The invention discloses an empty
capsule and a soft
capsule based on
modified starch. The empty
capsule is prepared from the following raw materials: 40 to 90 parts of the edible
modified starch, 3 to 30 parts of gelatinizer, 2 to 20 parts of
plasticizer, 2 to 20 parts of
plant fiber, 10 to 50 parts of deionized water, 1 to 6 parts of colorant and
opacifier, and the empty capsule is prepared by the following procedures of mixing, glue dissolving, degassing, dipping,
drying, shell pulling and
cutting; the soft capsule is prepared from the following raw materials: 30 to 60 parts of edible
modified starch, 8 to 40 parts of gelatinizer, 6 to 20 parts of
plasticizer, 6 to 20 parts of
plant fiber, 20 to 60 parts of deionized water, 1 to 6 parts of colorant and
opacifier, and the soft capsule is prepared by the following procedures of mixing, glue dissolving, degassing, dipping,
drying, shell pulling and
cutting. According to the empty capsule and the soft capsule, a series of problems of long disintegration time,
fragility, poor
water retention and the like of an existing
starch capsule and soft capsule are solved, and
gelatin is replaced by
starch, so that the empty capsule and the soft capsule have the advantages of low cost, stable chemical properties, difficulty in growing of
microorganism, difficulty in getting fragile, difficulty in crosslinking and the like and are suitable for long-term storage.
