Abstract

Abstract Protein denaturation during spray drying is critical for high-quality food powders. This study investigated the influence of particle size on protein denaturation using phycocyanin as a marker. The effect of particle size was investigated at three different air outlet temperatures, with the inlet air temperature held constant. For each temperature combination, different nozzles were utilized to obtain varying particle sizes. Denaturation increased with higher outlet air temperature and larger particle size, up to a size of 40 μm. This increase in denaturation with particle size was attributed to faster drying rates and the absence of denaturation once particles are dry. Particle size had a similar magnitude of effect as outlet air temperature. For larger particles, a plateau in denaturation was observed due to a prolonged constant drying rate regime. It can be assumed that conditions that retain phycocyanin are also suited for the retention for less thermolabile proteins.

期刊介绍: Drying Technology explores the science and technology, and the engineering aspects of drying, dewatering, and related topics. Articles in this multi-disciplinary journal cover the following themes: -Fundamental and applied aspects of dryers in diverse industrial sectors- Mathematical modeling of drying and dryers- Computer modeling of transport processes in multi-phase systems- Material science aspects of drying- Transport phenomena in porous media- Design, scale-up, control and off-design analysis of dryers- Energy, environmental, safety and techno-economic aspects- Quality parameters in drying operations- Pre- and post-drying operations- Novel drying technologies. This peer-reviewed journal provides an archival reference for scientists, engineers, and technologists in all industrial sectors and academia concerned with any aspect of thermal or nonthermal dehydration and allied operations.
