Abstract
A linseed oil which is not easy to generate bitter taste and a preparation method thereof are characterized in that: the selected flaxseeds and the auxiliary cake are uniformly mixed according to a certain proportion, crushed, and then physically pressed, and the obtained flaxseeds oil is subjected to precipitation, dewaxing, filtering, storage and filling, so that the finished product flaxseeds oil which is not easy to generate bitter taste is obtained.
Description
Technical Field
The invention belongs to the field of food processing, and particularly relates to linseed oil which is not easy to generate bitter taste and a preparation method thereof.
Background
Flax (Linum usitatissimum l.) is a herb of the family flax, also known as flax. Linseed oil is obtained from flaxseeds and is becoming more and more interesting because it is rich in alpha-linolenic acid, a fatty acid (up to 50-60%) which is essential for humans. Alpha-linolenic acid belongs to omega-3 series of unsaturated fatty acids, which cannot be synthesized by human body and must be supplemented from diet. Research shows that alpha-linolenic acid can esterify cholesterol to metabolize out of human body, reduce blood viscosity, improve blood microcirculation and inhibit thrombosis. Because the blood system is closely related to various functional organs of the whole body, the alpha-linolenic acid also has the functions of preventing and relieving hyperlipidemia, hypertension, obesity, atherosclerosis, myocardial infarction, cerebral infarction, apoplexy, senile dementia and the like. Alpha-linolenic acid can be synthesized, metabolized and converted into living active factors DHA, DPA, EPA and the like necessary for organisms in vivo, and especially DHA is closely related to the brain intelligence development of infants.
Although linseed oil has high nutritive value, cyclic peptide substances in linseed oil limit the wide use of linseed oil to a certain extent. The cyclic peptide substance in the linseed oil is a hydrophobic cyclic oligopeptide consisting of a plurality of amino acids, also called as the linseed cyclic peptide, the absorption of amino acid nutrient substances by human bodies can be increased when the cyclic peptide exists in the linseed oil, but the cyclic peptide is easily oxidized in the linseed oil, particularly the cyclic peptide containing methionine is gradually oxidized into methionine sulfoxide, so that bitter taste is generated, the taste is affected, even further oxidized into methionine sulfone, the bitter taste is heavier and even the linseed oil cannot be eaten as the oxidation degree is increased, and part of people cannot discard the purchased linseed oil because the linseed oil is bitter and cannot be eaten, so that the waste is also limited, and the wide use of the linseed oil is further limited.
In recent years, as the effect of alpha-linolenic acid in linseed oil is increasingly known and emphasized, linseed oil is also increasingly known, but linseed oil is easy to bitter and always is a neck problem in linseed oil popularization. The traditional technology of adding antioxidants such as TBHQ, BHA, BHT, vitamin E and the like into the edible oil has obvious effect of preventing the oxidation rancidity of fatty acids in the edible oil, but has very little effect of preventing cyclic peptide substances in the linseed oil from oxidizing and becoming bitter.
Some flaxseed oil debittering techniques are also presented, but there are also some problems. The traditional ' four-removal ' process, as well as the method for refining pressed linseed oil by adopting the patent ' CN201010535505. X-solid adsorption and vacuum filtration oil ', ' CN106753781A ' a method for removing bitter taste in linseed oil ', ' CN105112157B linseed oil debitterizing and deodorizing treatment method ', ' CN201710605443.7 ' a linseed oil refining method and the like, although the problem that the linseed oil can be bitter is solved by removing cyclic peptide in the linseed oil, the vitamin and other trace nutrients in the linseed oil are also partially or almost completely removed, the nutritive value of the linseed oil is reduced, the oxidation and deterioration of alpha-linolenic acid are easier to be caused, and at least one filter medium of activated clay, diatomite, attapulgite, alumina and the like is used in the processing process, the filter media contain various heavy metals with higher content, so that secondary pollution of linseed oil can be caused, although the strict production process of exogenously introduced heavy metals can reach the national standard, compared with untreated linseed oil, the heavy metal content is obviously increased, even the heavy metal content in activated clay, diatomite and attapulgite is greatly different, the condition that the heavy metal content in the produced linseed oil product exceeds the standard is easily caused, and then the problem that the heavy metal exceeds the standard is likely to be caused by blending or other modes for reaching the standard. The alumina media used in the "CN106753781a method for removing bitter taste in linseed oil" patent may also lead to increased uptake of aluminum by the human body, which is also harmful to the bones and nervous system of the human body. The linseed oil is taken as high-end edible oil, especially as a complementary food nutrition supplement for infants, and has large average intake per kilogram and long intake period, and the existing debitterizing process is obviously defective.
The patent CN106929143A is a cyanide-free and bitter-free cold-pressed linseed oil production technology, the method for removing bitter substances in linseed oil is characterized in that the active carbon or silica gel with very low heavy metal content is used for removing bitter substances respectively to reserve alpha-linolenic acid, the potential safety hazard of heavy metals is reduced, and especially the silica gel is used repeatedly to reduce heavy metal pollution, but both the two processes have the defect of reducing vitamin E and other micronutrients in linseed oil, and especially the reduction of vitamin E is easier to oxidize the alpha-linolenic acid in the linseed oil in the storage process, so that the nutritive value of the linseed oil is reduced.
Disclosure of Invention
Aiming at the problems in the background art, the invention provides a preparation method of linseed oil which is not easy to generate bitter taste, and the linseed oil which is not easy to generate bitter taste is prepared by the method, and simultaneously exogenous heavy metal or other harmful substances are not introduced in the preparation process, vitamin E and other micronutrients in the linseed oil are not removed, and the obtained linseed oil is purely natural, green and healthy, high in quality and aromatic. The preparation method is simple, practical, low in cost and easy for large-scale industrial production.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a linseed oil which is not easy to generate bitter taste and a preparation method thereof are characterized in that: uniformly mixing selected flaxseeds and auxiliary cakes (one or more of sunflower seed cakes, peanut seed cakes, walnut kernel cakes, bean cakes, almond cakes and pumpkin seed cakes after oil is physically squeezed) according to the proportion of the auxiliary cakes accounting for 5-49% of the total weight of the mixture, crushing, and then physically squeezing, wherein the obtained flaxseed oil is subjected to precipitation, dewaxing, filtering, storage and filling to obtain finished flaxseed oil which is not easy to generate bitter taste.
Further, in the preparation method, the selected flaxseed can be replaced by peeled flaxseed kernel.
Preferably, in the preparation method, the flaxseed and the auxiliary cake are uniformly mixed according to the proportion of the auxiliary cake accounting for 10-45% of the total weight of the mixture.

firstly, the flaxseeds and the auxiliary cakes are crushed and uniformly mixed and then fully contacted in the physical pressing process, and various trace active factors in the auxiliary cakes are brought into the flaxseeds oil, so that the flaxseeds oil is not easy to bitter due to the synergistic effect. The mechanism of the compound is that the compound can play a role in antioxidation of multi-factor synergism, inhibit the cyclic peptide in the linseed oil from being oxidized, or can synergistically keep the cyclic peptide in the linseed oil stable in structure, or can be realized through other effects, no matter which way the compound is used, the final result is that the linseed oil is not easy to generate bitter taste, compared with the original linseed oil, the time of the linseed oil to start bitter taste is obviously prolonged, the quality period of the linseed oil is prolonged, the problem that the linseed oil is easy to become bitter is solved to a certain extent, and the compound does not introduce secondary pollution of exogenous heavy metal or other harmful substances, and vitamin E and other trace nutrients in the linseed oil are not removed. In a comprehensive view, the linseed oil obtained by the invention is rich in nutrition, not easy to bitter, green and healthy, high in quality and aromatic in flavor.
And secondly, the auxiliary cake adopted by the invention is a slag cake after the dry oil is physically squeezed, the slag cake is added into the flaxseed to be squeezed, and the obtained pure flaxseed oil is not mixed with other edible oil compared with the raw materials of the non-squeezed oil, so that the blended oil is prevented from being squeezed, and the slag cake after the dry oil is fully contacted with the crushed flaxseed, so that more trace active factors enter the flaxseed oil to play a better role.
Again, the invention can not only prolong the bitter time of the linseed oil, but also inhibit the oxidative deterioration of the nutrient substance alpha-linolenic acid in the linseed oil.
Finally, the invention is simple but practical, has low cost, can be used for cold pressing and hot pressing, and the used auxiliary cake is finally discharged in the form of a slag cake, has little loss, can be used as feed, fertilizer, other raw materials for use and the like, has little increase in cost, and is easy for industrialized mass production.
