Résumé

Results were compared with those obtained for milk stored under the same conditions, but heated previously with a conventional system. Heat treatment of milk at 80 °C for 15 s and 90 °C for 18 s did not produce losses of vitamin B1. On the contrary, after 2-3 days of storage at 4.5 plus or minus 0.5 °C, vitamin B1 content of microwave- and conventionally-treated milk decreased by about 4%, resulting in 16-18% loss after 15-16 days. There were no differences between losses observed in milk heated with the microwave unit or with the tubular heat exchanger.
