Abstract
The whole oyster and its three independent parts (adductor muscle, visceral mass and mantle) were processed into ready-to-eat (RTE) samples and stored at 40 °C for 8 weeks. During storage, the whole oyster samples showed liquid exudation and progressive darkening. In contrast, the color of the visceral mass sample, mantle sample and whole oyster sample deteriorated more obviously than that of the adductor muscle sample. This may be due to the higher contents of transition metal ions, lipids and reducing sugars in the formers, which promote lipid oxidation, Maillard/Maillard-like reaction, and phenolic oxidation - the main cause of color deterioration. The exuding liquid, containing browning reaction substrates such as lipids, sugars and polyphenols as well as browning reaction products, directly stains the adductor muscle while also indirectly accelerating its browning reaction, ultimately leading to uniform discoloration throughout the whole oyster sample.
期刊介绍:
LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
