A kind of edible camellia oil blend oil and preparation method thereof
Technical field
The invention belongs to food processing field, relate in particular to a kind of edible health ready-mixed oil and preparation method thereof.
Background technology
Tea oil obtains from Theaceae tea oil tree seed, do not contain human harmful substances such as aflatoxin, erucic acid, gossypol, be rich in natural VA, VD, VE, VK, carrotene, and various active compositions such as Tea Polyphenols, squalene, have the blood vessel elasticity of enhancing and toughness, delay atherosclerotic, increase the stomach absorption function, promote endocrine body of gland hormone secretion, prevent that nervous function from descending, and improves effects such as body immunity.
China's dietary fat is mainly derived from edible oil and fat, three kinds of the fatty acid oils in the natural oil, saturated fatty acid (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acid (PUFA).Monounsaturated fatty acids content height in the tea oil is found according to external EPDML investigation, be tangible negative correlation between the monounsaturated fatty acids in the meals and the death rate of coronary heart disease, but its aliphatic acid is formed the ratio that does not still meet the human nutrition demand.In recent years, people begin to recognize that too much absorption SFA causes that easily cholesterol raises atherosclerotic and coronary heart disease; And too much picked-up PUFA increases the danger of coronary artery thrombus, causes the damage of arterial wall, promotes the formation of artery sample sclerosis, and easily produces lipid peroxidation and cause aging, even may be carcinogenic.So three's constituent ratio and hyperlipidemia, atherosclerotic, angiocardiopathy are in close relations.
At present, the ready-mixed oil that sell the domestic market all is to be matrix oil with the bulk edible oil, and edible oils allotment that adding another kind or more than one have functional characteristic forms.The various fatty acid proportions of these ready-mixed oils do not meet the aliphatic acid matching criterion that international nutritionist proposes.In recent years, consider the product that balanced fatty acid is taken in though some have also occurred.As the imperial fish of gold two generations ready-mixed oil, the ratio that has solved MUFA and PUFA is 1: 1 a problem." a load mill board " special edible oil that Shanghai one load mill nutrition grease Co., Ltd releases, the ratio of ω-6 and ω-3 among the PUFA of having solved are 5: 1 problem.But the ratio of MUFA and PUFA be 1: 1 this be the notion before the more than ten years, along with the further investigation to lipid nutrition, three kinds of fatty acid proportions of SFA, MUFA that present international nutritionist generally admits and PUFA are 1: 6: 1.And up to now, also do not have a kind of ready-mixed oil product can reach this proportion requirement, more there is not a kind of ready-mixed oil product to solve simultaneously that the ratio of ω-6 and ω-3 is 4~6 in ratio that three kinds of aliphatic acid form and the polyunsaturated fatty acid: 1 problem.Therefore, study MUFA and the PUFA matching criterion that satisfies NI and propose, the ready-mixed oil that is fit to the aliphatic acid reasonable mixture ratio of body metabolism demand, have very important significance.The World Health Organization and FAO's suggestion, the ratio of three kinds of aliphatic acid was advisable with 1: 6: 1 in the edible oil and fat, reach the saturated fatty acid that the World Food Programme and Chinese Soclety of Nutrition in 2002 propose: monounsaturated fatty acids: polyunsaturated fatty acid is 1: 6: 1, and wherein ω in the polyunsaturated fatty acid-6 and ω-3 are the perfect ratio of dietary fatty acid of 4~6: 1 recommendation.And at present, the research of this respect does not still have disclosed related data.
Summary of the invention
An object of the present invention is to provide a kind of new edible camellia oil blend oil, solve simultaneously that the ratio of ω-6 and ω-3 is 4~6 in ratio that three kinds of aliphatic acid form and the polyunsaturated fatty acid: 1 problem.
Another object of the present invention provides the preparation method of described edible camellia oil blend oil.
Technical scheme of the present invention provides a kind of edible camellia oil blend oil, form by following weight percentage feedstock oil: refining tea oil 40%~70%, rapeseed oil 25%~45.5%, peanut oil 1%~10%, soybean oil 0%~10% and roselle seed oil 0%~10%.
As several preferred versions, described edible camellia oil blend oil is made up of following weight percentage feedstock oil: refining tea oil 54.34%, rapeseed oil 43.48% and peanut oil 2.18% or refining tea oil 45.5%, rapeseed oil 45.5%, soybean oil 4.5% and peanut oil 4.5% or tea oil 70%, rapeseed oil 28%, peanut oil 1% and roselle seed oil 1% or tea oil 50%, rapeseed oil 40%, peanut oil 5% and roselle seed oil 5%.
The present invention provides the preparation method of described edible camellia oil blend oil simultaneously, may further comprise the steps:
(1) aliphatic acid of measuring feedstock oil is formed;
(2) pro rata is calculated the consumption of feedstock oil, takes by weighing various feedstock oils;
(3) feedstock oil mixes, stirs.
The mensuration that the aliphatic acid of the described feedstock oil of step (1) is formed is to adopt gas chromatograph-mass spectrometer to measure.Described feedstock oil refers to refining tea oil, rapeseed oil, peanut oil, soybean oil and roselle seed oil.
Step (2) is formed according to the aliphatic acid of the feedstock oil that step (1) is measured, and according to saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid=1: 5.3: 1.1, wherein, ω-6: ω-3=6: 1 proportional meter is calculated the consumption of various feedstock oils.
The present invention is according to the kind and the content of different vegetable fatty acids, utilize tea oil monounsaturated fatty acids content height, tea oil and rapeseed oil, soybean oil, peanut oil, roselle seed oil or other plant wet goods are carried out scientific allocation, make saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid reaches 1: 6: 1 optimal proportion substantially, becomes the edible blend oil with specific function and nourishing healthy.The aliphatic acid of described ready-mixed oil consists of: saturated fatty acid: monounsaturated fatty acids: polyunsaturated fatty acid=1: 5.3: 1.1, wherein, ω-6: ω-3=6: 1.
The present invention compared with prior art, its beneficial effect is:
(1) the present invention's different according to different natural edible-plant oil institute's fatty acids kind and quantity, with human body dietary fat acid balance is principle, with tea oil and rapeseed oil, soybean oil, peanut oil, roselle seed oil or other plant wet goods cooperate by a certain percentage, through scientific allocation, changing aliphatic acid forms, to satisfy the needs of different crowd, edible camellia oil blend oil aliphatic acid is formed SFA: MUFA: PUFA near 1: 6: 1 optimal proportion, and reach the requirement of ω in the polyunsaturated fatty acid-6: ω-3=4~6: 1, meet human body dietary fatty acid equilibrium principle, become the nutrient blend oil that has particular adjustments and improve Human Physiology and pathology, satisfy the demand of health;
(2) edible camellia oil blend oil raw material sources of the present invention is extensive, and price and cost is reasonable;
(3) technology of the present invention is simple, and is simple to operate easy, the promotional value height.
