Effect of HHP on molds and yeasts
The number of surviving cells in gooseberry pulp after HHP
treatment was determined by monitoring M&Y. The initial count of
M&Y in untreated pulp was 3.1230.063 log CFU/g. M&Y in the
pulp was not detected after HHP treatment (Day 0). After 60 days of
storage, the inactivation achieved with the different treatments
depends on the pressure intensity. It was observed that the highest
the pressure and time exposure, the highest the inactivation
(Huang et al., 2013). In particular for treatments above 400 MPa/
3 min, M&Y were not detected. This study focused on the changes
of the quality aspects of the gooseberry pulp after HHP treatments,
and the analyses concerning the changes were presented as
