Abstract： In this paper， the vacuum freeze-drying method was used to process the ready-to-eat artichoke sprouts， and the processing technology of artichoke artemisia sprouts was optimized through single factor and response surface tests. The results showed that the optimal processing technology of vacuum freeze-dried artichoke buds was 18 min for color preservation， 70 ℃ for blanching temperature， and 44 h for vacuum freeze-drying.
