natural preservatives safety

Artificial food preservatives have revolutionized the food industry to ensure longer food shelf life. This has promoted the wide distribution and mass production of food and opened up new markets. In addition to extending the shelf life, preservatives also have other functions in food production. For example, processed and refined foods require the use of preservatives to inhibit natural aging and discoloration. In addition, certain preservatives can also be used for rheological purposes. They act as emulsifiers, stabilizers and thickeners to give foods the desired texture and consistency.
