Chlorella 첨가가 가공치즈 품질에 미치는 영향

국문 초록 (Abstract)

구형 단세포 녹조류이며 건강식품인 chlorella를 첨가하여 일반가공치즈의 기호도와 유사한 chlorella 가공치즈를 제조한 후 품질특성을 살펴보았다. 일반성분 및 pH는 전통적인 일반가공치즈의 정상적인 데이터로 안정성이 있는 품질특성을 나타내었다. 미생물은 모든 실험구에서 검출되지 않아 건강에 유해한 영향을 유발하지 않았다. 지방분리는 실험구간 품질차이가 발생하지 않았고 용융성은 chlorella 첨가량이 증가할수록 점진적으로 감소하였으나(p＜0.05) 모두 품질에 큰 영향을 미치지 않았다. 물성학적 특성은 hardness와 springiness가 유의적인(p＜0.05) 증가로 조직감 개선의 효과가 나타났다. 색도는 chlorella 고유의 색상인 녹황색으로 인해 모든 실험구가 대조구와 극히 유의하였다(p＜0.05). 관능검사 중 color 및 mouth feel은 대조구와 모든 실험구가 유의성(p＜0.05)이 있었으나 상품성 측면에서 CPC1이 적합하였다. 결과적으로 본 연구는 실험구 중 CPC1이 전통적인 일반가공치즈의 품질특성을 유지하며 기호성ㆍ상품성ㆍ시장성이 우수한 건강지향적인 chlorella 가공치즈의 개발 가능성을 제시하였다.

The effect of chlorella addition on the quality characteristics of processed cheese was investigated. Chlorella processed cheese was prepared in the different ratio of chlorella (0.5% (w/w) and 1.0% (w/w)). Chlorella processed cheese was stored at 10±1℃ and evaluated for the quality characteristics including general com-position, pH, the number of microorganisms, oiling off, meltability, rheological properties, color, and sensory evaluation. Contents of moisture, protein, fat, fat in dry matter, and pH values were not different from those of control cheese. Microorganisms were not detected. The degree of oiling off showed no significant difference, but meltability decreased significantly (p＜0.05). Hardness and springiness gradually increased significantly (p＜0.05), while cohesiveness gradually decreased significantly (p＜0.05). The L (lightness) values and the a (redness) values decreased with increasing chlorella contents, but the b (yellowness) values increased with increasing chlorella contents, so color expressed yellowish green. Compared to control cheese made by conventional way, QDA scores of color and mouthfeel of chlorella processed cheese were significantly higher (p＜0.05) and the most favorite quality characteristics were shown in the processed cheese with 0.5% (w/w) chlorella (CPC1). These results suggested that health?oriented chlorella processed cheese would be made by the addition of the chlorella.
