Is it possible to separate proteins as well as sugars and alcohols from rubber tree latex using membrane technology?
Thread Content
The latex of the rubber tree looks like milk, but it contains a large amount of rubber particles (35%) with sizes ranging from 50 nm to 1 um, as well as other particles, and it tends to coagulate easily. Its main components are rubber particles (35%), yellowing agents (10%), and whey (55%). Proteins, sugars, and alcohols are present in whey. Our current idea is to remove large particles using MF and UF, separate the whey, and then selectively isolate the desired proteins as well as other small compounds from the whey. The problem now is that natural latex is a bit viscous, tends to clot into clumps, and can easily cause blockages. Is there any type of membrane suitable for such situations? Will ceramic membranes work?
For dealing with such substances that easily solidify, the best membrane is a ceramic membrane! A little consideration at each step, and by taking things into consideration step by step, we believe this will meet your requirements!
The content of rubber particles is very high (35% + 10%), and the viscosity is also high; it is feasible to use ceramic membrane technology, but the concentration factor is not high, and a considerable amount of water is required for washing. I suggest using a conventional filter press instead, followed by microfiltration membranes (although ceramic membranes can also be used). A large amount of soluble plant proteins will still pass through the ceramic membranes, causing contamination of the subsequent nanofiltration membranes. Moreover, alcohols are unlikely to be retained by nanofiltration membranes, while these membranes perform well in retaining sugars. If it is only at the experimental stage, ceramic membranes combined with nanofiltration can suffice; however, more considerations are needed for industrial production. I’m not sure what the situation is in your case
It is currently in the experimental design phase, with industrial production considered in the future. My current idea is to ultrafilter out the proteins and then concentrate what remains using a nanofiltration membrane. The alcohol compound I want to separate is an inositol analog with a molecular weight of around 200. Is there a better method for separating it using membrane separation? ?
