  • This study examined variations in postmortem meat quality characteristics and consumer sensory evaluations of different pork quality classes in fresh and cooked meat. Pale, soft, and exudative (PSE) meat had the highest drip loss, lightness, and the lowest $pH_{24\;hr}$ whereas dark, firm, and dry (DFD) meat showed the opposite results. When the fresh meat was evaluated by consumer panelists, they could only distinguish the PSE class of meat and it scored lowest in overall acceptability. However, the panelists did not consider cooked PSE or DFD pork to be unacceptable overall, indicating that consumers cannot distinguish the quality of cooked pork.

  • Tenderization of beef by the addition of barks(Morus alba Linne) and its sensory properties were observed by shearing test, cooking loss, pH, protein content and sensory evaluation. Shear force was decreased as the addition level of barks (Morus alba Linne) increased. Tenderization effect of beef was increased 8,8% at the addition level of 2.5%, 25% at 5.0%, 4.7% at 7.5%, 58% at 10% barks(Morus alba Linne). Cooking loss was observed 44.50% at the no addition, 45.3% at 2.5%, 45.8% at 5.0%, 47.5% at 7.5%, 50.0% at 10% addition level of barks (Morus alba Linne). As the addition level of barks(Morus alba Linne) increased pH of cooked beef decreased to the range of 5.6 to 5.46. As the addition level of barks (Morus alba Linne) increaed protein content of beef decreased whereas protein content of cooled liquor increased. The addition of barks(Morus alba Linne) improved the sensory quality of cooked beef. Especially, tenderness scored the highest value in 10% added beef and other quality factors color, flavor, juiciness and overall quality were evaluated significantly high in 5% added beef. Therefore 5% addition level of barks(Morus alba Linne) for cooking beef was suggested as the desirable level of addition.

  • Vinegar and/or sake are often added for preservation hurdle in Korean seasoned beef product, affecting sensory quality. Sous vide packaging formerly developed requires optimization of formulation recipe in these ingredients. Therefore this study looked into the effect of vinegar and sake on the sensory quality attributes by response surface methodology. The addition of vinegar lowered the product pH significantly but sake addition did increase it slightly. Water activity did not change with the addition of these. Ten day storage at $8^{\circ}C$ did not make any significant changes in salt content and water activity. The added vinegar and/or sake in the formulation degraded the hedonic sensory scores of the product. The storage of the product made the degradation effect less pronounced. For the stored product the effect of sake on taste, texture and flavor was greater than that of vinegar. The respective addition of vinegar and sake less 4.0 and 4.5% could maintain the required sensory quality and thus was suggested in this study as their affordable use level for preservation hurdle.

  • Bulkogi(roast beef) seasoning stored without cap at 5$^{\circ}C$ and 23$^{\circ}C$ and within capped boule at 5$^{\circ}C$, 23$^{\circ}C$, 38$^{\circ}C$, 48$^{\circ}C$ and heat cycling(38$^{\circ}C$-1 week and 5$^{\circ}C$-1 week) and investigated sensory quality, pH, VBN, amino-N, surface color, and viable cell counts during 6 month storage. Nonpackaged Bulkogi seasoning was deteriorated by molds after 2 weeks at 23$^{\circ}C$ but did not showed any significant quality changes at 5$^{\circ}C$ for 1 month. Sensory scores of packaged sample rapidly declined with the temperature increase but chemical criteria was not significantly changed depending on temperature and storage time. Correlations between sensory scores and chemical parameters was not found, but sensory scores on color was correlated with lightness(L. value) of surface color(r=0.899). Heat cycle storage resulted in similar changes in quality to 38$^{\circ}C$ storage. Ql0 values calculated by sensory evaluation results as a quality index was 6, and the shelf-life of packaged Bulkogi seasoning was predicted 88 months at 23$^{\circ}C$.

  • The Purpose of this study was to propose the most effective packaging method and storage conditions to apply to home-delivered meals for the elderly Changes in the physical and sensory qualities of pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok, in wrap packaging, top sealing and vacuum packaging were evaluated during storage at 25, 4 and -18$^{\circ}C$, for 5 days. The speed of falling-off in the foods qualities, under chilled and frozen storage conditions did not differ much as the 5 day storage period was too short for a proper assessment. The sensory characteristics of taste and texture were better evaluated in the chilled than in the frozen storage. The most effective packaging method at all the storage temperatures was the vacuum packaging, which assured the safety of the foods by the removal of oxygen. The lightness, springiness and hardness were significantly influenced by the storage temperature, period and packaging method, while the sensory characters were affected by storage temperature and the period. In conclusion, the quality of the vacuum packed pan fried oak mushroom and meat and soy sauce glazed hair tail, in frozen storage, were still fresh after the five days of the experiment. The shelf-life of those foods with wrap packaging, in chilled storage, were suggested to be three days. The quality of the roasted dodok, with vacuum packaging in chilled storage, was preserved for five days.

  • This research investigated the sensory processing ability and selected subjects who had sensory processing problems, and divided the subjects into an experimental group and control group. The experimental group was educated with sensory processing intervention on the activities of daily living to determine its influence on the quality of life. The study was based on 230 university students with similar majors in 3 universities of Chungcheong area in the beginning of May, 2013. From here, 32 subjects who had issues with their sensory processing ability were selected. The 230 students were given a survey on the quality of life, individual characteristics, and sensory processing ability. Later, the 32 subjects who had problems with their sensory processing ability were divided into an experimental group and control group. The control group performed sensory processing intervention, whereas the control group did not. After the sensory processing intervention method for 6 weeks, the quality of life was re-evaluated. As a result, the total score of the quality of life after intervention was 98.69 in the experimental group and 84.81 in the control group (p=0.001). The physical score was 16.43 in the experimental group and 14.64 in the control group (p=0.008). The psychological score was 14.71 in the experimental group and 11.75 in the control group (p<0.001). The social score was 14.67 in the experimental group and 13.17 in the control group (p=0.032). The environment score was 14.66 in the experimental group and 12.34 in the control group (p=0.006). The experimental group showed a significant increase in all areas of the quality of life, whereas the control group did not. Through this result, it can be seen that a sensory processing intervention method in daily life can increase the quality of life for subjects with problems in sensory processing ability. Overall, it will be necessary to apply a treatment of various sensory intervention programs for adults and promote a better quality of life.

  • Gochujang samples with essential oils were evaluated for sensory including taste and, smell during various storage periods with the aim of developing improved high value-added products. The sensory testing was performed on Gochujang with 0.005% Zanthoxylum piperitum and Chrysanthemum indicum essential oils, extracted through steam distillation. During storage at 4 and $20^{\circ}C$ for 8 weeks, sensory testing was performed at 0, 1, 2, 4 and 8 weeks by trained panelists. Overall quality decreased in Gochujang samples containing Z.piperitum essential oil and increased in samples containing C.indicum essential oil, at 4 and $20^{\circ}C$. Samples stored at $4^{\circ}C$ were quality more then those stored at $20^{\circ}C$. Sensory evaluation was highest for Gochujang with C.indicum essential oil stored at $4^{\circ}C$. It is concluded that functional Gochujang can be developed by adding small quantities of essential oils. Increasing the amount of essential oil added is likely to affect the innate taste and flavor of Gochujang.
