Abstract
In this study, sodium alginate (SA) treatments (0, 0.5, 1, and 1.5%) were employed to maintaining the nutritional value of apricot in cold (2 ± 0.5 °C) storage periods (0, 8, 16, and 24 days). According to the findings, the control sample exhibited maximum weight loss until the 24th day. All SA concentrations had a positive effect on maintaining fruit weight and firmness. Maximum values of total acids, vitamin C, and taste in the final stage were observed in the SA 1%. The SA treatment had the highest antioxidant activity in all periods of storage. Unlike phenol, antioxidant activity, and vitamin C, there was an increase in flavonoid content during storage. Although the highest flavonoid content registered in control sample. All SA treatments increased the peroxidase and polyphenol oxidase activity, while maintaining flavor and aroma compared to the control. Even though the nutritional value of apricots treated with SA was high, we observed SA 1% has more acceptance from the consumer's point of view in the final storage period.
