2. Africa Rice’s Perspectives on
Processing and Value Addition
• Post harvest and value addition issues have been
made a priority in the National Rice Development
Strategies of many African countries.
• Training programmes lined up for national
scientists, extension workers, farmers, millers,
parboilers and marketers.
4. Grain quality evaluation
• Basic support in grain quality evaluation to
agronomy and breeding projects
• Physico-chemical analysis carried out on 470 O.
glaberrima varieties.
• Another batch of 500 O. glaberrima samples
have been prepared for analysis.
• Starch structures and pasting properties as well
as the glycemic indices will be determined for this
batch.
6. • Gelatinisation temperature - Alkali Spreading Value
• Cooking properties
• Pasting Characteristics - Rapid Visco Analyser
• Textural properties - TA-XT Texture Analyser
• Gel consistency
• Amylose content - Amylose Auto Analyser
7. Mechanization
- The following equipment for mechanization are
being evaluated :
- Planters
- Row weeders
- 4 different models of mini-combine harvesters.
