:: Washing Of Subtropical Fruit
We have done some work in the post harvest aspects of washing various sub-tropical fruit.
We will outline in brief our results for each of the fruit types.
LITCHI - at 1 litre Harvest Wash WT per 1000 litres of water we maintain the distinctive
red colouration of the skin. This treatment will also assist in reducing the microbiological
growth of fungi and bacteria in the wash water.
BANANA - at 1 litre Harvest Wash WT per 1000 litres of water we were equivalent to the
prochloraz fungicide used to protect the banana against stem end rot and anthracnose.
Work was undertaken by the institute of Sub Tropical Crops in Nelspruit by Dr Frans Kruger
and his department.
We have done hardly any evaluation of our technology on : guava, papay, mango or
pineapples.
For mangoes, we understand that most, if not all, post harvest problems which do manifest
during the treatment in the packhouse OR distribution chain actually have commenced at
pre-harvest.
Harvest Wash WT at 1 to 2 litres per 1000 litres of water can be used to minimise the
food safety concerns related to washing of mangoes.
Owing to the fact that one can measure Harvest Wash WT simply and accurately in the
packhouse makes it one of the few chemicals which will readily meet the HACCP requirements
of a food safety programme.
