat extract products, cheeses and sausages were 93.1%, 92.1%, 89.1%, respectively. One press ham and five sausages containing spice and seasoning, two pork cutlets containing spice and bread crumbs, two meat extract product and two natural cheeses and one processing cheese with a high fat content, and one ice cream containing chocolate of all samples showed the discrepancy. Our result suggest that $TEMPO^{(R)}$TVC system is efficient to analyses total aerobic bacteria to compare manual method in time-consuming and laborious process except livestock products having limit of detection.

To maintain the freshness of produce, because of stand away between produced and consumer, we need refrigeration system that can supply to consumer at cold chain as soon as gathering. General refrigeration system consist of refrigeration chamber or low temperature store. But the vacuum technology can rapidly refrigeration without refrigerator. This precool system possible to get low precooled temperature, suitable for the fishes, the meat, the vegetables, the fruit etc. Especially get advantage that quality maintain through rapid refrigeration of ferment directly generate heat. Vacuum precool system's principle is that water saturated temperature reduce according to pressure is get to vacuum area, so product temperature reduce as water evaporation at product. In vacuum suction, unit, on early experiment period run the rotary type vacuum pump at purpose pressure, then maintain pressure by water-diven ejector. As the results, cabbage took about 60 minutes to reach from $23.2^{\circ}C$ to $4.5^{\circ}C$at 5mgHg abs.

We have investigated the effect of lard fraction extracted with supercritical carbon dioxide (SC-$CO_2$) on the flavor enhancement of maillard reaction product (MRP) based meat flavors. MRP based meat flavors were prepared with low glutamic acid (Glu) hydrolyzed wheat gluten (NaCl concentration: 7.61%(w/v)), ribose, cysteine, garlic juice powder, protease-digested Lentinus edodes powder and lard fractions extracted with SC-$CO_2$. Lard was extracted with SC-$CO_2$ at each of three temperatures (40, 60, and $80^{\circ}C$) and at each of four pressures (30, 40, 50, and 60 MPa). Obtained lard SC-$CO_2$ fractions and MRP based meat flavors with those fractions were analyzed for their total yield, aroma pattern by SMart nose system, and sensorial properties. The extraction yield had no difference as temperature increased from $40^{\circ}C$ to $60^{\circ}C$ and even decreased at $80^{\circ}C$. However, increase in pressure level at $40^{\circ}C$ drastically increased the extraction yield. The aroma patterns of raw lard and lard SC-$CO_2$ fractions with 30 MPa were significantly discriminated from those of SC-$CO_2$ lard fractions extracted with higher pressure by SMart nose system. Aroma pattern of MRP based meat flavors with higher pressure extracted lard fractions also showed significant difference through pattern analysis by the SMart nose system. The MRP based meat flavor with lard SC-$CO_2$ fractions at 50 and 60 MPa were described as less sulfuric, less pungent, and more balanced in roasted meat and sweet attributes from sensory evaluation.
