Embodiment Construction

[0017] Fresh peel, pomace or dried fruit meal can be used as raw materials. The fresh peel should be processed in time to avoid the hydrolysis of pectinases in the raw materials, which will reduce the yield of pectin or the degree of gelation. First crush the peel to a particle size of 2-3mm, and place it in steam or boiling water for 5-8 minutes to inactivate the activity of pectinase. The enzyme-killed raw materials are then soaked in water for 30 minutes, heated to 90°C for 5 minutes, pressed to remove the juice, and rinsed with water several times to remove bitterness, pigments and soluble impurities as much as possible. After the dry skin is soaked in warm water and rehydrated, take the same treatment as above for later use.

[0018] The pretreated raw material is made into slurry with ion exchanger and water at pH 1.3~1.6. The raw material is mixed with about 30~50 times of water first, and a certain amount of ion exchanger is added to adjust the pH value of the slurry ...

Abstract

The invention relates to a method for extracting pectin and synephrine by utilizing peels and marc. The pectin comprises three types of protopectin, water soluble pectin and pectic acid, wherein the former is not soluble in water, and the two latter are both soluble in the water. A great number of pectin components and synephrine components exist in the peels and the marc. In the invention, a pectin product is prepared by utilizing a biocatalyst without high temperature and high pressure reaction in the production process, extracting the pectin through effective bonding of acidolysis and enzyme, eliminating the destructive action of pectinase to the pectin through high temperature enzyme killing, releasing the pectin and the synephrine under an acid condition, and extracting and purifying the pectin through a subsequent extraction technology; and a synephrine product is also prepared through resin adsorption, falling film evaporation in waste liquid after the pectin product is prepared. The invention does not relate to toxic chemicals and operation under the room temperature and the normal pressure, is suitable for large scale industrialization, and can dramatically lower the production cost.
