BSPL Flashcards
what does BSPL use
intense short duration oulses of borad spectrum white light
wave length of BSPL
200-1000nm
application of pulse light
surfaces, packaging materials, air, water or salt
type of light used
UV rich (263.5nm is best)
when used for food what happens to the BSPL
UV is filtered out to prevent oxidative processing and mineral loss
describe the mechanism of inactivation
interaction between UV and DNA (changes to bases)
lysis of cell wall due to infrared heat
application of pulsed light in the food industry
sterilisation of microbial population reduction in
packaging materials
transparent pharmaceutical products
process surfaces
are enzymes effected by pulsed light plus two examples
not really
LDH and alkaline phosphotase
are enzymes effected by pulsed light plus two examples
not really
LDH and alkaline phosphotase
critical processing factors for BSPL
light (how much UV)
packaging (transparent?)
food attributes: type, transparency, colour, depth of fluid colume
why is BSPLL considered clean?
relies on electricity, no chemical residue
