Product Introduction

Zinc citrate, a zinc salt derived from citric acid, is frequently utilized as a source of zinc in dietary supplements and food fortification. Its popularity stems from its favorable bioavailability and mild taste compared to other zinc salts, such as zinc sulfate. Zinc is an essential trace element vital for numerous physiological functions, including immune function, wound healing, protein synthesis, and DNA synthesis [1]. As a result, zinc citrate serves as an effective means to address zinc deficiency and support overall health.

Production Process

The production of zinc citrate generally involves reacting citric acid with a zinc source, such as zinc oxide or zinc carbonate, in an aqueous solution. The reaction is carefully controlled to ensure the formation of zinc citrate with the desired purity and particle size. The resulting zinc citrate is then purified, filtered, and dried to obtain a stable and readily usable product [2]. The specific parameters of the reaction, such as temperature, pH, and reactant ratios, can be adjusted to optimize the yield and quality of the final product.

Product Functions and Effects

Zinc citrate, as a source of zinc, plays a crucial role in supporting various bodily functions. Zinc is an essential mineral required for the activity of numerous enzymes involved in metabolism, growth, and development [3]. It is also critical for maintaining a healthy immune system, protecting the body against oxidative stress, and supporting cognitive function. Adequate zinc intake through zinc citrate supplementation can help prevent zinc deficiency, which is associated with impaired immune function, delayed wound healing, and increased susceptibility to infections [4].

Product Application Scenarios

Zinc citrate finds widespread application in the food and dietary supplement industries. It is commonly used to fortify food products, such as cereals, infant formulas, and beverages, to increase their zinc content [5]. In dietary supplements, zinc citrate is available in various forms, including tablets, capsules, and powders, and is often included in multivitamin and mineral formulations. Its relatively neutral taste and good bioavailability make it a preferred choice for zinc supplementation, particularly for individuals who may be sensitive to the taste or gastrointestinal effects of other zinc salts.

Packaging and Storage

Zinc citrate is typically packaged in airtight containers to protect it from moisture and contamination. It should be stored in a cool, dry place, away from direct sunlight and extreme temperatures, to maintain its stability and quality [6]. When stored properly, zinc citrate has a shelf life of approximately 24 months. It is important to follow the manufacturer's recommendations.
