Nitrite is an essential additive for cured meat product. Plasma is ionized gas and reactive nitrogen species in plasma can be infused into meat batter and subsequently generate nitrites by reaction with water molecules after plasma treatment. However, the increase of nitrite in meat batter is limited with direct treatment of atmospheric pressure cold plasma because of the increase of meat batter temperature. Therefore, this study investigated the influence of indirect treatment of atmospheric pressure cold plasma on the physicochemical properties of meat batter. Meat batter was indirectly treated with plasma at 1.5 kW for 60 min. The pH of meat batter decreased while the temperature increased with plasma treatment time. The total aerobic bacterial count of meat batter was not affected by plasma treatment. The nitrite content of meat batter was increased to 377.68 mg/kg after 60 min of plasma treatment. The residual nitrite content of cooked meat batter also increased with plasma treatment time. The CIE $a^*$-value of cooked meat batter increased. As plasma treatment time increased, lipid oxidation tended to increase and protein oxidation significantly increased. According to these results, the indirect treatment of atmospheric pressure cold plasma can be used as a new curing method for replacing synthetic nitrite salts.

Effects of NaCl concentration (0, 1, 2, and 3%) on the physico-chemical characteristics of dark, firm, dry (DFD) and normal meat batter were examined. Before heating, pH values of DFD and normal meat batter decreased up to 0.23 (DFD) and 0.2 (normal) units, which after heating increased up to $0.16{\sim}0.28$ and $0.17{\sim}0.23$ units, as NaCl concentration increased from 0 to 3%. Cooking loss and diameter reduction of DFD meat batter were lower than those of nomal meat batter and decreased. whereas protein solubilities and emulsion stabilities of DFD and normal meat increased, with increasing NaCl concentration. Protein solubility and emulsion stability of DFD meat were higher than those of nomal meat (p<0.05). Viscosity and hardness of DFD meat batter were higher than those of normal meat batter and increased as NaCl concentration increased from 0 to 3%.

This study was conducted to investigate the physicochemical properties of meat batters prepared with fresh pork meat, back fat, water, and salt and formulated with three different amounts (5%, 10%, and 15%) of silkworm pupae (Bombyx mori) powder and transglutaminase (TG). Meat batters formulated with silkworm pupae powder showed significantly higher contents of protein and ash than control batter. Addition of silkworm pupae to batter also showed significantly lower cooking loss than the control. Moreover, meat batter containing 15% silkworm pupae showed no significant difference in redness value compared to the control. In addition, pH, viscosity, hardness, gumminess, and chewiness were improved after the addition of silkworm pupae. Furthermore, meat batter formulated with TG and silkworm pupae showed improved hardness, gumminess, chewiness and viscosity compared to control batter. Addition of 1% TG with 15% silkworm pupae to meat batter resulted in significantly higher pH, textures, and viscosity. Our data suggest that both silkworm pupae and TG can be added to meat batter to improve its physicochemical properties. Therefore, combination of silkworm pupae and TG could be a new nutritional and functional source for meat products.

The interaction of plasma with liquid generates nitrogen species including nitrite (NO⁻₂). Therefore, the color developing capacity of plasma-treated water (PTW) as a nitrite source for meat curing was investigated in this study. PTW, which is generated by surface dielectric barrier discharge in air, and the increase of plasma treatment time resulted in increase of nitrite concentration in PTW. The PTW used in this study contains 46 ppm nitrite after plasma treatment for 30 min. To evaluate the effect of PTW on the cured meat color, meat batters were prepared under three different conditions (control, non-cured meat batter; PTW, meat batter cured with PTW; Sodium nitrite, meat batter cured with sodium nitrite). The meat batters were vacuum-packaged and cooked in a water-bath at 80℃ for 30 min. The typical color of cured meat developed in cooked meat batter treated with sodium nitrite or PTW. The lightness (L*) and yellowness (b*) values were similar in all conditions, whereas, the redness (a*) values of cooked meat batter with PTW and sodium nitrite (p<0.05) were significantly higher than the control. These data indicate that PTW can be used as a nitrite source in the curing process of meat without addition of other nitrite sources.

본 실험은 ISP, CSP의 대체제로서의 wheat fiber첨가가 meat batter의 품질에 미치는 영향을 조사하였다. Meat batter에서 control은 처리구와 비교하여 가열감량, 보수력, 유화안정성, 물성, 점도에서 유의적인 차이가 있었다. Meat batter에 wheat fiber를 첨가하였을 경우, ISP, CSP를 첨가한 처리구와 비교하여 pH, 보수력, 육색, 유화안정성, springiness, cohesiveness는 유의적인 차이가 나타나지 않았으며, 가열감량과 점도, hardness는 다른 첨가제와 비교하여 wheat fiber가 유의적으로 낮은 결과를 나타내었다. 이상의 결과 ISP, CSP의 대체제로 wheat fiber를 첨가한다면 meat batter의 품질에 영향을 주지 않으며, 경제적인 측면에서 제품의 단가를 절감할 수 있을 것으로 생각된다.

The purpose of this study was to investigate the effect of wheat fiber as a replacement for isolated soy protein (ISP) or concentrated soy protein (CSP) on the quality characteristics of meat batter. Meat batter formulations were prepared with 2% levels of ISP, CSP, or wheat fiber. The pH values of each formulation were not significantly different (p>0.05). The L-values of meat batter containing wheat fiber, ISP, or CSP were higher than the control, however the a- and b-values were lower than the control (p<0.05). Relative to the control meat batter, the water holding capacity, viscosity, hardness, gumminess, and chewiness of meat batter containing ISP, CSP, or wheat fiber was significantly higher than the control (p<0.05). All supplemented meat batters had significantly lower cooking loss and emulsification stability than the control (p<0.05), with no significant difference among the supplemented meat batters. The results of this study show that the use of wheat fiber as an ISP or CSP replacer does not affect the overall quality of meat batter.

Nitrite is an essential additive for the manufacture of cured meat products. This study was conducted to investigate the curing effect of the plasma treated juice of red Perilla in meat batter. The nitrite content in the juice of red Perilla was increased by the indirect treatment of atmospheric pressure plasma, and the lyophilized powder of red Perilla juice contained 9,133 ppm of nitrite. A meat batter without a nitrite source was prepared as a negative control (NC), and the meat batters cured with sodium nitrite (PC), celery powder (CP), and the lyophilized powder of red Perilla juice treated with atmospheric pressure plasma (PTP) at 70 ppm level of nitrite were prepared. The PTP showed the highest pH and the lowest cooking loss among the treatments. There were no significant differences in the nitrosyl-hemochrome content in the cooked meat batters of the PC, CP and PTC. However, the PTP had a lower CIE $a^*$-value compared to the PC and CP. The malondialdehyde content in the cooked meat batters was significantly lower in the CP and PTP than in the NC while there was no significant difference between the NC and PC. Based on the results of this study, the plasma treated juice of red Perilla can be used as a new natural nitrite source for cured meat products.

This study was conducted to identify the quality and functional properties of meat and meat batter among commercial broilers and two different ages of spent layers. Breast and whole leg meat samples were prepared from the broilers and spent layers to compare meat quality traits: Commercial broiler (Arbor Acre; 6-week-old) and two different ages of spent layers (Hy-Line; 70 and 95-week-old). Three types of meat batters containing breast meat as 50% of total ingredients were also prepared to analyze processing qualities. The broiler showed the highest water holding capacity (p<0.05) and the lowest cooking loss value (p<0.05) in both meat and meat batter samples. The breast and leg meat of the 95-week-old layers showed the highest shear force value (p<0.05), and also showed the highest shear force and hardness values in the meat batter. Although the oldest layer meat showed tougher textural traits than the 70-week-old layers, no significant differences were found for cooking loss and water loss values in both the meat and meat batter samples. Besides, panelists gave equivalent scores within different ages and parts of the cooked layer meats in the sensory evaluation. Similar ratios of polyunsaturated fatty acids to saturated fatty acids, and omega-6 to omega-3 fatty acids were obtained from both the 70-week-old layer and 95-week-old layer meats. In conclusion, the 95-week-old spent layers, especially for breast meat, had equivalent potential as raw materials for processed meat products compared to the 70-week-old layers.

The effect of applying edible coating and addition of antioxidants (butylated hydroxyanisole (BHA) plus butylated hydroxytoluene (BHT) in a 1:1 ratio) on pork patties were investigated prior to achieve desired physico-chemical, microbiological and sensory qualities. For this, five treatments were conducted as (i) control (neither coated nor antioxidants treated); (ii) coated without antioxidants treated; (iii) coated and antioxidants added in the batter mix only (100 ppm); (iv) coated and antioxidants added in meat mix (100 ppm) only; and (v) coated and antioxidants added both in the batter mix (50 ppm) and the meat mix (50 ppm). Addition of antioxidants both in the batter mix and the meat mix significantly (p<0.05) reduced the microbial loads and thiobarbituric acid (TBA) values. The TBA values significantly (p<0.05) increased up to day 14 and then progressively increased with the advancement of each interval of storage days up to 28 days. Total plate count significantly (p<0.05) increased with the increase in storage days.Coliform and Staphylococcus aureus were absent throughout the storage days in all samples. Staphylococcus aureus however, were present in the control group at day 14 and in enrobed (coated) patties (without antioxidants treated) at 28th day. Addition of antioxidants to batter mix and meat mix did not substantially enhance bacteriostatic activity. Application of coatings and antioxidants retarded the loss of firmness, flavor, changes in appearance and color, and also other sensory attributes. Control patties were better with respect to microbial quality and TBA values but had poorer sensory quality than coated patties.

The efficiency of three concentrations (0.05, 0.1, and 0.2%) of Ganghwayakssuk (Artemisia princeps Pamp.) extract on the susceptibility of raw chicken nugget batter to lipid oxidation was investigated after 0, 3, 7, and 10 d of refrigerated storage at $4^{\circ}C$. The pH and yellowness values of all treatments were higher than those of the control (p<0.05). Additionally, the lightness and redness values of all treatments were lower than those of the control and as the amount of Ganghwayakssuk ethanolic extracts increased. At the end of the storage period (10 d), the peroxide values (POV), conjugated dienes (CD), and thiobarbituric acid reactive substances (TBARS) values were lower than those of the control. The results show that Ganghwayakssuk prevents lipid oxidation in raw chicken nugget batter.
