Compared to gelatin capsules, HPMC capsules, in addition to being a plant-based source, also have relatively low water content, high stability over a wide temperature and humidity range, no cross-linking, and are especially suitable for hygroscopicity formula. HPMC capsules are plant-derived capsules. The water content of the hollow capsules is 4-6% and can reach 3% with special requirements. The water content is low, does not easy to become brittle, has good toughness, and has good chemical stability. Not decremented during storage. The main plant sources are cotton, bark, etc. The vegetarian capsule has a unique anti-acid polymer property, which can resist the decomposition of gastric acid. When it leaves the acidic environment and reaches the intestinal environment with a pH of 5.8, it begins to decompose 20 minutes later. It is therefore more suitable for carrying probiotics, enzymes, and many other sports nutrients.

    The starch vegetable capsule is a new type of capsule that uses natural vegetable starch as the main raw material and does not use animal-derived ingredients. Starch plants are collected, washed, pressed, and purified to obtain plant starch. The main plant sources are cassava, corn, potatoes, etc. Tapioca starch is mainly amylopectin, its water content is similar to that of gelatin, and it has good water resistance and oxygen barrier rate. Provides good protection for both powder and liquid products, just like gelatin.
