Study on the drying methods of wine-processed Cornus officinalis based on the contents of multi-index components
To investigate the effects of different drying methods on the index components in wine-processed
Cornus officinalis
so as to optimize drying method.
METHODS
2
After processed with wine,
C. officinalis
decoction pieces were dried with different drying methods (blast drying, far infrared drying, microwave drying, freeze drying, sun drying, shade drying and combined drying). The contents of 5 components such as gallic acid in wine-processed
C. officinalis
were determined by high-performance liquid chromatography. The contents of total flavonoids in wine-processed
C. officinalis
were determined by chromogenic method. Analytic hierarchy process was used to evaluate the effects of different drying methods on the contents of components in
C. officinalis
.
RESULTS
2
The contents of gallic acid, 5-hydroxymethylfurfural, monoside, loganin, cornuside and total flavonoids in 22 batches of wine-processed
C. officinalis
were 1.043 8-1.563 8, 0.648 5-2.358 8, 5.031 0-10.305 7, 6.681 2-7.534 2, 0.986 5-1.148 8 and 33.657 2-50.741 5 mg/g, respectively. The comprehensive scoring results of analytic hierarchy process showed that the comprehensive score of each component in
C. officinalis
dried by microwave at 75 ℃ was higher, followed by blast drying at 60 ℃ and far infrared drying at 60 ℃.
CONCLUSIONS
2
The wine-processed
C. officinalis
could be dried by microwave drying at 75 ℃, blast drying at 60 ℃ or far infrared drying at 60 ℃.
