The Seminar
Inspired by Martin Luther King Jr. “I have a dream” speech
He talks about dreams and how to achieve them
Careers not necessarily linear
Unexpected can occur and does occur
His own career has been diverse, interesting, rewarding, sometimes frustrating and enjoyable
Food Forecast
Organically grown foods
Bio-engineered foods
Convenience will hold prominence
Example- microwavable foods
1991 – Your computer will determine your nutritional requirements. Now happening
Fergus Clydesdale (University of Massachusetts)
in 2004 – Envisioned appearance of functional foods in stores; now we see them
Current State
Poor don’t know from where their food is going to come tomorrow
See newspapers for policies
Whom do they benefit?
Projection:-
World Population to increase by 40% by 2050 from 6.5 billion to 9.1 billion
By 2050, world food requirement will double
1.3 Billion people live on $1 a day
2 Billion more people live on $2 a day
Food technologists and scientists will play a key role in meeting the demand
It is our onus to ensure food security for the underprivileged
Target 2015: The World Food Summit
… a reaffirmation of the right of everyone to have adequate, safe and nutritious food
What is The World Food Summit (WFS)?
- 1996: 180 nations met at FAO HQs (now in Rome)
- Discussed ways to end hunger
- Commitment – reducing number of undernourished people by half by 2015
This should be our goal too as a food scientist
Mission of a Food Science and Technologist: To create new knowledge and to develop processes
Food Safety
It means more than consuming food that doesn’t harm us
Includes accidents, environmental effects & terrorism
Integration of toxicology, nutrition, microbiology, genetics, environmental sciences
Food Supply and Safety Chain
Farm - Transportation - Food Processor – Transportation - RetailCurrent Mega Trends
One Stop Nutrition
Guilt free indulgence
Convenience Plus
Health, Convenience, Pleasure
Well being, time, sensory
All combined is
Food Safety
Time to prepare food needs to be decreased, while maintaining same food safety levels
Need For New Technologies
Required for maintaining and improving food safety
Newer Technologies:-
-- Modern Biotechnology
-- Nano-engineering
-- …omics ~ Genomics, Transcriptomics, Proteomics,
Metabolomics, Nutrigenomics
In US, not too much stress on ‘authenticity’
Example – Honey may not be 100% honey, but still sold as honey. Potential for Metabolmics
Food Scientists’ Task
Food Scientists – Need to be involved in generating new knowledge for advances related to food technology; address food safety issues
Consumers have concerns regarding new technologies:-
-- Citizens request USFDA to stop the use of nano-tech
in food packaging until laws were formulated
-- Apprehension regarding food irradiation
Role of food scientists to educate the consumer
Too much variation between individuals; one recommendation doesn’t apply to all
Increase in incidences of microbial food-borne disease outbreaks
Food microbiologists will play important role
Give attention to identification and characterization of microbes
There is a bigger challenge still-
To identify incidences before their occurrence.
Lookout for symptoms
Example – the cause for outbreak may lie outside the manufacturing facility (the transportation)
Interesting
Increased sensitivities of analytical methods
Now able to detect analytes at extremely low concentrations
Some substances can have potential adverse human effects
Example: acryl-amide
Again Food Scientists have to reassure consumers about Food Safety
Other Food Safety Concerns
Increasing incidence of food allergies
Food Irradiation and acceptance
Attracting more students into the field
REITERATION!!!
Collaborative efforts required
Food Scientists will have to play a big role
Conclusions
21st Century – time of rapid change
Many challenges (for Food Industry)
Many Opportunities (for Food Scientists)
Much responsibility (of Food Scientists)
The Excitement of a challenging future
The demanding task of providing citizens of the world with safe and nutritious food
