Advantage and disadvantages of spray drying techniques.

Advantages	Disadvantages
The advantages of the spray drying process are ease of scaling up, low operational cost, continuous operation, and adaptability to most common industrial equipment	(i) However, spray drying may not be suitable particularly for probiotic bacteria due to requirement of high temperature drying [19, 193, 194]; (ii) The loss of viability also depends upon the type of carrier used, for example, log reduction in soluble starch found to be higher compared to other carriers such as alginate, gum Arabic, and skim milk [183, 195]
