Background: In recent years, many studies have been carried out to improve the
phytochemical characteristics and increase the life after harvest of horticultural
products, especially short-lived products, and many solutions and methods are used
to maintain product quality and reduce post-harvest losses. In the meantime, fruits
such as strawberries, in addition to nutritional aspects, have a much higher
medicinal value, which requires special attention from harvesting.
Aim: Due to the growing concern of the general public and nutritional scientists
about the adverse effects of chemical preservatives, the need to pay more attention
to the use of natural materials to preserve agricultural products is felt more and
more. Therefore, this study was designed and implemented in order to investigate
the effect of pecan seed extract and seaweed on increasing the storage life and
maintaining the quality of Camarosa strawberry fruit during 12 days of storage.
Methodology: The experiment was conducted as a factorial in the form of a
completely random design in the laboratory of the Department of Horticultural
Sciences, Faculty of Agriculture and Natural Resources, Persian Gulf University.
Treating fruits with seaweed in two concentrations (5 and 10 g/liter), pecan in two
concentrations (10 and 20 g/liter) and the interaction between pecan and algae
compared to untreated fruits (as a control) each was immersed for 10 seconds. Some
fruit characteristics, including percentage of decay, firmness of fruit tissue, vitamin
C, total soluble solids (TSS), titratable acidity (TA), flavor index, anthocyanin and
pH of fruit juice at 0, 6 and 12 days of storage. It was taken.
findings: Based on the results, with the passage of storage time, traits such as
vitamin C, TA, texture firmness, taste index and anthocyanin decreased, and the
traits of decay percentage, TSS and pH of fruit juice showed an increasing trend.
The lowest percentage of decay was observed in the treatments of algae 5 g/l a
