“…Durian seed gum had a relatively high content of moisture (20.5-26.8%) in both crude and purified forms (Table 2). This value was greater than the moisture content reported for corn fiber gum (4.0-5.9%) [22], guar gum (7.36%), locust bean gum (7.92%), and gum karaya (9.43%) [23], acacia glomerosa gum (11.29) [24], grewia gum (10.6- 18.8) [25], and Baobab leaves gum (7.8-8.0) [26] (Table 3). …”

BackgroundThe biological functions of natural biopolymers from plant sources depend on their chemical composition and molecular structure. In addition, the extraction and further processing conditions significantly influence the chemical and molecular structure of the plant biopolymer. The main objective of the present study was to characterize the chemical and molecular structure of a natural biopolymer from Durio zibethinus seed. A size-exclusion chromatography coupled to multi angle laser light-scattering (SEC-MALS) was applied to analyze the molecular weight (Mw), number average molecular weight (Mn), and polydispersity index (Mw/Mn).ResultsThe most abundant monosaccharide in the carbohydrate composition of durian seed gum were galactose (48.6-59.9%), glucose (37.1-45.1%), arabinose (0.58-3.41%), and xylose (0.3-3.21%). The predominant fatty acid of the lipid fraction from the durian seed gum were palmitic acid (C16:0), palmitoleic acid (C16:1), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic acid (C18:2). The most abundant amino acids of durian seed gum were: leucine (30.9-37.3%), lysine (6.04-8.36%), aspartic acid (6.10-7.19%), glycine (6.07-7.42%), alanine (5.24-6.14%), glutamic acid (5.57-7.09%), valine (4.5-5.50%), proline (3.87-4.81%), serine (4.39-5.18%), threonine (3.44-6.50%), isoleucine (3.30-4.07%), and phenylalanine (3.11-9.04%).ConclusionThe presence of essential amino acids in the chemical structure of durian seed gum reinforces its nutritional value.

“…The depolymerization of polysaccharides upon irradiation has previously been reported. King and Gray () studied the similar effect of gamma irradiation on guar gum, locust bean gum, gum tragacanth, and gum karaya, where extraction of the soluble fraction increased with increasing irradiation dose. Corn and potato starch also followed similar behavior upon X‐ray and electron‐beam irradiation (De Kerf and others ).…”

Gamma irradiation was applied to the improved extraction of water-soluble polysaccharides (WSPs) from dried Lentinus edodes. Irradiation provided a dose-dependent increase in extraction yield (0 kGy, 2.01%; 7.5 kGy, 4.03%; 15 kGy, 7.17%) and purity (0 kGy, 78.8%; 7.5 kGy, 83.1%; 15 kGy, 85.6%) of the WSPs from hot-water extraction. The effect of irradiation was evident in the degraded microstructures and reduced molecular weights of the WSPs. However, nuclear magnetic resonance, Fourier-transform infrared, and X-ray diffraction spectroscopic analyses provided comparable structures of WSPs from nonirradiated and irradiated samples. UV-visible spectra showed a dose-dependent decline in intensity, but an improvement in thermal properties of the WSPs from the irradiated mushroom samples was observed.

“…Its more outstanding characteristics, however, are its high degree of stability under strong acid conditions and its use as a bifunctional stabiliser [17]. Previous studies have researched the effect of gamma irradiation on the viscosity of GT with unknown botanical sources [18,19]. However, to the best of our knowledge there is no report on how the structure and viscoelastic properties of GT dispersions are influenced by gamma irradiation.…”
