Enhancing malting performance of harder barley varieties through ultrasound treatment
Ultrason Sonochem. 2024 Mar 26;105:106860. doi: 10.1016/j.ultsonch.2024.106860. Online ahead of print.ABSTRACTHarder kernels of barley are regarded as one of the factors that restrict water and enzyme movement within the endosperm during malting. A comprehensive study of two domestic varieties was performed for evaluating malting quality. Both β-glucan and total protein content of the Chinese domestic barley (Ganpi-6 and Kenpi-14) were significantly higher than Copeland. Grain hardness of the Chinese domestic barley was higher and water uptake ratio was lower compared with the Copeland. During germination, the expression ...

Ultrason Sonochem. 2024 Mar 23:106855. doi: 10.1016/j.ultsonch.2024.106855. Online ahead of print.ABSTRACTAssemblies are widely used in biomedicine, batteries, functional coatings, Pickering emulsifiers, hydrogels, and luminescent materials. Polymerization-induced self-assembly (PISA) is a method for efficiently preparing particles, mainly initiated thermally. However, thermally initiated PISA usually requires a significant amount of time and energy. Here, we demonstrate the preparation of nano-assemblies with controllable morphologies and size using ultrasound (20 kHz) assisted ethanol-phase RAFT-PISA in three hours. Usin...
