Bertotto, Carlize published the artcileDevelopment of a biodegradable plastic film extruded with the addition of a Brazilian propolis by-product, Related Products of esters-buliding-blocks, the main research area is Brazilian propolis development biodegradable plastic film.

The development of new materials environmentally friendly has become an important market niche for the food industry. The agro-industrial wastes and byproducts can be an alternative for the production of biodegradable food packaging. The work aimed to produce biodegradable plastic film extruded with antioxidant and antibacterial properties by the joining of cassava starch and Brazilian propolis byproduct (BPB). The volatile profile of BPB, Brazilian propolis byproduct film (BPBF), and control film (CF) were analyzed by gas chromatog. The mech., antioxidant, and antibacterial properties of the films were also assessed. Eighty-seven volatile compounds were detected with aldehydes and terpenoids predominating in the samples. The major terpenoid detected in the samples was the 2-pinen-10-ol followed by α-copaene. Benzaldehyde and benzenepropanoic acid Et ester were the major aldehyde and ester classes present in the films. The BPBF exhibited promising mech. properties showing the highest Elasticity modulus (11.96 Mpa) and excellent antioxidant (8.45 mmol Trolox equivalent/g) and antibacterial (12.5 mg/mL against Staphylococcus aureus and Salmonella Typhimurium) activities. The valorization of agro-industrial byproducts following the current trends to environmental care can be a sustainable alternative for the development of a plastic into which the propolis byproduct is incorporated in biodegradable packaging.

Bashar, Hm khairul published the artcileDocumentation of Phytotoxic Compounds Existing in Parthenium hysterophorus L. Leaf and Their Phytotoxicity on Eleusine indica (L.) Gaertn. and Digitaria sanguinalis (L.) Scop, Category: esters-buliding-blocks, the main research area is caffeic ferulic acid Parthenium leaf Eleusine Digitaria phytotoxicity; allelochemicals; bioherbicides; caffeic acid; phytotoxicity; phytotoxins documentation.

The utilization of the invasive weed, Parthenium hysterophorus L. for producing value-added products is novel research for sustaining our environment. Therefore, the current study aims to document the phytotoxic compounds contained in the leaf of parthenium and to examine the phytotoxic effects of all those phytochems. on the seed sprouting and growth of Crabgrass Digitaria sanguinalis (L.) Scop. and Goosegrass Eleusine indica (L.) Gaertn. The phytotoxic substances of the methanol extract of the P. hysterophorus leaf were analyzed by LC-ESI-QTOF-MS=MS. From the LC-MS study, many compounds, such as terpenoids, flavonoids, amino acids, pseudo guaianolides, and carbohydrate and phenolic acids, were identified. Among them, seven potential phytotoxic compounds (i.e., caffeic acid, vanillic acid, ferulic acid, chlorogenic acid, quinic acid, anisic acid, and parthenin) were documented, those are responsible for plant growth inhibition. The concentration needed to reach 50% growth inhibition in respect to germination (ECg50), root length (ECr50), and shoot length (ECs50) was estimated and the severity of phytotoxicity of the biochems. was determined by the pooled values (rank value) of three inhibition parameters. The highest growth inhibition was demarcated by caffeic acid, which was confirmed and indicated by cluster anal. and principal component anal. (PCA). In the case of D. sanguinalis, the germination was reduced by 60.02%, root length was reduced by 76.49%, and shoot length was reduced by 71.14% when the chem. was applied at 800 μM concentration, but in the case of E. indica, 100% reduction of seed germination, root length, and shoot length reduction occurred at the same concentration The lowest rank value was observed from caffeic acids in both E. indica (rank value 684.7) and D. sanguinalis (909.5) caused by parthenin. It means that caffeic acid showed the highest phytotoxicity. As a result, there is a significant chance that the parthenium weed will be used to create bioherbicides in the future.

Corona, Onofrio published the artcileQuality and volatile compounds in red wine at different degrees of dealcoholization by membrane process, Computed Properties of 5405-41-4, the main research area is red wine volatile compound phenol sensory property dealcoholization.

This study investigated the effect of different degrees of dealcoholization on volatile compounds, phenols and sensory characteristics of red wine (cv. Montepulciano d’Abruzzo). The wine with an initial alc. content of 13.2% volume/volume was partially dealcoholized by membrane process with a decrease of alc. degree as follows: – 4.9; – 6.3; – 7.8, – 9.2 and – 10.5% volume/volume Osmotic distillation has proved effective in preserving a satisfactory odorous profile, as samples with an alc. residue of 8.3% volume/volume (- 4.9%) and 6.9% volume/volume (- 6.3%) showed good esters retention more than 84% and 82%, resp. Similarly, color and taste, evaluated by flavonoids and phenolic compounds, remained almost unchanged in all dealcoholized samples. Lastly, the trials highlighted that dealcoholized wine up to an alc. content of about 5.4% volume/volume (- 7.8%) was still perceived as acceptable by the tasters.

Hadj Saadoun, Jasmine published the artcileProduction and recovery of volatile compounds from fermented fruit by-products with Lacticaseibacillus rhamnosus, Quality Control of 5405-41-4, the main research area is Lacticaseibacillus Cucumis Citrus fermentation volatile compound.

In the last years, due to the increasing interest of consumers in natural products, market and industry choices were more directed towards the use of fragrances and flavors obtained from natural sources. Fermentation is a biol. approach helpful to produce diverse aromatic compounds modifying precursors present in raw material, due to a wide array of extracellular enzymes which could be produced by microorganisms. Following this direction Lacticaseibacillus rhamnosus was employed as a starter for melon and orange byproducts fermentation Simple and vacuum distillation were applied for the recovery of the aromatic fraction and compared to identify the more promising in terms of aromatic profile composition Detection and characterization of aromatic compounds were achieved using Head SpaceSolid Phase MicroExtn. Gas Chromatog.-Mass Spectrometry (HS-SPME/GC-MS) approach. Fermentation led to interesting changes, increasing floral, herbal green and fruity notes. Overall, simple distillation allowed the greater recovery of aromatic compounds in terms of concentration for both substrates. This study highlights a possible strategy to produce complex distillates, composed of a mixture of aroma compounds, to be employed as additives in food, feed or perfumery industries as ingredients of natural origin.

Li, Hong-Xing published the artcileA hydroxyl-functionalized homochiral porous organic cage for gas chromatographic separations, Computed Properties of 5405-41-4, the main research area is hydroxyl functionalized homochiral porous organic cage gas chromatog separation; Capillary column; Chiral separation; Chiral stationary phase; Gas chromatography; Porous organic cage; Positional isomers; Racemates.

A hydroxyl-functionalized homochiral porous organic cage (POC) was synthesized and characterized by FTIR, NMR, thermogravimetric anal. (TGA), MALDI-TOF-MS, and elemental anal. The synthesized homochiral POC was used as stationary phase to prepare a capillary gas chromatog. (GC) column by a static coating method. The fabricated column shows excellent selectivity not only for the separation of positional isomers but also for the resolution of various racemates. Thirty-nine racemates have been resolved on the column, including alcs., diols, halohydrocarbons, epoxides, esters, lactones, ketones, ethers, and organic acids. Compared to the com. β-DEX 120 column and previously reported chiral POCs (CC3-R, CC9, and CC10)-coated columns, there are 11, 10, 24, and 15 tested racemates that cannot be resolved on β-DEX 120 column, CC3-R column, CC9 column, and CC10 column, resp. This reveals that the fabricated column has prominent complementarity or superior separation performance to these columns in enantioseparation Besides, the fabricated column can achieve some enantioseparations which are not possible using all previously reported chiral POC-based columns. Some positional isomers (xylenes, dichlorobenzenes, dibromobenzenes, nitrochlorobenzenes, and nitrobromobenzenes) were also separated with high-resolution values. The column exhibits good repeatability, reproducibility, and stability.
