The objective of this paper is the optimization of shrimp freezing process and evaluation of
the influence of phosphate addition on product yield and quality. A systematic experiment
was conducted to obtain data on yield and quality after the following process steps: immersion
in phosphate solutions, freezing, defrosting, and cooking. The best results were
obtained using phosphate and freezing the shrimps (Pleoticus muelleri) with liquid N2. The
use of phosphate was efficient in retaining water during thawing and after cooking. These
results were confirmed with the diminishing of drip loss during thawing and after cooking,
and with the increasing of moisture content after immersion.
