Food Quality Checks• Involves making sure the agricultural produce is microbe/pathogen free.• Making sure that raw material is being handled safely.• The processing operation is pathogen free.• Food testing in laboratories.• GHP and GMP

Problems with Food Analysis•Sample preparation is
tedious job.
•Results may not be reproducible.
•Results may be inaccurate.

![Page 6: Biosensors in food industry’ presentation by Sonika Singh, NIFTEM, M.tech First year](https://reader033.fdocuments.in/reader033/viewer/2022052117/587e09db1a28abe11a8b688f/html5/thumbnails/6.jpg)
Classification of Biosensors
•Enzymes•Proteins•Antibodies•DNA•Organelles•Microbial
Cells
Biological Recognition Transducer and Measured Property
•Electrochemical• Electrical•Optical• Mass Sensitive •Thermal
![Page 7: Biosensors in food industry’ presentation by Sonika Singh, NIFTEM, M.tech First year](https://reader033.fdocuments.in/reader033/viewer/2022052117/587e09db1a28abe11a8b688f/html5/thumbnails/7.jpg)
Conventional modes of food analysis and their disadvantages-
•Expensive•Time
Consuming•Changes the
morphology of the food
CASE STUDY- How sampling destroys the real analysis of a food product.

Biosensors in Dairy Technology•DNA testing of the cows•Pathogen Testing in the milk•Milk bacterial Load• Micro-organism Identification in the milk• Test for preservation and pasteurization
![Page 13: Biosensors in food industry’ presentation by Sonika Singh, NIFTEM, M.tech First year](https://reader033.fdocuments.in/reader033/viewer/2022052117/587e09db1a28abe11a8b688f/html5/thumbnails/13.jpg)
Biosensors in Agriculture• Testing for pesticides in the
crop.• Soil ph testing• Crop deterioration test• Crop respiration detectors• Gases detectors• Environmental pollutants

Indian scenario in usage of BiosensorsResearch and Development is less; companies depends more on usage of conventional systems
Usage of Biosensors are limited to medical field.
Not manufactured in India. Custom made are expensive.

Nano-sensors in Food Packaging Nanotechnology offers 3 distinct advantages to food packaging-•Barrier resistance• Incorporation of active components to provide functional performance• Sensing of relevant information
Application in this area already support development of improved-
• Taste, colour, flavour, texture and consistency of foodstuffs, increased absorption and bioavailability of nutrients and health supplements.• New food packaging materials with improved mechanical, barrier and antimicrobial properties

Companies manufacturing Food Biosensors
![Page 21: Biosensors in food industry’ presentation by Sonika Singh, NIFTEM, M.tech First year](https://reader033.fdocuments.in/reader033/viewer/2022052117/587e09db1a28abe11a8b688f/html5/thumbnails/21.jpg)
Conclusion• The potential is infinite.
• Developmental stage; unorganized.
• India lags in food quality.
• Companies reluctant want to invest in R & D and food quality.
• With stringent food regulations, the quality assurance might increase and hence would increasing the usage of biosensors.
• Handy food biosensors will eliminate the need of conventional biosensors.
![Page 22: Biosensors in food industry’ presentation by Sonika Singh, NIFTEM, M.tech First year](https://reader033.fdocuments.in/reader033/viewer/2022052117/587e09db1a28abe11a8b688f/html5/thumbnails/22.jpg)
The last fraction… • A handy biosensor that beats all the
biosensors/food testing equipments ever.
• How can Indian industries use biosensors for quality assurance.
• From Field to table- Biosensor usage in fresh foods.
• Small, medium and large scale industry- how could biosensors make a difference in terms of quality.
