Definitions
- the invention relates to a process for fractionating a shea extract allowing the fractionation, separation and recovery of the two constituent factions of shea, namely olein and shea stearin.
- shea extract a material derived from the fruit or seeds of shea.
- the shea extract can be obtained by traditional method, mechanical pressure, cold extraction and/or solvent extraction. These techniques are detailed in the body fat manual of Alain KARLESKIND (TEC & DOCS, 1993 ).
- the shea extract is a shea butter.
- a shea butter is a vegetable fatty substance which is solid at room temperature, extracted from the fruit or the seeds of the shea tree, and which melts at temperatures close to those of the skin.
- the shea butter used in the present invention can be obtained by traditional method, solvent extraction and/or cold extraction.
- the shea butter used in the present invention is preferentially refined and comes from organic farming certified CEE/NOP organic by FR-BIO-01 and ECOCERT SA.
- the shea butter can undergo a degumming step, a bleaching step, a deodorization step and/or a neutralization step.
- the degumming step also called the degumming step, removes the latex from the vegetable butter.
- latex is a liquid substance, with a more or less thick consistency, secreted by certain plants or by certain fungi and circulating in the laticiferous ducts.
- raw vegetable butter is degummed by mixing the oil with water or steam and passing the mixture through centrifuges which separate the gummy residue from the oil.
- the discoloration step eliminates colored pigments (chlorophylls and carotenoids), residual soaps, traces of mucilage, heavy metals, in particular through the use of activated earths.
- Bleaching earths are generally plastic clays that are simply dried and finely ground to increase their contact surface. You can also use activated charcoal.
- the deodorization step is intended to remove odorous substances (essentially sulfur compounds) from the decolorized oil. This operation is commonly carried out under vacuum at high temperature. This involves steam distillation under vacuum of these compounds which result from the degradation of the oil.
- neutralization eliminates all phospholipids, traces of metals and products degraded by oxidation.
- the shea butter used in the present invention can be raw shea butter.
- Raw shea butter means shea butter that has not undergone any refining step.
- fractionation process is meant a process for separating a mixture into several successive fractions whose physical properties are different.
- the fractionation consists in separating the shea extract into fractions of different physical characteristics.
- the shea extract can thus be separated into an oil commonly referred to as the shea olein fraction and a solid fraction, the shea stearin, whose melting point is higher than the starting shea extract.
- the shea olein fraction is a fraction of fatty acids, liquid at ambient temperature and whose mass percentage of oleic acid is greater than the mass percentage of each fatty acid which composes it. More specifically, the mass percentage of oleic acid is at least 50% relative to the total mass of fatty acid of the shea olein fraction.
- the shea stearin fraction is a fatty acid fraction, solid at room temperature and whose mass percentage of stearic acid is greater than the mass percentage of each fatty acid which composes it. More specifically, the mass percentage of stearic acid is at least 45% relative to the total mass of fatty acid of the shea stearin fraction
- a “mass percentage” is the ratio of the mass of a first compound relative to the total mass of a mixture of compounds or composition, reduced to a percentage.
- Such plant fractions can have various uses in the food and cosmetics industry.
- JP2011132207A cosmetic compositions comprising a raw material derived from shea butter have been described.
- compositions of edible creams comprising a raw material derived from shea butter have been described.
- cocoa butter equivalents comprising shea stearin have been disclosed.
- the nature or the quantity of the solvents used during the solvent fractionation processes may be unsuitable both from an economic point of view and from a toxicological and environmental point of view.
- the solvents most commonly used to fractionate the shea extract are aliphatic solvents of the hexane type or preferably acetone.
- Hexane is an organic solvent considered to be toxic and is classified as CMR category 2. In addition, given its physico-chemical properties, this solvent presents a danger in handling and even more so on an industrial scale (flash point-23, 3°C / auto-ignition temperature 233°C).
- acetone is a volatile and flammable solvent (flash point at -18°C) widely used in the chemical industry.
- flash point at -18°C flash point at -18°C
- its high volatility requires in industrial processes a volume of solvent that may be unsuitable from an economic and environmental point of view.
- the present invention makes it possible to fractionate directly without subsequent treatment, a shea extract using a solvent system and to simultaneously recover a fraction of shea olein and shea stearin, the two fractions being in accordance with the requirements of the cosmetic and food industry regulations.
- the solvents in the solvent system are biobased.
- a biobased compound or an organic composition in which the organic carbon present in the compound or composition is of plant origin is qualified by a radiocarbon analysis according to one of the following standards ASTM D6866, EN 16640 or EN 16785-1.

Description
L'invention concerne un procédé de fractionnement d'un extrait de karité permettant le fractionnement, la séparation et la récupération des deux factions constitutives du karité que sont l'oléine et la stéarine de karité.The invention relates to a process for fractionating a shea extract allowing the fractionation, separation and recovery of the two constituent factions of shea, namely olein and shea stearin.
On entend par extrait de karité, une matière issue du fruit ou des graines de karité. L'extrait de karité peut être obtenu par méthode traditionnelle, pression mécanique, extraction à froid et/ou extraction par solvants. Ces techniques sont détaillées dans le manuel des corps gras d'
De manière préférentielle, dans la présente demande, l'extrait de karité est un beurre de karité.Preferably, in the present application, the shea extract is a shea butter.
Au sens de la présente invention, un beurre de karité est un corps gras végétal solide à température ambiante, extrait du fruit ou des graines de karité, et qui fond à des températures voisines de celles de la peau.Within the meaning of the present invention, a shea butter is a vegetable fatty substance which is solid at room temperature, extracted from the fruit or the seeds of the shea tree, and which melts at temperatures close to those of the skin.
Le beurre de karité utilisé dans la présente invention peut être obtenu par méthode traditionnelle, extraction par solvant et/ou extraction à froid.The shea butter used in the present invention can be obtained by traditional method, solvent extraction and/or cold extraction.
Le beurre de karité utilisé dans la présente invention est de manière préférentielle raffiné et est issu de l'agriculture biologique certifié CEE/ NOP organic par FR-BIO-01 et ECOCERT SA.The shea butter used in the present invention is preferentially refined and comes from organic farming certified CEE/NOP organic by FR-BIO-01 and ECOCERT SA.
Pour ce faire, le beurre de karité peut subir une étape de dégommage, une étape de décoloration, une étape de désodorisation et/ou une étape de neutralisation.To do this, the shea butter can undergo a degumming step, a bleaching step, a deodorization step and/or a neutralization step.
L'étape de dégommage, également appelée étape de démucilagination permet d'ôter les latex du beurre végétal. En botanique, on appelle latex une substance liquide, à consistance plus ou moins épaisse, sécrétée par certaines plantes ou par certains champignons et circulant dans les canaux laticifères. Lors du raffinage, le beurre végétal brut est dégommé en mélangeant l'huile avec de l'eau ou de la vapeur et en faisant passer le mélange dans des centrifugeuses qui séparent le résidu gommeux de l'huile.The degumming step, also called the degumming step, removes the latex from the vegetable butter. In botany, latex is a liquid substance, with a more or less thick consistency, secreted by certain plants or by certain fungi and circulating in the laticiferous ducts. During refining, raw vegetable butter is degummed by mixing the oil with water or steam and passing the mixture through centrifuges which separate the gummy residue from the oil.
L'étape de décoloration permet d'éliminer les pigments colorés (chlorophylles et caroténoïdes), les savons résiduels, les traces de mucilage, des métaux lourds notamment par l'utilisation de terres activées. Les terres décolorantes sont généralement des argiles plastiques simplement séchées et finement broyées pour accroître leur surface de contact. On peut également utiliser des charbons activés.The discoloration step eliminates colored pigments (chlorophylls and carotenoids), residual soaps, traces of mucilage, heavy metals, in particular through the use of activated earths. Bleaching earths are generally plastic clays that are simply dried and finely ground to increase their contact surface. You can also use activated charcoal.
L'étape de désodorisation est destinée à éliminer les substances odorantes (essentiellement les composés soufrés) de l'huile décolorée. Cette opération est couramment réalisée sous vide à haute température. Il s'agit, d'un entraînement à la vapeur d'eau sous vide de ces composés qui résultent de la dégradation de l'huile.The deodorization step is intended to remove odorous substances (essentially sulfur compounds) from the decolorized oil. This operation is commonly carried out under vacuum at high temperature. This involves steam distillation under vacuum of these compounds which result from the degradation of the oil.
La neutralisation ou la désacidification consiste à éliminer les acides gras libres de l'huile démucilaginée. Les techniques de neutralisation des huiles végétales les plus utilisées sont :
- La neutralisation chimique ou alcaline (par la soude ou par la chaux).
- La neutralisation physique (par distillation).
- Chemical or alkaline neutralization (using soda or lime).
- Physical neutralization (by distillation).
Outre l'élimination des acides gras libres, la neutralisation permet d'éliminer la totalité des phospholipides, les traces de métaux et les produits dégradés par oxydationIn addition to the elimination of free fatty acids, neutralization eliminates all phospholipids, traces of metals and products degraded by oxidation.
Le beurre de karité utilisé dans la présente invention peut être un beurre de karité brut. On entend par beurre de karité brut un beurre de karité n'ayant subi aucune étape de raffinage.The shea butter used in the present invention can be raw shea butter. Raw shea butter means shea butter that has not undergone any refining step.
On entend par procédé de fractionnement un procédé de séparation d'un mélange en plusieurs fractions successives dont les propriétés physiques sont différentes.By fractionation process is meant a process for separating a mixture into several successive fractions whose physical properties are different.
Dans le cas de la présente invention, le fractionnement consiste à séparer l'extrait de karité en fractions de caractéristiques physiques différentes. L'extrait de karité peut ainsi être séparé en une huile communément désignée comme la fraction d'oléine de karité et une fraction solide, la stéarine de karité, dont le point de fusion est plus élevé que l'extrait de karité de départ.In the case of the present invention, the fractionation consists in separating the shea extract into fractions of different physical characteristics. The shea extract can thus be separated into an oil commonly referred to as the shea olein fraction and a solid fraction, the shea stearin, whose melting point is higher than the starting shea extract.
Au sens de la présente invention, la fraction d'oléine de karité est une fraction d'acides gras, liquide à température ambiante et dont le pourcentage massique en acide oléique est supérieur au pourcentage massique de chaque acide gras qui la compose. De manière plus précise, le pourcentage massique en acide oléique est d'au moins 50% par rapport à la masse totale d'acide gras de la fraction d'oléine de karité.Within the meaning of the present invention, the shea olein fraction is a fraction of fatty acids, liquid at ambient temperature and whose mass percentage of oleic acid is greater than the mass percentage of each fatty acid which composes it. More specifically, the mass percentage of oleic acid is at least 50% relative to the total mass of fatty acid of the shea olein fraction.
De manière analogue, la fraction de stéarine de karité est une fraction d'acide gras, solide à température ambiante et dont le pourcentage massique en acide stéarique est supérieur au pourcentage massique de chaque acide gras qui la compose. De manière plus précise, le pourcentage massique en acide stéarique est d'au moins 45% par rapport à la masse totale d'acide gras de la fraction de stéarine de karitéSimilarly, the shea stearin fraction is a fatty acid fraction, solid at room temperature and whose mass percentage of stearic acid is greater than the mass percentage of each fatty acid which composes it. More specifically, the mass percentage of stearic acid is at least 45% relative to the total mass of fatty acid of the shea stearin fraction
Dans la présente demande un « pourcentage massique » est le rapport de la masse d'un premier composé par rapport à la masse totale d'un mélange de composés ou composition, ramené à un pourcentage.In the present application, a “mass percentage” is the ratio of the mass of a first compound relative to the total mass of a mixture of compounds or composition, reduced to a percentage.
De telles fractions végétales peuvent avoir divers usages dans l'industrie alimentaire et cosmétique.Such plant fractions can have various uses in the food and cosmetics industry.

Par ailleurs, la nature ou la quantité des solvants utilisés lors des procédés de fractionnement par solvant peuvent être inadaptées tant du point de vue économique que d'un point de vue toxicologique et environnemental.Moreover, the nature or the quantity of the solvents used during the solvent fractionation processes may be unsuitable both from an economic point of view and from a toxicological and environmental point of view.
Les solvants, les plus communément utilisés pour fractionner l'extrait de karité sont les solvants aliphatiques de type hexane ou de manière préférentielle l'acétone.The solvents most commonly used to fractionate the shea extract are aliphatic solvents of the hexane type or preferably acetone.
La demande
L'hexane est un solvant organique considéré comme toxique et est classé CMR de catégorie 2. De plus, au vu de ses propriétés physico-chimiques ce solvant présente un danger en manipulation et encore plus à l'échelle industrielle (point éclair-23,3°C / température d'auto-inflammation 233°C).Hexane is an organic solvent considered to be toxic and is classified as CMR category 2. In addition, given its physico-chemical properties, this solvent presents a danger in handling and even more so on an industrial scale (flash point-23, 3°C / auto-ignition temperature 233°C).
En revanche, l'acétone est un solvant volatil et inflammable (point éclair à - 18°C) très utilisé dans l'industrie chimique. Cependant, sa haute volatilité, nécessite dans les procédés industriels un volume de solvant pouvant être inadapté d'un point de vue économique et environnemental.On the other hand, acetone is a volatile and flammable solvent (flash point at -18°C) widely used in the chemical industry. However, its high volatility requires in industrial processes a volume of solvent that may be unsuitable from an economic and environmental point of view.
La présente invention permet de fractionner directement sans traitement ultérieur, un extrait de karité à l'aide d'un système de solvant et de récupérer simultanément une fraction d'oléine de karité et de stéarine de karité, les deux fractions étant conformes aux exigences des règlementations de l'industrie cosmétique et alimentaire.The present invention makes it possible to fractionate directly without subsequent treatment, a shea extract using a solvent system and to simultaneously recover a fraction of shea olein and shea stearin, the two fractions being in accordance with the requirements of the cosmetic and food industry regulations.
