Guest guest Posted May 4, 2004 Report Share Posted May 4, 2004 I am interested in the process of making liquid silk or silk powder from tussah fibers. How is it done? Any information is appreciated.

Guest guest Posted May 4, 2004 Report Share Posted May 4, 2004 Thanks for the response Maurice. I think I need to ask my question a different way. I use silk protein in my soaps by adding tussah silk fibers to the lye solution. This is complicated by the fact that I make cold process milk soaps and have not figured out a way to dissolve the silk in the lye/milk solution which adds extra steps and messes with my process. So I was hoping for a way to make liquid silk myself because I prefer to use tussah (this is an environmental thing LOL) So my real question is how do I as a kitchen soapstress make my own hydrolized silk in some sort of organized way?

Guest guest Posted May 5, 2004 Report Share Posted May 5, 2004 Aliza, You can keep using the fibers, just add your milk differently ... dissolve your silk fibers in lye made with half the liquid, (if you are using powdered milk, make double strength milk for the other half of the water, and add the chilled (near frozen) milk slowly at light trace. If using fresh milk, I would use 1/2 of the water to make lye, dissolve the fibers, and add both the (chilled .. almost frozen) milk and the lye, at the same time but at a very slow trickle till it is all incorporated.

Guest guest Posted May 5, 2004 Report Share Posted May 5, 2004 Aliza, When you say you want to hydrolize your silk, you are refering to breaking down the larger silk protein into smaller peptides or amino acids. Biochemists do this by dissolving the protein in concentrated hydrochloric acid (HCl) and then heating that. This breaks the bonds between the amino acids in the protein. It is something too dangerous to do at home however. The other (safer) way is to digest the protein with enzymes. These enzymes however are very specific for which bonds in the protein they will break. You might be able to purchase some enzymes at a reasonable price from a chemical supply. You could use trypsin or carboxypeptidase or other proteases. Each of these would require specific conditions to work in however. Again though, this might be more than what you want to attempt.
