in the present invention , the content which can be seamless - encapsulated is not limited to a specific one and can be anyone which can become a liquid under heating and is ejected from a nozzle . the process of the present invention can be effectively applied for that which is a liquid at a normal temperature and has hydrophilic nature . the typical content is not limited to a specific one and examples thereof include various pharmaceutical solutions , foods , cosmetics , flavors , industrial chemicals and the like . the film substance of the seamless capsule used in the present invention is not specifically limited and suitable one can be obtained by subjecting ( a ) gelatin , and , optionally ( b ) water - soluble polyhydric alcohol or water - soluble derivative thereof to a gelation treatment . gelatin , or the water - soluble polyhydric alcohol or water - soluble derivative thereof having the same grade as that of which is used for producing a conventional capsule may be employed as it is . the water - soluble polyhydric alcohol or water - soluble derivative thereof is not specifically limited and examples thereof include glycerin , polyglycerin , sorbitol , ethylene glycol , polyethylene glycol , propylene glycol , polypropylene glycol , ethylene oxide - propylene oxide copolymer , oligosaccharide , sugar ester , glyceride , sorbitan ester and the like . the amount of gelatin to be used is normally 50 to 90 % by weight based on the total weight of the capsule film . further , the amount of the water - soluble polyhydric alcohol or water - soluble derivative thereof is 10 to 30 % by weight , preferably 15 to 25 % by weight based on the total weight of the capsule film . in the seamless capsule of the present invention , a low fatty acid of sucrose is present between the above - described film and content which is the hydrophilic substance . the lower fatty acid ester of sucrose is a compound having a hydrophilic and lipophilic group , which has an action similar to that of a surfactant , and it is generally compatible with the above - described hydrophilic substance and film substance . examples of the lower fatty acid , which esterifies sucrose , include a fatty acid having 2 to 6 carbon atoms ( e . g . acetic acid , butyric acid , caproic acid , etc .). the suitable lower fatty acid ester of sucrose is saib ( sucrose acetate isobutylate ) which is commercially available from eastman chemical products , inc . fig1 illustrates one embodiment of the nozzle part of an apparatus which is suitable for producing the seamless capsule of the present invention . a capsule content 4 which is supplied into a nozzle part is extruded from an inner nozzle ( first nozzle ) and a lower fatty acid ester of sucrose 5 is extruded from an annular pore tip part of an intermediate nozzle ( second nozzle ) 2 and , at the same time , a film solution for a seamless capsule 6 is extruded from an annular pore tip part of an outer nozzle ( third nozzle ) 3 , and then a three - phase composite jet thus obtained is ejected into a cooling solution 8 to obtain a seamless capsule 7 of the present invention . in this case , when the content jet 3 is a two - phase jet , a triplex soft capsule is obtained and , when it is a three - phase jet , a quadruplex soft capsule is obtained . similarly , a desired multiplex soft capsule is produced . the filler is liquid and , therefore , by providing a suitable vibration to the composite jet flow using a vibration means , dropping of the jet flow may be improved , whereby , encapsulation is easily conducted , which results in uniform particle size . the seamless capsule thus produced as described above may be dried as it is and then washed . according to the present invention , a seamless capsule containing an hydrophilic substance , particularly an aqueous solution as a content can be easily obtained by a dropping method . a lower fatty acid ester of sucrose protects the hydrophilic substance to avoid contacting it with the film . since the fatty acid ester of sucrose is transparent at a normal temperature , it is extremely easy to design a color of the seamless capsule . the following examples further illustrate the present invention in detail but are not to be construed to limit the scope thereof . by using water ( 100 % ) as a solution i , a capsule of 4 . 2 mm φ was produced . ______________________________________ ( formulation 1 ) ingredients amount (% by weight ) ratio (%) ______________________________________solution i : water ( 100 %) 100 70solution ii : sucrose fatty acid ester 100 20 ( saib ) solution iii : gelatin 20d -
