Low calorie food and drink > sweeteners, stevia, fat replacer
Low salt food > sodium replacer, spices
Functional Food > fortified food
Personalized food > aging and aged society
Natural conscious coloring > children food, candy, fruit juice
Natural flavoring > wide product range for food products
Delicious is still key

Food Security : challenge of feeding 9.6 billion by 2050
3 main challenges :
✓ Meet demand for food from rapidly increasing and more
affluent global population
✓ Do so in environmentally and socially sustainable ways
✓ Ensure that world’s poorest people do not go hungry

World Food Trends- 1
Competition is severe and slow down in economic growth. There is a need to:
• Streamlining or modernizing operation by automation to offer quick and easy processing
• tackling food loss and food waste by making use of all parts of any raw material to achieve zero waste and introduce the 3Rs concept: reduce, reuse, recycle
• Strictly in compliance with food safety management system
• Up-to-date with consumer tastes and health trends
• Understand both industry and market trends

World Food Trends- 2
Competition is severe and slow down in economic growth.
There is a need to:
• Flexible in processing lines to cater new product
development with the science based system
• Fundamentally global: new wave of international cuisines
through consumer curiosity and exposure to international food and flavor e.g., fermented vegetable, traditional charcoal grill, more ingredients of medicinal herbs
• Experience dichotomy: exploration for new and complimentary experiences: calorie intake from meals, indigenous dishes

Food Safety and Quality
o Food safety is a global issue
o Consumption of wholesome foods, good quality and safety and right nutrition is one of the basic human rights
o There are widespread food safety risks and unsafe food incidents in different parts of the world
![Page 15: Food lnnovation and Food Science Multidisciplinarity · –Service minded and fast service –Value for money –Reflect the wisdom and culture of Thai nation. ... • Up-to-date](https://reader033.vdocuments.mx/reader033/viewer/2022042622/5f7d2b553e0ce94dee4d5c6e/html5/thumbnails/15.jpg)
Food can become unsafe due to several reasons
Why food not safe!-1
Emerging foodborne illnesses problems
Change in pathogens through adaptation by natural selection
Dietary habits of preference and practices and cultural beliefs may be the causes
Food trade of plant and animal origin is increasing rapidly and contributed to the spread of foodborne problems to new areas
![Page 16: Food lnnovation and Food Science Multidisciplinarity · –Service minded and fast service –Value for money –Reflect the wisdom and culture of Thai nation. ... • Up-to-date](https://reader033.vdocuments.mx/reader033/viewer/2022042622/5f7d2b553e0ce94dee4d5c6e/html5/thumbnails/16.jpg)
Food can become unsafe due to several reasons
Why food not safe!-2
Economic and technical development of new food, new production system or new environmental changes increase opportunities for contamination due to lack of knowledge from food handlers and an increase in mass catering
Poverty and pollution, environmental contamination
Poor social conditions and lack of safe food preparation facilities
![Page 17: Food lnnovation and Food Science Multidisciplinarity · –Service minded and fast service –Value for money –Reflect the wisdom and culture of Thai nation. ... • Up-to-date](https://reader033.vdocuments.mx/reader033/viewer/2022042622/5f7d2b553e0ce94dee4d5c6e/html5/thumbnails/17.jpg)
Food can become unsafe due to several reasons
Why food not safe!-3
Travel and migration of millions of people crossing borders can spread disease rapidly to new environment
Poor hygiene practice of food handlers of street food and the improper storage of raw ingredients esp. meat and seafood items
Inappropriate time and temperature in processing
Improper cleaning and sanitizing
Contamination and cross contamination

Why food safety is a must for any food enterprise?
Consequence of producing unintentionally or intentionally
unsafe food:
• consumer gets sick
• Government authority intervene in this incident
• Ruin business and may end up with bankruptcy
• Ruin national reputation if it is a serious incident
![Page 19: Food lnnovation and Food Science Multidisciplinarity · –Service minded and fast service –Value for money –Reflect the wisdom and culture of Thai nation. ... • Up-to-date](https://reader033.vdocuments.mx/reader033/viewer/2022042622/5f7d2b553e0ce94dee4d5c6e/html5/thumbnails/19.jpg)
Food safety and quality management system
➢ Food safety is an extreme important tool for any food enterprise!
➢ Food quality and safety management system is a preventive tool, it is to reduce chance of producing poor or lower than standard food!
➢ Well trained staff is key to achieve the goal of producing safe food!

Food processing and preservation-10
Food additives: safety issues
➢ More than 3,000 compounds recommended by FDA as food
additives and have GRAS (Generally Recognized As Safe) status
➢ Each country has its own set of rules
➢ Still concern as to their harmfulness
➢ New additive must go through rigorous risk assessment:
hazard identification and characterization, exposure assessment,
risk characterization, and risk management to control hazardous
conditions

Conclusion : “Food Safety ”
• safe food with excellent quality for health is a must!
• must not be compromised in funding, research and knowledge dissemination
• networking and partnership must involve policy makers, agri-food producers/farmers, food manufacturers, distributors, retailers and the general public
A sound food safety management system is one that identifies, evaluates and controls hazards in food safety, by taking a systematic and preventive approach by anticipation and prevention not by end-product inspection and testing

Take home messages!
• What would happen to the existing world population if there were no agro-food business?
• We do have food processing manufacturers!
What if we did not have well professional food scientists/technologists?
Who would look after food safety and new food products?
What would be the health of our populations?
