Food is one of the most important needs of
the human being. As world's population is increasing day by day and production
of food products is decreasing in comparison with same. Hence there is need of
.food processing in this era. After harvesting food products losses are higher
due to some major physical, chemical and environmental factors. To reduce these
post-harvest losses there is need of food processing. As per different studies
and statistical analysis post-harvest losses in the world are about 65 million
tonnes. This overall huge amount is worth $12500 million per year. This is one
of the major challenges in the world. Hence to minimize these losses is
important task to complete requirement of world’s population.
Firstly in order to minimize these losses
several operations such as drying, sterilization and high pressure processing
etc. should be designed in proper way and this is duty of food process
engineer. Second important work of food engineer is to develop a plant design
for different raw products to convert it into consumable.
Therefore overall purpose of food process
engineer is to design operation process for reduction in post-harvest losses
and also to develop operation process for conversion of raw food material into
a edible food product as per need. This can be done by using different
techniques which may be thermal or non- thermal.
