Shrimp's waste (dried head or shell) was found of high protein content and
high level of minerals especially Ca, P, Na and Zn. The amino acids profile
of the dried shrimp's shell proved to be of higher values than the shrimp'
s head. Glutamic acid was the abundant amino acid in both dried samples. Th
e saturated: unsaturated fatty acids ratio was 1:1.63 for the dried shrimp'
s head and 1:1.51 for the dried shrimp's shell. The dried shrimp's shell an
d head appeared to be free From aflatoxines (B-1, B-2, G(1) & G(2)) concent
rations. Also the two dried samples proved their safety from the bacteriolo
gical point of view.
Two suggested potato croquettes recipes containing either 5% dried shrimps
head or 5% shrimp's shell, preferred by the panalysts, were found to contai
n high values of macro elements and rare values of micro elements. The EAA
: TAA ratio of these two suggested recipes were 1:1.95 and 1:2.29 for the r
ecipes containing dried shrimp's head and shell, respectively. Their in vit
ro protein digestibility (IVPD) ranged from 60.44 to 67.68%. Toe total satu
rated fatty acids were found Lower than the total unsaturated fatty acids i
n the two suggested recipes. Potato croquettes recipes containing either 5%
dried shrimp's shell or head were found of acceptable overall quality (aro
ma, taste, appearance, texture and color) to the panalists.
