Answer 1

This paper adopts steam distillation about fresh coriander stem leaf for water extraction,change under different conditions,such as extracting temperature,extraction time,extract PH,reactant ratio,the reaction time,extract,such as the dosage of factors to determine coriander water extract remove effect of nitrite ability; And establish four factors 3 levels of orthogonal experiments and analysis and find coriander water extract remove nitrite,the optimum condition of the experiments show that,coriander water extract in reactant ratio 10g / 100 ml extraction temperature 90 ℃,and extracting time 90min,extract dosage 15ml conditions 50.23 + 3% of clearance.Results show that the water extract chopped coriander sodium nitrite have good clear ability,to further study chopped coriander role has an important significance.
