Definitions

  • the present invention relates to a process for producing a high-purity maltose.
  • maltose has been available as a saccharified starch product with a maltose content of about 40-50 w/w % based upon the weight of the dry solid solute (all percentages are used in the specification mean "weight percentages on dry solid basis” unless otherwise specified) which is obtainable by subjecting a liquefied starch solution to the action of a malt enzyme.
  • a starch sugar solution containing maltose is passed through a column of an anion exchange resin.
  • Japanese Patent Publication No. 46,290/77 discloses a process for producing a high-purity maltose comprising preparing a starch sugar solution substantially consisting of dextrin and about 65% maltose, and applying the solution to an anion exchange resin of OH-form to adsorb the maltose constituent and also to remove the dextrin constituent.
  • Japanese Patent Publication No. 20,579/79 discloses a process for producing a high-purity maltose which comprises applying a starch sugar solution, containing glucose and maltose, to a column packed with an anion exchange resin of SO 3 2- - or SO.sub.
  • the present inventors have investigated processes for producing a high-purity maltose using a strongly-acidic cation exchange resin, more particularly, of alkali metal- or alkaline earth metal-form, instead of an anion exchange resin which has the above described disadvantages.
  • a high-purity maltose is easily obtainable by admitting a feed starch sugar solution with a maltose content of at least 70% and water to a column packed with a strongly-acidic cation exchange resin of alkali metal- or alkaline earth metal-form thereby fractionating the solution into a high-dextrin fraction, a high-dextrin, maltose fraction, a high-maltose fraction, a high-maltose.glucose fraction, and a high-glucose fraction (the terms "high-A fraction” and "high-A.B fraction” as used in the specification shall mean the eluted fractions rich in A, or rich in A but highly contaminated with B); and recovering the high-maltose fraction.
  • the drawing shows the elution pattern of the feed solution upon the fractionation into fractions A through E, i.e., the high-dextrin fraction, high-dextrin.maltose fraction, high-maltose fraction, high-maltose.glucose fraction, and high-glucose fraction, respectively.
  • the feed starch sugar solution usable in the present invention may be almost any substantially-ketose-free solution of aldoses derived from starch. Such a feed solution results in a high-maltose fraction; and with a maltose content of 90%, typically 93% or higher, in a high yield when subjected to the fractionation according to the present invention.
  • feed starch sugar solution may be a saccharified starch solution obtained by subjecting starch to the actions of starch-degrading enzymes, e.g., ⁇ - and ⁇ -amylases, and starch-debranching enzyme, or may be an aqueous solution of a commercially-available starch sugar product having a maltose content of at least 70%.
  • the strongly-acidic cation exchange resin of alkali metal- or alkaline earth metal-form usable in the invention may be, for example, one or more members of styrene-divinylbenzene copolymer resins bearing sulphonyl groups of alkali metal- or alkaline earth metal-form, such as Na + , K + , Ca 2+ , or Mg 2+ .
  • Commercially-available resins are, for example, "Dowex 50WX2", “Dowex 50WX4", and “Dowex 50WX8", products of Dow Chemical Company, Midland, Mich., U.S.A., "Amberlite CG-120", a product of Rohm & Haas Company, Philadelphia, Pa.
  • a resin with a nominal particle size of about 0.01-0.5 mm is packed in one or more columns.
  • the bed depth preferred in the invention is generally 7 m or longer. If two or more columns are used, they are cascaded to give a total bed depth of 7 m or longer.
  • any column can be used regardless of its material, size, and shape so far as the objectives of the invention can be attained therewith.
  • the column may be, for example, of glass, plastic or stainless steel, and its shape may be, for example, in cylindrical or square pillar form, but it should be designed to give the most effective laminar flow possible when the feed starch sugar solution is applied to the column packed with the resin.
  • One or more column(s) is packed with a strongly-acidic cation exchange resin of alkali metal- or alkaline earth metal-form, in an aqueous suspension, to give a total bed depth of 7 m or longer.
  • the feed starch sugar solution While keeping the temperature in the column(s) at 45°-85° C., the feed starch sugar solution, at a concentration of about 10-70 w/w %, in an amount of about 1-60 v/v % against the bed volume, is admitted into the column(s) and then charged upwards or downwards with water at a flow rate of about SV 0.1-2.0 to effect fractionation of the material starch sugar solution into a high-dextrin fraction, a high-dextrin.-maltose fraction, a high-maltose fraction, a high-maltose.glucose fraction, and a high-glucose fraction, in the given order.
  • the high maltose-fraction is then recovered.
  • the eluted fractions are generally collected in about 1-20 v/v % against the bed volume, they may be distributed automatically into the fractions.
  • the amount of water required for substantial fractionation of the feed starch sugar solution can be sharply reduced, and the maltose constituent in the solution can be recovered in higher purity, higher concentration, and higher yield.
  • the previously obtained high-dextrin.maltose fraction, the feed starch sugar solution, and the previoiusly obtained high-maltose.glucose fraction are applied successively to the column in the given order.
  • the high-maltose fraction thus obtained can be used intact, it may be, if necessary, treated further as follows.
  • the high-maltose fraction may be subjected to conventional purification steps, e.g., filtration, decolorization and/or deionization.
  • the purified product is, for example, concentrated to obtain a syrup, or crystallized to obtain a mascuit which may be spray-dried into crystalline powder, or separated into mother liquor and maltose crystals of much higher purity.
  • the high-purity maltose thus obtained is extremely useful in various applications, e.g., for production of food products or pharmaceuticals.
  • the feed starch sugar solutions used in this experiment were prepared from commercially-available starch sugar products as listed in Table I, products of Hayashibara Company, Limited, Okayama, Japan, by dissolving or diluting them in water to give respective concentrations of 45 w/w %.
  • each feed starch sugar solution listed in Table I was admitted to the column in an amount of 5 v/v % against the bed volume, and fractionated by charging 75° C. hot water at a flow rate of SV 0.4 through the column and the high-maltose fraction, with a maltose content of 93 % or higher, was recovered.
