Abstract:
... MAIN CONCLUSION: The higher water loss of russeted fruit results from the higher permeance of the periderm of the russeted skin as compared to that of the intact cuticle and epidermis. Apple fruit surfaces are often in-parallel composites, comprising areas of intact cuticle (atop a healthy epidermis) adjacent to areas covered by periderm (so-called russet). The occurrence of non-russeting and russ ...

Abstract:
... Browning control in apple juice has been one of the highest challenges within food technology. High pressure processing (HPP) ensures quality and safety in apple juice during its shelf life, but enzymatic browning may be increased. Hence, the effects of addition of α- (10/30/40 mM) and β-cyclodextrins (CDs) (5/10/15 mM) during apple juicing and HPP treatment (0/300/400/500 MPa; 5 min, 22 °C) were ...

Abstract:
... In the present study, the properties of two apple sourced-pectin (AP-1 and AP-2) were comparative studied, and their influence on the formation of high internal-phase Pickering emulsions (HIPPEs) was investigated. Results showed that AP-2 has lower polydispersity index (PDI = 2.51) than AP-1. Zein/AP-2 complex nanoparticles (ZAPs-2) was able to stabilize 80% oil-phase to form HIPPEs, while ZAPs-1 ...

Abstract:
... Birds are common pests in fruit orchards. They frequently consume and damage fruit resulting in decreased yields for growers. The true extent of damage is difficult to measure. Producer surveys are often implemented to estimate damage, but the accuracy of these estimates is uncertain. We compared damage estimates obtained through field studies with estimates from a producer survey for three fruit ...

Abstract:
... In the absence of protein-coding ability, viroid RNAs rely on direct interactions with host factors for their infectivity. RNA structural elements are likely involved in these interactions. Therefore, preservation of a structural element, despite the sequence variability existing between the variants of a viroid population, is considered a solid evidence of its relevant role in vivo. In this study ...

In most of the apple growing areas freezing temperatures may occur in the flowering period, so it is important to study the frost tolerance of cultivars not only during dormancy but during the flowering period as well. Frost tolerance can be assessed by several methods, but the most accurate results can be achieved by artificial freezing experiments. The results of frost resistance tests performed ...
