Embodiment 1

[0048] A spleen-invigorating and appetizing hawthorn pear juice and a preparation method thereof comprises mixing 50 parts of hawthorn juice and 100 parts of pear juice and homogenizing for 30 minutes at a pressure of 20-30 MPa and a temperature of 20-30°C. The homogenized hawthorn pear juice is continuously deoxygenated by a vacuum degasser at a vacuum degree of 0.09MPa and a temperature of 25-30°C to prevent the oxidation of nutrients such as vitamins. PEF non-thermal sterilization is adopted, and the parameters of PEF non-thermal sterilization are: electric field frequency 200Hz, electric field strength 35-50kv / cm, processing time 240μs, temperature 30℃-40℃, which can avoid non-enzymatic browning and flavor caused by thermal sterilization material loss.

[0049] The preparation method of hawthorn juice comprises the steps:

[0050] ① Hawthorn pretreatment: select fresh hawthorns that are fully mature and bright red in color, soak them in a salicylic acid solution for 5 min...

Embodiment 2

[0063] Add 8 parts of stomach-nourishing porous prebiotic balls to the raw materials of Example 1, mix them with hawthorn juice and pear juice, homogenize, degas, sterilize, fill and pack.

[0064] The preparation method of the stomach-nourishing porous probiotic ball is:

[0065] ①Preparation of Bifidobacteria culture solution: B. Longum bacteria solution was inoculated in MRS medium, cultured anaerobically at 37°C for 12h after nitrogen filling, and centrifuged at 4°C and 6000r / min for 10min. After decanting the supernatant, the cell pellet was washed twice with 0.85% normal saline and resuspended in normal saline, and the cell concentration was adjusted to 2×10 9 CFU ml.

[0066] ②Preparation of bacterial complex solution: 6 parts of bifidobacterium culture solution, 1 part of lactococcus oligosaccharides (mainly including stachyose and raffinose), 2 parts of soybean oligosaccharides, 1 part of konjac gum hydrolyzate, 1 part of liver juice , 1 part of coconut milk, 2 part...

Abstract

The invention relates to a method for preparing spleen strengthening and appetite promoting fructus crataegi and snow pear juice. The method includes uniformly mixing 50-60 parts of fructus crataegi juice and 100-120 parts of snow pear juice with each other and then carrying out homogenization, degassing, sterilization and filling and packaging. The method has the advantages that the fructus crataegi juice is prepared by the aid of operation such as salicylic acid soaking and preliminary storage, baking and roast smoking heating softening, primary enzymatic hydrolysis deacidification and secondary enzymatic hydrolysis fructus crataegi flavone glycosylation, accordingly, spleen strengthening and appetite promoting active components such as polyphenol and flavone in fructus crataegi can be accumulated, the antioxidant activity and the stability can be enhanced, flavor substances can be released, the mouth feel can be improved by means of maslinic acid content adjustment and the like, andflavor and nutrition of the fructus crataegi juice can be reserved to the greatest extent; the snow pear juice is prepared by the aid of pulse type ultrasonic synergistic high-oxygen pretreatment, ultrasonic catalytic micro-nano ozone bubbly water cleaning, ultrahigh-pressure water jet cutting and crushing and low-temperature modified atmosphere type juicing technologies, accordingly, purification, sterilization and browning prevention can be efficiently carried out, the problem of browning during the traditional snow pear juice preparation and the difficult problem of severe loss of nutrients such as vitamin and carotene can be solved, and flavor and nutrition of the snow pear juice can be reserved to the greatest extent.

Description

technical field [0001] The invention belongs to the field of food, and relates to the processing technology of pear beverage, in particular to a hawthorn pear juice for invigorating the spleen and appetizing and a preparation method thereof. Background technique [0002] The organic acid content in hawthorn fruit is generally more than 6%. Directly squeezing the juice and drinking it has a strong sour taste, which greatly affects the taste of hawthorn juice. Processing into fruit juice is generally limited to considering physical and chemical indicators such as sugar-acid ratio, and less consideration is given to nutritional and functional components such as flavonoids and polyphenols. Sydney juice generally has the problems of improper matching of sweetness and sourness and easy precipitation of suspended particles. Pears and hawthorns can solve the problem of sweet and sour combination. In addition, it can also provide a product that invigorates the spleen and appetizers ...
