[PDF] ANTIOXIDANT ABILITIES COMPARISON OF LIGNINS WITH THEIR

Black liquor alkaline lignin and magnesium lignosulfonate were liquefied at 320 oC. The antioxidant abilities of the liquefaction products were compared with the raw materials. Results showed that the total phenol content and unit antioxidant power of both alkaline lignin liquefaction products (ALLP) and magnesium lignosulfonate liquefaction products (MLLP) were improved, and ALLP had a larger ...

Antioxidant abilities comparison of lignins with their hydrothermal

Recent studies have revealed the efficiency, as antioxidants in different composite materials, of lignins isolated from wood by different methods of deligni?cation, including alkaline pulping and some lignin-related monomeric and dimeric compounds (Dobeleet al. 2009).

A review on lignin antioxidants: Their sources, isolations, antioxidant

Lignin samples exhibit comparable radicals scavenging ability to commercial ones, showing their potential as renewable alternatives of synthesized antioxidants. Besides, their applications have also been discussed, which demonstrates lignin potential as an inexpensive antioxidant additive and consequent improvements on multiple functionalities.

Enhancement of the antioxidant abilities of lignin and lignin

The antioxidant activities of the above samples were evaluated in terms of their capacity to scavenge ABTS and DPPH free radicals, and the results are shown in Fig. 8. In general, all samples exhibited excellent antioxidant capability, as their ABTS and DPPH scavenging effect intensified with increasing the concentration [7], [66]. Both LD-RL ...

Antioxidant Activity of the Lignins Derived from Fluidized-Bed Fast

Lignins have antioxidant potential, which is their capacity to quench the production of free radicals, and their ability to stabilize free radicals induced by oxygen and its radical species. A better understanding of natural antioxidants from pyrolytic lignins will facilitate their use in the food industry and as feedstock as value-added chemicals to preserve food, colour, flavor, and active ...

Antioxidant, antimicrobial, and antimutagenic properties of technical

One of the most studied properties of lignins is their antioxidant activity, ( e.g., their ability to act as radical scavengers), with the aim of using them as natural additives to replace synthetic or semi-synthetic compounds in cosmetics, pharmaceuticals, and polymeric formulations (Ugartondo et al. 2008; Vinardell et al. 2008; Lu et al. 2012b).

Enhancement of the antioxidant abilities of lignin and lignin

The studied lignins have interesting and promising biomedical properties. The main feature of lignins is their high antioxidant activity (AOA), which is comparable with the activity of well-known low molecular weight antioxidants. It was shown that lignins from acacia and walnut wood were characterized by the highest AOA. In addition, lignins ...

Study on the Antioxidant Activity of Lignin and Its Application

The lignin extracted with ethyl acetate got the lowest molecular weight and highest phenolic hydroxyl group content, showing even better free radical scavenging ability than the commercial Irganox1010. Lignin/SBS elastomer composites were prepared with even dispersion of lignin in the SBS matrix with an average particle size close to 40 nm.

Lignin as a UV blocking, antioxidant, and antimicrobial ...

The scavenging ability of lignins, which is like the general mechanism of monomeric phenols, is what gives them their antioxidant characteristics . Increasing heterogeneity, dispersity, molecular weight average, and carbohydrate admixtures have a negative impact on lignin's ability to scavenge radicals.
