Abstract:
Abstract Soybean foods forming a substantial part of Asian diet have still more expanded into European diet. Raffinose-series oligosaccharides (RSO) are important constituents of soya beans and they can be found also in soybean products. These oligosaccharides can be considered potentially prebiotic for their capability of influencing the composition of the host’s intestinal microbiota. The aim of the present paper was to determine the oligosaccharide content in various soybean products. Enzymatic assay has been used for the determination of oligosaccharides. RSO have been found in all tested

Abstract:
The oligosaccharide compositions of 33 lupin seed accessions and cultivars, from 10 species, are reported. Seed weights varied from 3.8 to 66.6 g/100 seeds. Total oligosaccharide content ranged from just under lo%, to almost 23% dry matter. In all cases the quantity of oligosaccharides (raffinose, stachyose and verbascose) was higher than that of disacharides (sucrose and melibiose). Verbascose ranged from 0.0 to 33.4% of total oligosaccharide content, and raffinose from 4.7 to 47.4%. Stachyose was the predominant and most constant sugar in majority of the seeds examined, the highest level (75

AbstractStachyose, raffinose and related flatulence-producing oligosaccharides (α-galactosyl derivatives of sucrose) are associated with desiccation tolerance and storability of seed germplasm. Orthodox seeds of species with a sucrose-to-oligosaccharide ratio of <1.0 have storability half-viability periods >10 years while those >1.0 have a storability half-viability period <10 years. Seeds vary in their composition of oligosaccharides and some accumulate α-galactosyl derivatives of cyclitols.

Anti-nutritional compounds are among the obstacles to the use of pea seeds as a protein source in both feed and food. These compounds are poorly digested by both monogastric animals and humans. There are three main oligosaccharides in pea: raffinose, stachyose and verbascose (raffinose family oligosaccharides – RFOs).

Abstract:
Common bean (Phaseolus vulgaris L.) is a nutritionally complete food, but contains antinutritional compounds that reduce digestibility. One group of compounds includes the raffinose family oligosaccharides (RFOs) (raffinose, stachyose, and verbascose), which are partly responsible for flatulence after beans are eaten. RFOs stabilize cell membranes during seed desiccation and when the seed rehydrates during germination. While low levels of RFOs are desirable nutritionally, high levels may enhance germination and emergence, particularly in cold, wet soils. Eight landraces selected for high and l

Abstract:
The raffinose family of oligosaccharides (RFO) is a series of complex carbohydrates stored in seeds of many plant families, especially in legumes. The digestive system of nonruminant animals, including that of humans, cannot break down all of the chemical bonds in these carbohydrates; therefore, catabolism is achieved anaerobically by intestinal flora. The resulting digestive problems reduce acceptance and limit the widespread consumption of these otherwise nutritious seeds. To demonstrate a solution to this problem, transgenic lines of pea ( Pisum sativum L.) expressing the α-galactosidase ge

Phloem transport is along hydrostatic pressure gradients generated by differences in solute concentration between source and sink tissues. Numerous species accumulate raffinose-family oligosaccharides (RFOs) in the phloem of mature leaves to accentuate the pressure gradient between source and sinks. In this study, metabolic engineering was used to generate RFOs at the inception of the translocation stream of Arabidopsis thaliana, which transports predominantly sucrose. To do this, three genes, GALACTINOL SYNTHASE, RAFFINOSE SYNTHASE and STACHYOSE SYNTHASE, were expressed from promoters specifi

The raffinose family of oligosaccharides (RFO) function as transport carbohydrates in the phloem, storage compounds in sink tissues, and as putative metabolic agents that combat plant stresses. Research on the RFO pathway has focused on seed biology and plants that transport raffinose as their primary photoassimilate. In contrast, few studies have explored this pathway in woody species. As such, this thesis investigated the fundamental function of the RFO enzymes in hybrid poplar, with emphasis on galactinol synthase (GolS), an enzyme key to the pathway.

Thesis (PhD)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: The raffinose family of oligosaccharides (RFOs) are α1,6-galactosyl extensions of sucrose (Suc-Galn) unique to the plant kingdom. Their biosynthesis is mediated via α1,6-galactosyltransferases which catalyse the formation of raffinose (Raf, Suc-Gal1), stachyose (Sta, Suc-Gal2) and higher oligomers (Suc-Galn, n ≥ 13) in a stepwise manner. RFOs are well known for their historical roles as phloem translocates and general carbon storage reserves. In recent years their physiological roles have expanded to include potential func
