“…In addition, higher levels of phenolics, flavonoids, and biotransformed substances were identified. The fermentation of other soy by-products, such as meal, whey, and hull, has demonstrated vast potential for enhancing the bioactivity of the final products [165][166][167][168][169][170][171].…”

The valorization of agri-food by-products is essential from both economic and sustainability perspectives. The large quantity of such materials causes problems for the environment; however, they can also generate new valuable ingredients and products which promote beneficial effects on human health. It is estimated that soybean production, the major oilseed crop worldwide, will leave about 597 million metric tons of branches, leaves, pods, and roots on the ground post-harvesting in 2020/21. An alternative for the use of soy-related by-products arises from the several bioactive compounds found in this plant. Metabolomics studies have already identified isoflavonoids, saponins, and organic and fatty acids, among other metabolites, in all soy organs. The present review aims to show the application of metabolomics for identifying high-added-value compounds in underused parts of the soy plant, listing the main bioactive metabolites identified up to now, as well as the factors affecting their production.

“…Devido sua alta demanda o processamento industrial destes cereais gera uma grande quantidade de subproduto. O farelo de trigo representa cerca de 15% da massa total do grão, além disso, é constituído por 23,7% de hemicelulose, 11% de celulose e 3,6% de lignina e composto por proteína bruta (17,4%), extrato etéreo (2,1%), fibra bruta (7,2%) e cinzas (4,2%) (Kupski et al, 2018). O farelo de arroz representa cerca de 8,5-14,8% da massa do grão (Walter, Marchezan, & de Avila, 2008) cerca de 180.000 toneladas métricas de farelo de arroz são geradas por ano (Rashid et al, 2015).…”

Os compostos fenólicos são encontrados em diversas matrizes, como nos resíduos agroindustriais. No entanto, podem estar associados a macromoléculas, reduzindo sua disponibilidade. Desta maneira, a fermentação em estado sólido (FES) torna-se uma alternativa promissora para a disponibilização destes compostos em resíduos agroindustriais. O objetivo desta revisão bibliográfica foi identificar na literatura identificar na literatura disponível o uso de resíduos agroindustriais de cereais e leguminosas na fermentação em estado sólido para produção de compostos fenólicos. Como referências de base de dados eletrônicas foram utilizadas as plataformas SCIELO, WEB OF SCIENCE, SCOPUS e SCIENCE DIRECT, analisando estudos publicados nos anos de 2015, 2016, 2017, 2018 e 2020; usando as seguintes palavras chaves: Compostos fenólicos (Phenolic Compounds), Fermentação em estado sólido (Solidstate fermentation), Resíduos agroindustriais (Agro-industrial wastes), Resíduos agroindustriais cereais (Agro-industrial wastes cereals), Resíduos agroindustriais leguminosas (Agro-industrial wastes leguminous), Produção (Production), Síntese Synthesis), flavonóides (Flavonoids), Ácidos fenólicos (Phenolic acids) e Disponibilidade (Availability). Foram selecionados 23 artigos, entre os anos de 2015 a 2020, para avaliar as condições de fermentação mais empregadas para disponibilizacao de compostos fenólicos. Destes estudos 19 referem-se à fermentação de resíduos de cereais e o restante (4), a fermentação de resíduos de leguminosas. O microrganismo mais utilizado foi o fungo filamentoso Aspergillus oryzae. De modo geral, a utilização de resíduos agroindustriais como substratos em fermentação em estado sólido para aumentar a disponibilização de compostos bioativos representa mais uma rota tecnológica em experimentação e que está em grande evolução, o que pode futuramente, diminuir substancialmente os custos de produção, reduzir o acúmulo destes materiais no meio ambiente e agregar valor nestes materiais que antes eram desvalorizados.

“…Lignocellulosic is a reliable resource for biorefinery (Huijgen et al 2012). The three main components of lignocellulose are cellulose (β -1,4-linked glucose polymer) hemicellulose (polymer containing hexose & pentose) and lignin (phenol cross-linked polymer) (Galletti et al 1991;Kupski et al 2018). These three components make up the cell wall which acts as a physical barrier aimed to protect the inner tissues (Kupski et al 2018).…”

This study illustrates the potential opportunity for the utilization of hemp to produce PHB (poly(3-hydroxybutyrate). The objective of the study was to optimize simple sugar availability from hemp for Ralstonia eutropha. The use of three pre-treatment methods (grinded – 5% NaOH – Autoclave at 121 oC for 60 minutes) was able to provide a better fractional insoluble solids (FIS) of ≃ 61 % that was significantly better compared to other combinations of pre-treatments studied. Optimum enzyme dosage was also determined by comparing different enzyme concentrations and found that three enzymes should contain a dose of 1.5 g /L. The optimum pretreatment and hydrolysis conditions resulted in a better enzyme hydrolysis yield of 10.9 % and PHB yield of ≃ 43 %. Results also demonstrate that sonification did not improve PHB recovery, while pH control increased PHB recovery. Keywords: Hemp, Ralstonia eutropha, PHB, Pre-treatment, Enzyme Hydrolysis
