“…Hydrocolloids are a large group of high molecular weight biopolymers that are utilized as thickeners, gels, emulsifiers, and stabilizers in food, pharmaceutical, and cosmetic products (Andrade et al, 1999). Up to date, there have been extensive researches on hydrocolloids and their usability, but researchers are looking for new hydrocolloid resources that, while available and inexpensive, can compete with conventional, so-called commercial hydrocolloids (Bakhshy et al, 2019). Among these hydrocolloid sources, the types extracted from plant seeds, especially galactomannans, have become of special importance because of the absence of toxicity and high accessibility.…”

The dominant objective of this study was to extract and purify galactomannan from Gleditsia caspica seeds. In addition to chemical analysis and investigation of the basic physicochemical and functional properties of the extracted galactomannan, other tests have been performed to determine the structural and thermal properties. The FT-IR spectra authenticated availability of O-H, C-H, and C-O stretching vibrations in the galactomannan conformation. The extracted galactomannan had amorphous structure with very low crystallinity which was obtained from XRD analysis. The obtained DSC and TGA plots showed thermal events including one endothermic and one exothermic peak that are typical for natural polysaccharides. The H-NMR analysis of the extracted galactomannan demonstrated peaks at δ 4.901 and 4.705 ppm, which were affiliated with availability of H-1 (α) (α-galactopyranosyl) and H-2 (β) (β-mannopyranosyl). The images obtained from SEM confirmed that the galactomannan surface was relatively smooth and uniform. Novelty Impact StatementThe galactomannan was extracted and purified from Gleditsia caspica seeds.Comprehensive characterization of obtained galactomannan authenticated its chance to be applied as thickeners or stabilizers in food formulations as a new source of plant-based hydrocolloid.

Reserve mobilisation exhibits a biphasic pattern during seedling establishment in the Caatinga pioneer species Pityrocarpa moniliformis

Reserve mobilisation and metabolite utilisation were characterised during seed germination and seedling establishment in Pityrocarpa moniliformis, an endospermic legume from Caatinga. Seeds were germinated under controlled conditions for four days and seedlings were transferred to hydroponics and maintained at a greenhouse during four days. Samples were collected at distinct physiological stages and reserves, metabolites, and enzymatic activities were determined in different seedling parts. Galactomannans stored in the endosperm and non-reducing sugars accumulated in the cotyledons were mobilised from seed germination to hypocotyl emergence. During these processes, the accumulation of reducing sugars in the endosperm coincided with an increase in the starch content in the cotyledons and seedling axis, indicating that sugars released from galactomannans may have been utilised in starch biosynthesis. Starch and storage protein mobilisation in the cotyledons occurred later, from hypocotyl elongation to cotyledon expansion. Starch degradation possibly supported the accumulation of starch and soluble sugars in the root, while storage protein hydrolysis was associated with cotyledon greening and first leaf emergence. Accordingly, reserve mobilisation exhibits a biphasic pattern, enabling fast seedling establishment as a physiological strategy to ensure environmental colonisation.

“…Also, XG tends to be as emulsifying agent rather than stabilizing agent. Being as emulsifying agent is mainly affiliated with having surface activity, availability of hydrophobic compounds like protein in the structure and the value of viscosity (originated from molecular weight) (Bakhshy et al, 2019; Razavi & Alghooneh, 2020). Hydrophilic nature of biopolymer means that the biopolymer will construct bonds with water molecules.…”

Emulsifying and foaming aspects of samples containing three hydrocolloids (Gleditsia caspica (GG) galactomannan, xanthan gum (XG), and fenugreek galactomannan (FG)) were comprehensively investigated. By elevating the concentration of biopolymers, the values of emulsifying capacity, emulsion stability, zeta potential, and foaming stability were significantly raised. Contrarily, the values of foaming capacity, z‐average, and PDI were reduced. Among the utilized hydrocolloids, the samples containing FG especially when blended with XG had higher emulsifying capacity and emulsion stability values in comparison with other samples. Also, samples containing XG had higher foaming capacity and those containing FG had higher foaming stability values compared with other samples. The samples containing FG had higher zeta potential and lower z‐average and PDI values compared with other samples. Due to the obtained results, Gleditsia galactomannan could be considered as stabilizing agent in food formulations. Novelty impact statement Introducing new sources of hydrocolloids (in current research, galactomannan obtained from Gleditsia caspica seed) with appropriate emulsifying and foaming properties is known as vital issue for researchers in food industry. Also, using mixture of hydrocolloids especially when G. caspica galactomannan was used in formulation of emulsions resulted in improved emulsifying and foaming aspects particularly emulsifying capacity, emulsion stability, and foaming stability.
