could reduce the freezing loss, vice versa, increase the thawing yield and
cooking yield of the frozen shrimp comparable to the use of the
commercial phosphate compound. Even though lysine and arginine
treated uncooked sample indicated a reddish color, there was no
significant difference in the color preference of any cooked products.
Sensory evaluation showed that panelists liked the arginine
treated sample more than the STTP treated sample. Adjusting pH of
lysine and arginine (1.0 g/100 ml) to 8.0e8.7 resulted in shrimps
with comparatively same WHC during freezing and cooking with
similar color change compared to treatment with STPP. The results
indicated high potential of using the amino acids, lysine and arginine,
as phosphate alternatives to improve the quality of white
shrimp product in the frozen shrimp industry.
