Hong Kong-style milk tea is one of the signature beverages in Hong Kong. The quality and flavour of the milk tea greatly depends on the degree of astringency, which is in turn determined by the amount of tannins used that give a bitter aftertaste. Ultrasound-assisted Extraction (UAE) can be adopted in the milk tea brewing process to control the concentration of tannins and adjust the astringency of milk tea, thereby producing the Hong Kong-style milk tea that fits the flavour preferences of people in different regions.
