Description

The extraction and refinement method of Fructus Ligustri Lucidi fruit juice

What the present invention relates to is the extraction and refinement method of fruit juice, especially a kind of extraction and refinement method of Fructus Ligustri Lucidi fruit fruit juice.

Fructus Ligustri Lucidi really contains multiple nutrient substance to the human body beneficial, not only aminoacid is arranged, trace element, but also contain abundant triterpenoid compound, mannitol etc.Having recorded and narrated Fructus Ligustri Lucidi in Compendium of Material Medica really has invigorating middle warmer, settling five organs, foster spirit, removes all kinds of diseases and ailments, for a long time the strong not old effect of making light of one's life by commiting suicide of clothes fertilizer.At " Chinese medicine voluminous dictionary " but in also recorded and narrated the invigorating the liver and kidney of Fructus Ligustri Lucidi fruit, strong waist knee joint, controlled the deficiency of YIN, interior-heat, dizziness, order flower, tinnitus, soreness of the waist and knees, early whitening of beard and hair etc.Recent study proves: contained triterpenoid compound has heart tonifying, diuresis, protects the liver, suppresses effects such as tumor, enhancing human body immunity power in the Fructus Ligustri Lucidi fruit.The Fructus Ligustri Lucidi fruit is different with other fruit, and the little juice of Fructus Ligustri Lucidi fruit is few, contains plurality of active ingredients, and bitter taste is arranged, and color and luster changes greatly.At present, the extracting method of relevant Fructus Ligustri Lucidi fruit juice does not see that as yet report is arranged.If adopt common juice extraction method improper, the abundant extraction and application of effective ingredient in the Fructus Ligustri Lucidi fruit, and the color and luster local flavor of product and quality are all relatively poor.

The objective of the invention is characteristics, provide a kind of and can fully extract effective ingredient in the Fructus Ligustri Lucidi fruit, the extraction and refinement method of practicable Fructus Ligustri Lucidi fruit juice according to the Fructus Ligustri Lucidi fruit.The health-care effect that the Fructus Ligustri Lucidi fruit is had is able to sufficient utilization.Have good taste and outward appearance as food.

The technical solution adopted in the present invention is: adopt the grading extraction partition method to adopt and obtain through refining Fructus Ligustri Lucidi fruit juice.That is: a) with the Fructus Ligustri Lucidi dried fruits fruit collected after cleaning, smash to pieces with bruisher, place extractor, press 1000g Fructus Ligustri Lucidi dried fruits fruit and add 10000～20000ml clear water, be heated to and boil, extracted 60～120 minutes, extracting solution is leached, add 10～100ml citric acid, be concentrated into and contain solid content 10～20% o'clock, promptly obtain Fructus Ligustri Lucidi fruit juice A liquid; B) will extract after water liquid filter in the residue behind the Fructus Ligustri Lucidi fruit juice A liquid does, edible ethanol 8000～the 15000ml of adding 95%, carried out reflux, extract, 3～6 hours, after extracting solution leached, place concentrator, concentrate and reclaim ethanol, wait to be concentrated into and contain oleanolic acid 0.8～1.3% o'clock, promptly obtain Fructus Ligustri Lucidi fruit juice B liquid.

Fructus Ligustri Lucidi fruit juice A liquid that employing the present invention obtains and B liquid can be mixed with various types of Privet fruit drinks (high glycoform, middle sugared type, the beverage of low-sugar type, plain edition and high dense type (containing triterpenoid compound amount height)) after adding an amount of sweet adjuvant.Its color and luster is good, and sense of taste is coordinated soft, sour and sweet palatability, and the free from admixture abnormal flavour has good nutrition health-care functions.The needs that are fit to current domestic and international consumers in general.Can make consumer can both enjoy the characteristic natural health-care beverage that contains Fructus Ligustri Lucidi fruit juice throughout the year.The present invention changed people usually with the Fructus Ligustri Lucidi fruit only as the traditional habit of Chinese crude drug, expand out a new road for this exploitation that contains materials such as necessary trace element of tens kinds of human bodies and triterpenoid compound of Fructus Ligustri Lucidi fruit, provide possibility for Fructus Ligustri Lucidi fruit commodity enter suitability for industrialized production, had development prospect widely.

Concrete extraction and refinement method of the present invention is provided in detail by following examples.

Embodiment: the Fructus Ligustri Lucidi dried fruits fruit of collecting is taken by weighing 1000g (will go rotten in advance rotten fruit and foreign material are removed), after with clear water fruit surface being rinsed well, smash to pieces with bruisher, place extractor, behind the clear water of adding 15000ml, be heated to and boil, extracted 90 minutes, extracting solution is leached, add citric acid 20g, be concentrated into when containing solid content 15%, promptly obtain Fructus Ligustri Lucidi fruit juice A liquid; The water liquid filter that to extract then in the residue behind the A liquid is done, and adds 95% edible ethanol 10000ml, carries out reflux, extract, 3～4 hours, extracting solution is leached, place concentrator, concentrate and reclaim ethanol, wait to be concentrated into when containing oleanolic acid 1%, promptly obtain Fructus Ligustri Lucidi fruit B liquid.Contain a certain amount of tannin at the Fructus Ligustri Lucidi fruit juice A liquid that extracts, when too high, can adopt the gelatin method to remove tannin, to reduce astringent taste as if tannin content.Because the Fructus Ligustri Lucidi fruit juice A liquid obtained through refining is different with the contained material of B liquid, so when adopting the Fructus Ligustri Lucidi fruit juice synthetic beverage that the present invention obtains through refining, should suitably adjust the proportioning of Fructus Ligustri Lucidi fruit juice A liquid and B liquid according to different needs.
