Pectinex Ultra SP-L, a com. enzyme preparation with fructosyltransferase activity, was successfully immobilized by covalent binding to Fe₃O₄-chitosan- magnetic nanoparticles. Immobilization carried out according to a 2³-full factorial design where glutaraldehyde concentration, activation time and time of contact between enzyme and support were selected as the independent variables and immobilization yield as the response. The highest immobilization yield (94.84%) was obtained using 3.0% (volume/volume) glutaraldehyde and activation and contact times of 180 and 30 min, resp. The immobilized biocatalyst, which showed for both hydrolytic and transfructosylating activities optimum pH and temperature of 7.0 and 60°C, resp., retained 70 and 86% of them after 6 cycles of reuse. A kinetic/thermodn. study focused on thermal inactivation of the immobilized construct indicated high thermostability at temperatures commonly used for fructo-oligosaccharides (FOS) production Maximum FOS concentration obtained in lab-scale experiments was 101.56 g L^-1, with predominant presence of 1-kestose in the reaction mixture The results obtained in this study suggest that the immobilized-enzyme preparation may be effectively exploited for FOS production and easily recovered from the reaction mixture by action of a magnetic field.

Antioxidant dietary fiber (DF) and bioactive compounds are considered important factors for nutritional and health-promoting properties of cereal products. Breads fortified with wholegrain cereals and seeds are increasingly demanded, making it necessary to investigate the influence of these ingredients on nutritional value of breads. The aim of this study was to assess the impact of wheat flour fortification on the composition in antioxidant DF, non-glycemic oligosaccharides, polyphenols (PC), and antioxidant activity (AA) of the final bread products. Breadmaking affected bioactive compounds in different way depending on flour composition Although wholegrain flour was the most sensitive to breadmaking process, both multigrain and wholegrain breads stood out for their level in DF, PC and AA, whereas white bread showed higher fructan content. Results showed that replacing of refined flour with other cereals (rye, oat), fiber (wheat bran, wheat fiber) and seeds (flaxseeds, sunflower, sesame) would improve the potential health benefits of breads.

Effects of ultra-high pressure on effective synthesis of fructooligosaccharides and fructotransferase activity using Pectinex Ultra SP-L and inulinase from Aspergillus niger was written by Kawee-Ai, Arthitaya;Chaisuwan, Worraprat;Manassa, Apisit;Seesuriyachan, Phisit. And the article was included in Preparative Biochemistry & Biotechnology in 2019.Synthetic Route of C18H32O16 This article mentions the following:

In this study, various levels of ultra-high pressure (UHP) were combined with the enzymic synthesis of the fructooligosaccharide (FOS) using Pectinex Ultra SP-L and inulinase. The combination enhanced the FOS yields up to 2.5- and 1.5-fold, resp., compared to atm. condition (0.1 MPa). However, the enzymic reaction was dependent on the levels of pressure, the reaction times, and the initial sucrose concentrations The combined UHP and inulinase showed that the maximum FOS yield (71.81%) was obtained under UHP at 200 MPa for 20 min with 300 g/L of initial sucrose as a substrate, while the FOS yield (57.13%) using Pectinex Ultra SP-L was obtained under UHP at 300 MPa for 15 min with 600 g/L of initial sucrose as a substrate. The FOS composition produced by Pectinex Ultra SP-L under the UHP was 1-kestose (GF₂), nystose (GF₃), and 1F-fructofuranosylnystose (GF₄), whereas the FOS produced by inulinase composed of only GF₂ and GF₃. The combined UHP is a useful tool in the industrial application for FOS production HighlightsUHP activated the activity of Pectinex Ultra SP-L yet inactivated inulinasePressure level, time, and sucrose concentration significantly affect FOS yields under UHPUHP enhanced FOS production with time-saving benefits within 15-20 min.

Fructan and antioxidant metabolisms in plants of Lolium perenne under drought are modulated by exogenous nitric oxide was written by Rigui, Athos Poli;Carvalho, Victoria;Wendt dos Santos, Andre Luiz;Morvan-Bertrand, Annette;Prud′homme, Marie-Pascale;Machado de Carvalho, Maria Angela;Gaspar, Marilia. And the article was included in Plant Physiology and Biochemistry (Issy-les-Moulineaux, France).Recommanded Product: 470-69-9 This article mentions the following:

Drought is a major environmental factor that can trigger oxidative stress and affect plant growth and productivity. Previous studies have shown that exogenous nitric oxide (NO) can minimize oxidative stress-related damage through the modulation of antioxidant enzyme activity. Fructan accumulation also has an important role in drought tolerance, since these carbohydrates participate in osmoregulation, membrane protection and oxidant scavenging. Currently, there are few studies investigating NO-regulated fructan metabolism in response to abiotic stresses. In the present study, we sought to determine if treating plants of Lolium perenne with S-nitrosoglutathione (GSNO), a NO donor, improved drought tolerance. Two-month-old plants received water (control), GSNO and reduced glutathione (GSH) as foliar spray treatments and were then maintained under drought or well-watered conditions for 23 days. At the end of drought period, we evaluated growth, pigment content and antioxidant and fructan metabolisms None of these conditions influenced dry mass accumulation, but the leaves of plants treated with GSNO exhibited a slight increase in pigment content under drought. GSNO treatment also induced 1-SST activity, which was associated with a 3-fold increase in fructan content. GSNO-treated plants presented higher GR activity and, consequently, increased GSH levels. L. perenne cv. AberAvon was relatively tolerant to the water stress condition employed herein, maintaining ROS homeostasis and mitigating oxidative stress, possibly due to fructan, ascorbate and glutathione pools.

This study presents an anal. method for the quantification of fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) in cereals and cereal-based products, considering diverse ingredients, such as different cereals in addition to wheat, pulses, or pseudocereals. All carbohydrates have been separated, identified, and quantified with a high-performance anion-exchange chromatog. system coupled with a pulsed amperometric detection (HPAEC-PAD). The total fructan content and the average d.p. (DP_av) have been determined after enzymic hydrolysis to the monomers glucose and fructose, on the basis of the principle of the official method for fructan quantification in food products, AOAC 997.08. The methods for extraction, separation, and detection as well as fructan determination are based on several other studies and were modified in order to minimize interferences in the anal. The method has been validated with regard to the limits of detection and quantification, the linearity, the repeatability, and the accuracy as well as the DP_av of the fructans.
