Abstract:
본 발명은 세균 특이적 항체 지시계와 QR코드 및/또는 바코드를 포함하는 식품 포장 키트 및 이를 이용하여 식품의 세균 오염 여부를 현장에서 식별할 수 있는 기술에 관한 것이다. 본 발명의 식품 포장 키트를 이용하여 유통된 식품의 식중독균에 의한 오염 여부를 소비자가 구매 현장에서 식별할 수 있다. 또한, 본 발명의 식품 검사 시스템에 의하여 식품의 대량 유통 단계에서도 식품의 식중독균에 의한 오염 여부를 간편하고 신속하게 검출할 수 있다.
Abstract:
PURPOSE: A food packaging kit for the detection of bacteria is provided to rapidly and easily detect contamination due to food poisoning bacteria of food in a bulk distribution stage of the food. CONSTITUTION: A food packaging kit for the detection of bacteria includes a bacteria specific antibody indicator and a quick response code and/or a bar code. The bacteria are gram-positive bacteria or gram negative bacteria. The antibody Indicator is an exotoxin specific antibody Indicator of the gram-positive bacteria or an LPS specific antibody Indicator of the gram-negative bacteria. The exotoxin is enterotoxin. A color of the quick response code and/or the bar code is changed by an antigen which is detected through the antibody indicator.

Abstract:
PURPOSE: A natural food preservative is provided to minimize the generation of problems caused by the toxicity and irritation effect of a chlorine based chemical preservative. CONSTITUTION: A natural food preservative contains 1-2 parts of paeonia lactiflora extract by weight, 1-2 parts of cinnamomum loureirii extract by weight, and 3-8 parts of rhus japonica extract by weight. The extracts are obtained by the following steps: heat-extracting paeonia lactiflora, cinnamomum loureirii, and rhus japonica extract at 50-90 deg C for 30-200 minutes after mixing with solvents, separately; decompress-concentrating each extract at 20-80 deg C for 60-200 minutes; and freeze-drying the obtained concentrate.
