Description
~2073~0 A SOI.VENT MIXTURE, AND A PROCESS USING S~CH A MIXTURE
FOR THE EXTRACTION OF LIPIDS AND POLYPHENOLS FROM FLAKED
SUNFLOWER SEEDS
This invention relates to a novel solvent mix-ture which can be used for the solid-liquid extraction, conveniently in a single-step run, of lipids and poly-phenols from flaked sunflower seeds in order to obtain proteinaceous concentrates.
The present invention provides a solvent mixture composed of a hydrocarbonaceous solvent, ethanol and water. The mixture may thus be a biphasic 3-component mixture of solvents.
The hydrccarbonaceous solvent is preferably an alkane, normally an aliphatic alkane, preferably one having several carbon atoms such as normal hexane.
The hydrocarbonaceous compound can be from 40% to 70% on a volume basis relative to the total mixture and the other two components, ethanol and water, may vary from 60~ to 30~ on the same basis with a respective ratio, that is, ethanol to water by volume, variable from 95:5 to 50:50.
The present invention also provides a process for the solid-liquid extraction of lipids and polyphenols from flakes hulled sunflower seeds, which involves the use, as the extraction solvent, of a solv~nt mixture composed of a hydrocarboanceous solvent, ethanol and water.
The solid liquid extraction process may be carried out by any of theprocedures suggested by the technical literature. The adoption of the procedure disclosed in the prior Patent No. 1.119.781 of March 16, 1982 has proved to be particularly advantageous.
The solid-liquid extraction process described - 1 - ~;~
~2~73Z~O
therein comprises supplying fresh solvent or solvent mixture to one of a plurality of extraction vessels ar-ranged in series, each of which vessels contains the solid material and is provided with a solvent inlet, a solvent outlet, an operating stirring means and a filter-ing element for preventing the escape of solid material of more than a predetermined size through the solvent outlet, the filtering elementt extending into the vessel in the proximity of the stirring means so that the agita-tion of the solvent or solvent mixture by the stirring means reduces the tendency of the solid mate.rial to clog the filtering element; passing solvent with entrained extracted substance~s) from the said one extraction vessel through the other extraction vessel in series; and then, after extraction of extractible substance(s) from the solid material in said one extraction vessel, switching the supply of fresh solvent or solvent mixture to the next downstream extraction vessel, removing solid material from said one extraction vessel, and recharging the said one extraction vessel with fresh solid material, with the said one extraction vessel connected in series down-stream of the previously most downstream extraction ves-sel.
That process makes it possible to extract a few components with a solvent or a mixture of two or more solvents through a number, n, of serially arranged containers, the containers being maintained, during the entire extraction XUTI, with their contents constantly stirred.
The solvent (or solvents) is fed to (and with-drawn from) the several vessels with a value of the rate of flow (unitary) which is selected within a well defined range, usually from 2 cubic metres p~r hour and per square metre to 15 m3/h/m2, the flow through the serially ar-ranged vessel being continuous.
.~
~Z(173~D
In practice, after having charged each ~essel with the appropriately comminuted solid material, each vessel is filled with solvent and tirring is started.
Fresh solvent is then fed to the first container so that the solvent already contained in it is diluted and the extraction becomes very efficient.
The solvent drawn from the first vessel is sent to the next extraction vessel and the same operation is repeated, and that operation is subs~quently and se rially repeated for all the n extraction vessels.
Once the solid material contained in the first extraction vessel has been exhausted (in the sense that the extractible substance has been extracted), it is dumped and fresh solvent is fed to that vessel, the latter being then shifted to the last place in the series.
Feed of fresh solvent is switched from the first extraction vessel to the next and so on.
Inasmuch as, or each vessel~ about 10~ of the solid material (the finest portions) passes into the solvent stream, there is the necessity of providing, in addition to the serially arranged extraction vessels, a ~ilter: the latter separates the solid matter entrained by the solvent stream from the liquid phase and the extrac-tion is completed.
The practicability and the efficiency of the process are closely bound to a number of variables and these must be correlated to each other.
It has already been pointed out that a basic parameter is the specific (unitary) rate of flow of the solvent which is fed to and drawn from every extraction vessel: it must normally range from 2 to 15 m3/hour/m2.
Other parameters must be properly selected, such as the height:diameter ratio of the vessel, the geometrical characteristics of the filtering member, , ~ ~
, ~
.~ ~
~2~73~'0 the size of the filtering member openings, the material which composes the filtering member, the thickness of the filtering member, the kinematic viscosity of the slurry, and the intensity of stirring maintained in the vessel.
The specification of the above mentioned prior patent states that anyone skilled in the art will be capable of selecting the appropriate values of the para-meters enumerated above so as to optimize the process and the efficiency of the extraction consistently with the solid material being handled, its size, the solvent and all the other characteristics involved.
However, the said prior patent does not contain any hint of the possible use of a ternary mixture with different phases, and it seems, conversely, that the process disclosed in said prior patent finds its elective application just in the use of ~ single solvent or of a mixture of mutally miscible and m~tually compatible solvents.
Surprisingly, and this is the basis of the present invention, it has now been found that it is pos-sible to use, to the end of simultaneously extracting from sunflower seeds more than one undesirable component, a mixture comprised of three solvents which are distri-buted over di~ferent phases.
The adoption of such a mixture enables a high extraction yield to be obtained and, if it is used in the extraction procedure described above, such a result is combined with the ease and appreciability of that process.
The solid-liquid extraction process is prefer-ably carried out within a temperature of from 20C to 50C, for a time of from 30 minutes to 6 hours and a weight (kg)- volume (litre) ratio of the flaked seed ~2~)73ZO
to the solvent mixture ranging from 1:1 to 1:10 (that is, froml kg to 1 litre, to 1 kg to 10 litres).
Analytical methods for the chemical characterization of the sunflower seeds and the products obtained therefrom.
Moisture, ash and crude fibre have been deter-mined according to the standard methods of A.O.A.C.
(Association of Official Analytical Chemists, 12th Edition, 1975)-The proteinic contents were expressed in terms of macroKieldahl nitrogen multiplied by the coefficient 5.70. The total lipids were determined according to the petroleum ether method as reported in A.A.C.C. No.
30-26. The polyphenol compounds were measured with the colorimetric method by Bittoni et al (Riv.Ital.Sost.
Grasse, 54, 421, 1977). The total sugars were determined with the method by M. Dubois et al (Analytical Chemistry, 28, 350-356, 1968), modified in that the separation of the individual sugars was omitted and only the total sugar contents were considered, as present in the product.
The P.D.I. (Protein Dispersibility Index) as used for determining the quantity of nitrogen capable of being dispersed in water under natural pH conditions was in agreement with the method reported in A.O~C.S.
(Me~hod Ba 10 65, Revised 1969).
