초록
LED(light emiting diode)를 가정용 냉장고에 부착하여 양배추의 선도 유지에 미치는 영향을 조사하였다. 가정용 냉장고에 부착된 LED의 조사가 저장 중 양배추의 품질 변화에 미치는 가장 큰 효과는 엽록소 합성, 비타민 C 및 페놀성분의 함량 증가였다. LED가 부착된 냉장고에 저장된 양배추는 절단면이 흰색에서 녹색으로 변화하였으며,
Abstract
A LED (light emitting diode) was attached inside the cold (4℃) compartment of a home refrigerator to investigate a possible effect on freshness prolongation of cabbage over 10 d of storage. The LED increased chlorophyll synthesis, inhibited vitamin C degradation, and increased the content of phenolics, compared to values measured in cabbages stored in an identical refrigerator without the LED. In the refrigerator with the LED, the color of cabbage leaves remained green for a period fourfold longer than that seen in a conventional refrigerator. Vitamin C content was twice that of a conventionally stored cabbage, and phenolic content was 14% higher in the LED-illuminated vegetables.
