우리나라 수산 건제품중 발암성 N-Nitrosamine(NA)의 생성요인을 구명하기 위하여 시판 되고있는 소건품 10종(17개 시료), 조미건제품 1종(3개 시료), 자건품 3종(5개 시료), 염건품 1종(1개 시료), 동건품 1종(3개 시료) 및 해조류 2종(2개 시료)에 대하여 NA의 전구물질인 아민류, 질산염 및 아질산염을 분석하였고, GC(Gas Chromatography)-TEA(Thermal Energy Analyzer)를 이용하여 NA를 분석 정량하였으며, 또 GC-MS(Mass Spectrometry)로 N-Nitrosodimethylamine (NDMA)을 동정하였다. 수산 건제품의 아민류는 대체로 betaine질소가 다른 아민류에 비해 월등히 높아 건조 문어에서 $357.4{\sim}373.8mg\%$로 가장 많았고, 다음으로 건조새우 및 건조 오징어순이었다. 그러나 건조 해조류에서는 전혀 검출되지 않았다. TMAO질소는 $2.2{\sim}20.7mg\%$ 범위였으나, 건조해삼에서는 흔적량이었고, 건조 해조류에서는 전혀 검출되지 않았다. TMA질소는 TMAO질소에 비해 대체로 높게 정량되어 건조 상어에서 $57.2mg\%$, 건조 옥돔 $40.1mg\%$ 였으며, 그외 건조 해조류와 건조해삼을 제외한 모든 시료에서 $10.0mg\%$ 이상이었다. 분석된 시료중 dimethylamine(DMA) 역시 건조 해조류와 건조 해삼을 제외한 모든 시료에서 검출되었는데 비교적 함량이 높은 시료는 건조 상어(31.2 ppm), 동건 명태($22.9{\sim}24.3\;ppm$) 및 건조문어 ($17.9{\sim}18.4\;ppm$)등이었다. 질산염 질소는 불검출에서 최고 16.8 ppm범위였는데 건조 가오리(16.8ppm), 동건 명태(16.3ppm) 및 건조 오징어($2.2{\sim}12.4ppm$) 등에서 높은 함량을 보였으나, 그외 시료에서는 1.0 ppm미만이었다. 아질산염 질소는 질산염 질소에 비해 다소 낮은 경향을 보여 건조 해조류 및 건조 해삼에서는 전혀 검출되지 않았으나, 반면에 건조 가오리에서는 최고 9.6 ppm으로 정량되었다. NDMA의 농도는 시료간에 큰 함량차를 보여 건조 해조류 및 건조 해삼에서는 전혀 검출되지 않았으나, 건조 가오리($2.8{\sim}86.0ppb$), 동건 명태($8.2{\sim}55.5ppb$), 건조 오징어($3.3{\sim}53.2ppb$), 굴비(45.9ppb) 및 소건 새우($15.4{\sim}17.9ppb$) 등에서는 높은 함량을 보였으며 그외 시료에서는 10ppb미만 이였다. 대체로 NDMA가 높게 검출된 시료에서는 질산염과 아질산염질소의 함량이 높아 이들이 NBMA의 생성에 주된 요인이라는 것을 알 수 있었고, 동일 어종간에도 시료에 따라 함량차가 심한 것도 역시 질산염과 아질산염의 오염 정도에 의한 것으로 판단된다.

As a series of studies on improving the processing suitability of imported Pacific saury, oxidative stability of seasoned-dried Pacific saury treated with liquid smoke (T2 product) was examined during storage, comparing with control (C, seasoning only) and T1 (treatment of 0.05% BHT instead of liquid smoke). The pH of T2 treated with liquid smoke was relatively lower than those of C and T1 during storage. The contents of volatile basic nitrogen in all products increased continuously during storage. In the changes of TBA and POV of products during storage, the POV of T2 was lower than that of T1, and the TBA values of T1 and T2 were lower than that of C product. The major fatty acids were 22 : 1n-11, 20 : 1n-11, 16 : 0, 14 : 0, 22 : 6n-3, 20 : 5n-3, 18 : 4n-3, 16 : 1n-7, 14 : 1n-7 and 18 : 1n-9 in the both C and T2 products. The contents of polyunsaturated fatty acids in hath C and T2 somewhat decreased with increasing storage period, while those of saturated and monounsaturated fatty acids increased.

In the present study, we investigated the quality, sensory characteristics and commercialization potential of a rice collet snack made with the addition of dried shrimp. “Mild” and “spicy” snack products were produced with an edible oil coating and mixed seasoning powder coating, respectively. The approximate composition of the mild and spicy snacks, respectively, were 2.44% and 2.24% for moisture, 8.52% and 8.64% for crude protein, 18.36% and 26.54% for crude lipids, 1.28% and 1.38% for ash, 1.1% and 1.2% for salt, and 0.61 and 0.62 for pH. The L (lightness), a (redness), b (yellowness), and ⊿E (color difference) values were higher for the mild snack than the spicy snack. The mild and spicy snack had values of 7,776.4 and 7,655.8 mg/100 g for total amino acids, and 221.6 and 253.5 mg/100 g for total free amino acids, respectively. The TBA (thiobarbituric acid) value did not differ significantly between the two types of snack. The hardness value of the spicy snack was higher than that of the mild snack, but there were no significant differences in flavor between the two products. The sensory evaluation score of the spicy snack was slightly higher than that of the mild snack. Organoleptic inspection indicated that both snacks had a favorable, unique taste.

Efficiency of a far-infrared radiation (FIR) dryer for drying of citrus by-products (CBPs) was evaluated through their antioxidant activities. The CBPs dried through FIR were enzymatically digested by six carbohydrases (AMG, Celluclast, Pectinase, Termamyl, Ultraflo and Viscozyme) to prepare digests for evaluation of the activities. The total polyphenolic and total flavonoid contents of the digests were determined by colorimetric assays. The AMG digest was selected for the further experiments. The antioxidant potential of the digests were evaluated by DPPH, superoxide, hydroxyl and alkyl radical scavenging activities, $H_2O_2$ scavenging activity, metal chelating, lipid peroxidation inhibition and the reduction of DNA damage. The AMG digest from CBPs dried through FIR at $50^{\circ}C$ showed strong antioxidant activities in DPPH, superoxide, hydrogen peroxide, alkyl and metal chelating assays while all the digests showed strong lipid peroxidation activities. Further, enzymatic digests showed remarkable inhibitory activities against $H_2O_2$-induced DNA damage. Hence, the data obtained using different in vitro models clearly established the antioxidant potential of enzymatic digests from CBPs dried through FIR. Furthermore, they can be used as a source of natural antioxidants; hence, far-infrared radiation drying is a viable method for transforming wet CBPs into a dried form without destroying the bioactive components.

Recently, the new refrigerating system, using non - fluorinated hydrocarbon refrigerants has to be developed for the agricultural fields. One of that kinds of systems is the cooling system using the water vapor and vacuum, in which the water evaporate at the low temperature under vacuum and absorb the large amount of the latent heat. If vapor with large amount of latent heat is removed from the system, the system is cooled accordingly. The characteristics of cooling under the vacuum was observed and measured using experimental apparatus, which is consisted of vacuum chamber, the ejectors, the pumps and the measurement apparatus. As the results of experiments, we know that the evaporation in the vacuum occurs vigorously when the materials to be cooled has more amounts of heat before cooling, and by which effects the materials can be cooled. The cooling vacuum system is more efficient than other methods when the agricultural products is chilled or dried.
