What do you know about eggshell membrane (ESM)?

I come from a resource that everyone knows, EGG, more specifically, the MEMBRANE inside the egg.

Being part of the protection shell for an embryo, eggshell membrane (ESM) plays an important role in the birth of a new life. Awareness of it, ESM has been widely employed by Chinese people in medicine for thousands of years. From ancient of China, it is well-known as a remedy for coughing, wound recovery, and bone generation. Several great Traditional Chinese Medicine works have recorded its functions in “养阴,清肺, 治久咳,咽痛失音,瘰疬结核,溃疡不敛”. Apart from its medical function, nowadays, eggshell membranes are also popular as a home-made natural skin care recipe for a clean and silky skin. Such magic functions are not groundless. Modern scientific researches which included our own R&D department have proved ESM’s effectiveness in cell proliferation and free radical elimination, which results from its protein-rich composition and unique skin-mimic structure.

It is primarily composed of fibrous proteins such as type I and V collagen. Additionally, eggshell membrane also contains glycosaminoglycans (e.g. dermatan sulfate, chondroitin sulfate and hyaluronic acid), glucosamine, sialic acid, desmosine and isodesmosine (responsible for the rubber properties of elastin). Our R&D team has demonstrated that eggshell membrane hydrolysates have anti-inflammatory, anti-microbial activity and can inhibit collagenase and elastase activities revealing an anti-wrinkle property.

Besides its excellent biofunctions, ESM is also an easy-accessible resource with abundant quantity. Taking Netherlands only into account, 30 million eggs are processed every day, resulting in 18 tons of ESM proteins. This number can be further enlarged to 2,000 tons per day in worldwide. It is undoubtable that enormous amount of value can be created from this renewable resource if it can be properly developed. Unfortunately, in reality it is not the case. The values are seldom known by the egg processing industry, sadly speaking worldwide. Most of them are disposed as a waste stream and ended in landfill without any value.
