“…The vegetables and fruits tested in this trial are some of the richest in what concerns total phenolic content [ 65 , 66 ]. However, each one had its own qualitative profile and it is possible that the three substrates with worst performances—apple, grape pomace, and spinach—contain anti-nutritional phenolic properties.…”

Among the insect species reared as alternative protein sources, Hermetia illucens (black soldier Fly, BSF) has shown a huge potential mostly due to its high protein content, its bioconversion rates, and versatility in using different feeding substrates. Insect rearing may use continuous or batch feeding regimes and, among the used substrates, supermarket feedstock waste has gained recent interest under a circular economy perspective, but several uncertainties remain regarding the heterogeneity and the potential effects of the quantity and quality of these substrates on BSF larvae (BSFL) development. In this experimental work, five replicates of a hundred BSFL were fed in a continuous feeding regime, using seven different isolated vegetables as substrates (wheat bran, pumpkin, apple, grape pomace, red onion, red cabbage, and spinach), at three different temperatures (20, 25, and 30 °C) and two substrate moisture conditions (natural and 70% substrate moisture), until 50% of the larvae achieved the prepupal stage. BSFL performance and bioconversion parameters were evaluated. Our results show that some substrates should be avoided when rearing Hermetia illucens on feedstocks. Among these, apple feed led to poorer and slower development performances with more than 100 days of larval stage, while grape pomace and spinach showed higher mortality rates, which may be due to some anti-nutritional compounds. Larvae fed on pumpkin, red cabbage, and red onion presented good bioconversion results with higher values of efficiency of conversion of digested feed between 14.4 and 25. This work delivers relevant results for black soldier fly reared on a continuous feeding system using vegetable feedstock substrates and their potential trade-offs.

Peanuts (Arachis hypogea) can be made into various products, from oil to butter to roasted snack peanuts and candies, all from the kernels. However, the skin is usually thrown away, used as cheap animal feed, or as one of the ingredients in plant fertilizer due to its little value on the market. For the past ten years, studies have been conducted to determine the full extent of the skin’s bioactive substance repertoire and its powerful antioxidant potential. Alternatively, researchers reported that peanut skin could be used and be profitable in a less-intensive extraction technique. Therefore, this review explores the conventional and green extraction of peanut oil, peanut production, peanut physicochemical characteristics, antioxidant activity, and the prospects of valorization of peanut skin. The significance of the valorization of peanut skin is that it contains high antioxidant capacity, catechin, epicatechin resveratrol, and procyanidins, which are also advantageous. It could be exploited in sustainable extraction, notably in the pharmaceutical industries.

In recent years, there has been a growing interest in harnessing the potential of bioactive compounds sourced from specific wild plants with inherent natural anti-inflammatory properties. Inflammation is a complex physiological response crucial for defense against adverse stimuli. However, prolonged inflammation can give rise to a myriad of health issues, particularly when influenced by factors related to mineral exposure and processing. This review aims to provide an overview of the current status of knowledge regarding the anti-inflammatory plant-based drugs which have been derived from green tea, licorice, devil's claw, willow bark, chamomile, Salvia officinalis and Piper ovatum etc. Bioactive compounds such as catechins, glycyrrhizin, harpagoside, salicin, chamazulene, Lactones and alkaloids which are referred as secondary plant metabolites obtaining the pharmacological effects in human beings and animals. It has long been identified by the authors of various classical texts of Ayurveda and their properties, indications to inhibit the production of pro-inflammatory cytokines and enzymes which helps to modulate various signaling pathways involved in inflammation. This study delves into the assessment of the anti- inflammatory properties of select wild plants while taking into consideration their potential interactions with mineral and mineral-associated pollutants. Safety and potential side effects are discussed in the context of metal exposure scenarios. Additionally, it underscores the necessity for continued research to elucidate the action mechanisms of these plant-derived compounds, further unlocking their therapeutic potential and efficacy in addressing inflammation heightened by mineral- related factors.
