Problems solved by technology

"Anhui Agricultural Science" 2007,35(16):4757-4759 discloses the research of extracting pectin from the peel of Akebia trifoliata by acid hydrolysis, and 2008,29, (01):154-17 of "Food Science" also discloses Aketobia peel pectin extraction process research, but in the above-mentioned Akebia trifoliate pectin extraction process, all adopt inorganic acid such as hydrochloric acid, sulfuric acid, nitric acid etc. to carry out acid hydrolysis and extraction, but too much sulfuric acid will produce a large amount of acid waste water, not It is beneficial to environmental protection; and during acid extraction, the raw materials are smashed and heated to form a viscous paste, which makes it difficult to filter the extract and is easy to corrode the equipment.

Embodiment 1

[0038] 1. Preparation of nanoscale carbon-based solid acid The preparation steps are as follows:

[0039] a), dissolving the six-carbon sugar in water, stirring at room temperature for 0.1-5h to form a 2mol / L aqueous solution; the six-carbon sugar is glucose;

[0040] b) Add mineral acid to the solution obtained in step a), and stir for 2-3 hours; the mineral acid is nitric acid; wherein the molar ratio of mineral acid to hexose is 3:1;

[0041] c), heat-treating the sample obtained in step b) at 90-120°C for 6-8h;

[0042] d), heat-treated samples were heat-treated at 600-650° C. for 10-12 h under nitrogen atmosphere to obtain nanoscale carbon-based solid acid.

[0043] Two, prepare Akebia trifoliate pectin extract:

[0044] 1) The peel of Akebia trifoliata washed with deionized water is dried, and then dried under reduced pressure at 40°C and a pressure of P=-0.07MPa to constant weight;

[0045]2) Crumble 10kg of dried Akebia pericarp into chunks below 0.2cm, and then pla...

Embodiment 2

[0057] The preparation method of nanoscale carbon-based solid acid is the same as in Example 1.

[0058] Except step 5) before adding ethanol, the extract was chelated with chelating agent calcium citrate and then filtered, and the filtrate was slowly dropped into ethanol to precipitate the pectin extract, and filtered and dried to obtain the rear end extract of Akebia trifoliata different from Example 1 Besides, the extraction method of the other Akebia trifoliate pectin extracts is exactly the same as in Example 1. The back-end extract of Akebia clover, namely Akebia clover pectin, is detected and calculated with reference to the teaching in "Anhui Agricultural Science" 2007, 35 (16): 4757-4759, and finally the back-end extract of Akebia clover of the present invention is Akebia clover The extraction rate of pectin is 16.2%.

[0059] To prepare akeba pectin drink:

[0060] 1) Weigh 6 parts by weight of Akebia trifoliate pectin extract and add it to 102 parts by weight of d...

Embodiment 3

[0064] The preparation method of nanoscale carbon-based solid acid is the same as in Example 1.

[0065] Except step 5) before adding ethanol, the extract was chelated with chelating agent calcium citrate and then filtered, and the filtrate was slowly dropped into ethanol to precipitate the pectin extract, and filtered and dried to obtain the rear end extract of Akebia trifoliata different from Example 1 Besides, the extraction method of the other Akebia trifoliate pectin extracts is exactly the same as in Example 1.

[0066] To prepare akeba pectin drink:

[0067] 1) Weigh 5 parts by weight of Akebia trifoliate pectin extract and add it to 100 parts by weight of deionized water, and cut it in a high-speed shearing machine at 0-5°C for 20-30 minutes;

[0068] 2) Add 0.2 parts by weight of calcium alginate, 0.2 parts by weight of riboflavin tetrabutyrate, and 0.2 parts by weight of D-(+)-N-(2,4-dihydroxy-3,3-dimethylbutyryl) -Calcium β-alanine and 0.3 parts by weight of calci...

Abstract

The invention belongs to the technical field of beverages, and specifically relates to an akebia trifoliate pectin beverage and a preparation method thereof. Nano level carbon-based solid acid is taken as the catalyst to extract peels of akebia trifoliate so as to obtain akebia trifoliate pectin extract; and then akebia trifoliate pectin extract is taken as the raw material to prepare the akebia trifoliate pectin beverage. The prepared akebia trifoliate pectin beverage contains flavonoid derivatives, which have multiple bioactivities and functions of preventing bacteria and viruses and nourishing liver.

Description

technical field [0001] The invention belongs to the technical field of beverages, and in particular relates to an akebia pectin beverage and a preparation method thereof. Background technique [0002] Plant beverages are the third-generation beverages after carbonated beverages and fruit and vegetable beverages. Compared with ordinary beverages, due to their inherent "natural, green, nutritious, and healthy" qualities, plant beverages are in line with the development trends and trends of the beverage market, and are becoming more and more popular among consumers. reader's favorite. [0003] Akebia trifoliate is an important medicinal plant, its roots, vines, fruits and seeds can be used as medicine. The pulp of Akebia clover is rich in nutrients, rich in protein, fat, starch and various soluble sugars, calcium, phosphorus, iron, organic acids, vitamins B1, BZ, B6, etc. It can be eaten fresh, brewed, and made into beverages. Akebia seeds are rich in oils and fats, with high...
