2.3. Visual quality assessment
Visual quality was examined in accordance with the sensory evaluation standards (Ma et al., 2010). The overall visual quality was evaluated on a 9–1 scale, with 9 as freshly cut, equaled to excellent, with no defects; 7 as very good, with minor defects; 5 as fair, with moderate defects; 3 equaled poor, with major defects; and 1 indicated inedible. A score of 5 was considered the limit of salability and shelf-life was defined at the days required to reach a score of 5.
