Its mainly procedures include: extraction of mushroom, production of soy sauce, making of chili sauce, production of sauce glue, seasoning and sterilization ect.

Compared three methods that extract oligosaccharides from carrot,the best technology is: Ethano-Methanol extraction.

Experiment on refinery sludge treatment by solvent extraction;

Herein, solvent extraction could be used to take out the structure templates from zeolite pores because the interaction between skeletal Zr-O-Zr structure and PEO surfactants is very weak.

Five methods in solvent extraction for separating aromatics in China and abroad were introduced, including Udex, Sulfolane, Arosolvan, DMSO and Formex processes.

Revamping of atmospheric naphtha aromatics extraction unit and process parameters optimization;

Causes and protective countermeasures for corrosion of aromatics extraction system;

In order to study influence of different factors on coal extraction yield,temperature,irradiation time,the ratio of solvent volume to coal mass and granularity of coal were discussed for Shenfu coal under microwave-assisted extraction(MAE) using tetrahydrofuran(THF),ethanol and methanol as solvent.

The results showed that little xylan absorbed on fiber or carbohydrate linked to cellulose was removed out during xylanase pretreatment stage and these carbohydrate mainly were removed out during alkaline extraction stage, and this would lead to an obvious decrease in special absorption coefficient.

The effects of xylanase AU-PE89 treatment combined with chelating and alkaline extraction on HD bleaching of NaOH-AQ wheat straw pulp, was investigated.
