Chicken meat is a low-fat and high-protein food and consumption of chicken meat has been increasing globally. Various food ingredients are widely added for their specific purpose to processed chicken meat. Nonetheless, concerns about the association between high sodium intake and various diseases as well as negative perceptions of artificial additives are increasing. Therefore, in meat products, it is necessary to reduce the amount of salt and to replace artificial additives with natural ingredients. Our aim was to investigate the quality characteristics of low-salt chicken sausages manufactured with the addition of a winter mushroom powder. Sausages was manufactured with sodium pyrophosphate (0.3%) or winter mushroom powder (0%, 0.5% and 1.0%) to ground chicken breast. As a result of addition of the winter mushroom powder to low-salt chicken sausages, pH of the meat batter increased, and the proportion of jelly and melted fat exuded from sausages was reduced. The texture of sausages was softened and lipid oxidation in sausages was inhibited by the winter mushroom powder. This powder did not negatively affect the color and sensory properties of the sausages. According to the results of this study, the winter mushroom powder can serve as a natural ingredient to improve quality of low-salt chicken sausages.

본 실험에서는 국내에서 널리 사용되어지고 있는 고추의 매운 성분인 캡사이신 및 올레오신을 세절시킨 베이컨 육에 첨가하여 그 저장성효과를 TBA가 및 최근에 개발된 형광 발광 검출기가 부착된 CL-HPLC법을 이용한 과산화물가를 측정하였다. 세절 베이컨 육에 있어서의 TBA가는 캡사이신 0.02% 첨가구, 올레오레신 0.02% 첨가군이 기존에 사용해 온 에리 솔빈산 0.02% 첨가수준보다 항산화 효과가 더 크게 나타났다. CL-HPLC로 검출한 hydroperoxide의 생성은 에리솔빈산 첨가구가 대조군에 비해 효과가 더 크게 나타났으나, 에리솔빈산 0.01% 및 0.02%간의 첨가수준에 따른 차이 보이지 않았다. 캡사이신 0.01% 첨가구는 에리솔빈산 0.02% 첨가효과와 거의 같은 효과를 나타냈으며, 5주째에 있어서는 캡사이신 0.02% 첨가구가 캡사이신 0.01% 첨가구에 비해 항산화효과가 유의하게(p<0.05) 더 높게 나타났다. CL-HPLC를 이용해 세절 베이컨에 대한 과산화물가를 책정한 결과, 올레오레신 0.02% 첨가구는 에리솔빈산 0.02% 및 캡사이신 0.01% 첨가수준의 효과와 거의 비슷한 효과를 나타 냈으며, 올레오레신 0.02% 첨가구는 캡사이신 0.02% 첨가수준과 거의 필적할 정도의 항산화 효과를 나타냈다. CL-HPLC는 항상화 효과 측정에 도입할 수 있는 방법임을 확인하였다.

Purpose: This study investigated consumers' perception of food safety and risk from foodborne illness and consumption pattern of meat and processed meat products in Korea. Methods: A quantitative survey was performed by trained interviewers, surveying 1,500 adults who were randomly selected from six major provinces in Korea. Results: Most of the respondents reported foodborne illness risk related to the consumption of raw meat but not related to heated meat and processed meat products. As respondents perceived the risk of food poisoning from raw meat, the purchase and intake decreased (p<0.001). Most of the respondents considered a low possibility of foodborne illness at home. Seventy-seven percent of the respondents thought that bacteria and virus are the main causes of foodborne illness. Improper storage practice (40.7%) and unsafe food material (29.3%) were the main risk factors contributing to foodborne illness. Perception and practice of food safety was significantly different by the residency area. The most preferred meat, processed meat, and processed ground meat products were pork (58%), ham (31.1%), and pork cutlet (40.4%), respectively. The most preferred cooking method was roasting, regardless of the type of meat, but the second preference for cooking method was significantly affected by the type of meat (p<0.001): stir-fried pork, beef with seasoning, fried-chicken and boiled duck. Frequency of eating out was 0.75/day on weekdays and 0.78/day on weekends at the mainly Korean BBQ restaurant. Conclusion: The results of this study could be used to develop science-based education materials for consumer and the specific guideline of risk management of meat and processed meat products.

The aim of this study was to identify the optimal and superior type of natural calcium for replacing phosphate in cooked ground pork products. To achieve this, 0.5% eggshell calcium (ESC), oyster shell calcium (OSC), marine algae calcium (MAC), or milk calcium (MC) was added to ground pork meat products. The effect of this substitution was studied by comparing the substituted products with products containing 0.3% phosphate blend (control). ESC was considered an ideal phosphate replacer for minimizing the cooking loss, which likely resulted from the increase in the pH of the product. Among the other natural calcium types, OSC treatment did not cause a significant increase in pH, but it lowered the cooking loss. CIE $L^*$ values were higher (p<0.05) in products treated with OSC or MC than the control, and lowest (p<0.05) in the products with ESC. However, products with ESC had higher (p<0.05) CIE $a^*$ and CIE $b^*$ values than the control and products treated with other powders. Compared to the control, products treated with ESC and OSC had similar substitution effects on the textural properties of the products. Therefore, the results of this study suggested that the combined use of ESC and OSC could be a potentially effective method for replacing synthetic phosphate in ground pork products.

Alaska Pollack (Theragramma), Mackerel (Socomber japonicus), yellow corvenia (Pseudosc iance manchurica) were dressed, and then meat was separated from the other parts through a fish meat separator. After dehydration, the meat was ground with a silent cutter, packaged in polyethylene bags, and stored at -15。C for days. Samples were taken at regular intervals throughout the storage period and investigated for changes in puality characteristics such as the amounts of nitrogenous compounds, degree of lipid oxidation, fatty acid composition, and organoleptic factors. The resrlts obtained in this study were as follows; 1. The volatile basic nitrogen[VBN] contents of Alaska pollack, and yellow corvenia meat pastes increased from 14.4, 11.2 and 10.8mg% to 41.6, 38.3 and 40.6mg%, respectively during a 120 day storage period, whereas the trimethylamine oxide nitrogen [TMAO-N] contents decreased from 117.2, 12.8 and 17.2mg% to 40.3, 2.6 and 7.1mg% during the same period. 2. The TBA value of the mackerel meat paste showed a maximum peak after 60 days, and then decreased gradually, whereas the TBAvalues of the alaska pollack and yellow corvenia meat pastes increased steadily during the same period. The acid values of the meat pastes increased during the storage period, while the iodine values decreased. 3. The fatty acid composition of the total lipid of the meat pastes changed considerably during ghe 120 days storage period : saturated fatty acids in the total lipid such as myristic, palmitic, and stearic acid increased, while unsaturated fatty acids such as linoleic, gadoleic, eicosapentaenoic, erucic and docosahexaenoic acid decreased steadily. The initial percentage contents of the unsaturated fatty acids in the total lipid of the Alaska pollack, mackerel, and yellow corvenia meat pastes were 87.2%, 63.9%, and 75.9% respectively. However, the contents decreased to 46.0%, 42.5% and 51.3% after the 120day storage period. 4. The color of the meat pastes changde gradually into dark brown. L values of the meat paste measured with a thistimulus colorimeter decreased steadily during the storage period, while a and b values increased during same period. 5. Judging from the results of organoleptic evaluation on the fish odor, color and overall acceptability, significant difference were found between the odor and color of the mackerel and those of the yellow corvenia meat pastes. Overall acceptability score of yellow corvenia was higher than that of Alaska pollack or mackerel meat pastes.

Among polyunsaturated fatty acids (PURAs) targeted for manipulation in animal tissues (poultry eggs and meat), omega-3 PUFAs(n-3 PUFAs) are discussed in this review. 3 or 5% dietary menhaden oil (MO) supplemented layer diets was reported to increase docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) contents in the egg. MO at 1.5% also increased the deposition of up to 180mg total omega-3 fatty acids / yolk. Utilization of 5% ground flax seed (FS) resulted in similar total omega-3 fatty acid (FA) deposition as 1.5% MO. However, the basic feed formulations used in the Canadian feed industry usually include 10 to 20% FS in the egg laying diets. Recently several studies reported that addition of tocopherols in layer diets increased the tocopherol content more in the egg than any other tissue. One of reports said that 3.5% dietary oil with added tocopherols resulted in increasing tocopherol deposition and FA composition of the egg and other tissues. In the poultry meat, redfish meal (RM;4, 8, 12, 15 and 30% of diet) or redfish oil (RO;2.1 or 4.2% of diet) added to the practical corn-wheat-soybean based diets resulted in an increase in omega-3 FA and docosapentaenoic acid (DPA) contents in broiler meat lipids. Linseed oil (LO;1.0, 2.5, and 5.0% of broiler diet) supplemented in broiler diets also resulted in omega-3 FA and the ratio of omega-6 being significantly higher in poultry meat lipid than MO. Concern about fish flavor resulted in research about fish oil (FO) supplementation in broiler diets. Without the use of antioxidants, no more than 1.5% FO should be fed to broilers due to unacceptable orders from the chicken carcasses. One recent research project found that over 50mg/kg of vitamin E was required for maintaining the stability of unsaturated lipids in the meat. In regards to 'fishy'or 'crabby'taint in the eggs and poultry meat, poultry products remained acceptable when dietary fish oils were stabilized with antioxidants.
