Production Of Mosquitoe Repellants Insecticides (Mosquito Coil) Using Orange Peels (Cestrum)

1.0 Introduction

Starch can be obtained from cassava, sorghum, maize, sago and potatoes. But this project focused on the production of starch from cassava. Starch can be cross-linked a product that will be suitable for noodle, salad cream custard making. Normally it is easier to make this product from corn and potatoe starch, but cassava which is readily available and cheap can be employed to meet the demand of the people.

Other synthetic starch produced from cassava includes; carboxymethyl starch (which is produced when one of the hydrogen atom of the starch is replaced by carboxymethyl groups, starch acetate, starch xanthate and hydroxyl alkyl starch. These are used as thickening agents, sterbilizer and emulsifier in products. Cassava starch when treated with phosphate are used in frozen products when they are defrosted to prevent them from dripping. This study investigated the production of starch from cassava and preparation of cross-link derivatives.
