Embodiment Construction

[0026] The invention provides a preparation process of cranberry extract proanthocyanidins, a preparation process of cranberry extract proanthocyanidins, which mainly includes the following steps:

[0027] 1) Extraction: Weigh 1000g of cranberry fresh fruit, put it into a heating container after cleaning, add water with a mass 6 times the mass of cranberry fresh fruit, that is, 6L of water, heat to 80°C, and keep the temperature at 80°C Stir at ℃ ambient temperature for 2 hours, break the wall and beat.

[0028] 2) Filtration: Filter the homogeneously mixed slurry prepared in step 1) with a 200-mesh filter cloth, and leave the filtration process for 2 hours to fully filter out the filtrate and extract the desired filtrate.

[0029] 3), step 2) to filter the thick pulp after filtration, add 6L of water, repeat step 1), break the wall and beat the pulp, and extract the pulp filtrate for the second time.

[0030] 4) Adsorption: take the filtrate obtained in step 2) and step 3), ...

Abstract

The invention discloses a preparation process of cranberry extract procyanidine. The method mainly comprises the steps of extraction, filtration, secondary extraction, adsorption, desorption, concentration and purification, drying and atomization and the like; finished product processing of the cranberry extract procyanidine is completed, and the product obtained through the process is high in procyanidine content, capable of meeting market requirements, simple in process, high in operability, short in production period, low in cost and free of environmental pollution, so that the invention ismore suitable for industrial production. In the process, water is used as a solvent, the procyanidine is dissolved in the water firstly, and then resin adsorption purification and selective extraction are carried out instead of other industrial solvents such as ethanol, so that the process is safer and lower in cost; after a stability test, industrial production is carried out, and the cranberryextract produced in a workshop also achieves an expected effect.

Description

technical field [0001] The invention relates to the technical field of extraction of effective plant components, in particular to a preparation process of proanthocyanidins from cranberry extract. Background technique [0002] Cranberry, also known as cranberry, is rich in proanthocyanidins, vitamins, and various minerals. Its fruit is a red berry, which can be eaten as a fruit. The harvested fruit is used to make juice, jam, etc. At present, the commonly used storage method is hot air drying, and the skin of cranberries will turn black after hot air drying. [0003] Cranberry sauce is a traditional topping for turkey, an American Thanksgiving main course. Because the cranberry itself has a strong sour taste, the fruit juice used as a drink is generally mixed with sweeter ingredients such as syrup or apple juice. [0004] Cranberry is also a natural antibacterial and health-care fruit, and it is the best natural therapeutic food for preventing and treating various bacteri...
