And the article contained the following:

Unlike the conversion of monosaccharides to the corresponding polyols, the production of maltitol by hydrogenation of maltose has been seldom investigated in the literature, despite its industrial importance. Monometallic Ni catalysts are known for their lack of stability, and the objective of the present paper is to determine through a kinetic study, to what extent a Ni-Fe/SiO2 bimetallic catalyst would outperform a Ni/SiO2 catalyst in the aqueous phase hydrogenation of maltose. The effect of reaction parameters (T = 80-150°C, PH2 = 20-40 bar, maltose mass fraction in water = 4.4-17.5 wt%) on activity, selectivity, and stability was examined In all cases, maltitol was the major product, with a carbon balance higher than 98%, but maltose hydrolysis to glucose occurred in the upper range of temperature In order to preserve both the catalyst selectivity and stability, a temperature of 80°C was selected for the kinetic study. The adsorption constant of maltose and the apparent hydrogenation rate constant for the Ni-Fe catalyst were both larger by a factor 2-3 compared with the Ni catalyst, indicating a stronger interaction of maltose with the Ni-Fe surface. Another major difference was a reaction order of 0.5 with respect to the hydrogen pressure on Ni-Fe/SiO2 compared with a near zero-order on Ni/SiO2. The activity of the Ni-Fe catalyst remained constant for three runs of reaction without major structural changes, while the Ni catalyst deactivated by transforming to a phyllosilicate phase. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Application In Synthesis of SweetPearlR P300 DC Maltitol

On April 1, 2021, Yong, Yang; Gu, Huajun; Zhang, Qingxiao; Fang, Zhang; Hui, Li published an article.Application In Synthesis of SweetPearlR P300 DC Maltitol The title of the article was Hollow ni-p amorphous alloy nanospheres: An efficient catalyst for sugars hydrogenation to polyols. And the article contained the following:

In this paper, hollow Ni – P nanospheres (NSs) are prepared through Ni electroless plating on the Au-activated silica NSs externally covered by aminopropyl moieties, followed by removing the silica template with sodium hydroxide. With various characterizations, the resulting hollow Ni – P NSs are identified to be amorphous alloy. During liquid-phase hydrogenation of sugars to sugar alcs., the hollow Ni – P amorphous alloy NSs delivered much superior catalytic performances to the com. Raney Ni catalyst, showing a good potential in practical applications. Of particular interest is the unique hollow chamber structure of the hollow Ni – P amorphous alloy NSs, which allows for improving catalytic activity and durability relative to those associated with the dense Ni – P amorphous alloy NSs. This work demonstrated that such hollow Ni materials with nanoporous chamber structure displayed advantages such as easy exptl. handling and high accessibility for the reactants in liquid-phase reaction, more Ni active sites, as well as the existence of more electron-enriched inner surface, which is essential to provide highly efficient catalysts for some reactions.

On February 28, 2022, Polidoro, Daniele; Perosa, Alvise; Barbaro, Elena; Feltracco, Matteo; Argiriadis, Elena; Selva, Maurizio published an article.Name: SweetPearlR P300 DC Maltitol The title of the article was Multiphase Hydrogenation of D-Glucosamine Hydrochloride, N-Acetyl-D-Glucosamine, D-Glucose, and D-Maltose over Ru/C with Integrated Catalyst Recovery. And the article contained the following:

A multiphase (MP) system composed of two immiscible liquids, water and isooctane, and com. 5% Ru/C as a catalyst, both with and without an addnl. organic liquid (OL: THF, 2-methyl-THF, Me iso-Bu carbinol, and cyclopentyl Me ether) was designed and investigated for the chemoselective catalytic hydrogenation of four model examples of biobased sugars and amino/amido-sugars. At 110°C and 40 bar of H2, D-glucosamine hydrochloride and N-acetyl-D-glucosamine were converted selectively into their corresponding hydrogenated derivatives, 2-amino-D-sorbitol and 2-acetamide-D-sorbitol, resp., isolated in >99% yields. Both the reagents and the products were converted and formed in the aqueous phase, resp., while, by tuning the relative proportions of water, isooctane, and the third added liquid (particularly THF), the catalyst (Ru/C) was perfectly segregated in the organic layer, where it could be recycled and reused up to nine times without any loss of activity and selectivity, in a semicontinuous mode. Under such conditions, the reaction was implemented on a gram scale with a productivity up to 0.89 mmol 2-amino-D-sorbitol/(gcat h). The same hydrogenation efficiency and reagent/product/catalyst separation were achieved during the MP reactions of D-glucose and D-maltose. In this case, however, results were independent of the MP composition: at 120°C and 20-40 bar of H2, using either H2O/isooctane or H2O/isooctane/OL systems, a quant. conversion of D-glucose and D-maltose was reached with a selectivity up to 78 and >99% toward sorbitol and maltitol, resp. Ru/C was perfectly separated out of the aqueous phase in both MP mixtures, with a negligible metal leaching, below 0.01 weight %. The multiphase approach for all the tested substrates proved not only to be an original and robust protocol to improve the product isolation and catalyst recycling, but also effective in preventing metal contamination in the synthesis of final derivatives The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Name: SweetPearlR P300 DC Maltitol

And the article contained the following:

The formation of dendrites and low coulombic efficiency hinder the application of aqueous zinc ion batteries in large energy storage systems. As the electrolyte additive, maltitol is adsorbed on the zinc to regulate the anode interface. The maltitol inhibits the growth of zinc dendrites and improves the cycling stability of the zinc anode, which has been proven by a series of electrochem. approaches. The scanning electron microscope and the in situ optical microscope have recorded the smooth deposition of the zinc. The mechanism of interface regulation has been implemented by specific adsorption and deceleration kinetics, verified by XPS, Raman spectra, and DFT calculations The Zn//Zn sym. cells reached a stable plating/stripping performance over 1000 h at 2 mA cm-2 with 2 mA h cm-2. This cheap and eco-friendly additive provides an alternative for the application of aqueous zinc ion batteries.

Saraiva, Ariana; Carrascosa, Conrado; Raheem, Dele; Ramos, Fernando; Raposo, Ant Onio published an article in 2020, the title of the article was Maltitol: analytical determination methods, applications in the food industry, metabolism and health impacts.Computed Properties of 585-88-6 And the article contains the following content:

A review. Bulk sweetener maltitol belongs to the polyols family and there have been several dietary applications in the past few years, during which the food industry has used it in many food products: bakery and dairy products, chocolate, sweets. This review paper addresses and discusses in detail the most relevant aspects concerning the anal. methods employed to determine maltitol’s food safety and industry applications, its metabolism and its impacts on human health. According to our main research outcome, we can assume that maltitol at lower doses poses little risk to humans and is a good alternative to using sucrose. However, it causes diarrhoea and foetus complications at high doses. Regarding its determination, high-performance liquid chromatog. proved the primary method in various food matrixes. The future role of maltitol in the food industry is likely to become more relevant as processors seek alternative sweeteners in product formulation without compromising health.

On October 25, 2021, Macho, Oliver; Gabrisova, Ludmila; Brokesova, Jana; Svacinova, Petra; Muzikova, Jitka; Galbava, Paulina; Blasko, Jaroslav; Sklubalova, Zdenka published an article.Application of 585-88-6 The title of the article was Systematic study of paracetamol powder mixtures and granules tabletability: Key role of rheological properties and dynamic image analysis. And the article contained the following:

The aim of this systematic study was to analyze the granulometric and rheol. behavior of tableting mixtures in relation to tabletability by single tablet and lab-scale batch compression with an eccentric tablet machine. Three mixtures containing 33, 50, and 66% of the cohesive drug paracetamol were prepared The high compressibility of the powder mixtures caused problems with overcompaction or lamination in the single tablet compression method; due to jamming of the material during the filling of the die, the lab-scale batch compression was impossible. Using high shear granulation, the flow properties and tabletability were adjusted. A linear relationship between the span of granules and the specific energy measured by FT4 powder rheometer was detected. In parallel, a linear relationship between conditioned bulk d. and the tensile strength of the tablets at lab-scale batch tableting was noted. The combination of dynamic image anal. and powder rheometry was useful for predicting the tabletability of pharmaceutical mixtures during the single tablet (design) compression and the lab-scale batch compression.

Billy, Yin Sing O.; Coyle, Daisy H.; Dunford, Elizabeth K.; Wu, Jason H. Y.; Louie, Jimmy Chun Yu published an article in 2021, the title of the article was The use of non-nutritive and low-calorie sweeteners in 19,915 local and imported pre-packaged foods in Hong Kong.Product Details of 585-88-6 And the article contains the following content:

This study aims to examine the use of non-nutritive (NNSs) and low-calorie sweeteners (LCSs) in pre-packaged foods in Hong Kong and the differences in the number of NNSs/LCSs used between products from different regions. In a cross-sectional audit, the types of NNSs/LCSs used in 19,915 pre-packaged foods in Hong Kong were examined by searching the ingredients list of the included products for keywords related to 20 common NNSs/LCSs and their resp. E-numbers Prevalence of use of NNSs and LCSs, the co-presence of NNSs/LCSs and free sugar ingredients (FSI), and the number of NNSs/LCSs used in the included foods were computed. Pearson’s χ2 test was used to compare the total number of NNSs and/or LCSs used in food items from different regions. Sucralose (E955) was the most commonly used NNS (1.9%), followed by acesulfame K (E950, 1.6%). Sorbitol was the most commonly used LCS (2.9%). Overall, the use of LCSs was less common compared with NNSs (3.7% vs. 4.5%). The use of different types of NNSs varied substantially between food types. Notably, 20.2% of potato crisps and 15.2% of other crisps or extruded snacks contained at least one NNS and/or LCS. Co-presence of FSIs and NNSs/LCSs were most common in confectionery (15.7%) and snack foods (15.5%). Asian prepackaged foods were more likely to contain NNSs/LCSs (10.1%) compared with those from other regions. To conclude, NNSs/LCSs were used in a wide range of non-diet pre-packaged products which could be a public health concern due to their higher consumption frequencies than “diet” products.

Haewpetch, Patinya; Rudeekulthamrong, Prakarn; Kaulpiboon, Jarunee published an article in 2022, the title of the article was Enzymatic Synthesis of Maltitol and Its Inhibitory Effect on the Growth of Streptococcus mutans DMST 18777.Product Details of 585-88-6 And the article contains the following content:

This study aimed to synthesize maltitol using recombinant CGTase from Bacillus circulans A11 with β-cyclodextrin (β-CD) and sorbitol as a glucosyl donor and acceptor, resp., and assess its antibacterial activity. Optimal conditions for producing the highest yield, 25.0% (weight/weight), were incubation of 1% (w/v) β-CD and sorbitol with 400 U/mL of CGTase in 20 mM phosphate buffer at pH 6.0 and 50°C for 72 h. Subsequently, maltitol underwent large-scale production and was purified by HPLC. By mass spectrometry, the mol. weight of the synthesized maltitol was 379.08 daltons, corresponding exactly to that of standard maltitol. The relative sweetness of synthesized and standard maltitol was ~90% of that of sucrose. Spot assay on the agar plate showed that maltitol inhibited the growth of Streptococcus mutans DMST 18777 cells. In addition, the MIC and MBC values of synthesized and standard maltitol against S. mutans were also determined as 20 and 40 mg/mL, resp. These results show that the synthesized maltitol can be produced at high yields and has the potential to be used as an anticariogenic agent in products such as toothpaste.

On September 30, 2022, Li, Junnan; Li, Yannan; Duan, Wenzhe; Zhao, Zhonghui; Yang, Lixuan; Wei, Wei; Li, Jingchun; Li, Yang; Yu, Yao; Dai, Baoan; Guo, Rongjuan published an article.Category: alcohols-buliding-blocks The title of the article was Shugan granule contributes to the improvement of depression-like behaviors in chronic restraint stress-stimulated rats by altering gut microbiota. And the article contained the following:

The investigation aims to evaluate the potential effect of Shugan Granule (SGKL) on the gut, brain, and behaviors in rats exposed to chronic restraint stress (CRS). The fecal microbiota and metabolite changes were studied in rats exposed to CRS and treated with SGKL (0.1 mg/kg/day). Depressive behaviors of these rats were determined through an open-field experiment, forced swimming test, sucrose preference, and weighing. Moreover, LPS-stimulated microglia and CRS-stimulated rats were treated with SGKL to investigate the regulation between SGKL and the PI3K/Akt/pathway, which is inhibited by LY294002, a PI3K inhibitor. (I) SGKL improved the altered behaviors in CRS-stimulated rats; (ii) SGKL ameliorated the CRS-induced neuronal degeneration and tangled nerve fiber and also contributed to the recovery of intestinal barrier injury in these rats; (iii) SGKL inhibited the hippocampus elevations of TNF-α, IL-1β, and IL-6 in response to CRS modeling; (iv) based on the principal coordinates anal. (PCoA), SGKL altered α-diversity indexes and shifted β-diversity in CRS-stimulated rats; (v) at the genus level, SGKL decreased the CRS-enhanced abundance of Bacteroides; (vi) Butyricimonas and Candidatus Arthromitus were enriched in SGKL-treated rats; (vii) altered gut microbiota and metabolites were correlated with behaviors, inflammation, and PI3K/Akt/mTOR pathway; (viii) SGKL increased the LPS-decreased phosphorylation of the PI3K/Akt/mTOR pathway in microglia and inhibited the LPS-induced microglial activation; (ix) PI3K/Akt/mTOR pathway inactivation reversed the SGKL effects in CRS rats. SGKL targets the PI3K/Akt/mTOR pathway by altering gut microbiota and metabolites, which ameliorates altered behavior and inflammation in the hippocampus.
