Non-enzymatic browning Flashcards
what is non-enzymatic browning
chemical reaction that requires a lot of energy
what is non-enzymatic browning classified as
dehydration reaction
what does thermal degradation mean
it cannot turn into a gas
what does the Maillard reaction do to a reducing sugar and an amino acid
links them together
what do acids generate
H+ ions
what makes something an alkali?
takes away H+
what is an alkaline bath
water and baking powder, typically for bagels and pretzels
how is an amadori compound formed
amino acid+reducing sugar+heat
large (chemical structure) amadori compound
contributes to the color
small amadori compound
contributes to the flavor
caramelization reaction
sugar + heat
non-enzymatic means
they require thermal energy
a Maillard reaction requires
a reducing sugar, an amino acid, and a source of high thermal energy
how can a monomeric sugar be converted into a reducing sugar
thermal degradation, and exposure to an alkaline environment
temperature for a caramelization reaction
160-180C
temperatures for a Maillard reaction
100-140C
Cast iron is a good insulator
true
ceramics are good for non stick
true
stainless steel is
good conductor poor insulator
aluminum is non stick
false
aluminum is good conductor poor insulator
true
glass is
a good insulator
conduction
transfer of thermal energy from a heat source
convection
transfer of thermal energy from a heat source via moving fluid
radiation
transfer of thermal energy directly to energy source
