The use of natamycin generally does not have a significant impact on the nutritional value of food, and the reasons are as follows:
Stable in properties: Natamycin is a polyene macrolide antifungal agent with good stability. Under normal food processing and storage conditions, it will not undergo chemical reactions with the nutrients in food, and will not cause structural changes or losses of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals.
Extremely low dosage: Natamycin has strong antibacterial activity, and its usage amount in food is usually very low, generally ranging from dozens to hundreds of milligrams per kilogram. Such a trace amount of addition has almost no impact on the overall content of nutrients in food.
Not absorbed by the human body: Natamycin is poorly soluble in water and most organic solvents, and is hardly absorbed by the human body. Instead, it is excreted in its original form through feces. This means that it will not participate in the metabolic processes of the human body, nor will it interfere with the human body's intake of nutrients from food.
However, if natamycin is used in excess in food, it may have a certain impact on the sensory qualities of food, such as flavor and texture, and indirectly affect people's acceptance and intake of food. From this perspective, it may, to a certain extent, affect the realization of the nutritional value of food. But as long as it is used in accordance with relevant standards and specifications, the impact of natamycin on the nutritional value of food can be negligible.
