Embodiment 1
[0031] A high-efficiency extraction process for onion extract, characterized in that the steps are as follows:
[0032] (1) After removing the dry skin on the fresh onion, put it in water for cleaning, keep the temperature of the water at 35-45°C, remove and drain the surface water after cleaning, cut it into slices, and put it into the freezing equipment. Freeze at minus 10°C for 3-5 hours;
[0033] (2) Take out the frozen onion slices in step (1), cut them into cubes, dry the cubes with cold air for 3-10 minutes under the environment of 55-58°C, and then carry out intermittent microwave treatment on the cubes of onions. The number of times is 4 to 10 times, each interval is 40 seconds, and the microwave treatment temperature does not exceed 100°C; the effective components are separated out, which is convenient for subsequent extraction;
[0034] (3) Add the diced onion after microwave treatment in step (2) into purified water, and heat it to 45°C, then add xylanase and stir...
Embodiment 2
[0038] A formaldehyde-removing preparation containing the onion extract extracted by the process of Example 1, made of the following components by weight: 200 g of onion extract, 100 g of orange peel powder, 150 g of white vinegar, 80 g of aloe juice, and 20 g of cinnamaldehyde diethyl acetal , Soybean sprouts instant powder 50g, glutamic acid mother liquor 80g, coptis extract 20g, lotus leaf ash 40g, degummed kelp powder 50g, plant straw powder 100g, purified water 500g;
[0039] The preparation method of above-mentioned formaldehyde-removing preparation is as follows:
[0040] (1) Put orange peel powder, soybean sprouts instant powder, Coptis chinensis extract, lotus leaf ash, degummed kelp powder and plant straw micropowder into the blender, stir the dry mixture for 10 minutes, then add purified water and onion extract in turn , white vinegar, aloe vera juice, glutamic acid mother liquor and cinnamaldehyde diethyl acetal, after mixing all kinds of materials, pump them into ...

Abstract
The invention relates to a high-efficiency extraction process of an onion extract liquid. The high-efficiency extraction process comprises the following steps: (1) removing dry skin on outer surfaces of fresh onions, washing the onions in water, keeping the temperature of the water at 35 to 45 DEG C, taking out the onions after the onions are cleaned, draining the water on the surfaces of the onions, cutting the onions into slices, and placing the onion slices into a freezing device; (2) taking out the frozen onion slices, cutting the frozen onion slices into dices, drying the onion dices in an environment of 55 to 58 DEG C for 3 to 10 minutes by virtue of cold air, and then intermittently treating the onion dices by virtue of microwaves, wherein the microwave treatment temperature is not higher than 100 DEG C; (3) adding the microwave-treated onion dices into pure water, heating to 45 DEG C, adding xylanase, uniformly stirring, and extracting for 2 to 4 hours at the temperature of 45 to 60 DEG C to obtain an extract liquid; and (4) heating the extract liquid to 100 DEG C, keeping for 30 minutes, cooling, then carrying out the vacuum suction filtration by virtue of a multifunctional vacuum circulating-water pump to obtain the suction-filtered liquid, and sterilizing and filling the liquid to obtain the onion extract liquid.
Description
technical field [0001] The invention relates to the technical field of active ingredient extraction, in particular to a high-efficiency extraction process of onion extract. Background technique [0002] Onion is a vegetable with high nutritional value and medicinal value. It has been reported that onions have very good medicinal effects on arteriosclerosis, hypertension, thrombosis, and even diabetes. Although there are many varieties of onions, no matter which variety , whose main active ingredients are sulfur-containing organic compounds. The physiological effects of onions are almost all due to the effect of sulfide. The content of these physiologically active substances can reach 0.5% in fresh onions. Experiments have proved that these active ingredients in onions are stable to heat, insoluble in water, and not volatile. Therefore, use steam to distill onions, and then use ether to extract oily substances from the distillate, that is, onion extracts. The content of su...
