The changes of nutrition in milk treated with different technologies are also determined. Results showed that, 1 higher pressure, longer holding time and more alternative times favour a larger destruction of microorganisms; 2 the combined effect of hurdle technology and pressure on the destruction of microorganisms in fresh raw milk is more effective than only using pressure treatment, among which the effect of ε-polylysine on inactivation of microorganism in fresh raw milk is more effective than that of Nisin with the same concentration of 100mg/L; 3 the whole proteins in milk treated by the different types of sterilization have been detected by SDS-PAGE electrophoresis, and comparing with the whole proteins' electrophoretogram of fresh raw milk, we found that the first spectrum band near the negative pole was disappeared and the colours of the second spectrum band was tint in UHT, pasteurism and 500MPa treated milks, which was suggested that some proteins' subunits were dissociated, but the 400MPa treated milk showed the similar eletrophoretogram with the fresh raw milk; 4 the loss of threonine, VA and VC in high pressure treated milk was more less than those in pasteurism treated milk, in particular threonine and VA were almost retained, and the contents of VB1 and VB2 in the former are also more than that in the latter; 5 high pressure treated milk had longer shelf life than pasteurism treated milk, extending the sale semidiameter of milk.

The experimental results show that the distributions of content and toxicity equivalent quantity of PAHs in raw coal are similar to coal gasification but this compositions and contents are different. The rise of coal rank leads to the decrease of the content and TEQ of PAHs in raw coal and the increase of TEQ during coal gasification, while the content of PAHs emission from coal gasification increases first and then decreases with the increase of coal rank. The total PAHs contents generated in coal gasification of some sorts of coals are higher than in raw coal. The types of PAHs formed in coal gasification include undecomposed PAHs in raw coal, pyrosysthensis PAHs, and radical polymerization PAHs at high temperature.
