Beet pulp pectin resin decolorizing technology and the characteristics of different molecular weight decoloring pectin research:
palm oil mill (http://www.palmmill.com) mainly from the following several aspects to study: beet pulp pectin of the beet pulp pectin by macroporous tree fat decolorization, comparison, decoloring process of suspension layer and precipitation affect the structure and properties of pectin, pectin decolorization of beet pulp using ultrafiltration method classification, molecular weight of ultrafiltration method for four different molecular weight of beet pulp bleaching pectin structural characteristics, rheology, emulsification and oxidation resistance were compared.The main research contents and conclusions are as follows: first, beet pulp pectin decoloring process research on decoloring rate and recovery rate as an index, select the D101 resin decolorization study, the results show that the static, in the pH is 1.8, the dosage of resin is 1 g/ml, 25 decoloring temperature of 35 ℃, decoloring time for 60 min, decoloring rate and recovery rate was 74.36% and 74.36% respectively;Dynamics, the flow rate of 2 bv/h, pectin degree of hydraulic hammer was 2.5 Bx, capacity reaches 10 bv, decoloring rate reached 80.99%.Desorption conditions: 70% ethanol, velocity of 2 bv/h, desorption temperature is 25 ℃.Desorption four times, the capacity of 10 bv, decoloring rate reached 68.08%.Second, deodorization process (http://www.palmmill.com/News/108.html) of beet pulp pectin qualitative change before and after comparing the decoloring work respectively art on the original pectin, the pectin suspension layer and the influence of the sediment layer properties, the results showed that the decoloring, esterification degree of pectin, galacturonic acid content, higher molecular weight, content of ferulic acid and neutral sugar content is lower, no changes in.Suspension layer pectin precipitation than pectin nature good, decoloring, pectin shallow color,...
