Published: Feb. 22, 2023

Due to the worldwide consumption of coffee, many tons spent coffee grounds (SCGs) are discarded each year, as a by-product preparation. Not only their disposal is costly, but also it may cause release compounds that can endanger environment. However, there valuable chemical be extracted from SCGs and used in food industry. The aim this study was investigate main parameters affecting extraction caffeine polyphenols (i.e., chlorogenic acid, neochlorogenic caffeic acid) evaluate antioxidant properties extracts. To end, solvent, temperature, time, liquid-to-solid ratio were studied. A response surface methodology optimize process. According results, content optimum extract found 6.14 mg/g dry SCGs, total polyphenol 19.85 mg gallic acid equivalents/g, while ferric reducing power DPPH scavenging values 136.69 μmoL ascorbic equivalents/g 230.41 DPPH/g, respectively. experimental close agreement with predicted ones, highlighting potential for isolation bioactive proposed procedure.

Thermal Contaminants in Coffee Induced by Roasting: A Review

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(8), P. 5586 - 5586

Published: April 20, 2023

Roasting is responsible for imparting the main characteristics to coffee, but high temperatures used in process can lead formation of several potentially toxic substances. Among them, polycyclic aromatic hydrocarbons, acrylamide, furan and its derivative compounds, α-dicarbonyls advanced glycation end products, 4-methylimidazole, chloropropanols stand out. The objective this review present a current comprehensive overview chemical contaminants formed during coffee roasting, including discussion mitigation strategies reported literature decrease concentration these toxicants. Although occurs roasting step, knowledge production chain as whole important understand variables that will impact their concentrations different products. precursors routes are generally each contaminant, be quite some In addition, study highlights related decreasing precursors, modifying conditions eliminating/degrading contaminant. Many show promising results, there still challenges overcome, since little information available about advantages disadvantages relation aspects such costs, potential application on an industrial scale impacts sensory properties.

PLA Feedstock Filled with Spent Coffee Grounds for New Product Applications with Large-Format Material Extrusion Additive Manufacturing

ACS Omega, Journal Year: 2024, Volume and Issue: 9(6), P. 6423 - 6431

Published: Feb. 1, 2024

Food waste and loss generate significant such as spent coffee grounds (SCGs) from consumption. These byproducts can be valorized by following circular economy bioeconomy principles, e.g., using SCGs in polymer-based composites for 3D printing. Although desktop-size material extrusion additive manufacturing is increasingly adopted biomass-polymer-based composites, the potential of large-format direct printing systems remains unexplored. This work investigated thermal, rheological, mechanical properties PLA/SCG applications with a pellet printer. The formulations exhibit minimal degradation at typical temperatures PLA, i.e., ∼190 °C, limited effects on crystallinity increasing SCG weight percentage. decrease viscosity due to improves printability layer adhesion, confirmed tensile test results, higher ultimate strength elongation break values compared those state-of-the-art values. Using feedstocks contributes limiting thermomechanical reducing raw processing, avoiding filament extrusion. PLA/SCGs was demonstrated through printed complex parts nonplanar slicing techniques, including large-scale furniture product, validating printers scaling up use biomass-filled polymers.

A Review on the Applications of Coffee Waste Derived from Primary Processing: Strategies for Revalorization

Processes, Journal Year: 2022, Volume and Issue: 10(11), P. 2436 - 2436

Published: Nov. 17, 2022

Coffee is an extremely popular beverage worldwide. To obtain it, the berry must be depulped, fermented, washed, dried, and roasted, producing residues: pulp husk, mucilage, parchment. Recently there has been interest in generating high-value products. In this article, advances valorization process are critically reviewed, including overview of composition residues derived from primary processing, uses food, biocomposite, biofuel production (thermochemical conversion). With increasing coffee projected coming years, urgent need to balance it with appropriate use industrial application wastes by-products, which renewable resources rich carbohydrates, proteins, pectin, bioactive compounds (polyphenols). The applications described above, together those that will undoubtedly developed future, represent promising opportunities take advantage agro-industrial processing Coffea spp. develop more efficient sustainable systems through biorefinery approaches circular economy.

Neurodegenerative diseases, characterized by progressive loss in selected areas of the nervous system, are becoming increasingly prevalent worldwide due to an aging population. Despite their diverse clinical manifestations, neurodegenerative diseases multifactorial disorders with standard features and mechanisms such as abnormal protein aggregation, mitochondrial dysfunction, oxidative stress inflammation. As there no effective treatments counteract increasing interest has been directed potential neuroprotective activities plant-derived compounds found abundantly food agrifood by-products. Food waste extremely negative impact on environment, recycling is needed promote disposal overcome this problem. Many studies have carried out develop green strategies extract bioactive from by-products, peel, leaves, seeds, bran, kernel, pomace, oil cake, investigate biological activity.
