“…Putnik et al [ 6 ], reviewed these alternative valorization options for orange pomace which include production of antioxidants, edible fibres, pectin, essential oil, enzymes, bioethanol, electric acid, biogas and use of the pomace as soil improvement material or animal feed. Martinez-Hernandez et al [ 7 ] studied in detail the techno-economic and environmental aspects of the energy valorization of orange peel waste for steam generation and concluded that this is feasible at industrial scale provided a minimum of 500 t/d orange peel processing capacity is used. According to their results, strategies such as stream energy recovery, excess ratio optimization, as well as water and value-added chemical recovery are recommended to develop synergetic relationships in the energy–water nexus of the conversion of orange peels into energy.…”

“…In addition, concerning the phenolic content of orange pomace, it contains polyphenols belonging mainly to the class of flavonoids and in particular flavones, flavonols, flavonons, isoflavons, anthocynidines and flavanols. The main flavonoids of orange fruit are hesperidin, narirutin, eriocitrin, naringin, neohesperidin, neoeriocitrin and among them hesperidin and narirutin are dominant [ 7 , 8 , 9 ]. Also, a series of short-chain bioactive phenolic acids including caffeic, chlorogenic, ferulic, sinapic and p-cumaric reported to be constituents of the phenolic profile of orange pomace [ 10 ].…”

Optimization of Vacuum-Microwave-Assisted Extraction of Natural Polyphenols and Flavonoids from Raw Solid Waste of the Orange Juice Producing Industry at Industrial Scale

et al. 2021

Orange pomace (OP) is a solid waste produced in bulk as a byproduct of the orange juice industry and accounts for approximately 50% of the quantity of the fruits processed into juice. In numerous literature references there is information about diverse uses of orange pomace for the production of high-added-value products including production of natural antioxidant and antimicrobial extracts rich in polyphenols and flavonoids which can substitute the hazardous chemical antioxidants/antimicrobials used in agro-food and cosmetics sectors. In this work and for the first time, according to our knowledge, the eco-friendly aqueous vacuum microwave assisted extraction of orange pomace was investigated and optimized at real industrial scale in order to produce aqueous antioxidant/antimicrobial extracts. A Response Surface Optimization methodology with a multipoint historical data experimental design was employed to obtain the optimal values of the process parameters in order to achieve the maximum rates of extraction of OP total polyphenols and/or total flavonoids for economically optimum production at industrial scale. The three factors used for the optimization were: (a) microwave power (b) water to raw pomace ratio and (c) extraction time. Moreover, the effectiveness and statistical soundness of the derived cubic polynomial predictive models were verified by ANOVA.

“…The price for the destination ranges, respectively, from US$ 25 to 35/m 3 and US$ 40.92 to 73.03/tonUS$ 4 . Orange by‐products can be up to 50–60% of the processed fruit, of which 60–65% is composed of orange peels (OP) (30–35% of internal tissue and the rest are seeds) 5,6 . Orange peel composition includes fats, structural (cellulose, hemicellulose, and pectin) and non‐structural (free sugars) carbohydrates, organic acids, essential oils (mainly limonene), and flavonoids 7‐10 …”

An economic evaluation was conducted of flavanone and sugar production from orange peel (OP) using a sequential hydrothermal process. The process was conducted at laboratory (2 × 5 L), pilot (3 × 10 L), and industrial (3 × 500 L) scales. The results demonstrate that the scale‐up process decreased the cost of manufacturing (COM) with a significant increase in flavanone and sugar production. The lowest COM was of US$ 25.72/kg flavanones and US$ 1.43/kg sugars, both on an industrial scale. The predominant costs at the industrial scale (>90%) were the cost of utilities and the cost of raw materials. A low capital payback time was obtained, which decreased as return on investment and gross margin increased. A strengths, weaknesses, opportunities, and threats matrix demonstrates the relevant business topics related to the scale‐up of OP processing. Thus, the current scale‐up project can be considered as a promising approach to the production of flavanones and sugar from OP on an industrial scale. © 2020 Society of Industrial Chemistry and John Wiley & Sons Ltd

“…O setor de agronegócios está em crescente desenvolvimento para atender a demanda populacional em relação à alimentação (Santos, Dweck, Viotto, Rosa, & de Morais, 2015;Sial et al, 2019). Uma das principais atividades agroindustriais, em âmbito global, é a produção de laranja, tanto para o processamento do suco quanto para outros co-produtos, ficando em quinto lugar como uma das frutas mais produzidas (Martinez-Hernandez et al, 2019;Calabrò, Paone, & Komilis, 2018).…”

“…Segundo a Organização das Nações Unidas para Agricultura e Alimentação (FAO), a produção mundial de laranja em 2017 foi de 82 milhões de toneladas (KWON et al, 2019). Salienta-se que a produção de laranja concentra-se principalmente no Brasil, Estados Unidos da América, China, Índia e México (MARTINEZ-HERNANDEZ et al, 2019).…”

A produção de laranja é uma das principais atividades da agroindústria no mundo, sendo fabricado mais de 80 milhões de toneladas anuais. Consequentemente, resíduos orgânicos são gerados e, muitas vezes, seu descarte inadequado corrobora para o aumento da degradação ambiental. Diante deste contexto, coletou-se dados do consumo de laranjas e do descarte das cascas através da visita ao restaurante Hoffmann (Florianópolis/SC) e borra de café do restaurante Tio João. Posteriormente, foi desenvolvido briquetes a partir destes resíduos, e avaliado o poder calorifico superior e inferior, resistência mecânica a tração, monitoramento de fumaça e cinzas, mostrando que os corpos de prova mais resistentes foram os que tiveram maior quantidade de casca de laranja. Quanto ao teor de cinzas encontrado nos espécimes foram de 4,89 a 5,63% e, por fim, o teste de sílica demonstrou oscilações nos resultados entre os espécimes. Os briquetes desenvolvidos podem ser uma possibilidade para a reutilização dos resíduos da casa de laranja e borra de café como substituto da lenha mitigando os problemas ambientais globais desencadeados por emissões de CO2.
