Sobre IBD

Praca ta pokazuje, w jaki sposób badano oleje roślinne z rzepaku, kukurydzy, oliwek, słonecznika i soi, w stanie naturalnym i pod wpływem stresu termicznego. Zastosowanie NMR wodoru okazało się niezbędne w kontroli jakości olejów roślinnych, ponieważ pozwoliło określić wskaźnik jodu, średnią masę cząsteczkową (PM) triacyloglicerolu, stopnia nienasycenia i stanu utlenienia oleju w stanie naturalnym i po dowolnym czasie podgrzewania, co przy użyciu tradycyjnych metod fizykochemicznych byłoby trudnym i niedokładnym zadaniem w wielu punktach procesu analizy jakości. Również NMR C13 okazało się bardzo przydatne, ponieważ wykazało znaczące różnice w profilu węgla C13 olejów naturalnych i poddanych stresowi termicznemu. Wyniki pokazują, że techniki spektroskopowe są obecnie niezbędnymi narzędziami w kontroli jakości olejów roślinnych.
