Optimization of explosion puffing drying for high-value yellow-fleshed peach crisps using response surface methodology

Response surface methodology (RSM) was used to comprehensively evaluate the pilot scale nonfried explosion puffing drying (EPD) conditions for developing high-value yellow-fleshed peach crisps. The independent variables were different levels of vacuum drying temperature, vacuum drying time, and puffing pressure difference. The responses were crispness, total color difference (ΔE), total carotenoid content (TC), and DPPH radical scavenging...
