Chitosan: a marine fibre used in functional nutrition
Chitosan is a dietary fibre of marine origin obtained from chitin, a natural substance found in the exoskeleton of crustaceans. In the field of functional nutrition, this fibre attracts attention for its particular molecular structure and for the way it interacts with certain nutrients present in food.
Unlike conventional plant fibres such as psyllium or inulin, chitosan has a cationic chemical structure capable of interacting with certain lipid compounds in the digestive system. That characteristic explains why it is the subject of a great deal of scientific research in nutrition and metabolism.
What is chitosan?
Chitosan is a natural polysaccharide derived from chitin. Chitin is a major structural element of the shells of crustaceans such as prawns, crabs and langoustines.
During manufacture, chitin undergoes a transformation called deacetylation. This step produces chitosan, a fibre studied for its physicochemical properties and its interactions within the digestive tract.
- Dietary fibre of marine origin
- Natural polysaccharide
- A structure rich in amine groups
- Possible interaction with certain dietary lipids
Chitosan and dietary fibre
Dietary fibre plays an essential role in nutritional balance. It contributes to the normal functioning of the digestive system and takes part in the overall fibre intake of the diet.
Chitosan belongs to the category of functional fibres. That term refers to fibres studied for their specific interactions with certain nutrients.
Dietary fibre can in particular:
- increase the volume of the food bolus
- take part in the regulation of intestinal transit
- contribute to the feeling of fullness
- play a role in the balance of the gut microbiome
According to the European Food Safety Authority (EFSA), a sufficient intake of dietary fibre contributes to good digestive and metabolic function.
How chitosan interacts with dietary lipids
One frequently studied characteristic of chitosan concerns its ability to interact with certain lipids present in food. Its positively charged molecular structure can encourage the adsorption of certain lipid molecules in the food bolus.
These physicochemical properties have been the subject of a great deal of scientific work in nutrition and metabolism.
A scientific review published in Obesity Reviews indicates that chitosan has a capacity to adsorb lipids under certain digestive conditions.
Chitosan in the functional nutrition approach
Functional nutrition is concerned with ingredients capable of interacting with the various physiological mechanisms linked to food.
In this approach, dietary fibre occupies a central place because it can influence several physiological parameters:
- digestion
- satiety
- intestinal balance
- interaction with certain nutrients
Chitosan is one of the fibres studied in this context, because of its particular structure and its potential interactions with dietary lipids.
How to take chitosan
Chitosan is generally offered as a food supplement. Usage recommendations may vary depending on the formulation.
In many cases it is advised to take chitosan with meals in order to …
