FSSAI publishes order regarding manuals of methods of analysis of various food products

Ever since the FSSAI was formed the DGHS manuals of test method for analysis of the various products, which were prepared 20 years back were being used. The FSSAI has now planned incorporated new methods of analysis in the newFSSAI manuals of methods of analysis for various food product categories. The FSSAI has taken this step as there have been a number of developments and advancements in the analytical field. The FSSAI has reviewed the old DGHS methods in the light of these developments and the manuals have been reviewed and approved by the Food Authority after a series of meetings of the Scientific Panel, Scientific Committee and Food Authority and public consultation.

The Food Authority has termed these manuals mentioned below as the ‘FSSAI manuals of methods of analysis’ and shall be used by the laboratories with immediate effect. The process of updating of test methods is dynamic due to new developments taking place from time to time in the field of food testing therefore if there are any queries they may be forwarded to email: labs@fssai.gov.in

The FSSAI further says that the test methods given in the manuals are validated/ standardized test methods. However, it would be the responsibility of the respective testing laboratory to confirm that the above methods are validated in its laboratory and gives proper result in their laboratory. The FSSAI has outlined the methods of taking samples, preparing the sample for testing, the reagents to be used, various testing methods, procedures, apparatus and where required the methods of calculation are given for various tests in the manuals.

This is not a comprehensive list of all the tests but just a few common tests that are carried out in the 9 categories termed as. Each of these nine categories has a separate manual that provide guidelines for testing various methods.

  1. FSSAI manual on methods of analysis General Guidelines on Sampling

In this analysis manual FSSAI has prescribed methods of sampling that have been designed to ensure that fair and valid sampling procedures are used when food is being tested for compliance with a particular commodity standard. The sampling methods are intended for use as methods designed to avoid or remove difficulties which may be created by diverging legal, administrative and technical approaches to sampling and by diverging interpretation of results of analysis in relation to lots or consignments of foods. It is an attempt to ensure that there are uniform sampling methods.
