CARRIER MATERIALS FOR DRY PROBIOTICS (A REVIEW)

Aquaculture

To increase the yield of aquaculture commodities, many biological agents have been used, including the introduction of probiotic bacteria. Probiotics are living microorganisms that, when given to a host organism in sufficient quantities, will enhance its health. It is necessary for probiotic bacteria to meet a number of criteria in order to be used, including resistance to bile salts and low pH, ability to survive in the digestive system, production of antimicrobial compounds, ability to adhere to intestinal cells, mass production, ability to remain stable and viable in the environment for extended periods of time both in the laboratory and in the field, and a significant positive effect on the host. Among the difficulties faced by probiotic products in liquid preparations is the inadequacy of large-scale storage and delivery for liquid probiotics. This led to the development of new probiotic products in dry formulations (powder). The encapsulation method can be used to maintain and improve the qualities of probiotic bacteria. It is very significant to notice the role of the carrier material in the encapsulation process. Depending on the bacterial carrier emulator's physical and chemical characteristics, the drying environment, and the type of spray drying employed, the coating material will have an impact on the final output. Maltodextrin, talc, activated carbon, and rice flour are a few substances that can be utilized as coating materials in the production of dry probiotic products.
