Improving Shelf Life of Strawberry Through Application of Sodium Alginate and Ascorbic Acid Coatings
In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination with AA (1% w/v) and the storage periods (7 and 14 days). The results showed that lightness (L*), chroma, firmness, total acidity, vitamin C, phenols, and antioxidant activity decreased during storage, but coating improved them in the sold-stored strwberries. SA2%+AA1% coating was the best treatment in maintaining the fruit quality. Firmness, weight loss, fruit L*, fruit chroma, sepal L*, sepal chroma, total phenolics, and polyphenol oxidase activity were decreased by 15%, 1.95%, 16.7%, 2.66%, 10.23%, 16%, 19.47% and 2.5%, respectively for SA2%+AA1% samples at the end of the 14th day, which was lower than the untreated fruits. The results suggested that postharvest application of SA2%+AA1% has the potential to extend the storage life of strawberry fruits by reducing water loss and maintaining fruit quality.
Effect of Ascorbic Acid and Essential Oil of Thymbra spicata on Shelf Life and Quality Maintenance of Strawberry
Aiming at finding a suitable treatment for maintaining the fruit quality and increase the shelf life of strawberry, effects of ascorbic acid and essential oil of Thymbra spicata were evaluated. Fruits were dipped in 10 and 15 mM of ascorbic acid and essential oil of T. spicata (400 and 600 ppm) for two minutes, and after drying at room temperature, were packed by cellophane in the polyethylene ...متن کامل

application of carboxymethyl cellulose based coatings containing oleic acid and antimicrobial compounds for improving quality and extending shelf-life of egg
during storage of eggs, unfavorable changes occur due to exertion of co2 and water vapor from through of crust pinholes. one of the practical methods for preventing or reducing these changes is to use biopolymer-based coatings. in this research, five coating solutions based on carboxymethyl cellulose (cmc) and glycerol as plasticizer, oleic acid (1 and 2% v/v) and antimicrobial agents (potassiu...متن کامل
