Each year, about 10%–20% of agricultural and sideline products, aquatic products, fruits and vegetables rot around the world, causing huge economic losses and endangering human health. To resolve this problem, food preservatives are added to food to fight spoilage caused by bacteria, molds, fungus, and yeast. Preservatives can keep food fresher for longer periods of time, extending its shelf life. The commonly used food preservatives are also used to slow or prevent changes in colour, flavour or texture and delay rancidity. In addition, preservatives can be applied in medicine, pharmaceuticals, cosmetics and personal care products.
