TL;DR: ZnS quantum dots (QDs), prepared by soft-condensation, exhibit robust structure of a quantum size equal 3.13 nm mediated two-dimensional gum Arabic surfactant as characterized by scan tunnelling microscope (STM) as mentioned in this paper.
Abstract: ZnS quantum dots (QDs), prepared by soft-condensation, exhibit robust structure of a quantum size equal 3.13 nm mediated two-dimensional gum Arabic surfactant as characterized by scan tunnelling microscope (STM). Strong blue-shifted absorption and emission bands are depicted by optical characterization even for the sample stored under ambient condition for two weeks. These enhancements can be attributed to the completely passivated surface trap states by Gum Arabic.

TL;DR: In this article, the authors used Completely Randomized Design (CRD) with five treatments and three replications followed by DNMRT test at 5% level to obtain the best concentration ratio of stabilizer CMC and gum arabic in making of avocado velva.
Abstract: The purpose of this research to obtain the best concentration ratio of stabilizer CMC and gum arabic in making of avocado velva. This research used Completely Randomized Design (CRD) with five treatments and three replications followed by DNMRT test at 5% level. The treatments in this research was CG1(stabilizer CMC:arabic gum=0:1), CG2 (stabilizer CMC:arabic gum= 1:2), CG3 (stabilizer CMC:arabic gum= 1:1), CG4 (stabilizer CMC:arabic gum= 2:1) dan CG5 (stabilizer CMC:arabic gum=1:0). The result of analyis of variance showed that variations combination of stabilizer CMC and gum arabic has significantly affected the overrun, melting rate, total dissolved solid and sensory value on descriptive and hedonic attribute texture. Variations ratio of stabilizer CMC and gum arabic on descriptive and hedonic did not significantly affected attribute colour, flavour and taste of avocado velva. The best treatment in this research was CG4 (stabilizer CMC:arabic gum= 2:1) with overrun 20.30%, melting rate 24.19 minutes, total dissolved solid 32.12 °brix, yellow colour, avocado flavour, avocado taste and soft texture.

TL;DR: In this article, the phenolic compounds of Satureja khuzistanica Jamzad (SKH) and S. rechingeri (SRH) were enriched based on adsorbent resin column chromatography and the enrichment index was confirmed by HPLC-UV analysis.
Abstract: Background: Phenolic compounds are one of the main groups of secondary metabolites responsible for multiple biological and pharmacological properties that play a vital role in improving human health quality. Encapsulation by spray dryer creates protection toward the phenolic compounds as an efficient way for increasing product performance. Method: The phenolic compounds of Satureja khuzistanica Jamzad (SKH) and S. rechingeri Jamzad (SRH) were enriched based on adsorbent resin column chromatography and the enrichment index was confirmed by HPLC-UV analysis. Gum Arabic, carboxylated chitosan, and pectin with the optimum percentage of 1% w/w used to encapsulate SKH and SRH by the spray drying technique. Result: Encapsulation yield was 38.18 – 59.00 %, particle size ranged 2.278 - 4.689 µm, and release time was between 4.08 - 82.08 min. The gum Arabic-based capsules showed the fastest and pectin-based revealed the slowest release time. The best statistical model explained a release mechanism was Korsmeyer model. Anomalous transport was observed from all formulas except SKH-gum Arabic (case-I transport), SKH-pectin, and SRH-carboxylated-chitosan (super case-II transport). The cytotoxic activity of encapsulate SKH’s revealed reducing the viability of AGS evaluated by the MTT compared with SRH’s. Conclusion: Encapsulation by spray drying has proven to be a promising technique to improve the bioavailability, release time, and mechanism of functional polyphenolic compounds as medicines, food supplements, and food additives.

TL;DR: In this paper, the authors proposed a slightly acidic low-viscosity milky beverage which contains 0.01-1 wt.% of pectin, 0.05-3 wt% of gum arabic and 0.1-8 wt%.
Abstract: PROBLEM TO BE SOLVED: To provide a novel slightly acidic low-viscosity milky beverage which does not lose stability and maintains favorable flavor even after long preservation. SOLUTION: This slightly acidic low-viscosity milky beverage contains 0.01-1 wt.% of pectin, 0.05-3 wt.% of gum arabic and 0.01-1 wt.% of a citrate as stabilizers, and has pH 4.6-5.4, viscosity of ≤20mPa s and a solid concentration of milk protein of 0.1-8 wt.%. The milky beverage having the above formulation and properties, is sterilized with heat, and has no coagulation of protein. COPYRIGHT: (C)2005,JPO&NCIPI

TL;DR: A dietary fiber composition containing Amorphophallus konjac as an ingredient for an easy-to-take functional food, a controlled-release drug or the like, and it can be obtained by adding and mixing water in one or more members selected from polysaccharide thickeners consisting of Amorphphallus Konjac, seed coat of Plantago ovata (psyllium), carrageenan, xanthan gum, curdlan, pectin, gum Arabic and pullulan and an inclusion agent which suppresses a water
Abstract: It is intended to provide a dietary fiber composition containing Amorphophallus konjac as an ingredient for an easy-to-take functional food, a controlled-release drug or the like, and it is obtained by adding and mixing water in Amorphophallus konjac with an average molecular weight of 50,000 or more purified using an alcohol from a matter in which starch is separated and removed from a tuber of Amorphophallus konjac plant and an inclusion agent which suppresses a water-absorbing property of Amorphophallus konjac. Further, it can also be obtained by adding and mixing water in one or more members selected from polysaccharide thickeners consisting of Amorphophallus konjac, seed coat of Plantago ovata (psyllium), carrageenan, xanthan gum, curdlan, pectin, gum Arabic, chitin, chitosan, guar gum, gellan gum, tara gum, tamarind gum, tragacanth gum and pullulan and an inclusion agent which suppresses a water-absorbing property of the polysaccharide thickeners.
