Fruits and vegetables that fail to conform to an aesthetic standard are labelled suboptimal and are often devalued and ultimately discarded. Although consumers perceive suboptimal produce negatively, little is known about how these perceptions are formed and indeed the socialisation process behind them. Using 11 focus group discussions with New Zealand children aged 5–11 years (N = 97), this study explores these socialisations. The results show that family practises around growing and repurposing suboptimal produce, learning about suboptimal produce waste, and acting on that knowledge when making produce choices, facilitates the acceptance of suboptimal produce. Alternatively, observations of parents' produce choice behaviours, and parents' instructions or norms for choosing, preparing, and eating produce socialise the rejection of suboptimal produce. The implications of the study show how environmental sustainability with respect to the food waste problem could be effectively addressed if public policy moves towards strategies that “normalise” suboptimal produce. The interventions recommended show how public campaigns would be more effective by targeting children, who are not only concerned about environmental sustainability, but also through their growing agency and positive pester‐power may influence households to reconsider how food is valued.

Children's perceptions of suboptimal fruits and vegetables have not been studied in the suboptimal foods domain. Using two qualitative research methods, this study investigates children's (N = 97) edibility perceptions of suboptimal produce with varied appearance defects. The results show that unlike adult samples previously studied, children are more accepting of suboptimal produce. Defects in shape, size, and certain colour defects were positively perceived, reflecting retailers' opportunities to market suboptimal produce. High levels of brown discolorations and superficial blemishes were not acceptable, implying that produce with such defects could be repurposed as ingredients in foods prepared and sold in-store. These implications reflect retailers' opportunities in marketing suboptimal produce to children, who by their familial influence may also be able to get families to buy and consume suboptimal produce. The importance of familiarity in improving suboptimal food acceptance is also recognised for future research to explore.
