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 balance, take into account intelligence development, reduce angiocardiopathy function and safe ready-mixed oil.
Background technology
In the fat that the suggestion of the World Health Organization (WHO) and FAO (Food and Agriculture Organization of the United Nation) (FAO), human body are taken in every day, the ratio of three kinds of aliphatic acid is with saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid=be advisable at 1: 1: 1.publish in October, 2000, " DRIs Chinese DRIs " book of being write by Chinese Soclety of Nutrition, be China to various diet nutritionals with reference to the research of intake and the up-to-date summary of application, in this book, China resident has been done to revise to the intake of fat and to form fat main matter---the absorption ratio of various aliphatic acid has been made following recommendation: the percentage that adult's fat 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 in the present edible oil of China, the first two plants fully then a kind of undersupply of fatty acid supplying, but polyunsaturated fatty acid role in human body is still important, be that linoleic acid and ω-3 are the eicosenoic acids such as prostaglandin, leukotriene and thromboxane that alpha-linolenic acid can generate different series as ω-6, the important biomolecule chemical processes such as the formation of immunological regulation in the participation body, inflammatory reaction and thrombus and dissolving produce important impact to health.ω-6 are that linoleic acid can be produced the maximum arachidonic acid (ARA) of content in brain (phosphatide) by extending carbochain and desaturation in human body, and ω-3 are that alpha-linolenic acid can pass through the prolongation carbochain in human body and desaturation generates the maximum DHA (DHA) of content in brain (phosphatide) and retina and eicosapentaenoic acid (DPA).Described clupanodonic acid (DPA) is comprised of ω-3DPA (ω-3 type clupanodonic acid) and ω-6DPA (ω-6 type clupanodonic acid).ω-6 such as above-mentioned ARA, EPA, DPA, DHA are and ω-3 are that long-chain polyunsaturated fatty acid is all the indispensable essential fatty acid of human body, are called as long-chain polyunsaturated fatty acid (LCPUFA).Although being linoleic acid, ω-6 can synthesize in vivo arachidonic acid (ARA), DPA, ω-3 are that alpha-linolenic acid can synthesize EPA, DPA, DHA in vivo, but human body need use with a series of enzyme when utilizing synthetic isonomic other polyunsaturated fatty acid of above-mentioned two kinds of essential fatty acids, due to competitive inhibitory effect, aggregate velocity is slow in vivo to make it, make its synthetic quantity can not satisfy the Human Physiology needs, because the omega-3 unsaturated fatty acid half-life is short, only about 10h, can not accumulate the essential directly additional above-mentioned polyunsaturated fatty acid of old friend's body in body.
2007, Nutrition and Food Safety Office of China Disease Prevention and control Centre and beneficial Hai Jiali research and development centre form the joint project group, utilize aliphatic acid data in Chinese residents nutrition in 2002 and health survey non-confidential data and " Chinese composition table of foods " database (for the food that does not have in the aliphatic acid database, carry out substituting with group food), dietary fat, main fatty acid Intake status to China resident have carried out comprehensive deep analysis, the ω of Chinese residents-6/ ω-3 ratio is higher, all exceeds Chinese Soclety of Nutrition's recommended range; (ω-3PUFA) intake is generally on the low side for omega-3 polyunsaturated fatty acids; Low especially take DHA (DHA), eicosapentaenoic acid (EPA) as long carbochain polyunsaturated fatty acid (LCPUFA) intake of representative, mean intake is only 37.6mg/ days.ω-3-LCPUFA (DHA﹠amp during wherein the daily aliphatic acid of 25% Chinese residents is taken in; EPA) be 0, and Rural-urban Gap is remarkable, city dweller's DHA﹠amp; The EPA intake is 1 times of left and right of urban residents, but total amount is all not high.Compared with developed countries, the DHA﹠amp of Chinese residents; It is huge that EPA compares gap, and (ω-3-LCPUFA) replenishes in the urgent need to carrying out the long carbochain polyunsaturated fatty acid of ω-3-.Because long carbochain polyunsaturated fatty acid role in human body is still important, suppresses allergic reaction, suppress tumour, promote bone growth etc. as growth, prevention cardiovascular and cerebrovascular disease (suppressing thrombus, reducing blood lipid and cholesterol), the anti-inflammatory that promotes brain and optic nerve.
For this reason, those skilled in the art has made Beneficial, according to the different requirements of different crowd to ARA, EPA, DPA, DHA, (ARA, EPA, DPA, DHA ratio in ω-3LCPUFA) meet himself needs to make ω-3 long-chain polyunsaturated fatty acid of its acquisition, avoid wherein a certain not enough or excessive, avoid it to have side effects when effectively replenishing.Such as ARA and rational ratio of DHA maintenance, for they synergies, complete normal physiological function, also have 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 near 2, very approaching with the ratio in newborn baby fat, this is the result of nature long-term evolution, also hints both meanings of balance.2000, Tam etc. found high dose absorption DHA take mouse as research model, will cause ARA (arachidonic acid) reduction in mouse body.When ARA lower than body in during normal level, as suitable supply DPA, the DPA of supply will be reversed in animal body and turn to ARA, the reduction with compensation ARA makes ARA be tending towards normal; If ARA is not lower than normal level, DPA can not reverse and turn to ARA.(Lipids 2000, and 35:71-75.) 2006, Colin Ratledge thought DPA unlike EPA (EPA can impedance human body utilize DHA), DPA can impedance DHA to infant, adult's brain tissue, amphiblestroid nutritive effect.(AOCS PRESS 2006:101.) people in the past focuses mostly in DHA, ARA, EPA to the research of the contained LCPUFA of breast milk, also only emphasizes to replenish the benefit of DHA and ARA in the baby formula milk powder grease, and DPA is relatively ignored always.In fact in animal body, contain a certain amount of DPA in breast milk.2009, company of Erie announced 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 have done Beneficial.
Chinese patent CN101142947A disclosed " a kind of nutrition balanced mixed oil and production method thereof that contains fish oil or Fish oil " is although provided DHA in ω-3LCPUFA, EPA, DPA addition, but deficiency is, do not take in for China resident meals and provide reasonable amount, equilibrium relation between DHA, EPA, ARA, DPA is not done any research yet, undeclaredly how to take measures to make product that local flavor (sheltering fishlike smell) etc. is preferably arranged yet.
CN100521953C disclosed " a kind of nutrition balanced mixed oil and production method thereof that contains algal oil " and CN101617721A disclosed " healthy edible blend oil balanced in nutrition with brain-invigorating " only add algal oil, though algal oil does not substantially contain EPA and only contains DHA, but the DHA that nourishes will reverse at human body and be EPA, in body, EPA further raises thereby make, due to EPA and ARA existence competition metabolism relation, cause ARA further to reduce again, finally lose the balance of LCPUFA.In sum, so far there are no to the report of equilibrium relation between relevant 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 replenish as LCPUFA, and the more important thing is when can effectively replenish by equilibrium relation and avoid having side effects.
In sum, this area lacks the health blend oil of a kind 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, the aliphatic acid composition sees the following form.
Can find out from following table 1, in the ready-mixed oil finished product of each embodiment, various aliphatic acid account for the TFA weight percentage and all meet 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%.
Above embodiment 1-5 accelerated oxidation experiment, high temperature experiment, baking oven experiment, culinary art stability experiment, frying stability experiment have all been carried out.Oil sample O is the blank sample, and embodiment 1-5 oil sample is designated as respectively P, Q, R, S, the T experimental result is as follows:
1. accelerated oxidation experiment
Adopt the induction time of grease oxidation rancid instrument (Rancimat) test sample.The results are shown in following table 2.
Table 2
The OSI value is one of important indicator of measure oil oxidation stability.As shown in Table 4, the initial oxidation degree of different oil samples is suitable, and the OSI testing result all between 23-25 hour, does not have significant difference yet, illustrates that the accelerated oxidation performance to ready-mixed oil has no significant effect.
2. high temperature experiment
The high temperature experiment can reflect the stability of grease under adverse circumstances preferably.180 ℃ of Heating Experiments have continued altogether 6 hours, from acid value, peroxide value and color, compare with blank oil sample no matter add the ready-mixed oil of fish oil+ARA+DPA or algae oil+ARA+DPA, all there is no notable difference.But, high temperature is apparent to the destruction of PUFA.Along with the prolongation of time, DHA﹠amp; EPA﹠amp; ARA﹠amp; DPA content continues to reduce, in 1.5 hours, and DHA﹠amp; EPA﹠amp; ARA﹠amp; DPA loses less than 10%, and after 6 hours, DHA﹠amp; The storage rate of EPA only has 71.5%, and DHA﹠amp is rich in this explanation; EPA﹠amp; ARA﹠amp; The oil of DPA only can carry out Short Time Heating, but is not suitable for long-time high-temperature heating.
3. baking oven experiment
The baking oven experiment is one of method more accurately of Fast Evaluation grease shelf stabilities, can predict the shelf time of grease by the 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.
When testing due to baking oven, grease directly contacts with air, and environment temperature is higher, and therefore, the oxidation of grease is inevitable.But the inventor finds the DHA﹠amp of each concentration series; EPA﹠amp; ARA﹠amp; It is very little that the content of DPA reduces amplitude.Comprehensive conventional physical and chemical index and DHA﹠amp; The situation of change of EPA, the stability of experiment oil sample better.
4. cuisine experiment
Cuisine experiment can represent the final aliphatic acid situation of taking in body of consumer very intuitively.It is because of itself lighter free from extraneous odour that the inventor selects the reason of cooking shredded potato, can estimate the local flavor in cooking process.In the cooking process, do not have fishlike smell or algae fishy smell to produce in kitchen fume, the cooking shredded potato of frying out is also without obvious fishy smell, simultaneously, DHA﹠amp; EPA﹠amp; ARA﹠amp; The retention rate of DPA proves absolutely under conventional culinary art condition DHA﹠amp up to 94.9%; EPA﹠amp; ARA﹠amp; The DPA kept stable can not be lost in cooking process.
5. frying stability
Owing to containing more ω-3-LCPUFA (long carbochain polyunsaturated fatty acid) in the ready-mixed oil that adds 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 inventor has still carried out the frying experiment.In the frying experiment, food has adopted respectively chicken wings and French fries, to represent respectively animality and plant food, approximately 45 minutes total time of frying.At the frying process initial stage, the local flavor of 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 that contains fish oil begins to occur light fishy smell, but mouthfeel and not impact of local flavor on French fries, at flavor evaluation, even there is people more than half to like containing the French fries that the fish oil grease is fried out, this has verified that also plant food is suitable for the viewpoint of animal raw fat frying.From acid value, peroxide value and the color of routine, blank and contrast oil sample are all without significant difference.After frying 10 French fries and 5 chicken wings, DHA﹠amp; EPA﹠amp; ARA﹠amp; Total retention rate of 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), illustrates that again the high temperature frying of short time is limited on the impact of ω-3-LCPUFA.
The flavor evaluation experiment
The ready-mixed oil finished product that embodiment 1-5 is obtained carries out respectively flavor evaluation, amounts to 25 people through the professional of research and development centre and the fishy smell of this ready-mixed oil finished product is carried out the flavor evaluation in cold oil stage and deep fat cooking stage (stir-fry cooking shredded potato).
Table 3 cold oil flavor evaluation table
Table 4 deep fat cooking flavor evaluation table
Can find out from table 3 and table 4, work as DHA﹠amp; EPA content can't smell any fishy smell during less than 408mg substantially; Work as DHA﹠amp; When EPA content surpasses 408mg, and though be cold oil or deep fat cooking all someone can snuff fishy smell, and along with DHA﹠amp; EPA concentration increases, and the fishy smell degree is also increasing progressively.
Above-mentioned a series of stability experiment result proves, the ready-mixed oil product stability that adds fish oil (algae oil)+ARA+DPA is better, in the storage of routine, cooking process, and DHA﹠amp; EPA﹠amp; ARA﹠amp; The loss of DPA is limited; Product special flavour is better, without bad flavors such as obvious fishy smell; Feasible on the ready-mixed oil product technology of interpolation fish oil (algae oil)+ARA+DPA.
The above is only preferred embodiment of the present invention, be not to limit essence technology contents scope of the present invention, essence technology contents of the present invention is broadly to be defined in the claim scope of application, any technology entity or method that other people complete, if defined identical with the claim scope of application, also or a kind of change of equivalence, all will be regarded as being covered by among this claim scope.
