MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202411009990 A) filed by Council Of Scientific And Industrial Research, New Delhi, on Feb. 12, 2024, for 'an integrated process for the preparation of value-added products from alginate industry residues.'
Inventor(s) include Ravi Singh Baghel; Ashok Shivaji Jagtap; and Manohar Cathrine Sumathi.
The application for the patent was published on Aug. 22, under issue no. 34/2025.
According to the abstract released by the Intellectual Property India: "An Integrated Process for the Preparation of Value-Added Products from Alginate Industry Residues. A substantial amount of residual mass is left over during the industrial processing of alginate seaweeds. The industries that process seaweed face significant difficulties in treating or disposing of such residual mass. The production of a bioactive extract and nanocrystalline cellulose as a value-added product from alginate industry residues was demonstrated in this work using an integrated approach. After processing the residues, 8.37 to 8.67% of bioactive extract were produced, containing 5.1-5.6% of total phenolic content (TPC), around 48-51% of proteins (49% essential amino acid), and 40-42% of fucoidans. The bioactive extract also demonstrated a significant level of antioxidant activity. Additionally, 8.71-9.67% nanocrystalline cellulose was produced, with crystals measuring 2-79 nm in diameter and a 79% crystallinity index (Crl). The study makes the case that waste from the alginate industries could be used as a raw material for manufacturing value-added products for nutraceutical, pharmaceutical and cosmeceutical applications."
