The different processes of leaching and spray drying technology to extract gum from flaxseed were conducted.

Glossy privet fruit was extracted in 95 %vol edible alcohol by ultrasound,the optimum leaching program was screened out by HPLC with leaching amount of oleanolic acid as the index.

Effects of Water Extracting on Potassium Content in Flue-cured Tobacco Leaves;

The results showed that hot water was an ideal solvent for glutathione,extracting,and the extraction procdure was optimized by single factor and orthogonal experiments,the optimal extraction condition are extraction time 12 min;the ratio between mater and solvent 1∶9;the suitable extraction temperature 95 ℃ and stirri.

The odd factor test' results indicate:temperature,alcohol concentration,pH have notable influence to extracting pigment,pectic enzyme,ultrasonic,microwave can improve extracting effect,but the impact is not prominent.

The production techniques included grinding,lixiviation,filtration,blending a nd sterilization.

Combing with oxygen or reducing substances in grape juice, SO2 not only has theeffect of antioxidation but also can improve acidity and the efficiency of Lixiviation, which has good effect on color and aromaof grape juice.

Bee pollen was used as raw materials and the effects of different lixiviating conditions on lixiviation rate of free amino acids and flavonids from bee pollen were investigated.
