   纳他霉素--近白色或奶油黄色结晶粉末。是一种无臭、无味，低剂量且安全性高的食品防腐剂。纳他霉素(Natamycin)，是由纳他链霉菌受控发酵制得一种白色至乳白色的无臭无味的结晶粉末，通常以烯醇式结构存在。它的作用机理是与真菌的麦角甾醇以及其他甾醇基团结合，阻遏麦角甾醇生物合成，从而使细胞膜畸变，最终导致渗漏，引起细胞死亡。在焙烤食品用纳他霉素对面团进行表面处理，有明显的延长保质期作用。

Introduction

Natamycin (also known as Natamicina, Natamycine, Natamax, Natacid) is a new broad and high-effective natural food preservative and the only approved anti-fungal preservative in the international area. Natamycin not only inhibits the growth of fungi, but also inhibits the production of their toxin. Natamycin has no effect on bacteria, so it does not prevent the natural maturing process of yogurt, cheese, fresh harm, sausage, etc. It would not impact food taste. Meanwhile, natamycin is difficult to be absorbed by human digestive tract so that it is safe for human being. Until now Natamycin has been approved as food preservative in more than 40 countries, and is widely applied in cheese, meat food, cakes, fruit juice/sauce/jelly, salted products, and other foods.
