Feasibility and opportunities for Peruvian purple corn in Australia

Summary

Peruvian purple corn is a variety of maize that originated in Peru under the Incan Empire. It is currently used for food (both traditional and nontraditional), beverages (nonalcoholic and alcoholic), as a natural food colourant (especially in the EU where use of artificial colourants is restricted), and as a health product (cardiovascularrelated disease). It is becoming increasingly popular in the United States, Europe, and Japan, and more recently in southeast Asia with the development of purple waxy corn. Peruvian purple corn has been claimed to have an extremely high concentration of anthocyanin, with an antioxidant capacity approximately four times that of blueberry. The subsequent dual use of purple corn as a colourant and health product is therefore fortuitous. There is currently no purple corn industry in Australia. The current proposal aims to undertake a feasibility study into the potential and opportunities for developing purple corn products in Australia, and what limitations may be needed to be addressed.

Objective Summary

A domestic and international audit of production levels, market value and locations. A literature review of research undertaken in relation to purple corn. A scan of demand for purple corn products, and potential scale and location of markets (domestic and overseas). Investigative research assessing access to Peruvian corn germplasm, ability to be grown in Australia, and anthocyanin levels produced relative to other anthocyaninproducing products. Identification of potential impediments to production and profitability. Identification for next steps towards commercialisation, including next steps for research.
