Abstract

The present invention discloses a preparation method of sea-buckthorn freeze-dried powder. The preparation method comprises the following steps: removing impurities from fresh sea-buckthorn fruits with branches and conducting cryopreservation; taking out the sea-buckthorn fruits with branches, separating the fruits and branches by adopting a fruit removing machine, conducting cleaning, removing impurities, conducting unfreezing by microwaves, and then crushing, pulping and deseeding the sea-buckthorn fruits to prepare sea-buckthorn raw pulp; transferring the sea-buckthorn fruit raw pulp into asterilization tank, carrying out an ultrahigh-temperature instantaneous sterilization treatment, and freezing the sterilized sea-buckthorn fruit pulp to obtain sea-buckthorn fruit pulp frozen blocks;and conducting vacuum freeze-drying on the sea-buckthorn fruit pulp frozen blocks and crushing to obtain sea-buckthorn freeze-dried powder. The product prepared by the preparation method of the sea-buckthorn freeze-dried powder is convenient to transport and store, the original nutritional ingredients and flavor of the sea-buckthorn raw pulp are kept to the maximum extent, the storage life of theproduct is prolonged, problems of seasons and regions can be solved to a certain extent, and the processing and utilization degree of the sea-buckthorn is improved.

Description

technical field [0001] The invention belongs to the technical field of food deep processing, and more specifically relates to a preparation method of seabuckthorn freeze-dried powder. Background technique [0002] Seabuckthorn is a deciduous shrub belonging to the family Echinacea, which belongs to the genus Seabuckthorn. It is characterized by drought resistance, wind and sand resistance, and can survive on saline-alkali land. desert greening. Seabuckthorn fruit is rich in nutrition. It has been determined that the fruit contains various vitamins, fatty acids, trace elements, linolein, seabuckthorn flavonoids, superoxide and other active substances and various amino acids needed by the human body. Among them, the content of vitamin C is extremely high. In every 100 grams of fruit juice, the content of vitamin C can reach 825-1100 mg, which is 2-3 times that of kiwi fruit. It is known as the king of vitamin C. It contains 7.5%-10% sugar and acid 3%-5%. [0003] Seabucktho...
