Processing and Functional Behaviour of Low-Tannin Mesquite Gum

Macromolecular Dimensions and Mechanical Properties of Monolayer Films of Sonorean Mesquite Gum

“…Instead, the experimental evidence available to date, argues in favor that mesquite gum comprises predominantly individual loose proteoglycan domains. This hypothesis is consistent with differences in rheology, hydrodynamic molecular dimensions, and area per molecule adsorbed to a oil‐water interface when both materials have been subjected to similar test conditions 18,20,21. It is accepted that the complex heterogeneous and amphiphilic structure of gum arabic is central to its unique functionality and utilitarian value, namely as an emulsifier and stabilizer of citrus flavor based softdrinks 29,30.…”

“…Although the overall composition of carbohydrate domains of mesquite gum seems to be closely related to that of gum arabic, both materials can distinctively be distinguished by different sets of antibodies which specifically recognize non‐reducing chain termini of the peripheral chains,19 as well as by crossed immunoelectrophoresis 20. Besides, studies by electrophoresis with Yariv reagent embedded in the second dimension, have shown that AGPs from gum arabic differ from those of mesquite gum21 and other AGPs of wild tomato 22…”

Immunochemical, Structural and Functional Properties of Mesquite Gum Compared with Gum Arabic

“…This technology was tested for efficacy in reducing tannin contents of commercial mesquite gum (Goycoolea et al 1998). These trials were conducted on a benchtop ultrafiltration unit (20 1) fitted with hollow fiber polysulfone cartridge membranes of 10-and 50-kDa molecular weight cut-off (MWCO).…”

“…Tannin and Protein Elimination Figure 2a shows tannin concentrations of retentate samples of mesquite gum as a function of overall ultradiafiltration processing time (Goycoolea et al 1998). Inspection of the curves for the two processing regimes with membranes of different MWCO shows that, in both cases, tannins are removed as monotonic exponential functions of time, with no signs of discontinuities in the curves at the changes between the ultrafiltration and diafiltration washing processes.…”

“…polysaccharides in combination with a small amount of protein (< 7% w/w) (Dickinson, 1993;Goycoolea et al, 1998). Their special filmforming and emulsifying properties may arise from the presence of these small protein fractions.…”
