The amino acid composition of the proteinaceous components of konjac mannan, seed endosperm galactomannans and xanthan gum

The amino acid composition of the proteinaceous components of konjac mannan, seed endosperm galactomannans and xanthan gum. Anderson, D. M. W.; Howlett, J. F.; McNab, C. G. A. (Chem. Dep., Univ. Edinburgh EH9 3JJ, UK). Food Hydrocolloids, 1(2), 95-9 (English) 1986. CODEN: FOHYES. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Anal. 39300-88-4 and 11138-66-2 are cas registry numbers of chemicals which are used as reagents here. data are presented for the amino acid compns. of com. samples of konjac mannan [37220-17-0], locust bean gum [9000-40-2], tara gum [39300-88-4], Sesbania (Dhaincha) gum [69522-36-7] and xanthan gum [11138-66-2]. Konjac mannan contains high proportions of aspartic acid, glutamic acid and glycine. Major amino acids in xanthan gum are alanine, glutamic acid, aspartic acid and glycine. There are similarities in the amino acid compns. of the seed endosperm galactomannans studied; all contain major amts. of glutamic acid, aspartic acid and glycine and similar proportions of all the other amino acids, with the exception of tara gum and Sesbania gum, which contain high proportions of alanine and histidine resp. All the gums studied have very low hydroxyproline contents, in marked contrast to the values reported previously for the tree exudates from the leguminous genera Acacia (gum arabic), Astragalus (gum tragacanth) and Prosopis (gum mesquite). .

Semipermeable membrane from konjak mannan

Semipermeable membrane from konjak mannan. (Zushi Kagaku Kenkyusho Y.Several substances are used for example 9005-38-3 and 9004-32-4 which are their cas registry numbers. K., Japan). Jpn. Kokai Tokkyo Koho JP 58214305 A2 13 Dec 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D013-00. APPLICATION: JP 82-98223 8 Jun 1982. DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Konjak mannan [37220-17-0] soln. (0.5-5%) optionally contg. binders (e.g., galactomannan [11078-30-1], CM cellulose [9004-32-4], Na alginate [9005-38-3]) was treated with alkali and spread over a flat surface and dried to obtain a semipermeable membrane which is water- and heat-resistant. .
