Patent number: 8173837Abstract: L-citrulline may be extracted from watermelons using a process which does not require rigorous extraction with alcoholic and/or acidic solvents, or treatment at high temperatures. In the process, the watermelon juice is contacted with an adsorbent effective for adsorption of L-citrulline thereon, and the juice is separated therefrom. The L-citrulline on the adsorbent may then be eluted and recovered. Lycopene-containing microparticles may also be separated from the watermelon juice prior to contact with the adsorbent.Type: GrantFiled: December 3, 2009Date of Patent: May 8, 2012Assignee: The United States of America, as represented by the Secretary of AgriculureInventor: Wayne W. Fish

Patent number: 4601829Abstract: A process for purifying lysine in a lysine production process, which involves passing a solution containing lysine over a cation exchange resin such that lysine adsorbs onto the resin, eluting adsorbed lysine from the resin with an aqueous solution of ammonia to produce a lysine-containing elution liquid, passing the elution liquid directly to a reverse osmosis membrane system, and concentrating the lysine-containing elution liquid with the reverse osmosis membrane system such that ammonia is selectively removed from the lysine containing elution; the aqueous ammonia which is separated from the lysine may be recycled through the cation exchange resin to regenerate the resin or to elute more lysine from the resin.Type: GrantFiled: December 24, 1984Date of Patent: July 22, 1986Assignee: Ajinomoto Co., Inc.Inventors: Tetsuya Kaneko, Masaru Saeki, Kiyoshi Tanaka, Tetsuya Kawakita

Patent number: 4111714Abstract: To recover amino acids from raw sugar juice, as obtained in beet extraction, the juice is treated with acid or with lime to coagulate impurities which are separated off. The juice may be treated before or after coagulation with a pectin-cleaving enzyme. The juice so pretreated can be directly passed through a strong cation exchanger and a weak anion exchanger whereby the amino acids are adsorbed. Switchover to a new cation exchanger is initiated when betaine flows out the column. Elution is effected, preferably with an ammonium compound, and eluate is collected, preferably each fraction being enriched in a different amino acid. The sugar juice may be concentrated and crystallized in known manner and is of comparatively high purity.Type: GrantFiled: April 8, 1976Date of Patent: September 5, 1978Assignee: Pfeifer & LangenInventors: Hermann Hippchen, Hans-Georg Schneider, Renate Schwingeler
