Description
Technical field
The present invention relates to applied chemistry technical field, particularly relate to a kind of diglyceride fluid composition rich in Cymbidium ensifolium (L.) Sw. acid and its preparation method and application.
Background technology
Diglyceride (Diacylglycerol) is the structured lipid that in a quasi-glycerol three-ester (Triacylglycerol), a fatty acid is optionally substituted by a hydroxyl group, it is micro constitutent and the endogenous centre of body fat metabolism of natural plant grease, it has two kinds of natural isomerss, i.e. 1,2-diglyceride and 1,3-diglyceride, as shown in Equation 1.
Formula 1 diglyceride structural representation (wherein COR, COR ' be saturated or unsaturated fatty acyl group)
7 kinds of article such as at present, finding through multinomial safety evaluation, diglyceride is harmless to human non-toxic, is regarded as " It is generally accepted safety " material by U.S. FDA, No. 18 bulletin approval triglyceride oil of ministry of Health of China in 2009 are new resource food.Although diglyceride and triglyceride can be worth and on absorbance essentially identical, but there is larger difference in they metabolism in vivo, short-term and long-term animal and human trial show, compared with the triglyceride formed containing same or similar fatty acid, 1,3-DAG has control and treats high blood triglyceride disease, obesity and the effect of complication thereof.Therefore, the edible oil rich in 1,3-DAG is possible not only to the oil for health care substituting triglyceride edible oil as healthy population, it is also possible to for obese people and the nutrition treatment of related complication crowd.
At present, the preparation method of diglyceride mainly has following several: (1) triglyceride alcoholysis method: i.e. under the catalysis of lipase, triglyceride reacts with lower alcohol, generate diglyceride and low-carbon-ester, but lipase the Novozyme 435 and Lipozyme IM that the method uses can only specific cleavage or synthesis sn-1 position or the ester bond of sn-3 position, therefore can only obtain 1,2-diglyceride.(2) partial hydrolysis, esterification process: i.e. first partial hydrolysis triglyceride obtains fatty acid, add glycerol, under the catalysis of sn-1 and sn-3 position selected fat enzyme, the fatty acid generation esterification that glycerol and partial hydrolysis obtain generates 1, 3-diglyceride, current most diglyceride includes that the EnovaTM Oil that KAO. Corp. SA produces develops based on this principle, the shortcoming of the method maximum is that technological process is complicated, multistep is needed to separate, in addition the utilization rate of raw material is low, additionally need use lipase, and lipase price is higher, there is the problems such as high cost for industrial scale produces diglyceride.(3) glycerol solution: will triglyceride oil and glycerol and a kind of mix containing monocarboxylic acid or the alkali metal salt of dicarboxylic acids or alkali salt or its mixture (making catalyst), by the glycerolysis of triglyceride, prepare business, food stage 1,3-triglyceride oil, but conventional glycerol rhizolomy needs to react under the high temperature of 220～260 DEG C so that the Oxidation of triglyceride, diglyceride and fatty acid particularly unsaturated fatty acid strengthens.At present, prepare triglyceride oil to be mainly by triglyceride type oil and fat preparations such as soybean oil, Oleum Brassicae campestris, Oleum Arachidis hypogaeae semen and Semen Maydis oil, prepare diglyceride with fish oil etc. for raw material and the most also have a small amount of report, as (2010) such as Feltes prepare the diglyceride rich in n-3 PUFA with lipase Novozyme 435 by triglyceride alcoholysis method；Eoma etc. (2010) synthesize the diglyceride rich in n-3 PUFA with lipase RMIM and Novozyme 435 by hydrolysis, esterification process.
Conjugated fatty acid is to polyunsaturated fatty acid position and the common name of stereoisomer with conjugate double bond system, if there being a methyl between two double bonds, we can be referred to as the double bond that methyl separates, if there being multiple methyl, we term it the double bond that many methyl separate, if two double bond conjugated are together, we term it conjugated fatty acid.Conjugated fatty acid can be with the form being diene, triolefin or tetraene, the most common conjugated fatty acid is octadecadienoic acid and jeceric acid, namely conjugated linoleic acid (Conjugated linoleic acid, and conjugate linolenic acid (Conjugated linolenic acid, CLNA) CLA).Conjugate linolenic acid is different with configuration and have multiple isomer due to position of double bond, cis8, trans10, cis12-conjugate linolenic acid (cis8, trans10, cis12-18:3, Jacaric acid) it is 8,10,12 double bond conjugation, 8 and 12 double bonds are configured as cis, and 10 double bonds are configured as trans conjugate linolenic acid (cis8, trans10, cis12-CLNA), domestic also cis8, trans10, cis12-conjugate linolenic acid is referred to as Cymbidium ensifolium (L.) Sw. acid.Cymbidium ensifolium (L.) Sw. acid can be spent the most isolated and purified the principal columns of a hall (Jacaranda minosifolia) seed from plant indigo plant and obtain, Cymbidium ensifolium (L.) Sw. acid and trans10, cis12-CLA (10,12 double bond conjugation, 12 double bonds are configured as cis, 10 double bonds are configured as trans, the most important a kind of isomer of conjugated linoleic acid) similarity be that their fatty acid chain the 10th and the 12nd is all undersaturated double bond, and spatial configuration is identical.Cymbidium ensifolium (L.) Sw. acid can be converted to trans10, cis12-CLA in animal and human body, therefore can be as trans10, natural diets source (Tsuzuki etc., 2006) important for cis12-CLA.
Conjugated fatty acid has the special physiological function different from conventional polyunsaturated fatty acid.It is reported, CLA has the most favourable physiological function, as improved humans and animals blood fat, atherosclerosis, obesity, anticancer and antihypertensive effect (Rainer etc., 2004).CLA is in the whole world, and particularly American-European countries is used widely as the functional food such as fat-reducing, blood fat reducing and health product, and it is the main isomer that CLA plays effect of weight reducing that research has proven to trans10, cis12-CLA.CLA is primarily present in milk lipid, cheese and ruminant meat.But, CLA content in these foods only has about 1% (Sehat etc., 1998), and this makes it can not make the sanatory food containing CLA or medicine with the CLA that natural resources exists.The CLA of commercial is that this isomerization product generally comprises equimolar cis9, trans11-CLA and trans10, cis12-CLA (Pariza etc., 2001) and other isomers by the oily isomerization rich in oleic acid is obtained.There is the consideration of the aspects such as safety to the CLA of preparation of industrialization in consumer, CLA industrialized production Costco Wholesale is higher, and the CLA of preparation of industrialization has various isomeric forms, and is not that every kind of isomer all has the function useful to human body.
Cymbidium ensifolium (L.) Sw. acid and the important difference of trans10, cis12-CLA are the 3rd undersaturated double bond of Cymbidium ensifolium (L.) Sw. acid, and Cymbidium ensifolium (L.) Sw. acid has a cis double bond, so Cymbidium ensifolium (L.) Sw. acid has again the feature of " polyunsaturated fatty acid " the 8th of fatty acid chain.Polyunsaturated fatty acid has important nutritive value, and triglyceride and cholesterol in humans and animals body are had useful effect, can reduce the danger of cardiovascular and cerebrovascular disease, promotes g and D.At present, polyunsaturated fatty acid is widely used in the development adding growth promoter and the intelligence promoting baby in baby food to.Research finds that Cymbidium ensifolium (L.) Sw. acid has anticancer, the metabolic syndromes such as prevention and treatment obesity, improve the function such as immunity, as United States Patent (USP) (US 2008/0045594A1) utilize Cymbidium ensifolium (L.) Sw. acid equiconjugate linolenic acid enhancing human body immunity function and treatment and with prevention of inflammation and inflammation associated metabolic syndrome such as inflammatory bowel etc..
