Anthocyanins-based colorimetric volatile amines sensors have recently received great attention for monitoring meat and fish freshness. However, most of the sensors suffered from anthocyanins leaching problems in humid packaging environments, severely limiting their indication ability. The present study developed a hydrogel-in-oleogel bigel to protect anthocyanins from leaching. The internal hydrogel was composed of water, agar and purple sweet potato anthocyanins (PSPA), and the external oleogel was made up of sunflower oil, beeswax and glyceride monooleate (GMO). The agar concentration and water-to-oil-phase volume ratio (W/O) were optimized to be 1.0% and 2:8, resp. The optimal pH value of hydrogel was determined to be 6.50, taking into consideration of the gas sensitivity and color stability of the bigel. The bigel was extruded onto polyvinylidene fluoride (PVDF) film through a 3D printing method to form the composite film. The results of the study revealed that PVDF-bigel composite film showed good stability in water, indicative of strong anti-leaching properties. Meanwhile, the PVDF-bigel film was sensitive to trimethylamine (TMA) with a limit of detection of 2.52μM. The PVDF-bigel film was subjected to in-situ and real-time monitor beef and salmon freshness. The film exhibited a red-to-purple color change upon reacting with volatile amines generated from beef and salmon. Henceforth, this study presented a new method to develop anthocyanins-based colorimetric gas sensors for intelligent food packaging. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1COA of Formula: C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.COA of Formula: C21H44O5

Processing and Characterization of Food-Grade Plasticizer-Compatibilized Cellulose Nanocrystals and Ethylene Vinyl Alcohol Copolymer Nanocomposites was written by Nuruddin, Md;Hamlin, Justin;Clarkson, Caitlyn M.;Howarter, John A.;Szczepanski, Caroline R.;Youngblood, Jeffrey P.. And the article was included in ACS Applied Polymer Materials in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

In the food-packaging industry, ethylene vinyl alc. (EVOH) is an attractive material due to its excellent gas barrier properties. Unfortunately, moisture sensitivity drastically limits the use of EVOH for packaging applications. To address this shortcoming, EVOH is often layered with other thermoplastic polymers or blended with nanomaterials to create films suitable for food packaging. However, these current nanocomposite strategies are still quite limited as a large volume of solvent is typically required. In this work, we present an approach to develop a food grade, EVOH nanocomposite material containing cellulose nanocrystals (CNCs) via melt compounding. Two food-grade plasticizers (monolaurin and glyceryl monostearate) were studied as potential compatibilizers, and the compatibility of both plasticizers with CNCs and EVOH were evaluated using Hansen solubility parameters (HSPs). The Hansen solubility spheres indicated that monolaurin is a good compatibilizer, and it was thus studied exptl. Excellent dispersion of CNCs into EVOH was achieved by compounding premixed monolaurin and CNCs, prepared by codissoln./evaporation in a suitable ethanol/water cosolvent. Nanocomposite films with effective CNC dispersion prepared in this study also showed enhanced mech., thermal, and water barrier properties. Our results demonstrate the applicability of CNC/monolaurin/EVOH films for packaging applications and demonstrate, for the first time, effective dispersion of CNCs into a food-grade EVOH barrier material using melt compounding. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Category: esters-buliding-blocks).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters.

Dose-Dependent Effect of Wedelia trilobata Essential Oil (EO) on Lettuce (Lactuca sativa L.) with Multivariate Analysis was written by Azlan Azizan, Kamalrul;Izzairy Zamani, Arief;Azlan Nor Muhammad, Nor;Khairudin, Khairunisa;Yusoff, Nornasuha;Firdaus Nawawi, Mohamad. And the article was included in Chemistry & Biodiversity in 2022.Name: Glyceryl monostearate The following contents are mentioned in the article:

Understanding metabolite changes and underlying metabolic pathways that may be affected in target plants following essential oils (EOs) exposure is of great importance. In this study, a gas chromatog.-mass spectrometry (GC/MS) based metabolomics approach was used to determine the metabolite changes in lettuce (Lactuca sativa L.) shoot and root after exposure to different concentrations of W. trilobata EO. Multivariate analyses of principal component anal. (PCA) and orthogonal partial least-discriminant anal. (OPLS-DA) corroborated that shoot and root of lettuce responded differently to W. trilobata EO. In EO-exposed shoot samples, an increase in the levels of malic acid, glutamine, serine, lactose and α-glucopyranose affected important metabolism pathways such as glycolysis, fructose and mannose metabolism and galactose metabolism The findings suggest that lettuce may be up-regulating these metabolites to increase tolerance against W. trilobata EO. In EO-exposed root samples, changes in fatty acid biosynthesis, elongation, degradation, phenylalanine, tyrosine and tryptophan metabolism were linked to a decrease in lyxose, palmitic acid, octadecanoic acid, aspartic acid, phenylalanine and myo-inositol. These results indicate that W. trilobata EO could cause alterations in fatty acid compositions and lead to inhibition of roots growth. Together, these findings provide insight into the metabolic responses of lettuce upon W. trilobata EO exposure, as well as potential mechanisms of action of W. trilobata EO as bio-herbicides. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Name: Glyceryl monostearate).

Precipitate in B20 fuel stored in storage tanks can accumulate at the bottom level of the tank and affect the fuel filter, clogging in the fuel distribution and engine system. This study examines the precipitate formation prediction in B20 fuel based on the monoglyceride content in biodiesel. This research used a modified CSFT method of ASTM D7501 for the precipitation test. Monopalmitin was added to biodiesel with a variation of monoglyceride content. Each biodiesel sample was then blended with petroleum diesel fuel to produce two groups of samples. Each sample was sep. soaked in the cooling chamber at constant and room temperature for 21 days. The bottom layer of each B20 fuel sample stored in the measuring cylinder was then pipetted and filtered, washed with petro-ether, vacuum-dried, and weighed for a constant amount of precipitate retained on the filter. The simulation results show that the ratios between the amount of collected precipitate at the bottom layer of the 2-L measuring cylinder and the total amount of collected precipitate for the 2-L measuring cylinder increased with the monoglyceride content biodiesel. This ratio was used to predict the amount of accumulated sludge for a given volume of B20 fuel loaded into the storage tank. This study shows the effect of monoglyceride content on the precipitation behavior in the storage tank concerning general tank storage dimension parameters and B20 loading frequency. This approach can be applied to estimate the sludge removal frequency for biodiesel storage. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Product Details of 31566-31-1).

Carboxymethyl chitosan (CMCH) from native chitosan of high mol. weight (H, 310-375 kDa) was synthesized for improving water solubility The water solubility of high-mol.-weight carboxymethyl chitosan (H-CMCH) was higher than that of native chitosan by 89%. The application of H-CMCH as enhancing the moisturizer in mangosteen extract deodorant cream was evaluated. Different concentrations of H-CMCH (0.5-2.5%) were investigated in physicochem. characteristics of creams, including appearance, phase separation, pH, and viscosity, by an accelerated stability test. The different degrees of skin moisturizing (DM) on pig skin after applying H-CMCH solution, compared with untreated skin, water, and propylene glycol for 15 and 30 min using a Corneometer, were investigated. The results showed that the 0.5% H-CMCH provided the best DM after applying the solution on pig skin for 30 min. Trans-2-nonenal, as an unsatisfied odor component, was also evaluated against components of the mangosteen extract deodorant cream, which were compared to the standard, epigallocatechin gallate (EGCG). In addition, DPPH and ABTS radical scavenging activity, ferric reducing antioxidant power (FRAP), and antibacterial activities were examined for the mangosteen extract deodorant cream using 0.5% H-CMCH. Results indicated that the mangosteen extract synergized with H-CMCH, which had a good potential as an effective skin moisturizing agent enhancer, deodorizing activity on trans-2-nonenal odor, antioxidant properties, and antibacterial properties. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Reference of 31566-31-1

Sorafenib (SRB), a multikinase inhibitor, is effective in reducing exptl. corneal neovascularization (CNV) after oral administration; however, its therapeutic use in ocular surface disorders is restricted due to poor solubility and limited bioavailability. This study aimed to develop and optimize SRB-loaded nanostructured lipid carriers (SRB-NLCs) for topical ocular delivery by a central composite design response surface methodol. (CCD-RSM). It was spherical and uniform in morphol. with an average particle size of 111.87 ± 0.93 nm and a narrow size distribution. The in vitro drug release from the released SRB-NLC formulation was well fitted to Korsmeyer Peppas release kinetics. The cell counting kit-8 (CCK-8) cell viability assay demonstrated that SRB-NLC was not obviously cytotoxic to human corneal epithelial cells (HCECs). An in vivo ocular irritation test showed that SRB-NLC was well tolerated by rabbit eyes. Ocular pharmacokinetics revealed 6.79-fold and 1.24-fold increase in the area under concentration-time curves (AUC_0-12h) over 12 h in rabbit cornea and conjunctiva, resp., treated with one dose of SRB-NLC compared with those treated with SRB suspension. Moreover, SRB-NLC (0.05% SRB) and dexamethasone (0.025%) similarly suppressed corneal neovascularization in mice. In conclusion, the optimized SRB-NLC formulation demonstrated excellent physicochem. properties and good tolerance, sustained release, and enhanced ocular bioavailability. It is safe and potentially effective for the treatment of corneal neovascularization.

Catastrophic phase inversion of bigels characterized by fluorescence intensity-based 3D modeling and the formability for decorating and 3D printing was written by Jiang, Qinbo;Wang, Yuxin;Du, Liyang;Li, Shaoyang;Liu, Yuanfa;Meng, Zong. And the article was included in Food Hydrocolloids in 2022.COA of Formula: C21H44O5 The following contents are mentioned in the article:

In this paper, gelatin hydrogels and glycerol monostearate (GMS)-enhanced Et cellulose (EC) oleogels were used as two phases for preparing bigels. The proportion of components in bigels was changed to explore the catastrophic phase inversion of bigels, which was analyzed by textural, rheol., laser confocal imaging, 3D stack modeling of techniques, and the measurement of the hydrophile-lipophile balance (HLB). As the oleogel fraction was less than 40 wt%, the bigel presented as the O/W type, and oil droplets were evenly distributed and stabilized by the gelatin, having the size smaller than 15μm. When the oleogel fraction was 42 wt%, bigels exhibited the semibicontinuous state due to the critical HLB of 8.23 that water and oil phases both had continuous and dispersed phases concurrently. The 3D model of bigels calculated a sharp increase of droplet sizes to 35μm in the transition state. The water phase in bigels became the dispersed phase when the oleogel fraction was more than 44 wt%, and GMS was mainly responsible for emulsifying and stabilizing water droplets, and the size of water droplets decreased from 35μm. Applications of bigels in decorating and 3D printing were discussed combined with phys. properties of different types of bigels. O/W bigels containing 40 wt% oleogels could inherit the hardness and formability from gelatin hydrogels and have ideal rheol. properties for decorating. W/O bigels with 60 wt% oleogels were more suitable to be used as printing ink for 3D printing, resulting from the strong thixotropy of EC oleogels.

Acne is a skin condition arising from excess sebum production and microbial overgrowth within the pilosebaceous unit. Several com. essential oils have shown promising activity against acne-related pathogens. Due to their volatility and thermal instability, the formulation of essential oils into com. products remains a pharmaceutical challenge. Thus, this study aimed to develop a viable anti-acne topical treatment as an oil-in-water emulsified lotion to overcome these challenges. Chrysopogon zizanioides(vetiver) displayed noteworthy antimicrobial activity with a mean min. inhibitory concentration of 0.14 mg/mL against Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. Emulsified lotions containing C. zizanioideswere developed through the hydrophilic-lipophilic balance approach. At tested hydrophilic-lipophilic balance values of 8, 9, and 10, C. zizanioidesemulsified lotions displayed maximum stability at hydrophilic-lipophilic balance 9 with a min. change in mean droplet size and polydispersity index of 20.61 and 33.33%, resp., over 84 days. The C. zizanioidesemulsified lotion at optimum hydrophilic-lipophilic balance 9 completely inhibited the growth of C. acnesand killed S. aureus, S. epidermidis, and S. pyogeneswithin 24 h. Addnl., the lotion retained antimicrobial activity against these test micro-organisms over the 84-day stability test period. Thus, the C. zizanioidesemulsified lotion demonstrated phys. stability and antimicrobial efficiency, making it an ideal natural product anti-acne treatment.
