| Description | Discrete choice experiment: Italian consumers (online Qualtrics panel via TGM Research, quota-representative by gender and age, Jan-Feb 2025; n = 346) chose among two options and a 'Neither' alternative on 6 cards; profiles describe pasta packages varying flour (durum / einkorn wheat), binding ingredient (eggs / yellow pea), nutritional value, quality label, environmental impact, place of production and price per 250 g. Outcome is the chosen option (opt-out allowed). |
