  • The objective of this study was to investigate the effect of red ginseng extracted with water extract (WE) and 50% ethanol extract (EE) from white ginseng on cooked meat patties during storage. Different concentrations of extracts were examined (0.25%, 0.5%, and 1.%, respectively, dry base w/w). A significantly higher water holding capacity (WHC) was observed in samples supplemented with ${\geq}$ 0.5% WE (p < 0.01); however, EE had no significant effect on the WHC of meat patties. Samples supplemented with ${\geq}$ 0.5% WE or EE showed a significantly higher redness ($a^*$-value) compared to the control (p < 0.01). The total plate counts (TPC) and 2-thiobarbituric acid-reactive substances (TBARS) of all treated samples were lower than those of the control. However, there were no significant differences in volatile basic nitrogen (VBN) values and sensory evaluation scores between the samples. These results suggest that red ginseng extract improves color and inhibits lipid oxidation and bacterial population at doses > 0.25%, prolonging the shelf-life of meat products and acting as a natural colorant.

  • Pork patties were made containing hot air dried sweet persimmon powder (T1: 3%, T2: 6%) and freezer dried sweet persimmon powder (T3: 3%, T4: 6%). The control (C: no addition) and each treatment were stored for 40 days at $-18^{\circ}C$. The pH value decreased (p<0.05) in all products over 30 days of storage but slightly increased thereafter. There was no significant difference in WHC between the control and treatment groups. Cooking loss and meat color (CIE L, a, b) increased significantly (p<0.05) as storage increased. The cooking loss of meat patties containing sweet persimmon powder were significantly (p<0.05) higher than the control. The L value of the control increased significantly (p<0.05) relative to the treatment groups, however the a and b values were slightly higher in meat patties containing sweet persimmon powder. In all products, the reduction ratio of diameter increased (p<0.05) with storage time. With regard to microorganisms, all samples were in good condition, containing below 4.20 log CFU/g based on total plate counts through 40 days, though total plate counts and coliform plate counts of the control were lower (p<0.05) than T3 and T4. The VBN values of T4 was significantly higher than those of other products at 15, 30, and 40 days of storage. The TBARS values of meat patties containing sweet persimmon powder were significantly (p<0.05) higher than those of the conlIol. Sensory panels determined that meat patties containing sweet persimmon powder had a higher (p>0.05) preference score for overall acceptability.

  • This study investigated the effects of saltwort powder on the antioxidant activity and quality characteristics of patties added with saltwort powder. Patties were prepared with different amounts (0, 1, 2, and 3%) of saltwort powder. The total phenolic content, DPPH free radical scavenging activity, and pH of patties increased with increasing saltwort powder content (P<0.05). In particular, the moisture content and cooking loss of the group added with 2% saltwort powder were the highest and lowest, respectively (P<0.05). As the content of saltwort powder increased, $L^*$ and $a^*$ values decreased while $b^*$ value increased. Texture analysis showed that the hardness, chewiness, and gumminess of the control group were lower than those of the treated group (P<0.05). Consumer acceptability showed that 1% and 2% saltwort powder groups scored higher in terms of overall preference, appearance, color, taste, and texture compared to the other groups. Characteristic intensity rating of saltwort patties showed that as more saltwort powder was added, saltwort taste intensified; however, the increase did not affect juiciness, off flavor, or salty taste of the patties. Judging from the results, it was concluded that the addition of saltwort powder to patties in processing can enhance the preference, quality, and antioxidant activities of the patties, which elevates the value of patties.

  • This study was performed to determine the antioxidant activity of the oven-dried paprika powder as affected by the color differences of paprika and to evaluate physicochemical characteristics and antioxidant activity of pork patties with various levels of paprika powders. The total phenolic contents of the paprika were not affected by color and solvent (p>0.05). The methanol extracted paprika powder showed higher DPPH radical scavenging activity than water extracted counterpart, and no differences were observed at concentration of 0.5% as compared to the reference (ascorbic acid) (p>0.05). In all treatments, the iron chelating ability increased with increasing concentrations. At a concentration of 1.0%, methanol extracts of orange paprika (MOP) and water extracts of red paprika (WRP) were not different from the reference, (ethylendiaminetetraacetic acid, EDTA). The paprika color and extraction solvent didn't affect reducing power of paprika powder at each concentration (p>0.05). Pork patties with red paprika powder were higher redness values than those with orange ones, regardless of addition level. The addition of red paprika increased the yellowness, and patties with 1.0% orange paprika powder showed the highest value. TBARS values were decreased with increasing paprika powder, especially, patties with 1.0% paprika powder were lower TBARS than those with 0.5% paprika powder, resulting in similar to those with ascorbic acid (p>0.05). Although the microbial counts increased with storage time, paprika powders did not inhibit microorganisms during storage. In conclusion, paprika powders could be used as a natural antioxidant in meat products, regardless of paprika color.
