Abstract

Edible sprouts are highly nutritious, containing numerous health-promoting phytochemicals and nutrients. However, the process of sprouting is subject to potential contamination by microorganisms attached to the seed coat. The objective of this study was to determine the effects of air anions generated by spray ionization on growth and sterilization of edible sprouts. Treatment with air anions has positive effects on plant growth and sterilization in 4 kinds of sprouts. Hypocotyl length in red cabbage and kale increased approximately 1.26-fold and radicle length of lettuce, red cabbage, and kale increased 1.4 to 1.6-fold compared to the control. The fresh weight of sprouts in the spray-ionization treatment was significantly (16.0-38.5%) higher than that of the controls. Radicle activity in sprouts exposed to anions was higher than that of the control in all species. Bacterial counts on lettuce, red cabbage, and tatsoi decreased significantly (by 41%, 66%, and 19%, respectively), and bacterial colonies also declined in drainage water. Our findings suggest that spray-ionization treatment is useful for improving sprout growth and for sterilizing sprouts.

새싹은 영양분이 풍부한 식품이다. 하지만 생산 과정에서 종피에 있는 미생물에 의한 오염 가능성이 존재한다. 이 실험의 목적은 음이온 처리가 새싹의 생장과 살균에 미치는 효과를 구명하는 것이다. 음이온 처리는 4종류 의 새싹의 생장과 살균효과에 긍정적인 효과를 보였다. 대조구에 비해 음이온 처리한 적양배추와 케일 새싹의 배축길이는 약 1.26배 증가하였으며, 상추, 적양배추, 케일 유근의 길이는 1.4~1.6배 증가하였다. 모든 새싹의 생체중은 음이온 처리했을 때 대조구에 비해 16.0~38.5% 유의적으로 증가하였다. 유근의 활력 또한 음이온 처 리가 대조구에 비해 유의적으로 높은 수치를 보였다. 음이온 처리된 상추, 적양배추, 다채 새싹의 일반 세균 수는 대조구에 비해 각각 41%, 66%, 19% 감소하였으며, 배수되는 물의 세균 수 또한 감소되었다. 결국 음이 온처리는 새싹의 생장을 향상시켰으며, 동시에 살균하는데도 효과적이었다.
