Article Abstract

Optimization of seven parameters of stir bar sorptive extraction (SBSE) on mulberry volatile components for the first time. A total of 347 volatile components were identified and quantified in 14 mulberry varieties, predominantly encompassing esters, aldehydes, terpenoids, hydrocarbons, ketones, alcohols, heterocyclics, acids, and phenols. Hexanal and (E)-2-hexenal were the dominant volatiles. Furthermore, 79 volatile compounds characterized by odor activity values (OAVs) > 1 were identified, making a significant contribution to the distinctive mulberry flavor. "Green" notes were the most intense, followed by "fatty" and "fruity". Utilizing odor ring charts, the volatile flavor characteristics of the 14 mulberry varieties could be intuitively distinguished. This study not only established a viable methodology for differentiating mulberry varieties but also laid a theoretical foundation for the quality evaluation and variety breeding of mulberry flavor.

The interest in synthesizing new dielectric materials is caused by their potential application in various electronic and sensor devices as well as in a large variety of electronic components. The present work reports the synthesis of glasses in the NaO/AlO/BaO/ZrO/TiO/BO/SiO system prepared by melt-quenching. These glasses were then crystallized to glass-ceramics by a controlled thermal treatment.

Mulberries, despite its rich nutritional and health-promoting properties, are commonly associated with high post-harvest waste. Fermenting them into mulberry wine can increase their added value. This study investigated changes in mulberry physicochemical properties, antioxidant capacity, volatile, and non-volatile compounds pre- and post- fermentation using two varieties (Seedless Dashi and Taiwanese long-fruited mulberries).

The mulberry tree, a Morus genus plant from the Moraceae family, is rich in polysaccharides. An increasing number of studies have indicated that Morus polysaccharides possess a variety of biological activities. In this review, we provide a detailed summary on the recent research advances in the extraction, purification, structural properties, and biological activity of Morus polysaccharides over the past decade, with a focus on comparing the monosaccharide composition and activity differences between polysaccharides from different mulberry species.
