Blueberry pomace is a valuable source of a wide range of active compounds and nutrients and is receiving increasing research attention. However, limited attention has been paid in the literature to the nutritional properties and practical applications of blueberry pomace. In this paper, we review the methods used to extract bioactive compounds from blueberry pomace, study their health effects and explore the prospects for their application in the food industry, such as fermented beverages, nutritional supplements or natural colors. In addition, recent studies have examined the content of various active ingredients such as flavonoids, vitamins, and dietary fiber and suggested the validity of the corresponding extraction methods. In addition, these compounds have great potential in human health, such as antioxidant, hypoglycemic, improvement of cognitive impairment and gut health. This analysis also highlights the bioavailability of the active ingredients in blueberry pomace. Thus, blueberry pomace offers a wide field of scientific and technological exploration, but significant challenges must be faced in order to optimize its utilization and promote further research on extraction, applications, and innovative methods.

In this study, a series of novel pyrimidine derivatives incorporating an 1,1,2-trifluoro-1-butene moiety were synthesized and their structures were confirmed by ¹H NMR, ¹³C NMR, and HRMS. The bioassay results demonstrate that 4-methyl-2-[(3,4,4-trifluorobut-3-en-1-yl)thio]-6-(trifluoromethyl)pyrimidine exhibits comparable in vitro antifungal activity against Aspergillus niger (64.55 and 48.85%, respectively) at concentrations of 100 and 50 μg/mL when compared to Prochloraz. Additionally, 4-methyl-2-[(3,4,4-trifluorobut-3-en-1-yl)sulfonyl]-6-(trifluoromethyl)pyrimidine demonstrates superior nematocidal activity against Caenorhabditis elegans at concentrations of 100 and 50 μg/mL after 48 h with corrected mortality rates of 89.65 and 79.47%, respectively, surpassing those observed for ethoprophos. To the best of our knowledge, this study presents the first report on the synthesis and antifungal and nematocidal activities of novel pyrimidine derivatives incorporating an 1,1,2-trifluoro-1-butene moiety.

Capsicum L. is valued for its pungency and nutrition but is susceptible to postharvest deterioration such as weight loss, softening, and decay, leading to reduced quality and marketability. While conventional methods like refrigeration and chemical treatments extend shelf life, they raise safety and environmental concerns. Recently, environmentally friendly preservation techniques have gained attention, including physical (modified atmosphere packaging, cold storage, plasma), chemical (ozone, 1-MCP, chlorine dioxide, nano selenium), and biological (biopolymer films, essential oils, melatonin) approaches. Studies show that combining two or more methods often yields synergistic effects, outperforming individual treatments. This review systematically outlines the physiological and quality changes in postharvest capsicum fruits and summarizes recent advances in key preservation technologies, with emphasis on combined strategies. It aims to provide insights into preservation mechanisms, suggest future research directions, and support the development of safe, effective, and sustainable practices for the capsicum industry.
