The Influence of Modified Atmosphere Packaging on Quality Properties of Kiwifruits During Cold Storage and Shelf Life

This study was carried out to evaulate the effects of different modified atmosphere packagings (MAPs) on quality characteristics of kiwifruit (Actinidia deliciosa cv. ‘Hayward’) during cold storage and shelf life. In the study, 4 different MAP were selected as Xtend, Aypek, Fresh and FreshPlus. Kiwifruit were stored at 0±0.5°C 90±5% RH during 180 days, and at 21°C, 70% RH for shelf life (5 days). MAP treatment significantly delayed weight loss of kiwifruit during cold storage. In all treatments firstly respiration rate increased, but it abruptly decreased after 60 days of cold storage and shelf life. With MAP treatment, L* value of skin color increased, whereas L* values of flesh decreased. Xtend and FreshPlus treatments retarded losses of fruit firmness. MAP treated-fruit has got higher the values of titratable acidity and vitamin C than control fruit. Results of study revealed that MAP treatments maintained fruit quality during cold storage and shelf life. But Aypek and Fresh MAP was more effective than other MAP treatments.
