Description of atmospheric freeze-drying process of organic apples using thermo-physical properties

Abstract

This study discusses the influence of temperature and total moisture content on ice fraction in organic apples during atmospheric freeze-drying process. The ice formation of glass transition events were described by Clausius-Clapeyron and Gordon Taylor equations. The obtained data is essential for design the drying process and for understanding the limiting factors.Keywords: ice fraction, organic apples, atmospheric freeze/drying, glass transition
