Background. Food waste is a global issue affecting society from environmental, nutritional, and social perspectives. In collaboration with the National Board of Preschools, fruit and vegetable waste generated during the preparation of lunch was quantified in four preschools in the Metropolitan area of Santiago in Chile.
Methods. This study was conducted in four preschools, two in the Western area of Santiago and two in the Eastern area, of which two hold environmental quality certifications. Over a five-day period, the weight of raw materials and waste from vegetables (peels) and fruit (pomace) were measured. Percentages of vegetable and fruit post-cleaning losses and waste were evaluated.
Results. Vegetable loss exceeded 20% in 31% of the preschools, primarily from carrots and potatoes. Fruit losses were higher, with pears accounting for the most significant waste, recorded in 75% of the study centers. No differences in vegetable loss was found between centers, while variations were observed for fruit. Preschools with environmental quality certifications wasted less onions (p = 0.016) but more pears (p = 0.036).
Conclusions. There is higher fruit loss than vegetable loss, with onions and tomatoes being the least wasted. Possessing an environmental quality certification does not guarantee a significant reduction in overall losses. Handling and storage conditions may play a key role in minimizing losses. Further studies are needed to provide evidence that can guide improvements in Chile's National Board of Preschools services, aiming for a more sustainable lunch preparation processes.
