Contrast test
Meet the linoleic acid of southern crowd's taste and the edible oil of alpha-linolenic acid balanced proportion to be made, check in each oil product
Aliphatic acid composition the table of comparisons, prepare edible oil to choose suitable raw material.
The aliphatic acid composition of 1 each vegetable oil of table
One of camellia seed oil is southern specialty, while be also the oil product of southern crowd's often feeding, but analysis is found, tea seed
In the aliphatic acid composition of oil, mainly based on oleic acid, linoleic acid content takes second place the unrighted acid in tea-seed oil, substantially not
Containing alpha-linolenic acid.
Therefore, to produce nutrition-balanced edible oil, linoleic acid content can be added in into tea-seed oil and alpha-linolenic acid contains
The higher vegetable oil of amount, to reach mouthfeel and nutrition double requirements.
The aliphatic acid composition of 1 each plant of analytical table, finds linseed oil based on alpha-linolenic acid, fiery flaxseed oil is with linoleic acid
Based on, therefore, above two oil and peanut oil, which are reconciled, can not only increase alpha-linolenic acid content, but also can improve linoleic acid and contain
Amount, so the present invention has selected the numb seed of tea seed, linseed, fire to produce a kind of nutrition-balanced plant blend oil as raw material.
To find suitable reconciliation oil formula, following experiment is designed：
Comparative example 1：Tea seed 100%；
Comparative example 2：Tea seed 50%, linseed 50%；
Comparative example 3：The numb seed 50% of tea seed 50%, fire；
Comparative example 4：The numb seed 25% of tea seed 65%, fire, linseed 10%；
Comparative example 5：The numb seed 45% of tea seed 35%, fire, linseed 20%
Comparative example 6：The numb seed 25% of tea seed 50%, fire, linseed 25%；
Comparative example 7：The numb seed 30% of tea seed 50%, fire, linseed 20%；
Comparative example 8：The numb seed 45% of tea seed 50%, fire, linseed 5%；
Preparation method：The raw material of each comparative example are weighed according to above-mentioned mass percent correspondence, with reference to described in embodiment 1
Technological parameter and step produce ready-mixed oil.
The aliphatic acid composition and linoleic acid and alpha-linolenic acid ratio of 2 each comparative example of table
Analysis comparative example 2 is known, after tea seed and linseed mixing extraction, the content of polyunsaturated fatty acid of gained ready-mixed oil
Increase, especially alpha-linolenic acid content greatly improves, but since camellia seed oil and linseed oil Linoleic acid content are low, so only
Tea seed and linseed are reconciled, linoleic acid content can be caused relatively low, alpha-linolenic acid content is higher.
And comparative example 3 is shown, and after tea seed and the numb seed mixing extraction of fire, the monounsaturated fatty acids of gained ready-mixed oil and more
Unrighted acid ratio is close to 1:1, but since fiery numb seed Linoleic acid content is high, alpha-linolenic acid content is low, so causing to adjust
It is larger with oily Linoleic acid and alpha-linolenic acid content difference.
Comparative example 4 shows：After tea seed, linseed and the numb seed of fire are mixed extraction, content of polyunsaturated fatty acid increases,
And the content of linoleic acid and alpha-linolenic acid ratio is less than 4:1, but since tea seed mass percent (65%) is excessively high, so as to cause
In the ready-mixed oil of comparative example 4, monounsaturated fatty acids content is higher than the content of polyunsaturated fatty acid, accordingly, it is considered to list not
The content of saturated fatty acid and polyunsaturated fatty acid ratio most preferably 1：1, the mass fraction of tea seed is no more than 65%.
Similarly, comparative example 5 is analyzed it is found that when the mass percent of tea seed is 35%, and can cause in ready-mixed oil
Monounsaturated fatty acids content it is relatively low, therefore consider, the dosage of tea seed should be controlled in 40-60%.
The aliphatic acid composition of ready-mixed oil obtained by comparative example 6-8 is observed, is not difficult to find out, when tea seed dosage is controlled in 40-
When 60%, the mass ratio variation of linseed and the numb seed of fire will not lead to the ratio of monounsaturated fatty acids and polyunsaturated fatty acid
It is unbalance, but with the decline of linseed dosage and the increasing of the numb seed dosage of fire, in corresponding ready-mixed oil, linoleic acid and alpha-linolenic acid
Content ratio significant changes can occur, when fiery numb seed mass percent is less than 30% and when linseed mass percent is higher than 20%
The content of (comparative example 6), linoleic acid and alpha-linolenic acid is closer to, with optimal proportion 4:1 difference is farther out；And the numb seed quality hundred of fire
Score is more than 40% and linseed mass percent when being less than 10% (comparative example 8), and the linoleic acid content in gained ready-mixed oil is again
Considerably beyond alpha-linolenic acid, the two ratio has been higher than 4：1, still it is not the ready-mixed oil of most nutrient health, considers, obtain
Number is respectively 30-40% and 10-20% to the best in quality of fiery fiber crops seed and linseed respectively.
Finally, obtaining formula of the invention is：Tea seed 40-60%, fire fiber crops seed 30-40%, linseed 10-20%,
In above range, a kind of monounsaturated fatty acids and polyunsaturated fatty acid ratio are obtained close to 1:1, and linoleic acid and α-flax
Sour ratio is slightly less than 4:1 nutrient health ready-mixed oil.
