Technology for Reusable Edible Coatings

This patent discusses the technology of forming reusable coatings on the surfaces of containers and tableware using an edible gel composition that contains low-methoxy pectin, alginate, and metal salts. By adjusting the content of alginate and low-methoxy pectin, it is possible to change the gel strength and viscosity of the coatings. In particular, the content of low-methoxy pectin is shown to be crucial for the formation of coatings.

Traditional cleaning of tableware and containers requires a lot of effort and time. Additionally, the amount of detergent and water used is significant, placing a heavy burden on the environment. Further, the use of disposable plastic products is causing environmental issues. To address these problems, a reusable and environmentally friendly method is needed.

This patented technology forms reusable coatings on the surfaces of containers and tableware by using an edible gel composition containing low-methoxy pectin, alginate, and metal salts. This significantly reduces the labor of cleaning and decreases the burden on the environment. Moreover, by adjusting the content of alginate and low-methoxy pectin, it is possible to optimize the properties of the coatings.
