Insight into the proximate composition and microbial diversity of edible insects marketed in the European Union

Abstract: In recent years, the idea of exploiting edible insects for their industrial production has attracted the attention of media, research institutions and food industry operators, because of the numerous positive factors associated with this food source. Notwithstanding, insects are still underutilized in Western countries. Moreover, edible insects are carriers of natural microorganisms; hence, safety issues may arise from their industrial production. This study was aimed at providing insight into the proximate composition, with a focus in the fatty acid and amino acid composition, and microbial diversity of some processed edible insects marketed in the European Union. A high content of protein and fat was seen, with values ranging from 59.46 to 46.78 and 35.32 to 15.18%, respectively, with nutritionally valuable characteristics in both the lipid fractions and amino acid profiles. Furthermore, a great variation in microbial counts was seen. Both commensal and potential pathogenic microorganisms ascribed to the genera Pediococcus, Weissella, Streptomyces, Acinetobacter, Agrococcus, Arthrobacter, Naxibacter, Planomicrobium, Rufibacter, Bacillus, Clostridium, Vibrio, Desulfovibrio, Loktanella, Escherichia, Tetrapisispora, Aspergillus, Eurotium, Debaryomyces, and Wallemia, were identified by PCR-DGGE. The high diversity in the chemical composition and microbial profile of the marketed edible insects analyzed suggest a role of both the rearing and processing procedures on these variables. The results overall collected encourage the exploitation of edible insects as a valuable large-scale, animal-based commodity.

Marine Microbial-Derived Molecules and Their Potential Use in Cosmeceutical and Cosmetic Products

Abstract: The oceans encompass a wide range of habitats and environmental conditions, which host a huge microbial biodiversity. The unique characteristics of several marine systems have driven a variety of biological adaptations, leading to the production of a large spectrum of bioactive molecules. Fungi, fungi-like protists (such as thraustochytrids) and bacteria are among the marine organisms with the highest potential of producing bioactive compounds, which can be exploited for several commercial purposes, including cosmetic and cosmeceutical ones. Mycosporines and mycosporine-like amino acids, carotenoids, exopolysaccharides, fatty acids, chitosan and other compounds from these microorganisms might represent a sustainable, low-cost and fast-production alternative to other natural molecules used in photo-protective, anti-aging and skin-whitening products for face, body and hair care. Here, we review the existing knowledge of these compounds produced by marine microorganisms, highlighting the marine habitats where such compounds are preferentially produced and their potential application in cosmetic and cosmeceutical fields.

Development of a sustainable product lifecycle in manufacturing firms: a case study

Abstract: This study discusses a methodology for integrating Design for Environment (DfE) and life cycle assessment (LCA) techniques both into new product development and into the process of redesigning a set of existing products. The article explains the reasons for developing DfE in general, and pays particular attention to a specific, chosen product, a class of electrical distribution boards, to illustrate the concept. The main process steps in the development of the DfE are outlined, and the development of a LCA that satisfies the requirements of the ISO 14040 standard is illustrated. A major benefit of the DfE methodology proposed in this work is the possibility to use LCA data both during new product development and when modifying old products, with the aim of continuously reducing the overall environmental impact of products during their life cycle. This improvement cycle begins with the attempt to find new design solutions (for assembly and set-up in the case of electrical distribution boards), continues wi...
