초록
감마선을 이용하여 미생물학적으로 안전하면서 관능적 품질이 우수한 아이스크림을 개발하기 위해 감마선에 안정적인 spearmint, mint 및 citrus향을 선발하고 이를 이용하여 감마선 조사에 의한 특유의 냄새변화가 없는 아이스크림을 제조한 후 품질을 비교하였다. 일반적인 조성은 향 무첨가 대조구와 처리구 사이에 차이가 없었으며, 총균수는 향 무첨가 대조구, spearmint, mint 및 citrus향 첨가구가 각각 2.38, 1.23, 1.38 및 1.15 log CFU/g 수준에서 검출되었다. 그러나 대조구는 3 kGy, 그 외 처리구는 1 kGy 선량에서 균이 검출되지 않았다. 관능검사 결과 mint향을 첨가하고 1 kGy 감마선 처리한 아이스크림과 citrus향을 첨가하고 3 kGy에서 감마선 처리한 아이스크림이 유의적으로 높은 기호도를 보였다. 따라서 3 kGy 이하의 감마선 조사와 mint 또는 citrus향의 선택적 첨가는 관능적으로 문제가 없으면서 유아, 노약자, 환자 등 민감한 소비자들에 대한 미생물학적 안전성을 확보하는 기술로 사용될 수 있을 것으로 판단된다.
Abstract
To develop the manufacturing method of ice cream with microbiologically safe and proper sensory quality using irradiation for sensitive consumer, 3 different flavors, which were resistant to their flavors against irradiation, were selected and used for ice cream manufacturing to reduce the irradiation-induced off-flavor problem. The general composition was not different among treatments. Total aerobic bacteria were detected as 2.38, 1.23, 1.38, and 1.15 log CFU/g level in ice cream with control(no flavor added), spearmint, mint, and citrus flavor, respectively. No viable cells were observed by irradiation at 1 kGy except for the control. Sensory evaluation indicated that the irradiated ice cream with spearmint flavor at 1 kGy and citrus flavor at 3 kGy had higher overall acceptability. Therefore, a low dose irradiation (less than 3 kGy) with mint or citrus flavors may enhance the safety of ice cream with proper sensory quality for sensitive consumer.
