what is clean label platform?
reduce number of ingredients in foods, promote natural ingredients, focus on front on package info
benefits of food additives?
safer food supply, more nutritious food supply, wider choice of food products, lower prices
why safer food supply?
antimicrobials, antioxidants, sulfites
what do antimicrobials do?
prevent/delay food poisoning
what do antioxidants do?
delay development off flavours/odours; inhibit formation toxic comps
what do sulfites do?
inhibit non-enzymatic browning and formation of potential carcinogenic comps
why more nutritious food supply?
slow/stop destruction nutritionally important food comps, replace of xs cals, ^ shelf life and food quality, ^ nutr by adding nutrients
examples wider choice food products?
convenience, diet restriction, out of season available all year
country with >40% income spent on food?
Pakistan
what are risks of food additives?
direct toxicological effects: almost all insufficient sci data prove absolute safety, health effects of combos, food additive-food component complexes
what is food additive toxicology?
study of adverse effects of chem present in foods on living orgs
intensity of bio response depends on _____ of comp
dose and purity
what are dose response experiments?
pop. of orgs subjected to range of doses of chem compound over defined time period–>produce response vs. dose graph, plot NOAEL values
what is NOAEL?
highest exposure lvl of comp resulting in no detectable toxic effect in animals
how determine NOAEL?
subchronic/life-span studies
