In Brazil, food and nutrition units (UANs) represent a type of cafeteria that is being adopted by companies with greater and greater frequency as a way to feed employees and, in the process, to offer comfort and food safety. In these units, food waste may occur at every stage of the meal production process. The goal of this study was to evaluate the amount of cooked food waste at two UANs. A two-phase case study was performed at a private company in the Brazilian state of São Paulo. The company possesses UANs located on company grounds, and Units C and D were chosen for the food waste study. During Phase 1, the descriptiveexplanatory case study involved a quantitative preliminary data analysis of the following response variables: per-capita cooked unserved food in the all-you-can-eat section (in Kg), per-capita cooked unserved food from the individual dishes available (in Kg), edible plate waste (in Kg), and the total amount of food consumed (in kg). Data was collected from Unit C on weekdays (Mondays through Fridays) from May through July, for a total of 42 days. Univariate analyses were performed based on descriptive statistics. Student's t-test was used to compare the two independent samples and paired samples. Analysis of variance was used to compare averages. Tukey's multiple comparison test was also used. A 10% significance level was adopted for the statistical tests. In Phase 2, a planned experiment involving three factors was performed in Unit D. Factor A was the lipid content of the food offered (with ranges from 25.3% to 29.9%, from 30% to 34.9%, and from 35% to 40.4%). Factor B was the way in which menu items were served (foods served in an all-you-can-eat style and then as individual dishes or foods served as individual dishes and then in an all-you-can-eat style), and factor C was meal cost based only on food categories (with ranges from R$ 2.29 and R$ 2.70 and from R$ 2.71 to R$ 2.94). The experimental design was 3x2x2 with ...
