What does food science study?
Food science studies, the nature of food, how it deteriorates, and the scientific principles behind processing preservation and safety
How do every day choices influence, the food industry?
Individual choices like oat milk vs dairy, fresh vs frozen, send sign signals when when consumers make the same choice, it becomes consumer demand that drives product development
Why does consumer demand matter to the food manufacturers?
Manufacturers develop reformulate or discontinue products to meet changing consumer preferences, and remain profitable
Give examples of how consumer demand shapes food products
Less sugar = reformulated products
Longer shelf life = new preservation methods
Convenience = ready to eat meals
Why does food science exist partly because of consumers?
Food science helps the industry respond, scientifically, and efficiently to consumer expectations for safety quality, convenience, and shelf life
What major sciences intersect in food science?
Food biology, chemistry, and physical sciences
What role does food biology focus on?
Microorganisms, enzymes, spoilage, and fermentation
What role does chemistry focus on in food science
It explains reactions nutrients additives and flavour compounds
How do physical sciences contribute to food science?
Through principles like heat, pressure, freezing, and drying used in food processing
Why is food science considered interdisciplinary?
Because understanding food requires biological chemical and physical principles working together
Why is the idea of chemical free food incorrect?
All food is made up of chemical components; without food chemicals would not exist
(carbohydrates, proteins, fats, water, and micro nutrients)
How does food science challenge food marketing myths?
It shows that chemical free claims ignore basic chemistry about food and are misleading
What is the main job of food scientists?
To keep food, safe, edible, and available for longer using engineering and scientific principles
Why is food preservation essential?
Without preservation food would spoil extremely quickly due to microbes and chemical reactions
Are all processed foods unhealthy? Explain
No processing exists on a spectrum and many processed foods are necessary for safety and shelf life
What characterizes minimally processed foods
Foods altered slightly for a convenience or safety without changing their structure (shelled almonds, bagged spinach)
What defines basic processing?
Simple methods that extend shelf life by removing moisture or reducing microbial growth (dried fruit)
What is moderately processed food?
Foods altered through fermentation or baking for safety, taste and shelf life (cheese, bread)
What makes a food highly processed
Foods processed beyond safety needs with multiple added ingredients (frozen pizza, soda)
What processing methods use physical or engineering principles and how do they improve food safety?
Healing drying packaging, pressure, cooling, and freezing
They kill or slow microorganisms and slow chemical reactions
What are the outcomes of applying these methods?
Reduced spoilage increased shelflife, and safer food
What is the food industry and how is modern food production structured?
Food industry is a large profit driven system that produces, processes, distributes, and markets food. It’s industrialized, global and highly coordinated.
Where does food science fit in the agricultural food system?
It transforms raw agriculture, commodities into consumer food products
(Wheat to bread)
Describe the basic flow of the agriculture food system
Farm to Food Processing to Food on a consumers plate
