“…Thus, there is a need to develop chemical assays to guarantee the maintenance of the raw material quality before being applied to the food industry to certify the quality and maintenance of the raw source, boosting the confidence of the final consumer. This can be achieved using software and rapid assessment techniques such as spectrophotometry, TLC and FTIR, which can be applied to software that can give similarity rates between samples, which can be used as material pre-testing before being approved and used in the food industry [117][118][119].…”

Diseases such as obesity; cardiovascular diseases such as high blood pressure, myocardial infarction and stroke; digestive diseases such as celiac disease; certain types of cancer and osteoporosis are related to food. On the other hand, as the world’s population increases, the ability of the current food production system to produce food consistently is at risk. As a result, intensive agriculture has contributed to climate change and a major environmental impact. Research is, therefore, needed to find new sustainable food sources. One of the most promising sources of sustainable food raw materials is macroalgae. Algae are crucial to solving this nutritional deficiency because they are abundant in bioactive substances that have been shown to combat diseases such as hyperglycemia, diabetes, obesity, metabolic disorders, neurodegenerative diseases and cardiovascular diseases. Examples of these substances include polysaccharides such as alginate, fucoidan, agar and carrageenan; proteins such as phycobiliproteins; carotenoids such as β-carotene and fucoxanthin; phenolic compounds; vitamins and minerals. Seaweed is already considered a nutraceutical food since it has higher protein values than legumes and soy and is, therefore, becoming increasingly common. On the other hand, compounds such as polysaccharides extracted from seaweed are already used in the food industry as thickening agents and stabilizers to improve the quality of the final product and to extend its shelf life; they have also demonstrated antidiabetic effects. Among the other bioactive compounds present in macroalgae, phenolic compounds, pigments, carotenoids and fatty acids stand out due to their different bioactive properties, such as antidiabetics, antimicrobials and antioxidants, which are important in the treatment or control of diseases such as diabetes, cholesterol, hyperglycemia and cardiovascular diseases. That said, there have already been some studies in which macroalgae (red, green and brown) have been incorporated into certain foods, but studies on gluten-free products are still scarce, as only the potential use of macroalgae for this type of product is considered. Considering the aforementioned issues, this review aims to analyze how macroalgae can be incorporated into foods or used as a food supplement, as well as to describe the bioactive compounds they contain, which have beneficial properties for human health. In this way, the potential of macroalgae-based products in eminent diseases, such as celiac disease, or in more common diseases, such as diabetes and cholesterol complications, can be seen.

The application of conventional flocculants always causes degenerative diseases, whereas natural polysaccharide (NPs)-based flocculants exhibit great potential, due to their biosafety. Considering material costs and sustainable development, NPs derived from waste have been extensively researched as a substitute for conventional flocculants, promoting the development of flocculation process toward safety, economy, and low-carbon direction. This review summarizes various waste polysaccharides (WPs) derived from ocean waste, agricultural waste, food waste, and invasive species. It then compares the treatment effects of typical WPs-based flocculants in water treatment. Flocculation mechanism of WPs-based flocculants was emphasized based on their respective structures and physicochemical properties. Moreover, flaws in WPs application have been noted, and strategies to deal with them have also been proposed. Benefiting from the environmental and economic benefits of WPs, the progress of using WPs-based flocculants is promising. However, some threats should be overcome, especially in terms of the stability and broad-spectrum applicability of WPs.

The dominant use of synthetic plastic derivatives is one of the major concerns across the world. The irrational use of plastic not only causes environmental pollution but also is reported to cause several health hazards. This has led researchers to develop biodegradable packaging materials derived from biomaterials. Polysaccharides are abundantly available biopolymers with excellent biodegradability. Marine animals are a vast source of obtained polysaccharides, including chitosan, hyaluronic acid, and chondroitin sulfate. The edible nature of the extracted marine-animal-derived polysaccharides makes it a useful alternative for synthetic derivatives in the food packaging industry. In addition, the antimicrobial and antioxidant behavior of marine-animalderived polysaccharides has favored its emergence as a packaging material. The film forming, protective, and excellent barrier property has encouraged the scientists to investigate them as food packaging materials. The easy modifiability of these polysaccharides can improve the film forming ability. This Article focuses on the recent advancements in marine animal derived polysaccharides in sustainable food packaging applications.
