As a kind of herbal medicine, different processing methods have been studied to improve ginseng qualities. However, as a food material, ginseng processing has not been fully studied. The objective of this study was to develop novel food products for ready-to-eat (RTE) ginseng chips with specific flavors through food processing (soaking with different media, pre-heating, steaming, freezing and freeze drying). Changes in chroma, texture, total phenolic contents (TPC), and DPPH radical scavenging activities (DPPH) of novel ginseng product were investigated. Results showed that ginseng treated with most of soaking media obtained significant differences (p < 0.05) in food properties. Typically, significant (p < 0.05) color changes in ginseng chips was found in ginseng treated with black soybean soaking water. An obvious enhancement of total phenolic contents (TPC) and DPPH were found in green tea water. RTE ginseng chips with valueâ€“added and specific flavor were successfully obtained by food processing technology.
