Keeping white fish spoilage to a minimum

By Fintan McConnell, Product Manager NCC Food Ingredients.

When it comes to fresh white fish, time is of the essence. From the moment the fish is caught and taken out of the water until it appears on the consumers plate, the clock is ticking. Naturally with fresh fish the need to ensure freshness is of paramount importance. However that is not to say that frozen fish does not also have its challenges. Regardless of it being fresh or frozen, as time passes white fish will discolour. Whilst this does not necessarily mean that the product has spoiled. Unfortunately most consumers will assume otherwise leading to a lower price or unsaleable product.

To counteract this loss in revenue and prolong the lifespan of (in particular) fresh or frozen white fish, it is recommended to use a fish whitening agent or a preservative. However not all whitening agents on the market are the same. Some simply whiten the product but don’t inhibit the oxidation process. Added to that, in my experience some varieties of white fish require an alternative approach.

Prolong the product lifespan, maximise revenue

Here at NCC Food Ingredients we work closely with UK and Irish seafood processers. In one such case the challenge was to prevent a loss of revenue as Monkfish fillets were suffering a reduction in quality due to delays in the processing chain. A range of traditional fish whitening products and stabilisers were trialled with little or no success. NCC Food Ingredients was approached to find a solution. Monkfish being a somewhat meatier fish than most white fish required a new innovative approach.

A custom solution was required

Working in conjunction with our partner Ph7 Food Technology we were able to provide a custom solution that addressed the challenges. Our solution recovered the appearance, moisture, texture and taste of the end product, as well as keeping it fresher for longer.

This was achieved by using 1% PEX R1 whitener combined with 0.5% T-40 whitener and then added to cold water that contained 2% salt. The fillets were then soaked in this solution for between 6 to 24 hours at a ratio of Monkfish to water solution 1:2. This resulted in a simple and economic solution to a potentially expensive problem.
