In order to preserve the quality of apple fruit, it is crucial to choose the most suitable storage technology. Nevertheless, it is also important to maintain the quality of apples during the shelf life period. In this study, changes in various biochemical quality parameters of ‘Golden Delicious’ and ‘Idared’ apples during a prolonged shelf life period, after conventional normal atmosphere (NA) and ultra-low oxygen (ULO) storage, were investigated. After the harvest, the fruit of examined cultivars were stored in two atmospheres for six months. Weight loss, changes in content of sugars, organic acids, total phenols, total flavonoids, pectic fractions, and antioxidant capacity were monitored. Samples were evaluated immediately after removal from the cold chambers and after 10 and 20 days of shelf life at 20 °C. ‘Golden Delicious’ apples stored in ULO exhibited better qualitative characteristics during 20 days of shelf life compared with apples of the same cultivar stored in NA. However, evaluated traits in ‘Idared’ apples from NA chambers were of higher quality in comparison with ‘Idared’ apples stored in the ULO atmosphere.

The introduction of new varieties in fruit production should consider consumer attitudes regarding the appearance and taste of the fruits. In order to evaluate the consumer attitudes in Serbia and Bosnia & Herzegovina (B&H), on the most important characteristics of cherry fruits, an online survey was conducted with 402 respondents. Participation in the survey was taken by 53.23% of respondents from Serbia and 46.77% from B&H, most of which were women (54.23%). Consumers expressed their views on the most important external (fruit colour, fruit shape, fruit size, presence of a stalk on the fruit, length of the stalk and the presence of damage to the fruit) and internal (fruit taste, fruit firmness) characteristics of the fruit. According to the results, the attitude toward the fruit size, the presence of a stalk and the stalk length, as well as fruit firmness was dependent upon respondents’ residence. Both male and female respondents had similar attitudes toward the cherry characteristics except for the fruit taste and the most important cherry characteristics. The age of a respondent influenced the attitude toward the fruit size and the presence of a stalk, as well as the fruit firmness.
