Abstract

The consumption of halophytes as healthy gourmet food has increased considerably in the past few years. However, knowledge on the nutritional profile of domesticated halophytes is scarce and little is known on which cultivation conditions can produce plants with the best nutritional and functional properties. In this context, Salicornia ramosissima J. Woods was cultivated in six different salt concentrations, ranging from 35 to 465 mM of NaCl. Both the nutritional profile, the antioxidant capacity, and microbial quality of the produced plants were evaluated including minerals and vitamins. Salt has a marked effect on growth, which decreases for salinities higher than 110 mM. Nonetheless, plants cultivated with intermediate levels of salinity (110 and 200 mM) revealed better antioxidant status with higher amounts of phenolic compounds. Overall, results from this paper indicated that soilless culture systems using low-intermediate salinities produces S. ramosissima plants fit for commercialization and human consumption.

摘要

在过去的几年中，作为健康美食的盐生植物的消费大大增加。然而，关于驯化盐生植物的营养状况的知识却很少，人们也不知道哪种栽培条件可以生产出具有最佳营养和功能特性的植物。在这种情况下，J. Woods 对柳属植物进行了 6 种不同盐浓度（从 35 到 465 mM 的 NaCl）的培养。评估了所产植物的营养状况、抗氧化能力和微生物质量，包括矿物质和维生素。盐分对生长有显著影响，高于 110 mM 的盐度会导致生长下降。然而，在中等盐度（110 和 200 mM）下培养的植物表现出更好的抗氧化状态，酚类化合物含量更高。总的来说，本文的结果表明，使用低-中等盐度的无土栽培系统生产的柳属植物适合商业化和人类食用。
