Snail mucous has many advantages, what is the best way to extract it without changing its composition?

Snail mucus is possible to extract. Allow snails to move about and it releases its mucus and which can be dried and collect thereafter.

Similar to collecting mucus on the paper, collect it on a moving surface, so that the concentration of mucus can be increased at a particular place.

Secondly, the silica or some other inert material powder can be spread over which snails will crawl. The powder can be collected later and used for mucus extraction.

Collect the mucous from a sheet of paper and dissove it with ethanol of various pecentages.
