Potassium Iodate

Potassium Iodate is an ionic inorganic compound with CAS Number 7758-05-6. It appears as a white crystalline powder that is odorless and highly soluble in water.

Unlike potassium iodide, Potassium Iodate is more stable in the presence of moisture, heat, and impurities, making it the preferred form for long-term iodine supplementation in salt and other products.

Potassium Iodate, a stable inorganic salt widely used as a reliable source of iodine in food fortification, a dough strengthener in baking, and an oxidizing agent in analytical chemistry and manufacturing.

Technical Specifications

Package & Storage

• 25kg/30kg drum (packaged in polyethylene bags, and the outer packaging is a full-paper drum).

• Store in a cool, well-ventilated warehouse. Keep away from sources of ignition and heat. Avoid exposure to light. Ensure the packaging is sealed.

Benefits of Potassium Iodate

Stable Iodine Source:

Provides bioavailable iodine with superior resistance to degradation compared to iodide forms, ideal for humid or high-temperature storage conditions.

Dough Conditioning:

Strengthens gluten in bread dough, improving volume, texture, and processing tolerance in commercial baking. 

Oxidizing Power:

Serves as an effective oxidant in analytical titrations (iodometry) and chemical synthesis.

Nutritional Fortification:

Helps prevent iodine deficiency disorders when used in table salt or other foods.

Applications and Uses of Potassium Iodate

Potassium Iodate is approved for specific uses under FDA regulations (21 CFR 184.1635) and finds applications in the following areas:

Food Industry

• Flour Treatment and Baking: Used as a dough strengthener and oxidizing agent in bread production.

• Salt Iodization: Preferred iodine source for fortifying table salt and select food categories due to its stability.

• Nutrient Supplement: Functions as a source of dietary iodine to support thyroid health.

Pharmaceutical and Medical Uses

• Ingredient in certain thyroid medications and iodine supplements.

• Used in some baby formulas and nutritional products to support thyroid function and prevent deficiency.

Laboratory and Industrial Applications

• Analytical Chemistry: Primary standard in iodometric titrations for determining reducing agents.

• Oxidizing Agent: Used in organic synthesis and oxidation reactions.

• Other: Feed additives, textile processing, and specialized chemical manufacturing.

Frequently Asked Questions (FAQs)

Q: Is Potassium Iodate approved for food use?

A: Yes, it is affirmed for use as a dough strengthener in bread and as a nutrient supplement in iodized salt and other applications.

Q: Why is Potassium Iodate preferred over Potassium Iodide for salt iodization?

A: Potassium Iodate is more stable in the presence of moisture, impurities, and during long-term storage or distribution, especially in warm or humid climates.

Q: What is the primary function of Potassium Iodate in baking?

A: It acts as an oxidizing agent and dough conditioner, strengthening gluten networks to improve dough elasticity, gas retention, and final bread volume.

Q: Is Potassium Iodate safe for human consumption?

A: When used within regulated limits in food, it is considered safe as a source of essential iodine.  However, pure Potassium Iodate is an oxidizer and should be handled with care;  excessive intake of iodine can have health effects.

Q: How should Potassium Iodate be stored?

A: Store in a cool, dry, well-ventilated area in tightly sealed containers, away from combustible materials, reducing agents, and sources of heat.

Q: Can Potassium Iodate be used in analytical chemistry?

A: Yes, it is commonly used as a primary standard in redox titrations (iodometry) due to its high purity and stability.
