Bacterial Nano Cellulose (BC) is a biopolymer produced by bacteria of the genus Komagataeibacter, which has gained attention in the food and packaging industry due to its unique properties.
Although its production is costly, advances in cultivation and processing methods could make it more affordable.
In this article, we will explore the applications and benefits of Bacterial Nano Cellulose in the food and packaging industry.
Optimization of Variables in the Production of Bacterial Nano Cellulose
Controlling process variables such as pH, aeration, and temperature is crucial to improve the production of Bacterial Nano Cellulose. The ideal pH for the production of Bacterial Nano Cellulose is usually between 4.0 and 7.0, and must be monitored to avoid the accumulation of metabolites that affect performance.
CULTIVATION MODE
Static and agitated cultivation are common methods for producing Bacterial Nano Cellulose. Agitated cultivation optimizes the production of Bacterial Nano Cellulose by mixing oxygen, but can cause mutations in cells.
Processing of Bacterial Nano Cellulose
The post-processing of Bacterial Nano Cellulose includes two steps: separation and purification. Bacterial Nano Cellulose is extracted from the culture by filtration, centrifugation, or direct collection, depending on the cultivation method.
Forms of Bacterial Nano Cellulose
Bacterial Nano Cellulose can present in various forms, such as intact membranes, disassembled, or nanocrystals (BCNC). Each form has specific applications in the food and packaging industry.
Main Applications of Bacterial Nano Cellulose in Food
Bacterial Nano Cellulose is a dietary fiber approved by the FDA as safe for food. Its main advantages include indigestibility, mouthfeel, and ability to improve food texture.
