We developed a type of sausage made of chicken breast and liquid egg whites for consumers interested in weight management. To determine the quality of the product, its chemical characteristics, fatty acid composition, free amino acid contents, and nucleotides contents were evaluated during 4 weeks of storage. Sensory evaluation was conducted by both general consumers and body-builders. The sausage was proposed as a fat-free product as fat content was 0.12% based on the Korean Indication Standard of Animal Origin Food. Protein content was 13.42% and calorie value was 61.50 kcal/100 g of the sausage. In sensory evaluation, the mixture of chicken breast and egg whites stuffed into the same casing had an adverse effect on taste, color, texture and overall acceptance while the product that contained egg white stuffed separately into the outer casing enclosing the chicken breast (double layer) improved these attributes. The developed double-layer sausage can last for at least 4 weeks of storage without quality deterioration of flavor-related compounds, such as fatty acids and nucleotides.

The relevant main constituents of rosemary are compound of a vast number of polyphenolics, including carnosic acid, carnosol, rosmarinic acid, and ursolic acid. Recently, phenolic compounds of plant origin have attracted considerable attention due to their beneficial functional and nutritional effects including antioxidant and antibacterial activity. This study was carried out to investigated effect of carnosic acid on pH, thiobarbituric acid reactive substance (TBARS), volatile basic nitrogen (VBN), 2,2-diphenyl-1-picryhydrazyl (DPPH) radical scavenging activity, and total bacteria counts in white sausage during the storage at room temperature. Addition of carnosic acid was decreased of pH, TBARS, VBN, and enhanced antioxidant and antibacterial activity in white sausage. These activities increased with increasing concentrations of carnosic acid. Furthermore, the potent antibacterial activities of carnosic acid against pathogenic bacteria (Escherichia coli KCCM 11234 and Salmonella enteritidis KCCM 12021) were measured. Carnosic acid showed noticeable inhibitory effects on E. coli and S. enteritidis. In conclusion, carnosic acid might be used as a natural preservative in white sausage.

The Hen's egg is widely used in many processed foods as an ingredient and is one of the most prevalent food allergens in children. To detect egg proteins in processed foods, we developed a competitive indirect enzyme-linked immunosorbent assay (ciELISA) using an anti-ovomucoid (OM) antibody, which was produced by immunization of rabbits with OM, the most heat-stable component of the egg proteins. The detection limit of this quantitative assay system was 30 ng/mL. Cross-reactivity of the anti-OM antibody toward OM, ovalbumin, skim milk, casein, whey protein isolate, and isolated soy protein was 100, 0.4, 0.2, 0.04, 0, and 0%, respectively. In the spike test of egg white powder in milk replacer, commercial sausage, and in-house sausage, the assay recoveries ($mean{\pm}SD$) were $129{\pm}13.7%$, $73.9{\pm}12.5%$, and $65.5{\pm}13.6%$, respectively. When egg white in a commercial crab meat analog and sausage was determined by ciELISA, the assay recovery was found to be 108% and 127%, respectively. The combined results of this study indicate that this novel ciELISA for OM detection could be applied for the quantification of hen's egg proteins in processed foods.

This study was performed to examine the levels of biogenic amines (BAs) in foods of animal origin such as egg, ham, sausage, milk, cheese and yoghurt distributed on Korean domestic markets, and to compare the results with those of western countries. Egg yolk had more BAs than egg white. BAs detected in ham samples were the highest level in barbecued tender loin ham. Sausage samples had less BAs than ham samples. However, the delicatessen sausages had significantly higher levels of histamine than the other sausage samples (p<0.001). Cadaverine, spermidine and spermine were detected in market milks and their concentrations were very low compared with other samples. In Cheddar cheese, tyramine (44.46${\pm}$0.83 ${\mu}$g/g) was the major BA. The major BA of stirred yoghurt samples was histamine. These results suggest that BAs of the foods of animal origin distributed on Korean domestic markets were not much different from those of western countries and would not cause any harmful effect to consumers.

To elucidate the effect of egg white lysozyme from Ogol fowl on the preservation of milks, fishcurd and sausage, changes of pH, volatile base nitrogen content and viable cell count were investigated during the storage periods at $20^{\circ}C$, $30^{\circ}C$ and $37^{\circ}C$ after the addition of lysozyme in each foods. Volatile base nitrogen count of raw milk as marker of spoilage was lowest(63 mg%) in 0.05% lysozyme addition lot which was stored at $20^{\circ}C$ for 2 days, and its preservation effect by lysozyme at $30^{\circ}C$ was enhanced with addition of glycine(0.1%). Preservation effect by lysozyme in commercial milk at $37^{\circ}C$ and in fishcurd at $5^{\circ}C$ and $20^{\circ}C$ were also good, and when sausage was stored at $5^{\circ}C$ after treatment of lysozyme instead of sorbic acid, its preservation effect was acceptable.

Objective: The objective of this study was to evaluate the effects of ageing time of lamb loins prior to freezing on technological characteristics and oxidation stability of coarse ground lamb loin sausage using in a model system. Methods: Lamb loins (M. longissimus lumborum, n = 25) were aged at $-1.5^{\circ}C$ for 0, 1, 2, 3, and 8 wk and then frozen for the remaining days (a total of 30 wk). The aged/frozen/thawed lamb loins were ground, and model sausages were formulated with 75% aged/frozen/thawed lamb loin, 25% water, 1.5% sodium chloride (NaCl) and 0.3% sodium tripolyphosphate. The pH and thaw/purge loss of aged/frozen/thawed lamb loins were evaluated, and protein functionality (protein solubility and emulsifying capacity), water-holding capacity and textural properties of model sausages were determined. Cooked model sausages were vacuum-packaged in a plastic bag and displayed under continuous fluorescent natural white light ($3^{\circ}C{\pm}1^{\circ}C$). Colour and lipid oxidation of the cooked model sausages were evaluated on 0 and 21 d of display storage. Results: Ageing prior to freezing had no impact on pH and purge/thaw loss of lamb loins and the colour of cooked sausages (p>0.05) made from the loins. Lamb loins aged for at least 3 wk prior to freezing numerically improved total and myofibrillar protein solubilities (p>0.05) and emulsion activity index (p = 0.009) of meat batter, but decreased cooking loss (p = 0.003) and lipid oxidation (p<0.05) of model sausages. Conclusion: This study suggests that post-mortem ageing of raw meat prior to freezing could improve water-holding capacity and lipid oxidative stability of sausage made from the meat.

We gamma-irradiated to natural casings from lamb and pork to improve sanitary quality and microbiological shelf stability of sausage stuffed in animal intestine-induced natural casing from lamb and pork. The microbial changes of irradiated casings and the microbial growth of the sausages with gamma-irradiated natural casings were observed. Population of total aerobic bacteria was decreased by gamma irradiation, dependent upon the irradiation dose. The number of microflora in lamb and pork casings was reduced by about 5.5 log cycle at 5 kGy. Population of total aerobic bacteria of sausages stuffed in non-irradiated lamb and pork casing was about 3.6 log CFU/g after just manufacture and was about 7 log after 10 day storage. However, population of total aerobic bacteria of sausages with 3 kGy-irradiated and 5 kGy-irradiated casings was 2.48 and 0.32 log in lamb, and 2.78 and 0.60 log in pork, respectively. Gamma irradiation to animal intestine- induced natural casings was effective and thus, can be used for enhancing shelf life of final products due to reduction of the number of contaminated microflora.

The standard cooking method of Soondae, a famous traditional sausage type food in Korea, was proposed and the applicability of porcine plasma and egg white as the substitute of the porcine blood was investigated for the improvement of off-flavor, rancidity, and acceptability of Soondae. Sensory evaluation suggested Soondae prepared with 15% porcine blood most preferred. The cooking yields, water absorption capacity and hardness of plasma and egg white added Soondae were decreased compared with those of original porcine blood Soondae. The overall results of sensory evaluation suggested the possibility of using porcine plasma or egg white as a substitute for the porcine blood in Soondae.

the objective of this study was to develop the Korean style fermented sausage by addition of Korean native spices(Mugwort Artemisaia asiatica ;pine needles pinus thunbergii ; Japanese pepper Zanth-oxylum prperitum ; Arrowroot pueraria hirsuta) instead of foreign-original spices(white pepper corian-der)pH of all sausages was lowered rapidly during ripening. pH reductio of sausages with foreign spices was mere rapid than that with Korean native spices except for the sausages with all mixtured Korean native spices. Aw was not affected by differentiated spices. The "a" value among Hunter Color Value of sausages that produced with mixed Korean native spices was higher than sausages with foreign spices Lactic acid bacteria rapidly increased and reached to 108cfu/g after 2 days of ripening. Korean native spices used to this work did not inhibit the inhibit of lactic acid bacteria in fermented sausages but enterobacteria did not detected after 10 days of fermentation in the sausages with mixed Korean native spices.
