  • This study was carried out to investigate the antioxidative effect of kimchi on the lipid oxidation of cooked meat in model systems. Four model systems of cooked ground meat(CGM). CGM-water(W), CGM-brine(B) and CGM-kimchi(K) were prepared and their oxidation behaviours were evaluated during the storage at 4$^{\circ}C$ for 5 weeks. Thiobarbituric acid values and peroxide values of the systems of CGM, CGM-B and CGM-W increased significantly with the storage time, however, those values of CGM-K were hardly changed during the time of 5 weeks storage. Antioxidative effect of CGM-K increased with the addition level of kimchi in system. And also in the model systems which were prepared with cooked ground meat and kimchi whose fermentation period is different, the antioxidative effect of well ripened and properly fermented kimchi was higher than that of unripened kimchi during the lipid oxidation process of model systems. These results suggested that kimchi especially the properly femented kimchi in the systems plays an important roles as an antioxidative activity on the lipid oxidation of cooked ground meat.

  • This study was carried out to investigate the antioxidative effect of different kinds of kimchi on the lipid oxidation of cooked meat in model systems. Model systems of cooked ground meat(CGM), CGM-Chinese cabbage kimchi(CK), CGM-radish kimchi(RK), and CGM-mustard leaf kimchi(MLK) were prepared and their oxidation were evaluated during the storage at 4$^{\circ}C$ for 5 weeks. Thiobarbituric acid(TBA) values of CGM significantly increased with the storage at 4$^{\circ}C$ for 5 weeks. Thiobarbituric acid(TBA) values of CGM significantly increased with the storage time, however, TBA value of CGM-CK, CGM-RK, and CGM-MLK lowered and that of CGM-MLK was lowest. Antioxidative effect of CGM-MLK increased with the addition levels of kimchi in the system. And also in the model systems which were prepared with CGM and MLK in different fermentation periods, the antioxidative effect was highest in the properly fermented-kimchi.

  • The objective of this study was to determine the effects of short-term presalting on pink color and pigment characteristics in ground chicken breasts after cooking. Four salt levels (0%, 1%, 2%, and 3%) were presalted and stored for 0 and 3 d prior to cooking. Cooking yield was increased as salt level was increased. However, no significant differences in pH values or oxidation reduction potential (ORP) of cooked chicken breasts were observed. Cooked products with more than 2% of salt level had less redder (lower CIE $a^*$ value) on day 3 than on those on day 0. As salt level was increased to 2%, myoglobin was denatured greatly. Myoglobin denaturation was leveled off when samples had 3% of salt. With increasing salt levels, residual nitrite contents were increased while nitrosyl hemochrome contents were decreased. These results demonstrate that salt addition to a level of more than 2% to ground meat may reduce the redness of cooked products and that presalting storage longer than 3 d should be employed to develop a natural pink color of ground chicken products when less than 1% salt is added to ground chicken meat.

  • 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.

  • Purpose: This study aimed to investigate the effect of grape skin on the physicochemical properties and sensory score of ground pork meat. Methods: Four types of ground pork were evaluated: T0 without grape skin, T1 with 0.3% grape skin, T2 with 0.7% grape skin, and T3 with 1.0% grape skin. Results: There was no significant group wise difference in VBN content, L-value, b-value, chemical composition of raw and cooked meat, cooking yield, water holding capacity, moisture retention, fat retention, hardness, springiness, cohesiveness, gumminess, chewiness, taste, texture, juiciness, or palatability. Total polyphenol content was highest in T3, and DPPH radical scavenging activity was highest in T2 and T3 (p<0.001). The pH was highest in T0, and was lowest in T3 (p<0.001). The a-value of T2 and T3 were significantly higher than that of T0 (p<0.05). Flavor was highest in T2 among samples (p<0.01). Conclusion: The study results suggest that grape skin may be a useful ingredient in ground pork meat in terms of antioxidant potential, color and flavor.

  • The purpose of this experiment was to investigate the antioxidant effect of nitrite on total, neutral, and polar lipids and fatty acid composition in laboratory-cooked ground pork. Muscle samples (Biceps femoris) were analyzed using Iatroscan, gas chromatography, phosphorus content, and TBARS value. The total and neutral lipid contents of muscle were higher in nitrite-untreated meat (0 ppm) than in nitrite-treated meat (100 ppm) but the reverse was observed for polar lipid contents. The results for neutral lipids showed a similar trend when compared with total lipids. Polyunsaturated fatty acids contents of total, neutral and polar lipid in 100 ppm treated meat were higher than that of 0 ppm. The phosphorus content was higher in 100 ppm meat than in 0 ppm but the reverse was observed for TBARS value. These results showed that the addition of 100 ppm nitrite to ground pork resulted in a remarkable antioxidant effect during refrigeration storage.

  • This study evaluated the effects of adding levels of rice bran fiber on the chemical compositions, cooking characteristics and sensory properties of ground pork meat products. Meat products were produced with products containing 0% (control), 1%, 2%, 3%, 4%, and 5% and rice bran fiber. The control had the highest protein and fat contents, cooking loss, reduction in diameter, CIE L value and CIE a value of uncooked product, and CIE L value of cooked product. The meat product containing rice bran fiber had the higher ash, pH, and CIE b value than the controls. The addition of 5% rice bran fiber resulted in the lowest cooking loss and L value of cooked meat products. Meat product with 2% rice bran had the highest water content, water holding capacity, hardness, color, tenderness, juiciness values. There was a significant difference among the ground meat products with respect to sensory properties, and meat products containing 1% and 2% rice bran had higher overall acceptability than the other meat products.

  • Turkey thigh meats with skin were ground twice through a 3-mm plate and patties were prepared. Patties were cooked using 5 different methods(oven cooking, pan frying, oil deep frying, boiling, and microwaving) to an internal temperature of 85${\sim}90^{\circ}C$ and packaged in either oxygen permeable PVC zipperbags or oxygen impermeable PVDC bags. The samples were analyzed for thiobarbituric acid reactive substances(TBARS) and cholesterol oxidation products(COPs) after storage at $4^{\circ}C$. The TBARS of cooked meat increased during the storage regardless of cooking methods, vacuum packaged thigh meat produced less TBARS and COPs than the aerobically packaged samples. At the beginning of storage, aerobically packaged meat cooked by boiling method produced higher TBARS than that of others. However, the TBARS of microwaved meat with vacuum packaging increased rapidly after 3 days of storage at $4^{\circ}C$. The amount of total COPs in cooked thigh meat increased linearly with storage time. The level of total COPs in aerobically packaged cooked meat was higher than the vacuum-packaged meat. Microwave produced higher level of total COPs in meat than other cooking methods during storage.

  • Four model systems of ground cooked meat (GCM), GCM-water (W), GCM-brine (B) and GCM-soybean sauce (S) were prepared and stored at $6^{\circ}C$ for 5 weeks. The oxidative behavior of lipids in the systems and the antioxidative effects of soybean sauce on the lipid oxidation were studied during the period of storage.Tiobarbituric acid values and peroxide values of the systems of GCM, GCM-B and GCM-W were increased significantly with the storage time, however, those values of GCM-S were hardly changed during the time of t u·eeks storage. The decreases in the contents of dienoic/polyenoic fatty acids of neutral or phospholipid fraction in GCM-S system were found to be the lowest among the systems during the 5 weeks storage. And also the least development of rancid flavor evaluated by sensory score during storage were observed in GCM-S system. These results are suggested that soybean sauce in the systems plays an important role as an antioxidative material on the lipid oxidation.

  • The effects of pink inhibiting ingredients (PII) to eliminate the pink color defect in cooked turkey breast produced from presalted and stored raw ground turkey in the absence or presence of sodium tripolyphosphate (STP) were examined. Ground turkey breast was mixed with 2% sodium chloride and vacuum packaged. After storage for 6 d, ten PII were individually incorporated without or with added STP (0.5%) as follows: none (control), citric acid (CA; 0.1%, 0.2%, 0.3%), calcium chloride (CC; 0.025%, 0.05%), ethylenediaminetetraacetic acid disodium salt (EDTA; 0.005%, 0.01%), and sodium citrate (SC; 0.5%, 1.0%). Treatments were cooked at a fast or slow cooking rate, cooled, and stored before analysis. All PII tested were capable of lowering inherent pink color compared to the control (No STP: CIE a* pooled day reduction of 23.0%, 5.2%, 12.6%, and 12.6% for CA, CC, EDTA, and SC, respectively; STP: reduction of 21.5%, 17.4%, 6.0%, and 18.2% for CA, CC, EDTA, and SC, respectively). For samples without STP, fast cooking rate resulted in higher CIE a*. However, slow cooking resulted in more red products than fast cooking when samples included STP. Presalting and storage of ground turkey caused the pink discoloration in uncured, cooked turkey (CIE a* 6.24 and 5.12 for without and with STP). This pink discoloration can be decreased by inclusion of CA, CC, EDTA, or SC, but incorporation of CA decreased cooking yield. In particular, the addition of SC may provide some control without negatively impacting the cooking yield.
