Background
Milk tea is one of the most popular beverages today. Milk tea is of various kinds. Such as indian milk tea, known for adding a special flavor of mosala; the silk stocking milk tea in hong Kong area and the pearl milk tea in Taiwan area have unique characteristics. The milk tea has double nutrition of milk and tea, is one of the common food, and is popular in the world. The milk tea varieties comprise milk tea powder, ice milk tea, hot milk tea, sweet milk tea, salty milk tea and the like.
