Abstract
The aim of this research was to assess the quality of the cochineal(Dactylopius coccus Costa) which cultivated in middle area of Yunnan Province.The bulk density,insect numbers per gram,water absorption and expansivity,as well as main chemical composition of the cochineal that cultivated in middle area of Yunnan Province were compared with the cochineal cualtivated in Peru.The results showed that significant differences exist between cochineal cultivated in middle area of Yunnan Province and in Peru,except bulk density.Cochineal cultivated in middle area of Yunnan Province can be also used for making carminic acid.
