Description

Technical Field

[0001] The invention relates to the technical field of soft capsules, and in particular to an opaque chewable soft capsule shell and a preparation method and application thereof. Background Art

[0002] Titanium dioxide (TiO2) is considered to be the whitest inorganic pigment. The important properties of titanium dioxide are its thermal stability, opacity and bright white color, which are particularly attractive in improving the visual appeal of products. It is not only used in the food field, but also in soft capsules to achieve white and light-shielding effects. Today, titanium dioxide is officially banned throughout Europe in 2022 and is no longer authorized as a food additive, which has forced more companies to change their original product formulas and develop or find new natural titanium dioxide substitutes.

[0003] For companies looking for alternatives to titanium dioxide, there is no one-size-fits-all substitute and each product has different properties that require exploring different formulation options.

[0004] Therefore, a white opaque raw material with properties that can replace titanium dioxide is needed.

[0005] Based on the literature review and summary of the research progress of titanium dioxide alternatives on the market, this experiment preliminarily selected a white opaque raw material to replace titanium dioxide. Using rubber whiteness, rubber stability, and pelletizing state as evaluation indicators, a raw material was screened out that can coexist with the gelling agent for a long time in air, water, and light environments, is not easy to react, and is not prone to yellowing and fading of the soft capsule material. It is beneficial to the color stability of gel candies, while meeting the whiteness and light-shielding requirements of the rubber. Summary of the invention

Comparative Example 1 does not add zinc oxide, calcium carbonate, and tricalcium phosphate, respectively, and the whiteness is low, and the stability is general. Comparative Example 2 does not add rice starch, and the whiteness is good, but the stability is poor. Comparative Examples 3-5 add titanium dioxide, titanium dioxide compounded zinc oxide, calcium carbonate, and tricalcium phosphate, titanium dioxide compounded rice starch, although the whiteness is good, the stability is poor, and Comparative Example 6 does not add sunscreen, no whiteness, and the stability is general. Without adding one of natural starch compounded zinc oxide, calcium carbonate, and tricalcium phosphate, the whiteness and stability of the capsule skin deteriorate significantly, and the compounding is adopted, and the stability effect of the capsule skin is remarkable.
