the present study has shown that applying the UHPH condition of 300 MPa,80 c of inlet temperature and 144 c for 0.7 s at the homogenization valve was able to produce aseptically packaged soymilk microbiologically stable for 6 months of storage at room temperature, as commonly reached for conventional UHT treatments. Moreover, it showed higher colloidal stability with very low solid sedimentation during storage than UHT treatment.
