Starchbased packaging coatingwith the addition of calamus root extract

Antimicrobial packaging coatings based on natural polymers are safer than traditional packaging for use in the food industry. The use of this type of packaging can not only affect the improvement of the environment by replacing synthetic polymer packages with a long decomposition period, but can also increase the shelf life of food products when antimicrobial additives are introduced into them. The article presents a study on the development of a starch-based packaging coating with the addition of calamus root extract, which has antimicrobial properties and is intended to prolong the shelf life of food. A study was conducted of compounds containing potato starch, glycerin, acetic acid, and calamus root extract in amounts of 0.5%, 1%, and 3% as an antimicrobial additive. The extract was isolated from calamus root powder in a Soxler laboratory apparatus. The samples were tested for antimicrobial activity against various microorganisms using the disco-diffuse method. Antimicrobial activity was assessed visually and the average value of the suppression zone was calculated depending on the degree of development of the test cultures relative to the surface of the control and modified material samples. As a result of the study, it was revealed that when the extract from the calamus root is introduced into the packaging material, microbial contamination is suppressed.
