Influence du dextrane sur la filière sucrière au Cameroun

Résumé

Dextran is one of the various impurities causing losses in sugar processing, and develops rapidly on burned and stocked stalks. The main stage of dextran enrichment occurs during purification. The use of dextranase at pH 5 to 7, at temperature of 40 to 55 °C and reaction times of 20 mn on the crude juice allows the dextran to be eliminated. Industrial rules of hygiene and cleanliness preventing to avoid contamination during the process, together with reducing the time between fire cleaning, cutting of stalks and extraction of sugar, prevent the development of dextran.
