Potassium Cinnamate

What is Potassium Cinnamate?

Potassium Cinnamate, also known as potassium phenylacrylate, is the potassium salt of cinnamic acid, a derivative of the natural spice cinnamon series. As the potassium salt form of the food additive "cinnamic acid", it is essentially a highly effective flavor and fragrance. It not only has a special cinnamon aroma, which can improve the flavor of food, but also has a good antibacterial effect, good solubility, and can be completely integrated with food. It is highly favored in the food industry for its unique aroma preservation effect. As a flavoring raw material, it can significantly improve the aroma volatility clarity of the main flavor, making the aroma of the food more intense and lasting.

It is a new natural food preservative worthy of in-depth research and development and vigorous promotion and application. It is widely used in medicine, agriculture and food, and has good development prospects.

Features

Broad-spectrum antibacterial ability: It has a strong inhibitory effect on a variety of microorganisms such as molds, bacteria and yeasts. Its effective concentration for inhibiting mold is 0.05-0.1%, and the commonly used amount is 0.01-0.02%. In addition, potassium cinnamate is not limited by pH and can maintain a good antibacterial effect in a wide range of pH values.

Safety and non-toxicity: It is converted into phenylalanine after being absorbed by the human body and excreted from the body through metabolism, without toxic side effects. Even if it is converted into phenylalanine after ingestion, it can be catalyzed by phenylalanine hydroxylase to generate tyrosine, which is harmless to the human body, and provide the necessary trace element potassium.

Functionality: It is not only an effective preservative ingredient, but also a natural differentiation inducer that has a differentiation effect on a variety of cells, and has health functions such as maintaining excitement and lowering blood pressure.

Excellent solubility and fluidity: It has good solubility and can be converted into cinnamic acid under acidic conditions, thereby playing a preservative role. It has good fluidity and will not be uneven when mixed in food, ensuring the preservative effect.

Strong adaptability to pH: Its antibacterial effect is not affected by the pH of food, and it can maintain good antibacterial effect in food within the pH range of 2-7.

Physiological Functions

Lowering blood sugar and blood lipids: Potassium Cinnamate can help lower blood sugar and blood lipid levels, and has a certain effect on the prevention and treatment of diabetes and its complications.

Antibacterial effect: It has strong antibacterial ability and can inhibit the growth and reproduction of a variety of bacteria, molds and yeasts, especially the microorganisms that cause food spoilage.

Anti-fatigue: It has a certain anti-fatigue effect, can help improve sleep quality, supply sufficient blood to the heart, and achieve the effect of cultivating the body and mind.

Other functions: including anti-inflammatory, vasodilation, etc. It can enhance human immunity, provide the necessary trace element potassium, and avoid the occurrence of hypokalemia.

Product Uses

Food
Preservative: It is a natural food preservative that has a significant inhibitory effect on mold, bacteria and yeast. It is widely used in pastries, candies, beverages, meat products and other foods, effectively extending the shelf life of food.
Flavor Enhancer: It has a natural cinnamon aroma and can be used as a spice to enhance the taste and flavor of food.

Cosmetics
Preservative: In cosmetics, it can be used as a preservative to extend the shelf life of cosmetics and prevent microbial contamination.
Moisturizing and Whitening: It has good skin permeability and moisturizing properties, and can improve the skin's ability to retain moisture; at the same time, it also has the effect of inhibiting tyrosinase activity, which helps to reduce the production of melanin and achieve a whitening effect.

Medicine
It has certain antibacterial, anti-inflammatory and antioxidant effects and can be used to prepare local anesthetics, hemostatic agents and bactericides.

Preparation Method

(1) Weigh 138.8g (1.286mol) silver and 91.18g palladium (0.857mol), dropwise add 400g of 96% nitric acid in excess, raise the temperature to 90°C after the addition is complete, stir for 2 hours, filter, add 265g (22.08mol) of carbon powder to the filtrate, and simultaneously dropwise add 50% KOH solution, stir vigorously until the system pH = 10, continue stirring for 1 hour to allow the carrier carbon powder to be fully adsorbed, filter, and the resulting filter cake is a mixture of silver oxide, palladium hydroxide and carbon powder.

(2) Add 400 mL of 50% KOH pure water solution to the mixture of silver oxide, palladium hydroxide and carbon powder, cool to 20, 24, 27 or 30°C, and add 185 g (2.284 mol) of formaldehyde solution at 20, 23, 26 or -30°C. After the addition is complete, continue the reaction for 0.5 hours, then filter the reaction product, wash it with 1200 g of pure water (wash three times, 400 g each time) until it is neutral, and dry it to obtain 456.5 g of black powdery solid silver/palladium/carbon catalyst.

(3) Dissolve 28g KOH in 700g deionized water to prepare a 4wt% potassium hydroxide solution, then add 7g silver/palladium/carbon catalyst and stir until the material is evenly mixed; heat the material to 60°C, introduce pure oxygen at an oxygen flow rate of 6L/min, and maintain oxygen flow for 15 minutes, then adjust the material temperature to 60°C, add 140g cinnamaldehyde while maintaining the above oxygen flow rate, and add for 5 hours. After the addition is complete, continue to react with oxygen for 10 minutes to obtain a potassium cinnamate aqueous solution;

(4) Filter the potassium cinnamate aqueous solution generated by the reaction, and the resulting filter cake is a silver/palladium/carbon catalyst. Return the catalyst to the reactor for recycling, adjust the pH value of the resulting filtrate to 9.5 with KOH, cool to 12°C, crystallize, centrifuge and dry, and vacuum dry to obtain 182.7g of white flaky crystalline potassium cinnamate finished product with a purity of ≥98.5% and a yield of 92.6% (based on cinnamaldehyde).
