Approved situation and problems of the Spirulina health foods

The approved health food products in China were analyzed from the following five aspects: the number of approved products, the use of raw materials, the claim of health function, the distribution of dosage forms, and the index of signature ingredients. It was found that almost all Spirulina powder was the primary processed product, and the homogeneity was serious. Moreover, the characteristic components were different from those of β-carotene and phycocyanin specified in the record. Based on these problems, the healthy development of health food industry should be promoted by broadening the idea of product research and development, and then improve the synergistic effect of registration and filing.
