Abstract:Study in the craftsmanship of the burdock tea; Through the study of different formula and proportioning modulation to make herbal teas with the best taste and health effects. The main material include burdock, immortality, chrysanthemum, honeysuckle, licorice root, peppermint, hawthorn. The results show that Burdock optimum extraction process is temperature 100 ℃, ratio of solid to liquid 1:80, time 30min, the additive amount of sugar 7%, citric acid 0.02%, β - cyclodextrin 0.2%. Under this condition, the organoleptic quality will be the best. The physical and chemical indicators: light transmittance is 95.3%, soluble solids ≥9%, the content of total flavonoids 0.95%, the content of polysaccharide 3.492%.
