This is because the Philippines is still lagging at the rear of in article harvest technologies as as opposed to the developed nations.

Brings about of Write-up harvest losses

1)  Technological – Write-up harvest losses covers the pursuing causes…

  • Decay or rotting – Vegetable simply decay or rot when not adequately managed, in particular the leafy ones. Fruits previous a tiny for a longer period but they simply rot as nicely.
  • Yellowing – Yellowing generally takes place to leafy veggies. For fruits yellowing is a indicator of ripening and later on decay.

The more quickly it respires, the more quickly it rots. Higher stored food items delayed rotting.

Greens has 80 – 95 drinking water. This is misplaced to the ambiance via transpiration in particular throughout dry and very hot months.

two)  Differences in Morphology, Structure and Chemical Composition

The variations is dependent on what morphological parts the vegetable is…
