High Purity Food Grade Zinc Gluconate Powder CAS 4468-02-4 USP/FCC/BP Standard Nutritional Fortifier
FOOD GRADE
ZINC GLUCONATE POWDER
Zinc Gluconate (Food Grade) is a highly refined organic zinc nutritional fortifier with superior bioavailability and excellent sensory profiles. As a white crystalline powder with high water solubility, it provides a stable source of elemental zinc without the metallic aftertaste or astringency common in inorganic zinc salts (e.g., Zinc Sulfate). Meeting the stringent requirements of USP, FCC, and BP pharmacopeias, this organic acid chelate is designed for precision blending in nutritional supplements, infant formulas, and fortified beverages, ensuring consistent mineral delivery and gastrointestinal comfort.

PRODUCT HIGHLIGHTS
High Bioavailability
As an organic acid chelate, Zinc Gluconate is recognized by the body more effectively than inorganic salts. Its high solubility ensures it remains in a bioavailable state throughout the digestive tract for optimal uptake.
Superior Palatability
Specially processed to eliminate the harsh "metallic" taste. This makes it the preferred zinc source for chewable tablets, gummies, and liquid beverages where flavor stability is critical.
Excellent Formula Stability
Exhibits high stability across a wide pH range (pH 3.0 - 7.5). It does not easily react with other food ingredients like proteins or fibers, preventing precipitation or discoloration in complex formulations.
Multi-Standard Compliance
Every batch is strictly tested against USP/FCC/BP standards. Low heavy metal limits (Pb ≤ 2ppm) ensure total safety for sensitive applications such as infant nutrition.
FUNCTIONAL ROLES
1. Immune System Support
Acts as a critical cofactor for over 300 enzymes, supporting cellular immune response and wellness.
2. Protein Synthesis & Growth
Essential for RNA/DNA polymerase activity, promoting healthy growth and tissue repair in children and adults.
3. Cognitive & Sensory Function
Supports healthy neurotransmission and is vital for the maintenance of normal taste and vision.
INDUSTRIAL APPLICATIONS
1. Infant & Toddler Nutrition
Used in premium milk powders and weaning foods as a safe, gentle zinc source.
2. Functional Beverages
Ideal for "Immunity Boost" drinks, energy shots, and fortified water due to its clear solubility.
3. Dietary Supplements
Primary ingredient for zinc gluconate tablets, capsules, and multivitamin premixes.
4. Fortified Cereal & Flour
Applied in large-scale food fortification programs to combat micronutrient deficiencies.
TECHNICAL FAQ
Q1: What are the sensory advantages of Zinc Gluconate over Zinc Sulfate?
A: Inorganic Zinc Sulfate often imparts a strong, bitter, metallic aftertaste and can cause astringency. Zinc Gluconate is significantly more flavor-neutral, allowing formulators to achieve high zinc levels without compromising taste.
Q2: Is Zinc Gluconate stable in acidic functional drinks?
A: Yes. Zinc Gluconate maintains excellent stability and solubility in acidic environments (down to pH 3.0), making it highly suitable for fruit-based energy drinks.
Q3: Does this product meet the heavy metal requirements for infant formula?
A: Absolutely. Our manufacturing process ensures Lead (Pb) levels stay below 2 ppm and Arsenic (As) below 3 ppm, fully complying with the strictest global standards for infant nutrition.
