Problems solved by technology

[0003] The present invention is aimed at the existing problems: while the traditional extraction process of the red pigment in red pomegranate is to squeeze the pomegranate seeds, filter and dry the pomegranate juice to obtain the pomegranate red pigment, although the extracted red pigment has Higher safety in use, however, the extracted red pigment contains sugars, vitamins and other components, the purity is relatively low, and its health care efficacy is poor, and the pulp removed by filtration still contains more red pigment components, waste of resources and costs

Embodiment 1

[0017] A kind of extraction technology of garnet red pigment, comprises the following steps:

[0018] (1) Pretreatment: Select high-quality red pomegranate varieties as the extraction raw materials, which are rich in red pigment, which can reduce the processing cost of red pigment. First, the picked pomegranates are cleaned with sodium hypochlorite solution, and the pomegranate seeds are obtained after peeling. The pomegranate seeds are crushed, Beating treatment to increase the extraction rate of garnet red pigment to obtain pomegranate slurry;

[0019] (2) Oscillation: Add water twice its mass to the pomegranate slurry, put it into an ultrasonic tank and pressurize it to 1.2Mpa, and oscillate at 46°C for 25 minutes. The increase in air density can improve the vibration and crushing effect on pomegranate pulp, so that The red pigment is separated from the combined components, and then an enzyme is added to it for enzymatic hydrolysis for 3.5 hours, which can degrade and destr...

Embodiment 2

[0028] (1) Pretreatment: Select high-quality red pomegranate varieties as the extraction raw materials, which are rich in red pigment, which can reduce the processing cost of red pigment. First, the picked pomegranates are cleaned with sodium hypochlorite solution, and the pomegranate seeds are obtained after peeling. The pomegranate seeds are crushed, Beating treatment to increase the extraction rate of garnet red pigment to obtain pomegranate slurry;

[0029] (2) Oscillation: Add 3 times the mass of water to the pomegranate slurry, put it into the ultrasonic tank and pressurize it to 1.8Mpa, and oscillate at 48°C for 27 minutes. The increase in air density can improve the vibration and crushing of the pomegranate pulp, so that The red pigment is separated from the combined components, and then enzymes are added to it for enzymatic hydrolysis for 4 hours, which can degrade and destroy the plant cell wall, promote the exudation of the red pigment components in the plant cells, ...

Abstract

The invention discloses a pomegranate red pigment extraction technology which is characterized by comprising the following steps of (1) pretreatment: selecting a high quality pomegranate variety as anextraction raw material, performing sterilization and cleaning firstly, and performing crushing and pulping treatment on pomegranate seeds; (2) oscillation: adding water in the pomegranate pulp for mixing, putting a mixture in an ultrasonic groove body for oscillation, and then adding an enzyme agent in a product for enzymolysis; (3) vacuum steaming: pouring an enzymatic pomegranate solution intoa vacuum tank, pumping the vacuum tank into a vacuum state, and performing steaming; (4) extraction: performing high-speed stirring on the steamed pomegranate solution, performing centrifugation to obtain an upper filtrate, and adding a modified activated carbon ball in the upper filtrate for adsorption; and (5) washing and drying: soaking the modified activated carbon ball with anhydrous alcoholfor washing treatment.

Description

technical field [0001] The invention belongs to the technical field of pomegranate deep processing, and in particular relates to a process for extracting pomegranate red pigment. Background technique [0002] The red pomegranate is named for its pink skin color, and the more famous ones include Yimeng red pomegranate and Lianggou red pomegranate. The former is famous for its origin, while the latter is famous for its unique processing technology and raw materials. Red pomegranate has high edible and medicinal value. Not only pomegranate seeds can be used as medicine, but also its peel, roots and flowers can be used as raw materials for medicine. It contains a variety of amino acids and trace elements, which can help digestion, soften blood vessels, and lower blood pressure. and other functions, and the various phenols and red pigments contained in it have strong anti-oxidation, metabolism promotion, and toxin discharge effects, and are often used as food additives and functi...
