“…On the other hand, regarding bound phenolic extracts, durum wheat bran had a greater antioxidant activity than rice bran, both with DPPH and ABTS tests. It was also confirmed that the antioxidant capacity of cereal grains, in both in vitro and in vivo studies, is mainly due to the presence of the ferulic and phenolic acids in extracts' composition [65]. Furthermore, there are data showing the possible antioxidant effects of wheat bran phenolics on humans due to their relatively good absorption rate [66].…”

“…Additionally, they remarked that p-coumaric, ferulic, and cinnamic acids from corn bran extracts inhibited the production of nitric oxide (NO) by reduction in nitric oxide synthase (iNOS) expression in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages [64]. Another novel relevant study performed by Guerrini et al [65] evaluated the antioxidant activity of durum wheat bran and rice bran using two techniques-DPPH and ABTS radical scavenging assays. The results showed that, according to both tests, when the content of free phenolic molecules was equivalent, rice bran had a greater antioxidant activity than wheat bran.…”

In today’s society, we can see a progressive paradigm shift that tends towards a healthy and sustainable lifestyle. The proof is represented by the growing interest in food loss and waste of different sectors, from the political to the academic, or even to the private sector. In order to reduce food waste and to increase sustainability, the European Union (EU) has planned a circular bioeconomy. This action plan includes an approach based on reducing, reusing, recovering, and recycling materials and energy. Every year, there are high amounts of waste and by-products resulting from agricultural producing and agro-industrial processing, impacting the environment and the socio-economic sector. Cereal food products cover over 20% of daily diet, so it can be assumed that cereal production and processing are one of the most important sectors of agri-food industries. It is estimated that the waste generated from cereal processing and manufacturing is up to 13%, a percentage that can be decreased by converting the by-products in raw materials for biofuels, biodegradable plastics, alcohols, antioxidants, food additives, or pharmaceutic ingredients due to their content in macro- and micro-nutrients or bioactive compounds. Based on the fact that diet plays a crucial role in maintaining the integrity of our body, it is important to capitalize on any source of bioactive compounds to which we have access. This review aims to highlight the need to recirculate by-products for the purpose of extraction and use of their key compounds, polyphenols, which have not only antioxidant effects, but also preventive and therapeutic effects against cancer. For these, it is necessary to understand the biotechnologies needed for processing the most consumed cereals, the methods of extraction of phenolic compounds, and the main effects that these compounds have, summarizing the most relevant in vitro and in vivo studies performed so far.

“…In the recent decades, the number of studies recovering antioxidants and other bioactive compounds from agricultural waste has increased significantly, due to the variety of biological properties attributed to the compounds but also to give added value to these matrices [232]. Most of these studies are focused on the evaluation of biological properties of extracts and compounds obtained from diverse agricultural waste; the use of nonconventional techniques, the improvement of extraction yields, and the reduction of cost and environmental impact, comparing with the conventional techniques; and also optimize the extraction conditions of certain compounds [233][234][235]. However, although the scientific community has widely described the benefits of waste re-valorization strategies to obtain extracts rich in bioactive compounds to develop new industrial products, its application at industrial-scale is still limited by several aspects, some of them will be mentioned below.…”

The increasing world population entails a great necessity to produce large amounts of food, leading to an increase in organic waste. Unlike traditional agriculture, based on the circular sustainability, modern agriculture produces tons of residues, which are accumulated in landfills or, in some cases, burnt. Numerous studies have demonstrated that agricultural residues are rich in bioactive compounds, particularly phenolic compounds, with antioxidant properties. Antioxidant activity has been widely related with protective effects and prevention potential for different diseases. Also, the scavenging and protective effects of antioxidant compounds have shown a connection and synergistic effect with other biological properties, such as anti-inflammatory, anti-tumor, anti-aging, neuroprotective, cardioprotective, or antidiabetic. These compounds can be applied in several fields, including food, cosmetic, and pharmaceutical industry. This chapter will be focused on the interconnected bioactive properties and possible applications of plant-origin compounds with antioxidant potential to valorize different agricultural waste.

As food consumption increases, so does the number of agricultural by-products. That is why it is necessary to find the best possible uses for them, operating by the principles of the bioeconomy. This work aims to gather information on the possibilities of using grain byproducts to develop new products and evaluate which bran products are the most suitable for commercialisation based on economic, environmental, social, and technical factors. Two methods were used in this work: literature review and multi-criteria decision analysis. As a result, 30 products were identified that could be made by using wheat bran, straw, husk, and dust. The products were divided into six groups – packaging materials, building materials, adsorbents, fuel, thermal insulation materials, and chemicals. In multi-criteria decision analysis, it was looked at seven bran products of which the best alternative for further commercialisation is mycelium-based biocomposite.
