A process for hydrolyzing products with enzymatic activity remaining in peptone solutions after mucosa hydrolysis is provided along with a process for preserving mucosa tissue. Broadly, the processes are carried out by hydrolyzing mucosa tissue according to conventional heparin manufacturing processes wherein an excess quantity of proteolytic enzymes is used. The resulting peptone solution is then contacted with proteins or protein-containing materials in order to hydrolyze the proteins. In another embodiment, mucosa tissue is preserved by mixing it with a preserving agent selected from the group consisting of hydrogen peroxide and phosphoric acid. The product preserved by hydrogen peroxide is low in ash, stable for at least a week, and has a reduced odor.
A preserved mucosa tissue product formed by heating a quantity of mucosa from about 50-105° C. and contacting the mucosa tissue with a preserving agent selected from the group consisting of hydrogen peroxide in an amount of less than about 1% weight by weight of mucosal tissue and phosphoric acid in an amount sufficient to reduce the pH of the tissue to about 2 to 4, wherein the preserved mucosal tissue has an ash content of less than about 10% by weight.
