Technical Field
The invention relates to the technical field of food, in particular to an unsaturated fatty acid-nervonic acid compound solid beverage and a preparation method thereof.
Background
Omega-3 unsaturated fatty acids are a group of polyunsaturated fatty acids, mainly including several classes of alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), stearic acid (SDA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA). The omega-3 can promote the cardiovascular health, relieve arthritis and relieve joint swelling and pain, and DHA is an essential component for forming a brain cell membrane, can maintain the brain health, improve the special injection force and relieve the pressure; in addition, the omega-3 can also eliminate migraine, make the skin moisturize and keep healthy, reduce blood sugar and prevent diabetes and the like.
Omega-6 unsaturated fatty acids are also a group of polyunsaturated fatty acids, including Linoleic Acid (LA) and arachidonic acid (ARA), omega-6 is vital in the human body, cholesterol must be combined with the Linoleic Acid (LA) of omega-6 for proper functioning and metabolism; unsaturated fatty acids omega-6 and omega-3 in the human brain account for half each; prostaglandin PGE2 produced by arachidonic acid (ARA) from omega-6 is a hormonal substance essential for many vital functions of the human body.
Nervonic acid known as tetracosan-cis-15-enoic acid, an unsaturated fatty acid containing 24 carbon atoms and 1 double bond, which is present in nerve tissues and fish oils, is a component of cerebroside. Nervonic acid has effects of promoting brain development, improving memory, delaying aging and treating brain diseases.
The nervonic acid has been extracted from acer truncatum seeds in the prior art and used as a raw material for preparing food containing high content of nervonic acid, but the inventor finds that the combination of nervonic acid and other fatty acid in the prior art should not improve the activity of cerebral neurons.
Disclosure of Invention
The invention aims to provide an unsaturated fatty acid-nervonic acid compound solid beverage and a preparation method thereof, wherein a specific supercritical extraction process is selected to extract unsaturated fatty acids of omega-3 and omega-6 from flaxseeds, and the unsaturated fatty acids and the nervonic acid extracted from acer truncatum seeds are compounded to prepare the unsaturated fatty acid-nervonic acid compound solid beverage, the prepared unsaturated fatty acid-nervonic acid compound solid beverage has high contents of the unsaturated fatty acids of the omega-3, the unsaturated fatty acids of the omega-6 and the nervonic acid, and the compounding of the unsaturated fatty acids, the unsaturated fatty acids and the nervonic acid can effectively improve the activity of cerebral neurons.
In order to achieve the purpose, the invention provides the following technical scheme:
in a first aspect of the present invention, there is provided an unsaturated fatty acid-nervonic acid complex solid beverage, comprising: the weight ratio is 3-5:3.5-5.5:90.5-92.5 of linseed extract, acer truncatum seed extract and auxiliary materials; wherein, the content of the omega-3 unsaturated fatty acid in every 5 g of the unsaturated fatty acid-nervonic acid compound solid beverage is not less than 100 mg, the content of the omega-6 unsaturated fatty acid is not less than 30 mg, and the content of the nervonic acid is not less than 7.5 mg;
the preparation method of the linseed extract comprises the following steps:
(a1) Crushing a flaxseed raw material, drying the flaxseed raw material with granularity of 8-40 meshes at 75-85 ℃ for 2.5-3.5 hours until the water content of the flaxseed is lower than 2%;
(a2) Extracting the unsaturated fatty acid omega-3 and the unsaturated fatty acid omega-6 in the dried flaxseed by adopting a supercritical fluid extraction method, wherein the supercritical fluid extraction process adopts reaction parameters as follows: the extraction pressure is 30-32Mpa, the separation temperature is 55-60 ℃, the extraction temperature is 45-50 ℃, and the extraction time is 3-4 hours;
the preparation method of the acer truncatum seed extract comprises the following steps:
(b1) Drying Acer Truncatum Bunge seeds at 60 deg.C for 1-3 hr, physically rubbing to remove shell, pulverizing to granularity of 10-40 mesh, and drying at 60 deg.C until the water content is less than 5%;
(b2) Extracting nervonic acid in the dried acer truncatum seeds by adopting a supercritical fluid extraction method, wherein the supercritical fluid extraction process adopts reaction parameters as follows: the extraction pressure is 31Mpa, the separation temperature is 61 ℃, the extraction temperature is 51 ℃, and the extraction time is 2 hours.
The linseed extract contains unsaturated fatty acid of omega-3 and unsaturated fatty acid of omega-6, and the acer truncatum seed extract contains nervonic acid.
In one or more embodiments, in the unsaturated fatty acid-nervonic acid complex solid beverage, the content of the omega-3 unsaturated fatty acid is the sum of the contents of alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA); the content of unsaturated fatty acid in omega-6 is the sum of Linoleic Acid (LA) and arachidonic acid (ARA).
In one or more embodiments, in the unsaturated fatty acid-nervonic acid complex solid beverage, the auxiliary material is sorbitol.
In one or more embodiments, in step (a 2), the extraction pressure is selected from 30MPa,31MPa, or 32MPa.
