Polyphenols in carobs have recently attracted great attention due to their wide range of biological and health promoting effects. A comprehensive study was conducted to find an optimum method for the extraction, purification and characterization of these valuable bioactive substances. Under this framework, the ultrasound-assisted extraction (UAE) of polyphenols from carob pulp was optimized by the maximization of the yield in total phenolics using response surface methodology. In particular, the effects of solid-solvent ratio, solvent concentration, extraction time, sonication amplitude, and sonication mode were investigated and optimized using a complete experimental design. In comparison to conventional extraction techniques, UAE offered a higher yield of antioxidants and a shorter processing time. Solid-phase extraction was evaluated as a clean-up strategy prior to the electrophoretic analysis of extracts. The results from the analysis of real samples revealed the predominance of gallic acid and highlighted the great influence of the ripening stage on carobs composition.

As a naturally derived biomacromolecule, chitosan is widely utilized in food preservation. However, the chitosan derived from silkworm pupae and its application in food preservation are relatively unexplored. To obtain chitosan with enhanced preservation properties, silkworm pupae chitosan was extracted using dual-frequency ultrasound-assisted chemical and enzymatic methods, followed by a comparative analysis of their physicochemical properties, biological activity, and preservation efficacy on strawberries.

Liver cancer is the fourth most deadly cancer worldwide, but existing treatment options are insufficient, thus highlighting the urgent need for new therapeutic agents. Taxanes, known for their anticancer properties, provide a promising avenue for intervention. In this study, a tetracyclic taxane compound with antitumor activity (taxinine) was extracted and isolated from Taxus chinensis (T.

Background: Monitoring industrial processes is critical for ensuring consistent product quality, as consumers expect uniformity across different production batches. In the case of herbal extracts, such as rosemary hydroalcoholic extracts, it is essential to control the yield of target compounds to maintain both the expected quality and safety. Typically, these extracts are produced in an extractor and then analyzed separately in a laboratory (offline).

Addressing the issues of slow decomposition and low nutrient release efficiency associated with traditional straw returning, this study innovatively applied ultrasound-assisted centrifugal separation technology to prepare submicron/nano-straw particles and systematically conducted a multi-scale investigation from microscopic to macroscopic levels. The core finding reveals that when the particle size reaches the 1 μm threshold, ultrasonic cavitation vigorously disrupts the straw structure, leading to efficient lignin removal (77.45 %) and a significant reduction in cellulose crystallinity, thereby fundamentally enhancing the degradation rate.
