TL;DR: In this article, the effect of gum arabic concentration at 35, 40 and 45 % with inlet temperatures of 160, 170 and 180 °C on the physico-chemical, functional and thermal properties of honey powder enriched with aonla (Emblica officinalis) extract was studied.
Abstract: The research studied the effect of gum arabic concentration at 35, 40 and 45 % with inlet temperatures of 160, 170 and 180 °C on the physico-chemical, functional and thermal properties of honey powder enriched with aonla (Emblica officinalis. Gaertn) and basil (Ocimum sanctum) extract, wherein other parameters like concentration of aonla extract (8 %), basil extract (6 %) and feed rate (0.11 mL/s) were kept as constant. Powder recovery and glass transition temperature (Tg) showed significant increase with the increase in inlet temperatures. On the other hand hygroscopicity, tapped density, total phenolic content, antioxidant activity and vitamin C content showed inverse response to the increase in inlet temperatures. However powder recovery, Tg, total phenolic content, antioxidant activity and vitamin C content increased with the increase in concentration of gum arabic. On the basis of obtained results it can be concluded that honey powder with the concentration of 45 % gum arabic at 170 °C inlet temperature was found to be less hygroscopic with better powder recovery and overwhelming antioxidant properties.

TL;DR: In this article, the response surface methodology (RSM) was used to establish optimum conditions for Flaxseed Oil (FO), soy lecithin and xanthan gum to yield stable FOD and high Microencapsulation Efficiency (M.E).
Abstract: Response Surface Methodology (RSM) was used to establish optimum conditions for Flaxseed Oil (FO), soy lecithin and xanthan gum to yield stable Flaxseed Oil Droplet (FOD) and high Microencapsulation Efficiency (M.E.E). Gum arabic and maltodextrin were used at constant ratio of 1:1 . Flaxseed oil loading (20-35%), lecithin (1-2%) and xanthan gum (0.1-0.4%) were studied regarding their effects on emulsion and the spray dried powder. Results indicated response surface models significantly fitted to all response variables studied. Regression models describing variations of responses of FOD and M.E.E showed high coefficient of determination (R ) of 0.9963 and 0.9944 respectively. Overall numerical 2 optimization predicted desirable system attainable by combined 10% (w/w) each arabic gum and maltodextrins, 22.78% (w/w) flaxseed oil loading, 1.14% (w/w) soy lecithin and 0.10% (w/w) xanthan gum, which in turn resulted into FOD of 446.9 nm, M.E.E of 92.3% and strong physical barrier towards oxidation during 10 weeks of storage tests.

TL;DR: It was concluded that the stability of β-carotene in oil-in-water emulsions could be improved by the presence of different antioxidants.
Abstract: The potential of oil-in-water emulsions as a β-carotene delivery system was examined in this study. Oil-in-water (O/W) emulsions containing β-carotene were formed by gum arabic with α-tocopherol, tertiary butyl hydroquinone (TBHQ) and ascorbyl palmitate, respectively. The influence of antioxidants on the chemical degradation of β-carotene in gum arabic stabilized emulsions was investigated at 4, 25, 45 and 65 °C in the dark, respectively. An accelerated photo-oxidation test was carried out at 45 °C (450 W/m2). Moreover, β-carotene degradation rate constants (k 1-value), activation energy (E a ) and decimal reduction time (D-value) were estimated to interpret the degradation kinetics. The impact of antioxidants on the thermal stability of β-carotene in diluted emulsions was generally in the following order: α-tocopherol > TBHQ > ascorbyl palmitate. α-Tocopherol was found to be the most effective to the antioxidation of β-carotene at the concentration of 0.10 wt% under light exposure. It was concluded that the stability of β-carotene in oil-in-water emulsions could be improved by the presence of different antioxidants.

TL;DR: The results showed that CS-Se°NPs had higher storage stability but easily aggregated in 500 mM NaCl or at pH > 8 because of their surface cationic groups, while the anionic groups in Cg-Se-NPs increased their resistant to pH variations and reduced cellular toxicity, and the multi-branched structure of GA-Se�NPsincreased their thermal stability.

TL;DR: In this article, the authors investigated the complex formation between sodium caseinate and gum arabic as a function of temperature using dynamic light scattering, fluorescence and NMR, and found that at neutral pH, the turbidity and particle size increased when the mixture was heated in situ at temperatures above a critical temperature.
