THE IMPORTANCE OF PROTEIN HYDROLYSIS to obtain amino acids and polyamines naturally, without the addition of any chemical product, while guaranteeing the complete absence of: antibiotics, weed seeds, pathogenic germs.
The Grena production process (THP®), wet thermal hydrolysis, is based on European directives transposed into Italian law by Regulation 1069/2009.
Thermal treatment of the animal organic matter is carried out in cooking autoclaves that use indirect jacketed steam as the thermal medium produced by the boiler.
It is precisely during the cooking phases that hydrolysis takes place, releasing the amino acids contained in the proteins; the subsequent aggregation of certain amino acids produces the peptides and carboxyl groups later present in Grena products.
During the thermal process, the moisture in the cooking liquid evaporates (ETHP®).
The autoclaves are kept under slight negative pressure by extracting the steam, which is then condensed (cooling and/or pyrolysis), yielding the finished liquid product: liquid polyamine extract.
Product quality checks: Grena carries out constant checks on incoming raw materials as well as finished products, through weekly analyses performed by certified external laboratories (accredia).
