Title: John E Walker: Innovator in Meat Tenderization

Introduction

John E Walker is an accomplished inventor based in Framingham, MA (US). He is known for his innovative work in the field of meat tenderization. His contributions have significantly impacted food processing techniques, particularly through the use of enzymes.

Latest Patents

Walker holds a patent for a method of meat tenderization utilizing a proteolytic enzyme derived from the microorganism Trichoderma reesei. The patent, titled "Meat tenderization with a proteolytic enzyme from Trichoderma reesei," describes how meat can be tenderized by adding a specific enzyme obtained from the strain MCG 80. This enzyme, an aspartic acid protease, exhibits proteolytic properties similar to the animal protease, Cathepsin D. The enzyme selectively acts on the myofibrillar proteins of meat, resulting in a desirable uniform texture. The culturing of Trichoderma reesei in a medium containing glucose and lactose leads to a high yield of the enzyme.
