Description
Technical Field
The invention relates to the technical field of cigarette essence and spice, in particular to a purification method of bead blasting essential oil.
Background
In order to improve the quality and the use effect of the bead blasting essential oil, the olive oil is often used as essential oil base oil. The olive oil contains various vitamins and mineral elements such as calcium, phosphorus, iron, potassium, selenium and the like, and is also rich in various unsaturated, monounsaturated and saturated fatty acids and phospholipids. Wherein, the squalene with the highest oil content has the function of oxidation resistance, but once oxidized, the squalene plays the role of an oxygen-assisting agent. In addition, olive oil contains considerable amount of tocopherol, phytosterol, carotenoid and glycolipid compound, wherein chlorophyll is a photosensitizer and can promote the oxidation of oil under the condition of light. In general, many cyclic olefins exist in olive oil, wherein hydrocarbon olefins containing carbon-carbon double bonds (C = C) are very unstable at normal temperature and pressure, and are easily oxidized with oxygen in the air to form high molecular sticky substances, so that the color of the oil product is gradually deepened.
The quality of the olive oil has certain influence on the process of dropping the exploded beads, and if fine bubbles and precipitated impurities exist in the olive oil, the problems of solid beads, eccentric beads, special-shaped beads and the like can be generated in the dropping process, so that the yield of the exploded beads is influenced. Due to the oxidation of olive oil, the olive oil is gradually viscous and a small amount of precipitate appears, so that the olive oil needs to be purified to remove substances such as oxidation impurities, micro bubbles and other impurities, so as to ensure the uniformity of the bead blasting essential oil and the stability of bead blasting dripping forming. Chinese patent CN201811172101.1 discloses a method for efficiently removing wax in olive oil by using a pulsed electric field and application thereof.

(10) drying natural zeolite, crushing the dried natural zeolite into 250-300 meshes, roasting the natural zeolite at 350-450 ℃ for 1.5-2 hours to obtain roasted zeolite, and enabling the zeolite to become loose and porous sponge bodies through roasting treatment so as to improve the cation exchange and adsorption capacity of the zeolite;

(12) and taking out the zeolite subjected to oscillation treatment, standing for more than 12h, washing with water until the pH value is 6-7, and drying at 60-70 ℃ for more than 12h to obtain the cation-loaded modified zeolite.
The modified attapulgite used in the invention is prepared by the following method:
(20) crushing attapulgite to 300-350 meshes, and placing the crushed attapulgite in dilute sulfuric acid with the concentration of 0.8-1.3 mol/L for acidification treatment for 3-5 hours; preferably, the solid-to-liquid ratio of the attapulgite to the dilute sulfuric acid is 1: 10-1: 15.
(21) Washing the acidified attapulgite with water until the pH value is 6-7, roasting at 250-260 ℃ for 2-3 h, cooling, and storing in a dryer.
Natural attapulgite belongs to hydrous magnesium aluminum silicate fibrous clay minerals, and has special mineral morphology and crystal structure, most of the states are that only four of five octahedral positions are occupied, and the vacancy positions are in trans positions. The special crystal structure and the stacking mode form a large number of pore channel structures, the needle-rod-shaped and fibrous crystal particles form the interstitial holes in the aggregate, and the pore diameter range covers micropores, mesopores and macropores.
The modified attapulgite obtained by extrusion crushing, acid treatment, water washing neutralization and medium-temperature roasting of the material bed enables symbiotic cement in the minerals to be dissolved out, and continuous crystal beams of the attapulgite are dispersed into a fluffy single crystal structure due to the action of acid etching. Meanwhile, the hair-shaped crystal substances converted from the montmorillonite to the attapulgite by the acid treatment are hydrolyzed to form more recrystallized attapulgite crystals, namely more fine microneedle rod-shaped and fibrous crystals, and the specific surface area is further improved. The acid reaction not only increases the pore size and the nanopore structure, but also causes the change of the property of the surface functional group, and the octahedral cation H+For positive ion Mg2+，Al3+，Fe3+Displacement from edge to center in sequence until completely substituted, and H+Not completely occupying the octahedral sites of the cations, but rather more of the O anions co-ordinating with the original-The combination forms silanol alkyl Si-OH, and the Si-OH functional group can well adsorb organic matters. In addition, R-OH structures generated by hydrolysis of Si-O broken bonds and Al-O, Mg-O broken bonds also form a large amount of L-acid-base active centers and B-acid-base active centers, and in the adsorption and catalysis in the grease decoloring process, the active sites are the positions where the adsorption and catalysis of the attapulgite occur, and are one of the important conditions that the modified attapulgite has excellent adsorption performance. The attapulgite is acidized by dilute sulfuric acid, and then is activated at a medium temperature of 250-260 ℃, so that fiber bundles of the attapulgite are depolymerized, the pore volume of the attapulgite is improved, the surface area of the attapulgite is increased, pores and broken bonds of the attapulgite are more exposed, and the adsorbability and the ion exchange capacity of the attapulgite are improved.
The natural zeolite has SiO as basic structure4Silicon-oxygen tetrahedron and AlO4Aluminum tetrahedronThe three-dimensional porous structure is characterized in that the three-dimensional porous structure and the three-dimensional porous structure are connected through oxygen bridges to form a cavity with a three-dimensional net structure, the cavities are communicated with each other through various micro pore channels to form a criss-cross spatial network microporous structure, and the micropores are uniform in size, large in specific surface area and high in adsorption performance. The negative charge center on the anion lattice of the zeolite is not overlapped with the positive charge center of the balancing cation in space, so that the zeolite has larger electrostatic attraction, simultaneously has large dispersion force, has selective adsorption effect on polar, unsaturated and easily polarized molecules and has poorer adsorption performance on hydrophobic organic matters. The adsorption capacity of the modified zeolite to hydrophobic organic matters is greatly improved by modifying the surface of the zeolite and introducing nonpolar hydrophobic groups. Zeolites are capable of strong interactions with unsaturated compounds, i.e., molecules of organic compounds that can be polarized, containing double bonds, triple bonds, etc.
The invention has the obvious advantages that the modified zeolite and the modified attapulgite are compounded to be used as a primary adsorption and filtration material, and the purification treatment of the bead blasting essential oil can be realized at room temperature. In the existing technology, when bentonite, clay and other adsorbents are used for carrying out decolorization and degumming treatment, the oil needs to be heated to 80-110 ℃ so as to better meet the adsorption generated in the decolorization process of the oil and the energy exchange condition accompanied by the action in the reaction process. The transmittance of the olive oil can be obviously increased (the transmittance at the wavelength of 500nm is improved by 47.9 percent, and the transmittance at the wavelength of 400nm is improved by 70.3 percent) by the purification method.
The invention adopts the mixed adsorption material of modified zeolite and modified attapulgite to carry out multi-point adsorption, competitive adsorption and ion exchange adsorption on easily oxidizable substances such as free fatty acid, phospholipid, carotenoid, chlorophyll, tocopherol, cycloolefins and the like in the bead blasting essential oil so as to remove the easily oxidizable substances in the bead blasting essential oil in advance and prevent the easily oxidizable substances from being gradually oxidized in the bead blasting essential oil to generate insoluble impurities.
The purification method of the exploded bead essential oil comprises the steps of firstly, carrying out primary adsorption and filtration impurity removal treatment on the exploded bead essential oil through an adsorption material, and removing substances such as free fatty acid, wax and the like in the exploded bead essential oil through the adsorption material; then removing fine particle insoluble impurities in the bead blasting essential oil through a plate frame filter and a ceramic membrane device in sequence, and further purifying the bead blasting essential oil; finally, removing micro-bubble impurities in the bead blasting essential oil through vacuum degassing. According to the purification method of the bead blasting essential oil, the bead blasting essential oil is purified through four-step impurity removal treatment, so that easily-oxidizable substances, insoluble impurities and micro bubbles in the bead blasting essential oil are removed, the bead blasting essential oil is uniform and stable in quality, the oil quality of the bead blasting essential oil is improved, the bead blasting dripping forming effect is improved, and the bead blasting forming rate is further improved.
