TL;DR: Gum sensitization is shown to be an increasing risk for predisposed individuals, especially through occupational contact, as demonstrated in hairdressers, confectioners, printers, employees of gum plants, and other workers who are subject to prolonged exposure.

TL;DR: In this article, the authors investigated the spray-drying process of turmeric oleoresin microencapsulated with binary and ternary mixtures of different wall materials: gum Arabic, maltodextrin, and modified corn starch.
Abstract: Spray-drying is a suitable method to obtain microencapsulated active substances in the powdered form, resulting in powders with improved protection against environmental factors as well as with higher solubility in water, as in the case of turmeric oleoresin. The present study investigated the spray-drying process of turmeric oleoresin microencapsulated with binary and ternary mixtures of different wall materials: gum Arabic, maltodextrin, and modified corn starch. A statistical simplex centroid experimental design was used considering the encapsulation efficiency, curcumin retention, process yield, water content, solubility, and particle morphology as the analyzed responses. Wall matrices containing higher proportions of modified starch and gum Arabic resulted in higher encapsulation efficiency and curcumin retention, whereas the process yield and water content increased with higher proportions of maltodextrin and gum Arabic, respectively. Regression models of the responses were obtained using a surface response method (ANOVA way), showing statistical values of R2 > 0.790. Also, mean analysis was carried out by Tukey's test, permitting to observe some statistical differences between the blends

TL;DR: The resulting sorbent HSGUM has been demonstrated efficient and the maximum boron sorption capacity at monolayer coverage (qmax) was found as average 4.10 mmol g-1.5mol, indicating good adsorption performance.

TL;DR: In this paper, the gum exudates from Acacia fischeri, A.kamerunensis and A.stenocarpa (all African species from Bentham's Section Gummiferae) have been completely characterized in terms of their carbohydrate and amino acid components.

TL;DR: Gum arabic, the natural exudate from Acacia senegal (L.) Willd.
Abstract: Gum arabic, the natural exudate from Acacia senegal (L.) Willd., has enjoyed the toxicological status ‘ADI not specified’ for use in minor proportions as a food additive (E414 in the EEC) since 1982, but it is also used as a major ingredient. Manufacturers may therefore be required to make labelling declarations of its Energy Value and of available/non-available carbohydrate. Although gum arabic complies with the definition for soluble dietary fibre, its Energy Value was accepted by the FAO/WHO International Programme of Food Safety to be 4 kcal/gram on the basis of the evidence available in 1982. Subsequently a French claim for a much lower value attracted the attention of manufacturers of low calorie products but a recent precise experiment establishes that the Digestible Energy Value is 3.5 ± 0.12 kilocalories per gram. The physiological mechanism whereby this value arieses is outlined. The more general dietary implications for other complex carbohydrates which conform to the definition for soluble dietary fibre and yet suffer complete degradation in the large bowel are indicated.
