Optimisation of a biotechnological procedure for selective fractionation of bioactive inositols in edible legume extracts

Abstract

Removal of interfering LMWCs from inositol-enriched extracts was successfully achieved using a clean and easily scalable fractionation methodology. This biotechnological procedure not only represents high interest for the production of bioactive food ingredients but for applications in other research areas.

The Cyclitol L-(+)-Bornesitol as an Active Marker for the Cardiovascular Activity of the Brazilian Medicinal Plant <i>Hancornia speciosa</i>

“…5) L-(+)-Bornesitol is a methyl myo-inositol found in several plant species. 6) It has been identified by gas chromatography in decaffeinated and non-decaffeinated coffee beverages, 7) chickpeas, lentils, 8) and legumes such as carob beans 9) and grass peas. 10) Bornesitol has also been reported as responsible for the sweet taste of Drypetes floribunda stem and Sapindus rarak pericarp.…”

Carob Kibble: A Bioactive‐Rich Food Ingredient

“…The concentration of d ‐pinitol ranged from 5% to 7.5% (dry weight of the powder) whereas myo ‐inositol and chiro ‐inositol were minor components with concentrations of 0.5% to 1% and 0.1%, respectively (Baumgartner and others ). Higher d ‐pinitol (methyl‐inositols) contents (113 mg/g) in carob has been reported in a recent study from Spain which was much higher than those in other legumes such as soybean (3.5 mg/g), chickpea (2.0 mg/g), and lentil (2.0 mg/g) (Ruiz‐Aceituno and others ). When compared with other d ‐pinitol‐rich plants, carob pods are the least expensive source with the highest content (Turhan , ).…”

“…In addition to the main sugars (sucrose, glucose, and fructose), carob kibble contains low concentration of other sugars such as maltose, raffinose, stachyose, verbascose, xylose, inositols, and others (Ruiz‐Aceituno and others ). Inositols are polytols of cyclohexane with the empirical formula C 6 H 12 O 6 .…”

Assessment of Maillard reaction evolution, prebiotic carbohydrates, antioxidant activity and α-amylase inhibition in pulse flours

“…Other important constituents in pulses are a-galactosides, also known as the raffinose family oligosaccharides (RFOs) with a recognized prebiotic effect at a maximum daily dose of 3 g due to their indigestible a(1-6) links; however, at higher doses, RFOs could give rise to flatulence and interference with the digestion of other nutrients (Martínez-Villaluenga et al 2008). Galactosyl-cyclitols, present in legume seeds, are also considered as important phytochemicals related to disease prevention (Ruiz-Aceituno et al 2013). Moreover, the in vitro antioxidant activity of legume extracts has been mainly ascribed to phenolic compounds, underlying their benefits in prevention of cancer, ageing and chronic diseases (Zhao et al 2014).…”
