고분자 키토산 처리가 딸기 과실의 품질과 부패에 미치는 영향 = Effect of High Molecular Weight Chitosan on the Quality and Decay of Strawberry Fruits

다국어 초록 (Multilingual Abstract)

This study was aimed to determine the effect of high molecular weight chitosan treatment on the decay incidence and fruit quality in strawberries. Preharvest spray of chitosan (0.2%) effectively reduced the incidence of grey mould and increased fruit firmness. Chitosan application was also effective on remaining of surface gloss. This is probably due to coating effect. Physiological disorders were not found in treatment of 4 sprays. Internal quality such as soluble solid content and acidity seemed not to be affected by chitosan application. The effect of chitosan on keeping freshness was clear in fruit without physical damage at harvest, but muck less effective in injured fruit. Postharvest application of chitosan did not affect fruit quality. Above results indicated that chitosan is an alternative to keep strawberry quality through delaying decay and keeping firmness.
