Classification and physicochemical characterization of mesquite gum (Prosopis spp.)

Development of Nano-Emulsions of Essential Citrus Oil Stabilized with Mesquite Gum

“…Therefore, it follows that the different mesquite gums produced (oven dried procedure, dense lyophilized and controlled Lyophilized) essentially have the same chemical composition in terms of sugars, amino acids and proteins. Absorbance of the ▬OH and ▬CH groups are observed at 3375 and 2932 cm −1 (similar to that reported in the literature [17]), and a band centered between 1650 and 1600 cm −1 that can be assigned to the primary amides. There is a smaller band around 1500 cm −1 that is assigned to the secondary or substituted amides.…”

“…To carry out this analysis, the Thermo Nicolet 6700 FT-IR spectrophotometer with its attenuated total reflectance accessory (Thermo Scientific) was used, using solid samples (powders). Figure 5 shows the FT-IR spectra of the different gums characterized in this research, which are largely comparable with the FT-IR spectrum of Arabic gum (GA) reported in the literature [17,18]. Therefore, it follows that the different mesquite gums produced (oven dried procedure, dense lyophilized and controlled Lyophilized) essentially have the same chemical composition in terms of sugars, amino acids and proteins.…”

“…This gum is composed of a highly tailored polysaccharide salt, constituted by residues of L-arabinose, D-galactose, 4-O-Methyl-D-glucuronic acid and L-rhamnose (Figure 3) [15,16]. Mesquite gum chemical composition is similar (different molar ratio) to that one of Arabic gum, which is commonly employed in the food and pharmaceutical industry, due its emulsification capacity [17,18]. In México, mesquite gum is only consumed as a candy, therefore there is a wield field for exploration of this product as emulsifier.…”

“…Mesquite gum was extracted from mesquite pearls obtained from a local candy store at Sonora (Sonora, México). The purification process of the mesquite gum begins with the selection of the cleanest pearls by visual inspection as indicated by literature [17]; afterwards the pearls were ground in a ceramic mortar until a powder was obtained. Then a 20% (wt) solution of this powder was prepared, which was filtered (in order to eliminate impurities like dust and pieces of wood), details of the process can be found in literature [12].…”

Mesquite Gum as a Novel Reducing and Stabilizing Agent for Modified Tollens Synthesis of Highly Concentrated Ag Nanoparticles

“…COO − asymmetric stretching bands located at 1416 cm −1 were also identified. The bands around 1150 cm −1 and 900 cm −1 can be attributed to vibration modes of C–O and the C–O–H groups of carbohydrates (such as glucose, mannose and galactose), according to the literature [31,52,53,54]. The bands at 834 and 776 cm −1 indicate the occurrence of pyranose glycosidic acetal groups [54].…”
