A Preliminary Study of Swell-Drying as an Innovative Process for Improving the Nutritional Quality of Dried Lucuma (Pouteria lucuma) and Dried Goldenberry (Physalis peruviana L.)

Lucuma and goldenberry are rich in bioactive compounds, and swell-drying (SD) can help preserve these properties. This study examined how SD impacts the nutritional quality of lucuma and goldenberry. The SD process involved the following: (1) initial pre-drying, with Interval Highly Active Drying (IHAD) for lucuma and Continuous Convective Airflow Drying (CCAD) for goldenberry, (2) a DIC treatment under an experimental design with 13 treatments, and (3) a final CCAD step. The parameters...
