Wecan(Weishi) Biological Science & Technology Co., Ltd., as an expert in the integration of micro-capsules and synthetic nutrition supplements, is specialized in the manufacture of various encapsulization vitamins (VA.VD3.VE.VK) and unsaturated fatty acids(.DHA.AA) as well as synthetic nutritional supplements. We boast top technology with independent intellectual property rights, and are equipped with domestic unparalleled production lines of micro-capsules and premix compounds. This technology, so far the most effective method for products with biological activity and easily oxidized, features secondary microencapsulation under the protection of low temperature and inert gases. Double microencapsulation can keep the status of micro-capsules while solubilizing products, which can ensure the stability of active ingredients. This technology can meet the needs of such production process as wet method, dry method, high temperature sterilization, shirring and high-temperature high speed mixing etc.
