Comparing the Effects of Ultra‐High‐Pressure Homogenization and Conventional Thermal Treatments on the Microbiological, Physical, and Chemical Quality of Almond Beverages

Abstract: Ultra-high-pressure-homogenization (UHPH) is an emerging technology, a potential alternative to conventional heat treatments. It is a simple process consisting of single step. When liquid food (almond beverage in this study) passes through the high-pressure valve, a very good stability and reduction of microorganisms is achieved, both effects due to the particle breakdown. Specific UHPH conditions could produce commercial sterilization of almond beverage.

“…The usual homogenization pressures range between 16-30 MPa, although some researchers are studying the use of ultra-high pressures (UHPH, >150 MPa) in vegetable milk production (Bernat, Chafer, A., & González-Martínez, 2011;N. Cruz et al, 2007;Valencia-Flores, Hernandez-Herrero, Guamis, & Ferragut, 2013). Food additives, such as emulsifiers (lecithin), stabilizers (hydrocolloids), sweeteners, either natural (sucrose, fructose or glucose syrups from agave, corn, rice or wheat) or synthetic (acesulfame K, aspartame or sucralose) and, sometimes, flavoring agents (cocoa, soluble coffee, vanilla or cinnamon) are often introduced before the homogenization step.…”

“…The most common stability problems of vegetable beverages are the creaming of oil droplets and the sedimentation of solid particles. Although UHPH-treated soy and almond milk showed high hydrophobicity values after treatment, the colloidal stability was much higher than UHT vegetable milk [52,85].…”

“…Upon UHPH treatment, the size of particles decreases, but increasing pressure and inlet temperature of vegetable milk did not produce significant variations in the particle size of UHPH-treated soy and almond milk [52,72,85]. As known, the particle size of a colloidal system is related to its stability.…”
