Abstract
Sposób określania bezpiecznego czasu przechowywania biokomponentu, polega na tym, że zdejmuje się za pomocą spektrometru absorpcyjnego widma próbek biokomponentu w ustalonych odstępach czasu, określa się wartość parametru krytycznego, którym jest zmiana transmisji ΔT światła w widmie absorpcyjnym biokomponentu w zakresie 200 – 1200 nm, określająca stężenie prekursorów starzenia biokomponentu, gdzie ΔT = T962 – T880, przy czym: T962-transmisja przy długości fali 962 nm [%]; T880 - transmisja przy długości fali 880 nm [%], a następnie oblicza się tgr - czas bezpiecznego przechowywania biokomponentu, według zależności tgr = (In ΔTgr - In ΔT 0)/k; gdzie: ΔT gr jest ustaloną graniczną wartością ΔT, ΔT0 jest wartością ΔT zmierzoną dla pobranej próbki przechowywanego biokomponentu, k jest stałą szybkości reakcji tworzenia prekursorów starzenia biokomponentu, której wartość wyznacza się dla każdego rodzaju biokomponentu i średniej temperatury przechowywanego produktu określając wartości ΔT w widmach absorpcyjnych w zakresie 200 – 1200 nm dla próbek biokomponentu pobieranych ze zbiornika magazynowego w ustalonych odstępach czasu, a następnie oblicza się według wzoru: k = (In ΔTn - In ΔT1)/t, gdzie: ΔT n - wartość transmisji dla próbki biokomponentu po czasie t przechowywania z n-tego pobranie ze zbiornika magazynowego, ΔT 1 - wartość transmisji dla próbki biokomponentu z pierwszego pobrania.The method of determining the safe storage time of a biocomponent consists in taking the spectra of biocomponent samples using an absorption spectrometer at set intervals, determining the value of the critical parameter, which is the change in light transmission ΔT in the absorption spectrum of the biocomponent in the range of 200 - 1200 nm, determining concentration of biocomponent aging precursors, where ΔT = T962 – T880, with: T962-transmission at a wavelength of 962 nm [%]; T880 - transmission at a wavelength of 880 nm [%], and then tgr is calculated - the time of safe storage of the biocomponent, according to the relationship tgr = (In ΔTgr - In ΔT 0)/k; where: ΔT gr is the established limit value of ΔT, ΔT0 is the ΔT value measured for a sample of the stored biocomponent, k is the reaction rate constant for the formation of biocomponent aging precursors, the value of which is determined for each type of biocomponent and the average temperature of the stored product by determining the ΔT values in the absorption spectra in the range of 200 - 1200 nm for biocomponent samples taken from the storage tank at set time intervals, and then calculated according to the formula: k = (In ΔTn - In ΔT1)/t, where: ΔT n - transmission value for the biocomponent sample after time t storage from the nth collection from the storage tank, ΔT 1 - transmission value for the biocomponent sample from the first collection.
