This study was measured weight loss, total ascorbic acid, titratable acidity, soluble solids content and overall appearances to investigate the effect of corrugated fiberboard box coated with functional materials ; R, G, X box, R, G and X box and Con(double wall corrugated fiberboard) box during storage at 25℃. Weight loss of mandarin of control, corrugated paperboard box coated with functional materials(Y-, R-, G-box) after 8 days were 2.56% to 3.67%. There was not different to weight loss among the four kind of packages. Titratable acidity and soluble solids content of packages was not significant. Total ascorbic acid content(TAA) of mandarin packed with R-box and Y-box was 10% higher than that of control after 8 days. Decay ratio of R-box, Y-box, G-box and control was 4%, 10%, 10% and 8%, respectively. Overall appearance of R-box was the best.

제주산 감귤을 기존의 골판지와 이골판지에 특성이 다른 선도 유지기능성 소재 3종을 상자 내면에 코팅하여 여기에 감귤을 넣고 25℃에 8일간 저장하면서 선도 유지효과를 조사하였다. 중량은 모든 포장구에서 2.6-3.7%가 감소하였고 산도와 당도는 포장구간에 차가 없었으며 비타민 C 함량은 대조구 보다 R-Box와 Y-Box가 10% 높게 유지되고 있었다. 부패율도 R-Box는 4%였으나 나머지 포장구는 8-11%의 감귤이 부패되었으며 외관도 R-Box가 가장 양호하였다.
