The invention relates to the field of food beverage
processing, and discloses a
green tea compound beverage capable of clearing heat, decreasing internal heat and refreshing and a preparation method thereof, the beverage is prepared from
high fructose corn syrup, white granulated
sugar,
green coffee bean
skin, Longjing
green tea leaves,
honeysuckle, pomelo concentrated juice, a compound
acidity regulator, an
antioxidant color fixative and a compound
flavor enhancer. The method is characterized in that a step-by-step gradient extraction process is adopted, materials are sequentially fed according to the characteristics of the raw materials in a constant-temperature
system at 83-87 DEG C, and the accumulative thermal extraction duration of the
green coffee bean
skin, the Longjing
green tea and the
honeysuckle flowers is accurately controlled to be 30 minutes, 20 minutes and 10 minutes respectively. The preparation method effectively solves the problem of bitterness and
astringent taste superposition caused by mixed extraction of multiple raw materials, and is matched with a specific
flavor and acidity adjusting
system, so that the functional components of the raw materials are reserved, the bitterness is reduced, the problem that the herbal
flavor shields the fruity flavor is solved, and the composite beverage with harmonious flavor and clear and stable
layers is obtained.
