Frozen Fish & Frozen Seafood Displays in Grocery Store & Fish Market Cabinets

Even frozen packages of fish and assorted seafood should look and smell fresh. Frozen fish fillets or steaks should be white or pink depending upon the species, while whole fish should have brightly colored or metallic scales and red or pink gills.

Yellow and green wavelengths are the most damaging wavelengths in the visible spectrum, and their predominance in regular fluorescent lighting can distort the natural colors of finfish and seafood and make ice beds look green or yellow. PROMOLUX fluorescent lamps and LEDs emit a more balanced range of wavelengths, which results in true color displays.

Decomposition of Frozen Retail Fish and Seafood Displays

Frozen fish is often packaged in a folded sleeve of plastic that is sealed shut with an ice glaze. In a damaged or loosefitting package that allows air in, display case lighting can trigger lipid oxidation of fish fats and lead to rancidity, which occurs even in sub-freezing temperatures and is notable as a brown or yellow discoloration and a strong fishy odor.

Radiation from display case lighting can accelerate the dehydration of fish, which may be seen as frost from drip as the cells lose the ability to retain water, or in extreme cases, freezerburn, which gives unpleasant flavors and white or yellow patches.

Frozen seafood should be stored at 0°F to -10°F (-17°C to -23°C); at these temperatures it will maintain its quality twice as long as at 10°F to 15°F (-12°C to -9°C). Fish kept frozen at -22°F can last from 9 months to 2 years.

Frozen puddles and runny color on the skin indicate that the fish has thawed and was refrozen. Seafood that was frozen slowly or stored at warm or fluctuating temperatures will be tough with excessive drip and a soggy, chewy, bland flavor, or may have a soft texture from structural damage caused by large ice crystals.

PROMOLUX Lights Are Unique To Fresh Food Displays

Seafood Case LightingCompared to other fluorescent lighting, PROMOLUX lights were developed especially for fresh food and perishable food displays including seafood counters.

PROMOLUX fluorescent and LED lights work to successfully filter over 86% of the UV B radiation and 52% of UV A radiation which compromises a foods chemical makeup and nutritional integrity.

Simply switching to PROMOLUX lamps and LEDs helps fish mongers and seafood markets save thousands of dollars every year in what would have been otherwise spoiled and discarded product.

Seafood departments experience the greatest shrinkage of all supermarket departments. Dehydration, drip loss, and bacterial growth are all accelerated by slight temperature increases. Rancidity is triggered by oxygen and light. <more...>

Seafood display lighting can raise the surface temperature of fish and seafood. In unrefrigerated display cases filled with ice, the temperature two inches above the ice has been measured at room temperature. <more...>

Temperature control of smoked fish is essential to prolong shelf life and avoid botulism poisoning. <more...>
