Objective: This study investigated the effects of dry radish leaf and root on the quality of pork patties during refrigeration storage. Methods: The patties were divided into the following three groups: the control containing 0% dry radish leaf root powder, RL1 containing 0.5% dry radish leaf root powder, and RL2 and RL3 containing 1% and 2% dry radish leaf root powder, respectively. Proximate composition, pH, cooking loss, microbial analysis, lipid oxidation analysis, color, texture profile analysis and sensory test were performed. Results: Moisture, crude protein, and crude ash contents in RL2 and RL3 were significantly higher than those in other groups (p<0.05), whereas crude fat contents in RL2 and RL3 were significantly lower than other groups (p<0.05). Lightness was significantly lower in RL2 and RL3 than in CON (p<0.05). Cooking loss for RL2 and RL3 were significantly lower than those for the other groups (p<0.05). The pH, thiobarbituric acid levels, and total plate counts of RL2 and RL3 were significantly lower than those of CON at days 7 and 14 (p<0.05). Hardness values of RL2 and RL3 were significantly lower than those of CON, whereas chewiness values were higher than those of CON (p<0.05). In addition, the juiciness of RL2 were significantly greater (p<0.05) than those of the other groups. Conclusion: Dried radish leaves and roots improved the proximate composition and quality characteristics of pork patties, providing a basis to produce high-quality patties with extended expiration dates. Thus, dried radish leaves and roots are effective ingredients for health or functional foods.

This study was carried out to investigate the feeding effects of fermented wild grape by-product on pork meat qualities. The samples consisted of the pork not fed fermented wild grape byproduct(FWG-X) and the pork fed fermented wild grape byproduct(FWG-O). The moisture, crude protein, crude fat and crude ash were not significantly different between samples. The cholesterol and TBARS of FWG-O were lower than those of the FWG-X, and the salt soluble protein extractability of FWG-O was higher than that of the FWG-X(p<0.05). The calorie, cooking loss, water holding capacity, pH and volatile basic nitrogen were not significantly different between FWG-X and FWG-O. The meat colors of the a and b value of FWG-O were higher than those of the FWG-X, and in case of the fat color, the a value of FWG-O was higher than that of the FWG-X. The hardness, springiness, cohesiveness, gumminess, chewiness and shear force were not significantly different between FWG-X and FWG-O. The total amino acid contents of FWG-X and FWG-O were 74.35 and 69.59g/100g protein, respectively, The raw meat color of FWG-O was higher than that of the FWG(p<0.01), and the cooked meat color(p<0.05), taste(p<0.001), flavor(p<0.001), juiciness(p<0.01) and palatability(p<0.01) were superior to those of the FWG-X. This study showed that fermented wild grape by-product decreased the cholesterol content and lipid oxidation with enhancing the sensory score.

This study investigated the effects of Goami 2 on the properties of Garaetteok. The moisture, crude protein, crude lipid and crude ash contents of the rice were 16.02, 5.40, 1.87 and 0.77%, respectively. The amylose contents (32.16%) and total dietary fiber contents (9.03%) were the highest in Goami 2. The water binding capacity of Goami 2 (167.84%) was higher than general rice flour. Using a rapid visco analyzer (RVA), the initial pasting temperature of Goami 2 was found to be the highest; also, the peak viscosities of Goami 2 were higher than general rice powder. To assess the effect of Goami 2 on the quality characteristics of Garaetteok, the rice-cake was made by adding various amounts of Goami 2 (0, 10, 20, 30, and 40% w/w) to rice. It was observed that higher the amount of added Goami 2, lower were the grades. In terms of the color values of Goami 2 addition, the L-values of Garaetteok were lower with increasing amount of Goami 2; addition of 40% Goami 2 had the lowest value. The textural properties (hardness) also showed that tteok containing the greater amounts of Goami 2 were considerably harder compared with the control. Sensory preference tests revealed that addition of less Goami 2 had the highest scores for appearance, color and overall acceptability, and the Goami 2 added was lower than control. Therefore, as compared to others cultivars, rice flour proved the most acceptable for the preparation of Garaetteok with cultivar rice.
