Coupling membrane processes to obtain a lycopene‐rich extract Lycopene is a carotenoid found in tomatoes and other red fruits and vegetables. It is known for its antioxidant properties, which are associated with the prevention of cancer. Raw tomatoes and tomato‐based products are important sources of dietary lycopene. This study aimed to evaluate the integration of diafiltration and reverse osmosis processes to concentrate tomato pulp and to obtain a lycopene‐rich extract with a high antioxidant capacity and a low molecular weight. Diafiltration was efficient in desalting the tomato pulp, maintaining the lycopene concentration of the tomato at the same level as the whole tomato pulp. The permeate flux of the diafiltrated tomato pulp was 29.5 L·h-1·m−2 and the concentration factor of lycopene was 2.4. Additionally, it was found that the antioxidant capacity increased at the same rate than the lycopene content. Journal of Food Processing and Preservation, Volume 43, Issue 11, November 2019, e14164.
