Document Summary
Some of the main types of modification in polysaccharides include the following; The two principle targets of the below polysaccharide are; Cross-linking in the polysaccharide is forming a tridimensional network where the chain of the polymer is linked by noncovalent or covalent bonds. A quantified amount of citric acid as a catalyst. Phosphate (sodium phosphate having 50% w/w on the weight of the citric acid employed) is employed with the catalyst ( acid). The solution of starch having the catalyst and cross-linking agents heated up to about 363 k, this temperature is maintained for about 2 minutes. After that, the mixture is cooled to 338k and then poured it to teflon coated a plate of. The cast films were then permitted to air dry and this cooling is conducted within 2 days (48 hours) after that it will be peeled off from the plates.
