Abstract

Abstract: The research assessed the influence of seven industrial lines and four harvesting periods on diced tomato quality. Soluble solids, pH, furosine, lycopene, consistency, and drained weight depended mainly on processing line, while α-tocopherol, γ-tocopherol, colour, and dice area on sampling period. Heat damage, quite similar among technologies, was highest for cold-filling applied to big cans. Lycopene content, highest in aseptic-packaging lines, was linked not to heat damage but to oxygen exposure. Ca-added samples showed lower lycopene, α-tocopherol, a */ b *, and higher consistency. Ca effect on drained weight and total dice area was minimal. Without Ca addition, consistency was highest in low heat damage samples. Highlights: Diced tomato from seven industrial lines and four harvesting periods were analysed. Processing line mainly affected furosine, lycopene, consistency and drained weight. Harvesting period mainly influenced α- and γ-tocopherol, colour, dice number and area. Heat damage was highest in cold-filled big cans; lycopene in aseptic-packaging lines. Ca decreased antioxidants but scarcely affected total dice area and drained weight.
