Benefits of technology

This patented method allows cows' skin or blood plasma (BP) samples to be treated beforehand without compromising their qualification. It does this by breaking down large amounts of these components with different techniques like sonolysis, heat treatment, acid/base treatments, etc., which helps them break up connections within each component material better than traditional methods such as boiling water extraction. By doing this, they become clearer images on electron microscopy, allowing researchers to study how tissue changes during disease processes occur over longer periods of time compared to older methods.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the stability and functionality of collagopepeptides during storage at high temperatures without losing their effectiveness when removed with activated charcoal powders that may leave behind unwanted odors.
