| Abstract | ||
| This study have been conducted in the experimental farm of the department of plant production, faculty of environmental agriculture science, Arish university, during February – May 2022, to evaluate three major methods of sage drying under North Sinai conditions, eg: traditional methods of direct sunlight drying, and shade drying , third method used electric oven-drying at two different temperatures 45c°and 60c°.Postharvest treatments have been achieved using the first cut of sage (Salvia officinalis L.) by in order to select a more suitable drying method of preservation. Some chemical, physical, and biological analyses have been using explants and the extracted sage essential oil. Results indicated significant differences among drying methods, and reported that selection of a drying method is depending on the aim of drying, since, shading recorded highest value of moisture, ash and oil content, while oven-drying improved antioxidant activity and inhibited microbial activity, as well as enriched both of fat, carbohydrates and plant pigment contents. Ranges of (7.89 – 9.00), (8.56 – 9.93), (32.21 – 33.50), (8.09 – 8.79), (4.01 – 4.76), (56.22 – 62.11), and (2.57 – 3.60)%, have been recorded concerning moisture, ash, fiber, fat, protein, carbohydrates and essential oil contents. Highest contents of both of 1.8-cineole (46.25) have been obtained by sun drying, and camphore (19.50) using shading, β-pinene (7.12) at 45c°of oven-drying, and (-)- bronyl acetate (2.79) due to 60c°. | ||
