There is.

Further, as a method of improving the productivity of the above method, a method of forming droplets by vibrating a nozzle (for example, Japanese Patent Laid-Open No. 59-112,831), a method of jetting a jet liquid from a cylindrical orifice in a cooling liquid. Extrusion, a method of creating droplets by vibrating a ring body surrounding this jet stream (for example,

Chemical gelation refers to gelling with a chemical gelling agent such as a polyvalent metal salt, a saccharide, a sugar alcohol, an organic acid, an ester of an organic acid, or tannin. Gelling at a low temperature of 10 ° C. or less.
