Abstract: Objective: To evaluate the difference and similarity of nutritional composition of two types of commercially available Maca tablets, processed using maca root tubes grown in Peru and Lijiang in Yunnan, respectively. Methods: The nutrients such as protein, amino acid, fat, fatty acid, crude fiber, vitamin and 10 kinds of mineral substances in both maca tablets were subjected to comparison according to the international standards. Results: Similar nutritional composition and contents in both maca tablets were observed. However, Lijiang Maca tablets revealed significantly lower contents of fat and iron than Peru maca tablets, and Peru maca tablets had higher levels of unsaturated fatty acids and arginine. Conclusion: Maca has a high nutritional potential so that it can be introduced and further exploited.

Key words: Lijiang Maca tablet, Peru Maca tablet, nutritional composition, comparative analysis
