2. 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

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

4. What are Biosensors?

6. Classification of Biosensors
• Enzymes
• Proteins
• Antibodies
• DNA
• Organelles
• Microbial
Cells
Biological Recognition Transducer and
Measured Property
•Electrochemical
• Electrical
•Optical
• Mass Sensitive
•Thermal

7. 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.

8. Uses of Biosensors

9. Usage of Biosensors in Food Industry
• PH
• DNA Testing
• Alcohol Testing
• Sugar Content Testing
•Contamination in packed Food

11. A Typical Biosensor

12. 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

13. Biosensors in Agriculture
• Testing for pesticides in the
crop.
• Soil ph testing
• Crop deterioration test
• Crop respiration detectors
• Gases detectors
• Environmental pollutants

14. Trending Biosensors
E- nose
• Sensory Analysis Software (accuracy)
• Detection of odd volatile compounds
• Application in Tea, Wine, Coffee, Spices
Industry

15. Trending Biosensors
E- Tongue
• Used when a combination of
volatiles and their effect on sensory is
to be analyzed.
• Applications in Tea, Coffee,
Beverage (liquid food industry).

16. Indian scenario in usage of Biosensors
Research 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.

17. Global scenario in usage of biosensors
Pathogen Detector Toxin detector using
Smartphone app
E-Tongue (Handy) Calorie Counter

18. 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

19. Nano-sensors for Food Safety

20. Companies manufacturing Food Biosensors

21. 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.

22. 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.
