每周定期饮食摄入西兰花与改善健康有关，但西兰花副产品（农作物残留物）的工业用途可以忽略不计。在西班牙（欧盟主要西兰花生产国之一）等国家，增加西兰花副产品的价值具有科学和经济利益。本文重点介绍采用 80 mM NaCl 处理的温室栽培西兰花产品（收获残留物）的生物活性化合物（芥子油苷、酚酸和类黄酮）和营养素（维生素 C、矿物质和微量元素）以及体外自由基清除能力 (DPPH.test)，代表穆尔西亚（西班牙东南部）生产区目前可用的灌溉水。在马拉松、努比亚和堇菜品种中，生物活性化合物和营养成分根据品种、器官（叶或茎）和盐胁迫（80 mM NaCl）而变化。 Nubia 品种没有受到 80 mM NaCl 的显着影响，Nubia 副产品中的植物化学物质和营养成分的含量落在可食用商业部分（花序或花头）的健康促进水平范围内。因此，通过获得生物活性成分和营养物质来增加西兰花农作物的价值，可以使食品和药品行业受益。 实际应用：农业食品工业的许多副产品可用作营养物质和潜在功能成分的来源，从而有机会获得附加值产品。之前的研究主要集中在可食用小花上，但在本例中，我们感兴趣的是西兰花副产品的增值，这在生产现场是一个真正的问题，因为尚未设想这种材料的预期用途。因此，本研究的目的是增加西兰花衍生副产品的价值，因为回收所有这些农业废弃物以获得工业用生物活性成分可以提高利润并降低成本和环境问题。
The regular dietary intake of broccoli on a weekly basis has been related to better health, but industrial use of broccoli by-products ( crop remains) is negligible. Adding value to broccoli by-products in a country such as Spain, one of the main broccoli producers for the EU, is of scientific and economic interest. The present article is focused on the bioactive compounds (glucosinolates, phenolic acids, and flavonoids) and nutrients ( vitamin C, minerals, and trace elements), as well as the in vitro radical-scavenging capacity (DPPH.test), of the broccoli products ( harvest remains) resulting from greenhouse cultivation using 80 mM NaCl treatment, representative of the currently available irrigation water in the production areas of Murcia ( SE Spain). The bioactive compounds and nutrient contents varied according to the cultivar, organ ( leaves or stalks), and the saline stress ( 80 mM NaCl), in the cultivars Marathon, Nubia, and Viola. Cultivar Nubia was not affected dramatically by 80 mM NaCl and the contents of phytochemicals and nutrients in the by-products of Nubia fell within the range of health-promoting levels of edible commercial parts ( inflorescences or flower heads). Therefore, adding value to broccoli agrowaste by obtaining bioactive ingredients and nutrients could benefit the food and drug industry.Practical Application: Many by-products of the agrifood industry may be useful as sources of nutrients and potentially functional ingredients, giving the opportunity to obtain added-value products. Previous studies have been focused on edible florets, but in this case we are interested in adding value to broccoli by-products that represent a real problem in the production sites because no intended use for this material has been envisaged. Therefore, the aim of this study was to add value to the broccoli-derived by-products, since recycling all this agrowaste to obtain bioactive ingredients for industry can boost profits and reduce costs and environmental problems.
