Testing of Food Ingredients

With the increased production of processed foods, manufacturers have started adding a large number of additives, generally in small quantities to improve the appearance, flavour, texture or shelf life of the processed foods. As certain impurities in these substances could be harmful, it is necessary to have a strict

quality control of these food additives. BIS has prepared a series of specifications including methods for checking purity and identification of these additives. It is desirable to know about the conformity of additives to specifications before intended use by manufacturers in specific processed foods. In this unit, the standard

and simple protocol for checking the purity and method of analysis of impurities in food additives are discussed.
