A 60-d feeding trial was conducted to evaluate the effects of diets supplemented with two concentrations (0% and 0.3%) of black raspberry (Rubus coreanus Miquel) fruit by-product (RCFB) on the physicochemical characteristics, oxidative stability, antioxidant capacity, antioxidant enzyme activity, and fatty acid profile of M. longissimus dorsi (LL) porcine muscle from Berkshire finishing pigs meat. Results revealed that regardless of the sex, diets supplemented with 0.3% RCFB reduced (p<0.05) the thiobarbituric acid reactive substances (TBARS) expressed as malonaldehyde (MDA) content effectively. A higher antioxidant capacity [2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity] was found (p<0.05) in response to feeding supplemented with 0.3% RCBF for male or female pigs. Moreover, 0.3% RCFB dietary feed increased (p<0.05) the glutathione peroxidase enzyme activities (GPX1) in blood plasma for male or female pigs. However, no influences were observed (p>0.05) on meat color, WHC, shear force, and fatty acid contents while fed diet supplemented with 0% or 0.3% RCFB for male or female pigs. Overall, this study suggests that a diet supplemented with 0.3% RCFB may beneficially affect owing to better oxidative stability, higher antioxidant capacity, and antioxidant enzyme activity (blood plasma) in pigs which could be a promising natural antioxidant without affecting meat quality traits.

The wienner sausage(natural casing, N), wienner sausage(collagen casing, C), frankfurter sausage(F) and can products[spam(S), luncheon meat(L), jangjorim(J)] were obtained from different Korean meat processing companies and investigated for their salinity, saccharinity, pH, moisture and fat content, meat color and sensory evaluation. In sausage products, the saccharinity percent ranged 4.9∼5.0 in N, 6.6∼8.0 in C, and 5.2∼6.5 in F. The salinity percent of C and F were slightly higher than that of N. The pH values of all sausage product were above 6.0. The L＊ values of N were ranged 49.8∼56.7, which were slightly lower than those of C and R The sausage with high content of crude fat and high L＊value earned the highest score in overall acceptability. In can products, saccharinity percentage was higher in J compared to the S and L. The salinity percentage of S was slightly higher than those of Land J. In meat color, L＊ and a＊ values were not different between S and L, although b＊ value of L was slightly higher than that of S and J. There were not significantly different among can products, however, the product containing low-salt had the highest score in overall acceptability.

The objective of this study was to develop software to predict the kinetic behavior and the probability of foodborne bacterial growth on processed meat products. It is designed for rapid application by non-specialists in predictive microbiology. The software, named Foodborne bacteria Animal product Modeling Equipment (FAME), was developed using Javascript and HTML. FAME consists of a kinetic model and a probabilistic model, and it can be used to predict bacterial growth pattern and probability. In addition, validation and editing of model equation are available in FAME. The data used by the software were constructed with 5,400 frankfurter samples for the kinetic model and 345,600 samples for the probabilistic model using a variety of combinations including atmospheric conditions, temperature, NaCl concentrations and $NaNO_2$ concentrations. Using FAME, users can select the concentrations of NaCl and $NaNO_2$ meat products as well as storage conditions (atmosphere and temperature). The software displays bacterial growth patterns and growth probabilities, which facilitate the determination of optimal safety conditions for meat products. FAME is useful in predicting bacterial kinetic behavior and growth probability, especially for quick application, and is designed for use by non-specialists in predictive microbiology.

Overall quality of six kinds of commercial broiler breast fillets (A~F) retailed in Korea were examined, including proximate composition analysis, shape profile analysis, pH, color, tenderness, cooking loss, descriptive analysis, and consumer testing. A total of 120 breast meat fillets were purchased at a local market. Overall quality of broiler breast meat commercially available in Korea was found to vary significantly, indicating a broad range of product quality in the marketplace. Moisture content of meat ranged from 74.4 to 76.4%, whereas protein, fat, and ash contents were 21.8~25.2, 0.2~0.8, and 1.07~1.16%, respectively. The pH ranged from 6.2 to 6.4, whereas color values ($L^*$, $a^*$, and $b^*$) were 52.2~57.2, -3.5~0.5, and 8.3~13.6, respectively, among all products tested. Approximately 9% variation in cooking loss was detected depending on the products evaluated, whereas shapes (height, width, and length) of meat were also significantly different (15% variation on average). Product F was proven to be the least tender and least liked by consumers, implying that tenderness is a key attribute determining consumer acceptability of broiler breast meat.

We analyzed the HACCP prerequisite of National Veterinary Research and Quarantine Service (NVRQS) and the Food Establishment Inspection Report of US Food and Drug Administration (FDA) to recommend contents and ranges to be complemented and used for preparation of guidelines for more effective application of HACCP prerequisites. We used the HACCP inspection reports implemented by Korea Livestock Products HACCP Accreditation Service from 2007 to 2009, FDA Food Code 2009 Guide 3-B Instructions for Marking the Food Establishment Inspection Report, and Retail Food Establishment Sanitation Requirements of 410 Indiana Administrative Code. Major non-compliance items were open doors and windows, insanitary cleaning of in-use utensil, inadequate record of warehousing, and improper storage, transportation, and labelling. Hot water supply, personal hygiene, and regular product testing were additional week points which should be more strongly controlled by detailed operating guidelines. Also, current prerequisite items were required revision into more precise contents to enhanced the effective evaluation and practical application in meat markets.

The poultry industry in Korean has expanded considerably during the last 15 years. While the number of chicken farms of commercial scale has decreased steadily during the period average farm size increased rapidly. Though the gross national product per capita increased 4.5 folds during ten years period, consumption of chicken meat, like other meats, recorded only 2 folds increase during the period. When domestic market for chicken meat had been open for two years on the basis of minimum market access quotas, importation remained at levels below the quota during the first one and half years. Nevertheless, during the last six months and thereafter, chicken meat importation recorded a steep increase, threatening the domestic industry. Poor productivities of the commercial chicken farms might be the main cause for the inferior competitiveness. For the sustainability of the industry some suggestions were made.

The objective of this study was to address the issues associated with the solubility of the pork meat oligopeptide, while maintaining its original nutritional value and improving its digestibility. The pork meat oligopeptide was used to produce an oral liquid supplement that was contained in a 200 $m{\ell}$ can. The formulation was designed to satisfy 20% of the daily recommended nutrition intake of an adult male aged between 20 and 29. Analysis of the quality characteristics showed that this formulation was highly homogenized as an oral liquid supplement with advanced solubility. In addition, based on the viscosity, pH, color value, turbidity, and brix, the product was shown to advanced processing quality with great solubility; however, there was some concern that the taste would be deteriorated due to the bitter taste of the peptide. Thus, further studies need to be performed before this formulation can be commercialized.

The purpose of this study was to survey the various kinds of cooked beef products focusing on 'Chim' (a steamed beef products) through historical literatures written from 1670 to 1945 in korea. 'Chim' was recorded 25 times in the references and could be classified to 5 groups based on major ingredients such as stomach, intestine, lean meat, tail and ribs. Among the eleven cooked products of 'Chim', 'Kalbi-chim' (a steamed ribs) was recorded most frequently and 'Sundae-chim' (sausage-like product) was the next. Though 'Kalbi-chim' has been used untill present day but 'Sundae-chim' was disappeared in the early 19th centuries. Ribs were most popular ingredient among the major ingredients such as stomach, intestines, lean meat, tail, feet and ribs. Twenty one kinds of subingredients including pheasant meat, blood clot and flour were used for 'Chim'. Decorating ingredients such as roasted sesame power, pine nut and thin-layer fried eggs and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and sesame oil were used for 'Chim'.

Hand deboned and mechanically deboned chicken meat were produced from domestic broilers and spent layers. Meat yield, chemical composition, functional characteristics, storage stability and microbiogical properties were investigated. The results obtained were as follows: 1. 35% of carcass freight was recovered primarily as hand deboned chicken meat (HDM) and 45% secondarily as mechanically deboned chicken meat(MDM), total meat yield reaching 80% of carcass weight. 2. Moisture, protein, fat. ash and calcium content of MDM were 65, 12, 20, 1.7 and $0.2{\sim}0.4%$, respectively MDM was higher than HDM in fat, ash and calcium, but significantly lower in moisture and protein Total pigment content of MDM was 2.5 times higher than that of HDM, such high content being attributed to the increased inclusion of hemoglobin during the mechanical masceration of carcass in the deboning process. 3. The emulsifying capacity (ES) of MDM per g meat was only 70% that of HDM, but when ES was expressed on unit g of protein basis MDM showed even higher ES than HDM primarily due to the higher proportion of salt soluble protein fraction of MDM. 4. Since the TBA value of MDM increased rapidly after 4 weeks of frozen storage at $-20^{\circ}C$, the maximum possible storage period of MDM is estimated to be about 4 weeks. 5. Total microbial counts of MDM was approximately $1.8{\times}10\;cells/g$ showing no great difference from HDM or red meat.
