Description

Preparation method of fructus cannabis corn steep liquor
Technical Field
The invention belongs to the technical field of fructus cannabis corn beverages, and particularly relates to a preparation method of fructus cannabis corn steep liquor.
Background
The hemp seeds are rich in oil and fat, which are slightly different with the difference of planting climatic conditions, years and regions of the hemp plants. The hemp seed oil is a yellow green semitransparent oily liquid and has a special faint scent of hemp seeds. In the fatty acid composition of cannabis oil, the saturated fatty acid content is about 10%, the unsaturated fatty acid content is as high as approximately 90%, with the polyunsaturated fatty acid content ranging from 70-80%. The content of two polyunsaturated essential fatty acids, linoleic acid (LA, 18:2n-6) and alpha-linolenic acid (ALA, 18:3n-3) is typically 50-70% and 15-25%. The two polyunsaturated fatty acids have anti-inflammatory, antithrombotic, antiarrhythmic, and hypolipidemic effects. The ratio of n-6 to n-3 fatty acids in hemp oil is about 3:1, and this balance is unique among common vegetable oils and is most beneficial to human health. The cannabis oil is rich in tocopherol and chlorophyll, wherein the content of gamma-tocopherol is highest, and the cannabis oil has a strong antioxidation effect in grease. Hemp oil is widely used in baking and cooking and is an important raw material for cheese, salad dressing, margarine, cake, dessert, and the like.

In addition, the content of selenium in the corn is 8-10 times higher than that of common corn, and modern medical research shows that the selenium has the effects of enhancing immunity, preventing diabetes and cardiovascular and cerebrovascular diseases, preventing and treating liver diseases, protecting liver and the like. However, the direct gelatinization of the normal rice milk after the crushing easily causes that the starch is not easy to be completely gelatinized and generate precipitates. Meanwhile, the corn steep liquor is easy to deteriorate

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example 1
A preparation method of fructus cannabis corn steep liquor comprises the following steps:
(1) pulverizing semen Maydis, adding fructus Cannabis powder, adding water, stirring and mixing;
pouring the rogued corns into a soaking tank, and adding water with the temperature of 30-35 ℃ until the corns are completely soaked for 24-48 hours; crushing the soaked corn to form corn flour; screening the hemp seeds to remove impurities, mechanically squeezing the hemp seeds at normal temperature, and separating oil and hemp seed meal; removing redundant grease from the fructus cannabis seed meal by supercritical extraction to obtain dry meal; respectively weighing 90-100 parts of hemp seed dry meal and corn flour according to parts by weight; carrying out extrusion and puffing treatment after mixing, adding 0.01 part of nano zinc oxide, stirring again until the raw materials are uniformly mixed, putting the uniformly stirred raw materials into a flour mill, grinding, adding water and stirring uniformly;
the method has the advantages that the method can be more beneficial to the separation of the components in the hemp seed dry meal and the corn flour by adopting the extrusion and expansion treatment in advance, and the food materials in the prior art are mostly placed at the tail sound of the manufacturing step after the expansion treatment, so that the stability of the nutrient components is ensured, and the loss of the compounds is avoided. In the invention, the retention of a small part of nutrient substances is abandoned, so that the hemp seed powder, the corn flour and the corn flour can be more uniformly mixed in the preparation process of the raw materials, and the components separated out after the hemp seed cypress is puffed can be more uniformly distributed in the slurry. Meanwhile, the corn is selected as the main material, more on the basis of better elasticity and low cooking loss rate of the corn, and tests show that the mixed taste of the hemp seed powder and the corn flour is better than that of the corn steep liquor without the hemp component. According to microscopic analysis, the bonding effect of the puffed hemp seeds and the corn flour is better. Meanwhile, because the bacteriostatic components such as linoleic acid, linolenic acid and the like in the hemp can effectively prolong the shelf life of the corn steep liquor, the characteristics and the mechanism thereof are not disclosed in the prior art. Therefore, it is not reasonable and can not be easily conceived by those skilled in the art to the technical contents, thereby making the present invention sufficiently inventive.
(2) Adding protease and high-temperature amylase into the mixture for carrying out first enzymolysis; adding alkaline protease according to the mass portion, adjusting the pH value to 9-10 at the temperature of 60 +/-2 ℃, and carrying out first enzymolysis under the conditions that the enzyme adding amount is 3-5% of the weight of the hemp seeds, the material-liquid ratio is 1:5 and the time is 2-4 h;
(3) adding cellulase and papain into the mixture for second enzymolysis; after reaching the time of the first enzymolysis, carrying out high-temperature enzyme deactivation, cooling, adjusting the pH value to 5.5, adding papain, carrying out second enzymolysis at the temperature of 60-65 ℃ and the enzyme addition amount of 0.5 percent of the weight of the hemp seeds, after 3 hours, carrying out high-temperature enzyme deactivation, cooling, centrifuging, extracting supernatant, carrying out microwave detoxification, carrying out superheated steam treatment, and then drying by hot air to prepare hemp corn pulp powder;
the alkaline protease is solid alkaline protease, and the preparation steps of the alkaline protease are as follows: firstly, preparing 20ml of agarose-phosphoric acid solution with the mass fraction of 4% by using phosphoric acid solution with the pH value of 6; boiling under microwave condition for more than 10min, cooling to room temperature, adding 70g/L alkaline protease solution 3ml, cooling to 20 deg.C to obtain gel, cutting into pieces of 2cm × 2cm, and storing at 8 deg.C as solid alkaline protease. Screening out the agarose block after the first enzymolysis, wherein the papain is solid papain during the second enzymolysis, and the preparation steps of the papain are as follows: firstly, preparing 20ml of agarose-phosphoric acid solution with the mass fraction of 4% by using phosphoric acid solution with the pH value of 6; boiling for more than 10min under microwave condition, cooling to room temperature, adding 90g/L cellulase solution 2ml, cooling to 15 deg.C to form gel, cutting into pieces of 2cm x 2cm, and storing at 10 deg.C as immobilized papain. After the solid material is cut into 2cm x 2cm small blocks, 1,2,3,4, 5-pentadiol solution with the mass fraction of 0.10% is added into alkaline protease, cellulase or papain as a protective agent before low-temperature storage, and the mixture is soaked for more than 10 min.
The invention provides a secondary protease hydrolysis method, which hydrolyzes the hemp protein into small molecular peptides which are easier to be absorbed by human bodies and avoid anaphylactic reaction. Meanwhile, the alkaline protease and the papain provided by the invention carry out enzymolysis at the temperature of about 60 ℃, the traditional enzymolysis means mostly directly adopts a liquid enzyme preparation for enzymolysis, namely a protease solution is prepared and mixed to enter protein for liquid enzymolysis, the enzymolysis speed of the protein has obvious speed reduction fluctuation from 40 ℃ to 70 ℃, because the activity of the alkaline protease is obviously reduced after the temperature exceeds 60 ℃, the enzymolysis process is at a lower proper temperature such as 40-50 ℃ in order to ensure the enzyme activity, but once the temperature is too low, the performance of the hemp protein tends to be stable and even solidified, and the enzymolysis reaction speed is reduced along with the reduction of the temperature, which is not beneficial to enzymolysis; if the temperature is too high, the protein has allergic reaction and also has solid property, thereby influencing the effective storage of the protein, reducing the content of the protein and reducing the health care function. Therefore, for liquid enzyme preparations, the reaction conditions are harsh, and the inactivation failure is easily caused by the influence of factors such as high temperature, acid and alkali, and the like, and the free enzyme is difficult to recycle in the reaction system, so the application in large-scale industrial production is limited. In addition, in the catalysis process, the protease possibly has a cross-linking effect with the enzyme under the action of carbodiimide, so that the enzyme activity of the protease is limited, and the catalytic hydrolysis of a substrate is influenced. Therefore, the invention provides that the protease is solidified, the molecule of the protease is locked in the solidified structure, so that the active center of the protease is protected by the heat-insulating layer, the stability to temperature change is improved, and the protease molecule can be positioned to avoid the crosslinking effect.
Therefore, the invention provides a solid stating step for controlling protease: firstly, preparing an agarose-phosphoric acid solution by using a phosphoric acid solution with a pH value of 6; boiling under microwave condition, cooling to room temperature, adding alkaline protease solution, cooling to gel, cutting into pieces of 2cm × 2cm, and storing at low temperature. The alkaline protease of the present invention is immobilized in agarose gel blocks.
After the first enzymolysis is finished, the agarose block needs to be screened out, and then the second enzymolysis is carried out. The papain in the secondary enzymolysis process is solidified by adopting the method, which comprises the following steps: firstly, preparing an agarose-phosphoric acid solution by using a phosphoric acid solution with a pH value of 6; boiling under microwave condition, cooling to room temperature, adding alkaline protease solution, cooling to 10-14 deg.C to form gel, cutting into pieces of 2cm × 2cm, and storing at low temperature. The papain is solidified into the agarose gel block.
Papain is called papain for short, and is also called papain. Is a pure natural biological enzyme product which is refined by using milk in immature papaya fruits and adopting the modern bioengineering technology. It is a sulfhydryl (-SH) containing endopeptidase, has the activity of proteinase and esterase, has extensive specificity, and has strong hydrolytic power for animal and plant protein, polypeptide, ester and amide, at the same time, it also has synthesis function, and can synthesize protein hydrolysate into protein-like product.
Agarose agar, abbreviated as AG, added for the purposes of the present invention is an uncharged neutral constituent of agar and is also known as agarosine or Agarose. The chemical structure of the agar sugar is formed by long chains formed by alternately connecting 1, 3-linked beta-D-galactose and 1, 4-linked 3, 6-lacto-L-galactose. Can be used in the food industry for the production of: soft candy, shaped soft candy, aquatic product, canned meat, fruit juice beverage, fruit pulp beverage, rice wine beverage, dairy beverage, essence, and dairy cake. The addition of the agarose can solidify the protease, and residues of the protease can be decomposed in subsequent processing without residues, so that the processing is favorable for edible processing.
In the case of sufficient moisture, the steam treatment results in an increase in the degree of crosslinking of amylose and amylopectin. This makes the starch more difficult to contact with the amylolytic enzyme, thereby affecting its decomposition efficiency and further enhancing the mouthfeel of the slurry. The method for increasing the mouthfeel of the slurry by carrying out superheated steam treatment on the puffed powder is also a technical characteristic which is not disclosed by the technical personnel in the field, and compared with the similar technology, the method can further help to greatly improve the product quality.
(4) Boiling the mixture, cooling and filtering; adding water of a certain quality into the cannabis corn steep liquor powder, boiling for 2 hours, and standing for 0.5 hour to obtain cannabis corn steep liquor base liquid;
(5) adding hemp seed oil; adding the separated oil into a hemp corn steep liquor base liquid; executing the step (6);
(6) homogenizing; homogenizing the base liquid, and adding food additive; executing the step (7);
(7) sterilizing at high temperature; adding water into several pages to dilute the concentration of the base solution to form fructus cannabis corn steep liquor, and sterilizing at high temperature;
(8) and (4) filling, namely filling the cannabis corn steep liquor to form the cannabis corn steep liquor product.
Comparative example 1:
the technical scheme is the same as that of the embodiment 1, except that the extrusion puffing comprises the following steps:
after the hemp seed meal and the corn are crushed, adjusting the water content of the material, the puffing temperature and the screw rotating speed to carry out double-screw extrusion puffing treatment, and optimizing by a response surface method to obtain the conditions with the highest content of the soluble dietary fiber:
the content of soluble dietary fiber is 16-0.3X-0.2Y +0.15Z-0.57XY +0.2XZ-0.34YZ-1.1X2-0.75Y2-1.5Z2
Wherein X is the moisture of the material, Y is the puffing temperature, and Z is the screw rotation speed.
CO with the pressure of 11MP is added in the process of the double-screw extrusion and expansion treatment2As a foaming agent, the hemp seed meal and corn cell structures are destroyed, so that the hemp oil is fully exposed, and the fenamic acid compound is fully overflowed. CO under a certain pressure2The hemp seed meal is added to the extrusion puffing step instead of water vapor for pre-dissolving and wall breaking, so that the lipase activity can be effectively passivated, compared with the traditional extrusion puffing step, the temperature of the extrusion puffing is reduced, the thermosensitive components in the hemp seed meal are well preserved, and the nutritional value is further improved. The technical characteristic is not disclosed in the extrusion and the expansion of the hemp seed meal, and the aim is to reduce the expansion temperature and inactivate the lipase activity, thereby improving the nutritional value. This is a technical solution that is not available to the skilled person through the prior art, and is fully inventive.
Comparative example 2:
the method is the same as the technical scheme of the embodiment 1, and is different from the method in that the nano zinc oxide is prepared by drying and dehydrating at the temperature of 60 ℃ by using sodium hydroxide as a precipitator, carboxymethyl chitosan as a stabilizer and zinc oxide as a zinc source. The invention creatively adds trace nano zinc oxide, under the condition of ensuring food to be nontoxic, the ammonia matrix in the nano zinc oxide is protonated to ensure that the nano zinc oxide is positively charged and is easy to interact with bacteria with negative electricity on the surface, and the bacterial metabolism is influenced, so that the bacteria are inhibited. Meanwhile, the chitosan film layer of the nano zinc oxide has the characteristic of water resistance, has selective permeability to gas, can increase the penetration resistance of air, can reduce the oxygen content in the noodle structure, reduces the water loss, and plays a role in preservation and corrosion prevention. The application characteristic of the nano zinc oxide in the invention is taken as the second distinguishing technical characteristic of the invention, and in the preparation process of the slurry, no technical personnel in the field propose the scheme to improve the freshness of the product or other foods. This is also a solution that is not readily available to the skilled person and is therefore fully inventive.
Comparative example 3:
the technical scheme is the same as that of the embodiment 1, except that azodicarbonamide with the concentration of not higher than 10mg/kg is added in the boiling process. Azodicarbonamide has begun to be widely used abroad as an improver and has passed the approval certification of WHO and FDA. The azodicarbonamide has little effect on the hemp seed powder or corn flour, but when the azodicarbonamide is stirred with water, active oxygen is quickly released, hydrogen sulfide in hemp protein is oxidized into disulfide bonds, and protein chains are mutually connected to form a dough net structure, so that the physical property and the tissue structure of the slurry are improved. The third technical characteristic of the invention is that the combination of azodicarbonamide and nano-zinc oxide is used, in the process of cooling, the film structure formed by the nano-zinc oxide can further lock the azodicarbonamide and active oxygen released by the azodicarbonamide, so that the effect of the azodicarbonamide is further improved, the taste and quality of the corn steep liquor are improved while the nano-zinc oxide is kept fresh, and the effect of killing two birds with one stone is achieved. It has solved the not good problem of traditional corn steep liquor taste. Since the use mode is not disclosed in the prior art, the technical effect of improving the quality of the hemp corn steep liquor by using the characteristic of combining azodicarbonamide and nano zinc oxide after doping the nano zinc oxide is not reasonable or impossible for a person skilled in the art. This technical feature can thus embody the inventive step of the present invention.
Comparative example 4:
the method is the same as the technical scheme of the embodiment 1, and is different from the method in that the filling process is in a nitrogen environment. In the hot air drying, circulating air with the speed of 15-17 m/s is used for drying.
