Soy Flashcards
what can soy protein be used as?
an imitation meat product
what is the soy protein composition
90% of proteins are for storage
Beta- conglycinin
- glycoprotein with 3 subunits (alpha, beta, alpha-prime)
- forms transparent, soft, elastic gels
Glycinin
- a hexamer with numbered subunits (1a, 1b, 2, 3, 4, 5) that are linked via disulfide bonds
- form hard gels
what is soy protein isolate
the most refined type of protein made by solubilising defatted soy flakes and precipitating them with acid at the isoelectric point, and then separating the proteins from the flake and spray drying
what are the functional properties of soy protein
high water holding capacity
- good binding properties
gelation
- uses in meat, soup, baking
emulsification
- fat binding
texturisation
- meat extenders and replacers
what are the uses of soy flour
browning
freshness
tendering
what are the uses of soy concentrate
