Description
Technical field
The present invention relates to a kind of fat or oil composition, a kind of functional grease compositions with health-care effect, belong to oils and fats technical field.
Background technology
Hyperlipidemia, hypertension are present epidemic diseases, and blood fat reducing, blood pressure lowering are present popular topics, and hyperlipidemia refers to that in blood, VLDL, LDL increase, and plasma cholesterol is higher than 140mg/100ml higher than 230mg/100ml and triglyceride.In the modern life, hyperlipidemia, fatty liver have become a kind of commonly encountered diseases of middle-aged and elderly people, and along with growth in the living standard, sickness rate has obvious ascendant trend, and has the trend of rejuvenation.In daily life, if it is possible to preferably balanced diet structure just can obtain preferable lipid-lowering effect, the picked-up of the particularly often edible nutrition in oils and fats.
Hyperlipidemia is one of factor causing hypertension, the tunica intima of people with hyperlipidemia can increase gradually formation of deposits yellow speckle along with blood fat, and speckle accumulation can form narrowed blood vessels that sclerosis of blood vessels makes, resistance of blood flow increase, vessel wall elasticity weaken and cause blood pressure to raise.The formation of hyperlipidemia is long-term process.The general non-evident sympton of hyperlipidemia shows, and ill awareness is low.If but people is chronically at hyperlipidemia state, the state of an illness can increase the weight of and can induce the disease of the cardiovascular and cerebrovascular disease such as atherosclerosis, coronary heart disease to send out, thus has a strong impact on health, the life security of harm people.Hyperlipidemia is also one of major reason causing fatty liver.Human body blood fat is chronically at abnormality can make liver lipids accumulation more than its metaboilic level, causes lipid aggregation excess thus damages liver function and can progressively develop into the diseases such as liver cirrhosis.
In prior art, CN201110169851.5 open a kind of family balance formula oil, being made up of camellia seed oil, Semen Maydis oil, Oleum Vitis viniferae, Semen Lini oil, walnut oil, mixed tocopherol, this family's balance formula oil is cooked good stability, is had enhancing development effect and auxiliary effect for reducing blood fat.But finding through research, its companion matrix blood fat still has to be strengthened.CN200810235299.3 discloses a kind of mixed oil, and it is made up of 8-85% cannabis oil and other edible vegetable oil of 15-92%；Wherein, edible vegetable oil is that one or more in totally 13 kinds such as safflower oil, Semen Maydis oil, oleum lini are constituted；In this mixed oil, the weight ratio of n-6 and n-3 is 4-6:1, and satisfied fatty acid is less than 15%, and its balanced fatty acid is the most not reasonable, and the hypolipemic function of the mixed oil of composition concrete disclosed in it is the best.
Although, the compound oils and fats of health care is the most all to be formed by the oils and fats interworking of those common plant sources, but, different combinations, the performance of the product obtained but differs greatly, it is respectively arranged with and lays particular stress on, according to the dietary requirement of current China, there is the health care of good Adjust-blood lipid effect and be combined oils and fats and still have multiple product to be developed.
The leading indicator affecting oils and fats shelf life stability is exactly the non-oxidizability of oils and fats, and Oxidation of Fat and Oils is grease deterioration or the rich topmost performance of grease-contained food, is eaten for a long time and is easily caused cell function exhaustion or even the various diseases of tissue necrosis initiation.For antioxidant BHA, BHT, GP etc. of synthetic, safety is constantly subjected to the query of people, the most effectively the focus of oil-control oxidation also always research.
Fatty acid, as the main component of edible oil and fat, with a length of standard of carbochain, can be divided into long-chain fatty acid, medium-chain fatty acid and short-chain fatty acid.Common edible oil mostly is long-chain fatty acid, generally refers to the fatty acid that carbon number is 12～22, such as EPA and DHA, is mainly derived from animal and plant fat, microbial grease, fish oil and algae oil.And the satisfied fatty acid that medium-chain fatty acid is made up of 8～12 carbon atoms, there is the functional characteristic being different from long-chain fatty acid, it is to naturally occur in nature but the less fatty acid of content.Medium-chain fatty acid is rapidly absorbed, because having, the characteristic that burning conversion is energy, reduces accumulation of body fat and the health care of body weight of keeping fit so having.
Therefore, exploitation has rational fatty acid composition, has the replacement everyday home oil of the health-care oil reducing blood fat effect, is formed with important meaning for controlling hyperlipidemia, and in prior art, there is the oils and fats of preferably reduction blood fat effect often in terms of antioxidation, show poor.CN103054045A discloses the health plant fat or oil composition with hypolipemic function, but this oils and fats exists bigger problem in terms of oxidation stability；CN1096641A discloses oenothera odorata oil health food, but the effect of the regulation blood fat of this food inconspicuous, and the less stable of oils and fats.
Summary of the invention
For technical problem present in prior art, the invention is characterized in that rational technological means, selection, the improvement of technical method including raw material, while improving oils and fats health-care effect, increase its anti-oxidation efficacy, it is therefore intended that provide a kind of edible health fat or oil composition with good effect of regulating blood fat.
The technical solution used in the present invention is as follows: a kind of fat or oil composition, it is to prepare with basic grease and conjugated linoleic acid glyceride and the vitamin E being added in basic grease for raw material, the total addition level of conjugated linoleic acid glyceride and vitamin E is the 0.5% ~ 4% of fat or oil composition quality, and the conjugated linoleic acid glyceride added and the mass ratio of vitamin E are 1-8:2-15.
Described basic grease can be the oils and fats that this area is common, several as in soybean oil, Petiolus Trachycarpi oil, Oleum Cocois, palm-kernel oil etc..Preferably, described basic grease is the combination of Oleum Cocois, palm-kernel oil and Testa oryzae oil, and Oleum Cocois, palm-kernel oil and the Testa oryzae oil oils and fats mass content proportioning in basic grease is 25-45%, 10-40% and 10-65%.
As follows as further selectable technical scheme: a kind of fat or oil composition, prepare with basic grease and active component for raw material, wherein, basic grease content in fat or oil composition is 73%-95%, and active component content in fat or oil composition is 5-27%.
Described basic grease is Oleum Cocois, palm-kernel oil and Testa oryzae oil, and Oleum Cocois, palm-kernel oil and the Testa oryzae oil mass content proportioning in basic grease is respectively 25-45%, 10-40% and 10-65%.
