TL;DR: In this article, the emulsions stabilized by gum Arabic (GA), OSE and HOSE starches were systematically compared in terms of molecular structure and emulsion properties, showing that the GA had a relative smaller molecular size distribution compared to OSE, and produced the small droplets with better storage stability, particularly at relatively low emulsifier concentrations.

TL;DR: In this article, the effects of different protective agents, such as high maize starch (HM), maltodextrin (MD), and gum arabic (GA), on the viability of Lactobacillus acidophilus after spray drying and during storage at different conditions were investigated.
Abstract: The effects of different protective agents, high maize starch (HM), maltodextrin (MD), and gum arabic (GA) on the viability of Lactobacillus acidophilus after spray drying and during storage at different conditions were investigated. Also, the physicochemical properties of the spray dried powders were evaluated. Lactobacillus acidophilus NRRL B-4495 (LA) was suspended in a 20% w/v solution of HM, MD, or GA. The solutions were separately spray dried at 140 °C to obtain LA powders: LAHM, LAMD, and LAGA. The powders were separately placed in aluminum bags and packed under 97 and 10% vacuum. The powders were stored at refrigerated (4 °C) and at room (23 °C) temperatures for 60 days. The moisture content of LA powders ranged from 5.63 to 8.98% with the LAMD powders showing lower moisture content than LAGA and LAHM powders. More than 6 log CFU/g of LA/g powder survived at 4 °C at 60 days of storage. LAGA and LAMD powders packed under 97% vacuum and stored at 4 °C had significantly higher cell viability than other powders. The study demonstrated that viability of LA powders packed under 97% vacuum and stored at refrigerated temperature meets the recommended levels to have therapeutic effects.

TL;DR: In this article, the authors attempted the encapsulation of lemongrass (Cymbopogon citratus) essential oil utilizing spray drying technique, and the results showed that the use of sole maltodextrin as encapsulant gave microcapsules characteristics comparable to that of powder produced using maltodesxtrin and gum Arabic mixture.
Abstract: The purpose of this study was to attempt the encapsulation of lemongrass (Cymbopogon citratus) essential oil utilizing spray drying technique. An array of process parameters including concentration of wall (15–30%), type of wall materials (maltodextrin, maltodextrin and gum Arabic mixture), and concentration of essential oil (0.5–2.0%) were thoroughly investigated. The results show that the use of sole maltodextrin as encapsulant gave microcapsules characteristics comparable to that of powder produced using maltodextrin and gum Arabic mixture. The encapsulation process that was performed with maltodextrin at the concentration of 30% as wall material and lemongrass essential oil at the concentration of 1.5% as core material showed highest drying yield (84.49%), microencapsulation yield (89.31%) and microencapsulation efficiency (84.75%). Encapsulated essential oils retained most of their major constituents in comparison with the bare essential oils without any significant compromise in product quality.

TL;DR: In this paper, an inventive biologically active ingredient carrier granule that adheres to the surface of plants, grasses, and weeds using a moisture-active coating was provided, illustratively including gum Arabic, guar gum, gum karaya, gum tragacanth and locust bean gum.
Abstract: A composition is provided that includes an inventive biologically active ingredient carrier granule that adheres to the surface of plants, grasses, and weeds using a moisture-active coating, illustratively including gum Arabic, guar gum, gum karaya, gum tragacanth and locust bean gum. Upon application of the inventive granule onto a plant surface, water from precipitation, irrigation, dew, co-application with the granules from special application equipment, or guttation water from the plant itself, provides sufficient moisture for adherence of the granule to the plant surface.
