Potassium Cinnamate Key Features

Natural and effective preservative

Potassium cinnamate has a strong inhibitory effect on a variety of spoilage microorganisms, including mold and bacteria. Its preservative effectiveness is over three times that of sodium benzoate, while maintaining the original flavor and texture of the food.

Safe and non-toxic

As a natural potassium salt of cinnamic acid, this product is absorbed by the body and metabolized into phenylalanine. It is safe and leaves no residue. It also supplements the trace element potassium, which has certain health benefits for Peking Opera.

Strong stability

Potassium cinnamate maintains excellent antibacterial properties in both acidic and neutral conditions, making it suitable for processing various beverages, dairy products, and meat products.

Versatile

In addition to its excellent antiseptic properties, it also possesses antioxidant, anti-inflammatory, and UV protection properties, making it useful in cosmetic formulations and other fields.

Potassium Cinnamate Main Applications

Spices and fragrance ingredients

Potassium cinnamate has a natural cinnamon aroma and can be used as a flavoring and fixative to enhance the longevity of the main fragrance. It is suitable for beverages, candies, cosmetic fragrances, and soaps.

Cosmetics and skincare

As a natural antibacterial and UV-blocking ingredient, it is an essential ingredient in sunscreens and brightening skincare products, helping to reduce dark spots and improve skin barrier function.

Improving meat product quality

Adding an appropriate amount of C9H7KO2 to meat products such as fresh meat and dried meat can prevent bacterial growth and slow oxidation. It can also reduce the use of nitrites and improve color and taste.

Preservative applications

Potassium cinnamate is commonly used in the preservation of beverages, fruits, dairy products, and meat products. A 0.1-0.5% addition effectively inhibits spoilage bacteria, extends shelf life, and preserves the original flavor of food.

Precautions

  1. Since potassium cinnamate may decompose to produce cinnamic acid when exposed to strong acids, it should be used in a neutral or slightly alkaline environment and avoid contact with strong acids or strong oxidants.

  2. It is best to store under an inert atmosphere to avoid moisture absorption or reaction with certain components in the air.

  3. Wear gloves and protective glasses when handling to avoid direct contact with skin and eyes. If contact occurs, rinse with plenty of water.

  4. Waste potassium cinnamate must not be discharged into the sewer or the natural environment at will, and should be sorted and disposed of in accordance with local regulations.

FAQ

1. What are the advantages of potassium cinnamate over sodium benzoate?

Derived from natural cinnamic acid, potassium cinnamate is safer (non-toxic) than sodium benzoate, has stronger antibacterial properties, and can be converted into nutrients in the body. Sodium benzoate, on the other hand, is chemically synthesized and poses potential health risks, resulting in restrictions in many countries.


2. What is the recommended dosage of potassium cinnamate?

It's generally between 0.1% and 0.5%, with slight variations depending on the food type and pH environment. Please comply with each country's food safety standards and application guidelines.
