Good at present is completely harmless to the human body, and those who are controversial must still have certain problems. Food additives for sale-Natamycin is a common food additive that mainly plays an antiseptic role. So, what are the side effects of natamycin?
Food additives for sale. Natamycin relies on its lactone ring structure to interact with sterol compounds on the fungal cell membrane to form antibiotic-sterol compounds, thus destroying the structure of the fungal plasma membrane. The hydrophilic part of the macrolide (polyol part) forms water holes on the membrane, which damages the permeability of the cell membrane, and then causes the leakage of amino acids, electrolytes, and other substances in the bacteria, and the death of the bacteria. When there is no sterol compound on the cell membrane of some microorganisms, natamycin has no effect on them, so natamycin only inhibits fungi and has no antibacterial activity on bacteria and viruses.
Natamycin is a natural, broad-spectrum, efficient, and safe inhibitor of filamentous fungi such as yeast and mold. It can not only inhibit fungi, but also prevent the production of mycotoxins. Food additives for sale. Natamycin is harmless to the human body, which is difficult to absorb by the human digestive tract, and it is difficult for microorganisms to produce resistance to it. At the same time, because of its low solubility, it is usually used for surface preservation of food.
(1)Possible allergic reaction
Although rare, individual consumers may be allergic to food additives for sale natamycin, showing itchy skin, rash, or gastrointestinal discomfort.
In food processing, natamycin is usually only used for surface treatment (such as cheese shells and sausage casings), and its intake is extremely low, so the risk of allergy is small.
(2) Potential effects of long-term intake
Drug resistance: Long-term low-dose exposure to food additives for sale as natamycin may lead to drug resistance of some fungi (such as yeast), which may affect their antibacterial effect.
Influence of intestinal flora: Although natamycin mainly inhibits fungi, long-term excessive intake may affect the balance of intestinal microorganisms, especially on probiotics (such as some yeasts).
(3) Risk of overuse
China's National Food Safety Standard (GB 2760-2014) stipulates that the maximum dosage of food additives for the sale of natamycin in food is generally 0.3g/kg (surface residue ≤10mg/kg).
If enterprises use it in excess in violation of regulations (for example, some cakes are found to be 17.4mg/kg, nearly twice the standard), it may increase the exposure risk of consumers. Although its oral absorption rate is low, it may still have an impact on sensitive people (such as children and pregnant women).
Therefore, food additives for sale natamycin, have no side effects. Of course, because it can be applied to a variety of foods, we should pay attention to the difference in dosage. Although the use of some food additives in China is not very standardized, it is believed that with the establishment of relevant systems, several controversial additives will be gradually eliminated, and other standards will gradually be in line with international standards.
