7 Refining (Juice, puree, paste) L
O
Survey of references:
L Use high refining pressures
O Reduce the holding time before the
evaporation (air presence in juice)
For Tamburini et al. (1999) lycopene concentration in puree obtained with a pulper
having 1.3 mm diameter holes was higher than in puree obtained with one having 0.8'mm
diameter holes; however, the difference, albeit statistically significant, was of negligible
practical interest (1%).
Shi and Le Maguer (2000) hypothesise a possible lycopene reduction related to
mechanical cell disruption.
Comments and topics-
In the field of refinement currently in use (0.6 - 2 mm), the operation would not appear to
be capable of causing lycopene reductions.
Is this step an RCPL ?
