Since the United States invented the plant capsule in 2000, it has developed rapidly in Europe and the United States, and the United States plans to increase its market share to 80 percent in the next few years. So what is the advantage of plant capsules, can be so high evaluation in the international community?
First of all, the raw materials are different, the main raw material of plant capsules is medicinal hydroxypropyl methyl cellulose (HPMC), is the most abundant natural polymer in nature, is extracted from the sea or land plants by physical methods; Gelatin capsules are medicinal gelatin. Collagen from skin, tendons and bones of animals (mainly pigs, cattle and sheep) is extracted by chemical methods.
HPMC in plant capsules is stable in nature (with chemical reactions in air and water), and will not cross-link with some drugs. It has wide adaptability, stable drug release speed, complete dissolution, more significant effect and small individual differences. HPMC made of shell still has a natural concept, the production process does not need to add any preservatives; Gelatin capsules are easy to breed breeding bacteria and microorganisms, and preservatives need to be added in the production process (resulting in the residue of paraben preservatives, epoxy ethanol, chloroethanol, etc.).
Plant capsules are not brittle under low humidity conditions, but can still keep the capsule shell stable under high humidity conditions. The storage conditions are broad, and the temperature between 10-40 ℃ and the humidity between 35-65% will not soften, deform or harden and become brittle. Gelatin capsule under low humidity conditions of dehydration hardening, high humidity conditions of capsule adhesion, storage and transportation conditions are relatively strict. HPMC has metabolic inertia, is not absorbed in the body, directly exclude in vitro, plant capsules are not easy to grow microorganisms, long-term placement will not decompose metamorphism, usually valid for 36 months.
Herbal capsules derived from natural plants are the best choice for vegetarians and religious believers.
The identification method of plant capsules is also very simple. When roasted by fire, you can smell the burnt cotton wool, while the smell of gelatin capsules is like burning hair.
