35. SUMMARY
Fruit pulping is modern way of storing the
perishable fruits. It helps in value addition, increase in
time of consumption and a way of providing raw
material for many other food products.
The pulping industries increases the national
income due to more requirements of pulp in international
markets. It also helps in employment generation and
empowerment of country.
