Product Description
Referred to colloquially as "white small salt," this substance primarily denotes white granular raw salt manufactured through solar evaporation techniques. Characterized by its fine, homogenous crystalline particles and bright white hue, it originates from seawater or salt-lake brine that undergoes natural evaporation facilitated by sunlight and wind. In contrast to refined salts, it undergoes minimal processing, thereby retaining natural mineral constituents like calcium, magnesium, sulfates, and trace elements. With a sodium chloride (NaCl) concentration spanning 85% to 95%, it harbors greater impurities than refined salts, endowing it with unique physical and chemical attributes tailored for specific industrial and agricultural purposes.pH Characteristics With a pH range of 7 to 8, the salt displays neutral to alkaline properties, primarily due to the hydrolysis of magnesium salts. This attribute provides a mild buffering capacity, which is advantageous in water treatment processes.
Production Process and Characteristics
The fabrication of Xiaobai salt is fundamentally dependent on solar evaporation, an age-old technique in which brine is directed into shallow basins or ponds. As sunlight heats the water, evaporation takes place, progressively concentrating the salt until crystals develop. This natural methodology eliminates the need for energy-intensive refining procedures such as filtration or chemical purification, thereby preserving:
Mineral ImpuritiesCompounds like magnesium chloride (MgCl2), calcium sulfate (CaSO4), and potassium salts are retained, contributing to a slightly grayish or yellowish tinge in certain batches. These impurities are a direct result of the unrefined evaporation process.
Granular MorphologyThe crystals typically exhibit a diameter of 0.5-2 mm, featuring a porous surface structure. This texture enhances solubility and osmotic efficiency, making it particularly suitable for applications such as pickling.

Application
In the fermentation of pickles and preserved vegetables, Xiaobai salt acts as both a preservative and flavor enhancer. It inhibits the growth of spoilage bacteria (e.g., maintaining 3%-5% salt concentration during lactic acid fermentation) while promoting amino acid conversion in vegetables to enhance umami taste. This is evident in traditional recipes like Sichuan pickled vegetables and Korean kimchi, where the salt's granular texture ensures uniform penetration and slow dissolution for balanced flavor development.
For manufacturing cured meats, hams, and sausages, Xiaobai salt employs osmotic pressure to dehydrate meat and suppress microbial activity. It also imparts a savory aroma by interacting with muscle proteins-for instance, Cantonese-style sausages typically use 2%-3% salt by meat weight. The salt's moderate purity (85%-95% NaCl) allows controlled fermentation, as impurities like magnesium salts slightly buffer pH and prevent over-acidification during curing.
In coastal regions, raw salt is utilized to formulate artificial seawater for maintaining seafood viability. For instance, crab live storage requires salinity control at 20-25‰ to replicate natural marine environments, preventing osmotic stress and ensuring physiological stability during temporary rearing.
As a dough improver, it enhances gluten elasticity and fermentation tolerance when added at 0.5-1% ratio, regulating yeast activity and improving texture in baked goods like bread and noodles.
IIn processing high-concentration organic wastewater, raw salt adjusts salinity to create optimal conditions for halophilic microorganisms. For food industry wastewater, maintaining 1-3% salinity significantly boosts anaerobic treatment efficiency by supporting halophile metabolism, accelerating organic matter degradation and production.
As an adjuvant for coagulation sedimentation, strengthen the aggregation of suspended solids through the action of electrolytes (for example, when treating printing and dyeing wastewater, the dosage is about 50 - 100mg/L).
Seawater Desalination Pretreatment
In the reverse osmosis seawater desalination process, raw salt can be used as a pH regulator or scale inhibitor in the pretreatment stage (although the cost is high, it can be obtained locally in some coastal areas).
