“…It can be seen that despite of some divergences in extraction kinetic curves, especially in the latter stage of ultrasound-assisted extraction, the diffusional model can satisfactorily describe the evolution of total phenolic yield during extraction with and without sonication. Similar results were also reported in the studies of Tao et al (2017) [24] and Ravi et al (2019) [38]. The low values of RMSE and E% (lower than 10%) and high R 2 value (higher than 0.93) listed in Table S2 all demonstrate the considerably high accuracy of diffusional modeling results.…”

Almond skin is an important by-product in the almond processing industry, rich in potentially health-promoting phenolic compounds. The objective of this present study is to separate the skin from the almond and extract its polyphenol contents using Ultrasound-Assisted Extraction (UAE) at room temperature. Optimization was performed according to a two-variable central composite design (CCD), and the optimum combination of ultrasonic intensity and extraction temperature was obtained through multi-response optimization: ultrasonic intensity (UI), 9.47 W.cm−2; and temperature, 20 °C for an extraction time of 20 min. Under the above-mentioned conditions, total phenolic content was 258% higher with UAE than silent experiment. Mathematic modelling and microscopic investigations were achieved to enable understanding physical and structural effects of ultrasound on almond skins and comprehension of the mechanism behind the enhancement of mass transfer phenomena. Scanning Electron Microscopy (SEM) showed different acoustic cavitation impacts including fragmentation, sonoporation, and erosion. Extracts were analyzed by ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS), identifying a combination of flavanols, flavanones and non-flavonoids. UAE shows no negative effect on almond proteins and lipids when compared to natural almonds (NS).

“…The current challenge in determining the functional properties of insects is the lack of standardization in protein isolation methods. Preliminary studies investigating the functional properties of select insect flours and proteins have found that the extraction method influenced the functionality of the extracted insect proteins (Amarender, Bhargava, Dossey, & Gamagedara, 2020;Bußler et al, 2016;Ravi et al, 2019). This was also seen to be true for BSFL, as it was established that the technofunctional properties of BSFL can be manipulated through processing and extraction methods (Bußler et al, 2016).…”

“…It was found that the high fat content in the BSFL flours negatively affected the functionality of the BSFL flour and reducing the fat content of the BSFL through various fat extraction techniques was seen to improve some of the functionality of the proteins (Bußler et al, 2016). Furthermore, the solvent used in the fat extraction was found to have an effect on BSFL's protein quality and after comparing multiple solvents, 2-methyloxolane was found to produce a protein of better quality (Ravi et al, 2019). BSFL have good lipid and water absorption capacities (Bußler et al, 2016), and these findings correlate well to that of other insect species, with studies indicating that they typically have high water and lipid absorption properties with some insect species having more desirable absorption properties than others (Omotoso & Adedire, 2007;Osasona & Olaofe, 2010;Womeni et al, 2012).…”

With the surge in consumption of insects, the search continues to find ways to increase the popularity of insect‐based products in the Western world. The black soldier fly larvae (BSFL), which is mainly utilized for animal feed, has great potential to provide a sustainable source of nutrients for human food. This review aims to discuss some of the key benefits and challenges of BSFL and their potential role as a food ingredient and/or product for human consumption. Few articles specifically discuss BSFL as a food source, therefore a comprehensive literature search strategy consisted of collecting and evaluating published data about BSFL as animal feed that could be relevant to its use in food. The hurdles that need to be overcome in order to introduce BSFL as a viable food option include safety concerns, technofunctional properties, nutritional aspects, consumer attitudes, and product applications for BSFL.

“…Industrial rearing, processing, and valorization of BSF for the obtention of proteins, lipids, chitin derivatives, bioactive peptides, organic manure, and other micro, macro-nutrients is an intricate task. It involves several unit operations, extraction and separation mechanisms, fractionation techniques and biorefining schemes for the exhaustive utilization of BSF biomass [9]. The inherent nature of BSF to aggregate select nutrients from the feed substrate [10] can be exploited to retrieve dilute constituents present in the diet.…”

Each year, the food supply chain produces more than 1.3 billion tons of food and agricultural waste, which poses serious environmental problems. The loss of the massive quantity of secondary and primary metabolites retrievable from this resource is a significant concern. What if there is a global solution that caters to the numerous problems arising due to the humongous volume of waste biomass generated in every part of the world? Insects, the tiny creatures that thrive in decaying organic matter, which can concentrate the nutrients present in dilute quantities in a variety of by-products, are an economically viable option. The bioconversion and nutritional upcycling of waste biomass with insects yield high-value products such as protein, lipids, chitin and frass. Insect-derived proteins can replace conventional protein sources in feed formulations. Notably, the ability of the black soldier fly (BSF) or Hermetia illucens to grow on diverse substrates such as agri-food industry side streams and other organic waste proves advantageous. However, the data on industrial-scale extraction, fractionation techniques and biorefinery schemes for screening the nutritional potential of BSF are scarce. This review attempts to break down every facet of insect processing and analyze the processing methods of BSF, and the functional properties of nutrients obtained thereof.
