The invention discloses a
processing method for a
sugar-free blueberry juice. The
processing method comprises the steps of sorting, juice squeezing, enzymolysis,
enzyme deactivation, clarification, filtering, absorption,
fermentation, distilling and proportioning. According to the
processing method, natural
aroma components and
nutrient contents of the
sugar-free blueberry juice are preserved, and the damage to
anthocyanin in the blueberry juice caused during a fermenting or heating process is reduced, so that artificial flavors and artificial pigments do not need to be added into a finished product, the juice is health, and the
sugar content of the blueberry juice is greatly lowered, so that a drinker has no
caloric intake burden, and the sugar-free blueberry juice belongs to a healthcare beverage. As trace
flavor substances such as
lactic acid and glycerin or esters which do not originally exist in blueberry fruits can further be generated in fermenting and sugar removing processes, the sugar-free blueberry juice is mellow and harmonious in mouth feel and rich in
nutrition.
