Definitions

  • the present invention relates to a process for fractionating soy molasses.
  • Soy Molasses (SM) of acceptable stability contains ⁇ 60% water and numerous solutes.
  • Carbohydrates are preponderant, totaling -60% on dry solids basis. The remainder consists of a very large number of compounds. These are customarily characterized by classes
  • Each class may comprise a fairly large number of specific molecules.
  • This process is designed for use with primary fractionation of SM aiming to obtain fractions distinguished by greatly narrowed distribution profiles.
  • no chemical transformations are involved and the fractions fall into the category of food materials equivalent by definition to SM. Consequently, some of these fractions can conceivably already constitute desirable end products. Others could be convenient starting materials for the recovery of specific compounds by simple and efficient secondary separations.
  • soy molasses of 64% solids 100grs contain 36grs or two mols of H 2 O. The remaining 64grs are a mixture of polar compounds.
  • strong interactions of solute/solute molecules obtain. These will increase with decrease in water content (i.e. with increase in SM solids content) and decrease with dilution by water. Specifically these interactions explain the apparent water solubility of molecules that per se would not be described as such.
  • SM contains compounds that were extracted from defatted soy by virtue of the alkanol content of the extracting aqueous solvent. Such compounds can be present as a stable solution in SM by virtue of the solvation effects.
  • the dependence of SM composition on alkanol content of extracting solvent has now been found, according to the present invention, to tailor a separation process based on aqueous solvents, wherein the ratio of water to the organic solvent component plays a primary role.
  • fractionation by solvents consisting of water and at least one water soluble organic compound and driven by controlled adjustment of concentration, of solvent composition and of temperatures can be achieved.
  • sucrose solubility at about 70% EtOH.
  • Soy carbohydrates may be expected to have a similar solubility pattern. While in the simple tricomponent system W-sucrose-ethanol phase separation consists of solid sucrose in equilibrium with its saturated solution, in the 4 multicomponent system water-SM-EtOH there may be several solid species precipitating as well as an additional liquid phase formation.
  • Solvents of organic component of limited solubility will form a two liquid phase system in contact with SM over a range of solvent to SM ratios and so will solvents of which the organic component is fully miscible, this occurring in zones of high C/O ratios.
  • Water in such system may be regarded as distributing between an aqueous and an organic phase whereby a parameter of control, i.e., hydration level, is established which would be absent or extremely limited in the EtOH-H 2 O-SM 6 system, which is the system used industrially to obtain soy molasses and which, in turn, may explain the absence of reported observations potentially leading to the present invention..
  • solvent selected from the group consisting of compounds containing only carbon, hydrogen and oxygen atoms, said compounds having a C/O ratio of at least 3 and having up to 6 carbon atoms.
  • said solvent is a C 3 - C & alcohol.
  • the separated aqueous phase is subjected to solid/liquid separation before recombination of the liquid component of the aqueous phase with a further aliquot of solvent.
  • such solids are separated as an additional product of lower C/O than the product contained in the corresponding solvent phase.
  • solids that precipitate to form an aqueous slurry are retained in the slurry and said slurry is subjected as such to the next extraction.
  • solvent extracts are subjected to staged dehydration and evaporation operations so as to recover from such extract successively at least two products of increasing C/O ratio.
  • Fig. 1 is a graphic representation comparing C/O ratios for different alkanol/water systems
  • Fig. 2 is a schematic illustration of a general process scheme according to the present invention.
  • Fig. 3 is a schematic illustration of a specific process scheme according to the present invention.
  • Fig. 4 is a schematic illustration of a further process scheme according to the present invention.
  • Fig. 5 is a schematic illustration of a process scheme for recovery of solutes.
  • Examples A series of Soy Molasses fractionation according to the present invention is carried out utilizing ordinary lab glassware for contacting molasses with solvent.
  • the traditional separator/ funnels are generally unsuitable due to molasses viscosity.
  • Round-bottomed flasks provide for convenient mixing by shaking and flat-bottomed beakers which are also convenient for magnetic stirring are used.
  • the low viscosity light solvent phase is easily decanted.
  • Thermostatic water baths centrifugues spinnig small and larger tubes, of 10ml and 50ml size are used and the system is set up for rapid instrumental analysis of characterising constituents by HPLC.
  • Compounds (or compound classes) of particular interest may be determined optically by UV or IR absorption.
  • Amount grs 18 26 26 R C/0 3.28 3.81 1.1
  • Example 1 was repeated to obtain 310grs of solvent extract.
  • This example corresponds to Fig. 5.
  • Solvent extracts contain solutes that are essentially water soluble e.g. carbohydrates and solutes that are markedly hydrophobic. The former are retained by virtue of the water content of the solvent, the latter by virtue of the organic component that has a ratio of C/O>2.
  • Group 1 and Group 2 are named Group 1 and Group 2 (hereinafter referred to as G1 and G2 respectively).
  • G1 can be recovered by controlled dehydration since their solubility decreases with the decrease of water content in the solvent. Such dehydration is easily obtainable by azeotropic distillation. Most organic solvent components of C/O>2 form operationally convenient azeotropes which permit lowering of the water content from the initial value to zero without recourse to an additional component acting as entrainer. Thus carbohydrates in an extract can be precipitated by azeotropic dehydration and collected as a single product or a solubility graduated series of products. Naturally, the anhydrous organic phase will be saturated with respect to the compounds that precipitate. The recovery of such residual amounts is obtained by appropriate recycles.
  • G2 compounds retained in an anhydrous organic phase can be recovered by complete solvent evaporation. However this will recover concurrently residual G1.
  • FIG. 5 schematizes the foregoing.
  • the solids (and possibly aqueous slurries) formed in the Dehydrating Distillation are collected as a sequence of fractions thus further refining fractionation.

Abstract

Procédé servant à fractionner des mélasses de soja, ce qui permet d'obtenir des fractions successives, dans lesquelles le rapport global C/O entre des composés ne contenant que des atomes de carbone, d'hydrogène et d'oxygène est augmenté pour chaque fraction successive, et consiste à effectuer une série d'extractions successives au moyen du mélange de ces mélasses avec un solvant afin d'établir un équilibre, à séparer la phase de solvant obtenue de la phase aqueuse, à mélanger une phase aqueuse séparée provenant d'une extraction précédente avec une autre aliquote de solvant afin d'établir un équilibre, à séparer la phase de solvant obtenue de la phase aqueuse et à récupérer un produit représentant une fraction de mélasses de soja depuis chaque extrait successif de liquide par des procédés connus, le solvant étant sélectionné dans le groupe constitué par des composés ne contenant que des atomes de carbone, d'hydrogène et d'oxygène, ces composés présentant un rapport C/O d'au moins 3 et possédant 6 atomes de carbone maximum.
