Abstract

Objectives: This study was conducted to analyze the sugar content, acidity, and viscosity of the Korean frozen desert. Methods: A total of 60 types of frozen desserts marketed in Korea were randomly selected and classified into frozen desserts, milk-fat ice cream group, and non-fat ice cream group according to the classification criteria for frozen desserts. Each product was treated under the same conditions to investigate the component of each product, and sugar content, acidity, and viscosity were measured. Frequency analysis and one-way ANOVA were performed. Results: As a result of analyzing the characteristics related to dental caries activity by group, the frozen dessert had the lowest average pH of 3.67, and the sugar content was significantly higher in the milk-fat group (33.22) and non-fat group (32.89) than in the frozen dessert. The viscosity was also the highest in the milk-fat group at 32.62, and the frozen dessert was significantly lower at 9.42. Conclusions: Due to the abnormal temperature and spread of the coronavirus, consumption of frozen desserts at home is on the rise. To prevent dental caries in children, education is needed for children and their guardians for proper oral care after eating frozen desserts.

연구목적: 본 연구는 아동의 치아우식증 발생에 영향을 줄 수 있는 빙과류를 종류에 따라 구분하고, 당도와 산도, 비점조도를 조사하여 분석하고자 시행하였다. 연구방법: 국내에서 생산 및 시판되는 빙과류 60종을 무작위로 선택하여 빙과류 분류 기준에 따라 빙과, 유지방군아이스크림, 비유지방군아이스크림으로 구분하였다. 각 제품을 동일한 조건으로 처리하여 제품별 성분함량을 조사하였으며, 당도와 산도, 점조도를 측정하였고 비점조도를 계산하였다. 대상 빙과류의 일반적인 특성은 빈도분석을 시행하였고, 식품 유형에 따른 빙과류의 영양성분의 차이와 치아우식 관련 특성의 차이는 일원배치 분산분석을 수행하였다. 유의수준(α)은 0.05로 하였다. 연구결과: 조사 대상 빙과류는 총 60개로 빙과, 유지방군, 비유지방군 각각 20개씩이었다. 품목별 영양성분에서 나트륨은 비유지방군이 59.94 mg으로 가장 높았고 빙과는 평균 15.94 mg으로 유의하게 낮았다. 지방 함량은 유지방군이 7.07 g으로 가장 높았다. 치아우식 활성도 관련 특성을 각 제품군에 따라 분석한 결과 pH는 빙과가 평균 3.67로 가장 낮았으며, 당도는 유지방군(33.22)과 비유지방군(32.89)이 빙과보다 유의하게 높았다. 비점조도 또한 유지방군이 32.62로 가장 높았고, 빙과는 9.42로 유의하게 낮았다. 결론: 이상 기온 현상과 코로나바이러스 확산으로 인하여 가정 내 빙과류 섭취가 증가하는 추세이다. 가정 내에서 아동의 치아우식증 발생을 예방하기 위하여 빙과류 섭취 후 적절한 구강 관리를 할 수 있도록 아동과 보호자 대상의 교육이 필요하다.
