Changes in Lipid Profiles of Dried Clams (<i>Mactra chinensis Philippi</i> and <i>Ruditapes philippinarum</i>) during Accelerated Storage and Prediction of Shelf Life
To predict the shelf life through
an Arrhenius model and evaluate
the changes in lipid profiles, two types of dried clams were stored
at 50 and 65 °C and collected periodically for analysis. The
predicted shelf life values of the two dried clam samples were 530
± 14 and 487 ± 24 h (24 °C), and the relative errors
between the actual and predicted values were 5.7 and 6.8%, respectively.
During accelerated storage, the peroxide value, <i>p</i>-anisidine value, thiobarbituric acid-reactive substances value,
total oxidation value, acid value, and free fatty acid content all
increased, while the levels of triacylglycerol, phosphatidylcholine,
phosphatidylethanolamine, major glycerophospholipid molecular
species, and polyunsaturated fatty acid (PUFA) decreased. Moreover,
content of phospholipid containing PUFA decreased significantly than
that of triacylglycerol containing PUFA. Results indicated that the
Arrhenius model was suitable for the shelf life prediction of dried
clams and accelerated storage caused loss in quality of dried clams
