Food toxicity Flashcards
What are types of toxins?
additives
contaminants
pesticides
natural toxins
mycotoxins
What is de definition of additives?
Foodstuff additives with the exeption of colouring agents and
sweeteners
What are exampels of additives?
preservatives, flavor enhancers, antioxidants, packaging agents
What do you need to determine EDI?
- Concentration level compound in food
- Daily intake of foods containing the substance
- Distribution of food intake by population
- Potential substance exposure via non-food
How can you calculate EDI?
EDI = (CBfIf) + (CBgIf) + (C..etc.
CB = concentration of addtive B in cat f en g
I = daily intake of food cat f en g
What are mycotoxins?
poisons produced by fungi
What are examples of mycotoxins?
AFLATOXINE, penicillium, aspergillus,
What can you do to prevent mycotoxins?
Storage properly:
- right mix of water, nutrients, temperature and acidity
Preperation:
-heating sufficiently
-drying food storage
-low temp
-make more acidic.
What are contaminants?
dioxins,
PCB’s
Metals
microplastics
What are factors that influence migration of packaging in food?
-packaging properties
-water solubility
-fat solubility
-temperature
-time
What is an example of migration of packaging?
plastic fabrics migrate to fatty foods:
-oil, butter, meat
What are HCA’s?
Heterocyclic Amines
How do HCA’s form?
Preparing muscular meat at high temperature
What is functional food?
A food, which beneficially affects one or more target functions in the
body, beyond adequate nutritional effects
Wat is een voorbeeld van een risk benefit product?
Vitamine B12
benefit:
-prevention of cancer
risk:
- high intake = increase risk of cancer
moet dus in evenwicht zijn = homeostasis
