This study was conducted to investigate the effects of combined treatment of sodium alginate and ascorbic acid on the shelf life of strawberry fruits stored at 4±1 ° C. The treatments included control (distilled water), ascorbic acid (1%) with sodium alginate (1, 2 and 3%) and storage period for 7 and 14 days with 4 replicates. During storage, brightness index, chroma index, firmness, total acidity, vitamin C, phenol content, antioxidant activity and anthocyanin content were decreased, but the application of coatings preserved these indices as alginate 2% + ascorbic acid 1% was more effective to preserve these traits during storage. During storage period, polyphenol oxidase enzyme activity (50%), weight loss (2.8%) and pH (33%) increased. While the application of sodium alginate+ ascorbic acid preserved the lower levels of pH and the activity of polyphenol oxidize enzyme, it also controlled weight loss for 14 days.
