A leather mildew preventive with nuclear-sheel structure was prepared by complex coacervation,where turpentine is the core material and the mixture of gelatin and gum acacia is the wall material.

In the presence of gum acacia, cadmium reacts with iodide and rhodamine 6G to form an ion--asso- ciation complex in 0.

The influence of hydrolysis time、temperature、acid concentration and solid to liquid ratio on xylose、arabinose and acetic acid concentration are assessed by single factor.

But in the process of ion exchange, xylose molecular is easily converted into arabinose because of catalytic isomerization, which results in the decrease of its purity and difficulty of crystal.

Objective To establish a HPLC-ELSD method for the determination of arabinose.

The application of arabic gum in food industry;

Study on compound of carrageenan and arabic gum and its application in low temperature ham;

Microencapsulation of proanthcyanidins was investigated:arabic gum and maltodextrin were used as wall material,among which the content of arabic gum is 40%,the ratio of core substance to wall material is 30% and the content of the slurry is 20%.

The preparation technology of Artemisia oil microcapsule was studied by complex coacervation method with gelatin and acacia.

Econazole nitrate microcapsule was prepared by complex coacervation with gelatin-acacia as the coating material,Span60 as emulsifier and glutaraldehyde as cross-linking agent.
