There are a wide variety of food processing operations are be divided into four broad categories. Ambient temperature processes. These include
cleaning and sorting; peeling, chopping and shredding and milling; - filtration, centrifuging, expression, extraction and membrane processes; mixing, blending and forming.
Thermal processes. These are processes involving heating and include pasteurization and sterilization; evaporation; and various cooking processes. Low temperature processes; chilling and freezing.
Fermentation processes Post processing operations; packaging and storage

The term Water-Energy nexus refers to the fact that water and energy are inseparable/connected. This is because:
Water is required to produce energy.
Energy is required to make use of water.

Renewable energy resources such as solar, wind and tidal are readily available and do not require fuel processing and associated water inputs
The agri-food supply chain accounts for 30% of the world’s energy consumption and is the largest consumer of water resources, accounting for approximately 70% of all freshwater use.
