Pure natural pickled vegetable curing salt and preparation method thereof

Abstract

The invention discloses pure natural pickled vegetable curing salt and a preparation method thereof. The particle sizes of the pure natural pickled vegetable curing salt are in the range from 2mm to 5mm. The whiteness of the pure natural pickled vegetable curing salt is greater than or equal to 60. The pure natural pickled vegetable curing salt comprises the following chemical components in percentage by weight: 88-94% of sodium chloride, 0.2-0.5% of calcium sulphate, 0.5-1.1% of magnesium sulfate, 1.4-2.2% of magnesium chloride, 0.1-0.2% of potassium chloride, less than 0.05% of water insoluble matters and the balance of water. The preparation method comprises the following steps: (1) preparing mixed brine by mixing new brine and old brine in a volume ratio of (1-4):1; (2) injecting the mixed brine into a beach drying tank of a salt pan, controlling the depth of the mixed brine in the beach drying tank in the range from 2mm to 6mm, carrying out evaporative crystallization under a natural condition, when the particles size of the crystal salt reach 2mm to 5mm, collecting the crystal salt in the beach drying tank, draining and packaging to obtain the pickled vegetable curing salt. The preparation method has the advantages that the raw materials are easy to obtain, the production operating control is simple, the chemical components in the products are purely natural, the cyclic utilization of the brine raw materials is realized, and environment pollution caused by the excessive emission of the old brine is reduced.

Description

technical field [0001] The invention relates to pickle pickling salt and a method for preparing it through natural crystallization under natural conditions. Background technique [0002] Salt for pickling pickles is a subdivision of the edible salt market and is mainly used in the field of pickle pickling. Because pickling salt contains a certain amount of calcium and magnesium ions higher than normal edible salt and moderate particle size, it is widely recognized in the field of pickling pickling. [0003] In recent years, the demand for kimchi pickling salt in the international market, especially South Korea and other countries, has shown a rapid upward trend, while the research on the production of kimchi pickling salt in the domestic market has just started, especially the high-quality natural salt produced under natural conditions. Pickle salt products are almost blank in China. Although the pure natural kimchi pickling salt prepared under natural conditions is also p...

AI Technical Summary

Problems solved by technology

Traditional kimchi pickling salt is generally prepared by mixing edible salt with low-sodium salt and common chemical raw materials. The kimchi pickling salt produced in this way has the risk of contamination of the pickling object due to the addition of chemical raw materials. Health hazards for kimchi eaters

[0004] Domestic research on the preparation method of pickled salt is almost blank, and there are few literature reports
