A chitosan-degrading fungus, BSF114, was isolated from soil. The culture preparation showed strong chitosanolytic enzyme activity at an optimum pH of 4.0 and optimum temperature of $60^{\circ}C$ after 36-40 h fermentation. The rapid decrease in the viscosity of the chitosan solution early in the reaction suggested an endo-type cleavage of the polymeric chitosan chains. To identify the isolated fungus, molecular biological and morphological methods were used. The fungal internal transcribed spacer (ITS) region 1 was amplified, sequenced, and then compared with related sequences in the GenBank database using BLAST. The phylogenetic relationships were then analyzed, and the results showed that the fungus belongs to Aspergillus fumigatus. Morphological observations were also used to confirm the above conclusion. The chitooligosaccharides (COS) obtained through hydrolyzing the colloidal chitosan showed that A. fumigatus BSF114 is suitable for degrading chitosan and producing chitooligosaccharides on a large scale. High concentrations of the COS (1,000 and 500 ${\mu}g/ml$) significantly proliferated mice marrow cells.

본 연구는 인천광역시내 유통되고 있는 기타가공품에 대하여 중금속 (납, 카드뮴, 수은), 부정유해물질 (발기부전치료제와 그 유사물질 36종, 비만치료제 3종, 스테로이드 28종)을 조사하여 안전성을 평가하고, 기타가공품에 대한 기준규격 제정 시 기초자료로서 제공하고자 실시하였다. 그결과 부정유해물질은 검출되지 않았고, 중금속은 납(Pb) 0.001~13.39(mg/kg), 카드뮴(Cd) 0.003~1.231(mg/kg), 수은(Hg)은 0.001~0.650(mg/kg)의 결과를 얻었다. 기타가공품은 중금속에 대한 규격 기준이 없으므로, 중금속의 국내 외 기준을 비교하였을 때 중금속 최고기준을 적용하면 납(Pb)과 수은(Hg)에서 각각 2건씩 4건이 초과되는 것으로 확인되었다. 검사결과를 바탕으로 한 중금속의 위해성 평가는 FAO/WHO (Codex)의 잠정주간섭취허용량(PTWI)과 비교결과, 해물파전믹스, 들깨가루는 Pb의 PTWI의 기준 0.214를 초과하였다. 결론적으로 분말류나 환제품을 유사식품 기준으로 적용하면 부적합으로 판정 될 수 있기 때문에 규격검사를 피할 목적으로 기타가공품으로의 등록을 지향한다. 이를 악용할 경우 검사의 사각지대로 인해 시민의 건강이 위협받을 수 있다. 따라서 품목제조허가 신고시 규격외 일반가공식품에서 기타가공품으로의 등록을 지양하고, 기타가공품의 세부적인 검사규격을 제정하여 관리해야 함을 제언한다.

This study investigated the possibility of reducing sodium and sugar intake in the Bulgogi bowl and yogurt, respectively, by utilizing food and non-food factors. Sodium and sugar replacers were the target food factors, and eating environment was the target non-food factor. The sodium content of Bulgogi bowls was reduced by 40%, and a flavor enhancer was applied to compensate for the reduced saltiness. Low calorie sweeteners, such as sucralose and stevia, were used to lower the sugar content of yogurt by 30%. Consumers were asked to evaluate the samples in one of the three eating environments: private booth evaluation, BOOTH; watching video clips during evaluation, VIDEO; conversation with friends during evaluation, FRIEND. The results showed that applying sodium or sugar replacers were effective in lowering sodium or sugar intake, respectively, without compromising the acceptance level of samples.
