생홍고추 및 생홍피망의 장기저장 방법으로 HDPE 및 LDPE포장내에 시료와 함께 서로 다른 양의 NaCl을 삽입함으로써 MA저장 효과를 조사하였다. HDPE 및 LDPE 포장내의 NaCl 함량은 0 g, 15 g, 20 g, 25 g이었으며, 대조구로 무포장이 사용되었다. 홍고추 및 홍피망의 각각 50일 및 35일간 MA저장 동안 주기적으로 중량 변화와 곰팡이 발생율을 조사하였고, 저장 초기와 말기에는 색도와 경도를 측정·비교하였다. NaCl을
The effects of modified atmosphere(MA) storage for fresh red chili pepper and red bell pepper fruits were investigated with storing in polyethylene film with various fine holes. During the storage of the both pepper fruits, the weight loss, color change, mold emergence, and firmness were evaluated. The weight loss of pepper fruits packaged without holes on film was less than 3%, even though it was each 50% and 25% for non packaged red chili pepper and red bell pepper fruits. The rates of mold emergence of red chili pepper and red bell pepper fruits were reached to each 60% and 50% at the end of storage period as stored in film without holes. However, the rate of mold emergence of pepper fruits was lowered when fruits were stored in MA with low relative humidity (70∼80%). The color and firmness of pepper fruits were not much changed when fruits were stored in MA with high humidity.
In order to extend the shelf-life of red chili pepper, MA and CA technology were used. In MA storage, red chili peppers(Jinmi and Jangkun) were packaged in 0.03 mm PE film bags(3 kg/bag) having two holes(2~3 cm) at 2~3C or 7~8C. In CA storage, red chili peppers(Jinmi) were stored on following gas composition; 5 or 10% CO in combination with 2 or 5% O at 2~3C, respectively. The changes of weight loss and decay rates during MA storage were less in Jinmi than in Jangkun and less at 2~3C storage(except O 5%, CO 10% condition) while in CA it decreased after 40 days of storage. Red chili peppers would be stored for 30 days when stored in MA conditions(0.03 mm PE film bag) and for 60 days when srored in CA condition on O 2%, CO 10% based on overall quality of sensory evaluation.
