Implementing Topological Data Analysis for Monitoring Mass Transfer during Vacuum-Assisted Osmotic Dehydration of Apples.

ABSTRACT: This study applies topological data analysis (TDA) to real-time experimental images of grape juice impregnation in apple samples with the goal of monitoring and quantifying the evolution of mass transfer under different processing conditions. We monitored the effective diffusivity (D) of water, solutes, and biocompounds during osmotic procedures using 40, 50, and 60 °Brix grape juice concentrate (GJC) by computing a topological descriptor of the real-time images known as the Euler characteristic curves (ECC). Osmotic procedures were osmodehydration (OD, absolute pressure, P _abs = 598 mmHg) and OD assisted with vacuum (ODVP, P _abs = 498 mmHg/10 min). The modified slope method for cubic geometry estimated D considering shrinkage and time evol
