The invention relates to a low-
sugar fruit juice beverage and a production process thereof, and the production process of the low-
sugar fruit juice beverage comprises the following preparation steps: S1,
raw material pretreatment; s2, mixing ingredients; s3, blending core components; s4, dispersing a stabilizer; s5, performing homogenizing treatment; s6, sterilizing and cooling; s7, filtering and filling; the composite granules and the composite
sol are added into a low-
sugar formula, a natural functional component and
dietary fiber dual
nutrition system is constructed, and the composite granules take high-purity natural
theanine as a core material and are embedded by a
fructan wall material, so that the effects of soothing nerves and improving sleep are reserved, and reaction with other components is avoided; the composite
sol is derived from blueberry
pomace and
celery juice, is rich in natural dietary fibers, can overcome the defects that traditional low-sugar
fruit juice is single in
nutrition, insufficient in function and the like, and all functional components are natural sources and accord with the clean
label consumption trend that the components are extremely simple, natural and traceable.
