Temperature fluctuations found to harm fish quality in cold chain logistics, according to Chinese researchers

A recent study has revealed how temperature fluctuations during cold chain logistics can significantly impact the quality of seafood, particularly large yellow croaker (Pseudosciaena crocea), a valuable and highly nutritious fish. Conducted by researchers from Zhejiang Gongshang University, the study shows that inconsistent temperatures lead to the breakdown of fish quality, posing challenges for both producers and consumers. The research, published in Food Science of Animal Products, explored the effects of varying temperatures on large yellow croaker, a species widely farmed in mariculture. Despite its high nutritional value, yellow croaker is highly perishable, making its storage and transport particularly difficult. Temperature control during transport is crucial to maintain its freshness, yet this research shows how even minor fluctuations can trigger spoilage. Through a carefully designed cold chain simulation model, the research team tested temperature variations from 4°C ...
