Advanced technology of Food Engineering


Super/sub-critical fluid extraction technologies are our specialty, and they are widely used in many relevant research field. In our lab, these technologies are mainly used in the following respects.

1.We use these technologies to extract natural active substance, such as pigments from kelp, volatile oil from Lonicera Japonica, shrimp oil and astaxanthin from euphausia pacifica.

2.Subcritical fluid extraction has been successfully used as a sample pretreatment method in the residue analysis, which including sex hormones, PAH (polycyclicaromatichydrocarbon) and PCB (polychlorinated biphenyl). In the near future, the applicability of this method used for other persistentpollutant will be investigated.

3.We are studying the bactericidalperformance of the supercritical CO2.

4.We are considering using supercritical fluid technology to preperation specific material, such as nanometermaterials

The advantages of super/sub-critical fluid extraction technologies are as follows:

high extraction efficiency,fast, green and easy to operate.
