IntroductionPeanut shells (PS) are abundant agro-industrial waste products that are recalcitrant to degradation under natural conditions [1]. The increasing expansion of peanut production has led to accumulation of large quantities of these shells all over the world. In the US alone, peanut production increased by 45% between 2011 and 2012, bringing production to 3.04 million metric tons [2]. Globally, 45.6 million metric tons of peanuts are produced annually [3]. It has been estimated that for every kg of peanuts produced, 230-300 g of peanut shells are generated [4]. Therefore, as much as 13.7 million metric tons of peanut shells are churned out every year, most of which are dumped into the environment or burned [5,6]. Peanut shells are a renewable resource that could be targeted for purposeful use in the food, feed, paper and bioenergy industries. However, as yet, few if any value-added uses exist for them [7].Over the years, various attempts to utilize peanut shells have been made. Small fractions were incorporated into animal feed, especially for cattle [8], while some authors have experimented on their use as dietary fiber for humans [9]. Other non-food research trials include uses in pulp production [10], feedstock for bioethanol production [11,12], particle board component [13], mulch and activated charcoal [7]. However, the major drawback to their use in large scale industrial operations is the high lignin content.Much like other agricultural lignocellulolysic biomass, peanut shells are composed mainly of lignin, cellulose and hemicellulose. Lignin, a complex polymer, is the most recalcitrant component of plant biomass [14] and binds tightly to, and provides a physical seal around, cellulose and hemicellulose [11,[15][16][17][18], thereby protecting them against attack by hydrolytic enzymes. The restricted bioavailability of these sugars and other components is thought to be largely physical, with lignin molecules reducing the surface area available to enzymatic penetration and activity [19]. In order to gain access to the sugars in cellulose and AbstractWorld consumption of peanuts has increased tremendously, resulting in abundance of peanut shell waste. The high lignin content of peanut shells limits their bioconversion to useful products or recycling. Therefore, the synergy in co-substrating peanut shells (PS) and cornstalks (CS) to enhance biodegradation was evaluated. Various compositions of peanut shells and cornstalks (% dry weight) herein called co-substrate -90PS:10CS, 75PS:25CS, 50PS:50CS, 25PS:75CS, 10PS:90CS, and two controls Cont1-100PS and Cont2-100CS were studied under solid state fermentation (SSF) with a white rot fungus, Pleurotus ostreatus for 120 days. A two-factorial experiment in a completely randomized design (CRD) was used. Results showed that substrate composition and fermentation time were important variables in substrate degradation. Lignin degradation, losses in organic matter, cellulose and hemicellulose increased with time. Increasing the composition of CS in co-substrates...

“…In the scientometric analysis, papers were found using SCG and CH for the production of fungal biomass from Pleurotus ostreatus, Pleurotus eryngii, and other mushrooms [89,90]. The use of coffee by-products has shown to have an impact on the yield and quality of the edible fungi, and in some cases to increase the content of beneficial minerals like selenium, as mentioned earlier [68].…”

“…Regarding the application of CH in food products, only one paper was found which reported the cultivation of the fruiting bodies from the edible Basidiomycota fungi P. ostreatus. CH could serve as a substrate in which sodium selenite can be added and accumulated by the fungi, resulting in a food that could serve as a selenium supplement [68].…”

As coffee consumption is on the rise, and the global coffee production creates an excess of 23 million tons of waste per year, a revolutionary transition towards a circular economy via the transformation and valorization of the main by-products from its cultivation and preparation (Coffee Husk (CH), Coffee Pulp (CP), Coffee Silverskin (CS), and Spent Coffee Grounds (SCG)) is inspiring researchers around the world. The recent growth of scholarly publications in the field and the emerging applications of coffee by-products published in these scientific papers encourages a systematic review to identify the knowledge structure, research hotspots, and to discuss the challenges and future directions. This paper displays a comprehensive scientometric analysis based on 108 articles with a high level of influence in the field of coffee by-products and their applications. According to our analysis, the research in this field shows an explosive growth since 2017, clustered in five core applications: bioactive compounds, microbial transformation, environmental applications, biofuels from thermochemical processes, and construction materials.

Naringin from Coffee Inhibits Foodborne Aspergillus fumigatus via the NDK Pathway: Evidence from an In Silico Study

In the tropics, coffee has been one of the most extensively cultivated economic crops, especially Arabica coffee (Coffea arabica L.). The coffee pulp, which includes phytochemicals with a proven antifungal action, is one of the most insufficiently utilized and neglected byproducts of coffee refining. In the current experiment, we carried out in silico screening of the isolated Arabica coffee phytochemicals for antifungal activity against Aspergillus fumigatus: a foodborne fungus of great public health importance. As determined by the molecular docking interactions of the library compounds indicated, the best interactions were found to occur between the nucleoside-diphosphate kinase protein 6XP7 and the test molecules Naringin (−6.771 kcal/mol), followed by Epigallocatechin gallate (−5.687 kcal/mol). Therefore, Naringin was opted for further validation with molecular dynamic simulations. The ligand–protein complex RMSD indicated a fairly stable Naringin-NDK ligand–protein complex throughout the simulation period (2–16 Å). In ADME and gastrointestinal absorbability testing, Naringin was observed to be orally bioavailable, with very low intestinal absorption and a bioavailability score of 0.17. This was further supported by the boiled egg analysis data, which clearly indicated that the GI absorption of the Naringin molecule was obscure. We found that naringin could be harmful only when swallowed at a median lethal dose between 2000 and 5000 mg/kg. In accordance with these findings, the toxicity prediction reports suggested that Naringin, found especially in citrus fruits and tomatoes, is safe for human consumption after further investigation. Overall, Naringin may be an ideal candidate for developing anti-A. fumigatus treatments and food packaging materials. Thus, this study addresses the simultaneous problems of discarded coffee waste management and antifungal resistance to available medications.
