Summary: The study investigated the effects of storage conditions and cooking methods on the content of chlorophyll, GSL, and sulforaphane in broccoli florets. Results showed that chlorophyll, GSLs, and sulforaphane content decreased with prolonged storage time, with the best preservation performance observed with 1-MCP treatment and 0 degrees C storage condition. Cooking methods also influenced the content of these compounds, with steaming for 7 min or microwaving for 5 min found to be the most effective in preserving the quality and increasing sulforaphane content in broccoli florets.

Summary: Broccoli heads are valuable vegetable crops due to their high nutritional content, but they quickly decompose after harvest. Previous research has shown that foliar application of sodium selenate and selenite can delay this process. This study analyzed the effect of these preharvest treatments on the postharvest shelf-life of broccoli and found that selenium treatments not only delayed yellowing but also maintained the firmness, diameter, and nutritional composition of the heads.

Summary: This study investigated the medicinal potential of Chinese broccoli and found significant variations in the content of sulforaphane, an active anticancer ingredient, among different germplasms. Cluster analysis based on sulforaphane content and qualitative phenotypic traits classified the germplasms into five different groups. These findings not only confirmed the medicinal values of Chinese broccoli but also provided crucial information for future germplasm development and new variety breeding.

Summary: High-pressure processing can increase the isothiocyanate content in broccoli, while improving total phenolic content and enhancing nutritional value. This method also stimulates myrosinase activity, prevents loss of heat-sensitive components, and effectively inhibits oxidases to maintain food quality. Additionally, high pressures have anti-inflammatory and antioxidant effects, making it a potential treatment strategy for healthy foods.

Summary: Blanching conditions were investigated to maximize sulforaphane content in broccoli sprouts. Higher temperatures and shorter immersion times were found to increase sulforaphane content. The optimum conditions were blanching at 61 degrees C for 4.8 min, resulting in a 3.3-fold increase in sulforaphane content compared to untreated sprouts. This process could contribute to the development of functional foods and nutraceuticals containing sulforaphane.

Summary: This study found that soaking and spraying 6-BA can significantly extend the vase life of Curcuma alismatifolia cut flowers, particularly the variety 'Siam Shadow'. Physiological, biochemical, and transcriptomic analyses revealed the involvement of antioxidant enzymes, jasmonic acid, and senescence-associated transcription factors in delaying bract senescence. The findings suggest that 6-BA can act as a potential preservative by affecting gene expression related to JA biosynthesis and signal transduction, antioxidant enzymes, and senescence-associated transcription factors.

Summary: Selenium is an essential trace element for human immune regulation and disease prevention. In plants, organic selenium compounds promote plant growth, improve nutritional quality, and play important roles in plant ecosystems. Selenium accumulation plants release selenium-containing compounds that promote the growth of selenium accumulators but inhibit the growth and distribution of non-selenium accumulators.

Summary: This study investigated the role of dynamic changes in membrane lipid metabolism in GABA-mediated cold tolerance of peach fruits. GABA treatment reduced phosphatidic acid accumulation, attenuated its biosynthesis, and maintained higher levels of phosphatidylcholine and phosphatidylethanolamine, leading to improved cold tolerance. GABA treatment protected peaches against low-temperature stress by maintaining higher levels of specific lipids and enhancing the accumulation of diacylglycerol and triacylglycerol. This study provides novel insights into the mechanisms underlying cold tolerance in postharvest peach fruits.
