Abstract
Attempts were made to evaluate possibilities of adding water soluble chitosan to milk for improving functionality of milk, and physico-chemical and sensory properties of chitosan added milk were studied. pH and acidity of milk with ethyl alcohol washed chitosan were close to those of control. Color and consistency of chitosan added milk were better with chitosan of lower molecular weight than with high molecular weight. Chitosan of high molecular weight resulted in increased consistency and browning of milk. Milk with less than 1.0% chitosan could be sterilized at
수용성 chitosan의 응용범위 확대 및 기능성 강화식품 개발을 위하여 시유에 수용성 chitosan을 첨가하여 이화학적 및 관능적 특성을 조사하였다. 수용성 chitosan을 첨가한 시유의 pH와 산도는 ethyl alcohol로 세척한 chitosan을 사용하면 신선유에 적합한 품질을 나타내었다. 점도와 표면색도는 chitosan의 분자량이 작을수록 좋은 품질을 보였으며, 분자량이 커질수록 점도의 증가와 갈변현상이 일어났다. 살균 온도는
