The European Union Easy2Cool “Project CRAFT 1999-71845” performed some tests, where different parts of cow and chicken were stored into a conventional cold store and PRS Reefer Equipment.
Macroscopic aspects (color, scent, and consistency), as well as analytic aspects (weight and microbial load) were analyzed with the following conclusion: “The Passive Refrigeration Systems are the ideal solution for the preservation of meat, poultry and dairy products”.
The bacteria growth of cow meat in a conventional reefer cold store increased from 1.000 UFC*cm² at the beginning of the test up to 4.350 UFC*cm² and, in PRS Thermobox, increased to 1.750 UFC*cm² in the same period.
Different parts of a chicken were stored into conventional and PRS Reefer Equipment.
The most common microbial contaminants responsible for food poisoning have been taken into consideration:
After 3 weeks, the coliform charge of poultry stored in conventional cold store amounted to 93.333 UFC*cm2, about 5 times more than the coliform charge on poultry stored in PRS Thermobox.
