Seeing purple

Purple sweet potatoes and other vegetables selected for high pigment content could be an increasing source of natural food colorings in the future, providing alternatives to synthetic pigments and those extracted from cochineal insects. The antioxidant properties of the vegetable colorants could also have health benefits, while the byproducts such as starch and fibre can be used in many others ways.

Space research provides hints for earth
Scientists developing methods for growing food in space have found that sweet potatoes can be trained in a compact vertical arrangement without sacrificing yield, provided the main shoot is retained. Side shoots can be trimmed away, while the main vine is wound around cylindrical or conical cages. The researchers say that hormones produced at the shoot tip stimulate root development. They also say that sweet potatoes are a relatively unfussy crop, making them ideal candidates for the "generalized-growth environment" likely in future space agriculture.

New Qld sweet potatoes to revolutionise market
Queensland scientists are working on new sweet potato varieties with new colours and flavours, enhanced nutritional content and a fatter and more consistent shape. Vigour and resistance to pests and diseases will also be sought-after features. Currently, the orange 'Beauregard' variety makes up 95% of Australian production. Purple and white varieties are also sold, but the season is short. The Department of Employment, Economic Development and Innovation expects their new sweet potatoes to become available in marketplace in the next couple of years.
