PCT No. PCT/EP96/02217 Sec. 371 Date Feb. 23, 1998 Sec. 102(e) Date Feb. 23, 1998 PCT Filed May 23, 1996 PCT Pub. No. WO96/37112 PCT Pub. Date Nov. 28, 1996Method and apparatus for the continuous sterilization of a non-packaged biological liquid, particularly milk and its byproducts, containing bacterial and sporal loads, including the steps of a) gradually preheating the liquid to a preheating temperature proximate to a maximum temperature of the process; b) irradiating the liquid with an electromagnetic field with a frequency of less than 1 GHz so as to heat the product to the maximum temperature of the process; and c) rapidly cooling the liquid to a temperature of approximately 15 DEG before packaging. The preheating temperature attained during the preheating step a) is between 90 DEG C. and 140 DEG C. and the maximum temperature reached during the irradiation step b) is about 165 DEG C. with a thermal gradient between about 0.1 DEG C./s and 10 DEG C./s, so as to provide a high temperature heating of the liquid while preventing destruction or alteration of the active principles and organoleptic properties of the liquid. |
