Predictability of consumers' food choice based on their gazing behavior using eye-tracking has been shown and discussed in recent research. By applying this observational technique and conventional methods on a specific food product, this study aims at investigating consumers' reactions associated with gazing behavior, wanting, building up expectations, and the experience of tasting. The tested food products were wafers from Austria with hazelnut, whole wheat, lemon and vanilla flavors, which are very well known in Austria and not known in Vietnam. 114 Vietnamese and 128 Austrian participants took part in three sections: The results indicate that: i) the gazing behavior parameters are highly correlated in a positive way with the wanting-to-try choice; ii) wanting to try is in compliance with the expected liking for the Austrian consumer panel only, which is very familiar with the products; iii) the expected and tasted liking of the products are highly country and product dependent. The expected liking is strongly correlated with the tasted liking for the Austrian panel only. Differences between the reactions of the Vietnamese and Austrian consumers are discussed in detail. The results, which reflect the complex process from gazing for "wanting to try" to the expected and tasted liking, are discussed in the context of the cognitive theory and food choice habits of the consumers.
