  • To determine chemical components and meat quality traits related to palatability of 10 primal cuts, 25 Hanwoo carcasses were selected from 5 carcasses × 5 quality grades and used to obtain proximate data and meat quality characteristics. Significant differences (p<0.05) in chemical component and meat quality were found among the 10 primal cuts. The highest fat content was found in the kalbi, followed by dungsim, yangjee, chaekeut, ansim, abdari, suldo, moksim, udun, and satae. Protein and moisture contents in the 10 primal cuts were in reverse order of fat content. Moksim had the highest drip loss % and cooking loss % than all other primal cuts while kalbi showed the lowest (p<0.05) percentage of drip and cooking loss. Ansim had the longest sarcomere length but the lowest shear force values than all other cuts (p<0.05). The highest (p<0.05) score for overall acceptability was observed in ansim. Moksim, udun, abdari, and satae were rated the lowest (p<0.05) in overall acceptability among the 10 primal cuts from Hanwoo carcasses. In conclusion, ansim, dungsim, chaekeut, and kalbi had the highest overall acceptability due to their higher fat contents and lower shear force values.

  • To develop Korean-style cut noodles with enhanced protein and calcium levels, we manipulated the ratio of dried anchovy Engraulis japonicus soup base residue powder to wheat flour, using a response surface methodology based on trained panel trials to determine the optimum ratio. Texture analysis and nutritional evaluation were also performed on cut noodles containing dried anchovy soup base residue (CNAR). Higher umami taste and springiness, and lower fishy flavor were strongly correlated with overall acceptability. The optimal CNAR formulation consisted of wheat flour (96.02 g), anchovy residue powder (2.67 g), and water (50.64 mL). CNAR had lower gumminess and adhesiveness (P<0.001), but higher springiness, cohesiveness (P<0.001), and chewiness (P<0.05), than the control (original wheat flour cut noodles). The addition of anchovy soup base residue elevated protein, lipid, and ash levels relative to the control. Color values decreased with increasing residue powder content. In vitro protein and starch digestibility of CNAR were lower than in the control (P<0.001). CNAR yielded significantly higher total free amino acid content than the control (P<0.01), leading to CNAR's improved palatability. Dried anchovy soup base residue can be used in wheat flour cut noodles to improve nutrition, sensory acceptability, and profitability.

  • This research studied the effects of Backryeoncho (Opuntia ficus-indica var. saboten) extract as an additive in kimchi in various amounts (0%, 0.4%, 0.8%, 1.2%), and its acceptance by middle school students in the Jeonju area. The treated kimchi had a higher pH than the untreated kimchi without extract, and the titratable acidity of the kimchi decreased with the addition of the Backryeoncho extract. The degree of salinity decreased in kimchi with the added Backryeoncho extract in a dose-dependent manner. The cutting force and compression force were higher in kimchi where the extract was added during the fermentation period resulting in improved texture of the kimchi. The addition of the extract slowed growth of total bacteria (1.83~2.12 log CFU/mL) and lactic acid bacteria (1.4 log CFU/mL) as compared with the control sample. In the sensory evaluation of overall taste, kimchi with 0.8% extract added demonstrated higher evaluation in overall categories. The acceptability of Backryeoncho extract as an additive in kimchi among middle school students was higher than in the control sample, with an optimum additive of 0.4% extract, based on the lowest volume of leftovers.

  • Korean traditional meat patties (Tteokgalbi) were prepared by replacing part of the lean meat content with either pork backfat or canola oil and the effect of substitution on sensory quality of the meat patties was investigated. Compared to the control patties, pork-loin Tteokgalbi with 10% pork backfat or 10% canola oil had significantly higher overall acceptability and higher perceived intensity of meat flavor, sweetness, umami, and oiliness. The pork-loin patties containing 10% fat also had lower perceived firmness, toughness, and chalkiness of than the control Tteokgalbi. The chicken breast Tteokgalbi with 10% canola oil had the lowest perceived firmness and chalkiness (control > pork backfat > canola oil). No significant difference was noted in the overall acceptability of chicken breast patties with 10% pork backfat and those with 10% canola oil. These results indicate that substituting 10% of lean meat of Tteokgalbi with fat improved the sensory acceptability of the product for Korean customers regardless of the lean meat and/or fat source used in the patties. Lean meat patties formulated with a limited amount of vegetable oil such as canola oil can be a healthy option for Korean consumers by providing desirable fatty acid profiles without sacrificing sensory quality of the product.

  • The purpose of this study was to investigate the quality characteristics of Kugija-Injeulmi by varying the ingredient ratio of Lycii fructus powder (4, 6 and 8%). According to sensory evaluation of Kugija-Injeulmi, as the ratio of Lycii fructus powder was increased, the bitterness, hardness and chewiness all increased. It was found that Kugija-Injeulmi made of glutinous rice was moistened and softened with the addition of more Lycii fructus powder, but it was rougher than Kugija-Injeulmi made of glutinous rice flour. As a result of textural analysis of Kugija-Injeulmi, the hardness, adhesiveness, gumminess and chewiness increased as the amount of Lycii fructus powder increased, whereas the cohesiveness decreased. Kugija-Injeulmi made of glutinous rice was moister than Kugija-Injeulmi made of glutinous rice flour. The overall-acceptability was negatively correlated with coarseness. The overall-acceptability of Kugija-Injeulmi made of glutinous rice was much higher than that made of glutinous rice flour. From the above results, the most advisable mixture ratio of Kugija-Injeulmi is as follows Kugija-Injeulmi add 282g (94%) glutinous rice flour, Lycii fructus powder 18g (6%) and salt 3g. The moisture content was 42.22%.

  • This study investigates the characteristics of mayonnaise adding yuza juice, a byproduct of yuza tea, to it. The mayonnaise was prepared by adding yuza juice at 0(control), 25, 50, 75, 100%. In order to analyze the characteristics of the mayonnaise, we examined the color, viscosity, emulsion stability and sensory acceptability. The L, a, ${\Delta}E$ values of mayonnaise mixed with yuza juice were similar to or lower than control. As the content of yuza juice increased, the viscosity and emulsion stability, that is the physical quality of the mayonnaise, improved significantly(p<0.05). With regard to sensory evaluation, mayonnaise mixed with yuza juice had better flavor, taste, texture and overall acceptability(p<0.05). These results suggest that yuza juice is good ingredient to improve the quality and sensory acceptability of mayonnaise.
