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...
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...
Abstract Purple glutinous rice bran (Kum Doi Saket (KUM)) contains high content of edible polysaccharides and anthocyanins has an excellent antioxidant activity. This research aimed to optimize the extraction crude from defatted purple using ultrasonic-assisted (UAE) compared with a hot water (HWE). Results showed that optimal condition was as follows: ratio 1:20 w/v, temperature time 70 °C for 20 min. Under condition, yield polysaccharide UAE (4%) significantly higher than obtained HWE...
Consumption of pigmented rice as a staple food is rapidly increasing due to their healthy prospective and considered functional ingredients. Greater interest has been shown in many color varieties multiple biological activities. The phenolic compounds have found consist anthocyanidins, ferulic acid, diferulates, anthocyanins polymeric proanthocyanidins. Anthocyanin located the bran layers kernel, while acids are mainly present rice, existing free, conjugated bound forms. Keeping view several...
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...
Basils of the genus Ocimum are aromatic plants grown widely throughout tropical and temperate regions. The essential oils obtained from their aerial parts enriched with volatile organic compounds high market demand for food pharmaceutical industries. have been shown to exhibit biological activities. Therefore, novel applications extensively explored in last few decades. most available basils areas include white holy basil (O. sanctum var. Shyama), red Rama), Thai basilicum thyrsiflorum),...
Delignification can be considered as a feasible process to pretreat lignocellulosic biomass in xylooligosaccharides production after the performance and efficiency has been improved through few modifications. This study compared various pretreatment strategies such Fenton, sonocatalytic, sonocatalytic–synergistic Fenton employed on corncob order expose lignin content saccharides enhance yield by enzymatic hydrolysis. The dissolution of was enhanced ultrasound assisted TiO2 reaction....
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...
Summary An egg coating was developed to preserve the internal quality of eggs by mixing cassava starch (CS), gelling agents and fatty acids. Hydroxypropyl methylcellulose (HPMC) carboxymethyl cellulose (CMC) were used as agents. Palm oil acid (PO) incorporated. Coated non‐coated evaluated over a period 4 weeks at 28 °C yolk colour, weight loss, albumen pH Haugh unit testing. The deteriorated from AA B grade after 3 weeks, with values below detection limit weeks. optimum 6/1/3 w/v%...
This study aimed to select thermotolerant yeast for bioethanol production from cellulose-rich corncob (CRC) residue. An effective strain was identified as Saccharomyces cerevisiae TC-5. Bioethanol CRC residue via separate hydrolysis and fermentation (SHF), simultaneous saccharification (SSF), prehydrolysis-SSF (pre-SSF) using this were examined at 35–42 °C compared with the use of commercial S. cerevisiae. Temperatures up 40 did not affect ethanol by The concentration obtained decreased...
Coffee cherry pulp (CCP) is a by-product of coffee bean production. CCP contains amounts phenolic compounds that are beneficial for animals. This study evaluated the impact extract (CCPE) supplementation on growth performance, meat quality, carcass characteristics, serum biochemistry, cecum microbial population, intestinal morphology, and immune antioxidant responses broilers. Five hundred 1-day-old Ross 308 chicks were randomly assigned to five groups: basal diet control, with antibiotic...
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...
Cellulase-free xylanase production by thermophilic Streptomyces thermovulgaris TISTR1948 was cultivated in a basal medium with rice straw as sole source of carbon and an inducible substrate. Variable components were selected accordance the Plackett-Burman experimental design. The optimization conditions physical factors (pH temperature levels) then combined further studies through response surface methodology approach. Only two significant components, yeast extract, chosen for studies. A...
