Abstract
Cellulose is the most abundant biopolymer in the world and one of the most important known. The use of cellulosic structures at the nanoscale has been investigated because of its advantages over larger counterparts such as larger surface areas, thus contributing to more promising applications in rheology control in colloidal systems. The main routes of obtaining nanocellulose involve the exploitation of plant resources, however, some bacteria are capable of producing bacterial cellulose, which, like those of vegetal origin, serve as a source for obtaining nanofibers and nanocrystals. Thus, the objective of this project is to study the modification of the rheological behavior of colloidal systems containing water and water-soluble polymers (alginate, gelatin, hydroxypropylmethylcellulose and pectin). The study will make it possible to obtain a better polymer matrix composition to be applied as a potential substitute for non-biodegradable packaging materials. In addition, because it is edible the material will be applied in the food area in the wraps making instead of the fresh cabbage used in Arab food. At certain times of the year, the production of this food in some countries is hampered, due to the weather and other inclement weather. This project is expected to promote advances in solution characterization and interactional knowledge in colloidal systems composed of nanocellulose and biopolymers so that the study enables new applications of the obtained materials.
