“…A first system, named TIM1, reproduces the stomach and small intestine (31), while the large intestine model is called TIM2 (32). In these artificial digestive systems, the main parameters of digestion (temperature, peristaltic mixing, transit time, gastrointestinal secretions, pH, and microflora activity) are reproduced as faithfully as possible, and the digestive systems have been validated by many studies (29,30,44,48).…”

“…Jak na omawiane warunki obróbki termicznej, stwierdzono wyjątkowo duże stężenie MeIQx w filecie z kurczęcia smażonym 15 min w temp. 220 ºC -wynosiło ono 10,4 ng/g [29]. Z innych danych literaturowych wynika, że spośród amin tworzących się podczas płytkie-go smażenia, stężenie PhIP jest największe [44,46,51].…”

“…The TNO gastro-intestinal tract model (TIM), a dynamic computer-controlled in vitro system that mimics the human physiological conditions in the stomach and small intestine, is more complex. It contains four compartments and has been used to study the absorption of heterocyclic aromatic amines and the degradation of gluten (Krul et al, 2000;Mitea et al, 2008). -At the point of the small intestine, absorption of substances and water become the main issue for bioavailability, although occurrence of metabolism in the intestine often has been underestimated ( Van der Kerkhof et al, 2006) and is bacterial in origin, in addition to endogenous enzymes.…”
