Chitosan: What Are The Origins of Chitosan
Chitosan has long been considered as the magic substance that binds fat and stop it from accumulating in our bodies. Chitosan is effectively a magical fat inhibitor which work wonders for those in search of a safe way to lose that body fat.
What is chitosan made from? It is taken from chitin, a polysaccharide found in the exoskeletons of crustaceans. It is manufactured by removing the shells from the shellfish like lobster, shrimps and crabs.
So, how and when chitosan was discovered?
The origin of chitosan can be traced back to 1811 when “chitin”, from which it is derived, was first discovered by Braconnot, a then professor of the natural history in France. According to some researches, while Braconnot was conducting research on mushrooms, he isolated what was later to be called chitin.
Twenty years later, there was a man who wrote an article on insects in which he noted that similar substance was present in the structure of insects as well as the structure of plants. He then called this astounding substance as “chitin”.
Basically, the name chitin is derived from Greek, meaning “tunic” or “envelope”. The concept was further known in 1843 when Lassaigne demonstrated the presence of nitrogen in chitin.
Following the discovery of chitin, the name “chitosan” emerged in the scene. It was first discovered by Rouget while experimenting with chitin. Rouget observed that the compound of chitin could be manipulated through chemical and temperature treatments for it to become soluble. Then, it was in 1878 when Ledderhose identified chitin to be made of glucosamine and acetic acid. It was not actually until 1894 that Hoppe-Seyler named the tailored chitin, chitosan.
During the early 20th century, several researches took chitosan as their subject of study. They then involved sources of chitin, including crab shells and fungai. It was the work of Rammelberg in the 1930s that led to the confirmation on the identity of chitosan from these sources. It was also noted that by hydrolyzing chitin in several ways, it was determined by experts that chitin is a polysaccharide of glucosamine.
During the 1950s, the use of x-ray analysis had advanced the study of the incidence of chitin or chitosan in fungai. However, it is only the most advanced technologies that proved the most reliable in accepting the existence of chitin as well as cellulose in the cell walls. The first book on chitosan was published 140 years after the initial observation of Braconnot, and that was in 1951.
During the early 1960s, chitosan was examined for its ability to bind with the red blood cells. That time also, the substance was considered as a hemostatic agent. Then, for the past three decades, chitosan has been used at water purification plants for detoxifying water. It is spread over the surface where it absorbs greases, oils, and other potential toxins.
Nowadays, Chitosan it is known as a dietary supplement that is good for weight loss. In fact, it has been marketed for such purpose for about 20 years in Japan as well as in Europe.
So, although Chitosan is taken as the ‘wonder’ pill of today, it has been around for ages and has been a subject since the 1811.
