min, 10C);
3. UV radiation at a dose of 1 kJ/m2;
4. Heat shock by immersion in hot water at 95C for 30 seconds.
Results showed that UV radiation treatment and heat shock were effective in reducing the initial microbial population by about 1 log unit, and in maintaining the microbial load below the recommended limits (6-7 log CFU/G total aerobic mesophiles) during 10-day storage. On the contrary, treatments with chlorine and ozone were not significantly effective in reducing the microbial load.
