Abstract:

An understanding of biochemical events of cold storage may lead to more effective methods of preventing apple fruits from ripening and keeping their quality. This study aimed at determining the level of reduced and oxidized forms of ascorbic acid, and the activity of ascorbate peroxidase, catalase, and superoxide dismutase enzymes changes in pulp of Golden delicious apple cultivar during cold storage. Apples were kept in common cold storage condition (1 oC, 95% - 97% RH) for 135 days for subsequent analysis.During cold storage condition, no significant changes were observed in the content of reduced and oxidized forms of ascorbic acid. However, levels of total flavonoids declined as storage time progressed. Superoxide dismutase and ascorbate peroxidase activities were decreased while the activity of catalase was increased.

Screening for antioxidant and antibacterial activities of phenolics from Golden Delicious apple pomace

BACKGROUND Synthetic antioxidants and antimicrobials are losing ground to their natural counterparts and therefore, the food industry has motivated to seek other natural alternatives. Apple pomace, a by-product in the processing of apples, is rich in polyphenols, and plant polyphenols have been used as food additives owing to their strong antioxidant and antimicrobial properties. The goal of th...

Physiological Responses of Some Rootstocks and Interspecific Hybrids of Pistachio to Cold Stress under Greenhouse Conditions

Cold is an environmental factor limiting the growth and yield of agricultural crops. To find cold-tolerant pistachio rootstocks, a factorial experiment was conducted at Pistachio Research Center (PRC), Rafsanjan, Iran during 2017-2018. The factors included six rootstocks (Badami Zarand, Ghazvini, Sarakhs, Integerrima × Badami Zarand, Integerrima × Ghazvini and Integerrima × Sarakhs) and four th...
