Ascorbic Acid 70% Coated (granular) EINECS 200-066-2 Vitamin C

There is a warehouse in California, USA, and local customers can pick up the goods themselves.

70% Coated (Granular) Ascorbic Acid is a commonly used vitamin C preparation in the industrial, feed, and food reinforcement fields.
Simply put, it is a "concentrated, moisture-proof, and sustained-release" vitamin C additive.
70% Content:
This means that in this product, real ascorbic acid only accounts for 70% of the total weight.
The remaining about 30% is usually the carrier (such as starch, maltodextrin), coating material, and anti caking agent to maintain stability.
Comparison: Pure vitamin C powder (with a purity of over 99%) is very delicate and has strong moisture absorption, making it difficult to mix evenly in industrial production. Making it into a 70% formulation is to facilitate weighing and mixing in feed or large-scale food production lines.
Coated/Granular:
Granular: Its physical form is small particles, not fine powder. This makes it have good fluidity, less prone to generating dust, and less likely to fly or layer during mixing.
Coated: The surface of the particles has a special coating. This layer of film is usually made of hydrogenated oil, ethyl cellulose, or other polymers.
This design is mainly aimed at addressing the delicate chemical properties of vitamin C. Pure vitamin C is easily oxidized, thermally decomposed, and prone to moisture absorption and clumping.
Improve stability (heat/pressure resistance):
The coating layer is like putting a "bulletproof vest" on vitamin C. This allows it to withstand high temperatures (usually 60-80 ° C) and high pressure during the feed granulation process, while regular vitamin C quickly loses its effectiveness at high temperatures.
Moisture proof and anti caking:
Prevent moisture from entering the air and ensure that the product remains in a granular state during storage without deliquescence.
Controlled release (slow-release technology):
This coating will only dissolve in specific environments such as gastric acid or intestinal tract. This means that vitamin C is not instantly absorbed in the stomach, but is slowly released, thereby prolonging its action time in the body and improving its bioavailability.
Reduce chemical reactions:
In feed or compound foods, vitamin C is prone to react with trace elements such as iron and copper, leading to its failure. The coating isolates it from direct contact with these metal ions.
Due to its unique physical and chemical properties, 70% coated granular ascorbic acid is mainly used in the following fields, rather than directly as a household medicine:
Animal feed additives (main uses):
Aquaculture: added to fish and shrimp feed to enhance the immune system of aquatic organisms and resist stress reactions caused by transportation and environmental changes.
Poultry/livestock feed: added to pig, chicken and other feed to prevent scurvy (although most livestock can synthesize vitamin C, additional supplementation is needed under stress), promote growth and improve meat quality.
Food fortifiers:
Used as a nutritional enhancer in breakfast cereals, energy bars, meal replacement powders, and other foods that require baking or high-temperature processing.
Fertilizer/Agriculture:
As a plant growth regulator or biostimulant, it is used in high-end water-soluble fertilizers to help crops resist adversity such as drought and cold.
