Optimized hot-air drying enhances gastrodin content and antioxidant activity in Gastrodia elata: insights from chemical and microstructural analyses
{{output}}
Optimizing the drying process for Gastrodia elata (G. elata) increases the content of its key bioactive compound, gastrodin (GAS). This study primarily investigated how hot-air drying conditions (90-160 °C for 4 h and 150 °C for 1-5 h) affected the GAS conte... ...
