The invention relates to the technical field of
processing fruit and vegetable paste, in particular to a method for preparing concentrated red
beet juice by using a multi-
enzyme preparation. The method is prepared through the following steps of: firstly, breaking red beets, heating the broken red beets, storing the heated red beets, squeezing juice from the stored red beets, performing first Pasteur sterilization, adding the multi-
enzyme preparation for enzymolysis, then performing
ultrafiltration and concentration, performing
filtration, performing secondary Pasteur sterilization, and performing sterile filling. According to the method disclosed by the invention, through the synergistic reaction of the steps, the
nutrient components of the red beets can be reserved to the maximum extent, and the concentrated red
beet juice is high in
nutrient value; after being diluted, the concentrated red
beet juice has the taste and the fragrance of the red beets, is good in mouth feel, convenient to eat, and long in storage time, and provides raw materials for preparing powdery red beet
pigment.
