Embodiment 1
[0022] (1) Select fresh dragon fruit, peel it, beat it, and pre-cook it with steam for 10 seconds;
[0023] (2) Add 9 times of dragon fruit weight deionized water, adjust the pH value to 4.0, raise the temperature to 38°C, add 1.2% compound enzyme of dragon fruit weight, enzymolysis 120min, the compound enzyme is that the weight ratio is 5: 3:2 mixture of cellulase, pectinase and pepsin;
[0024] (3) the dragon fruit slurry after the enzymolysis is double-filtered, clarified, and centrifuged to obtain the dragon fruit original juice with a 300-mesh filter screen;
[0025] (4) adopt UHT sterilization, fill, make dragon fruit liquid.
Embodiment 2
[0027] (1) Select fresh dragon fruit, peel it, beat it, and steam it for 12 seconds;
[0028] (2) Add 10 times of dragon fruit weight deionized water, adjust the pH value to 4.2, raise the temperature to 40°C, add 0.9% compound enzyme of dragon fruit weight, enzymolysis 140min, the compound enzyme is that the weight ratio is 5: 3:2 mixture of cellulase, pectinase and pepsin;
[0029] (3) double filter the dragon fruit slurry after enzymolysis, use a 330 mesh filter screen, clarify, and centrifuge to obtain the dragon fruit original juice;
[0030] (4) adopt UHT sterilization, fill, make dragon fruit liquid.
Embodiment 3
[0032] (1) Select fresh dragon fruit, peel it, beat it, and steam it for 15 seconds;
[0033] (2) Add 11 times of the weight of dragon fruit deionized water, adjust the pH value to 4.5, raise the temperature to 42°C, add 0.7% compound enzyme of dragon fruit weight, enzymolysis 160min, the compound enzyme is that the weight ratio is 5: 3:2 mixture of cellulase, pectinase and pepsin;

Abstract
The invention belongs to the technical field of preparation of drinks and in particular relates to a method for preparing dragon fruit liquid. The method comprises the following steps: selecting fresh dragon fruits, removing the peels, pulping and precooking; performing complex enzyme enzymolysis, wherein the complex enzyme refers to a mixture of cellulase, pectinase and pepsase; performing duplex filtration, clarifying, performing centrifugal separation, thereby obtaining the raw dragon fruit juice; and sterilizing by adopting UHT, and canning, thereby obtaining the dragon fruit liquid. According to the preparation method disclosed by the invention, the preparation process is simple, macromolecular substances are decomposed into small molecules by virtue of the enzymolysis process, and the nutritional ingredients of the prepared dragon fruit liquid are easily absorbed by the human body. Moreover, the dragon fruit liquid does not contain any additive, canesugar is not manually added, and the requirements of people on low-calorie low-sugar drinks are met.
Description
technical field [0001] The invention belongs to the technical field of beverage preparation, in particular to a preparation method of dragon fruit liquid. Background technique [0002] Dragon fruit (Latin name: Hylocereus undulatus Britt), also known as red dragon fruit, dragon fruit, fairy honey fruit, jade dragon fruit. Dragon fruit not only tastes sweet, but also has high nutritional value. The main nutrients include protein, dietary fiber, vitamin B2, vitamin B3, vitamin C, iron, phosphorus, calcium, magnesium, potassium, etc. Rich in a large amount of pulp fiber, rich in carotene, vitamins B1, B2, B3, B12, C, etc., the core (black sesame seeds) is also rich in calcium, phosphorus, iron and other minerals and various enzymes, Albumin, fiber and high concentration of natural pigment anthocyanins (especially in red meat), flowers, stems and buds have various effects like their close relatives (aloe vera). Dragon fruit combines the advantages of fruit, flower buds, vegeta...
