Absorption studies suggested 1g. ascorbic acid per day as a prophylactic dose and 6g. ascorbic acid per day as a therapeu...

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 ...
