Resistance of vegetative cells and ascospores of heat resistant mold Talaromyces avellaneus to high pressure treament in apple juice
Original language description
Thermoresistant mould including Talaromyces avellaenus are frequent microbial contamination of fruit juices and purees, which are supposed to be one of the food product suitable for pressure pasteurisation. The effect of high pressure and thermal treatment on survival of vegetative cells and ascospores of T. avellaneus was studied. The vegetative cells T. avellaneus were very sensitivee to high pressure, the sufficient pressure treatment for the reduction by 6 orders was 200 MPa at 17 °C for 60 min or 300 MPa at 17°C for 5 min. The ascospores T. avelaneus in apple juice (rf 10.9 °Brix) were relatively resistant to the high pressure treatment, the application of 700 MPa at 17 °C or 25 °C for 60 min reduced the concentration by 3 or 2.5 orders respectively. Sufficient inactivation rate was obtained when the combination of pressurisation and gentle heating was used, the total reduction (by 6 oders) was reached at 700 MPa at 60 °C for 60 min. In the case of traditional thermoinactivation,
