-
Observe
good picking procedures - i.e. pick grapes at lower temperatures.
Cease when temperatures rise.
Observe industry procedures with regards to packing grapes after rains - cease packing for 2 days.
-
Do
not allow picked grapes to remain in the heat.
Pack the grapes as soon as possible after picking.
The higher the ambient temperature the quicker the stems and fruit dry out.
-
The
packhouse temperature should ideally be below 20°C.
-
Use
a liner in the grape carton to minimize moisture loss.
-
Place
the Uvasys sheet on top of the grapes in the carton, shiny printed
side up, as per instructions on the sheet.
-
Use
the correct size sheet for the size of the carton and the weight
of grapes packed. If in doubt, contact us.
-
A
Uvasys Dual Release sheet is used if no pre-fumigation with
SO2
occurs.
-
If
the grapes are to be fumigated with SO2,
then use a Uvasys Slow Release sheet.
-
Uvasys
is designed to be placed directly onto the tables grapes. However,
if desired, a MAM (Moisture Absorbing Membrane) sheet or tissue
paper (with specification of <40gsm) may be placing between
the grapes and the Uvasys sheet.
Close the liner over the Uvasys sheet and seal the carton. This ensures that the Sulphur Dioxide remains in the carton.
-
Place
in pre cooler as soon as possibility to minimize decay and loss
of moisture.
-
Best
storage conditions are at -1°C and 95% Relative Humidity.
