MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202611073823 A) filed by Noida Institute Of Engineering And Technology Niet on June 14, 2026, for Microencapsulated Spermidine Composition Derived From Calocybe Indica Cooking Liquor And Method Thereof.
Inventors include Dr Mansi Mishra; and Dr Richa Mittal.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention discloses a process for recovery, enrichment, and microencapsulation of spermidine from cooking liquor generated during blanching of Calocybe indica (milky white mushroom). The process comprises membrane filtration, low-temperature vacuum concentration, and food-grade enrichment to obtain a spermidine-rich fraction with an enrichment factor of up to 7.5-fold and overall recovery of 72%. The enriched spermidine is encapsulated using a soy protein isolate– dextran and sodium alginate external gelation water-in-oil-in-water double emulsion system, achieving encapsulation efficiencies of 92–99%. Subsequent freeze-drying produces stable microcapsules with water activity below 0.23, a porous network microstructure, and retained encapsulation efficiencies of 56–98%. The invention simultaneously facilitates mushroom de-bittering and valorization of an otherwise discarded processing by-product, converting the cooking liquor into a functional ingredient rich in spermidine. The resulting microcapsules are suitable for incorporation into ready-to-eat foods, packaged cooking-liquor formulations, dietary supplements, and nutraceutical products.
