Description

A kind of nutrition balanced mixed oil and production method thereof that contains algal oil
Technical field
The present invention relates to a kind of edible blend oil that contains additive, particularly a kind of nutrient blend oil and production method thereof.
Background technology
For a long time, China's edible oil and fat health care is not subjected to enough attention always, and various fatty acid compositions are rational allocation not.The intake of aliphatic acid in the relevant meals, the World Health Organization and FAO's suggestion, the aliphatic acid of human body absorption every day is saturated fatty acid (SFA) with the ratio of three kinds of aliphatic acid: monounsaturated fatty acids (MUFA): polyunsaturated fatty acid (PUFA)=1:1:1 is advisable.And the first two plants fully then a kind of undersupply of fatty acid supplying in the present edible oil of China, but polyunsaturated fatty acid role in human body still is important, as ω-6 is that linoleic acid and ω-3 are the eicosenoic acids such as prostaglandin, leukotriene and thromboxane that alpha-linolenic acid can generate different series, important biomolecule chemical processes such as the formation of immunological regulation in the participation body, inflammatory reaction and thrombus and dissolving produce significant effects to health.ω-6 is that linoleic acid also can generate the maximum arachidonic acid (AA) of content in the brain (phosphatide) by prolonging carbochain and desaturation effect in human body, and ω-3 to be alpha-linolenic acid can generate the maximum DHA (DHA) of content in brain (phosphatide) and the retina and eicosapentaenoic acid (EPA) and clupanodonic acid (DPA) by prolonging carbochain and taking off full effect in human body.ω-6 such as above-mentioned AA, EPA, DPA, DHA are and ω-3 is that long carbochain polyunsaturated fatty acid all is the indispensable essential fatty acid of human body, are called as long-chain polyunsaturated fatty acid (LCPUFA).Though being linoleic acid, ω-6 can synthesize AA (arachidonic acid) in vivo, DPA, ω-3 is that alpha-linolenic acid can synthesize EPA (acid of peanut pentaene) in vivo, DPA, DHA, but human body need use with a series of enzymes when utilizing synthetic isonomic other polyunsaturated fatty acid of above-mentioned two kinds of essential fatty acids, because competitive inhibitory effect, aggregate velocity is slow in vivo to make it, 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 the body.Therefore, it is that linoleic acid and ω-3 are alpha-linolenic acid that human body not only needs to provide the ω-6 as synthesis material, also will every day replenishes ω-3 long-chain polyunsaturated fatty acid (ω-3LCPUFA).
ω-6 is that linoleic acid can obtain from various plants oil, ω-3 is that alpha-linolenic acid can obtain from linseed oil, soybean oil, Canola Oil, Purple Perilla Seed Oil, content is seldom in edible oil for the oil of above-mentioned kind in the prior art, therefore oil with common edible supply ω-3 is the aliphatic acid deficiency, especially lack ω-3 long-chain polyunsaturated fatty acid (ω-3LCPUFA), people can only replenish by edible all kinds of health products, as edible deep-sea fish oil soft capsules, seal oil soft capsule, little algae fat capsule etc.But consumers in general lack relevant nutrition professional knowledge, can not correctly replenish, and forget easily and take, supply that can not continuous and effective, so both strengthened people's life cost, be difficult to again obtain the balanced nutrients composition, do not reach wholesome purpose, how correctly to replenish is a difficult problem of exploring.(ω-3LCPUFA) is an approach that economically feasible is convenient and practical to replenish ω-3 long-chain polyunsaturated fatty acid in the human body by edible oil.
To correctly replenish grease, should reach following requirement: 1, the aliphatic acid of taking in every day is saturated fatty acid (SFA) with the ratio of three kinds of aliphatic acid: monounsaturated fatty acids (MUFA): polyunsaturated fatty acid (PUFA)=1:1:1, linoleic acid is that 4~6:1 is advisable with the ratio of the content of alpha-linolenic acid, mainly is that the ω-6 as synthesis material is that linoleic acid and ω-3 are that the alpha-linolenic acid supply should be abundant.2, ω-3 long-chain polyunsaturated fatty acid (ω-3LCPUFA) except that synthetic in human body, also need directly replenish every day.3, according to the different needs amount of different crowd to DHA, DPA, EPA, (DHA, DPA, EPA ratio among the 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, when effectively replenishing, avoid it to have side effects.For this reason, those skilled in the art has done useful trial.Chinese patent CN1483336A disclosed " balanced nutrients ready-mixed oil ", it has stipulated that the ratio of the content of monounsaturated fatty acids (MUFA) and polyunsaturated fatty acid (PUFA) is 1:1, linoleic acid is 4~6:1 with the ratio of the content of alpha-linolenic acid, but do not consider the ratio of saturated fatty acid, directly do not add ω-3 long-chain polyunsaturated fatty acid (ω-3LCPUFA) yet; Chinese patent CN1448061A discloses the production method of golden imperial fish second generation nutrient blend oil, though it has considered saturated fatty acid (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acid (PUFA) ratio, considered that also ω-6 is that aliphatic acid linoleic acid and ω-3 are the content ratio of aliphatic acid alpha-linolenic acid, but there is following defective in it: 1, directly do not add the how unsaturated essential fatty acid of ω-3 long-chain (ω-3LCPUFA), (ω-3LCPUFA) is that leukotrienes transforms in human body and gets by ω-3 only to the ω of needed by human body-3 long-chain polyunsaturated fatty acid, can not satisfy the human body needs.2, the grease of heterogeneity and proportioning is not provided at the crowd demand of all ages and classes stage and health status.In order to replenish ω-3 is aliphatic acid, and its technical scheme that adopts is the proportion that increases rapeseed oil, and its shared percentage by weight reaches 20~65%, is its Main Ingredients and Appearance, is the purpose of aliphatic acid though this patent has realized additional ω-3, because of rapeseed oil contains erucic acid, promptly along Δ 1322 carbon monoenoic acids, it is a kind of long-chain monounsaturated fatty acids, its carbochain is than the sour four carbon atom that manys of common fats.Erucic acid has no adverse effects for the normal human of health, contains a kind of enzyme that digests erucic acid that decomposes in the human body, and it can destroy the erucic acid of picked-up, is absorbed by the body to enter blood after digestion.Under the cardiovascular function normal condition, it can not cause in the human body the especially fat accumulation of cardiovascular system of some organ, brings out pathology.But for the cardiac, but there is the possibility that causes " myocardium fat deposition ", show according to investigations, the phenomenon of " the myocardium fat deposition " that causes owing to edible rapeseed oil accounts for whole cardiac's 4/5, the U.S. once found from 100 routine cardiac's corpse of dissecting, the erucic acid that truly has in " cardiac muscle fat " exists, and content reaches more than 5.6%.Because accept on a small quantity by behind the erucic acid after the enzymic digestion every day in cardiac's the blood, abnormal cardiovascular function will excess load originally, and easier bringing out " vessel wall thickening " reaches " myocardium fat deposition ", directly endangers healthy.Therefore, it is edible that the ratio of the imperial fish second generation nutrient blend oil of gold is not suitable for the cardiovascular and cerebrovascular patient, improving ω-3 by the ratio that increases rapeseed oil is that content of fatty acid does not have general applicability, does not have the consumer under the prerequisite of relevant nutrient knowledge and can cause adverse effect to the cardiovascular and cerebrovascular diseases people.3, key component in this oil---soybean oil and rapeseed oil are the transgenosis grease.Whether GM food especially exists potential hazard not prove through long-term practice to fetus, baby, child, children and adolescent growth growth to human body.
Chinese patent application CN1398532A disclosed " a kind of preparation method of functional olive oil concentrating agent ", Chinese patent application CN1398533A disclosed " a kind of functional high-grade cooking olive oil and preparation method thereof ", Chinese patent application CN1191677A " a kind of functional natural edible oil " is though added deep sea fish oil in the prescription, but there is following problem in above-mentioned patent application: 1, do not consider fatty acid total amount and form the requirement whether meet the human nutrition equilibrium that the aliphatic acid of taking in every day with human body is not saturated fatty acid (SFA) with the ratio of three kinds of aliphatic acid: monounsaturated fatty acids (MUFA): polyunsaturated fatty acid (PUFA)=1:1:1 is that prerequisite is added deep sea fish oil; 2, do not mention and do not set forth main active DHA in the deep sea fish oil, EPA physiology and health-care effect yet, more do not analyze the content of DHA and EPA in the deep sea fish oil, must cause that to replenish the indeterminate and additional dosage of purpose inaccurate.In actual applications, because manufacturer is different with specification, (ω-3LCPUFA) DHA is also different with content and the proportioning thereof of EPA for ω in the fish oil-3 long-chain polyunsaturated fatty acid, DHA and the EPA content according to accurate Calculation does not add deep sea fish oil, must cause magnitude of recruitment inaccurate, phenomenon on the low side or higher occur; The physiological requirements of not satisfying human body on the low side, excessive absorption then can be because of the unsaturated double-bond generation peroxidization in its structure, produce lipid peroxide, this is a kind of free radical, be one of hazards that promote old and feeble and generation cancer, body is produced multiple chronic hazard, if come across skin, then form lipofuscin and senile plaque expelling occurs as this lipid peroxide; If come across in the cell, cell function is weakened; The unrighted acid of adiposis patient Excessive Intake easily causes cholelithiasis; Studies have shown that the rising of lipid peroxide is bigger to the harm that atherosclerotic forms than the rising of cholesterol in the blood.3, DHA that is added and EPA weight ratio science not can not satisfy the physiological requirements of different edible objects.EPA can be metabolized to prostacyclin in human body, and then the body sexual function, as the excessive EPA of children taking, the possibility that promotes sex premature is arranged, the inhibition that EPA also has children's intelligence and skeleton development.DHA is easy to enter brain cell by the brain barrier, is present in brain cell and the brain cell projection, and children's excessive use will cause nerve to be overexcited.Therefore, DHA and EPA content proportioning be science not, also can cause the influence healthy to some crowd.Though 4, above-mentioned three kinds of prescription edible oils have added and contain ω-3 long-chain polyunsaturated fatty acid (deep sea fish oil of ω-3LCPUFA) adds heat stabilization test, can keep how many compositions also for unknown after culinary art heating process.
Therefore, the suitable grease of screening from each vegetable oil, add the rational additive of collocation, replenish (the ω-3LCPUFA) of ω-3 long-chain polyunsaturated fatty acid in the human body by edible oil, the nutrient blend oil of different cultivars is provided for different crowd, being an approach that economically feasible is convenient and practical, is again the difficult problem that needs are further explored.
Marine alga, promptly little algae is that a class contains chlorophyllous vegetalitas aquatic microorganisms usually, and for example spirulina is the protobiont of DHA, DPA, EPA, and fish then is the aggregation of mentioned component.From marine algae, separate and be rich in DHA+DPA+EPA; or only contain DHA+DPA; or only contain DHA, do not contain or contain hardly the marine alga algae kind of EPA, do not contain pollutant, edible nutrient solution and carry out scale and cultivate by adding, thereby can produce a large amount of marine algas.With these marine algas is raw material, adopts methods such as supercritical carbon dioxide extracting, can obtain containing the vegetable fat of nutritional labelings such as lipid such as DHA and effective active growth factor.Especially can obtain with relatively low cost being rich in DHA+DPA+EPA, or only contain DHA+DPA, or only contain different types of algal oils such as DHA.Accomplish scale production at present, make the extensive use of algal oil possess economic feasibility.
Because the health-care efficacy of algal oil, it has been made into various forms of health products and has sold on market.But algal oil is joined in the edible oil, make edible oil have health care, yet there are no the report of correlative study at home and abroad, also do not see suitability for industrialized production.

Beneficial effect of the present invention is:
The present invention replenishes ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA) DHA, EPA, DPA by edible oil and fat, avoids other health products to forget and takes phenomenon, and reinforcing method is science more.The purpose that the present invention selects for use algal oil to realize replenishing ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA) as additive has the following advantages:
1, algal oil contained ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA) has comprised DHA, EPA, DPA, and its effect is respectively:
EPA: be commonly called as " blood vessel street cleaner ", can make certain prostaglandin, this prostaglandin can make angiomalacia and suppress blood platelet and condense in blood vessel, has the vascular sclerosis of preventing, cardiovascular and cerebrovascular embolism, reduces effects such as hypertension, high fat of blood and cholesterol.Be applicable to coronary sclerosis and thrombus, headstroke, cerebral hemorrhage, cerebrovascular disorder, high cholesterol, high fat of blood, hypertension, hand and foot numbness, various cardiovascular and cerebrovascular diseases such as palpitaition.
DHA: be commonly called as " brain gold ", content in optic cell and retinal tissue is up to 40~47%, be aliphatic acid important in brain, nerve, the cellula visualis, have the memory of enhancing and the power to think, improve intelligence, regulate and improve eyesight, reduce the incidence of women's neurasthenia in postpartum and depression, prevention and treatment senile dementia, prevention dry skin and aging, acceleration skeleton increases, preventing effects such as osteoporosis, is that brain tissue and optic nerve are grown and function is brought into play necessary nutriment.
DPA: content height in human milk is that fish oil and other food lack.DPA is for the softness that keeps the arterial blood tube wall, and the flexible effect that promotes vascular wall and EPA are as similar, and Japanese scholar's research thinks that the interior EPA of body only changes into DPA and just can play a role, and DPA exceeds 10~20 times than EPA effect.DPA can promote and improve the immunity of human body, can enter the phospholipid layer of epicyte rapidly, has the special physical action of the cell membrane of reinforcement, promote function of plasma membrane, resist wreaking havoc of free radical, to diabetes, rheumatoid arthritis, psoriasis, asthma, ulcer colo-enteritis etc. all has therapeutic action.The pregnant woman replenishes enough DPA at the initial stage of pregnancy, helps to be pregnant with the sound fetus of the circulatory systems such as heart, blood vessel; DPA is the same with DHA to be formed for people's composition of milk, and part expert thinks that DPA may play an incognizant more important role in the past.
2, marine alga is the protobiont of DHA, DPA, EPA, is to cultivate by the scale of purebred marine alga to obtain, and can produce algal oil with relatively low cost.Different marine alga algae kinds can be produced the algal oil of heterogeneity, can satisfy the needs of different crowd.DHA good stability in the algal oil, has unique marine alga flavor, no fishlike smell, for its extensive use has possessed economic feasibility, especially by separating the purebred algal oil of producing of little algae of the EPA that does not contain or only contain trace, be not subjected to marine pollution, be clean most, safest vegetalitas DHA, be adapted to most to be added in cleaning and safety requirements very high pregnant woman, newborn woman, baby, child and the infant foods.
3, algal oil does not contain cholesterol, avoids causing body's cholesterol higher.As everyone knows, unnecessary LDL-C LDL-C can pierce the arteries endothelium, forms patch, and artery-clogging causes coronary heart disease, cerebral infarction, perhaps causes serious consequences such as myocardial infarction, sudden death along with plaque rupture.
The present invention has compiled the fatty acid proportion of Various Edible fat, see Table 1, moving according to difference, various fatty acid proportions in the vegetable fat, the absorption ratio of various aliphatic acid in China resident's that " DRIs " book of writing with reference to Chinese Soclety of Nutrition is recommended the diet nutritional intake, as shown in table 2, saturated fatty acid (SFA) to different crowd, monounsaturated fatty acids (MUFA), ω-6 is that polyunsaturated fatty acid (ω-6 PUFA) and ω-3 are that polyunsaturated fatty acid (ω-3 PUFA) requirement is calculated, draw Chinese residents meals grease intake, as shown in table 3.Concrete computational process is: become the human fatty acid intake to account for 20~30% saturated fatty acids (SFA) of gross energy: monounsaturated fatty acids (MUFA): polyunsaturated fatty acid (PUFA)=1:1:1 ratio, ω in the polyunsaturated fatty acid-6 are that polyunsaturated fatty acid (ω-6 PUFA) and ω-3 are that polyunsaturated fatty acid (ω-3 PUFA) ratio is 4~6:1; Eating habit according to China resident, animal food can be brought fractional saturation aliphatic acid into, should deduct animal food in the finished product ready-mixed oil and can bring fractional saturation aliphatic acid into, so its saturated fatty acid (SFA): monounsaturated fatty acids (MUFA): the appropriate ratio of polyunsaturated fatty acid (PUFA) should be 0.35:1:1.One day fatty intake=(0.30 * RNI)/36700 of resident, 0.3 should account for the ratio of food intake gross energy for fat, RNI is the energy intake of the Chinese residents meals recommended of Chinese Soclety of Nutrition's " DRIs " of writing, 36700 is the energy that every gram fat produces in the food (J of unit, its value is more lower slightly than the energy 39700J that every gram fat in the body produces).As adult man of 18~49 years old age, be engaged in middle physical exertion, one day fatty intake=0.3 * 11.30 * 1000000 ÷ 36700=92.4g then, calculate its saturated fatty acid (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acid (PUFA) intake thus and be 30.8g (pressing 1:1:1 calculates), ω-6 is that intake is 24.64~26.4g in the polyunsaturated fatty acid (PUFA), and ω-3 is that intake is 6.2~4.4g (calculating by 4~26:1).Because of the basic balance of aliphatic acid that provides in the loss aliphatic acid in the cooking process and other food, so every day, the edible oil and fat demand still was 92.4g.As known from Table 3, the crowd of all ages and classes, sex, labour intensity fat requirement difference, fatty requirement is up to wet nurse, and every day, the fat requirement was 109.4g, and fatty requirement is minimum be child (young girl) over 1 years old, and every day, fatty requirement was 36.0g.
