Description

Invenţia se referă la industria vinicolă, şi anume la un procedeu de determinare a compuşilor volatili în vinul alb. The invention relates to the wine industry, namely to a process for determining volatile compounds in white wine.

Înainte de detectarea compuşilor volatili prin cromatografie şi spectrometrie de masă (GC-MS) este necesar să se efectueze extracţia corespunzătoare a acestora. Before detecting volatile compounds by chromatography and mass spectrometry (GC-MS), it is necessary to perform their appropriate extraction.

Este cunoscut procedeul discontinuu de extracţie lichid-lichid a compuşilor volatili din vin cu un solvent organic, care prevede răcirea a 100 ml de vin cu adăugarea standardelor etalon de 0,05 ml de soluţie alcoolică echivalentul a 29 µg de 3-octanol şi a 23 µg de 4-nonanol; ulterior se efectuează adăugarea solventului diclormetan în cantitate de 40 ml şi amestecarea la viteza de 350 rot/min timp de 20 min; centrifugarea soluţiei obţinute la viteza de 8500 rot/min timp de 10 min la temperatura de 5°C cu recuperarea fazei organice şi deshidratarea acesteia cu sulfat de sodiu şi concentrarea până la un volum final de 0,1 ml prin distilare în vid şi injectarea probei la GC-MS [1]. The discontinuous liquid-liquid extraction process of volatile compounds from wine with an organic solvent is known, which involves cooling 100 ml of wine with the addition of 0.05 ml of standard alcoholic solution equivalent to 29 µg of 3-octanol and 23 µg of 4-nonanol; subsequently, the dichloromethane solvent is added in an amount of 40 ml and mixed at a speed of 350 rpm for 20 min; centrifugation of the solution obtained at a speed of 8500 rpm for 10 min at a temperature of 5°C with recovery of the organic phase and its dehydration with sodium sulfate and concentration to a final volume of 0.1 ml by vacuum distillation and injection of the sample into GC-MS [1].

Dezavantajul acestui procedeu constă în aceea că permite determinarea numai a 26 de compuşi volatili ai vinului, procesul este îndelungat, necesită un volum mare de reactivi şi nu este posibilă automatizarea lui. The disadvantage of this process is that it allows the determination of only 26 volatile compounds in wine, the process is long, requires a large volume of reagents and cannot be automated.

De asemenea, este cunoscut procedeul discontinuu de extracţie lichid-lichid a compuşilor volatili din vin, în care 25 ml de vin se introduc într-un cilindru cu dop şlefuit, se adaugă 6…8 g de NaCl cristalin, se amestecă bine, apoi se adaugă 2 ml de ester dietilic. Se efectuează extragerea timp de 10…15 min, apoi se lasă până la stratificare. Pentru analiză se foloseşte stratul superior [2]. Also, the discontinuous process of liquid-liquid extraction of volatile compounds from wine is known, in which 25 ml of wine is placed in a cylinder with a ground stopper, 6…8 g of crystalline NaCl are added, mixed well, then 2 ml of diethyl ester is added. The extraction is carried out for 10…15 min, then left until stratification. The upper layer is used for analysis [2].

Dezavantajul acestui procedeu constă în aceea că detectarea compuşilor volatili se efectuează la un gaz-cromatograf, procedeul poate fi considerat mai mult calitativ decât cantitativ, se utilizează pentru compararea cu aromograma aromatizatorului sintetic-etalon, necesită soluţii de aromatizatori sintetici-etalon. The disadvantage of this process is that the detection of volatile compounds is performed on a gas chromatograph, the process can be considered more qualitative than quantitative, it is used for comparison with the aromogram of the standard synthetic flavoring, it requires solutions of standard synthetic flavorings.

Mai este cunoscut procedeul de microextracţie pe fază solidă în baza SBSE (Stir Bar Sorptive Extraction), care prevede prelevarea unei probe de vin în volum de 5 ml şi trecerea lui într-un balon, amplasarea directă în vin a unei tije de extracţie, care reprezintă o tija din sticlă utilizată ca agitator magnetic acoperită cu un strat de adsorbţie constituit din polidimetilsiloxan; balonul se închide şi este supus agitării magnetice timp de 1 h; ulterior tija se extrage cu un cleşte, se clăteşte cu apă distilată, se plasează într-un tub de sticlă pentru desorbţie termică care este cuplat cu cromatograful GC-MS [3]. The solid-phase microextraction process based on SBSE (Stir Bar Sorptive Extraction) is also known, which involves taking a 5 ml wine sample and transferring it into a flask, placing an extraction rod directly into the wine, which is a glass rod used as a magnetic stirrer covered with an adsorption layer made of polydimethylsiloxane; the flask is closed and subjected to magnetic stirring for 1 h; subsequently, the rod is extracted with forceps, rinsed with distilled water, and placed in a glass tube for thermal desorption that is coupled to the GC-MS chromatograph [3].

Dezavantajele acestui procedeu constau în aceea că sunt necesare utilaje suplimentare pentru desorbţia termică, permite determinarea numai a 50 de compuşi volatili ai vinului, precum şi incapacitatea de extragere deplină a constituenţilor volatili din cauza că extracţia este întotdeauna limitată de coeficienţii fazei de distribuţie a substanţelor extractibile şi de raportul dintre volumele fazelor soluţiei şi adsorbantului într-un sistem de echilibru. The disadvantages of this process are that additional equipment is required for thermal desorption, it allows the determination of only 50 volatile compounds of wine, as well as the inability to fully extract volatile constituents because the extraction is always limited by the phase distribution coefficients of the extractable substances and the ratio between the volumes of the solution and adsorbent phases in an equilibrium system.

Cea mai apropiată soluţie tehnică de prezenta invenţie este procedeul de extracţie pe fază solidă în concentrare dinamică, conform căruia soluţia de probă este trecută printr-un cartuş de extracţie, care are forma unei seringi, în interiorul căreia se află masa adsorbantă. De regulă, trecerea (eluţia) prin cartuş a unui volum de lichid (probă sau solvent) este favorizată de crearea unui vid la capătul cartuşului. În calitate de adsorbant se utilizează polistiren suprareticulat. După aceasta se efectuează spălarea materialului cu un solvent adecvat pentru îndepărtarea eventualilor contaminanţi ai adsorbantului; uscarea materialului adsorbant, care se realizează prin trecerea continuă a unui curent de aer prin cartuş sau prin aplicarea în condiţia unei suprapresiuni a unui gaz inert; acomodarea materialului adsorbant cu solventul probei prin trecerea unui volum mic din acesta prin masa adsorbantă; urmează extracţia propriu-zisă, care constă în trecerea unui volum bine stabilit de probă peste materialul adsorbant; apoi spălarea adsorbantului, această a doua spălare se realizează în scopul îndepărtării efectelor de matrice, care pot apărea datorită unor fenomene de reţinere neselectivă, se foloseşte de obicei solventul probei. Nu se vor utiliza solvenţi care să permită solubilizarea şi desorbţia compuşilor interesaţi. Se continuă cu uscarea adsorbantului, care se realizează prin intermediul unui curent de aer sau a unui gaz inert; desorbţia, etapa constă în solubilizarea compuşilor interesaţi şi antrenarea lor din interiorul matricei solide în care au fost anterior reţinuţi, prin intermediul unui solvent adecvat. În cazul în care concentraţia analitului după desorbţie se situează sub limita de detecţie a sistemului cromatografic, este absolut necesară o etapă de preconcentrare. Preconcentrarea se realizează în general prin evaporarea selectivă a solventului într-un flux moderat de gaz inert [4]. The closest technical solution to the present invention is the solid phase extraction process in dynamic concentration, according to which the sample solution is passed through an extraction cartridge, which has the shape of a syringe, inside which the adsorbent mass is located. As a rule, the passage (elution) through the cartridge of a volume of liquid (sample or solvent) is favored by creating a vacuum at the end of the cartridge. As an adsorbent, crosslinked polystyrene is used. After this, the material is washed with an appropriate solvent to remove any contaminants of the adsorbent; drying of the adsorbent material, which is achieved by continuously passing an air current through the cartridge or by applying an inert gas under overpressure; accommodation of the adsorbent material with the sample solvent by passing a small volume of it through the adsorbent mass; the extraction itself follows, which consists in passing a well-established volume of sample over the adsorbent material; then washing the adsorbent, this second washing is carried out in order to remove matrix effects, which may occur due to non-selective retention phenomena, the sample solvent is usually used. Solvents that allow the solubilization and desorption of the compounds of interest will not be used. The adsorbent is continued with drying, which is carried out by means of a current of air or an inert gas; desorption, the stage consists of solubilizing the compounds of interest and entraining them from inside the solid matrix in which they were previously retained, by means of an appropriate solvent. If the analyte concentration after desorption is below the detection limit of the chromatographic system, a preconcentration stage is absolutely necessary. Preconcentration is generally carried out by selective evaporation of the solvent in a moderate flow of inert gas [4].

Dezavantajul acestui procedeu constă în efectul de adsorbţie scăzut pentru compuşii volatili din vin. The disadvantage of this process is the low adsorption effect for volatile compounds in wine.

Problema pe care o rezolvă prezenta invenţie este pregătirea prealabilă a adsorbantului solid din polistiren suprareticulat, în scopul majorării efectului de adsorbţie a compuşilor volatili din vin şi reducerii procedurii de pregătire a probelor. The problem solved by the present invention is the preliminary preparation of the solid adsorbent made of supercrosslinked polystyrene, in order to increase the adsorption effect of volatile compounds in wine and reduce the sample preparation procedure.

Procedeul, conform invenţiei, include pregătirea probei de vin prin adăugarea sulfatului de amoniu şi 2-heptanolului, pregătirea prealabilă a unui adsorbant solid din polistiren suprareticulat, amplasat într-un cartuş, prin tratarea succesivă a acestuia cu clorură de metilen şi etanol, spălarea cu apă distilată şi suflarea cu un jet de aer; adsorbţia compuşilor volatili la trecerea probei prin cartuş sub vid şi spălarea adsorbantului cu apă distilată; desorbţia compuşilor volatili la trecerea prin adsorbant a unui solvent, format din acetat de etil şi clorură de metilen în proporţie de 1:1 după volum, cu obţinerea unui eluat, tratarea acestuia cu sulfat de sodiu anhidru, evaporarea până la obţinerea unui concentrat în cantitate de 0,5 ml şi determinarea compuşilor volatili prin cromatografie şi spectrometrie de masă. The process, according to the invention, includes the preparation of the wine sample by adding ammonium sulfate and 2-heptanol, the preliminary preparation of a solid adsorbent made of supercrosslinked polystyrene, placed in a cartridge, by successively treating it with methylene chloride and ethanol, washing with distilled water and blowing with an air jet; adsorption of volatile compounds when the sample passes through the cartridge under vacuum and washing the adsorbent with distilled water; desorption of volatile compounds when a solvent, consisting of ethyl acetate and methylene chloride in a ratio of 1:1 by volume, passes through the adsorbent, obtaining an eluate, treating it with anhydrous sodium sulfate, evaporation until obtaining a concentrate in an amount of 0.5 ml and determination of volatile compounds by chromatography and mass spectrometry.

Rezultatul constă în majorarea capacităţii de adsorbţie şi a numărului de compuşi determinaţi. The result is an increase in adsorption capacity and the number of determined compounds.

Utilizarea la pregătirea fazei solide a acetatului de etil, clorurii de metilen şi etanolului asigură o gonflare eficace şi majorarea capacităţii de adsorbţie a compuşilor volatili. Datorită acestui fapt numărul de compuşi aromatici, determinaţi la cromatograful GC-MS, este de 129 şi este de circa 2 ori mai mare în raport cu procedeele cunoscute. The use of ethyl acetate, methylene chloride and ethanol in the preparation of the solid phase ensures effective swelling and increases the adsorption capacity of volatile compounds. Due to this fact, the number of aromatic compounds determined by GC-MS is 129 and is about 2 times higher compared to known processes.

Folosirea apei distilate pentru spălarea cartuşului încărcat asigură o înlăturare mai eficace a compuşilor chimici de altă natură, spre exemplu a compuşilor fenolici, este inertă faţă de substanţele aromatice adsorbite şi nu modifică natura lor. Using distilled water to wash the loaded cartridge ensures a more effective removal of chemical compounds of other nature, for example phenolic compounds, is inert towards the adsorbed aromatic substances and does not modify their nature.

Utilizarea în calitate de soluţie standard intern a 2-heptanolului permite determinarea cu o mare precizie a concentraţiei substanţelor volatile identificate, iar utilizarea sulfatului de amoniu asigură o separare bună a alcoolilor volatili din vin ce participă la formarea aromei. The use of 2-heptanol as an internal standard solution allows for the high-precision determination of the concentration of identified volatile substances, and the use of ammonium sulfate ensures good separation of volatile alcohols from wine that participate in the formation of aroma.

Utilizarea acetatului de etil şi clorurii de metilen în amestecul utilizat pentru eluţia substanţelor aromatice asigură practic desorbţia totală a acestora de pe suprafaţa fazei solide. The use of ethyl acetate and methylene chloride in the mixture used for eluting aromatic substances ensures practically their total desorption from the surface of the solid phase.

Astfel, utilizarea compuşilor menţionaţi, cum ar fi clorura de metilen, etanolul şi apa distilată la pregătirea prealabilă a suprafeţei cartuşului, precum şi a sulfatului de amoniu dizolvat în vinul investigat permit o separare mai bună a alcoolilor volatili. Utilizarea soluţiei de 2-heptanol în calitate de soluţie standard intern şi a clorurii de metil în amestecul folosit pentru desorbţia substanţelor aromatice permite obţinerea unor noi rezultate, care constă în majorarea de circa 2 ori a numărului de compuşi volatili identificaţi în vinurile albe supuse investigării la cromatograful GC-MS. Thus, the use of the mentioned compounds, such as methylene chloride, ethanol and distilled water in the preliminary preparation of the cartridge surface, as well as ammonium sulfate dissolved in the investigated wine, allow a better separation of volatile alcohols. The use of 2-heptanol solution as an internal standard solution and methyl chloride in the mixture used for the desorption of aromatic substances allows obtaining new results, which consists in increasing by about 2 times the number of volatile compounds identified in the white wines subjected to investigation by GC-MS chromatograph.

Procedeul propus se efectuează în felul următor. The proposed procedure is carried out as follows.

Cartuşul cu faza solidă, alcătuită din polistiren suprareticulat, de exemplu tip „DIAPAK P”, Federaţia Rusă în cantitate de 3...6 ml, este tratat succesiv cu 5 ml de clorură de metilen, apoi cu 5 ml de etanol şi la sfârşit cu 10 ml de apă distilată. După care, mostra de vin preconizată pentru investigare în cantitate de 50 ml, în care se adaugă 10 g de sulfat de amoniu şi 0,5 ml soluţie de 2-heptanol cu concentraţia de 98%, este trecută sub vid prin cartuşul pregătit cu o viteză de 0,5 ml/min. După finalizarea procesului cartuşul este spălat cu apă distilată în cantitate de 10 ml şi suflat cu un jet de aer timp de 5 min. Desorbţia compuşilor volatili de pe suprafaţa cartuşului se efectuează cu un amestec de acetat de etil şi clorură de metilen în proporţie de 1:1 (după volum) în cantitate de 4 ml. Extractul obţinut este tratat cu sulfat de sodiu anhidru, pentru asanarea acestuia şi legarea compuşilor fenolici, şi concentrat prin evaporare până la obţinerea unui volum de 0,5 ml. După pregătirea respectivă extractul este injectat în cromatograful GC-MS. The solid phase cartridge, made of supercrosslinked polystyrene, for example type "DIAPAK P", Russian Federation in the amount of 3...6 ml, is treated successively with 5 ml of methylene chloride, then with 5 ml of ethanol and finally with 10 ml of distilled water. After that, the wine sample intended for investigation in the amount of 50 ml, to which 10 g of ammonium sulfate and 0.5 ml of 2-heptanol solution with a concentration of 98% are added, is passed under vacuum through the prepared cartridge at a speed of 0.5 ml/min. After completion of the process, the cartridge is washed with distilled water in the amount of 10 ml and blown with an air jet for 5 min. Desorption of volatile compounds from the surface of the cartridge is carried out with a mixture of ethyl acetate and methylene chloride in a ratio of 1:1 (by volume) in the amount of 4 ml. The obtained extract is treated with anhydrous sodium sulfate, to clean it and bind the phenolic compounds, and concentrated by evaporation until a volume of 0.5 ml is obtained. After the respective preparation, the extract is injected into the GC-MS chromatograph.

The cartridge, made of hydrophobic supercrosslinked polystyrene, is previously subjected to preparation, which includes the successive passage through it of methylene chloride in an amount of 5 ml, then 5 ml of ethanol and finally 10 ml of distilled water.

În 50 ml de vin alb supus investigării se adaugă 10 g de sulfat de amoniu şi 0,5 ml de soluţie 2-heptanol cu concentraţia de 98%, după care amestecul obţinut este trecut sub vid prin cartuşul pregătit cu o viteză de 0,5 ml/min. După finalizarea procesului cartuşul, pe suprafaţa căruia sunt adsorbite substanţele aromatice, este spălat cu 10 ml de apă distilată şi suflat cu un jet de aer timp de 5 min. In 50 ml of white wine under investigation, 10 g of ammonium sulfate and 0.5 ml of 2-heptanol solution with a concentration of 98% are added, after which the mixture obtained is passed under vacuum through the prepared cartridge at a speed of 0.5 ml/min. After completing the process, the cartridge, on the surface of which the aromatic substances are adsorbed, is washed with 10 ml of distilled water and blown with an air jet for 5 min.

Desorbţia compuşilor aromatici de pe suprafaţa cartuşului se realizează cu o soluţie de eluţie, alcătuită din 2 ml de acetat de etil şi 2 ml de clorură de metilen, amestecul obţinut fiind trecut prin cartuş şi colectat aparte. În extractul obţinut se adaugă sulfat de sodiu anhidru în cantitate ce asigură adsorbţia apei din acesta, apoi se separă de sare şi se concentrează prin evaporare cu ajutorul unui curent slab de aer până la obţinerea unui volum de 0,5 ml. The desorption of aromatic compounds from the surface of the cartridge is carried out with an elution solution, consisting of 2 ml of ethyl acetate and 2 ml of methylene chloride, the mixture obtained being passed through the cartridge and collected separately. Anhydrous sodium sulfate is added to the obtained extract in an amount that ensures the adsorption of water from it, then it is separated from the salt and concentrated by evaporation with the help of a weak air stream until a volume of 0.5 ml is obtained.
