GRAIN QUALITY TESTING LAB

 

INTRODUCTION
Grain Quality Testing Lab is an important component of Food Quality & Nutrition Programme. It was recently established under the special instructions of The President of Pakistan. The main purpose of the lab is to provide all the facilities for grain quality testing under one roof. In coming future, Grain Quality Testing Lab will play a key role in determining the quality of the grains in order to meet the challenges of export and import of the commodities. The main objectives of Grain Quality Testing Lab are as follows:

 

OBJECTIVES

ACTIVITIES
Analysis and certification of Agricultural Products

 

ACHIEVEMENTS
Establishment of Grain Quality Testing Laboratories (GQTL)

  1. A state of the art laboratory was established in June 2004. It was equipped with most sophisticated 68 types of equipment for undertaking tests. All the equipments were installed and scientists were trained to their use.

  2. Six scientists were trained through an extensive training program of eight weeks at Canadian International Grains Institute, the world renowned institute for research and training on grain testing.

  3. The laboratories have developed procedures for undertaking 29 types of grain tests in following areas and are fully functional:

        a. Physical quality characteristics of grains
        b. Cereal chemistry and cooking quality
        c. Pest and Disease related to grain
        d. Environmental safety aspects viz pesticide residues, heavy metals and mycotoxins.
        e. Microbiological and pathological testing

 

Support to Import/Export

  1. All the wheat imported by Pakistan from 2004 and 2006 through TCP and private sector from Russia, USA and Australia was analyzed in these laboratories for quality assurance.

  2. The wheat imported by private sector from Australia in 2004 was testing and rejected by these laboratories.

  3. About 0.86 million tons of wheat imported by private sector in 2004-05 from Russia, USA and Australia was inspected and analyzed at load / discharge port by the staff of these laboratories.

  4. The laboratories are providing technical support to Punjab Food Department for meeting the technical specification of Indian Govt. Tender for import of 3.00 million tons wheat.

  5. The laboratories interact with MINFAL on technical matters related to wheat quality specifications for imports / export.

  6. Laboratories are also providing testing/certification facilities to fruits and vegetables exporters on pesticide residues and heavy metals to facilitate their exports.

Research and Development Programs:

  1. The laboratories undertake survey of wheat growing regions of Punjab and NWFP every year. So far about 2500 samples of wheat have been collected and analyzed for incidence of diseases and about 500 for complete quality analysis.

  2. As a part of in-house research program the laboratories have analyzed 129 samples of fruits and vegetables for pesticide residues and 114 for heavy metals to facilitate exports.

  3. The laboratories have provided analytical services to private food / fruits / vegetables dealer for analysis of about 1500 samples annually.

  4. The laboratories are providing the support to educational institutions by housing their Ph.D, M.Sc. and internship students on topics of mutual interest. So for 29 students have / are beneficiated and many of them are serving the food industry.

 

Accreditation of Laboratories:

 

Laboratory has been selected under EU Trade Related Technical Assistance (TRTA) project for technical support leading to ISO 17025 accreditation. Application for ISO 17025 accreditation was submitted to Norwegian Accreditation Body and laboratory has successfully passed the first assessment which was done in February 2007. Now Grain Quality Testing Laboratories are accredited by Norwegian Accreditation.
