I understand, the purpose of their cultivation was to extract papain for marketing to pharmaceutical companies. Papain possesses enzymes capable of breaking down animal and even vegetable protein bonds, which is why it is synthesized as a softener. I had knowledge of the softening capacity of papaya milk (papain); however, I did not know about the extraction process that you explain to us.
Very interesting and valuable information you provide, especially because you have experience in papaya cultivation and papain extraction.

Your valuable comment enriches the content of this synthetic post. Thank you for the intervention and substantial comment.
