Branched oligosaccharide phosphate (BOS-P) and oleyl BOS-P (OA-BOS-P) were prepared from potato starch with a high phosphate content by limited amylolysis with α-amylase and exhaustive digestion with glucoamylase and oleylation of BOS-P through a lipase-catalyzed solid-phase synthesis. The
Potato pulp by-product rich in galactan-rich rhamnogalacturonan I (RG I) was investigated as a new source of oligosaccharides with potential prebiotic properties. The efficiency of selected monocomponent enzymes and multi-enzymatic preparations to generate oligosaccharides/oligomers from potato RG I
The inhibitory effect of phosphorylated oligosaccharides, which were prepared from potato starch, on the formation of calcium phosphate in vitro were investigated. Phosphorylated oligosaccharides from potato were fractionated by ion-exchange chromatography into two fractions, PO-1 and PO-2. Fraction
OBJECTIVE
In vitro studies have suggested that fructo-oligosaccharides (FOS) and resistant starch (two fermentable non-digestible carbohydrates) display different fermentation kinetics. This study investigated whether these substrates affect the metabolic activity and bacterial composition of the
A bi-enzymatic system using two multi-enzymatic preparations (Depol 670L and Gamanase 1.5L) was investigated for the production of prebiotic galacto/galacto(arabino)-oligosaccharides and oligomers with well-defined degree of polymerisation (DP) from potato galactan-rich rhamnogalacturonan I.
Raffinose family oligosaccharides (RFOs) are involved in the storage and transport of carbon and serve as compatible solutes for protection against abiotic stresses like drought or cold. RFOs are usually transported in plant species that load sugars symplastically into the phloem. Loading probably
This work shows an optimized enzymatic hydrolysis of high molecular weight potato galactan yielding pectic galactan-oligosaccharides (PGOs), where endo-β-1,4-galactanase (galactanase) from Cellvibrio japonicus and Clostridium thermocellum was used. For this, response surface
Galactose-rich oligosaccharides/oligomers (oligo-RG I) were produced by the enzymatic treatment of potato galactan-rich rhamnogalacturonan I (RG I) with endo-β-1,4-galactanase and Depol 670L multi-enzymatic preparation. The digestibility study revealed that 81.6 and 79.3% of RG I and its
Acetylated trigalacturonides and rhamnogalacturonan I (RG-I)-derived oligosaccharides were isolated from a Driselase digest of potato tuber cell walls by ion-exchange and size-exclusion chromatography. The oligosaccharides were structurally characterized by fast atom bombardment-mass spectroscopy,
Two glucanotransferases, disproportionating enzyme 1 (StDPE1) and disproportionating enzyme 2 (StDPE2), were repressed using RNA interference technology in potato, leading to plants repressed in either isoform individually, or both simultaneously. This is the first detailed report of their combined
Enzymatic hydrolysis of water-soluble polysaccharides from potato peel waste (PPPW) generates low molecular weight oligosaccharides with a yield of 63%. The oligosaccharides generated from potato peel polysaccharides (OPPP) were purified by Superdex-30 column. The results showed the presence of 8
Effects of sucrose, raffinose and stachyose on pasting, thermal, and rheological properties of sweet potato starch (SPS) were investigated. The results indicated that pasting temperature of SPS increased with increasing sugar concentration in the order of stachyose>raffinose>sucrose. Addition of
Potato pulp is a high-volume side-stream from industrial potato starch manufacturing. Enzymatically solubilized β-1,4-galactan-rich potato pulp polysaccharides of molecular weights >100 kDa (SPPP) are highly bifidogenic in human fecal sample fermentations in vitro. The objective of the present study
