ABSTRACT: The wheat seedlings were dried in different ways, and the effects of different drying conditions on their bioactive components were explored, and an optimum drying process was obtained. The contents of total chlorophyll, polysaccharide, flavonoids and polyphenols were determined by colorimetry.
The results showed that the highest total chlorophyll content was 82.33 mg/100 g when microwave drying equipment was 560 W; the highest polysaccharide and polyphenol content was 19.87 mg/g and 5.80 mg/100 g when oven drying temperature was 90 degrees C; the highest content of flavonoids was 5.29 mg/100 g when microwave power was 420 W; conclusion: the best drying condition was oven drying temperature 90 degrees C, microwave drying. The power is 420 W.
