Abstract

This study was conducted to develop an appropriated management for safety of children snacks sold around school. Total 598 items as targeted food were collected; 66 biscuits, 320 candies, 57 chocolates, 40 ice creams and 115 beverages. Microbiological hazards such as total aerobic bacteria, Coliforms, Escherichia coli, Bacillus ceruse, Yeasts & molds were measured by analytical method in Korean food code. Total aerobic bacteria and Yeasts & molds were detected in cookies at the level of less than 2.69 and 2.65 $log_{10}$ CFU/g and the detection rates were 54.55 and 62.12%, respectively. Bacillus cereus was detected in 1 snack only at the level of 1.39 $log_{10}$ CFU/g but it was less than Korean microbial standards and specifications (3 $log_{10}$ CFU/g). Total aerobic bacteria and Yeasts & molds were detected in candies less than 2.86, 3.36 $log_{10}$ CFU/g and the detection rates were 46,8% respectively. Total aerobic bacteria, Yeast & mold were detected in chocolates at the levels less than 2.52 and 1.87 $log_{10}$ CFU/g and the detection rates were 33 and 22% respectively. Total aerobic bacteria in both ice creams and beverages were detected at the levels less than 3.39 and 1.35 $log_{10}$ CFU/g and the detection rates were 82 and 5% respectively. Coliforms were found in one ice cream (1.39 $log_{10}$ CFU/g) only. The result of this study indicated that all children snacks around school were suitable for microbial standard and specifications in Korean Food Code. However, since most children snacks around school are circulated without proper storage temperature and handing condition, consistent microbial management for children snacks are needed.

본 연구는 학교 주변에서 판매되고 있는 어린이기호식품의 정확한 실태 파악과 위해분석을 통하여 어린이 기호식품의 적절한 관리방안을 마련하기 위해 수행되었다. 현재 학교 주변에서 판매되고 있는 과자류, 캔디류, 초콜릿류, 빙과류, 음료류의 어린이기호식품 총 598종을 구매하여 시료로 사용하였으며, 미생물학적 위해요소(일반세균, 진균, 대장균군, 대장균, Bacillus cereus)에 대해 식품공전법을 사용하여 분석하였다. 과자류는 일반세균, 진균이 각각 2.69, 2.65 $log_{10}$ CFU/g 이하 수준으로 검출되었고 검출율은 각각 54.55, 62.12%이었다. 파자 1개 제품에서 Bacillus cereus가 검출되었으나(1.39 $log_{10}$ CFU/g), 법적 허용기준(3 log) 이하였다. 캔디류는 일반세균, 진균이 각각 최대 2.86, 3.36$log_{10}$ CFU/g 검출되었고 검출율은 각각 46, 8%였다. 초콜릿류는 일반세균, 진균이 각각 최대 2.52, 1.87 $log_{10}$ CFU/g 검출 되었고, 검출율은 각각 33, 22%로 나타났다. 빙과류와 음료류는 일반세균이 각각 최대 3.39, 1.35 log10CFU/mL 검출되었고, 검출율은 각각 82, 5%였으며, 빙과류 1개 제품에서 대장균군이 1.00 $log_{10}$ CFU/mL 수준으로 검출되었다. 본 연구결과, 시판되는 모든 어린이 기호식품이 미생물기준에 적합한 것으로 나타났다. 그러나 대부분의 학교 주변 어린이기호식품 판매점이 보관 온도나 취급조건 등을 갖추지 못한 채 제품이 유통, 판매되어지기 때문에 어린이기호식품에 대한 지속적인 미생물 관리가 필요할 것으로 판단된다.
