specific Embodiment approach 1

[0017] Specific embodiment one: the extraction method of a kind of anthocyanin of present embodiment, realize according to the following steps:

[0018] 1. Crush wild blueberry fresh fruit into blueberry pulp, perform solid-liquid separation, and then cool the separated liquid to 12-17°C to obtain extract A;

[0019] 2. Break up the solid phase separated in step 1 and separate the solid and liquid, then cool the separated liquid to 12-17°C to obtain the extract B;

[0020] 3. Mix the extract A and the extract B, then add ethanol with a mass fraction of 95% to the mixture, mix well and carry out reflux extraction for 16-20 hours, filter the liquid, and then concentrate under reduced pressure to a relative density of 1.13 ~1.25 of the clear paste, cooled to room temperature, and then put into a freeze dryer, and the solid obtained after drying was made into a powder by an ultra-fine wall breaking machine to obtain a blueberry powder;

[0021] 4. Operate the fresh fruit of wild ...

specific Embodiment approach 2

[0024] Embodiment 2: This embodiment differs from Embodiment 1 in that the solid-liquid separation in Step 1 is centrifuged at a speed of 3000 r / min for 10 min. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 1, the separated liquid is cooled to 14°C. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an extraction method of anthocyanins, and relates to the technical field of food processing and extraction. The problems that an existing anthocyanins extraction method is low in extraction efficiency, complex in operation and high in cost are solved. The method comprises the steps that 1. wild blueberries are broken and then subjected to solid-liquid separation, the liquid is cooled, and an extracting solution A is obtained; 2, the separated solid is broken and subjected to solid-liquid separation, the liquid is cooled, and an extracting solution B is obtained; 3, the A and the B are mixed, then ethanol is added, reflux extraction is conducted, vacuum concentration is conducted, freeze drying and pulvering are conducted, and blueberry powder is obtained; 4, wild lonicera edulis is subjected to the above-mentioned operation, and lonicera edulis powder is obtained; 5, the blueberry powder and the lonicera edulis powder are mixed. The wild blueberries and the wild lonicera edulis are adopted, flavonoid substances contained in the wild blueberries and the wild lonicera edulis are different, a visual nervous system can be effectively repaired, antioxidation is achieved, free radicals in the body are removed, the body immunity is improved, a good auxiliary improving function is achieved for gynecological diseases, metabolism improvement is promoted, and the sleep quality is improved. The method is suitable for extracting the anthocyanins.

Description

technical field [0001] The invention relates to the technical field of food processing and extraction, in particular to an extraction method of anthocyanins. Background technique [0002] Anthocyanin, also known as anthocyanin, is a kind of water-soluble natural pigment widely present in plants in nature, belonging to flavonoid compounds. It is the main coloring substance in plant petals, and most of the colorful colors of fruits, vegetables, and flowers are related to it. As a natural pigment, anthocyanins have no toxic side effects, high safety, and natural tones; anthocyanins are effective antioxidant substances, which can improve the body's immunity and have a significant effect on scavenging free radicals, prevent skin aging, enhance blood circulation, and It can eliminate eye fatigue and delay the aging of brain nerves; the market prospect is broad. [0003] At present, the methods for extracting anthocyanins generally have the problems of low extraction efficiency, ...
