Semi-preserved fish technology. Food additive (preservative) Varex-14

The range of semi-preserved salted fish products is extremely wide through the use of different fish species, kinds of cutting and a variety of pickles (oil, wine, mustard, and so on). Studies have shown that a food additive Varex-14 is universal: it is used in various technological schemes and contributes to maintaining the microbiological safety and nutritional value of semi-preserved fish throughout the extended shelf life at positive temperature.

As some gas-producing bacteria are insensitive to benzoate preservatives they cause bloat under favorable temperature conditions. Sometimes the bloat occurs extremely rapidly. Thus, the use of sodium benzoate is inefficient and unsafe in modern technology for semi-preserved fish.

The advantages of our technology

  • Positive storage temperature of semi-preserved fish products: 0° to +5°С.
  • Extended shelf life at 0°..+5°С:
    • for semi-preserved fish cut by pieces or carcass in various sauces and pickles – up to 30 days;
    • for semi-preserved fish cut by fillet-pieces, fillet-slices, fillet, roll or belly in oil or vinegar-oil pickles – up to 65 days;
    • for semi-preserved fish in other sauces and pickles – up to 100 days.
  • Extended shelf life at -5°..0°С: up to 120 days.
  • High sensory characteristics and natural flavour of matured fish including herring are preserved throughout the shelf life.
  • Safe food additive Varex-14 is used (does not contain hazardous ingredients: sodium benzoate (E211), parabens, antibiotics, etc.).
  • Varex-14 performs a complex effect: effectively slows down the processes of spoilage and the appearance of undesirable after-tastes (of oxidized fat, bitterness, etc.), contributes maturation, ensures the microbiological safety of finished product.
  • Easy-to-use.

For semi-preserved fishThe content of Varex-14 is regulated by sorbic acid. Residual content of sorbic acid in semi-preserved fish produced with our food additive is not more than 0.2%.

The ablility to store semi-preserved fish products at positive temperature plays an important role when retailers choose their suppliers, because not many refridge units are designed for a small negative temperature (0° to -6°C), and disturbance of temperature regime during storage and transportation significantly reduces the gustatory quality of semi-preserved fish. Varex-14 provides the "safety margin" at temperatures up to +5°C.

Since there are many different technological schemes of semi-preserved fish manufacturing (for whole fish and fillets), we are also able to advise your technologists on the application of Varex-14 with maintaining your well-proven technology.

With the ability to store product at positive temperature, extend its shelf life and maintain high quality, your semi-preserved fish becomes high-demanded by retailers and consumers and can be delivered to new markets abroad.

Using Varex-14, you ensure consistent quality of semi-preserved fish during shelf life, and also preserve the useful properties of product that customers appreciate.
