Grease and carbohydrate, protein are listed as three large basic nutrition compositions of needed by human, have critical role in people's life and economic development.Grease not only have store with release energy, provide essential fatty acid, as the housing construction composition and have peculiar mouthfeel and improve the unique effect of food quality, and can also play the effect of saving and promoting other Nutrients Absorption, the supply of fat-soluble A, vitamin D, vitamin E, vitamin K and absorption need grease as source and medium.From chemical terms, natural oil is comprised of triglyceride saturated and that degree of unsaturation is different more than 95%, and with a small amount of miscellaneous lipid material.
Triglyceride is called for short triglycerides.It is to be formed by three fatty acid molecules and a glycerol molecule condensation.Aliphatic acid accounts for about 95% of whole triglycerides molecular weight, because aliphatic acid proportion in the triglycerides molecule is very large, so they play a leading role on the impact of the physicochemical properties of triglycerides.Say in a sense, the characteristic of grease is determined by the functional fatty acid with specific physiologically active.Will pay close attention to the nutrition of fat and aliphatic acid with the nutrition of paying close attention to edible oil.The kind of aliphatic acid is a lot, and the content of its aliphatic acid of vegetable oil of different cultivars is different, so just determined that also its nutritive value of vegetable oil of different cultivars is different.The physico-chemical property of triglycerides and function depend primarily on kind and the distribution of the fatty acid mixed that forms it, in the natural oil there are more than 800 kinds the aliphatic acid kind.In the plant grease, more with oleic acid and linoleic acid content, be palmitic acid, a-leukotrienes, laurate, stearic acid, myristic acid etc. secondly, kind and the content difference of different types of its aliphatic acid of plant resources are larger.In the terraria take palmitic acid, oleic acid and stearic acid as main; In the marine products fish oil mainly take the polyunsaturated fatty acid of growing carbochain as main.
The functional components that is present in the grease mainly comprises functional unrighted acid, phytosterol, fat-soluble vitamin such as VE, VA etc.Functional fatty acid is to refer in particular to those to derive from the human diet grease, be human nutrition and healthy essential, and some corresponding deficiency diseases of human body and the bright disease of endogenous disease, particularly advanced society such as hypertension, heart disease, cancer, diabetes etc. there is one group of aliphatic acid of positive preventive and therapeutic effect.
The composition of oil fatty acid and classification:
Topmost composition is aliphatic acid in the edible oil and fat, difference according to carbon chain lengths can be divided into aliphatic acid short chain, medium chain and LCFA, and be divided into according to the difference of its saturation degree: saturated fatty acid (saturated fatty acid, SFA), monovalence unrighted acid (monounsaturated fatty acid, MUFA), polyvalent unsaturated fatty acid (polyunsaturated fatty acids, PUFA).
Saturated fatty acid (SFA): refer to not contain in the fatty acid molecule unsatisfied chemical bond.
Unrighted acid: contain unsatisfied chemical bond in the fatty acid molecule.
Monounsaturated fatty acids (MUFA): the aliphatic acid (such as oleic acid) that contains two keys in the molecule.
Polyunsaturated fatty acid (PUFA): the aliphatic acid (such as linoleic acid, leukotrienes) that contains two and above pair keys in the molecule.In polyunsaturated fatty acid, what important biomolecule meaning was arranged is n-3 and n-6 series.
Essential fatty acid (essential fatty acid, EFA): human body can not self synthesize, and must be called essential fatty acid by the aliphatic acid of food supply, comprises two kinds of linoleic acid, alpha-linolenic acids.
Functional polyunsaturated fatty acid:
Polyvalent unsaturated fatty acid is again polyenoic acid, refers to contain two or more pairs of keys, carbon chain lengths at 18 or 18 aliphatic acid more than the carbon atom, and they are main body and the core of functional fatty acid research and development.Two keys the more, degree of unsaturation is higher, nutritive value is also higher.Along with the reach of science, some polyunsaturated fatty acid is further appreciated the effect of human body, particularly the linoleic acid in docosahexenoic acid, eicosapentenoic acid and the general vegetable oil (normal coexist with leukotrienes) etc. is the polyunsaturated fatty acid of representative, at present more and more cause people's attention, be called by the nutritionist " functional grease ".
The classification of polyunsaturated fatty acid:
Functional polyunsaturated fatty acid is divided into two large classes according to structure:
N-3 (claiming again ω-3) is polyunsaturated fatty acid:
Refer to count from fatty acid carbon chain methyl end, first pair key appears at the 3rd polyunsaturated fatty acid on the carbon atom, mainly comprises:
Alpha-linolenic acid (α-linolenic acid, α-LNA),
Eicosapentaenoic acid (eicosapentaenoic acid, EPA),
DHA (docosahexaenoic acid, DHA).
N-6 (ω-6) is polyunsaturated fatty acid:
Refer to count from fatty acid carbon chain methyl end, first pair key appears at the 6th polyunsaturated fatty acid on the carbon atom, mainly comprises:
Linoleic acid (finoleic, LA),
Gamma-Linolenic acid (γ-linolenic acid, γ-LNA),
Arachidonic acid (arachidonicacid, AA).
The physiological function of polyunsaturated fatty acid:
In the thirties, if it is found that lack in the food of animal that vegetable oil is will genesis and development bad, skin abnormality, immunity is poor even the low inferior pathology of fecundity, these phenomenons will be alleviated after replenishing vegetable oil in the food, tracing it to its cause, mainly is the effect of the linoleic acid plus linolenic acid in the vegetable oil.Linoleic acid and a-leukotrienes can only can not synthesize in vivo from external world's picked-up, therefore are called as essential fatty acid.Polyunsaturated fatty acid is not only because the linoleic acid of n-6 series and the leukotrienes of n-3 series are the indispensable essential fatty acids of human body, the more important thing is because several polyunsaturated fatty acids of being taken in metabolic conversion or the specific food resource in vivo by them play a part very important in Human Physiology.
Oleic acid:
Monovalence unrighted acid content in vegetable oil take oleic acid as representative is higher.The external up-to-date viewpoint of nutrition circle is thought: oleic acid can reduce T-CHOL and bad cholesterol in the blood.Not being both of it and polyunsaturated fatty acid maximum reducing T-CHOL, bad cholesterol simultaneously, but do not reduced useful cholesterol.Polyunsaturated fatty acid also can reduce useful cholesterol when reducing T-CHOL and bad cholesterol.Nutrition circle calls oleic acid in " safe aliphatic acid ", and the content of oleic acid how much, is the important symbol of evaluation edible oil quality.
Linoleic acid:
Linoleic acid is as the essential fatty acid that is identified the earliest and important polyunsaturated fatty acid, content in our daily edible most greases is all more than 9%, and all higher at the content of main edible vegetable oil and fat and soybean oil, cotton seed oil, walnut oil, rape seed oil, sunflower oil, peanut oil, rice bran oil, sesame wet goods edible oil and fat.Linoleic acid is the aliphatic acid of needed by human, and it is the important component that consists of the human body cell film, and is useful to retina and corticocerebral growth simultaneously.The dyslipidemias increase can cause atherosclerotic in the blood, and linoleic acid can be combined with cholesterol, can reduce the precipitation that cholesterol is combined with saturated fatty acid.So linoleic acid has the reduction body's cholesterol, and is hypotensive, softening blood vessel prevents and improves the effects such as atherosclerotic.Long-term eating can strengthen cardiovascular function, has the prevention skin disease, improves immunity of organisms, promotes the wound healing texts.
Alpha-linolenic acid:
Alpha-linolenic acid has certain content in walnut oil, soybean oil, rape seed oil, sunflower oil.For linoleic acid, the resource of alpha-linolenic acid and daily availability are very different, but have more alpha-linolenic acid resource in some algae and microorganism.Linoleic acid and a-leukotrienes can only can not synthesize in vivo from external world's picked-up, therefore are called the essential fatty acid of human body.(α-LNA) is respectively the precursor of n-6 and n-3 series fatty acid, prolongs through a series of carbochain in vivo and desaturation effect derivation generates other PUFA for linoleic acid (LA) and alpha-linolenic acid.The n-3 polyunsaturated fatty acid also can be called omega-3 polyunsaturated fatty acids (ω-3PUFA).Linolenic physiological function: eliminate new vascular disorder, comprise the reduction cholesterol levels, reduce blood pressure, reduction triglycerides, enhancing blood platelet condense; Prevent diabetic syndrome; Auxiliary for treating cancer; The prevention skin disease; Anti-ageing; The functions such as regulation of physiological functions disorder.Leukotrienes is widely used in the health food as a kind of important function factor.
The nutritive value of walnut oil:
1. the polyunsaturated fatty acid that contains 90%-95% in the walnut oil.Except supplying with a large amount of heat energy of human body, can also adjust the ratio of high and low density lipoprotein cholesterol in the human plasma, can increase the equilibrium concentration of the HDL HDL (good cholesterol) in the human body behind the edible walnut oil, to guarantee that human body is to the requirement of cholesterol.But also can reduce the concentration of low-density lipoprotein LDL (bad cholesterol) in the blood plasma, excessive to prevent cholesterol in human body.
2. the polyunsaturated fatty acid that contains in the walnut oil can be divided into omega-fatty acid (being mainly leukotrienes) and ω-6 aliphatic acid (being mainly linoleic acid).These are the aliphatic acid that human body is necessary and human body can not self synthesize again.So also be called essential fatty acid, according to world medical circle many decades studies have shown that the essential fatty acid of human body: when the ratio of the essential fatty acid content omega-fatty acid of human body and ω-6 aliphatic acid was 1: 4, various diseases was difficult to the invasion human body.And the ratio of contained essential fatty acid just in time is 1: 4 in the olive oil, and is similar with human milk.
3. contain abundant micro-squalene, Flavonoid substances and polyphenolic substance in the walnut oil, can strengthen the immunity of human body, delay senility.
4. its every hectogram also contains 0.03 to 0.36 milligram beta carotene, and the vitamin E of 1.2-43 milligram reaches the multiple liposoluble vitamins such as vitamin A, D, F, K, is the necessary nutriment of human organ.Therefore current medical circle is known as walnut oil and benefits one of healthy edible oil most.
Walnut oil and health care:
Long-term edible walnut oil can reach following effect:
1. improve digestive system function: it has the function that reduces hydrochloric acid in gastric juice, stops the diseases such as gastritis and duodenal ulcer occur;
2. protection bone: the natural in the walnut oil and ω-3 can promote bone growth, keeps bone density, reduces the skeleton bulking that causes because of free radical;
3. give protection against cancer: can prevent some canceration (breast cancer, prostate cancer, colon cancer, the cancer of the uterus): omega-fatty acid can also increase the effect of radiotherapy and chemotherapy;
4. radiation proof: often make the computer user more regard it as the good merchantable brand of health-care and skin-care;
5. mother and baby's food: in the nutritional labeling of walnut oil, the leukotrienes that human body can not synthesize, linoleic ratio are similar with breast milk, very easily absorb, and can promote growing of the neural and bone of infant, are pregnant woman's super nutritive product and fetal growth agent;
6. anti-ageing: the antioxidant that contains can be eliminated interior free yl, prevents brain aging, promotes longevity;
7. prevention cardiovascular and cerebrovascular disease: protect from many aspects cardiovascular system.
Vitamin E:
Vitamin E is the summation of tocopherol and tocotrienols.Vitamin E belongs to liposoluble vitamin.Can promote the secretion of corpus luteum hormone in the human body, have the antisterility activity, so claim again C antisterility vitamin.Vitamin E has oxidation resistant effect.Can reduce the harmful peroxide radical level of cell membrane in the human body, prevent from producing senile plaque expelling owing to the free of peroxylradicals makes Skin Cell impaired.Also have the acceleration cell division, prevent cell ageing, delaying human body caducity keeps the effect in body youth.Vitamin E suppresses the effect that lipid peroxide is deposited in shape thrombus on the blood vessel in addition, thereby but prevention of arterial is atherosis.
DHA (DHA) is commonly called as " docosapentaenoic acid ".DHA is important nutritional labeling in infant's nerve cell growth course; With the degree of being quick on the draw in the infant growth process much relations are arranged, so DHA is called as clever aliphatic acid.The fetal birth initial stage, DHA is in large quantities accumulation in human brain tissue until three years old.DHA becomes the abundantest polyunsaturated fatty acid in people's brain cell.It is the main component of brain grey matter and neuroretina, and the content of DHA in optic cell and retinal tissue is up to 40-47%, and the normal function of retinal rod light receptor is played an important role.If lack DHA, can make DHA content decrease in the retinal tissue, thereby cause eyesight and resolving power to descend.Human brain fat accounts for 60%, and wherein DHA accounts for 10% of fat.In optic nerve, retina, account for fat content more than 40%.Enough DHA absorb can cover the required nutrition of brain, increases acuity and the adaptability to changes of brains.Simultaneously, DHA also can assist more healthy nervous system of construction, causes strengthening memory and thinking, improves intelligence.
In the human body of growing up, have from the synthetic ability that is converted into DHA of the leukotrienes of taking in, thus the additional enough a leukotrienes of pregnant woman, just can produce in vivo a large amount of DHA, enter liver and the brain of fetus by placenta.But the efficient of this path for transformation is very low in fetus and infants, and the synthetic quantity of DHA is not enough to satisfy the demand of body development, so must additionally replenish from food.Can say, DHA is the essential fatty acid of children's brain growth.
DHA has obvious facilitation to the brain development of fetus, infant especially.And traditional animal DHA (being deep sea fish oil), because containing the EPA that exceeds standard, EPA suppresses infant's ontogeny, affect bone, neurodevelopment growth, the promotion sex premature, thereby pregnant woman, women breast-feeding their children, children can not eat.World Health Organization (WHO) requires DHA in the polyunsaturated fatty acid of children taking: EPA ratio is greater than 10: 1.DHA in the little algae oil of vegetalitas DHA: EPA ratio is 40: 1, substantially exceeds the requirement of the World Health Organization (WHO).It is the children DHA supplementary source of the unique approval of U.S. food and drug safety Surveillance Authority (FDA).
Phytosterol:
Phytosterol be from corn, soybean grease through physical purification and getting, have the characteristics such as be of high nutritive value, physiologically active is strong.Phytosterol can reduce by reducing cholesterol the risk of cardiovascular disease.It is widely used in the fields such as food, medicine, cosmetics, growth of animal agent and sheet processing, printing, weaving, and is particularly very general as food additives in Europe, is widely used in the food to reduce body's cholesterol.
Phytosterol has stronger antiinflammatory action to human body, has can suppress human body to effects such as the absorption of cholesterol, the katabolism of promotion cholesterol, the biochemistry of inhibition cholesterol synthesize; The heart disease that is used for prophylactic treatment coronary atherosclerosis class has obvious curative effect to treatment ulcer, Skin Squamous Cell Carcinoma, cervical carcinoma etc.; Can promote wound healing, make the muscle hyperplasia, strengthen the capillary circulation; Also can be used as the inhibitor that gall stone forms.Phytosterol has good antioxygen, can make food additives (antioxidant, nourishing additive agent); Also can be used as growth of animal agent raw material, promote growth of animal, promote animal health.
Additional phytosterol can obviously reduce T-CHOL in the blood (TC) and low-density lipoprotein (LDL) content, and do not reduce HDL (HDL) and triglyceride content, LDL/HDL ratio is reduced, and without any obvious side effect, phytosterol has adjuvant treatment effect to hyperlipidemia.Therefore, generally believe that now the phytosterol of absorption or additional capacity helps to reduce the incidence of disease of crowd's coronary heart disease.Studies have shown that, phytosterol has certain inhibitory action to generation and the development of some cancer of body, such as breast cancer, cancer of the stomach, intestinal cancer etc.
Phytosterol is a kind of blending constituent, comprising stigmasterol, sitosterol, campesterol etc.Because phytosterol is nontoxic, it is new resource food for the existing approved of China, can directly join in the food (or beverage), with the nutritive value of improving product.In recent years, more Hesperian food manufacturers have successively developed a series of health foods that contain phytosterol, comprise margarine (margarine), salad dressing, sour milk, chewing gum, biscuit, beverage and other various health foods that contain phytosterol.Behind the launch, quite be subjected to local consumer's welcome.The purposes of phytosterol maximum is the food supplement as norcholesterol, reducing blood lipid.Along with the raising of people's living standard, cardiovascular patient day by day increases, and according to World Health Organization's statistics, angiocardiopathy has become human No.1 killer.Angiocardiopathy results from cholesterol in the deposition of cardiovascular inwall, and for many years, doctors are making great efforts to allow family accept a kind of like this viewpoint always, the intake of cholesterol in the control diet, your health that will more likely often keep healthy.A large amount of scientific facts proved already, and phytosterin ester can stop stomach to the absorption of cholesterol, thereby reduced the concentration of Blood Cholesterol.Phytosterin ester is to be made by esterification by phytosterol and vegetable fatty acids.Wherein phytosterol is the mixture of cupreol, campesterol and stigmasterol, derives from the deodorization distillate of soybean oil, vegetable seed wet goods vegetable oil.This product is a kind of natural multi-functional physiological activator, and is safe, is a kind of functional food ingredient of desirable reduction cholesterol.Phytosterin ester was used as functional food ingredient by FDA (FDA) approval in 2000.FDA thinks, will take in for each person every day the above phytosterin ester of 1.3g and can reach the purpose that reduces cholesterol.
Medium-chain fatty glyceride (hot certain herbaceous plants with big flowers acid glyceride):
Medium-chain fatty glyceride is called for short MCT, is widely used in numerous food preparation and processing, is a kind of aliphatic acid that contains the sad and C10:0 certain herbaceous plants with big flowers acid of C8:0, is referred to as medium-chain fatty glyceride.
Medium-chain fatty glyceride extracts from coconut oil or in the palm-kernel oil.They are mixtures of saturated triglycerides, and main is sad (C8H16O2) and certain herbaceous plants with big flowers acid (C10H20O2), and their content is not less than 95%, be a kind of be water white transparency, free-pouring liquid.The difference of median chain triglyceride oil and long chain triglycerides maximum is its unique metabolic pathway: triglyceride is resolved into glycerine and aliphatic acid by bile and pancreatic secretion in duodenum, LCFA enter intestinal mucosa through behind the resterification with the Protein formation chylomicron, enter blood circulation by Lymphatic Circulation, excess intake can be stored in the adipose tissue; Medium chain fatty acid then directly enters liver by portal vein, and the oxidation energy supply is not stored in the adipose tissue in liver.When gall-bladder or pancreas normally when secretion of bile and pancreatic secretion, long chain triglycerides just can't absorb in metabolism, even and median chain triglyceride oil does not decompose, also can pass through intestinal mucosa access door vein, participate in normal metabolism, improve the absorption of other nutriment, such as mineral matter, essential fatty acid etc.
Medium-chain fatty glyceride can be applied in:
Baby milk powder can promote growing of infant, especially to early stage baby or underfed child.Such as the PediaSure of Abbott Laboratories, just added MCT.
Beverage and health products can satisfy the sportsman, the special population of the large or fat-reducing of physical training person's homenergic consumption.
The picked-up of medium-chain fatty glyceride (MCT) has the effect that the black alcohol of serum courage, the black alcohol of liver and gall are reduced, and because of edible higher fatty acid, that high cholesterol food causes artery sclerosis, DVT patient and obese patient, MCT can play special effect.Median chain triglyceride oil also has some superior physicochemical properties: oxidation stability, low viscosity etc.Usually utilize its stronger oxidation stability and low viscosity, diffusivity to replace beeswax and mineral oil to be used for raisins, the candy of transparent wrapper as antitack agent.The functional characteristic of medium-chain fatty glyceride has caused some experts and scholars' concern, and some research reports have been arranged, believe along with continuous popularization, therefore median chain triglyceride oil is bound to become another focus in the functional food additives, and the health-product market of China also can be and more flourishing.
Compared with common vegetable oil, the molecular weight of MCT is lower, and smoke point about about 160 degrees centigrade, therefore may be used for baking or frying greatly hardly.In the active batching of the pH value food larger than low moisture or lipase, all oils all is hydrolyzed into free fatty and glycerine.The aliphatic acid of long-chain does not exert an influence to food without any taste.
