The organic and plant-based hydrocolloids known for their antioxidant qualities, such as agar, carrageenan, and alginate, are made from edible seaweed. These serve as a clean label for the final products and are utilized in place of synthetic antioxidants. Since they can be employed as thickening, gelling, and emulsifying agents, hydrocolloids are widely used in the food and beverage industry to make processed foods. The majority of the remaining market share is accounted for by substances extracted from seaweeds, such as hydrocolloids, with the remainder going to lesser uses such as wastewater treatment, aquaculture, fertilizers, and additives for animal feed. Thus, growing consumer interest in natural ingredients and the various uses for materials obtained from Seaweed will drive the market for Seaweed.

Restraints of the Market

• The low concentration of certain amino acids (EAAs) in seaweed-

Seaweed's amino acid composition is influenced by several variables, including species, growth conditions, preservation techniques, extraction processes, and seasonal variations. Seaweeds are deficient in most essential amino acids, except those that contain sulfur. Critical amino acid availability and digestibility can have a significant impact on protein quality. Because animal protein sources include a high proportion of essential amino acids (EAA), which the human body is unable to generate, they are sometimes regarded as complete proteins. Conversely, plant proteins are often considered to be inadequate sources of protein due to the absence of one or more essential amino acids, including valine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, and taurine. Compared to common sources like corn and soy, seaweed has a considerably lower concentration of EAAS in its total biomass basis, which makes it inappropriate for use as a protein source in complex meals for animals with a single stomach. Amino acids such as lysine and tryptophan are frequently the limiting amino acids in the majority of seaweed species. Leucine and isoleucine are usually found in small amounts in red seaweed species, while methionine, cysteine, and lysine are often limited in brown seaweed species. This does not, however, take away from its advantageous health effects for people and animals, where its high mineral content and low-calorie content may be appealing.

• Climate change may impede the expansion of the Seaweed product industry-

Seaweed farming is primarily influenced by the temperature and moisture content of the air. The cultivation of seaweed is impacted by warm weather because it causes water to evaporate and inhibits the growth of thicker seaweed. On the other hand, moisture content is what gives seaweed its nutrients and minerals. Draughts and variations in freshwater salinity brought on by climate change cause seaweed to die, which reduces their ability to produce. Intense storms are also brought on by changes in rainfall patterns brought on by climate change. Seaweed production is hampered by this storm's source of runoff of vital nutrients from the farming ponds. Moreover, deep seawater from the ocean is forced to the surface by coastal upwelling, which brings nutrients from the ocean floor to the surface of the planet. Seaweed species that are collected from the sea bed are less productive as a result of this coastal upwelling. As a result, changing weather patterns have an impact on seaweed farming, which eventually limits market expansion.

Opportunities in the Market

• Rising veganism trends and increasing Attention to Environmental Sustainability in Support of Seaweed Production-

Environmental stress reduction methods have been developed as a result of increased global awareness of environmental challenges in recent years. Consumer preferences have changed significantly as a result of increased knowledge of environmental welfare, which is driving up demand for sustainable products. Because macro algae are nutrient-rich, fast-growing plants that both release and absorb carbon dioxide, their production is seen as sustainable. The increasing demand for plant-based goods that promote animal welfare and veganism is also linked to the growth in popularity of macroalgae cultivation.  The veganism trend is becoming increasingly popular among millennials and Gen Z demographics. Moreover, the emergence of plant-based foods is also due to rising awareness about plant-based protein and seaweed protein.
For instance, in May 2021, a survey by The Vegan Society found that one in four Brits conveyed that they had decreased the consumption of animal products since the start of the Covid-19 pandemic. 20 % of people said they reduced their meat consumption while 12% said they had lowered their eggs and dairy intake. 
Moreover, in 2021, the European Consumer Survey on Plant-based Foods, published by ProVeg International, stated that the UK's purchase and consumption rates of plant milk, meat alternatives, vegan margarine, vegan cheese, vegan ready meals/food-to-go and seafood alternatives are the highest in Europe. 
Secondly, the emergence of new sources of plant-based protein like aquatic plants will open opportunities for the plant-based protein market. 
Aquatic biomass like microalgae and duckweed is a sustainable alternative source of plant-based protein and bioactive compounds for food and feed applications. For instance, Microalgae, such as Chlorella and Arthrospira spp., and duckweed, can be incorporated in functional food applications, protein supplements, bioactive components, antioxidants, and emulsifiers in food formulations. As a result, rising veganism trends and increasing Attention to Environmental Sustainability in Support of Seaweed Production.

Impact of COVID-19 on the Market
