MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202611073827 A) filed by Noida Institute Of Engineering And Technology Niet on June 14, 2026, for Method For Extending Shelf Life Of Crude Jackfruit Seed Oil Through Integrated Oxidative Stabilization.
Inventors include Dr. Asad Amir; and Dr. Dolly Sharma.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention discloses a method for enhancing oxidative stability and extending the shelf life of crude jackfruit (Artocarpus heterophyllus Lam.) seed oil. The method comprises minimal-refining cold-press extraction to preserve endogenous tocopherols and natural antioxidants, synergistic stabilization using a ternary blend of rosemary extract, ascorbyl palmitate, and lecithin, nitrogen-flushed modified atmosphere packaging in opaque containers with one-way valve closures, and non-invasive oxidation monitoring through ATR-FTIR and UV-Vis spectroscopic parameters. The crude oil retains approximately 1000 mg/kg total tocopherols, substantially higher than refined oil, providing effective chain-breaking antioxidant protection. Under accelerated oxidation conditions at 60°C for 45 days, the stabilized oil exhibits significantly reduced deterioration, reflected by lower acid value, peroxide value, p-anisidine value, and TOTOX indices. The integrated preservation system achieves a projected shelf life of 18–24 months at 25°C and 30–36 months at 4°C, enabling valorization of jackfruit seeds into a commercially viable antioxidant-rich edible oil.
