본 연구는 돈육의 비인기 부위를 기준으로 하고, 우육을 일부 배합하여 관능적 특성을 살린 돈육과 우육의 적절한 배합비를 결정하여 재구성 반건조 육포를 제조하여 품질 특성을 조사하는 데에 있다. 전체적으로 배합비에 상관없이 케이싱으로 충전 후 제조한 재구성 반건조 육포중 셀룰로오즈로 제조한 재구성 육포가 건조가 잘 이루어져 수분 함량($32{\sim}36%$)과 수분활성도($0.83{\sim}0.85$)가 가장 낮아 전단력이나 metmyoglobin 함량이 높았으나 관능 평가에서 대체로 좋은 평가를 받아 재구성 반건조 육포 제조에 가장 알맞은 성형틀로 선택하였다. 또한 원하고자 하는 결착력이 좋고 조직감이 개선된 재구성 반건조 육포의 배합비에 있어서 T-3 배합비인 돈육과 우육의 비율이 90:10 이며, 결합육으로서 돈육과 우육이 5:5의 비율을 유지하였을 때, 이화학적 특성 및 관능적 특성에 있어서 재구성 반건조 육포로서 가장 좋은 평가를 받았다.

The quality characteristics of semi-dry red pepper (SDRP) (Capsicum annuum L.) were compared with raw and dry red pepper (DRP). Raw red pepper was divided into pieces and the semi-drying treatment involved air-drying at $65^{\circ}C$. The study focused on describing the characteristics of semi-dry red pepper in comparison with dry red pepper. Factors considered were reduced drying period, ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content. ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content of SDRP were higher in SDRP than in DRP for 15 g or less water per 100 g. Red pepper powders made using the semi-drying method showed the highest amount of glucose and vitamin C. Capsanthin content in SDRP (151.6155.9 mg/100 g) was significantly higher than for DRP (133.4 mg/100 g). The capsaicinoid content of SDRP was about 13-25% higher than in DRP. The ASTA values (148.7159.3) for SDRP were much higher than for DRP (139.5). The vitamin C and free sugar content of SDRP was 40-76% and 20-40% higher, respectively, than for DRP. and $20{\sim}40%$, respectively, by SDRP compared to DRP.

We compared two kinds of red peppers, semi-dry red popper and hot air dry red pepper, and made two kinds of Kimchies with them for this study. The semi-dry red pepper is better to maintain natural color of raw red pepper, to keep hygenity and to protect its loss of the nutrition, than the hot air dry red pepper. The results are as follows: The content of vitamin C and ASTA color value in semi-dry red pepper powder were much higher than those in hot air dry red pepper The cell numbers of total bacteria in semi-dry red pepper powder were much lower than those in hot air dry red pepper. The changes in quality of the two Kimchies were evaluated by pH, acidity, total microbes, lactic acid bacteria cells count and sensory. The patterns of changes in pH, acidity, total microbes and lactic acid bacteria cells count of two kinds of samples were the same. But in case of sensory evaluation, Kimchi made with semi-dry red powder showed best sensory scores than of all in overall acceptability.

This study was carried out to examine the optimum processing conditions of seasoned semi-dried oyster, and to investigate its food component characteristics. Three types of semi-dried oyster were prepared: semi-dried oyster prepared without seasoning and coating (C), seasoned semi-dried oyster without coating (S) and seasoned semi-dried oyster coated with alginate (SA). SA was high in moisture (48.6%), while low in lipid (2.8%), and crude protein (25.9%) compared to those of C and S. Hardness and sensory scores of SA were $209.8g/cm^2$ and $3.9\sim4.5$ points, respectively. Total amino acid content (24,299 mg/100 g) of SA was lower than that (27,181 mg/100 g) of C, and the major amino acids were aspartic acid, glutamic acid, leucine and Lysine. The major fatty acids of SA were 16:0 (25.5%) as saturates and EPA (23.5%) and DHA (9.3%) as polyenes. Calcium and phosphorus contents of SA were 42.6 mg/100 g and 245.5 mg/100 g, respectively.

Mulberry fruit is common to keep a frozen storage because of the very high water content. Because freezing-storing cost is generated before the processing or sales, farmers of mulberry fruit production are weighted in financial burden. In addition, mulberry fruit has difficulty in expanding consumption by made in the simple processed products like the mulberry jam, mulberry juice, mulberry enzyme, alcohol, etc. Recent, frozen fruits including frozen blueberries, frozen strawberries, frozen mango, frozen rich, frozen mulberry fruit has been started to sell in the large discount stores and convenience stores. However, there is restricted sales in only special place that have the frozen distribution facilities. So, for the income improvement and consumption promotion of mulberry farmers facing these difficult situations, we developed the processing method of semi-dried mulberry fruit using the vacuum freezing dryer. The frozen mulberry fruit which was stored below $-40^{\circ}C$ is to dry in a vacuum freeze dryer, at $30{\sim}35^{\circ}C$, 23 ~ 24 hours. Semi-dried mulberry fruit seperated respectively. It had soft texture, and maintained shape, size and flavor. In particular, semi-dried mulberry fruit can be stored at room temperature.

This research investigated the application of semi-dried red pepper in Kimchi manufactured using semi-dried red pepper with seed ratios of 20, 40, 60 or 80%. Among the treatments, there were no significant changes in pH, acidity and lactic acid bacterial cell counts during the fermentation period. Kimchi made with a higher pericarp ratio had higher levels of vitamin C, ASTA value and capsainoids during fermentation. The organic acid level showed no significant difference with the various semi-dried red pepper seed ratios, and during fermentation the malic and succinic acid levels decreased while the acetic and lactic acid levels increased. In a sensory evaluation, the overall acceptance was highest for the control group, but the acceptance of Kimchi prepared with semi-dried red pepper at a seed ratio lower than 20% was not significantly different.

A study was conducted to investigate the possibility of processing seasoned and semi-dried right-eyed flounder (Pseudopleuronects herzensteini) and to examine its quality during storage at $\pm$$3^{\circ}C$ by analyzing the factors such as moisture content, pH, volatile basic nitrogen (VBN), viable cell count and peroxide value (POV). For processing of the seasoned and semi-dried product, optimum conditions of drying temperature and drying time were $20^{\circ}C$ and 4 hrs, respectively, under 50$\pm$5$\%$ of relative humidity and 2 m/sec of air blast speed. The shelf-lives of the products by vacuum-packaging method in nylon/polyethylene/linear low density polyethylene (0.015/0.045/0.040 mm) laminated film bag were 35 and 16 days during storage at $-3^{\circ}C$ and $3^{\circ}C$, respectively.

This study was conducted to produce a new red ginseng by steaming ginseng using a new pre-treatment method, so as to develop ginseng products with improved flavor and thereby expand ginseng's consumer base. The color parameters (Hunter value), free sugar contents, and ginsenoside contents of the powder from the dried red ginseng, and the sensory test of the semi-dried red ginseng and the decoction from the dried red ginseng, were measured to investigate the effect of acid (ascorbic acid or citric acid) impregnation pre-treatment on red ginseng. The powder from the acid-pretreated red ginseng became lighter and more yellow than the red ginseng that was not pre-treated, but the redness (avalue) of the powder from the acid-pre-treated red ginseng increased. The ginsenoside contents of $Rg_2+Rh_1$ and $Rg_3$ increased with the acid treatment. There was a significant difference in the color and sweetness of the semi-dried acidtreated and non-treated red ginsengs in the sensory test. As the results of the sensory test were expressed in the hedonic scale, however, there were significant differences in the degrees of bitterness, astringency, sourness, odor, and color of the red ginseng decollation. Especially, the acid-treated red ginseng extract tasted less bitter, which shows the potential of new red ginseng products with improved ginseng flavor.
