Latest Patents

Kyoung-Sik Han holds two patents related to an encapsulation system designed for the protection of probiotics during processing. His latest patents disclose comestible products, such as beverage products, that contain encapsulated probiotic bacteria. These bacteria exhibit resistance to thermal and acidic conditions, ensuring their viability in challenging environments. The beverage products include at least one aqueous liquid and capsules made from a gelled mixture of alginate and denatured protein, with probiotic bacteria entrapped within the gel. The average particle size of these capsules is less than 1000 microns in diameter, with some being less than 500 microns. The methods for creating these encapsulated probiotics involve mixing sodium alginate, denatured protein, and active probiotic cells, followed by the addition of a divalent cation to initiate cold gelation. This process results in the formation of capsules that can be produced with a weight ratio of protein to alginate ranging from 1:1 to 9:1.
