Soft capsules

which are made by vegetable gum replacing the gelatin as the capsule shell

are called vegetable gum soft capsules.With the deep application of gelatin soft capsule

its disadvantages become more prominent

so it is necessary to find a new capsule material for the development of soft capsule.Currently

vegetable gum soft capsules has made some progress with many patent applications

but few mature products come into the market.Based on consulting a large number of related literatures of vegetable gum soft capsules in recent years

this paper classified five kinds of soft capsule materials which has mature research

including the research status of carrageenan

starch

mannan gum

xanthan gum and sodium alginate

and their gel mechanism and advantages are discussed.Therefore

this article will discuss with the prospect of its application prospects and proposing further research

provide a reference for the development and application of new vegetable gum soft capsules.A variety of excellent performance of vegetable gum soft capsules were mixed to make up for the defects when used alone

thereby expanding the scope of use of vegetable gum soft capsules and improving its performance.
