AI Technical Summary

Technical Problem

The digestion of gluten-containing wheat, barley, rye, etc. in individuals with gluten intolerance may trigger an abnormal autoimmune response, leading to celiac disease and other related conditions. Current treatments mainly rely on a lifelong strict gluten-free diet. However, it is difficult to avoid the presence of gluten and is not easy to implement.

Method used

It uses the enzyme Nepenthes protease, which has high protein and oligopeptide cleavage activity, especially under low pH conditions, and can effectively degrade gluten into non-toxic peptides, thereby regulating patients' gluten intolerance or related diseases. The enzyme can be administered as a food additive or alone to process foods containing gluten, reducing levels of toxic gluten proteins or peptides in the small intestine.

Benefits of technology

By degrading gluten into non-toxic peptides, reducing the autoimmune response caused by gluten, alleviating or inhibiting celiac disease, wheat allergy and other conditions, it provides an alternative treatment method for individuals with gluten intolerance, simplifies dietary management, and improves quality of life.
