  • Effect of several PLA films on strawberry packaging was investigated. Three types of PLA film (non-perforated PLA1, perforated films of PLA2 and PLA3) were used for packing strawberry and the fruit quality was measured during 6 day storage at 10. For comparison, two types of OPP/PE film (non-perforated OPP1 and perforated OPP2) were used for strawberry packaging. Weight loss of all the treatments was below 0.12% after 6 day, seeming to be in tolerable range. PLA3 package showed the best retention in fruit firmness, PLA2 and PLA3 packages the least changes in acidity, and PLA2 package gave the least changes of soluble solid content and vitamin C content. There have been no differences in surface color among packages. Perforated PLA films could be effective for use as packaging of strawberry.

  • 포장재별로 처리한 콩나물의 저장 중 품질변화를 살펴보았다. 중량 감소율은 OPP필름에 비해 PLA 필름이 더 높은 것으로 나타났으나 0.025% 이하의 감소율로 큰 차이를 보이진 않았다. 수분함량의 경우 P3 포장구가 다른 처리구 보다 가장 적은 감소율을 보였으며, 총균수 변화에서는 P2, P3 포장구가 가장 적은 증가율을 나타내었으며, 외관상태에서 OPP 포장구는 봉투 개봉시 모든 포장구에서 부패취가 발생하였다. 비타민C 함량 변화는 PLA2 포장구가 변화율이 적었으며, PLA3 필름구가 그 다음으로 나타났으며, 기호도 조사에서는 PLA2 포장구가 모든 항목에서 높은 점수를 나타냈다. 결과적으로 OPP 포장구 보다는 PLA 포장구의 변화가 적었음을 알 수 있었으며, 그 중PLA2와 PLA3 필름이 콩나물 저장에 가장 효과적임을 알 수 있었다.

  • The shelf-life of fresh mushrooms is notably limited because their browning, texture change, and decay are too fast after immediately harvest. Especially, the best management for extending golden needle mushroom's shelf-life is modified atmosphere packaging under pressure vacuum at cold storage. In this study, three types of films, $20{\mu}m$ polyethylene+polypropylene (PE+PP), oriented polypropylene (OPP), and low density polyethylene (LDPE) were tested to extend the shelf-life of golden needle mushrooms. Mushrooms were packed under pressure vacuum and stored at $10^{\circ}C$ for 2 weeks. The golden mushrooms in LDPE film as a commercial packaging, were highly perishable and immediately proceed deterioration as browning, elongation, fluctuation of respiratory quotient (RQ) and softening within 7 days after packaging. On the other hand, the mushrooms in OPP and PE+PP film shown that shelf-life were extend to 14 days from 7 days, causing delay breakup of vacuum and maintenance of color, length, and RQ during storage. The breakup of vacuum in PE+PP film was faster few days than OPP film packaging. This present study indicated that the golden needle mushrooms by OPP packaging under pressure vacuum treatment might be extended the shelf-life until approximately 14 days during cold storage.
