AI virtual streamers in sustainable food marketing: how expertise, interactivity, and anthropomorphism shape consumer acceptance of upcycled foods.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Drawing on the stimulus-organism-response (SOR) framework, this study examines how AI virtual streamer expertise, interactivity, and anthropomorphism influence consumers' purchase intention through perceived value and product trust. Methods: A three-wave time-lagged survey was conducted among adult consumers in China. After data screening and anonymous matching across the three waves, 392 valid responses were retained. Structural equation modeling and bootstrap analysis were used to test the hypothesized relationships and indirect effects. Results: Expertise and interactivity were positively associated with both perceived value and product trust. Anthropomorphism was positively associated with product trust, but its relationship with perceived value was not significant. Perceived value and product trust both positively predicted purchase intention. The mediation analysis showed that perceived value mediated the relationships of expertise and interactivity with purchase intention, but did not mediate the effect of anthropomorphism. Product trust mediated the relationships between all three AI virtual streamer characteristics and purchase intention. Conclusion: AI virtual streamer characteristics influence consumer acceptance of upcycled foods through different psychological pathways. Expertise and interactivity strengthen both perceived value and product trust, whereas anthropomorphism mainly supports trust formation. These findings clarify the distinct roles of AI communication cues and highlight the importance of combining clear product information, responsive interaction, and trust-building strategies in sustainable food marketing.
