Problems solved by technology

[0008] 2. This method takes about 20 days to extract anthocyanins from berry, and the production efficiency is low
[0009] 3. Since it takes a long time to extract anthocyanins, during the extraction process, the anthocyanin components will be destroyed, that is, under the action of anthocyanin pigment destroying enzymes, the anthocyanin components will be destroyed to produce silver glycosides Harmful substances
[0010] 4. The PH value of fresh berry crushed liquid is in the range of 3.5 to 5.0, but adding excipients wit

example 1

[0065] Pick 20kg of fresh berries, freeze them immediately at -20°C to -40°C, preferably at -20°C to -30°C, and crush them in a grinder under nitrogen flow, and put them into the grinder at -10°C to Indirect cooling water that can be circulated at 5°C, then add 3kg of edible citric acid to the berry liquid, then stir evenly, adjust the pH value to 1.0, then put the berry liquid after the pH value adjustment into the ultrasonic extractor, put Add 50% to 95% (volume) edible alcohol, preferably 40kg of 95% (volume) edible alcohol, use ultrasonic frequency of 30kHZ to extract for 3 hours / 2 times, and use a 149μm filter to carry out the total extract Filter, and the filtrate is placed under a nitrogen flow at a temperature below 10° C., and concentrated under a pressure of 40 to 70 cmHg to obtain 250 g of 20% benchmark berry concentrate.

example 2

[0067] Put the berry concentrate made by the method of Example 1 into rapid freezing at -20°C to -30°C, then put the frozen berry liquid into a freezing dehydrator equipped with far-infrared irradiation, and freeze the far-infrared berry liquid of the dehydrator. The wavelength is 2.5-20μm, and then the freeze-dehydrator is kept at a pressure of 0.5-0.05mmHg, and the temperature is kept below -50°C for freeze-dehydration and drying; when the moisture content of the dehydrated berry concentrate becomes below 5%, the dehydration stops and the The dehydrated matter is pulverized in a pulverizer, and indirect cooling water that can be circulated at -10° C. to 5° C. is fed into the pulverizer. After pulverization, 50 grams of frozen and dehydrated berry concentrate dehydrated powder with a size of 0.04 to 0.3 mm are obtained.

example 3

[0069] In the berry concentrated solution made in example 1, put into excipient, excipient adopts cyclodextrin, under the benchmark that cyclodextrin content accounts for 20% of berry concentrated solution, berry concentrated solution and cyclodextrin After mixing them at a ratio of 10:2, put the mixture of berry concentrate and cyclodextrin into the environment for rapid freezing at -20°C to -30°C; then put the frozen berry concentrate and cyclodextrin mixture into In the freezing dehydrator equipped with far-infrared irradiation, the far-red wavelength as the freezing condition should be 2.5-20 μm at this time, the freezing dehydrator is under the pressure of 0.5-0.05mmHg, and the temperature is kept below -50°C for dehydration. When the moisture content of the dehydrated product reaches below 5%, the dehydration stops, and then the dehydrated product is put into a pulverizer for crushing, and the indirect cooling water that can be circulated at -10°C to 5°C is passed into th...

Abstract

The invention discloses a manufacturing method of aronia melanocarpa dehydrated powder, comprising the following steps of: (1) quickly freezing an aronia melanocarpa fresh fruit at minus 20 to minus 40 DEG C; (2) pulverizing at minus 10 to minus 5 DEG C; (3) adding edible citric acid to adjust the pH value to be 1.0-3.4; (4) adding 50-95% edible alcohol and extracting at an ultrasonic wave of 20-30 kHz; (5) filtering and concentrating under nitrogen gas flow to obtain an aronia melanocarpa concentrated solution; (6) adding cyclodextrin and quickly freezing at minus 20 to minus 40 DEG C; (7) placing the frozen aronia melanocarpa concentrated solution into a freezing dehydrator irradiated by a far infrared ray, and freezing and dehydrating at minus 50 DEG C; and (8) after the water content of an anhydride reaches below 5%, pulverizing to obtain the aronia melanocarpa dehydrated powder in the size of 40-350 microns. The invention also discloses the aronia melanocarpa dehydrated powder manufactured by the method and flour containing the powder. The manufactured aronia melanocarpa dehydrated powder has bright color, high anthocyanin-containing content, short production cycle and favorable wholesomeness, processability and storability.

Description

technical field [0001] The present invention relates to a method for producing health food powder, in particular to a method for producing dehydrated berry powder containing high-content anthocyanins; the present invention also relates to dehydrated berry powder and flour containing dehydrated berry powder . Background technique [0002] Modern high-speed development of machine civilization has brought various environmental pollution, such as excessive viewing of TV, excessive use of personal computers and various electronic entertainment machines, fast food, nutritional imbalance caused by excessive hunger, and people suffering from mental stress. Urban people, especially drivers, test takers, computer users, etc., are prone to excessive eye fatigue, or night operations, etc. are also prone to vision loss. In order to prevent vision loss, people generally look for medical supplies or natural foods. Among them, anthocyanins are extracted from berry as the main component and...
