Meat is an important protein source in the human diet; however, consumption of animal proteins needs to be reduced. Plant-based foods naturally lack cobalamin, vitamin B12 (VitB12), essential diet. Brewer's spent grain (BSG) a side stream available large volumes that was chosen as substrate for food-grade VitB12-producing microorganisms. microorganisms were identified scientific literature and selected study situ production VitB12 protein-enriched (53%) BSG. A first screening performed using Propionibacterium freudenreichii Priestia megaterium (formerly known Bacillus megaterium) strains. Further optimisations exploited increase BSG content further resulted levels up 21 μg VitB12/100 g at lab scale. Finally, experiments 12 kg scale fermentation with stabilized pH 7.7 BSG, indicating potential fortification by P. freudenreichii. Overall, it found VitB12-fortified could serve relatively inexpensive plant-based food feed applications. This shows offers opportunities fortify (protein-enriched) or other derivatives VitB12.

Vanillin, one of the most widely used and appreciated flavoring agents worldwide, is main constituent vanilla bean extract, obtained from seed pods various members belonging to Orchidaceae family. Due great demand in food confectionery industry, as well perfume medicine, more, majority vanillin today produced synthetically, only less than percent world’s market comes directly traditional natural sources. The increasing global for requires alternative overall sustainable new production methods, recovery biobased polymers, like lignin, an environmentally friendly chemical synthesis. present review provides firstly overview different types vanillin, followed by a description differences between synthetic their preparation, interest, authentication issues related analytical techniques. Then, explores real potentialities lignin production, presenting well-assessed classical methods moving towards recent promising approaches through chemical, biotechnological photocatalytic methodologies, together with challenges principal associated each technique.

ABSTRACT Potassium batteries are very appealing for stationary applications and domestic use, offering a promising alternative to lithium‐ion systems. To improve their safety environmental impact, gel polymer electrolytes (GPEs) based on bioderived materials can be employed. In this work, series of biobased membranes developed by crosslinking pre‐oxidized Kraft lignin as bio‐based component poly(ethylene glycol) diglycidyl ether (PEGDGE) functional linker with 200, 500, 1000 g mol −1 molecular weight. The influence PEGDGE chain length the physicochemical properties electrochemical performance GPEs potassium is investigated. These exhibit thermal stability above 240°C tunable glass transition temperatures depending Their mechanical determined rheology measurements in dry swollen states, evidencing slight decrease elastic modulus (G′) increasing length. An approximately one‐order‐of‐magnitude lower G′ value observed versus counterpart. Upon successful activation lignin‐based swelling liquid electrolyte embedding salts, these tested metal cell prototypes. systems ionic conductivity ~10 −3 S cm at ambient temperature. Interestingly, battery devices equipped GPE withstand current densities high 1.5 mA −2 during operation. Moreover, same reach specific capacities 130 mAh ‒1 0.05 A first 100 cycles long‐term operation over 2500 cycles, representing outstanding achievements bio‐sourced batteries.

In this work, a series of biobased phenolic resins were developed starting from kraft and soda lignin, suitably functionalized through esterification by means succinic anhydride. As result an extensive optimization study the functionalization curing reactions, clear correlations between lignin type chemical–physical characteristics properties resulting resin systems described. particular, reaction anhydride was found to play key role in enhancing chemical reactivity facilitating successful incorporation into formulations. The obtained high-lignin-content thermoset materials shown exhibit tunable (functionality, gel content, cross-linking density), thermal (glass transition temperature thermo-oxidative stability), mechanical (surface hardness, indentation modulus, creep behavior) characteristics, which could outperform those fully oil-based reference judicious control concentration characteristics. succinylated enable more efficient cured systems. This work provides first demonstration succinic-anhydride-modified-lignin formulation high-performance resins, ultimately contributing definition structure–property–performance for rational material design context advanced sustainable manufacturing.

Four different industrial BSG samples were present study, percentages malted cereals barley, wheat, degermed corn. Calcium's bioaccessibility higher BSG4 sample composed 50% barley wheat (16.03%), while iron presented highest value BSG2 (30.03%) 65% Pale Ale malt 35% Vienna malt. On other hand, B1 had (72.45%) BSG3 sample, whilst B6 registered lowest (16.47%) sample. Therefore, measuring bioaccessibilty bioactive compounds before their further use crucial assessing bioavailability.

Brewer's spent grain (BSG) is an important secondary raw material that provides a readily available natural source of nutraceuticals. It finds its largest application as animal feed and part the human diet, while future perspective predicts in production value-added products. In order to investigate sustainable BSG treatment method, two samples (BSG1 BSG2) were evaluated substrates for hydrolytic (xylanase, β-glucosidase cellulase) lignolytic enzymes (laccase, manganese peroxidase lignin peroxidase) by solid-state fermentation (SSF) with Trametes versicolor improving nutritional value. The biological was successful all laccase peroxidase, it unsuccessful peroxidase. Because BSGs chemically different, synthesized at different times had activities. Consequently, chemical composition end also different. positive effect on increase protein content, ash polyphenolic compounds, sugars BSG1. BSG2, there decrease content reducing sugars. Cellulose, hemicellulose, degraded BSG1, whereas only cellulose hemicellulose increased. fat decreased both samples. safety-related correctness analysis showed biologically treated sample did not contain any harmful components therefore safe use nutritionally enriched feed.
