“…The gel could be a polysaccharide gel containing soluble dietary fibres. Similar observation was made in L. campestrae [9] and linseed [20] also, which consists of uronic acids and arabinoxylan. The health benefits of dietary fibre are very well documented [21][22][23][24] and in that context L. sativum, particularly its bran can be used as source of dietary fibre like flax seed which is already made available over the counters in developed countries.…”

Garden cress (Lepidium sativum) belonging to the family Cruciferae grown in India, Europe and US is an underutilized crop. The edible whole seed is known to have health promoting properties. Hence, it was assumed that these seeds can be a functional food. A preliminary work on chemical composition of seeds was carried out and the possibility of using it as nutraceutical food ingredient in dietary fiber formulation was explored. Three fractions namely whole meal (WM), endosperm and bran were analyzed for chemical composition. The yield of the endosperm and the bran fraction were 72 and 28%, respectively. The WM, endosperm and bran had 22.5, 27.7 and 12.6% protein, 27.5, 33.1 and 6% fat, 30, 13.6 and 75% dietary fibre (DF), and 1193.00, 945.15 and 1934.57 mg% potassium respectively. The major protein on SDS-PAGE was of 29.5 kDa. The most abundant amino acid was glutamic acid (19.3%) and the essential amino acid, leucine was the highest (8.21 +/- 0.01%) and methionine the lowest (0.97 +/- 0.02%). The major fatty acid was linolenic acid (30.2%) and low amount of erucic acid (3.9%) was also present. Bran having high water holding capacity and high DF, its use as source of DF was explored. The product contained 12% protein, 4% fat and 74.3% DF and exhibited desirable functional properties such as dispersibility, gelling ability, stability, formed homogenous mild alkaline suspension and was comparable to proprietary DF.

“…In linseed a similar gel forms, which consists mainly of uronic acids and arabinoxylan. 23 The variation in content of soluble dietary übre polysaccharide residues was large, due to the very small amounts of these components. Insoluble dietary übre polysaccharides had CV generally less than 10%.…”

“…The rheological properties vary among sources and fractions of the flax mucilage, from a viscous fluid to a viscoelastic fluid and to an elastic element, with elasticity and viscosity increasing with increasing proportions of arabinoxylan to RG I (Wannerberger et al, 1991;Cui et al, 1994). Warrand et al (2005aWarrand et al ( , 2005b found three populations of arabinoxylan-rich polymers based on molecular size ranging from 200,000 g mol 21 to over 5,000,000 g mol 21 .…”

Novel Rhamnogalacturonan I and Arabinoxylan Polysaccharides of Flax Seed Mucilage

2008

View full text Add to dashboard Cite

The viscous seed mucilage of flax (Linum usitatissimum) is a mixture of rhamnogalacturonan I and arabinoxylan with novel side group substitutions. The rhamnogalacturonan I has numerous single nonreducing terminal residues of the rare sugar L-galactose attached at the O-3 position of the rhamnosyl residues instead of the typical O-4 position. The arabinoxylan is highly branched, primarily with double branches of nonreducing terminal L-arabinosyl units at the O-2 and O-3 positions along the xylan backbone. While a portion of each polysaccharide can be purified by anion-exchange chromatography, the side group structures of both polysaccharides are modified further in about one-third of the mucilage to form composites with enhanced viscosity. Our finding of the unusual side group structures for two well-known cell wall polysaccharides supports a hypothesis that plants make a selected few ubiquitous backbone polymers onto which a broad spectrum of side group substitutions are added to engender many possible functions. To this end, modification of one polymer may be accompanied by complementary modifications of others to impart functions to heterocomposites not present in either polymer alone.
