Pearl-like capsule and method of manufacturing the same

Abstract

The invention aims to provide a pearl-like capsule that can encapsulate a large amount of fatty substances and a method of manufacturing the same, wherein the pearl-like capsule is less deformable and/or less shrinkable even under freeze-thaw and thus is convenient for transportation and preservation. The pearl-like capsule includes a droplet having an outer surface and a 0.5 millimeter to 15 millimeter diameter, and a water-soluble macromolecule, fatty substances, a water-soluble multivalent metallic salt, sake lees, and starch. The pearl-like capsule also includes a water-insoluble coating of alginate on the outer surface of the droplet, and a glycerine coating on the water-insoluble coating of alginate, wherein the sake lees include amino acid and are 1% to 10% by weight of the droplet, and the starch is 10% to 20% by weight of the droplet.

What is claimed is: 
     
         1 . A pearl-like capsule comprising:
 a droplet having an outer surface, a 0.5 millimeter to 15 millimeter diameter, and including a water-soluble macromolecule, fatty substances, a water-soluble multivalent metallic salt, sake lees, and starch;   a water-insoluble coating of alginate on the outer surface of the droplet; and   a glycerine coating on the water-insoluble coating of alginate,   wherein the sake lees derive from any sake selected from a group consisting of Junmai Daiginjo-shu, Daiginjo-shu, Junmai Ginjo-shu, Ginjo-shu, Special Junmai-shu, Junmai-shu, Tokubetsu Honjozo-shu, Honjozo-shu, and Futsu-shu,   wherein the sake lees include amino acid,   wherein the sake lees are 1% to 10% by weight of the droplet and the starch is 10% to 20% by weight of the droplet.   
     
     
         2 . The pearl-like capsule according to  claim 1 , wherein said water-soluble macromolecule is a quince seed mucilage. 
     
     
         3 . The pearl-like capsule according to  claim 1 , wherein said water-soluble multivalent metallic salt is water-soluble calcium salt. 
     
     
         4 . A method of manufacturing a pearl-like capsule 0.5 millimeters to 15 millimeters in diameter, the method comprising:
 removing hulls of rice to obtain rice kernels;   performing alcohol fermentation of the rice kernels to obtain sake and sake lees;   separating the sake and the sake lees;   contacting a droplet including a water-soluble macromolecule, fatty substances, a water-soluble multivalent metallic salt, sake lees, starch and an outer surface with an aqueous solution of water-soluble alginate to form a water-insoluble coating of said alginate on the outer surface of the droplet; and   contacting said droplet coated with said water-insoluble coating of said alginate with glycerol aqueous solution to form a glycerine coating on the water-insoluble coating of said alginate,   wherein the sake lees derive from any sake selected from a group consisting of Junmai Daiginjo-shu, Daiginjo-shu, Junmai Ginjo-shu, Ginjo-shu, Special Junmai-shu, Junmai-shu, Tokubetsu Honjozo-shu, Honjozo-shu, and Futsu-shu,   wherein the sake lees include amino acid, and   wherein the sake lees are 1% to 10% by weight of the droplet and the starch is 10% to 20% by weight of the droplet.   
     
     
         5 . The method according to  claim 4 , wherein said water-soluble macromolecule is a quince seed mucilage. 
     
     
         6 . The method according to  claim 4 , wherein said water-soluble multivalent metallic salt is water-soluble calcium salt.
