Isik, U. published the artcileFrozen yogurt with added inulin and isomalt, Synthetic Route of 64519-82-0, the main research area is freezing yogurt food formulation inulin isomalt.

The objective of this study was to produce a frozen yogurt containing low fat and no added sugar. Samples containing 5% polydextrose, 0.065% aspartame and acesulfame-K mixture, and different levels of inulin and isomalt (5.0, 6.5, and 8.0%) were produced at pilot scale and analyzed for their phys. and chem. properties including proximate composition, viscosity, acidity, overrun, melting rate, heat shock stability, as well as sensory characteristics, and viability of lactic acid bacteria. With the addition of inulin and isomalt, viscosity increased by 19 to 52% compared with that of sample B (reduced-fat control). The average calorie values of samples substituted with sweeteners were about 43% lower than that of original sample. Low-calorie frozen yogurt samples melted about 33 to 48% slower than the reduced-fat control sample at 45 min. Based on quant. descriptive profile test results, statistically significant differences among products were observed for hardness, iciness, foamy melting, whey separation, and sweetness characteristics. The results of principal component anal. showed that the sensory properties of the sample containing 6.5% inulin and 6.5% isomalt were similar to those of control. Lactic acid bacteria counts of frozen yogurt were found to be between 8.12 and 8.49 log values, 3 mo after the production The overall results showed that it is possible to produce an attractive frozen yogurt product with the incorporation of inulin and isomalt with no added sugar and reduced fat.

Zyzelewicz, Dorota published the artcileEffect of milk chocolate supplementation with lyophilised Lactobacillus cells on its attributes, Category: alcohols-buliding-blocks, the main research area is milk chocolate probiotic Lactobacillus sweetener functional food.

Manufacturing of novel foodstuffs supplemented with live probiotic bacteria has recently been intensively investigated. The supplementation of confectionery with probiotics is troublesome since some unit technol. processes are conducted at high temperatures and the products are usually stored at ambient temperature Our group has developed a method of the production of milk chocolate, sweetened with either sucrose or isomalt and aspartame, containing 32, 36, or 40 g/100 g fat, and supplemented with live cells of probiotic bacterial strains: Lactobacillus casei and paracasei. This new milk chocolate displayed the same sensory properties as the reference, probiotic-free chocolate. The number of live bacterial cells was maintained at the functional level of 106 ÷ 108 CFU/g after keeping for 12 mo irresp. of the temperature The highest number of live probiotic bacteria survived in the chocolate kept at 4°C. Thus the product can be regarded as functional food.

Jia, Hong-xin published the artcileThe stability of milk-based infant formulas during accelerated storage, Quality Control of 584-02-1, the main research area is milk infant formula fatty acid food storage.

The stability of milk-based formulas (infant formula and follow-up formula) were evaluated at 42°C and 50°C, during 90 days. Unsaturated fatty acids, color, peroxide values, headspace oxygen and volatile organic compounds (VOCs) were analyzed to evaluate the stability of milk-based formulas. No significant changes were observed in the unsaturated fatty acids (except DHA with a significant decrease after 90 days storage) of milk-based formulas stored at 42 or 50°C for 90 days. There is a significant change in color of the formulas during storage. For peroxide values and headspace oxygen, samples which were stored at a higher temperature would have higher peroxide values and less headspace oxygen after 90 days. For VOCs, results showed the significant differences of VOCs profiles in the formulas stored at different temperatures and lengths of storage period. In this study, the higher fat, the less oxidation stability was found.

Brown, Alistair K. published the artcileValidated quantitative cannabis profiling for Canadian regulatory compliance – Cannabinoids, aflatoxins, and terpenes, Application In Synthesis of 124-76-5, the main research area is cannabinoid aflatoxin terpene determination LC MS cannabis; Aflatoxins; Cannabis; Chromatography; Mass spectrometry; Quantitative method; Terpenes.

In response to the Canadian federal government’s Cannabis Tracking and Licensing System compliance standards, a quant. method was created for cannabis anal., and validated using Eurachem V.2 (2014) guidelines. Cannabinol, cannabidiol, cannabigerol, cannabichromene, cannabidiolic acid, cannabigerolic acid, Δ-9-tetrahydrocannabinol, and Δ-9-tetrahydrocannabinolic acid A were all analyzed by scheduled multiple reaction monitoring (MRM) via LC-MS/MS and isotope dilution In addition, aflatoxins B1, B2, G1, and G2 were also analyzed by scheduled MRM via LC-MS/MS and matrix matched calibration curves to achieve the reporting limits (≤2μg kg-1) set out by the European Pharmacopoeia. The LODs/LOQs were 0.50/1.7, 2.0/6.7, 0.59/2.0, and 0.53/1.8μg kg-1, for B1, B2, G1, and G2 resp. Thirty one terpenes were analyzed by selected reaction monitoring via GC-MS/MS and isotope dilution using β-myrcene-d6 as a surrogate. All quant. analyses can be accomplished using less than 1 g of material, with minimal solvent and consumable use, on low resolution instruments in less than 30 min of instrument time. Of important note is this method’s power of selectivity, working ranges, and lack of need for extraction consumables such as SPE or QuEChERS, thereby minimising anal. costs and time.

Rich, Jamie R. published the artcileChemical and chemoenzymatic synthesis of S-linked ganglioside analogs and their protein conjugates for use as immunogens, Category: alcohols-buliding-blocks, the main research area is Tetanus toxoid bovine serum albumin protein antigen vaccine immunogen; glycoprotein ganglioside synthesis coupling glycosyltransferase catalyzed immunogen glycosylation vaccine; hydrolase resistance glycoside antigen thioglycosidic linkage immunogenic antibody oligosaccharide; neuraminic acid ganglioside coupling disaccharide sphingosine glycosyltransferase catalyzed trisaccharide; sialic acid chemoenzymic synthesis ganglioside protein conjugate immunogen disaccharide.

Analogs of the tumor-associated gangliosides GM3 and GM2 containing terminal S-linked neuraminic acid residues and an amino terminated, truncated ceramide homolog have been synthesized and conjugated to a protein. The synthesis involved coupling of a S-linked sialyl α(2→3) galactose disaccharide with a glucosyl sphingosine analog, followed by elaboration and deprotection to give amino-terminated glycosyl ceramide. Glycosyltransferase-catalyzed extension of the trisaccharide provided access to the modified GM2 tetrasaccharide or sulfur-containing GD3 analog. Owing to their potentially enhanced resistance to endogenous exo-glycoside hydrolases and their inherent non-self character, carbohydrate antigens containing non-reducing terminal thioglycosidic linkages may be more immunogenic than O-linked antigens and may stimulate the production of antibodies capable of recognizing naturally occurring oligosaccharides. Our initial results suggest that in fact these antigens are viable immunogens and furthermore, that immune sera cross reacts with O-gangliosides in the context of a heterologous glycoprotein conjugate.

Rontani, J.-F. published the artcileOrigin and degradation of lipids in aeolian particles from a coastal area of the north-western Mediterranean Sea, Synthetic Route of 13099-34-8, the main research area is coastal area aeolian particle lipid degradation Mediterranean Sea.

The lipid content of eight samples of aeolian particles collected on the Frioul Islands (north-western Mediterranean Sea) during the year 2010 was investigated. Lipid analyses indicated a significant contribution of terrestrial higher plant debris to some of the samples, while meat cooking residues were also found. Specific degradation products of sterols and monounsaturated fatty acids were employed to assess the importance of biotic and abiotic degradation processes on land and during aeolian transport. Degradation of higher plant lipids on land appears to involve Type II (i.e., singlet oxygen-mediated) photooxidation during senescence and bacterial degradation processes in soils, while during aeolian transport this terrestrial material mainly undergoes autoxidation and/or Type I (i.e., radical-mediated) photooxidation and is relatively well preserved towards bacterial degradation In contrast, bacteria play a significant role in the degradation of meat cooking residues in these particles.

Ghazali, Habibah published the artcileMicroencapsulated healing agents for an elevated-temperature cured epoxy: Influence of viscosity on healing efficiency, SDS of cas: 7575-23-7, the main research area is cured epoxy resin microencapsulated healing agent viscosity.

Elevated-temperature cured epoxy resins are widely used for high-performance applications especially for structural adhesive and as a matrix for structural composites. This is due to their superior chem. and mech. properties. The thermosetting nature of epoxy produces a highly crosslinked polymer network during the curing process where the resulting material exhibited excellent properties. However, due to this crosslinked mol. structure, epoxies are also known to be brittle, and once a crack initiated in the material, it is difficult to arrest the crack propagation. Earlier research found that the inclusion of encapsulated healing agents is able to introduce self-healing ability to the room-temperature cured epoxies. The current study investigated the self-healing behavior of an elevated-temperature cured epoxy, which incorporated the dual-capsule system loaded with bisphenol A diglycidyl ether (DGEBA) resin and mercaptan. The microcapsules were prepared by the in-situ polymerization method while the fracture toughness and the self-healing capability of the tapered-double-cantilever-beam (TDCB) epoxy specimens were measured under Mode-I fracture toughness testing. We investigated the effect of temperature on viscosity of the healing agents and how these values influence the formation of uniform healing on the fracture surfaces. It was found that incorporation of the dual-capsule self-healing onto an elevated-temperature cured epoxy slightly changed the fracture toughness of the epoxy as indicated by the Mode-I testing.

Mimata, Yoshiharu published the artcileExtracellular malate induces stomatal closure via direct activation of guard-cell anion channel SLAC1 and stimulation of Ca2+ signalling, Related Products of alcohols-buliding-blocks, the main research area is extracellular malate stomatal closure SLAC1 direct activation calcium signalling; Arabidopsis; Ca2+ signalling; SLAC1; malate; stomata.

Plants secrete malate from guard cells to apoplast under stress conditions and exogenous malate induces stomatal closure. Malate is considered an extracellular chem. signal of stomatal closure. However, the mol. mechanism of malate-induced stomatal closure is not fully elucidated. We investigated responses of stomatal aperture, ion channels, and cytosolic Ca2+ to malate. A treatment with malate induced stomatal closure in Arabidopsis thaliana wild-type plants, but not in the mutants deficient in the slow (S-type) anion channel gene SLOW ANION CHANNEL-Associated 1 (SLAC1). The treatment with malate increased S-type anion currents in guard-cell protoplasts of wild-type plants but not in the slac1 mutant. In addition, extracellular rather than intracellular application of malate increased the S-type currents of constitutively active mutants of SLAC1, which have kinase-independent activities, in a heterologous expression system using Xenopus oocytes. The treatment with malate transiently increased cytosolic Ca2+ concentration in the wild-type Arabidopsis guard cells and the malate-induced stomatal closure was inhibited by the Ca2+ channel blocker and the Ca2+ chelator. These results indicate that extracellular malate directly activates SLAC1 and simultaneously stimulates Ca2+ signalling in guard cells, resulting in steady and solid activation of SLAC1 for stomatal closure.
