  • This study was conducted in order to evaluate the effect of gamma irradiation on improvement of the quality and safety of meat products. Emulsion type bologna sausages were manufactured with 3 kGy gamma irradiated ground beef. Beef patties were also manufactured with the addition of antioxidants (200 ppm, BHA, ascorbyl palmitate, ${\alpha}-tocopherol,\;or\;{\beta}-carotene$) following gamma irradiation of 1.5 or 3 kGy. Bologna sausages could be successfully manufactured with 3 kGy gamma irradiated ground beef and lower salt content(NaCl of 1.0 or 1.2% and phosphate of 0.2 or 0.3%) without any deteriorative results when compared with the products manufactured with regular salt content(NaCl of 1.5~2.0% and phos phate of 0.4~0.6%). No colony formations of aerobic microorganisms were observed in the sausage with NaCl of 1.2% and phosphate of 0.2 or 0.3% up to 30 days storage at $10^{\circ}C$. No significant differences appeared in the TBA values among all the sausages during storage for 30 days. No colonies of aerobic microorganisms were observed in the 3 kGy irradiated patty. Lipid oxidation of the beef patties was inhibited by the addition of an antioxidant.

  • This study was conducted to investigate the effects of herbs (dill weed, fennel seed and rosemary) on color stability and lipid oxidation of ground pork patties during storage at $2^{\circ}C$ and $-20^{\circ}C$. Lipid oxidation was determined by the thiobarbituric acid reactive substances (TBARS) method. Fennel seed was identified as being the most effective ingredient in terms of meat redness (Hunter a-values) during storage at $2^{\circ}C$ (p<0.05). Patties treated with rosemary had lower Hunter a-values than control, and dill weed was the least beneficial in influencing meat redness, having significantly lower a-values than control patties. During frozen storage at $-20^{\circ}C$, no significant differences in a-values were observed between the control patties and those treated with fennel seed. Patties treated with rosemary had lower a-values than control and patties with dill weed had negative a-values throughout storage. The cooking process increased Hunter L-values and decreased a-values in all patty samples. TBARS values increased during storage. Rosemary displayed excellent antioxidative activity as evidenced by the completely inhibition of TBARS formation of cooked pork patties. Dill weed and fennel seed also exerted an intermediate but significant antioxidant effect during storage (p<0.05).

  • The objective of this study was to determine the effect of reheating methods on the color characteristics of precooked pork patties with various NaCl and phosphate levels. NaCl/phosphate levels for each formulation were as follows; N1 (1% NaCl), N1+P (1% NaCl+0.3% phosphate), N2 (2% NaCl), and N2+P (2% NaCl+0.3% phosphate). The reheating methods used were by electric grill and microwave oven. The surface color of the patties reheated by microwave showed more brown and less-intense red, and the phosphate-treated patties reheated by microwave were more reddish and less brownish. With increased amounts of added NaCl and phosphate, the internal color of patties was more reddish, and the phosphate-treated patties reheated by microwave had more brown than those reheated by electric grill. Among all of the treatments, there were no significant differences in surface color, internal color, and overall appearance. Thus, the color changes in reheated patties were influenced by reheating methods and phosphate.

Physico-chemical Properties and Utilization of Sarcoplasmic Proteins for the Determination of End-point Cooking Temperatures of Ground Pork Hams Containing Salt and Fat (식염 및 지방을 함유한 분쇄돈육의 이화학적 성상 및 최종가열온도 측정을 위한 근장단백질의 이용)

  • Processed meals, such as a ground meat and hamburger patty, are required to ensure that no pathogens remain in the final products. However, there was no rapid method available to verify that the recommended end-point cooking temperature(EPT) was reached. Thus, the objective of this study was to rapidly determine EPT of ground pork hams using sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SOS-PAGE), based on the disappearance of sarcoplasmic proteins after cooking. Fresh pork hams were added two levels of salt(0, 2%) and fat(15, 25%) combinations, and stored in refrigerator overnight, and cooked to internal cooking temperatures of $64^{\circ}C$ to $74^{\circ}C$ with $2^{\circ}C$ increments. Cooked pork hams were measured cooking loss(CL, %), protein solubility(PS) and SOS-PAGE. CL(%) was reduced with the addition of 2% salt, as compared to the control, regardless of fat contents. It was also increased with increasing eooking temperature. Protein solubility was affected by the cooking temperature, resulting in reduced PS up to $64^{\circ}C$(P < 0.05), but remained constant higher than $68^{\circ}C$. In SOS-PAGE analysis, protein bands with the molecular weights of 36 and 66 kDa were affected by the addition of salt and fat combinations. regardless of treatments. These protein fractions were decreased gradually with increased cooking temperatures up to $68^{\circ}C$ ${\sim}$ $70^{\circ}C$ and might be good indicators for the determination of EPT in ground pork hams.
