Abstract

The "Golden Sun" apricot (Prunus armeniaca L.) is prone to post-harvest softening, making it more susceptible to physical damage, diseases, and physiological disorders. This study investigated the impact of intense pulsed light (IPL) and modified atmosphere packaging (MAP) on texture softening in the "Golden Sun" apricot fruit by examining changes in cell wall pectin components. The results showed that the firmness of the IPL, MAP, and their synergistic treatment groups was 29 %, 46 %, and 70 % higher than that of the control group, which delayed the softening degree of the apricot fruit. The synergistic treatment primarily suppressed pectin-degrading enzyme activity, delayed pectin molecular weight degradation and side chain branching rate decline, inhibited the increase of water-soluble pectin (WSP) and ionic-soluble pectin (ISP) content, as well as the decrease of covalent-soluble pectin (CSP) content to maintain the integrity of the cell wall, thereby enhancing apricot fruit firmness. The results will provide valuable insights for inhibiting softening in apricot and other fruit through combining IPL with MAP.

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
