Description
Technical field
The present invention relates to a kind of ready-mixed oil, relate more specifically to a kind of stable in properties, aliphatic acid more balances, take into account intelligence development, reduce angiocardiopathy function and the high ready-mixed oil of security.
Background technology
The World Health Organization (WHO) and FAO (Food and Agriculture Organization of the United Nation) (FAO) suggestion, in the fat of human body absorption every day, the ratio of three kinds of aliphatic acid is with saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid=1: be advisable at 1: 1.In October, 2000 publishes, " the DRIs Chinese DRIs " book write by Chinese Soclety of Nutrition, the up-to-date summary of China to the investigation and application of various diet nutritional Dietary reference intakes, done to revise to the intake of China resident to fat in this book and to composition fat main matter---the absorption ratio of various aliphatic acid has made following recommendation: the percentage that adult fat's intake accounts for gross energy is 20%-30%, wherein saturated fatty acid is less than 10%, monounsaturated fatty acids 10%, polyunsaturated fatty acid 10%, omega 6 polyunsaturated fatty acid: omega-3 polyunsaturated fatty acids=(4 ~ 6): 1.
And the first two plants fatty acid supplying fully then a kind of undersupply in the current edible oil of China, but polyunsaturated fatty acid role in human body is still important, be prostaglandin, the eicosenoic acid such as leukotriene and thromboxane that alpha-linolenic acid can generate different series if ω-6 is linoleic acid and ω-3, participate in the important biomolecule chemical processes such as immunological regulation in body, the formation of inflammatory reaction and thrombus and dissolving, important impact is produced on health.ω-6 is that linoleic acid can by extending the arachidonic acid (ARA) that in carbochain and desaturation production brain (phosphatide), content is maximum in human body, and ω-3 to be alpha-linolenic acid generate the DHA (DHA) that in brain (phosphatide) and retina, content is maximum and eicosapentaenoic acid (DPA) by extending carbochain and desaturation in human body.Described clupanodonic acid (DPA) is made up of ω-3DPA (ω-3 type clupanodonic acid) and ω-6DPA (ω-6 type clupanodonic acid).The ω such as above-mentioned ARA, EPA, DPA, DHA-6 are be long-chain polyunsaturated fatty acid with ω-3 is all the indispensable essential fatty acid of human body, is called as long-chain polyunsaturated fatty acid (LCPUFA).Although ω-6 is linoleic acid can synthesize arachidonic acid (ARA), DPA in vivo, ω-3 is that alpha-linolenic acid can synthesize EPA, DPA, DHA in vivo, but human body need use with a series of enzyme when utilizing above-mentioned two kinds of essential fatty acids synthesis other polyunsaturated fatty acid isonomic, due to competitive inhibitory effect, aggregate velocity is slow in vivo to make it, make its synthetic quantity can not meet Human Physiology needs, because the omega-3 unsaturated fatty acid half-life is short, only about 10h, can not accumulate in body, therefore needed by human directly supplements above-mentioned polyunsaturated fatty acid.
2007, Nutrition and Food Safety Office of China Disease Prevention and control Centre and beneficial Hai Jiali research and development centre form joint project group, utilize Chinese residents nutrition in 2002 and health survey non-confidential data with the fatty acid data in " Chinese food component list " database (for the food do not had in fatty acid data storehouse, carry out substituting of same group food), comprehensive deep analysis has been carried out to the dietary fat of China resident, main fatty acid Intake status, ω-6/ ω-3 ratio of Chinese residents is higher, all exceeds Chinese Soclety of Nutrition's recommended range; Omega-3 polyunsaturated fatty acids (ω-3PUFA) intake is generally on the low side; Low especially with Long carbon chain polyunsaturated fatty acid (LCPUFA) intake that DHA (DHA), eicosapentaenoic acid (EPA) are representative, mean intake is only 37.6mg/ days.Wherein in the daily aliphatic acid absorption of the Chinese residents of 25%, ω-3-LCPUFA (DHA & EPA) is 0, and Rural-urban Gap is remarkable, the DHA & EPA intake of city dweller is about 1 times of urban residents, but total amount is all not high.Compared with developed countries, it is huge that the DHA & EPA of Chinese residents compares gap, in the urgent need to carrying out supplementing of ω-3-Long carbon chain polyunsaturated fatty acid (ω-3-LCPUFA).Because Long carbon chain polyunsaturated fatty acid role in human body is still important, as promoted, the growth of brain and optic nerve, prevention cardiovascular and cerebrovascular disease (suppressing thrombus, reducing blood lipid and cholesterol), anti-inflammatory suppress allergic reaction, Tumor suppression, promotion bone growth etc.
For this reason, those skilled in the art makes Beneficial, according to the different requirements of different crowd to ARA, EPA, DPA, DHA, ARA, EPA, DPA, DHA ratio in ω-3 long-chain polyunsaturated fatty acid (ω-3LCPUFA) making it obtain meets himself needs, avoid wherein a certain deficiency or excessive, while effectively supplementing, avoid it to have side effects.Such as ARA and DHA keeps a rational ratio, for they synergies, completes normal physiological function, also has great importance.In breast milk, ARA content is at 0.5-0.7%, DHA content is at 0.3-0.5%, EPA content 0.04-0.1%, DPA content 0.17-0.26%, and the ratio of ARA and DHA is close to 2, with the ratio in newborn baby fat closely, this is the result of nature long-term evolution, also hint both balance meaning.2000, Tam etc. took mouse as research model, find that high dose takes in DHA, ARA in mouse body (arachidonic acid) will be caused to reduce.When ARA is lower than in body during normal level, as suitable supply DPA, then the DPA of supply will be reversed in animal body and turn to ARA, to compensate the reduction of ARA, make ARA be tending towards normal; If ARA is not lower than normal level, then DPA can not reverse and turn to ARA.(Lipids 2000,35:71-75.) 2006, Colin Ratledge thinks that DPA is unlike EPA (EPA can impedance human body utilize DHA), DPA can not impedance DHA to the brain tissue of infant, adult, amphiblestroid nutritive effect.(AOCS PRESS 2006:101.) in the past people focuses mostly in DHA, ARA, EPA to the research of LCPUFA contained by breast milk, also only emphasizes the benefit of supplementary DHA and ARA, compare ignorance to DPA always in baby formula milk powder grease.In fact contain a certain amount of DPA in animal body, in breast milk.2009, company of Erie disclosed China's 97,5 cities breast milk fatty acids data, found the DPA (n-6DPA:0.06-0.09% that breast milk fatty acids contains; N-3DPA:0.11-0.17%).(Lipids2009，44：257-271)
For this reason, those skilled in the art do Beneficial.
Chinese patent CN101142947A disclosed " a kind of nutrition balanced mixed oil and production method thereof containing fish oil or Fish oil " is although give DHA, EPA, DPA addition in ω-3LCPUFA, but deficiency is, do not provide reasonable amount for China's resident's dietary int ake, also do not do any research to equilibrium relation between DHA, EPA, ARA, DPA, also undeclared how taking measures makes product have good local flavor (sheltering fishlike smell) etc.
CN100521953C disclosed " a kind of nutrition balanced mixed oil containing algal oil and production method thereof " and CN101617721A disclosed " having the healthy edible blend oil balanced in nutrition of brain-invigorating " only adds algal oil, though algal oil does not only contain DHA containing EPA substantially, but the DHA nourished will reverse as EPA at human body, thus EPA in body is raised further, because EPA and ARA exists competition metabolism relation, cause ARA to reduce further again, finally lose the balance of LCPUFA.In sum, so far there are no to the report about equilibrium relation between DHA, EPA, ARA, DPA.
Therefore, no matter add fish oil or algae oil, it is necessary that fish oil+ARA+DPA or algae oil+ARA+DPA supplements as LCPUFA, and the more important thing is can effectively be supplemented by equilibrium relation while avoid having side effects.
In sum, this area lacks a kind of health blend oil of DHA, EPA, DPA, ARA equilibrium relation; Therefore, this area is in the urgent need to developing the health blend oil of a kind of DHA, EPA, DPA, ARA balance.

In above embodiment 1-7 gained ready-mixed oil, aliphatic acid composition sees the following form.
As can be seen from following table 1, in the ready-mixed oil finished product of each embodiment, various aliphatic acid accounts for TFA weight percentage and all meets following scope: saturated fatty acid 7%-17%, monounsaturated fatty acids 33-47%, omega 6 polyunsaturated fatty acid 35-45%, omega-3 polyunsaturated fatty acids 5%-9%, and total polyunsaturated fatty acid is 41-53%.
Accelerated oxidation experiment, high temperature experiment, baking oven experiment, culinary art stability experiment, frying stability experiment have all been carried out to above embodiment 1-5.Oil sample O is blank sample, and it is as follows that embodiment 1-5 oil sample is designated as P, Q, R, S, T experimental result respectively:
1. accelerated oxidation experiment
Grease oxidation rancid instrument (Rancimat) is adopted to detect the induction time of sample.The results are shown in following table 2.
Table 2
OSI value is one of important indicator of measure oil oxidation stability.As shown in Table 4, the initial oxidation degree of different oil sample is suitable, and OSI testing result, all between 23-25 hour, does not have significant difference yet, illustrates and has no significant effect the accelerated oxidation performance of ready-mixed oil.
2. high temperature experiment
High temperature experiment can reflect grease stability in the presence of a harsh environment preferably.180 DEG C of Heating Experiments continue for altogether 6 hours, and from acid value, peroxide value and color, the ready-mixed oil no matter adding fish oil+ARA+DPA or algae oil+ARA+DPA, compared with blank oil sample, does not all have notable difference.But, the destruction of high temperature to PUFA is apparent.Along with the prolongation of time, DHA & EPA & ARA & DPA content continues to reduce, in 1.5 hours, DHA & EPA & ARA & DPA loses less than 10%, and after 6 hours, the storage rate of DHA & EPA only has 71.5%, this illustrates that the oil being rich in DHA & EPA & ARA & DPA only can carry out Short Time Heating, but is not suitable for long-time high-temperature heating.
3. baking oven experiment
Baking oven experiment is one of method more accurately of Fast Evaluation grease shelf stabilities, can be predicted the shelf time of grease by baking oven experimental result.The acid value of all oil samples, peroxide value and color are all highly stable, and fluctuating range is all very little.
Because grease when baking oven is tested directly contacts with air, and environment temperature is higher, and therefore, the oxidation of grease is inevitable.But it is very little that the present inventor finds that the content of the DHA & EPA & ARA & DPA of each concentration series reduces amplitude.The situation of change of comprehensive conventional physical and chemical index and DHA & EPA, the stability of experiment oil sample is better.
4. cuisine experiment
Cuisine experiment can represent that consumer finally takes in the aliphatic acid situation in body very intuitively.The present inventor selects the reason of cooking shredded potato to be because itself lighter free from extraneous odour, can evaluate the local flavor in cooking process.In cooking process, fishlike smell or algae fishy smell is not had to produce in kitchen fume, the cooking shredded potato fried out is also without obvious fishy smell, simultaneously, the retention rate of DHA & EPA & ARA & DPA is up to 94.9%, under absolutely proving conventional culinary art condition, DHA & EPA & ARA & DPA kept stable, can not be lost in cooking process.
5. frying stability
Owing to containing more ω-3-LCPUFA (Long carbon chain polyunsaturated fatty acid) in the ready-mixed oil of interpolation fish oil+ARA+DPA or algae oil+ARA+DPA, therefore itself and be not suitable for frying, but in order to examine or check its stability, the present inventor has still carried out frying experiment.In frying experiment, food have employed chicken wings and French fries respectively, to represent animality and plant food respectively, and about 45 minutes total times of frying.At the frying process initial stage, local flavor that is blank and R (adding 1.5% fish oil) oil sample does not have notable difference, food after frying does not have fishlike smell, but in the frying later stage, after particularly frying French fries 8 times, the grease containing fish oil starts to occur light fishy smell, but the mouthfeel of French fries and local flavor are not affected, at flavor evaluation, even have people more than half to like the French fries frying out containing fish oil grease, this also demonstrates the viewpoint that plant food is suitable for animal raw fat frying.From the acid value of routine, peroxide value and color, blank with contrast oil sample all without significant difference.After frying 10 French fries and 5 chicken wings, total retention rate of DHA & EPA & ARA & DPA is respectively 83.9% and 87.5%, a little less than the retention rate (92.3% and 91.9%) of ALA under equal conditions (alpha-linolenic acid), again illustrate that the high temperature frying of short time is limited on the impact of ω-3-LCPUFA.
Flavor evaluation is tested
Respectively flavor evaluation is carried out to the ready-mixed oil finished product that embodiment 1-5 obtains, amounts to through research and development centre professional 25 people to carry out cold oil stage and deep fat cooking stage (stir-fry cooking shredded potato) flavor evaluation to the fishy smell of this ready-mixed oil finished product.
Table 3 cold oil flavor evaluation table
Table 4 deep fat cooking flavor evaluation table
As can be seen from table 3 and table 4, when DHA & EPA content is less than 408mg, substantially can't smell any fishy smell; When DHA & EPA content is more than 408mg, no matter be that all someone can snuff fishy smell for cold oil or deep fat cooking, and increase along with DHA & EPA concentration, fishy smell degree is also increasing progressively.
Above-mentioned a series of stability experiment result proves, the ready-mixed oil product stability adding fish oil (algae oil)+ARA+DPA is better, in the storage, cooking process of routine, the loss of DHA & EPA & ARA & DPA is limited; Product special flavour is better, without bad flavors such as obvious fishy smell; Feasible in the ready-mixed oil product technology of interpolation fish oil (algae oil)+ARA+DPA.
The foregoing is only preferred embodiment of the present invention, and be not used to limit substantial technological context of the present invention, substantial technological content of the present invention is broadly defined in the right of application, any technology entities that other people complete or method, if with application right define identical, also or a kind of change of equivalence, be all covered by being regarded as among this right.
The all documents mentioned in the present invention are quoted as a reference all in this application, are just quoted separately as a reference as each section of document.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read foregoing of the present invention, these equivalent form of values fall within the application's appended claims limited range equally.
