2.2.2. Green beans sampling
Sampling of green beans was separated into two parts: the first one was dedicated to the evaluation of the impact of each step of the process on folates contents. With this first sampling (2 cultivars, 5 lots), the green beans were followed along the industrial chain (Fig. 2). The second sampling was totally independent from the first one. It aimed at evaluating the dispersion of folates contents in different raw materials (5 cultivars, 11 batches) and final products (4 cultivars, 9 batches) during the harvest and production period for the canned green beans, independently from the impact of individual process steps.
