The Effects of Inlet Air Temperature Effects on Survivabiliy and Pysicochemical Properties of Spray-Dried Pediococcus Acidilactici

---

Recently, Pediococcus acidilactici has gained interest in research studies due to its potential probiotic properties. However, it has low survivability during digestion and short shelf life. Spray drying is widely used as a food preservation method, ensuring a stable and extended shelf-life of probiotics. At the same time, the use of spray drying is associated with several stresses, including heat, osmotic, and desiccation, which could compromise cell’s viability. Although Pediococcus acidilactici is thermotolerant, the effect of spray drying on P. acidillactici’s viability has not been investigated. Through this study, spray drying under different inlet air temperatures was performed to investigate its effect on P. acidilactici viable cells during spray drying, gastrointestinal simulation, and storage with further analysis on its physicochemical properties. Spray-dried P. acidilactici produced at 120℃ showed the highest encapsulation efficiency (91.59 ± 0.01%), moisture content (6.80 ± 0.92), and water activity (aw 0.29 ± 0.04). However, it has the lowest survivability during storage (78.61 ± 8.63%) and powder yield (58.97 ± 0.03%). In terms of survivability during gastrointestinal conditions, spray-dried P. acidilactici produced at 150℃ showed highest survivability (91.1 ± 2.96%). However, inlet air temperature has no effect (P > 0.05) the viability of spray-dried P. acidilactici during storage. This study suggested that inlet air temperature of 150℃ as a desirable parameter as such temperature resulted with high encapsulation efficiency and survivability in gastrointestinal conditions and shelf-life of spray dried P. acidilactici.
