PREPARATION OF LOW METHOXY PECTIN,APPLICATION AND ADVANCE IN ALKALINE DE-ESTERIFICATION PROCESS

The paper generally introduced the types of pectin,resource, condition and mechanism of pectin gelation.We contrasted the four common de-esterificate methods and mainly discussed the application,advance in Alkaline de-esterification process at home and abroad and how to reduce β-elimination reaction.Factors affecting the production of low methoxy pectin are also generally discussed.As the quality of life improved,the need of Low methoxy pectin will also increase dramatically.Raw material of high methoxy pectin is very aboundant at home,with the technical of de-esterification fully developed,it can take us huge socialeconomic retures .
