Curcumin is a phenolic compound derived from turmeric roots (Curcuma longa L.). This research studied the effects of curcumin extract on properties chitosan films. The film characteristics measured included mechanical properties, visual aspects, color parameters, light transmission, moisture content, water solubility, vapor permeability, infrared spectroscopy, and antioxidant activity. results suggest that adding to chitosan-based films increases yellowness barriers. Infrared spectroscopy...
This study was aimed at creating new films and determine some functional packaging properties of pectin:nanochitosan with ratios (P:NSC) 100:0; 75:25; 50:50; 25:75 0:100 (%w/w). The effects the proportions incorporation on thickness, mechanical properties, water vapor permeability, water-solubility, oxygen permeability were investigated. microstructural studies done using scanning electron microscopy (SEM). interactions between pectin nanochitosan elucidated by Attenuated total...
This study aimed at developing the functional packaging properties of pectin/alginate films by adding zinc oxide nanoparticles (ZnO-NPs). The ZnO-NPs were added to film concentrations 0.5, 2.5, 5, and 25 g/100 g blended polymer. effects ZnO-NP incorporation on mechanical properties, hydration oxygen permeability, ultraviolet transmission, transparency, antimicrobial activity investigated. addition from 0 5 polymer increased 191.4% tensile strength, 169.8% elongation break, (against...
Cellulose from Asparagus officinalis stalk end was extracted and synthesized to carboxymethyl cellulose (CMCas) using monochloroacetic acid (MCA) via carboxymethylation reaction with various sodium hydroxide (NaOH) concentrations starting 20% 60%. The CMCas were characterized by the physical properties, Fourier Transform Infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC), Scanning electron microscopy (SEM) X-ray diffraction (XRD). In addition, mechanical properties of...
Bacterial cellulose from nata de coco was prepared the fermentation of coconut juice with Acetobacter xylinum for 10 days at room temperature under sterile conditions. Carboxymethyl (CMC) transformed bacterial by carboxymethylation using different concentrations sodium hydroxide (NaOH) and monochloroacetic acid (MCA) in an isopropyl (IPA) medium. The effects various NaOH on degree substitution (DS), chemical structure, viscosity, color, crystallinity, morphology thermal properties...
The aim of this work was to synthesize carboxymethyl cellulose (CMC) and produce CMC films from the palm bunch bagasse agricultural waste. effect various amounts H2O2 (0-40% v/v) during delignification on properties cellulose, CMC, studied. As content increased, yield lignin decreased, whereas lightness (L*) whiteness index (WI) increased. FTIR confirmed substitution a group structure. A higher degree both sources found when 20%-30% employed. trend in L* WI values each film related those...
This study investigated the effect of chitosan particle sizes on properties carboxymethyl (CMCh) powders and films. Chitosan with different (75, 125, 250, 450 850 µm) were used to synthesize CMCh powders. The yield, degree substitution (DS), water solubility then determined. films prepared based fabricated by a solution casting technique. solubility, mechanical properties, vapor transmission rate (WVTR) measured. As size decreased, DS, synthesized increased. increase in was due an polarity...
Nata de coco has been used as a raw material for food preparation. In this study, the production of carboxymethyl cellulose (CMC) film from nata and effect monochloroacetic acid on bacterial (CMCn) its were investigated. Bacterial was modified into CMC form via carboxymethylation using various concentrations (MCA) at 6, 12, 18, 24 g per 15 cellulose. The results showed that different MCA affected degree substitution (DS), chemical structure, viscosity, color, crystallinity, morphology CMCn....
The aim of extending shelf-life and maintaining quality is one the major issues regarding mango fruit preservation. fruits greatly affected by postharvest factors, especially temperature treatment. In this study, effect coating storage on characteristics was investigated. were immersed in different concentrations (1.5%, 2.0%, 2.5%) pectin/nanochitosan dispersion (with ratios pectin:nanochitosan 50:50), (0.75%, 1% 1.25%) nanochitosan stored at 17, 25, 32 °C for 24 days. Changes fruit,...
Carboxymethyl rice starch films were prepared from carboxymethyl (CMSr) treated with sodium hydroxide (NaOH) at 10-50% w/v. The objective of this research was to determine the effect NaOH concentrations on morphology, mechanical properties, and water barrier properties CMSr films. degree substitution (DS) morphology native powders examined. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), differential scanning calorimetry (DSC) used investigate chemical structure,...
A nanochannel-based electrochemical sensor for the detection of trace amounts erythromycin has been developed. The is capable specifically detecting erythromycin, at a sensitivity 0.001 parts per trillion, in various water samples and potential utility assessment environmental quality.
There is an urgent need for the development of alternative strategies effective drug delivery to improve outcome patients suffering from deadly diseases such as cancer. Nanoparticles, in particular layered double hydroxide (LDH) nanoparticles, have great potential nanocarriers chemotherapeutic molecules.
