Development of Tuberous Crops
based food industry
- Dr. C.S. Weeraratna
Independent Consultant
In Sri Lanka a large number of food crops
remain neglected and under- utilized.
Tuberous food crops hitherto underutilized
have a considerable potential in many
areas
Importance of Tuberous crops
• Improves food security in the Country
• Increase employment opportunities
• Enhance export income
Overall Objective
The Overall Objective of the project is
development of tuberous crops to
strengthen the Government of Sri Lanka’s
initiatives to enhance the Food & Nutrition
Security
Tannias
• Allocasias and Colocasias (Yams) belong
to this group
Sweet Potato
Innala
Innala
• Called local potato and does not need
costly pesticides.
• • Grows well in wet zone.
• • High carbohydrate (20%) and protein
contents (1.5%)
• 2-3 t/ha can be obtained
Cassava
• Cassava is the third most important source
of calories in the tropics
• Tuberous crops are little affected by droughts or
floods
• When there is a disaster/destruction by
hurricanes or cyclones tuberous crops are least
affected and remain in the ground for
smallholders to consume;
• They are nearest to their homes.
• These crops are free of pests and
diseases
• less costly to cultivate.
• Yields are relatively high
• • High yields (3-5 t/ha) are obtained
• • Can be grown in the wet zone and dry
zone
• These have high carbohydrate (25%) and
protein (2.0%) contents.
• Can be cultivated as an inter crop in
coconut lands
Development Strategies
• Identify the tuberous crops grown in the
country
• Their agronomic characters
• Promote their cultivation
• Develop value added products based on
these crops

Post-Harvest Technology and Packaging for Tuberous
crops
1 Post Harvest & Packaging Technology Development
In view of potential post-harvest losses, development and
application of post-harvest technology is a strategic issue for
the development of Tuberous crops based food industries. The
following four projects will be developed to address this
strategic issue:-
• Study and development of keeping qualities through
preliminary packaging or suitable treatment
• Adaptation of Solar Powered Cold Rooms
• Adaptation of Solar and wind Powered Driers
• Development of Tuberous crops Dehydration Technology

Packaging Packaging is a means of providing the correct environmental conditions for food during
the length of time it is stored and distributed to the consumer.
Developing packaging technology for both raw tuberous crops and the value added
products for the following reasons:-
• Adequate package aids distribution
• Rapid and reliable distribution helps reduce malnutrition, improves local food supply
and allows consumer more choice in food available
• Packaging and distribution reduce post-harvest losses
• Larger market created by appropriate packaging allows producers to increase their
demand
A project will be developed to introduce appropriate packaging technology for tuberous
crops based food industry with following functions:-
• Keep the product clean and provide a barrier against dirt and contaminants
• Prevent losses
• Provide protection to the food against physical and chemical damage and insects
and rodents
• Provide identification and instructions so that food is used correctly and have sales
appeal

Value addition for Tuberous crops
1.1 Value addition
There is hardly any value addition to tuberous crops in Sri Lanka.
They are mostly consumed as a traditional item of food either after
boiling or after cooking into curry. The following seven projects will
be developed for value addition and publicity:-
• Cassava flour – from industrial processing using wet milling.
• Cassava value added – chips etc
• Potato chips
• Sweet potato for noodles
• Food for the table – soup, porridge, from sweet potato and raja
ala
• Utilization of leaf, stem etc for human food
• Publicity for popularization of food for the table
