“…Similarly, for agar, the demand is 400 tonnes year −1 , and barely 150 tonnes year −1 is being produced in the country [10]. The scenario for alginate is also similar-the demand is about 1000-2000 tonnes year −1 , and barely 250-300 tonnes year −1 is being produced [11]. Thus, seaweed hydrocolloids are being imported for domestic needs.…”

“…The Agar and Alginate Manufacturers Welfare Association, Madurai, Tamil Nadu-the largest conglomeration of small-scale seaweed-based industries in India-welcomed the announcement of the seaweed park, and consider that it would boost the industry (Mr. A Bose Ramachandran, President of the Agar and Alginate Manufacturers Welfare Association, personal communication). It should be noted that several of these industries are on the brink of closure due to impediments, such as the dearth of feedstock from natural harvest, and the low technological and technical methodologies that are still being practiced for the manufacturing of agar and alginate by these industries [10,11]. The expectations of stakeholders through this initiative are as follows: (a) implementation of large-scale farming of seaweed-not only of Kappaphycus alvarezii, but also of other native seaweeds, which have shown considerable promise, namely, G. edulis [19], G. debilis [20], G. dura [21,22], and Ge.…”

The Food and Agriculture Organization (FAO) of the United Nations ranks India at 13th position with 5300 wet tones of seaweed harvest (0.2% of global production). The domestic micro or medium enterprises still overwhelmingly rely on wild harvest for feedstock. The production of hydrocolloids and bio stimulants for agriculture has been the main product portfolio for the last several decades. Nevertheless, with 7516.6 km of coastline, this sector holds enormous promise for sustainable economic development. The strong “Innovation Quotient” proved to be the crucial driving force to develop several novel products backed up with intellectual property rights. Appreciable steps have been taken by the Union Government of India to give further fillip to the marine sector through different forums to achieve a sustainable and circular Blue Economy. The purpose of this thematic article is to collate the state-of-the-art information on the cultivation and processing sector in the country, and to provide recommendations for evidence-based sector management and policy decision making. The proposal of establishing a “Multipurpose Seaweed Park”—the first of its kind in the world—in Tamil Nadu is a very pertinent first step towards the cause of modernizing and improving the domestic industries, adopting improved processing and sustainable and green technologies. The analysis revealed that in order to fulfill these objectives, more coordinated efforts of several stakeholders are necessary, along with the cooperation of different government departments and industry participation. The lessons learned would help in furthering our collaboration with countries of the Indian Ocean region and the South Asian Association for Regional Cooperation, for mutual benefit.

“…The extraction of alginates from these seaweed species highlights their significance as abundant and renewable resources for producing versatile biopolymers. These alginates play a vital role in a myriad of industrial applications owing to their unique properties and eco-friendly nature [2]. Alginate, a linear polysaccharide, is composed of covalently bonded D-mannuronate (M) and its epimer, L-guluronate (G), arranged in various sequences.…”

Three ionic liquids (ILs) and three deep eutectic solvents (DESs) with identical counterparts, as well as their aqueous solutions, were prepared for the selective extraction of alginate from Sargassum tenerrimum, a brown seaweed. It was found that the ILs and their hydrated systems were only able to extract alginate from the seaweed directly, while the DESs were not, as confirmed by molecular docking studies. When the quality of the polysaccharide was compared to that produced using the hydrated IL system with the widely used conventional method, it was discovered that the physicochemical and rheological characteristics of the alginate produced using the ILs as solvents were on par with those produced using the conventional method. The ILs can be seen as acceptable alternative solvents for the simple extraction of the polysaccharide straight from the seaweed given the consistency of the extraction procedure used in conventional extraction processes. The hydrated ILs were discovered to be more effective than their non-hydrated counterparts. The yield was also maximized up to 54%, which is much more than that obtained using a traditional approach. Moreover, the ionic liquids can also be recovered and reused for the extraction process. Additionally, any residual material remaining after the extraction process was converted into cellulose, making the process environmentally friendly and sustainable.

“…Along India’s long coastline of about 7500 km, the natural seaweed collection has been the source of livelihood for coastal fisherwomen for several decades, especially in Gujarat and Tamil Nadu. Seaweed-based processing industries utilize this feedstock for the production of hydrocolloids, mainly agar, alginate and to a lesser extent carrageenan [ 12 , 13 , 14 ]. The use of seaweed for food has been considered as an area of research by CSIR—Central Salt and Marine Chemicals Research Institute, Bhavnagar.…”

Seaweeds are inevitable resources of nutrition bearing favorable rheological characteristics, which has resulted in their inclusion in a variety of daily consumer products. India, with its vast coastline and over 1000 species of seaweeds, presents tremendous potential to bring this resource into nutraceuticals and the food sector. The present survey was designed for the Indian population, which was further classified according to diet preferences, age groups, gender and various occupations. Their perceptions regarding nutritional aspects, sensory views, safety hazards and resource reliability were recorded. Among all groups studied, gender represented significant differences upon the various safety opinions recorded (p < 0.001) compared to the occupations, age groups and diet preferences studied. In addition, the dataset revealed the pro-phycological behavior of consumers subjected to vital concerns about bioresource reliability and pre-processing to avoid health hazards related to wild harvest or on-shore cultivated samples. In addition, consumer responses also revealed potential inhibitory factors in edible applications such as taste and smell. This study suggests that collaborative efforts among media, culinary experts and phycologists could play a pivotal role in promoting seaweeds in the rapidly expanding food sector industry of India.
