Concentration of citrus fruit juices in membrane pouches with solar energy Part 2 : How solar drying setup and juice pretreatment determine the microbiological quality
The aim of this study was to investigate how solar drying setup and choice of juice pretreatment determine the microbiological quality in a fruit juice concentration process called solar assisted pervaporation (SAP). With this process, hygienic membrane pouches and solar energy are used to concentrate and preserve fruit juices. In this study, citrus (tangerine) marmalades were produced with SAP me
