Embodiment 1

[0028] The preparation of embodiment 1 pomegranate original juice

[0029] (1) Use fresh pomegranates as raw materials, wash them, peel them, remove their seeds, put them in a juicer, and beat them.

[0030] (2) In order to prevent the color change of pomegranate juice during processing, 0.4% citric acid was added as a color-protecting agent.

[0031] (3) Filter the pomegranate juice with a double filter to separate the juice and pomace, and collect the filtrate.

[0032] (4) In order to fully hydrolyze the pectin substance, add 0.1% pectinase to the filtrate, and treat it at 50°C for 3 hours, the colloidal substance loses its protection and precipitates, playing a clarification role.

Embodiment 2

[0033] The preparation of embodiment 2 pomegranate peel extract

[0034] (1) Take fresh pomegranate peel, wash, remove stems, dry at 50°C, crush, pass through 100 mesh, prepare pomegranate peel powder, and store in a brown bottle.

[0035] (2) Take 20g of pomegranate peel powder, mix it with 60% (v / v) ethanol according to the solid-to-liquid ratio of 1:30, extract at a temperature of 40°C for 5 hours, and filter to obtain the pomegranate peel extract.

[0036] (3) Evaporate and concentrate the above extract at 40°C, and dry to obtain the pomegranate peel extract.

Embodiment 3

[0037] The mixed preparation of embodiment 3 pomegranate health drink

[0038] (1) Mix 15g of the prepared pomegranate peel extract, 550mL of pomegranate juice, and 42g of xylitol, add water to 1L, mix, and stir evenly;

[0039] (2) Use a high-pressure homogenizer to perform strong shearing, impact and cavitation on the mixed liquid under high pressure, so that the solid particles in the mixed liquid are ultrafine;

[0040] (3) Since the pomegranate beverage is mixed with a large amount of oxygen during the mixing process, oxidative browning will occur, so it is degassed at a temperature of 70°C and a vacuum of 0.08MPa;

[0041] (4) The processed pomegranate juice is put into 200mL glass bottles by the filling machine, and the bottle mouth is sealed. Sterilize at 90°C for 30 minutes, and then cool to 40°C, which is the finished product 1.

[0042] According to the same conditions as above, the pomegranate drink is prepared without adding the pomegranate peel extract, which i...

Abstract

The present invention discloses a method for preparing a health care beverage by using waste pomegranate bark, and belongs to the technical field of food. According to the present invention, a pomegranate bark extract, a pomegranate juice and xylitol are mixed to prepare the health care beverage, wherein per liter of the obtained health care beverage contains 10-20 g of the pomegranate bark extract, 400-600 mL of the pomegranate juice, and 30-60 g of the xylitol, the total flavone content is 1.361-2.149 mg / mL, and the ellagic acid content is 0.116-0.212 mg / mL; and the pomegranate bark is regarded as waste, with the present invention, problems of pomegranate bark discarding, resource waste and environmental pollution during a pomegranate processing process are solved, and the problem that the health care function of the pomegranate juice is not prominent is solved such that the pomegranate bark extract-containing health care beverage has characteristics of multiple health care functions, good taste, and body building.

Description

technical field [0001] The invention relates to a method for preparing a health drink from discarded pomegranate peels, which belongs to the technical field of food. Background technique [0002] The pomegranate is a fruit that is picked from a shrub or small tree and grown in subtropical or tropical regions. Pomegranates are native to Russia, Iran, Afghanistan, and Turkey, and later spread westward to countries along the Mediterranean Sea, and eastward to India and China. [0003] The edible part of pomegranate accounts for about 10% of the pomegranate, which is squeezed to obtain the original pomegranate juice, which is rich in nutrients such as sugar, acid, vitamins, pectin, and tannin. According to the "Compendium of Materia Medica", pomegranate has the functions of digestion, digestion, detoxification and thirst quenching, beauty and health care. Modern medical research shows that pomegranate juice also contains a variety of active substances, such as anthocyanins tha...
