Spices are used to enhance the taste of Korean food. The term "Yangnyeom" contains a wishful meaning that it would be as good for health as medicine when eaten. It is prescribed as a medicine to heal disease according to the ancient medical books. Fifteen spices in Korean food such as vinegar, liquor, honey, water, wheat-gluten, sesame, sesame oil, garlic, green onion, ginger, mustard, pepper, cinnamon, soy sauce, salt, cheoncho, and others are prescribed as medicine for internal and external uses for almost every disease. To examine these spices, the subjects were treated with either the spice-boiled water or spice-mixed water, or applied externally. It is suggested that spices that are produced through peculiar traditional cooking method, fermenting, and those that have long-growth period, grew in the natural environment, and the like have efficacy as medicine. Spices can be sufficiently applied as emergency medicine, disease-treatment, subsidiary supplement, and preventive medicine.

To develop a value-added individually quick frozen (IQF) intermediate product from cultured sea mussel Mytilus edulis, we prepared IQF half-shelled roasted sea mussels (HRM) and IQF half-shelled boiled sea mussels (HBM). The processing conditions and quality metrics of the mussels were examined. The HRM and HBM were produced by washing and removing the byssus of raw sea mussels, followed by electric roasting or boiling. The roasted or boiled sea mussels were half-shelled, lightly washed with 3% saline water, rapidly frozen for 2 hours at -35℃, glazed, and packaged with a plastic film bag. The HRM and HBM had volatile basic nitrogen contents of 11.5 and 12.6 mg/100 g, and amino nitrogen contents of 607.9 and 534.2 mg/100 g, respectively. The HRM and HBM had hardness values of 4.31 and 2.99 kg/㎠, shearing force values of 992.2 and 507.7 g, free drip values of 8.9% and 10.2%, and expressible drip values of 7.0% and 8.1%, respectively. The free amino acid contents of the HRM and HBM were 763.1 and 560.7 mg/100 g, respectively. These results demonstrate that HRM have superior qualities compared to HBM and can serve as high-end shellfish when cooked.

The purpose of this study was to evaluate the effects of routine haecho bibimbab (boiled rice with assorted seaweed mixtures) consumption on the bowel habits in humans. Forty free-living adults (female 38, male 2) participated in this study (mean age $41.2\;{\pm}\;7.5$). After a baseline survey on general characteristics, life style and dietary habits, the participants were asked to consume haecho bibimbab during two-week period for lunch. Habitual bowel movements were checked out every day by a questionnaire and nutrient intake was estimated by a 24-hour recalls before and after the study. After 2 weeks of clinical trial, the bowel habits had improved. Haecho bibimbab increased the number of bowel movements, changed hard stools into softer ones. It also lessen the sense of incomplete evacuation, and abdominal pain during defecation, increased water intake (p < 0.001) and improved gastrointestinal problem. The participants believed that haecho bibimbab was effective in improving their constipation symptoms and bowel habits (p < 0.01). Routine haecho bibimbab consumption tended to increase especially vitamin A, E and folate intake (p < 0.01). The present findings suggest that routine seaweed-based lunch meal (haecho bibimbab) consumption may improve bowel habits without side effects.

Purpose: The objective of this study was to provide nutritional information (protein and amino-acid contents) of soybeans (Baktae, Seoritae, Huktae, and Seomoktae) with different cooking methods. Methods: Raw, boiled (in $100{\pm}15^{\circ}C$ of water for 4 hr), and fried (in a pan at $110{\pm}15^{\circ}C$ for $20{\pm}5min$) soybean samples were prepared. Contents of protein and amino acids were determined. Results: Protein content in raw Baktae, Seoritae, Huktae, and Seomoktae soybeans ranged from 361.0 to 386.8 mg/g. Protein contents differed according to cooking methods. They were higher in pan-fried beans (107.9-113.5%) than in raw or boiled soybeans (48.2-49.5%). A total of 18 amino acids were analyzed. Amino acid data sets were subjected to principle component analysis (PCA) to understand their differences according to soybean types and cooking methods. Bean samples could be distinguished better according to cooking method in comparison with bean types by principle component (PC1) and PC2. In particular, fried soybeans contained much higher levels of cystein. Other amino acids were the dominant in raw and boiled ones. On the other hand, the amounts of threonine, histidine, proline, arginine, tyrosine, lysine, tryptophan, and methionine were higher in raw bean samples than in cooked ones. Conclusion: The contents of amino-acids and proteins are more effected by different cooking methods in comparison with soybean types.

This study was carried out with sardine to develope a new type of fish protein concentrate. Chopped sardine meat was thermally treated in two different ways, autoclaved at $121^{\circ}C$ for 1 min and boiled at $95^{\circ}C$ for 5 min. The heat treated meat was pressed, controlled to PH 7.8 with $3\%$ (w/v) of $NaHCO_3$ and hot-air dried(at $40^{\circ}C$). The dried meat was powdered (50mesh), air and vacuum packed in laminated film bag(PET/AL. foil/CCP) and stored at room temperature for 60 days. The results of product quality analysis are as follows : 1. Proximate contents of moisture, crude lipid and protein of the autoclaved and boiled product were in the range of $10.0{\~}10.2\%,\;9.0{\~}9.1\%$ and $73.8{\~}74.4\%$, respectively. Yields of the both products were $40\%$ and $32.5\%$. 2. Values of emulsion activity, emulsion stability and foam expansion of the autoclaved product were $48.7\%$, $44.1\%\;and\;44.0\%$, respectively. These values were higher than those of boiled product. 3. Water holding capacity and digestibility of the both products were in the range of $5.0{\~}5.3\%$ and $78.0{\~}78.2\%$, respectively.

The optimum conditions for selective .elimination of salt from tuna boiled extract (TBE) by electrodialysis were determined. The desalination conditions of TBE were determined at various pH's, concentrations and volumes of TBE. The ion-exchange membrane with a molecular weight cut off 100Da was used for desalting of TBE. The desalination times on $1\%$ and $10\%$ of TBE concentrations were 40 min and 240 min, respectively. The electrodialysis process could removed above $95\%$ of the initial salt content in $1\%$ and $10\%$ of TBE concentrations. The desalination of TBE at pH 4.0 was $14\%$ higher than that at pH 9.0 The amount of water transferred by the electrodialysis was determined. The electrodialysis process could remove above $90\%$ of the initial salt content in $5\%$ TBE for 80 min. The initial volume and the permeate did not have significant effects on desalination time and ratio. The key parameters for the desalination of TBE were pH and concentration of TBA.

The effects of heat treatment on the physical and physical and physiological properties of wax gourd (Benincasa hispida) were examined. The applied heat treatments were autoclaved at $121^{\circ}C$ for 1 hr, boiled for 30 min, and microwaved at 680 W for 5 min. The water retention capacity (WRC) of the wax gourds was 9.43 g/g for the microwaved samples, 5.12 g/g for the boiled samples, 4.63 g/g for the raw samples, and 2.61 g/g for the autoclaved samples. Heat treatment caused to increase swelling by up to $4.4{\sim}7.8\;mL/g$. Calcium binding capacity of heat-treated wax gourd increased in the order of microwaved, boiled, raw, autoclaved samples. Scanning electron microscopy (SME) showed that autoclaving caused the most severe structural modifications, while microwave treatment produced the least modifications. The retarding effect on glucose and bile acid transport depended on the heat treatment. Only boiling showed the glucose retardation effect. Bile acid retardation effect increased in order of boiling (22.9%), autoclaving (17.1%), microwave treatment (14.3%), and raw wax gourd (8.6%). The cadmium retardation effect was significantly high in all samples.
