At present, more than 70 million tons per year of technical lignins are obtained from cellulose pulping and lignocellulosic refineries (e.g., kraft, lignosulfonates, soda, organosolv lignin). These commonly incinerated to produce steam energy, only a small part is used as an additive in various low volume niche applications, such dispersant, concrete admixtures, adhesive binder. Furthermore, the potential considered be beyond that inexpensive fuel or raw material added value products. The...

This work presents an overview method, advantages, potential applications industries for improving quality products.

A novel pectin was acid extracted from chickpea husk (CHP). CHP presented a 67% (w/w) of galacturonic acid, an intrinsic viscosity 374 mL/g and viscosimetric molecular weight 110 kDa. Fourier transform infrared spectroscopy spectrum indicated degree esterification about 10%. The CHP-calcium system formed ionic gels with storage (G’) modulus 40 Pa gel set time (G’ > G’’) 3 min at 1% (w/v), G’ 131 1 2% (w/v). not greatly affected by temperature. results attained suggest that can be...

Lignin contributes to the recalcitrance of lignocellulosic biomass and affects enzymatic activity during biorefinery operations. Therefore, it must be removed before further processing. Organic solvents (organosolv) ionic liquids are two important pretreatments for delignifying biomass. They have proven beneficial fractionating recovering cellulose hemicellulose, as well lignin with useful physicochemical properties. Volatility harsh conditions acidic systems that result in toxicity,...

Homogeneous and thin porous membranes composed of oriented fibers were obtained from wheat gluten (WG) using the electrospinning technique. SEM micrographs showed an asymmetric structure some porosity, which, in addition to a small thickness 40 mm, are desirable characteristics for membranes’ potential application release systems. The loaded with urea obtain pastilles. FT-IR DSC studies confirmed existence interactions via hydrogen bonding between WG proteins. pastilles studied as...

Abstract A simple and specific analytical method was developed tested for the determination of sulforaphane in broccoli by‐products. The includes optimization conversion glucoraphanin to sulforaphane, followed by purification extracts using solid‐phase extraction high‐performance liquid chromatography (HPLC) analysis. response surface methodology used find optimum conditions preparation procedure. Chromatographic reversed‐phase HPLC with UV photodiode array detection were as follows: column,...

Cellulose nanofibers from durum wheat straw (Triticum durum) were produced and characterized to study their potential as reinforcement fibers in biocomposites. was isolated by chemical treatment. Nanofibers via an electrospinning method using trifluoroacetic acid (TFA) the solvent. The 270 ± 97 nm diameter. Analysis of FT-IR spectra demonstrated that treatment removed hemicellulose lignin. XRD revealed crystallinity cellulose reduced after electrospinning, but remained highly crystalline....

Conventional plastic materials accumulation has led to a constant search develop friendly packaging, edible coatings from biopolymers are an example. Since different proteins have behavior and plastizicer compatibility, in this work, the effect of polyalcohols (glycerol, sorbitol, maltitol, mannitol, xylitol) as plasticizers on squid protein films was studied. The results show that except for transparent, flexible can be obtained. None them showed transmission light ultraviolet (UV)...

Naturally aflatoxin-contaminated corn (Zea mays L.) was made into tortillas, tortilla chips, and chips by the traditional commercial alkaline cooking processes. The nixtamalization (alkaline-cooking) process involved steeping corn, whereas only steeps in a hot solution (initially boiling). A pilot plant that includes cooker, stone grinder, celorio cutter, oven used for experiments. eliminated 51.7, 84.5, 78.8% of aflatoxins content tortilla, respectively. less effective: it removed 29.5,...

Summary The antibacterial effect of polyamide 6/66‐chitosan blend and chitosan‐coated plastic films was compared to chitosan solution, against Salmonella typhimurium Staphylococcus aureus . did not show inhibition halos; however, contact observed. During the tests, absorbed moisture, increasing diameter discs in relation concentration for both microorganisms at least 31%. Chitosan film coating (bilayer system) showed only inhibition, without increase area. from had no activity. highest...

Lignin conveys several important and useful characteristics to starch films depending on the lignin MW, extraction procedure, botanical source. In this study, was obtained from durum wheat straw through organosolv process, followed by fractionation according solubility in alcohol. The alcohol‐soluble (ASL) then used prepare starch–ASL films. mechanical properties, thermal stability, water solubility, color, antioxidant activity of resulting were evaluated, also analyzed means SEM attenuated...

The aim of this study was to evaluate the effects freezing rate and storage time on properties frozen wheat dough starch. at either slow (−0.14°C/min) or fast (−1.75°C/min) rates stored −20°C for 8 weeks. Every 2 weeks, sampled freeze‐dried. Analyses dried included damaged starch, paste properties, thermal, morphological, structural properties. Damaged starch increased significantly during storage, it higher in a than rate. peak viscosity gradually but decreased. During period, enthalpy...

Summary Maize with a modified amino acid profile, i.e. greater amounts of lysine and tryptophan than normal, is known as ‘quality protein maize’ (QPM). The objective this work was to find the best combination extrusion process variables produce QPM flour for making tortillas. grits were mixed lime water had moisture content 28%. single screw extruder operation conditions selected from factorial three variables: temperature (ET, 70–100 °C), concentration (LC, 0.1–0.3% maize weight) velocity...
