Abstract

This study evaluated the effect of steam heating, gamma irradiation, and ultraviolet (UV) irradiation on microorganism reduction in order to determine an effective sterilization method for red pepper powder. The effect of each treatment on the reduction of thermoduric bacteria and total aerobic bacteria in red pepper powder were as follows: 10 kGy gamma irradiation, reduction of 4 log and 6 log CFU/g, respectively; 12 mW/㎠ UV irradiation (264 nm UV-C), reduction of less than 1 log CFU/g; steam heating at 120℃ for 40 s, reduction of approximately 2 log CFU/g. High-temperature short-time processing at 110℃ for 30 s reduced the total bacterial count in Gochujang solution from 5.70 log CFU/g to 2.26 log CFU/g; at 121℃, the solution was commercially sterile. Steam heating resulted in 1, 2, and 4 log microbial inactivation in garlic, onion, and pepper powder, respectively. Steam sterilization, which consumers prefer over other methods, may be an effective method for reducing microorganisms in spice powders, including those in red pepper powder.

본 연구에서는 위생적인 고춧가루 및 고추장 소스의 효과적인 살균방법을 확립하기 위한 기반 연구로서 감마선, 자외선 조사를 이용한 비가열 살균 및 스팀을 이용한 직,간접 가열살균에 의한 미생물 저감화 효과에 대한 세부 고찰을 실시하였다. 실험 결과 호기성 총균 및 내열성균이 10 kGy 선량 감마선 조사에서는 각각 5-6 log CFU/g, 방사조도 12 mW/㎠ 자외선 조사는 1 log CFU/g 내외, 그리고 120℃, 40 s 스팀가열 살균시는 2 log CFU/g 내외의 감균 효과를 나타내었다. 스팀 가열살균 방법은 감마선 조사 대비 사멸효과는 떨어지지만 2 log CFU/g의 유효적인(p<0.05) 미생물 저감화 효과를 나타내므로 가열온도 및 처리시간 등의 살균공정 조건을 최적화하면 살균효과, 상업적 설비, 처리비용 및 소비자 선호도 등을 종합 검토시 색상 품질 손상 없이 효과적으로 고춧가루내 바실루스 계통의 내열성균을 제어할 수 있는 방법으로 사료된다. 또한 120℃ 스팀 순간 가열살균시 흑후추 분말은 4 log CFU/g, 양파 분말은 2 log CFU/g, 그리고 마늘 분말은 1 log CFU/g 내외의 호기성 총균이 감소하여 다양한 향신야채 건조분말의 미생물 제어에도 유효한 방법으로 판명되었다. 그리고 고추장 용액 경우도 고온 순간 가열방식인 HTST 적용시 110℃에서 부터 호기성 총균수가 무처리 5 log CFU/g에서 2.26 CFU/g로 효과적으로 감소하기 시작하여, 121℃ 처리에서는 상업적 멸균상태로 나타나 고춧가루 및 고추장을 함유한 매운맛 소스의 효과적인 살균방법으로 판명되었다.
