The present invention relates to a method of elimination of a biofilm using combined treatment and, more specifically, to a method for effectively eliminating biofilms formed on food and food-contact surfaces through UV-C/NaOCl treatment or UV-C/SAEW treatment. The method showed a significant biofilm reduction effect in case of combined treatment compared to single treatment. In particular, a more efficient biofilm reduction effect was confirmed in UV-C/SAEW combined treatment using SAEW, which has a lower chlorine concentration than NaOCl. In addition, the present invention provides the economical and industrially applicable biofilm removal method using easy-to-access UV-C, NaOCl, and SAEW treatment methods. 발명은 병용 처리를 이용한 바이오필름 제거 방법에 관한 것으로, 보다 상세하게 UV-C/NaOCl 처리 또는 UV-C/SAEW 처리를 통해 식품 및 식품과 접촉하는 표면에 형성된 바이오필름을 효과적으로 제거하는 방법에 관한 것으로, 병용처리시 단일처리한 것보다 유의미한 바이오필름 감소 효과를 나타내었으며, 특히, NaOCl보다 염소의 농도가 더 낮은 SAEW를 이용한 UV-C/SAEW 병용처리에서 더 효율적인 바이오필름 감소 효과를 확인하였다. 또한, 본 발명은 접근하기 쉬운 UV-C, NaOCl, 및 SAEW 처리방법을 이용하여 경제적이고 산업상 이용이 용이한 바이오필름 제거 방법을 제공한다.
