Abstract: The chemical composition of silkworm pupa was outlined.The extraction and refining technology of effective ingredients such as pupa protein,pupa oil and pupa chitin were introduced in detail.Meanwhile,it was deeply discussed about the physiological function of silkworm pupa effective ingredients and the development prospects and utilization status of related products which were widely used in food,medicine,chemical,biological or other areas.Finally,the problems and solutions that existed in the resource utilization of silkworm pupa were put forward as a theoretical basis to realize the industrialization of silkworm utilization.
