Inactivation by UV-C irradiation of Listeria monocytogenes cocktail inoculated on hamburger patties was examined. Hamburger patty samples were inoculated with 6-7 log CFU/mL of L. monocytogenes cocktail, and then exposed to doses of 0, 1, 5, or $10kJ/m^2$ of UV-C light, followed by storage at $4{\pm}1^{\circ}C$ for 7 d. Microbiological evaluation indicated that the populations of L. monocytogenes decreased significantly (p<0.05) as irradiation dose increased. In particular, L. monocytogenes populations decreased by 2.03 log CFU/g after exposure to 10 $kJ/m^2$, compared with control samples. The thiobarbituric acid-reactive substance levels of hamburger patty samples increased during storage, regardless of UV-C irradiation status. These results indicate that UV-C irradiation may be useful in improving the microbial safety of hamburger patties during storage.

The present study was carried out to investigate the effects of soy protein hydrolysates (SPHs) addition on the quality characteristics of pork patties. The SPHs was prepared by subcritical water process (SWP) at 180℃ without holding time and mixed with the pork patty components at varying concentrations (0-3%), and the patties were stored at 4℃ for 14 d. As quality parameters, instrumental color, thiobarbituric acid-reactive substances (TBARS), pH, water holding capacity (WHC) and shear force were measured at the end of storage. Regardless of SPHs concentration, the addition of SPHs significantly manifested low L* and high a* values compared to those of untreated control (p<0.05). For b* value, addition of SPHs in the 0.5-1.5% was unaffected, while >2.0% of SPHs caused significantly lower b* than control (p<0.05). The color changes in pork patties with and without SPHs were also identified in visual appearance where the pork patties containing 0.5-2.0% showed bright red color which was comparable to brownish color of control and patties containing >2.5% SPHs. Lipid oxidation was delayed by the addition of 0.5-1.5% SPHs, while it was accelerated by the addition of 3% SPHs. The pH of patties increased with increasing concentration of SPHs, whereas there were no significant differences in WHC and shear force of patties. Consequently, the results indicated that the addition of 0.5-1.5% SPHs had a potential advantage in suppressing oxidative deterioration of fat-containing meat products during chilled storage.

This study was performed to develop patties with quality characteristics using mealworm powder, followed by assessments of general compositions and the branched-chain amino acid (BCAA) levels of the patties. An analysis of the chromaticity of the patties shows that the lightness and yellowness were decreased, whereas the redness was increased, as the amount of mealworm powder was increased. According to the sensory evaluation, the mealworm patty that contain 20% of mealworm powder (M20) showed an overall high preference level. In terms of the mechanical properties, the hardness, gumminess, and chewiness were significantly increased, whereas the springiness and cohesivensee were decreased, as the amount of mealworm powder was increased. The general composition of the M20 consists of 41.84% (moisture), 8.78% (carbohydrates), 34.42% (crude protein), 13.15% (crude fats), and 1.81% (crude ash). The BCAA contents (leucine, isoleucine, and valine) significantly increased in correspondence with the increases of the as mealworm-powder amount regarding the M20, the BCAA composition consists of the following: leucine (2,906.25 mg/100 g), isoleucine (1,459.09 mg/100 g), and valine (1,813.18 mg/100g). The conclusion of this study suggests that mealworm is a potential food material that could possibly replace meat.

This study was carried out to evaluate the effects of microwave power level on cooking properties of ground pork patties (fat level: 20%). Each patty was cooked from a thawed state to $76.7^{\circ}C$ (center temperature) in a microwave oven with power levels of 40% (360 W), 60% (540 W), 80% (720 W), and 100% (full power, 900 W), respectively. Cooking rate increased with power level, and the non-uniformity also increased with time during cooking. Overheating at the edge of the patties was observed for all power levels, and maximum temperature differences in between the edge position and center position were found in patties cooked at the 900 W power level. Compositional properties, total cooking loss, and drip loss were not affected by power level, although moisture content was lower at the edge than at the center position. As the power level increased, the reduction in patty diameter of cooked patties increased while the reduction in patty thickness decreased. Pork patties cooked at lower power levels (360 W and 540 W) had higher shear force values than those cooked at higher power levels (720 W and 900 W). Few changes were observed in instrumental color values.

In this study, we evaluated the physicochemical and sensorial properties of frozen Hanwoo beef patties prepared from prerigor and post-rigor muscle with soybean sauce or sodium chloride. The pH of the soybean sauce treatments was lower than the sodium chloride treatments (p<0.05); however, the Hanwoo patty prepared from pre-rigor muscle with soybean sauce had a lower cooking loss and smaller diameter than the Hanwoo patty prepared under the same conditions from post-rigor muscle (p<0.05). The addition of the soybean sauce inhibited lipid oxidation due to the antioxidative materials in soybean sauce such as melanoidin. The hardness of patties prepared from pre-rigor treatment was lower relative to those prepared from post-rigor muscle (p<0.05); however, there was no significant difference between springiness, cohesiveness, and chewiness (p>0.05). In the sensory evaluation, patties prepared from pre-rigor muscle with soybean sauce had a significantly high score in all traits (p<0.05); thus, pre-rigor muscle with soybean had the highest overall acceptability. Furthermore, the addition of soybean sauce to pre-rigor muscle produced similar effects as those observed for the addition of sodium chloride in regards to psychochemical properties. Moreover, meat products produced from pre-rigor muscle will have better antioxidative and sensorial properties.

This study aimed to investigate the effect of ethanolic extracts from perilla leaves (PLE) on the quality attributes and polycyclic aromatic hydrocarbons (PAHs) in charcoal-barbecued pork patties. The PLE addition and doneness had no significant effect on the pH of pork patties (p>0.05). Regardless of the concentration, the PLE significantly lower malondialdehyde concentrations and reduced the CIE L^*, CIE a^*, and CIE b^* b^* when compared to control. The addition of 0.2% of PLE did not adversely affect the organoleptic properties of doneness of medium and well-done pork patties. Addition of PLE at 0.4% to medium-cooked pork patties had stronger suppressing effect on the formation of light PAHs compare to control (p<0.05), also adding it to well-done pork patties had the lowest concentration of 4 PAHs and 8 PAHs, and a total of 16 PAHs (p<0.05). Therefore, PLE at 0.4% can be used for suppressing the formation of PAHs and lipid oxidation in well-cooked pork patty.

This study investigated the effects of different charcoals on the occurrence of 16 polycyclic aromatic hydrocarbons (PAHs) in grilled beef steaks and beef patties. Seven different charcoals were used as follows: from oak wood (C1), from orange wood (C2), from Valonia oak wood (C3), from Marabu wood (C4), extruded charcoal from beech wood (C5), from coconut shells (C6), and from hazelnut shells (C7). The grilling times for each charcoal type were 6 min for the beef patties and 7 min for the beef steaks, until the internal temperature reached at least 74℃. The total concentration of 16 PAHs (PAH16) in beef steaks grilled with C1 (35.75 ㎍/kg) and C7 (36.39 ㎍/kg) was higher than that of C3 (23.80 ㎍/kg) and C6 (24.48 ㎍/kg; p<0.05). The highest amounts of PAH16 (216.40 ㎍/kg) were determined in the beef patty samples grilled using C5 (p<0.05). The summation of benzo[a]anthracene, chrysene, benzo[b]fluoranthene and benzo[a]pyrene, referred to as PAH4, was not detected in any of the beef steaks, whereas it was determined in the beef patties grilled with C2 (7.72 ㎍/kg) and C5 (22.95 ㎍/kg; p<0.05). The PAH16 concentrations of the beef patty samples in each charcoal group were significantly higher compared to the beef steaks (p<0.05). To avoid the formation of high PAH levels, the use of extruded charcoal and hazelnut shell charcoal should therefore be avoided when charcoal grilling beef steaks and beef patties, and low-fat meat products should be preferred.
