Varietal and trait preferences for boiled sweetpotato in urban Hanoi and implications for breeding.

Cognizant of the need to refocus breeding efforts toward end-product quality traits taking into account the preferences of consumers and in consideration of the rapid urbanization in South-eastern Asia, this study investigated the consumer's preferences for sweetpotato in Hanoi. Using a mixed-methods research design, the study identified the most preferred and least preferred attributes of both the fresh and boiled product, disaggregated by gender, age, and socioeconomic status. Preferences and associated traits of six popular varieties were determined.

Gazing behavior reactions of Vietnamese and Austrian consumers to Austrian wafers and their relations to wanting, expected and tasted liking.

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.
