Preferably, the extractant comprises a mineral extractant; the mineral substance extracting agent comprises mineral substances with a nanometer microsphere structure, wherein the mineral substances comprise one or more of montmorillonite, diatomite and sepiolite.
In practical application, the mineral raw materials such as montmorillonite, diatomite, sepiolite and the like are ground, sieved and purified to obtain mineral raw material powder, and then the mineral raw material powder is dissolved in water, an inorganic solvent or an organic solvent to prepare the solution containing the mineral extracting agent.

More preferably, the extractant further comprises an enzyme extractant. The enzyme extractant is preferably an alkaline protease. In this example, the alkaline protease may be Novo protease, Carsberg protease, etc., which is not limited in this application.
Preferably, the composition of the flower raw material may be determined based on the kind of the flower raw material, and the extractant of the flower raw material may be determined based on the composition of the flower raw material.
Specifically, the extractant corresponding to the flower material may be determined based on its protein content.
For example, if the protein content of the flower raw material is less than 5% (excluding 5%), the corresponding extractant preferably comprises 0.1-3 parts by weight (e.g. 0.1, 0.5, 1, 1.5, 2, 2.5, 3 parts by weight) of enzyme extractant and 97-99.9 parts by weight (e.g. 97, 97.5, 98, 98.5, 99, 99.5, 99.9 parts by weight) of mineral extractant;

if the protein content is between 10% and 15% (including 10%, excluding 15%), the corresponding extractant preferably comprises 7-9 parts by weight (such as 7, 7.5, 8, 8.5, 9 parts by weight) of enzyme extractant and 91-93 parts by weight (such as 91, 91.5, 92, 92.5, 93 parts by weight) of mineral extractant;
if the protein content is between 15% and 20% (including 15%, excluding 20%), the corresponding extractant preferably comprises 10-15 parts by mass (such as 10, 11, 12, 13, 14, 15 parts by mass) of enzyme extractant and 85-90 parts by mass (such as 85, 86, 87, 88, 89, 90 parts by mass) of mineral extractant;
if the protein content is greater than 20%, the corresponding extractant preferably comprises 16-22 parts by weight (such as 16, 17, 18, 19, 20, 21, 22 parts by weight) of enzyme extractant and 78-84 parts by weight (such as 78, 79, 80, 81, 82, 83, 84 parts by weight) of mineral extractant.
Wherein, the enzyme extractant can be regarded as a degradation agent of the effective components of the flowers, and the mineral extractant can be regarded as an extraction carrier of the effective components of the flowers, and the enzyme extractant and the mineral extractant supplement each other and are matched with each other. Specifically, the enzyme extractant can modify and degrade macromolecular effective components such as protein in flowers, so that peptide chains of the macromolecular effective components are shortened, molecular weights of the macromolecular effective components are reduced, and other macromolecular effective components connected with the protein and the like can be degraded together, so that the effective components such as tea polyphenol, saccharides, tea protein, vitamins, caffeine and the like in the flowers are promoted to be smaller molecules, and the smaller molecules are more easily adsorbed by components such as montmorillonite, diatomite, sepiolite and the like containing a nano microsphere structure in the mineral substance extractant and then extracted.
Because the molecular weight of the protein is usually larger and is difficult to be absorbed by the mineral substance extractant, the content of the enzyme extractant is correspondingly increased under the condition of higher protein content in the flowers, which is beneficial to the full degradation and modification of the protein component by the enzyme extractant, further promotes the adsorption and extraction of the protein by the mineral substance extractant, improves the extraction efficiency, and vice versa.
Preferably, the flower material may be further subjected to a heating treatment and/or a ph adjustment treatment after being immersed in the extractant, to further enhance the degradation of the enzyme extractant and the adsorption of the mineral extractant. Wherein the heating treatment can be heating the extractant soaked in the flower material to 40-60 deg.C (such as 40 deg.C, 45 deg.C, 50 deg.C, 55 deg.C, 60 deg.C, etc.) for 1-2 hr; the pH value adjusting treatment may be performed by adding alkaline solution to adjust pH value of the extracting agent soaked in the flower material to be within 8-10 (such as 8, 8.5, 9, 9.5, 10, etc.).
S4 concentration: and sequentially heating and concentrating the extracting solution to obtain a concentrated solution containing the effective components of the flowers.
Specifically, the extract can be heated to 80-100 ℃ and kept for 1.5-3 hours to release the effective components of the flowers adsorbed by the minerals, and then concentrated to obtain the concentrated solution containing the effective components of the flowers. Wherein, the heating temperature of the extract can be 80 ℃, 85 ℃, 90 ℃, 95 ℃, 100 ℃ and the like, and the heating time can be 1.5h, 2h, 2.5h, 3h and the like, which is not limited in the application.
In practical application, the extract can be concentrated by vacuum concentration method to obtain the productThe concentrated solution containing the effective components of the flowers adopts a reduced pressure concentration method which comprises the following steps: concentrating the extractive solution at 60-75 deg.C under vacuum degree of 0.075-0.085MPa until the relative density of the extractive solution reaches 1.1-1.15g/cm3Filtering with 300 mesh vibrating screen to obtain concentrated solution containing effective components of flowers. In addition, other existing concentration methods can be adopted for concentration treatment, such as reverse osmosis concentration method and the like, which are not limited in the application and are not described herein again.
Further, a filtering step may be further included between the extraction at S3 and the concentration at S4, the filtering step preferably including: filtering the extractive solution containing effective components of tea flower with 70-90 mesh sieve tube or ceramic membrane. This filtration step enables the removal of macromolecular impurities from the liquid by filtration prior to concentration, thereby further improving the purity of the extract.
S5 purification: and purifying the concentrated solution by using a ceramic membrane and macroporous adsorption resin to obtain a purified solution.
Specifically, the concentrated solution can be filtered by adopting a ceramic membrane, the obtained filtrate passes through macroporous adsorption resin at the flow rate of 1-3BV/h, water, 60-70% ethanol, 3-5% alkali solution, 8-10% acid solution and acetone are respectively adopted for elution, the eluent directly passes through the macroporous adsorption resin at the flow rate of 0.1-0.5BV/h, the effluent liquid is collected, and the purified solution is obtained by concentration.
The ceramic membrane is densely distributed with micropores, the permeability is different according to the difference of the molecular diameters of substances permeating in a certain membrane aperture range, the pressure difference of two sides of the membrane is used as a driving force, the membrane is used as a filtering medium, and under the action of certain pressure, when concentrated solution flows through the surface of the membrane, only water, inorganic salt and small molecular substances are allowed to permeate through the membrane, and macromolecular substances such as suspended matters, glue, microorganisms and the like in water are prevented from passing through the membrane, so that the efficient and stable filtering and separating effect is achieved.
The macroporous adsorption resin is a macromolecular adsorption resin which does not contain exchange groups and has a macroporous structure, has a good macroporous net structure and a large specific surface area, can selectively adsorb organic matters in an aqueous solution through physics, and when the macroporous adsorption resin is eluted by water, 60-70% of ethanol, 3-5% of alkali solution, 8-10% of acid solution and acetone, effective components of protein, saccharides and the like in flowers flow out along with the macroporous adsorption resin, and then the purified solution is obtained by concentrating again.
It should be noted that, through this purification step, a substantial portion of the impurities in the concentrate can be filtered off, but some minerals may remain. However, even if a part of mineral residues still exist in the purified solution, the mineral extracting agent is not only non-toxic and harmless to human bodies, but also can provide abundant trace elements and increase the nutrient content of the flower extract.
S6 drying: and drying the purified solution to obtain a solid flower extract.
Specifically, the drying step preferably employs a lyophilization process, which includes a prefreezing process and a drying process.
The pre-freezing process comprises a temperature reduction process and a maintenance process, wherein the temperature reduction process is to reduce the temperature of the concentrated solution to a freezing point within 3 hours; the maintaining process is that the concentrated solution is maintained to be frozen at low temperature for 2 to 3 hours from the moment when the concentrated solution is reduced to the freezing point, and frozen matters of the concentrated solution of the flower extraction are obtained; and monitoring the central temperature of the concentrated solution in the process of the pre-freezing stage to obtain the temperature value of the eutectic point of the concentrated solution.
The drying process comprises the steps of firstly vacuumizing the frozen object obtained in the freezing step, and then heating and drying, wherein the heating process comprises low-temperature heating and high-temperature heating, and the low-temperature heating is to be maintained below the eutectic temperature of the frozen object so as to sublimate the moisture in the frozen object and obtain an anhydrous frozen object; the high-temperature heating is to rapidly warm the anhydrous frozen substance to room temperature and maintain the temperature until dried crystals of the flower extract, i.e., the flower extract in a solid state, are obtained.
In addition, the part of mineral substance extractant remained in the purified liquid can play a role in absorbing liquid heat, so that the crystallization of the purified liquid is promoted, the drying is accelerated, and the crystallization quality and the uniformity of crystals are improved.
