The trimming wastes of some vegetables such as external leaves of lettuce, alcapucci, cabbage, cauliflower (stem
& leaves) and artichoke (leaves and outside bracts) were utilized to prepare vegetable - waste powder (VWP). Gross
chemical composition, dietary fiber, mineral content, bioactive components, antioxidant activity and antimicrobial
activity were studied. Also the utilization of this powder in preparing some Egyptian common foods, such as Falafel,
Jew᾽s mallow stew (Mulukhiya), lentil soup and Bessara as well as some bakery products such as cake and biscuits
(Menain) was studied and evaluated from the organoleptic point of view.
The results showed that the VWP contained higher amount of protein, dietary fiber, carotenoids, ascorbic acid
and flavonoids. The methanolic extract of powder had antioxidant and antimicrobial activities. The results also showed
that all the prepared products containing the different percentages of VWP were well accepted by the panelists.
