AGRE-0029 Improvement of Sunflower Dehulling Capacity 1 April 1991 - 30 April 1992

For many oil crops, the fibrous by-products left after oil extraction are marketed as animal feed. For several crops, the feed value for fowl and monogastrics is enhanced by the protein content of the residues. However, in the case of sunflower the use of the meal in animal feeding has been limited due to the high fibre content caused by residual seed hulls. Industrial dehulling is already performed in some countries (Argentina, France, Spain, USA), but the meal quality in terms of digestibility for poultry and monogastrics such as pigs, as well as protein content, is very variable. This reflects a large variations in the extent of dehulling. Experiments on technology for dehulling sunflowers carried out in France indicated that one of the most important factors affecting this is the properties of the seeds themselves. This ECLAIR project approached the problem over a broad front, aiming to obtain a better knowledge of the many different scientific, technical and economic areas (including plant physiology, agronomy, breeding and technology) for improving sunflower dehulling ability. A dehulling-sorting system has been established, as have factors (environmental, genetic and process related) which affect dehulling. As a result of this work a new process flowsheet has been designed.
