Technology Description:
Bio-fortified sweet potato cultivars are recognized as healthy foods due to their abundance of health promoting compounds, essential minerals and dietary fiber. Vacuum frying is a promising food processing technology that preserves nutrients, colour, texture and flavor in ready-to-eat snacks. It involves frying of products under controlled conditions at an ambient temperature and pressure for a specific period of time to give higher-quality products. Another advantage of vacuum frying is that it reduces the development of acrylamide formation during the frying of starch-rich products such as sweet potato chips.
