This study has demonstrated the effectiveness of the glazing process as a protecting agent for frozen shrimp. Glazing made with time of immersion of 15 and 20 s showed best protection when compared to 5 and 10 s, i.e., stable pH and lower N-TVB values.
No significantly difference was observed between 15 and 20 s. For future studies or industry application, 15 s of immersion, resulting 15%, 18% and 19% of glazing (product −18 °C, −25 °C and −30 °C, respectively) could be applied to frozen shrimp to protect against dehydration and chemical changes (during 180 days of storage).
Then, a reasonable range of water uptake could be between 15% and 20% to guarantee the final quality. Nevertheless, abuse has been reported with coatings as thick as 25–45% (or up), but the most appropriate way to attain quality assurance must be to introduce the standard procedures for ice-glazing, and complying to a regulated glazing content are important to the producers and consumers.
