Additionally, the films showed good biocompatibility, biodegradability, and a sensitive color response to ammonia.

The results showed that ultrasonication caused uniform hydrophilic BSA and MA particle formation in optimal conditions.

This contrasts with the dilute exponents (<em>a</em> ∼2) typically observed in polymer–solvent systems.

Pre-soaked whole buckwheat (BW) grains were subjected to HHP treatment under different processing conditions: two pressure levels (300–600 MPa) and three holding times (0-5-15 min) to evaluate the techno-functional and nutritional response of the resulting flours. Significant (p < 0.05) increases in water absorption capacity and swelling capacity were observed in the flours resulting from longer treatment times (5–15 min) and the highest-pressure level (600 MPa).
