Abstract

Uroteuthis (Photololigo) chinensis L. is one of the most popular kind of seafood that accounts for about 20% of all cephalopod species caught in Vietnam. This study was aimed at developing a quality index method (QIM) scheme to assess the quality and freshness of Loliginid squids. The new method will be of benefit to consumers, fishers, seafood dealers, seafood industry businesses, and controlling entities. The QIM scheme for Loliginid squids was based on the changes registered for 10 sensory parameters, scoring from 0 to 28. The obtained equation for linear correlation with P-value < 0.05 during storage was Y = 1.083 X_tg + 2.866, with coefficient R² = 0.99. When preserved on ice, the Loliginid squids proved to have a shelf life of 10–12 days. The QIM program and the quality index equation provided a user-friendly, quick, and efficient scientific-based tool that can specify the storage time and estimate the remaining shelf life for Loliginid squids. The scheme can be combined with other chemical quality parameters of freshness to form a full quality assessment program for Loliginid squids.

FUNDING

The research received financial support from the Vietnamese Ministry of Agriculture and Rural Development (MARD), project “Research and evaluation of the post-harvest losses level on offshore fishing boats (falling nets, purse seiners, trawlers, pairtrawlers, handliners)” (20/HĐ-KHCN, 22.01.2018).
