Proximate composition of products and raw materials was determined using AOAC (1998) methods:
Moisture (964.22), samples were drained in a conventional oven at 105 C to constant weight; Proteins (984.13), by Kjedahl method using 6.25 as the nitrogen-to-protein conversion factor; Ash
(923.03), samples were burned in a muffle furnace at 550 C to obtain white ash; Lipids (920.39), by Soxhlet technique. Total carbohydrates were calculated as difference
