Titre espagnol : Efecto del tostasto sobre los tocoferoles de semillas de calabaza (Cucurbita pepo)

Abstract : The effect of roasting at high temperatures on the Vitamin E in hulled gourd seeds of Cucurbita pepo was studied. Roasting at 140°C for 5 min induced a swelling of the seed with an increase in volume of 43%, and a weight loss of 6.5%. The seed acquired the desired puffed-up appearance. The water activity of raw seeds was 0.544 and decreased during roasting to 0.105. Cucurbita pepo seeds contained 51.0% fat. Tocopherol content of roasted seeds was 68mg/100g oil and of non roasted seeds was 107mg/100g oil. ã-tocopherol represented 96% of the total tocopherols. Total tocopherol loss during roasting was 36%. â-tocopherol loss was the highest at 50%; for á-tocopherol it was 41% and for ã-tocopherol it was 36% (Résumé d'auteur)
