Abstract

The invention discloses pullulan hollow capsules. The pullulan hollow capsules are prepared from the following components in parts by weight: 38 to 50 parts of pullulan, 30 to 35 parts of soybean protein isolate, 0.88 to 1.34 parts of gella gum, 1 to 3 parts of glycerin, 0.1 to 0.6 part of sodium sulfite and 0.05 to 5 parts of hydrophobic fatty acid. The invention further discloses a preparation method of the pullulan hollow capsules. The pullulan hollow capsules have the advantages that the pullulan hollow capsules are easy to produce and stable in quality; the hydrophobic fatty acid and Na2SO3 are added, the strength of a soybean protein isolate film can be increased and the water absorbing performance of the soybean protein isolate is reduced, so that the storage stability and environment adaptability of the hollow capsules can be effectively improved.

Description

technical field [0001] The invention relates to the field of hollow capsules, in particular to a pullulan hollow capsule. Background technique [0002] At present, there are mainly three types of non-animal hollow capsules, one is capsules made of water-soluble cellulose derivatives as the main raw material; the other is capsules made of starch as the main raw material; and the other is pullulan as the main raw material. Empty capsules prepared from raw materials. Among them, the first type of capsules has the defects of unstable disintegration, high oxygen transmission rate and poor appearance; the second type of capsules has the defects of poor friability and inability to hold liquid; Capsule-like has the advantages of low oxygen transmission rate, good transparency, and short disintegration time. [0003] However, during the preparation process of the pullulan hollow capsules, the viscosity of the glue solution is too high, stirring is difficult, and the manpower and ma...
