Description

채소의 잔류 농약 제거방법{Method to remove pesticide residue from vegetables} Method to remove pesticide residue from vegetables}

본 발명은 채소의 잔류 농약 제거방법에 관한 것으로, 더욱 상세하게는 채소에 대한 농약 및 미생물 안전성에 효과적인 잔류 농약 제거방법에 관한 것이다.The present invention relates to a method for removing pesticide residues from vegetables, and more particularly, to a method for removing pesticide residues effective for the safety of pesticides and microorganisms for vegetables.

여기서는, 본 개시에 관한 배경기술이 제공되며, 이들이 반드시 공지기술을 의미하는 것은 아니다.BACKGROUND OF THE INVENTION Here, background art related to the present disclosure is provided, and they are not necessarily meant to be prior art.

경제성장에 따라 식생활에 있어서 유기농산물의 선호도 향상 및 농약 안전성에 많은 관심과 그에 따른 사회적 영향이 커져 가고 있으며, 신선하면서도 자연 성분이 그대로 보존된 식품을 선호하는 경향이 증가하고 있다. 그러나 구입 후 특별한 열처리나 조리과정 없이 생식으로 섭취되는 신선 농산물의 경우 미생물이나 농약 등의 안전성에 있어서 문제가 될 수 있다. In accordance with economic growth, a lot of interest in the improvement of preference for organic produce and the safety of pesticides in diet and the social impact thereof are growing, and the preference for fresh and preserved food with natural ingredients is increasing. However, in the case of fresh agricultural products that are consumed raw without special heat treatment or cooking after purchase, there may be a problem in the safety of microorganisms or pesticides.

최근 국내 유통되고 있는 과채류 12종, 총 289건에 대해 농약 잔류량을 분석한 결과 289건의 과채류 중 21.2%에서 잔류농약이 검출되었고, 5.2%가 잔류 농약 허용기준치를 초과하였으며, 부적합률이 높은 과채류는 깻잎, 상추, 시금치, 치커리 등의 순으로 나타났다. As a result of analyzing pesticide residues on a total of 289 cases of 12 types of fruits and vegetables currently circulating in Korea, residual pesticides were detected in 21.2% of 289 fruits and vegetables, and 5.2% exceeded the permitted standard for pesticide residues. Sesame leaves, lettuce, spinach, and chicory appeared in that order.

농약은 농산물의 생산증대를 위해 불가피하게 사용되는 농자재로 농약살포 중 발생하는 급성 독성 이외에도 농산물에 잔류하여 장기간에 걸친 섭취로 인체에 영향을 미치는 만성독성이 문제가 되고 있다. 또한 식품의 원료에 남아 있는 잔류 농약은 시간의 경과에 따라 소실될 뿐만 아니라 세척, 데치기, 가열 등의 과정으로 많은 양이 제거되는 것으로 알려져 있다. Pesticides are agricultural materials that are inevitably used to increase the production of agricultural products. In addition to acute toxicity generated during pesticide spraying, chronic toxicity that remains in agricultural products and affects the human body by long-term intake has become a problem. In addition, it is known that residual pesticides remaining in raw materials of food are not only lost over time, but also removed in large amounts through processes such as washing, blanching, and heating.
