“…Carbon dioxide (CO 2 ) is an outstanding solvent for SFE due to its chemical inactivity, economic accessibility, separability, non-toxicity, and food-grade status. Nonpolar gas-like and liquid-like supercritical CO 2 can extract heat-sensitive compounds (Gan and Baroutian 2022 ). To get the best outcomes during SFE, proper temperature, time, and pressure control is crucial to ensure optimal results (Ahangari et al 2021 ; Rochfort et al 2020 ).…”

A significant portion of the human diet is comprised of fruits, which are consumed globally either raw or after being processed. A huge amount of waste and by-products such as skins, seeds, cores, rags, rinds, pomace, etc. are being generated in our homes and agro-processing industries every day. According to previous statistics, nearly half of the fruits are lost or discarded during the entire processing chain. The concern arises when those wastes and by-products damage the environment and simultaneously cause economic losses. There is a lot of potential in these by-products for reuse in a variety of applications, including the isolation of valuable bioactive ingredients and their application in developing healthy and functional foods. The development of novel techniques for the transformation of these materials into marketable commodities may offer a workable solution to this waste issue while also promoting sustainable economic growth from the bio-economic viewpoint. This approach can manage waste as well as add value to enterprises. The goal of this study is twofold based on this scenario. The first is to present a brief overview of the most significant bioactive substances found in those by-products. The second is to review the current status of their valorization including the trends and techniques, safety assessments, sensory attributes, and challenges. Moreover, specific attention is drawn to the future perspective, and some solutions are discussed in this report.

Edible seaweeds are an excellent source of macronutrients, micronutrients, and bioactive compounds, and they can be consumed raw or used as ingredients in food products. However, seaweeds may also bioaccumulate potentially hazardous compounds for human health and animals, namely, heavy metals. Hence, the purpose of this review is to analyze the recent trends of edible seaweeds research: (i) nutritional composition and bioactive compounds, (ii) the use and acceptability of seaweeds in foodstuffs, (iii) the bioaccumulation of heavy metals and microbial pathogens, and (iv) current trends in Chile for using seaweeds in food. In summary, while it is evident that seaweeds are consumed widely worldwide, more research is needed to characterize new types of edible seaweeds as well as their use as ingredients in the development of new food products. Additionally, more research is needed to maintain control of the presence of heavy metals to assure a safe product for consumers. Finally, the need to keep promoting the benefits of seaweed consumption is emphasized, adding value in the algae-based production chain, and promoting a social algal culture.

“…One of the drawbacks of SFE is that several variables must be optimized to achieve acceptable yields [34]. Recently, SC-CO 2 extraction has been extensively used in lipid isolation from macroalgae [35][36][37][38][39]. However, the SC-CO 2 extraction of O. intermedium has not yet been investigated.…”

Macroalgae bioremediation is a potential way to deal with the escalating problem of arsenic contamination. The results of this study demonstrate that the arsenic content in wastewater treated by Oedogonium intermedium decreases by 32% from 1.13 ± 0.01 to 0.77 ± 0.03 ppb. Then, supercritical carbon dioxide (SC‐CO2) extraction was employed to isolate lipids from O. intermedium. Response surface methodology based on the Box‐Behnken design was carried out to optimize the SC‐CO2 extraction conditions of pressure (200–400 bar), temperature (30–50 °C), and extraction time (30–90 min). The optimal conditions from the model are predicted as 301.95 bar, 41.3 °C, and 30.53 min with 3.24 % lipid yield, 61.30 % PUFA ratio, and 0.106 µg g−1 of arsenic content, respectively.
