Cricket protein-based film containing Caralluma fimbriata extract-based nanoparticles for preservation of cheddar cheese

Year: 2024

Type: article

Abstract: A bioactive film was developed using cricket ( Acheta domestica ) protein (Cric-Prot) and Caralluma fimbriata extract-based nanoparticles [Car-Fim-NPs (0.0, 1.0, 2.0, and 3.0 % w/v)] to augment the storage stability and functional value of cheddar cheese (Ched-Chee). The Car-Fim-NPs were developed using an ultrasonication-mediated (20 kHz, 500 W, 10 min, pulse duration of 5/5 s on/off) green method. The addition of Car-Fim-NPs modified the film characteristics [density (%), WVTR (mg/mt 2 ), transmittance (%), elongation at break (%), and colour (L*, a*, b*)] and enhanced its antioxidant [DPPH, ABTS and FRAP activities, total phenolic and flavonoid contents, and antioxidant release (%)] and antimicrobial (inhibitory halos against E. coli and S. aureus ) potential. Application of the films containing Car-Fim-NPs (1.0–3.0 %) increased the antioxidant potential (DPPH, ABTS and FRAP activities), lipid (TBARS and free fatty acids) and protein (total carbonyl content) oxidative stability, and microbial quality (microbial counts) of the Ched-Chee during 90 days of storage. The sensory quality of Ched-Chee showed a significant increase after day 30 till the storage end. Gastrointestinal digestion simulation augmented the antioxidant potential of Ched-Chee. Overall, the results indicate the possibility of the use of Cric-Prot-based film containing Car-Fim-NPs to enhance the storage quality of Ched-Chee.
