additional information | Actinidia deliciosa | digestibility of kiwifruit allergens, actinidin (Act d 1) and thaumatin-like protein (Act d 2), is assessed using an in vitro digestion system that approximates physiological conditions with respect to the passage of food through the stomach into the duodenum: Act d 1 precipitates in simulated gastric fluid at pH 2 and digestion of the aggregated protein proceeds slowly. The residual precipitate redissolves completely in simulated duodenal fluid at pH 6.5 and is partially digested. Act d 1 and Act d 2 display nearly unchanged IgE binding abilities | ? | - |
