The world is confronted with the depletion of natural resources due to their unsustainable use and the increasing size of populations. In this context, the efficient use of by-products, residues and wastes generated from agro-industrial and food processing opens the perspective for a wide range of benefits. In particular, legume residues are produced yearly in very large amounts and may represent an interesting source of plant proteins that contribute to satisfying the steadily increasing global protein demand. Innovative biorefinery extraction cascades may also enable the recovery of further bioactive molecules and fibers from these insufficiently tapped biomass streams. This review article gives a summary of the potential for the valorization of legume residual streams resulting from agro-industrial processing and more particularly for pea, green bean and chickpea by-products/wastes. Valuable information on the annual production volumes, geographical origin and state-of-the-art technologies for the extraction of proteins, fibers and other bioactive molecules from this source of biomass, is exhaustively listed and discussed. Finally, promising applications, already using the recovered fractions from pea, bean and chickpea residues for the formulation of feed, food, cosmetic and packaging products, are listed and discussed.

“Pacifism + non-resistance are by-products of some central things to which we have to testify.”Richard RobertsAlthough Rev. Richard Roberts was the chairman of the founding conference of the Fellowship of Reconciliation (FOR) at Cambridge in 1914, its first general secretary, and the key figure in its early ideology, he has largely been ignored in the secondary literature. Admittedly, Vera Brittain, in The Rebel Passion, sketched an appreciative vignette, but Jill Wallis, in her more recent FOR study Valiant for Peace, mentions him only six times without discussing his ideas. Even Roberts' daughter Gwen's biography, Grace Unfailing, fails to analyze the basis of his contribution. Yet, seven decades after attending the founding FOR conference, its only survivor, Horace Alexander, wrote that, while he could not recall the details, Richard Roberts had impressed him most, for he “got right into [him], and helped [him] find a sure foundation for life.” Alexander's comment points in the direction Martin Ceadel began to develop when he defined pacifism as a faith. But Ceadel restricted that faith to its relation to war, a restriction that was inappropriate for the early FOR. Pacifism, its leading members posited, should pervade all of life, private as well as public. Their conception of the new organization sounded like a worldview, a framework through which they viewed the world. Nevertheless, although pacifism should influence all of life, it was, as Roberts suggested, a by-product rather than the central element. Hence, rather than explicating his understanding of pacifism, at the founding conference Roberts focused on Christ's atonement as the ground of all ethics and as supplying the regulative principle of the Christian's reconciling ministry in the world. From this perspective he drew the conclusion that reconciliation implied a wide range of social activities for which the energies of youth, being used in warfare, should be mobilized in something akin to a Franciscan tertiary order. It was this call for social regeneration combined with evangelism that impressed Alexander. Only in passing Roberts declared the “simple,” pre-1914 pacifism bankrupt, while expecting that reconciliation in all spheres of life would undercut the commonly held view that war was “a hateful affair yet a noble enterprise of Christian chivalry.” This notion of reconciliation, with all that it entailed, became central. Even before the FOR had a conscription committee it had established committees for its rehabilitation of young offenders commune, for education, and for social service. The limited secondary literature has generally ignored these committees and failed to analyze the notion of reconciliation, focusing instead on the by-product and on conscientious objectors. Methodologically, Ceadel defined the FOR as quietist, and compared to the No-Conscription Fellowship (NCF) that would be quite accurate. Indeed, for while the FOR encouraged its members to be politically involved—it had a political group committee—it shied away from being a political pressure group, regarding the NCF tactics incompatible with reconciliation. Although its methodology was quietist, its ideology was radical, aiming at the transformation of society. In order to understand this largely Roberts-influenced reconciliation ideology, it is necessary to take a closer look at Roberts' worldview.

Microalgae are microscopic plants inhabiting the world?s oceans and other aquatic environments. They are critical for the health of the planet, being responsible for at least half of the global primary productivity. Like other photosynthetic (autotrophs) organisms, microalgae capture solar radiation and convert it to chemical energy as biomass, forming the basis of aquatic food webs, fixing carbon dioxide and producing oxygen as part of the process. Other microalgae (heterotrophs) can utilise organic compounds for growth. As single-celled packages of bioactive molecules that can be cultured to produce high levels of biomass, microalgae are a renewable resource with a wide range of applications in bioindustry. Their use is established in the human nutraceutical industry with ?super foods? such as Spirulina from the cyanobacterium (blue green alga) Arthrospira platensis (Figure 1). Intense interest surrounds the development of microalgae as a source of biofuels, and in the mitigation of CO2 and other greenhouse gases (GHG). Other bioactive compounds, as well as genes from microalgae, offer new opportunities for bioindustry.

AbstractWe review the principles of ultraviolet (UV) irradiation, the inactivation of infectious agents by UV, and current applications for the control of microorganisms. In particular, wavelengths between 200 and 280 nm (germicidal UV) affect the double-bond stability of adjacent carbon atoms in molecules including pyrimidines, purines and flavin. Thus, UV inactivation of microorganisms results from the formation of dimers in RNA (uracil and cytosine) and DNA (thymine and cytosine). The classic application of UV irradiation is the inactivation of microorganisms in biological safety cabinets. In the food-processing industry, germicidal UV irradiation has shown potential for the surface disinfection of fresh-cut fruit and vegetables. UV treatment of water (potable and wastewater) is increasingly common because the process is effective against a wide range of microorganisms, overdose is not possible, chemical residues or by-products are avoided, and water quality is unaffected. UV has been used to reduce the concentration of airborne microorganisms in limited studies, but the technology will require further development if it is to gain wider application. For bioaerosols, the primary technical challenge is delivery of sufficient UV irradiation to large volumes of air, but the absence of UV inactivation constants for airborne pathogens under a range of environmental conditions (temperature, relative humidity) further compounds the problem.

India is one of the largest producers of fruits and vegetables in the world. These are rich sources of bioactive compounds which provide health benefits and also possess antioxidant therapeutic value. A large portion of fruits and vegetables goes unutilized in the form of pulp and peels after the extraction of juice in food processing industries. This contains a large number of bioactive compounds. The compounds like phenolic compounds, flavonoids and carotenoids are ubiquitously present in fruits, vegetables and their by-products. These compounds have antioxidant, antimicrobial, anticancer, antiviral, antitumor and many more activities to a greater or lesser extent. This review focuses on the bioactive compounds present in fruits, vegetables and their by-products along with their classification and importance in day to day life. A further aim of this review is to discuss various techniques employed in the extraction of bioactive compounds from plant products. The antioxidant activity of various fruits and vegetables based on DPPH radical scavenging methods has also been reported in this work.

In recent years, modelling techniques have become more frequently adopted in the field of food processing, especially for cereal-based products, which are among the most consumed foods in the world. Predictive models and simulations make it possible to explore new approaches and optimize proceedings, potentially helping companies reduce costs and limit carbon emissions. Nevertheless, as the different phases of the food processing chain are highly specialized, advances in modelling are often unknown outside of a single domain, and models rarely take into account more than one step. This paper introduces the first high-level overview of modelling techniques employed in different parts of the cereal supply chain, from farming to storage, from drying to milling, from processing to consumption. This review, issued from a networking project including researchers from over 30 different countries, aims at presenting the current state of the art in each domain, showing common trends and synergies, to finally suggest promising future venues for research.

Seafood by-products, produced by a range of different organisms, such as fishes, shellfishes, squids, and bivalves, are usually discarded as wastes, despite their possible use for innovative formulations of functional foods. Considering that “wastes” of industrial processing represent up to 75% of the whole organisms, the loss of profit may be coupled with the loss of ecological sustainability, due to the scarce recycling of natural resources. Fish head, viscera, skin, bones, scales, as well as exoskeletons, pens, ink, and clam shells can be considered as useful wastes, in various weight percentages, according to the considered species and taxa. Besides several protein sources, still underexploited, the most interesting applications of fisheries and aquaculture by-products are foreseen in the biotechnological field. In fact, by-products obtained from marine sources may supply bioactive molecules, such as collagen, peptides, polyunsaturated fatty acids, antioxidant compounds, and chitin, as well as catalysts in biodiesel synthesis. In addition, those sources can be processed via chemical procedures, enzymatic and fermentation technologies, and chemical modifications, to obtain compounds with antioxidant, anti-microbial, anti-cancer, anti-hypertensive, anti-diabetic, and anti-coagulant effects. Here, we review the main discards from fishery and aquaculture practices and analyse several bioactive compounds isolated from seafood by-products. In particular, we focus on the possible valorisation of seafood and their by-products, which represent a source of biomolecules, useful for the sustainable production of high-value nutraceutical compounds in our circular economy era.
