In the course of establishing standard operating procedure, The temperature, time , the feasibility without decorticating and efficiency were investigated when alliinase was deactivated used a dry heating apparatus in tunnel type, but the efficiency can be achieved less than 70%, need to be improved; The reformative cribriform plate has been proved to be good in practice result in pulping enzyme-deactivated garlic without dehulling; The extraction efficiency achieved more than 90% when volumic ratio of 20% alcohol and water is 3 I 1 and 2:1 was adopted to extract alliin two times respectively; During exact filtration, the ratio of diatomite in precoating and filtration was 3% and 1% respectively, the losses of alliin adsorbed by diatomite in extraction solution were not remarkable. In the stage of alliin isolation by ion exchange resin, three simple and sensitive detected measures were successfully adopted to control the whole process; the efficiency of alliin isolation was similar to laboratory results; The alliin yield was over 50% in acidic fractions and the purity quotient of alliin achieved above 50% after drying; Furthermore, the phenomenon was found that losses of alliin were seriously affected by the temperature and time periods in concentration.

Production of Creping paper and handchief paper increases very rapidly, which ask for good sopping properties, softness, appearance and strength.what more, the thin paper and straw fiber instead of cotton fiber will be development trend for decreasing cost. Therefore, we do a lot of studies on the raw material, process, equipment and chemicals in order to solve three practical problems. Firstly, decreasing beating degree, shorting beating time and saving energy. Secondly, ensuring papermaking normally and improving productive. Finally, increasing the paper brightness, softness and sopping properties.
