Abstract:

A study in Côte d�??Ivoire entitled �??artisanal and industrial valorization of native cassava (Manihot esculenta Crantz) and yam (Dioscorea spp)�?� starches showed that the film produced with 4% starch cassava and 5% vegetable oil showed the most promising coatings capabilities. This film was designed without plasticizer and showed mechanical limits. So, the presence of plasticizer could overcome the fragility of the film, with a commonly used slurry of 15-40/g of glycerol in 100 g of starch. The properties of starch films can be further improved by producing composite films with incorporation of functional additives. Thus, in this present study, starchbased films have been strengthened with addition of a plasticizer (glycerol), an emulsifier (soy lecithin) and a preservative (potassium sorbate). These mixture led to produce biodegradable edible packaging based on native starches extracted from improved cassava varieties in Côte d�??Ivoire. This study is currently carried out at the University of Liege, Gembloux Agro-Bio Tech laboratory Quality and Product Safety Agro-Food. The optical, mechanical and water vapor barrier properties of the starch-based films containing 4% to 5% vegetable oil, glycerol (0, 15, and 25%), soybean lecithin (0 to 5%) and potassium sorbate (0 to 2 g) are investigated. The effectiveness of the optimal formulation for uses as coating of raw food crops (cassava roots, fruits and vegetables) and production of biodegradable packaging will be studied.
