摘要
The impact of heat processing and emulsifier addition on the interaction of vanillin and sodium caseinate and whey protein isolate was examined in a model system. Free vanillin in the protein drink was evaluated by a sensory panel and HPLC. Sensory analysis indicated that emulsifier, heat x protein, and heat x emulsifier affected perception of vanillin flavor. Analysis of free vanillin by HPLC indicated only a significant protein effect, with sodium caseinate interacting more with vanillin than did whey protein isolate. No correlation was found between sensory and HPLC results.
