    Major Research Accomplishments

    One of the significant achievement was to established state of the art infrastructure facility as National Referral Center on Milk Quality and Safety (NRCMQS) which includes BSL-3 Containment under World bank funded NAIP project with fund support of 17.5 Crores in 2014 for addressing the scientific issues on milk safety in our country with the mandate to provide scientific solution in specialized field of milk safety and quality assurance; to carry out Risk Profile Work on Potential Contaminants in milk and milk products; development   of milk safety standards, sampling plan and testing procedures for regulatory compliance; Rapid Biosensor Based Tools/Assay/Kits for field application and to conduct training on HRD development on milk quality.

    BSL -3 Containment Established at NRC

    With the established facility at NRC rapid sensors were developed for detection of potential contaminants in dairy food chain by exploring bacterial spores as biosensor.Bacterial Spore as innovative approach for its application as bio-recognition element was successfully employed in rapid detection of antibiotic, pesticides and bacterial contaminants in dairy foods and their commercialization under field condition. Spore-based sensing technologies were developed to target many emerging contaminants in different types of food matrices, including milk and milk products in order to ensure food safety and quality. Different types of approaches were attempted for the development of spore-based biosensors for detection of antibiotic, pesticides and bacterial contaminants in milk.

    Paper Strip Based concept for Detection of Antibiotic Residues in Milk:

    Paper-based sensors are new alternative technology for fabricating simple, low-cost, portable and disposable analytical devices for many applications. The major advantages of using paper as a sensing platform include ease of availability, low cost, passive liquid transport, compatibility with chemicals/bio-chemicals  and fast response.  With these basic properties in mind, a spore-germination inhibition based assay for antibiotic detection was developed on the paper strip for exploring its potential under field application. The stages involved in developing paper sensors include the proper choice of paper, fabrication/patterning, and semi- quantitative analysis based on color development as a result of specific marker enzymes released during spore germination.The test involves pre-dipping of strip in milk and germination of spores in presence of germinant mixture when incubated at 64o C for 1:15 hrs. Development of blue color on paper strip indicates the absence of antibiotic residues and no color development indicates presence of antibiotic Residues in milk. The technology was developed under externally funded Outreach project on monitoring of drug residues and environmental pollutants funded by ICAR with fund support of 71 lakhs.

    Paper Strip Based concept for Detection of Antibiotic Residues in Milk

    Spore Based Kit for Detection of Antibiotic Residues in Milk at Dairy Farm: The developed technology is working on principle of spore germination and its inhibition in presence of antibiotic residues in milk. In case when antibiotic residues are absent in milk, marker metabolites are released during germination which change the color of the indicator. However, in presence of antibiotic residues in milk, the spore germination process is inhibited at ≥ MRL level of contaminants and no change in color indicates the presenceofdrugresiduesinmilkwhenincubatedat 64o C for 2.30 hrs.

    Technology was developed under externally funded Ministry of Food processing (MFPI) with fund support of 41 lakhs.

    Paper Strip based concept for Rapid Detection of Pesticide Residues: Pesticides are well known carcinogen and their impact on human beings and presence in different food products including milk are well known in the prior art. The existing conventional chromatographic methods (LC/GC-MS) are time- consuming and laborious. Currently, new standards for pesticides have been developed by FSSAI and implemented for regulatory compliance in different food products including milk. For routine monitoring of pesticides under field application, three stage assay on paper strip has been developed based on “spore germination and enzymeinhibition principle”. In case where analyte i.e. pesticide is absent, specific marker enzyme (s) are produced by spores during germination which will act specifically on chromogenic substrate resulting in colored end product on paper strip, whereas complete inhibition of marker enzyme will take place when pesticides are present in food sample (Patent Reg. 3819/DEL/2015).Simple and cost- effective technology for field application for testing of pesticides residues in milk, cereal based foods, fruit juices, feed, fodder, soil, water, manure etc. Technology was developed under externally funded Niche area of excellence (NAE) with funded  by Education Division ICAR with support of 121.420 lakhs

    Spore Based concept on Biochip for Listeria monocytogenes, Enterococci and E. coli in milk: A miniaturized spore based assay for detection of bacterial contaminants in milk on functionalized gold chip with minimal quantity of milk and other reagents with enhanced sensitivity was developed. The developed assay was integration with other consortia partners to have multi-analytehigh throughout put analysis for dairy applications. The spore enzyme assay was evaluated on biochip using EMCCD camera. The fluorescent signals were quantified in terms of integrated optical density (IOD).Patent on the technology has been published in IPO (1357/ DEL /2013) in Indian patent journal no. 50/2014, Dated12/12/2014. Technology was developed under externally funded NAIP project funded  by World bank with support of 22.0 crores
