specific Embodiment approach 1

[0013] Specific embodiment one: in the present embodiment, the extraction method step of indigo anthocyanin is as follows:

[0014] 1. Preparation of the crude extract of indigo anthocyanins: Weigh the frozen fresh fruit, add ethanol with a volume concentration of 60-80% at a ratio of 1kg: 2-4L solid-liquid, squeeze the juice and homogenate for 3 minutes, homogenize at 16000 rpm For 3 minutes, use a decanter centrifuge to separate the solid and liquid at a speed of 1500-2000r / min, separate the extract and residue, add the residue to the aqueous solution at a ratio of 1kg: 2-4L, and continue the low-temperature process. Homogeneous extraction and centrifugation, continuous extraction 3 times, remove the residue, and combine the extracts.

[0015] 2. Concentration: Concentrate the extract of indigo anthocyanin with a vacuum scraper film, the concentration condition is 45-50° C., and the vacuum degree is 0.1-0.15 mbar to obtain the concentrated solution of indigo anthocyanin, and...

specific Embodiment approach 2

[0017] Embodiment 2: This embodiment differs from Embodiment 1 in that in Step 1, the speed of the high-speed homogenizer is 16,000-24,000 rpm, the extraction time is 3-10 minutes, and the ethanol concentration is 60-80%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0018] Embodiment 3: This embodiment is different from Embodiment 1 and Embodiment 2 in that: the vacuum degree of the vacuum concentration process in step 2 is lower than 0.09Mpa, and the temperature is 35-45°C. Others are the same as the specific embodiment 1 and 2.

Abstract

The invention provides an extracting method of lonicera caerulea anthocyanidin and relates to an extracting process of lonicera caerulea anthocyanidin. The extracting method of lonicera caerulea anthocyanidin is provided to solve the problems that the extraction rate of lonicera caerulea anthocyanidin is low, and lonicera caerulea anthocyanidin is not high in activity. The extracting method of lonicera caerulea anthocyanidin comprises the following steps: taking lonicera caerulea samples, squeezing juice and uniformizing pulp, performing homogenizing through a homogenizer, performing solid-liquid separation, performing concentration, set volume of distilled water to the mark, and obtaining concentrated materials; adopting a vacuum scraping plate type film to concentrate lonicera caerulea anthocyanidin extraction solution, and obtaining mayberry polyphenol concentrated solution; and performing grinding after carrying out vacuum freeze-drying on lonicera caerulea anthocyanidin concentrated solution, and obtaining lonicera caerulea anthocyanidin freeze-drying powder. Lonicera caerulea anthocyanidin is obtained by adopting a low-temperature-solvent homogenizing extraction method, and high-purity and high-activity lonicera caerulea anthocyanidin extract is obtained after decompression and concentration. The extracting method of lonicera caerulea anthocyanidin is simple in process, high in extraction rate and suitable for popularization and application.

Description

technical field [0001] The invention relates to a process for extracting indigo anthocyanins. Background technique [0002] Traditional Chinese medicine calls anorexia anorexia, which is mainly due to dysfunction of the spleen and stomach. It is caused by deficiency of the spleen and stomach, or improper feeding, improper diet, and damage to the spleen and stomach. Anorexia in children is a common group of digestive disorders in pediatrics. It is aimed at long-term loss or disappearance of appetite and reduced food intake as the main symptoms. It is a common disease in children today. Sometimes hyperhidrosis, easy to Symptoms such as colds, mostly in children aged 1-6. Its characteristic is that children have no obvious organic pathological changes, but have obvious anorexia performance in daily diet, that is, a symptom of lack of appetite for food, or even refusal to eat, which forms a clear contrast with gluttony and love for food. [0003] Indigo fruit has been reporte...
