Turmeric essential oil‐loaded wheat starch cryogels as superabsorbent pads for active packaging of fish fillets

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study aimed to create a cryogel with water‐absorbing and antioxidant properties. Wheat starch (10%, w/v) was used to produce cryogels, which were then incorporated with turmeric essential oil (TEO) at two concentrations: 20% and 30% (w/w of starch).
