Abstract

The effect of packaging materials on the quality and physiological activity of Angelica acutiloba leaves during storage at $4^{\circ}C$ for 20 days and after being transferred to room temperature for 2 days was studied. The experiment was conducted using three packaging materials: the corrugated box (control); corrugated box with $20{\mu}m$ HDPE perforated film liner; and corrugated box with paraffin wax coated paper $+20{\mu}m$ HDPE perforated film liner. Changes in weight, color, aroma, overall visual quality, antioxidant activity, and total flavonoids were investigated. Based on the result, the treatments using corrugated box with $20{\mu}m$ HDPE perforated film liner and the corrugated box with paraffin wax coated paper $+20{\mu}m$ HDPE perforated film liner, were effective in minimizing weight loss, and maintaining external color and overall quality as compared to corrugated box only (control). The corrugated box with paraffin wax coated paper $+20{\mu}m$ HDPE perforated film liner was more effective in maintaining antioxidant activity and total flavonoids than other treatments. Prolonging the freshness using corrugated box with paraffin wax coated paper $+20{\mu}m$ HDPE perforated film liner could increase the marketability of Angelica acutiloba leaves in the domestic market.

본 연구는 유통현장에서 다양한 포장 형태로 이용되는 일당 귀 잎의 포장방법별 선도유지 효과를 구명하고자 하였다. 현장에서 이용되는 일당귀 잎의 1 kg 단위로 포장 형태를 골판지상자에 바로 일당귀 잎을 포장한 무처리를 대조구로 하여 $20{\mu}m$ HDPE 천공 필름, $20{\mu}m$ HDPE 천공 필름+파라핀왁스 코팅 종이와 같이 3가지로 분류하였다. $4^{\circ}C$ 저온에서 20일간 저장하고 20일 후 상온으로 옮겨 2일간 추가 유통하면서 중량감소율, 색도, 외관품위, 항산화활성과 총 플라보노이드 함량 변화를 조사하였다. 그 결과, 포장 형태에 따른 일당귀 잎의 중량 감소는 봉지 형태의 $20{\mu}m$ HDPE 천공 필름 포장과 $20{\mu}m$ HDPE 천공 필름+파라핀왁스 코팅 종이 포장에 의해 가장 적었으며 저장 중의 엽색, 외관 및 중량의 변화폭도 적어 상품성이 20일간 유지되었다. 대조구로 사용한 일반 골판지상자에 포장한 일당귀 잎은 저장 15일 째 상품성을 상실하였다. 항산화활성과 총 플라보노이드 함량은 $4^{\circ}C$에 20일간 저온저장 및 상온에 2일간 추가 유통하는 동안 $20{\mu}m$ HDPE 천공 필름+파라핀왁스 코팅종이 처리가 다른 처리에 비하여 높게 유지되어 생리활성 물질 함량 보존에 유효하였으며, 국내 유통현장에서 사용하기에 가장 적절한 포장방법으로 나타났다.
