“…According to previous research, it was found that microencapsulated samples with coffee oil had a higher antioxidant activity than samples without coffee oil. Previous experiments and research also included in vitro testing of SCG oil and showed good antioxidant activity and cytotoxic effects on skin and liver cells [ 39 , 40 ].…”

Background: Following petroleum, coffee ranks as the second most extensively exchanged commodity worldwide. The definition of spent coffee ground (SCG) can be outlined as the waste generated after consuming coffee. The aims of the study are to produce edible/biodegradable packaging with the addition of spent coffee grounds (SCG) oil and to investigate how this fortification can affect chemical, textural, and solubility properties of experimentally produced films. Methods: The produced films were based on κ-carrageenan and pouring–drying techniques in petri dishes. Two types of emulsifiers were used: Tween 20 and Tween 80. The films were analyzed by antioxidant and textural analysis, and their solubility was also tested. Results: Edible/biodegradable packaging samples produced with the addition of SCG oil showed higher (p < 0.05) antioxidant capacity in comparison with control samples produced without the addition of SCG oil. The results of the research showed that the fortification of edible/biodegradable packaging with the addition of SCG oil changed significantly (p < 0.05) both chemical and physical properties of the films. Conclusions: Based on the findings obtained, it was indicated that films manufactured utilizing SCG oil possess considerable potential to serve as an effective and promising material for active food packaging purposes.

“…[41][42][43]. According to the literature, the lipid content of CS and SCG depends on the brewing and extraction methods with values ranging from 1.6% to 3.4% and 10 to 15%, respectively, being triacylglycerols the main components of the oils [2,11,13,42,44].…”

“…The price/quotation of the coffee bag in July 2020 was approximately US$ 100 in Brazil, which is the largest exporter of coffee in the world and occupies the second position among the consuming countries of this beverage [1]. Consequently, different by-products are produced during coffee processing (e.g., husks and mucilages), coffee roasting (e.g., coffee silverskin) and coffee drink preparation (spent coffee grounds) [2][3][4][5]. The current policies seek to prevent and reduce waste generation, with the proposal of practicing sustainable consumption habits and reusing waste.…”

“…The current policies seek to prevent and reduce waste generation, with the proposal of practicing sustainable consumption habits and reusing waste. Growing environmental awareness has triggered an interest in the valorization of agro-food and organic wastes which are generated in large amounts daily, such as spent coffee grounds (SCG) and coffee silverskin (CS), to produce added-value products [2,[4][5][6]. This concept has been used by many countries in the development of integrated biorefineries.…”

Synthesis of Dietetic Structured Lipids from Spent Coffee Grounds Crude Oil Catalyzed by Commercial Immobilized Lipases and Immobilized Rhizopus oryzae Lipase on Biochar and Hybrid Support

et al. 2020

The aim of this study was the valorization of coffee industry residues, namely spent coffee grounds (SCG) as a source of oil, and silverskin (CS) as a source of both oil and biomass, under the concept of the circular economy. Therefore, crude oil from SCG was used to produce low-calorie structured lipids (SL) for food and pharmaceutical industries, and CS to produce biochar by pyrolysis for biotechnological uses. SL were obtained by acidolysis with caprylic or capric acid, or interesterification with ethyl caprylate or ethyl caprate, in solvent-free media, catalyzed by immobilized sn-1,3 regioselective lipases. Silverskin biochar (BIO) was directly used as enzyme carrier or to produce hybrid organic-silica (HB) supports for enzyme immobilization. Rhizopus oryzae lipase (ROL) immobilized on Amberlite (AMB), silica (SIL), BIO or HB, and the commercial immobilized Thermomyces lanuginosus (Lipozyme TL IM) and Rhizomucor miehei (Lipozyme RM IM) lipases were tested. Lipozyme RM IM showed better results in SL production than Lipozyme TLIM or ROL on BIO, SIL or HB. About 90% triacylglycerol conversion was attained after 7 h acidolysis or interesterification. Lipozyme RM IM was more stable in interesterification (80% and 65% activity with ethyl caprylate or ethyl caprate) than in acidolysis (first-order decay) after 10 reuses.

“…Spent coffee grounds (SCG) are the solid-waste products of coffee consumption. Six million tons of coffee grounds are produced per day worldwide [ 17 ]. As a result, large quantities of SCG are incinerated, and stored in landfills, potentially releasing harmful substances such as polyphenol and tannin into the environment.…”

Spent Coffee Grounds as Building Material for Non-Load-Bearing Structures

et al. 2022

View full text Add to dashboard Cite

The gradual development of government policies for ecological transition in the modern construction sector leads researchers to explore new alternative and low environmental impact materials with a particular focus on bio-sourced materials. In this perspective, the mechanical, thermal insulation, and the sound absorption performances of a spent coffee grounds/potato starch bio-based composite were analyzed for potential application in buildings. Based on thermal conductivity and diffusivity tests, the coffee grounds waste biocomposite was characterized as an insulating material comparable with conventional thermal insulation materials of plant origin. Acoustical tests revealed absorption coefficients in the same range as other conventional materials used in building acoustical comfort. This bio-sourced material presented a sufficient compressive mechanical behavior for non-load-bearing structures and a sufficient mechanical capacity to be shaped into building bricks. Mechanical, thermal, and acoustic performances depend on the moisture environment. The groundwork was laid for an initial reflection on how this composite would behave in two opposite climates: the continental climate of Reims in France and the tropical climate of Belém in Brazil.
