Abstract

We investigated quality characteristics of microencapsulated $\beta$-carotene prepared by different molecular weight chitosan (8 kDa, 43 kDa, and 67 kDa), cyclodextrin, and maltodextrin. As the chitosan content and molecular weight increased, viscosity were increased. pH was decreased as the chitosan molecular weight increased. The particle size and form of microencapsulated $\beta$-carotene were $26.55{\sim}109.8{\mu}m$ and generally globular form. The microencapsulrated $\beta$-carotene that were stored for 5 weeks at room temperature presented L value and a value were decreased and b value was increased. When the light is blocked, the stability was maintained. As the chitosan molecular weight increased, $\beta$-carotene content maintain stability. The 67 kDa chitosan with a higher molecular weight is anticipated to be a widely utilized wall material in the functional food industries.

기능성 소재로 산업적으로 이용되고 있는 키토산을 고부가가치 기능성식품의 피복물질로의 활용가능성을 확인하기 위하여 핵물질로 $\beta$-carotene을 사용하여 미세캡슐화하였으며 저장기간에 따른 품질 안정성을 조사하였다. 키토산의 점도는 분자량 및 농도가 증가함에 따라 증가하였으며 pH값은 분자량이 증가함에 따라 낮아짐을 알 수 있었다. 분무건조 분말의 평균 입자크기는 $26.55{\sim}109.8{\mu}m$이였고, 분자량이 증가함에 따라 증가하였으며, 입자모양은 전반적으로 구형의 모양을 보여주어 분말 흐름성이 양호할 것으로 사료된다. 저장안정성을 확인하기 위하여 5주간 상온에서 알루미늄 호일로 포장한 구간과 미포장한 구간에서의 색도 및 $\beta$-carotene 함량을 분석한 결과, 저장기간에 따라 L값 및 a값은 전반적으로 감소하였고 b값은 증가하였다. 키토산의 분자량이 증가할수록 L값 및 a값의 감소율은 낮았으며 CD 및 MD와 유사한 감소율을 보여주었다. 저장기간에 따른 미세캡슐 분말의 $\beta$-carotene 함량 변화는 키토산 분자량이 증가할수록 감소율이 낮았는데, 67 kDa가 저장안정성이 가장 우수하였으며 저분자 키토산인 8 kDa 또한 CD와 MD와 유사한 감소율을 보여주었다. 저장조건에 따른 $\beta$-carotene 함량은 알루미늄 호일 포장한 구간이 미포장한 구간에 비해 높았으며 알루미늄 호일로 포장된 67 kDa 구간이 CD 및 MD에 비해 3배 가량 높음을 확인하였다. 따라서 키토산은 미세캡슐용 피복물질로서의 우수한 저장안정성을 가짐을 확인하였으며 향후 다양한 기능성식품개발에 활용 가능할 것이다.
