This work is aimed to assess the effect of ultrasonic pre-treatment on the enzymatic hydrolysis of zein and the nanoencapsulation of vitamin D (VitD) by zein hydrolysates (ZH). The ultrasonic pre-treatment significantly increased the degree of hydrolysis by and the α-helix, β-sheet, β-turns contents, and random coils were enhanced by ultrasonic pre-treatment. VitD was successfully encapsulated by the developed ZH nanoparticles (NPs), with an encapsulation efficiency of 95.23 ± 1.78 %. The surface charge and particle size of the nanoparticles (NPs) were -5.45 ± 1.76 mV and 39.43 ± 7.96 nm, respectively. The detailed morphology study of NPs showed a regular spherical morphology, and the chemical structures of NPs were characterized by Fourier Transform Infrared Red spectroscopy. Additionally, the developed NPs were added to milk, which exhibited high stability after one month of storage. In conclusion, the VitD-loaded ZHNPs had considerable potential for fortifying different foodstuffs.

Egg white protein's functional properties and digestibility can be significantly affected by processing methods. In this study, a novel combined ultrasound-heating (UH) pretreatment protocol was developed, where liquid egg white was subjected to ultrasonic treatment (0.4 W/mL, 10 min) followed by mild heating (72 °C, 10 min) prior to drying processes.

Aquafaba is the liquid that remains from the cooking of beans in the canning industry, generally discarded as wastewater. This research aimed to optimize ultrasound pretreatment to enhance this by-product and introduce it as a high-added value product (known as liquid gold) in the food industry. The results showed that with the increase in the sonication time and amplitude, the extraction efficiency, soluble protein content, the density, and dry matter content of black chickpeas aquafaba increased significantly (p < 0.

Article Synopsis
- The study aims to develop and validate machine learning techniques to predict how patients with advanced hepatocellular carcinoma respond to a treatment combining a tyrosine kinase inhibitor and an anti-PD-1 antibody.
- Researchers analyzed clinical data and ultrasound images from 134 patients to extract relevant features that indicate tumor characteristics and microenvironment changes.
- Three predictive models were built using the extreme gradient boosting algorithm, and their effectiveness was measured using various performance metrics to enhance treatment decision-making for patients.
