Abstract

The invention provides vegetable salt. The vegetable salt has a Cu content of 1.98-2.42mg / kg and a Zn content of 70.5-84.3mg / kg. The invention further provides a preparation method of the vegetable salt. The preparation method of the vegetable salt comprises a step of removing heavy metals; and the step of removing heavy metals comprises the following processes: removing the heavy metals by utilizing a chitosan bio-adsorbent, wherein addition amount of the chitosan bio-adsorbent accounts for 0.6% of mass of the extract; controlling temperature of the extract at 36 DEG C and removing the heavy metals for 25 hours. The vegetable salt and the method for preparing the suaeda salsa vegetable salt has the following beneficial effects: the vegetable salt prepared by the method contains no heavy metals, including As, Cd and Cr; and the vegetable salt has a cystine content of 8.2-10.4mg / g, a tryptophan content of 14.2-16.8mg / g, a lactoflavin content of 10.8-13.5mg / kg, a Cu content of 1.98-2.42mg / kg and a Zn content of 70.5-84.3mg / kg.

Description

technical field [0001] The invention belongs to the technical field of plant salt extraction, and in particular relates to a plant salt and a method for preparing Suaeda salsa plant salt by adopting a chitosan biological heavy metal removal process. Background technique [0002] Suaeda salsa (scientific name: Suaeda salsa), known as Suaeda salsa in Northeast China, Suaeda salsa in Hebei, and Suaeda salsa in Inner Mongolia, is a plant of the genus Suaeda salsa in Chenopodiaceae. It is an annual herb, usually growing on the saline-alkali wasteland in the seashore and desert, and is a typical indicator plant of saline-alkali land. Suaeda salsa is the dominant species on the silt beach of the plain coast of more than 1,000 kilometers from the Xiuzhen River estuary at the junction of Sulu to the Yangtze River estuary along the Jiangsu coast. Distributed in Hebei, Qinghai, Shanxi, Zhejiang, Northeast China, Ningxia, Inner Mongolia, Shaanxi, Xinjiang, Jiangsu, Shandong, Gansu and ...
