part 8 Flashcards
fats nutrition properties:
EFAs, biocule precursor, energy
fats functional properties:
carriers of lipid sol vits and flavour comps; heat transfer in foods; processing method (frying)
fats organoleptic properties:
flavour, mouthfeel, ^ palatability
fats are additives. True or False?
false: ingredients
can vary hydrophilic-lipophilic balance of cule through lipid used to form ester linkages, heat stable, provide same taste/texture/mouthfeel of lipids
sucrose esters
___ means not absorbed cuz steric effect
4; 4
probs of sucrose esters (like olestra):
impaired fat sol vit and carotenoid absorption; intestinal dysfunction (loose stool, diarrhea, anal leakage)
does olestra have GRAS status?
nope –but allowed as fat replacer in some places with warning label
olestra is approved as ___ in Canada
emulsifier
benefits of sucrose esters?
reduced cal/wt loss, reduce LDL, more rapid removal of toxicants like PCBs
owned by Monsanto (NutraSweet Co.) and produced from milk/egg protein by vigorous blending/shearing (microparticulation) and controlled heating to produce spheroidal small particles <3mcm that tongue perceives as creamy fluid
simplesse
why simplesse not stable under high temp processing?
cuz it is a protein (so use in min. processed foods)
probs of simplesse
allergenic reaction, very few toxicity studies, limited food use
developed by Nabisco for cocoa butter replacement, poorly absorbed, full name of “short and long acyl triglyceride molecule”
salatrim (benefat)
why poorly absorbed salatrim?
stearic acid
