Definitions

  • the invention relates to a process for the production of guar meal, which, if it is dissolved in water, yields a transparent solution of varying viscosity, i.e. low to very high, whereby the process supplies good yields of the pure meal in spite of extensive purification.
  • Transparent, high-viscosity solutions of pure guar meal are primarily of great significance in the foodstuffs industry.
  • Guar meal is used as a thickening agent in the textile and explosives industries, as a binding agent in the paper industry, as a flocculent in ore production, as an aid in the extraction of natural gas and petroleum, in the pharmaceutical and cosmetic fields and as a thickening agent, emulsifier and co-stabilizer in foodstuffs.
  • low viscosity guar meal is used for spray-embedding vitamins, for example, in order to increase their storage stability. Beyond that, the use of guar meal in sprays guarantees a nearly monomolecular distribution of the substance and a resulting even re-absorption, which is desirable in the case of asthma medications and various anti-allergics. Due to the extraordinarily low protein content of the pure guar meal, there is no danger of developing an allergic reaction to a medication containing this substance. Additional applications in this field are the formulation of retard tablets and use as an agent for reducing cholesterol levels. In the field of medicines, very viscous guar meal is also used as a stabilizer in contrast media.
  • Guar meal has also proven itself as, among other things, an ideal dietetic agent, since its components, the so-called galactomannans, are not affected by enzymes of the human stomach and small intestines. This is to be expected, since in the re-absorbing part of the human digestion system neither ⁇ -mannanase nor ⁇ -mannosidase nor ⁇ -galactosidase is present, which would be necessary to break down these components. Since the components of the guar meal are not involved in the human metabolism, guar meal is in no way to be viewed as a carrier or supplier of calories. Since guar meal is composed of completely neutral polysaccharides, i.e. galactomannans, which have neither uronic acid nor other ionic groups, they represent completely harmless material from a physiological standpoint.
  • a further advantage with regard to its use as a food supplement is its complete taste neutrality. It is used in calorie-reducing or fat-reducing foods or drinks, which are frequently felt by the consumer to be “thin”.
  • the addition of pure guar meal to these products lends a “creamy” consistency to them.
  • Guar meal is used in the production of fruit juices in order to re-suspend the fruit pulp evenly, in puddings and cremes it is used as a thickener, and in ice creams, milkshakes, mousse and similar products it is used as a stabilizer.
  • guar meal and xanthane An advantage of this combination of guar meal and xanthane consists in that the gel from these two components melts at body temperature and is therefore exceptionally well-suited for the production of jelly-type foods, as a carrier substance in the administration of medications and the like. Guar meal and xanthane are also used together as co-stabilizers in the production of salad dressings, since this combination, in contrast to guar meal used by itself, is acid-resistant.
  • Guar meal is obtained from the endosperm of the guar seed ( cyamopsis tetragonobolus ).
  • Guar meal consists primarily of galactomannans, i.e. polysaccharides the main chain of which is linked in the 1>4 direction by ⁇ glycosidic bonds and is composed of mannose that is partially linked to galactose through primary OH groups.
  • the ratio of non-substituted mannose to mannose substituted with galactose is approximately 2:1, wherein the substituted units are not strictly alternating, but instead are arranged in groups of two or three in the polygalactomannan molecules.
  • the guar-galactomannans form highly viscous solutions even in low concentrations with water. 1 percent-by-weight) solutions of commercially standard guar meal in water yield viscosities of approximately 3,000 to 6,000 mPa.s.
  • the guar-seed is mechanically treated, whereby about 35 parts of unpurified guar endosperm halves and about 60 parts of guar meal are obtained.
  • the guar meal consists essentially of the germ of the seed, the scraped-off seed hulls and small endosperm parts.
  • the endosperm completely envelops the germ and in turn is surrounded by the seed hull.
  • At the point of contact between the endosperm and seed hull there is a protein rich, aleuron-like cell layer, the cells of which are tightly interlocked with the endosperm.
  • the unpurified endosperm halves can be further purified mechanically and supply splits of varying quality with regard to their protein content, their components that cannot be hydrolyzed by acid (A.I.R.) and the husk content.
  • A.I.R. acid
  • the characterization “split” typical in professional circles is interchangeable with the term “endosperm halves”.
  • guar meal already has broad application, it is desirable to improve its degree of purity and along with this its physical and physiological characteristics.
  • the purity of the guar meal is of great importance, in particular for its application in the foodstuffs field.
  • a better utilization of the neutral, non-ionic main components of the endosperm so that these can increasingly be used in the corresponding industrial sectors instead of cellulose derivatives that dissolve clear in water, other polysaccharides or synthetic polymers that dissolve clear in water.
  • the floating fraction of ground endosperm such as guar CSA 200/50 can contain up to 25% proteins and the settling fraction, which makes up 75% of the pure meal, contains about 1.5 to 1.6% protein.
  • the settling fraction is, for example, suitable for the production of cationic derivatives, which, after being dissolved, yield clear aqueous solutions.
  • a disadvantage of this process is that finely milled hull fragments are likewise found in the settling fraction.
  • a further disadvantage is the use of halogenated solvents, since a specific weight of 1.47 to 1.48 kg/l is required. Proteins possess a density of 1.3 kg/l and the galactomannans a density of 1.5 to 1.55 kg/l, depending upon the particular moisture content.
  • the guar meal produced with the described process is only appropriate for technical applications; this guar meal cannot be used in the foodstuffs field since residues of the halogenated solvent used (10 ppb were detected in fractions extracted with ethanol) remain in the end product.
  • Halogenated solvents are toxic and caustic to various degrees and frequently contain allergenic characteristics. Also for environmental reasons, one should refrain from this process.
  • a further process for the production of pure guar meal was proposed as early as 1969. It consisted of an alkali treatment of pre-soaked splits at increased temperatures, wherein 100 parts of alkali were absorbed by 100 parts of SPS. The large quantity of alkali, i.e. NaOH, had to be washed out. This was done with cold water in a ratio of one part SPS (single purified splits) to 80 parts H 2 O and in a dehydration step with isopropanol (IPA) in which the residual NaOH of the purified splits was neutralized by acetic acid.
  • SPS single purified splits
  • IPA isopropanol
  • Another known process for the production of pure guar meal is the treatment of guar splits with acid.
  • This process supplies a product of outstanding quality; i.e. the resulting material supplies yields, when dissolved in water, solutions of great clarity with simultaneously greater viscosity.
  • a disadvantage of this process consists in the relatively expensive procedure with multiple washing and neutralization steps.
  • special apparatuses that make the process very costly are needed for an acid treatment.
  • An initial precondition for obtaining pure guar meal is the improvement of the starting material, the so-called splits.
  • the splits covered with a hull constitute up to 42.5 percent by weight of the seed.
  • the hull-endosperm overlapping parts which amount to 13.5% by weight of the seed, are essentially insoluble in water.
  • the germ of the seed encompasses the remaining 44%.
  • the pure guar meal obtained according to the invention is most advantageously produced from splits that have a protein content of 4.2% and an A.I.R. portion of 1.8%.
  • splits can be produced after an alkaline treatment using 10 to 40% caustic soda, preferably 33%, at room temperatures, but preferably at increased temperatures.
  • the splits purified in this way which can optionally be washed with water or processed further unwashed, can still be significantly improved for the purposes of the invention, in that phospholipids and other “non-polar” substances are washed out.
  • an aqueous alcohol solution preferably aqueous isopropanol (IPA)
  • IPA aqueous isopropanol
  • the alkaline splits are washed with water and milled at a desired moisture content.
  • the degree of hydration during the milling significantly influences the characteristics of the milled end product.
  • the higher the moisture content during grinding in a technically workable mass the greater the quantity of polysaccharides to become dissolved, i.e. the yield of active galactomannans is that much higher. This can be explained by the expansion of the cell volume due to the high amount of moisture.
  • the swollen cells are forced through a defined opening or crack, whereby the cell membrane can tear, assuming that the swollen particles are significantly larger than the openings (the elasticity of the cells likewise plays an important role).
  • the galactomannans are released from the cells destroyed in this way, which is not the case with cells that are not destroyed. In these cases, the galactomannans remain inside the intact cells and do not contribute effectively to the viscosity of the solution.
  • a great advantage of this invention lies in the 25% recovery of the abraded peripheral cell layers, i.e. in an extreme reduction of the environmental impact.
  • An additional advantage of the present invention lies in the simplification of the process. Only a few less steps are necessary to obtain a pure product with higher solubility and viscosity.
  • Another advantage of this invention consists in the possibility of producing products for solutions with viscosities, for example, as low as 35 mPa.s and such as are measured up to 6000 to 9,000 mPa.s with a 1% concentration in water at 25° C.
  • Another advantage of the invention consists in producing pure guar products, the protein content of which is as low as 0.2 to 0.5%.
  • the new process is exceptionally environmentally friendly, since about 25% of the sifted peripheral cell layers can be recovered.
  • the abrasion that results in the process described here can furthermore be used in textile printing as a thickening agent. This means an optimal utilization of the starting material.
  • a derivation of the galactomannans of the guar meal is of significance for its cold water solubility.
  • the derivation e.g. carboxylmethylation, hydropropylation, cationization, etc.
  • one or more non-ionic, anionic or cationic groups are added, whereby the etherized hard-to-access galactomannans can be dissolved even at 25° C.
  • the derivation typically occurs in succession to the purification.
  • the use of the derived guar meal is not allowed in food application.
  • derived guar meal, in particular cation-active guar meal is used in cosmetic products such as hair conditioner, body lotions and in similar use.
  • cationic guar meal derivatives which can be produced from a pure guar meal obtained by the process according to the invention, are the hydroxypropyl-trimethyl ammonium chloride guar meals.
  • the etherization can preferably be performed in two main steps:
  • an initial step in which the cationic etherization agent is diffused in the guar meal under alkaline conditions and under an inert gas atmosphere at a temperature from around 20 to 55° C., preferably around 30 to 50° C., and then suspended in an aqueous alcohol solution, in particular a water-isopropanol-solution that contains 25 to 70% by weight of isopropanol,
  • the first step can in particular be conducted in the presence of sodium hydroxide, whereby of 100 parts of guar meal, approximately 1 to 4 parts by weight are accounted for by sodium hydroxide; this step can last 15 to 60 minutes.
  • the second step (the actual etherization) can last approximately 45 to 120 minutes.
  • the resulting cationic product is next brought into contact with air again at the same temperature conditions in order to slightly depolymerize the product to the desired end viscosity.
  • the product is then purified one or more times by washing with an aqueous alcoholic solution, in particular water/isopropanol.
  • an acid e.g. acetic acid
  • the cationic guar meal is separated, for example by filtration or centrifuging, and then dried.
  • the quantity of etherization agent that can be used is selected so that one obtains a cationic guar meal with a degree of substitution (SG) within the range of 0.01 to 0.4.
  • the degree of substitution (SG) can be defined as the number of substituents of 2.3-epoxypropyl-trimethyl ammonium chloride that is added per hexose unit of guar meal.
  • the hydroxypropyl-trimethyl ammonium chloride guar meals can have an average molecular weight of about 50,000 to 8,000,000.
  • the cationic guar meal obtained by the process according to the invention in particular the hydroxypropyl-trimethyl ammonium chloride guar meals, can be used in particular for the production of cosmetic formulations.
  • the invention thus also relates to the use of a hydroxypropyl-trimethyl ammonium chloride guar meal produced by etherization of a guar meal obtained by the process according to the invention in clear aqueous cosmetic formulations that are specified for use on hair and/or skin and are to be washed out or rinsed off as a conditioning agent and/or as a deposition aid for additional conditioning agents in the dilution of these cosmetic formulations.

  • the reaction temperature is indirectly increased by means of 90° C. hot water to 70° C. and then kept constant.
  • reaction mixture is sifted through a M20 sieve, and in so doing,
  • the +M20 fraction displays a NaOH content 5-6% and is washed twice with cold water, in each case using 6 parts tap water to 1 part of the unwashed +M20 fraction.
  • a viscosity of 7,000 mPa.s was measured at 20 rpm and 25° C., after the homogenous solution, obtained by impact, of the swollen splits had cooled overnight.
  • the 1% aqueous solution was produced in a household mixer at the highest speed at roughly 900° C.
  • the quantity of swelled splits to be dissolved was calculated at a water content of 10%.
  • the transparency of the aqueous solution of such products is 93 to 95%.
  • the viscosity of a 1% aqueous solution can be set at 6,000 to 7,000 mPa.s depending on reaction conditions.
  • the product designated as ⁇ M20 and cleaned in the above-described manner is a guar gum with a viscosity of 1,000 to 1,500 mPa.s at 1% concentration, which can serve as the basis for significantly improved guar products or derivatives.
  • the ⁇ M20 fraction as well can also be processed for applications that use alkaline oxidized guar products or derivatives.
  • a field of application would be polyester printing, for example.
  • the temperature of the heterogenous reaction mixture is increased to and maintained at 70° C. for 30 minutes.
  • reaction mixture is then cooled down to 55° C.
  • the washed splits have a water content of 72% and are ground finer than M150 in the usual manner in a hot air current in a swing-hammer crusher.
  • the ground product still contains roughly 2% NaOH and shows a viscosity of 4,200 mPa.s at a concentration of 1%, based on 10% water with a 6.8 pH.
  • peripheral cell layers were then abraded for 15 minutes at 70° C. in an open reactor 6.5 percent of weight ⁇ M20 can be removed.
  • the still adhering, treated peripheral cell layers can be abraded mechanically by an intensive rubbing of the +M20 fraction, e.g., in a household coffee grinder at the lowest grinding speed.
  • peripheral cell layers can also be abraded in aqueous alcohols with intensive stirring.
  • Example III The product from Example III was ground and 400 g of this ground product was re-suspended in 1600 g of a 25 percent by weight of aqueous isopropanol solution. One hundred ml of a 30 percent by weight of NaOH solution was added. The suspension was heated to 70° C. in a nitrogenous atmosphere for 30 minutes while constantly stirring. This reaction temperature was maintained for 1 hour, then the suspension was cooled down to 55° C. The stirring was interrupted and after the reaction product was precipitated, the excess was poured off.
  • reaction product was washed with 1,000 ml of a 50 percent by weight isopropanol solution and then treated with 10 ml of glacial acetic acid in order to neutralize a stoichiometric quantity of NaOH.
  • reaction product thus comes into contact with atmospheric oxygen so that the final viscosity of the cationic guar product could be controlled.

  • This cationic guar displayed a 880 mPa.s viscosity (based on 10% moisture) at 1% concentration in water and a light transmission (clarity) of 94.2%.
  • reaction product was removed from the reactor and washed twice with water in a ratio of 1:6. Due to the very rapid water absorption of the cleaned carboxymethyl splits not treated with borax, their dwell time in water was limited to 2 minutes in each case. The weight of the highly swelled splits was 2,640 g. A dehydration step with isopropanol (1,500 g was used) was therefore necessary.
  • reaction mixture Attained the desired temperature of 68° C.
  • the reaction temperature of 68°-72° C. was maintained for 20 minutes. Most of the water was then drawn off from the reaction mixture by ventilation and indirect heating for 23 minutes.
  • the reaction mixture was sifted through M20, thus obtaining 30 g of ⁇ M20 and 437 g of +M20 (10.1% H 2 O content).
  • the +M20 fraction was washed twice with water, in each case using 6 parts tap water to 1 part of the unwashed +M20 fraction. The respective washing times were 4 and 5 minutes.
