Vitramines and Preservatives

  • Vitamins are substances without energy value but nevertheless essential for the body. Two main types of vitamins:
    • fat-soluble vitamins (i.e. which can dissolve in fat): A, D, E, K;
    • The water-soluble vitamins (i.e. which can dissolve in water) of group B (B1, B2, B3 or PP, B5, B6, B8, B9 and B12) and C.
  • Chemical preservatives are authorized additives that manufacturers use to extend the shelf life of food. They slow down the growth of microorganisms present in food and protect it from the effects of oxygen.
