In order to assess the applicability of the method, twelve commercial fruits and vegetables were analyzed. The samples were categorized by their color, which was mainly due to their CARS and/or CHLS profiles. Specifically, orange/red (guava, watermelon and tamarillo), orange/yellow (carrot, pumpkin, papaya, physalis, corn, sweetpotato and nectarine) and green (broccoli and spinach) plant foods were considered. All the samples were acquired from local supermarkets. Upon arrival at the laboratory they were chopped and freeze-dried. In the case of the fruits, the peel and the seeds were previously removed.
