1.2 experimental method
1.2.1 sesame samples are prepared to remove sesame seeds and remove impurities such as sand and dust. In order to simulate the state of newly harvested sesame, 1000 g sesame seeds were sprayed with 140 mL deionized water evenly, sealed in plastic bags and placed in a constant temperature and humidity box at 4 C for 48 hours, shaking evenly every 5 hours, so that the moisture was fully absorbed into the sesame interior, and the reduced sesame samples with moisture content of 11.4% (wet base) were obtained.
