Definitions

  • the present invention relates to a process for treatment of fresh food, such as fish, shellfish and meat.
  • a drawback when using preservation agents in the form of bactericidal agents and such is, however, that it is difficult to avoid that the quality of the raw material decreases, for example smell and taste changes. Moreover, the added agent must of course be harmless to humans. Furthermore, the added agents must not be too expensive, which would make the process uneconomical. As regards deep freezing, it is often difficult to keep the raw material at the low temperature from the time the fish has been captured until it is delivered to the consumer. If the temperature increases the preservation effect decreases, after which the process of decomposition starts. Even if it is possible to keep the low temperature during freezing, the raw material is impaired by the freezing and thawing process, respectively, which sometimes gives impaired characteristics regarding consistency.
  • a cooling liquid for fresh fish comprises the following components: water; one or more inorganic salts, preferably NaCl; one or more polyols, preferably glycerol; and ascorbic acid.
  • this cooling liquid By using this cooling liquid the fish can be cooled to - 1°C to -2°C without freezing of the fishmeat. The purpose with this cooling liquid is thus to lower the freezing point so that the fish does not become frozen at the storage temperature used.
  • antioxidants such as ascorbic acid, increase the storage stability of food. However, the increase in storage stability is very short and not an alternative to deep-freezing.
  • the present invention provides a method of treating fresh food, such as fish, shellfish and meat, to improve its storage stability so that the smell, consistency and taste of the food is preserved during a longer period of time.
  • the process is characterized in that the fresh food is treated with a solution comprising at least two antioxidants having different antioxidative characteristics, i.e. different oxidation rates. By using these different antioxidants a prolonged antioxidative effect is provided.
  • the anitoxidants are chosen from antioxidants having rapid, intermediate, and slow oxidation rates, respectively.
  • the antioxidants according to the invention are selected from the following: ascorbic acid, astaxanthin, sodium ascorbate, calcium ascorbate, ascorbylic palmitate, ascorbylic stearate, tocopherol-rich extracts, ⁇ -tocopherol, ⁇ - tocopherol, ⁇ -tocopherol, propyl gallate, octyl gallate, dodecyl gallate, isoascorbic acid, sodium isoascorbate, butyl hydroxy anisol (BHA), butyl hy- droxy toluene (BHT), lecithin, sodium lactate, potassium lactate, calcium lactate, citric acid, sodium citrates, potassium citrates, calcium citrates, L- tartaric acid, sodium tartrates, potassium tartrates, sodium potassium tar- trates, phosphoric acid, sodium phosphates, potassium phosphates, calcium phosphates, sodium malate, sodium hydrogen malate, potassium mal
  • a presently preferred antioxidant is green tea which in itself shows a spectrum of antioxaditive characteristics.
  • the solution used in the process according to the invention may be a water solution, wherein water soluble antioxidantes are used, or an oil solution, wherein fat soluble antioxidantes are used.
  • the oil solution may comprise any edible oil, for example rape-oil.
  • the solution is added to the food by dipping, painting or spraying, wherein the latter has given especially good results for water solutions.
  • the solution also comprises antioxidative mineral agent(s), such as zinc and selenium, which has the additional function of stabilizing the solution, i. e. gives longer storage stability of the food.
  • antioxidative mineral agent(s) such as zinc and selenium
  • the preferred food for treatment according to the invention is all kinds of fish.
  • antioxidant solutions were used containing representative examples from rapid, intermediate and slow acting antioxidants.
  • a member from each of these groups is present. It is realised that the choice is dependant on the raw material, i. e. the food to be treated. For ex- ample, the size of the antioxidant will influence its penetration depth into the selected raw material.
  • the treated food was filleted fresh whitefish having a weight of 300-400 g.
  • Water-soluble antioxidant solution was added on both sides of the fish, after which it was kept, together with an untreated control, in a refrigerator at +7°C to +8°C.
  • the storage stability was judged after the levels of smell and consistency.
  • Untreated fish (control) consistency impairment after 5 days, smell impairment after 6 days.
  • Treated fish consistency impairment after 8 days, smell impairment after 9 days.
  • the results from example 1 show that the fish treated according to the invention exhibited about 50% better storage stability.
  • the treated food was filleted fresh whitefish having a weight of 700-800 g.
  • Water-soluble and oil-soluble antioxidant solution, respectively, were added on both sides of the fish, after which it was kept, together with an untreated control, in a cold-storage room at +2°C to +4°C.
  • the storage stability was judged after the levels of smell.
  • Treated fish (water-solution) smell impairment after 1 1 days.
  • Treated fish (oil-solution) smell impairment after 10 days.
  • the treated food was about 48 hours old (since the capture) filleted Baltic herring having a weight of about 100 g per fish.
  • Water-soluble and oil- soluble antioxidant solution, respectively, were added to both sides of the fish, after which it was kept, together with an untreated control, in a refrigerator at about +6°C.
  • the storage stability was judged after the levels of consistency and smell.
  • Untreated fish (control) consistency impairment after 5 days, smell impairment after 5-6 days.
  • Treated fish water- solution: consistency impairment after 7 days, smell impairment after 8 days.
  • Treated fish consistency impairment after 6 days, smell impairment after 7 days.
  • the results show a clear improvement for the treated fish, wherein better results were obtained for the water- solution than for the oil-solution.
  • the treated food was frozen and thawn shrimps. Antioxidant solution was sprayed on the shrimps. Controls were sprayed with the same amount of water. The specimens were kept in a cold storage room at +2°C to +4°C.
  • Untreated shrimps control: smell impairment after 3 days.
  • Treated shrimps (tea-solution): smell impairment after 8 days.

Abstract

L'invention concerne un procédé de traitement des denrées alimentaires fraîches, notamment du poisson, destiné à améliorer la stabilité au stockage. Les denrées alimentaires fraîches sont traitées avec une solution contenant au moins deux anti-oxydants ayant des caractéristiques d'antioxydation différentes, c'est-à-dire des taux d'oxydation différents. Ce procédé constitue une véritable amélioration dans la stabilité au stockage des denrées alimentaires.
