  • Patent number: 5942611
    Abstract: A new process for recovering high purity natamycin from fermentation broth containing natamycin comprises the steps of adjusting the pH of the broth to above about 10 and adding an amount of a water-miscible solvent, such as isopropanol, sufficient to dissolve the natamycin in the broth, followed by removing insoluble solids from the pH-adjusted broth, followed by lowering the pH of the broth to a level sufficient to precipitate the natamycin, and removing the natamycin from the broth.

  • Patent number: 5795398
    Abstract: A method for separating sucrose and a second dissolved component from a sucrose-containing solution, preferably a beet-derived sucrose-containing solution, wherein the solution is subjected to a first fractionation by a continuous or sequential chromatographic simulated moving bed process to yield a sucrose-enriched fraction and a fraction enriched with the second dissolved component. The resulting fraction enriched with the second component is subjected to a second chromatographic fractionation that is a simulated moving bed or batch type process, to yield a second sucrose-enriched fraction and a second fraction enriched with the second dissolved component wherein both fractions have an improved yield or purity.

  • Patent number: 5612072
    Abstract: The invention relates to a process for the production of substantially non-alcoholic beer by a continuous yeast treatment at a low temperature. In the process, wort which has been clarified and possibly treated by evaporating and/or with an adsorbing agent is passed through a packed column reactor containing immobilized yeast at a temperature ranging between the freezing point of wort and 10.degree. C. The yeast is reactivated at 2.degree. to 15.degree. C. for 10-30 hours. If required, the reactor can be regenerated.

  • Patent number: 5601863
    Abstract: A polydextrose having improved color, flavor and decreased reactivity toward food ingredients having amine functionality. The polydextrose comprises a water-soluble highly branched polydextrose having been prepared by a process which comprises melting dextrose in the presence of a food-acceptable acid catalyst. The improved polydextrose of this invention has substantially no reducing glucose groups. Another aspect of this invention is directed to a method of making the above-described improved polydextrose which comprises exposing unimproved polydextrose to an environment capable of chemically transforming the reducing glucose groups contained in the unimproved polydextrose, thereby substantially eliminating their reducing properties. An improved polymaltose prepared by heating maltose in the presence of a food-acceptable acid catalyst and chemically transforming the reducing glucose groups contained in the polymaltose, thereby eliminating their reducing properties, is also described.
