Marakis, Georgios published the artcileFatty acid profile of processed foods in Greece with focus on trans fatty acids, Computed Properties of 110-42-9, the main research area is trans fatty acid processed food.

Abstract: The adverse health effects of trans fatty acids (TFA) are well recognized. The Commission Regulation (EU) 2019/649 specifies that foods should not contain more than 2 g of industrially produced TFA (i-TFA) per 100 g of fat. This study aimed to investigate the fatty acid profile, with focus on TFA and i-TFA, of foods widely consumed in Greece that are purported to contain high TFA concentrations Sweet and savoury (i.e. non-sweet), prepacked and non-prepacked (i.e. loose) processed foods (N = 140) were sampled. After lipid extraction, the fatty acid profile of each sample was determined by gas chromatog. Estimation of ruminant TFA (r-TFA) was based on butyric acid values. i-TFA was assessed after subtraction of r-TFA from total TFA. Both total and i-TFA contents of cakes, biscuits, croissants and doughnuts on average were low (< 2% of total fat), even though the saturated fat content of some products from these food groups was high. Pies and pastries made with puff and shortcrust pastry had the highest i-TFA content. About 15.7% of all samples had an i-TFA content that exceeded the 2% limit set in foods by the new Commission Regulation (EU) 2019/649. Meat products and French fries had i-TFA levels that did not exceed 1% of total fat. In view of the lack of data on TFA content of foods in Greece, these results highlight the necessity to improve their nutritional quality and provide guidance for planning future targeted inspections regarding the TFA content of foods.

Fiore, Alberto published the artcileActive packaging based on PLA and chitosan-caseinate enriched rosemary essential oil coating for fresh minced chicken breast application, Recommanded Product: Methyl decanoate, the main research area is chicken breast packaging rosemary essential oil PLA chitosan caseinate.

Active packaging systems are considered an effective way to prolong the shelf life of fresh food products. This study compared five different biopolymer films for their ability to delay the lipid oxidation of raw chicken meat. New antioxidant poly lactic acid film was prepared by coating the film surface with chitosan or chitosan/caseinate blend enriched with rosemary essential oil at concentration of 1% and 2%. Films were characterized in terms of microstructure, water vapor permeability, mech. properties, and antioxidant capacity. In vivo study was done using fresh minced chicken meats stored at 4 °C and analyzed after 0, 4, 7, 11, 14, 21 days. Results indicated that water vapor transmission rate was reduced by the presence of the coating and assumed the lowest value (1.23 ± 0.03 x 10-4 g m-2 s-1) with coating enriched with 2% of rosemary essential oils. The films showed an antioxidant capacity of maximum 6% equivalent to the antioxidant capacity of 6,25 μg of REO/mL. Results from in vivo test showed that the active films were able to reduce meat oxidation during storage in anaerobic modified atm. condition: samples packed with active film showed constant malondialdehyde (MDA) and color up to 14 days and reduction of heptanal and ethanol concentration compared to samples packed with control film (72 % and 90 % resp.). Overall, this study has demonstrated that PLA films coated with an active coating are a promising delivery method for providing antioxidant effects in packaging for fresh meat products.

Taviano, Maria Fernanda published the artcilePhytochemical Constituents, Antioxidant Activity, and Toxicity Assessment of the Aerial Part Extracts from the Infraspecific Taxa of Matthiola fruticulosa (Brassicaceae) Endemic to Sicily, Name: Methyl decanoate, the main research area is Matthiola extract phytochem antioxidant agent toxicity; Matthiola fruticulosa; Sicily; biological activity; chemical composition; native plants; natural resource.

In a project designed to investigate the specific and infraspecific taxa of Matthiola endemic to Sicily (Italy) as new potential sources of bioactive compounds in this work, the infraspecific taxa of Matthiola fruticulosa were studied, namely, subsp. fruticulosa and subsp. coronopifolia. HPLC-PDA/ESI-MS and SPME-GC/MS analyses of hydroalcoholic extracts obtained from the aerial parts of the two subspecies led to the detection of 51 phenolics and 61 volatile components, highlighting a quite different qual.-quant. profile. The antioxidant properties of the extracts were explored through in vitro methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH), reducing power and Fe2+ chelating activity assays. The results of the antioxidant tests showed that the extracts possess a different antioxidant ability: particularly, the extract of M. fruticulosa subsp. fruticulosa exhibited higher radical scavenging activity than that of subsp. coronopifolia (IC50 = 1.25 ± 0.02 mg/mL and 2.86 ± 0.05 mg/mL), which in turn displayed better chelating properties (IC50 = 1.49 ± 0.01 mg/mL and 0.63 ± 0.01 mg/mL). Lastly, Artemia salina lethality bioassay was performed for toxicity assessment. The results of the bioassay showed lack of toxicity against brine shrimp larvae for both extracts The data presented indicate the infraspecific taxa of M. fruticulosa as new and safe sources of antioxidant compounds

Nutritional, soluble carbohydrates and aroma volatile profiles of Tunisian wild Swiss chard leaves (Beta vulgaris L. var. cicla) have been characterized. The chem. composition of an ethanol chard leaves extract, as well as its in vitro antioxidant, α-amylase and α-glucosidase inhibition activities were carefully evaluated. The results of the proximate composition showed that total carbohydrate fraction, mainly as dietary fiber were the major macronutrient (2.43 g/100 g fw), being the insoluble dietary fiber the predominant fraction (2.30 g/100 g). In addition, leaves of Beta vulgaris L. were especially rich in Mg, Fe and Ca (4.54, 2.94 and 2.28 mg/100 g fw) and very poor in Na (0.09 mg/100 g fw). Volatile profile revealed that non-terpene derivatives and sesquiterpene hydrocarbons were the essential classes of volatiles in the chard leaves. Myricitrin, p-cumaric acid and rosmarinic acid were characterized. Moreover, the ethanol extract of wild Swiss chard leaves revealed significant antioxidant capacity. Furthermore, a good enzyme inhibitory effects on α-glucosidase and α-amylase activities were observed These findings highlighted the potential health benefits of wild Swiss Chard as a source of nutritional and bioactive compounds

Mora-Gutierrez, Adela published the artcileMixed Biopolymer Systems Based on Bovine and Caprine Caseins, Yeast β-Glucan, and Maltodextrin for Microencapsulating Lutein Dispersed in Emulsified Lipid Carriers, Computed Properties of 110-42-9, the main research area is caprine casein yeast glucan maltodextrin microencapsulating lutein lipid carrier; biopolymers; emulsified lipid carriers; lutein; microencapsulation; spray drying; storage stability.

Lutein is an important antioxidant that quenches free radicals. The stability of lutein and hence compatibility for food fortification is a big challenge to the food industry. Encapsulation can be designed to protect lutein from the adverse environment (air, heat, light, pH). In this study, we determined the impact of mixed biopolymer systems based on bovine and caprine caseins, yeast β-glucan, and maltodextrin as wall systems for microencapsulating lutein dispersed in emulsified lipid carriers by spray drying. The performance of these wall systems at oil/water interfaces is a key factor affecting the encapsulation of lutein. The highest encapsulation efficiency (97.7%) was achieved from the lutein microcapsules prepared with the mixed biopolymer system of caprine αs1-II casein, yeast β-glucan, and maltodextrin. Casein type and storage time affected the stability of lutein. The stability of lutein was the highest (64.57%) in lutein microcapsules prepared with the mixed biopolymer system of caprine αs1-II casein, yeast β-glucan, and maltodextrin, whereas lutein microcapsules prepared with the biopolymer system of bovine casein, yeast β-glucan, and maltodextrin had the lowest (56.01%). The stability of lutein in the lutein microcapsules dramatically decreased during storage time. The antioxidant activity of lutein in the lutein microcapsules was closely associated with the lutein concentration

Mohammadi, Ghobad published the artcileChemical characterization and anti-breast cancer effects of silver nanoparticles using Phoenix dactylifera seed ethanolic extract on 7,12-Dimethylbenz[a] anthracene-induced mammary gland carcinogenesis in Sprague Dawley male rats, Formula: C11H22O2, the main research area is breast cancer silver nanoparticle Phoenix seed extract antitumor.

The aim of the recent research was to investigate the anti-breast cancer effects of silver nanoparticles using Phoenix dactylifera seed ethanolic extract (AgNPs). After preparation of Phoenix dactylifera seed extract, GC/MS was performed to detect the compounds The findings indicated that 9-Octadecenoic acid (Z)- Me ester (40.95%) and Dodecanoic acid Me ester (20%) were the most frequent constituents found in P. dactylifera. These nanoparticles were spherical with a size range of 17-19 nm and characterized using various anal. techniques including UV-Vis absorption spectroscopy to determine the presence of AgNPs in the solution We studied functional groups of P. dactylifera extract in the reduction and capping process of AgNPs by FT-IR, crystallinity and FCC planes by X-ray diffraction (XRD) pattern and surface morphol., shapes, and size of AgNPs by SEM and transmission electron microscopy (TEM). DPPH free radical scavenging test was used to test the antioxidant properties of P. dactylifera and AgNPs, which revealed high antioxidant potential similar to butylated hydroxy toluene (BHT) as the pos. control. The results of cytotoxicity anal. indicated that P. dactylifera and AgNPs were toxic for MCF-7 cells. In vivo design, induction of breast cancer was done by 7,12-Dimethylbenz[a] anthracene (DMBA) in 50 animals. After 10 days, the animals were randomly divided into six subgroups, including healthy control, untreated control, two groups receiving the P. dactylifera at 2 and 6 mg/kg and two groups receiving the AgNPs at 2 and 6 mg/kg concentrations Both doses of P. dactylifera and AgNPs (especially AgNPs6) significantly (p â‰?0.05) reduced the weight and volume of liver, mammary gland, kidney, spleen, ALP, AST, ALT, GGT, cholesterol, LDL, triglyceride, total and conjugated bilirubin, urea, creatinine, glucose, ferrous, ferritin, erythropoietin, GR, IL1, IL6, IL12, IL18, IFNY, and TNFα and increased HDL, total protein, albumin, WBC, lymphocyte, neutrophils, platelet, RBC, Hb, PCV, MCV, MCH, MCHC, SOD, CAT, GPx, IL4, IL5, IL10, IL13, and IFNα compared to the untreated group. Moreover, P. dactylifera and AgNPs (especially AgNPs6) significantly (p â‰?0.05) treated breast cancer with reduction of organs free of metastasis compared to the untreated group. Seemingly, the AgNPs can be used for the treatment of breast cancer.

Fan, Xiaqiong published the artcileDeep-Learning-Assisted multivariate curve resolution, COA of Formula: C11H22O2, the main research area is deep learning assisted multivariate curve resolution; Deep Learning; GC-MS; Multivariate Curve Resolution.

Gas chromatog.-mass spectrometry (GC-MS) is one of the major platforms for analyzing volatile compounds in complex samples. However, automatic and accurate extraction of qual. and quant. information is still challenging when analyzing complex GC-MS data, especially for the components incompletely separated by chromatog. Deep-Learning-Assisted Multivariate Curve Resolution (DeepResoln.) was proposed in this study. It essentially consists of convolutional neural networks (CNN) models to determine the number of components of each overlapped peak and the elution region of each compound With the assistance of the predicted elution regions, the informative regions (such as selective region and zero-concentration region) of each compound can be located precisely. Then, full rank resolution (FRR), multivariate curve resolution-alternating least squares (MCR-ALS) or iterative target transformation factor anal. (ITTFA) can be chosen adaptively to resolve the overlapped components without manual intervention. The results showed that DeepResoln. has superior compound identification capability and better quant. performances when comparing with MS-DIAL, ADAP-GC and AMDIS. It was also found that baseline levels, interferents, component concentrations and peak tailing have little influences on resolution result. Besides, DeepResoln. can be extended easily when encountering unknown component(s), due to the independence of each CNN model. All procedures of DeepResoln. can be performed automatically, and adaptive selection of resolution methods ensures the balance between resolution power and consumed time. It is implemented in Python and available at https://github.com/XiaqiongFan/DeepResoln.

Ruiperez, Violeta published the artcileContinuous malolactic fermentation of red wine in a reactor using silica-alginate encapsulated Oenococcus oeni, Category: esters-buliding-blocks, the main research area is Oenococcus oeni encapsulation red wine malolactic fermentation reactor.

Malolactic fermentation (MLF) is a challenging and time-consuming step in the winemaking process. The effects of climate change are making the intrinsic conditions in red wine more challenging for the growth of lactic acid bacteria through interfering with a prompt and effective MLF. However, this is a necessary process in red wine production that contributes to high quality of wine demanded by consumers. Previous studies in our group reported a highly efficient MLF of red wine by using encapsulated Oenococcus oeni. Here, we designed a bench-scale packed-bed reactor using encapsulated bacteria to facilitate and speed up this process. The time to complete MLF was reduced as the concentration of biocapsules increased. The system exhibited operational stability and efficiency in sequential batches of wine recirculated through the column. Furthermore, an efficient continuous MLF was achieved using the packed-bed reactor. In general, a slight reduction in the concentration of some volatile organic compounds (VOCs) in the wines from the continuous system was observed as compared to those from the recirculated system.

Cardona, Luis F. published the artcileExtension of a group contribution method to predict viscosity based on momentum transport theory using a modified Peng-Robinson EoS, SDS of cas: 110-42-9, the main research area is group contribution method viscosity momentum transport theory PengRobinson EoS.

In this work, a semitheoretical model based on the momentum transport theory is generalized through the development of a group contribution method. Viscosity data for temperatures between 13.95 and 950 K and pressures from 1.00 x 10-3 bar up to 1.00 x 104 bar were used to develop and to validate the model. To perform viscosity calculations, the model requires d. and residual enthalpy that were obtained from a modified Peng-Robinson equation of state. Also, the model has one adjustable parameter that can be estimated form the group contribution method. Viscosity was calculated for 256 substances including 95 non-polar and 161 polar compounds In total, 23 organic families were considered. Average deviations below 6.67% were calculated The performance of the model was compared with those of other models reported in the literature. Calculations were carried out to include the saturation and single-phase regions. In general, it can be considered that the proposed model describes viscosity adequately using only one adjustable parameter.
