Optimization of Processing Technology of Honey-fired Polygonum perfoliatum by Orthogonal Test / 中国药房

ABSTRACT

OBJECTIVE:To optimize the processing technology of honey-fried Polygonum perfoliatum. METHODS:The pro-cessing method of honey-fried P. perfoliatum was optimized by L9(34)orthogonal test with the contents of effective component quer-cetin and water-soluble extract as comprehensive evaluation index,with the amount of honey,moistening time,baking temperature and baking time as investigating factors. RESULTS:The optimal processing technology was as follows as 30% honey,moistening for 120 min,baking for 50 min at 70 ℃. In verification test,the content of quercetin in 3 batches of honey-fried P. perfoliatum was higher than 0.05%,and the content of water-soluble extract was higher than 25%(RSD<2.5%,n=3). CONCLUSIONS:The optimized processing technology is stable and practical,and can provide reference for standardizing the processing technology and quality control of honey-fried P. perfoliatum.
