Using a novel spiral-filter press technology to biorefine horticultural by-products: The case of tomato. Part I: Process optimization and evaluation of the process impact on the antioxidative capacity Research Institute for Agriculture, Fisheries and Food Ghent University
With tomato as a model crop, the use of a novel, low-oxygen spiral-filter press technology for juice production was demonstrated on pilot-scale. Our results show that a robust process could be developed with a juice yield of 82.5% which could be increased to 97.0% with an additional mild thermal pretreatment (40 °C for 3 min). A comprehensive insight was gained in the underlying mechanisms through which process parameters can affect juice yield ...
