摘要：[Objective] The aim was to research property of maca and three plants＇ powders and process parameters of compound maca direct compression. [Method] Based on analysis data from SAS, bulk density, tap density, angle of repose and swelling of powders were studied as per single factor method and orthogonal exper- imental design. [Result] The test indicated that fillibilities of plant A and B, and maca powders are better and flowability plays an important role in fractional close of compound maca powder; plant A and B powders have a significant effect on bulk density of maca （P=0.0125）, an extremely significant effect on swelling volume ratio （P=0.008 9） and little effect on tap density （g/ml）; the optimal process condition of compound maca powder is as follows： A at 0.15 share; B at 0.10 share; C at 0.05 share; the optimal swelling volume ratio is at 2.459. [Conclusion] The technology is reasonable in formulation and satisfactory in fillibility, swelling ability, flowability, and it could serve as theoretical basis for the industrial production of maca tablets.

摘要：The orthogonal experimental design was used to optimize the formula of maca lozenge and explore the preparation techniques and product property of maca lozenges. With the sensory evaluation of maca lozenge as the indicator, L16 （44） orthogonal design graph was used to select the optimal techniques, and to investigate the stability, heavy metals and microorganisms contents in the tablets. The optimal formula was 80% of maca power, 12% of Rhodiola rosea powder, and 6% of Angelica sinensis powder, where the comprehensive sensory index reached 246. Moreover, under the optimal conditions, various kinds of heavy metals contents were in consistent with the GB164740 standards, and there was no significant change in color, size, friability, and disintegration time, as well as microorganism content during the 12-month preservation. With simple, easy and reliable technique and quality control method, the process study had obtained the national patent process （patent number： ZL200810233796.X）, and the contents of heavy metals and micr6organisms laid foundation for the quality standard.
