개발한 EPS 포장상자가 사과의 신선도 유지효과 기능이 있는지의 여부를 조사코자 사과를 포장하여 2에 저장하면서 골판지상자와 0.02와 0.04mm 두께의 LDPE필름, 기능성 MA필름과 50배로 발로시킨 EPS 상자에 사과를 15kg씩 포장하며 포장재간의 신선도 유지 효과를 비교하였다. 저장 40일 후 중량감소는 대조구는 5.7 %, EPS 상자는 0.5%의 중량감소가 나타났고, 비타민C도 2.06과 2.31mg%로 EPS 포장구가 높게 유지되

This study was measured weight loss, total ascorbic acid, titratable acidity, and soluble solids content to investigate the effect of EPS(expanded polystyrene foam, foaming rate 55 times V/W) box, LDPE film pouches and double wall corrugated fiberboard box during storage at 20. Weight loss of apple packed with corrugated paperboard box after 40 days storage was 5.7%, arid those of LDPE, CE(zeolited coated film) film and EPS box were 0.2-0.5%. Ascorbic acid content of apple packed with LDPE, CE, EPS was higher than that of control. Titratable acidity and total soluble solid content of control were changed 40% and 10%, but the EPS were changed 27% and 4%, respectively. Overall appearances of ‘Fuji’apple packed with LDPE, CE and EPS were better than that of control.
