본 연구는 특수용도식품에 함유되어 있는 비타민B12와 비오틴에 대하여 식품의 복잡한 매질 특성에 특이성을 확보할 수 있도록 현행 식품공전 시험법을 개선하고자 하였다. 식품공전에서 비타민B12와 비오틴의 시험법에 항체반응을 통해서 분석물질과 특이적으로 결합하여 그 외의 성분들을 효과적으로 제거할 수 있는 면역친화성 컬럼을 도입하여 시험용액을 정제 및 농축함으로써 전처리 과정을 개선하였다. 식품 등 시험법 마련 표준절차에 관한 가이 드라인에 따라 밸리데이션(특이성, 직선성, 검출한계, 정량 한계, 정확도, 정밀도)을 수행하고 개선된 시험법을 이용하여 유통 중인 특수용도식품의 대상 품목에 대해 시험법 적용여부를 확인하였다. 본 연구사업의 수행으로 시험·검사의 정확성을 증대시켜 특수용도식품 품질관리에 대한 신뢰성을 더 높일 것으로 본다.

The purpose of this study is to predict the economic size of foods-for-elderly market, which will be valuable information for establishing related policy and backup system. After setting the scope of related industry, detailed information for current market situation was investigated and a systematic forecast for market changes in the future was performed. Economic growth, changes in consumer expenditure and economic status of the elderly, current subscription of medical insurance and saving for pension were reflected. In addition, a survey toward related firms was completed and changes in aged population and incidence of chronic disease in the elderly were taken into account. Results show that the annual growth rate of the market was predicted to be the minimum 4.54% through the maximum 8.32% from 2010 to 2025 and its market size was forecasted to be the minimum 7,073 ten million won through the maximum 10,976 ten million won. It is expected that the market of foods-for-elderly will grow rapidly with development of foods technology and fast increase of aged population. Especially, growth of health functional foods and foods for special dietary uses for elderly will be distinguished. However, it seems that related firms are on the hedge, watching current trend of the related industry. This may results in insufficient supply against the demand. Therefore, policy for foods-for-elderly should be introduced and systematically administered, including R&D support, standardization and authentication for foods-for-elderly, construction of related database system.
