description | The need of new food sources to satisfy human
requirements forces researchers to study any possible alternative
supplies. Therefore this study aimed to explore the
quality and digestibility evaluation of the protein fractions obtained
as a by-product of processing the shrimp exoskeleton
Litopenaeus vannamei. Shrimp exoskeletons were washed,
they were dried, mincedand they were brought under acid hydrolysis
and alkaline hydrolysis; released proteins were then
precipitated and characterized. 496 g of demineralized exoskeleton
were obtained from 1 kg of shrimp shell; out of these,
376 g corresponded to chitin and 120 g corresponded to
protein Total protein content was 33.80 ± 0.34 %. The digestible
protein fractions were 26.7 g and 92.1 g were insoluble
proteins. Of this latter fraction, the largest proportion belonged
to the scleroprotein type. The amino acid profile analysis
from the recovered proteins indicated that there were present
nine amino acids out of the ten essential ones, being leucine
the one with the highest proportion. In vitro digestibility was
shown to be up to an 83.7 %. Therefore, it was possible to
conclude that the recovery of digestibleproteins from shrimp
exoskeleton may be useful in diet formulation. |
