Probiotics, by definition, are living microorganisms which when administered in adequate amounts confer a health benefit on the host. It has long been suggested to be health beneficial with effects like prevention of AAD (antibiotic associated diarrhoea)[1], increase HDL in blood[2], and when prescription of antibiotic has interrupt microbial balance in the gastrointestinal tract, probiotic may be able to restored the balance[1]. Nowadays, people have increased awareness of probiotics’ importance for health, the demand from the market thus rise and various production techniques are employed. In order for the probiotics to maintain their effectiveness all though their shelf-life, they need to be dried into pallets or powder before releasing into the market. Spray, freeze, vacuum and fluid bed drying are four major ways[3]. However, stress would be induced during the drying process and will severely affect the viability and thus the effectiveness of probiotics after rehydration.
