What is Potassium Cinnamate?

Potassium cinnamate is the potassium salt of natural cinnamic acid. It is also a new item newly established in the field of food chemicals. It is non-toxic and also harmless to the human body, risk-free as well as practical, and also has various healthcare functions for the body. And also application leads, its arrival has actually triggered shocks in the food preservation sector. As a natural food chemical, potassium cinnamate has the complying with attributes: solid anti-bacterial capacity, specifically for mold and mildew, germs and yeast that create food spoilage.

Potassium Cinnamate Application

Potassium Cinnamate Uses

  1. Potassium Cinnamate is mainly used for preservative and fresh-keeping of carbonated beverages, fruit juice beverages, canned food, dairy products, pickled vegetable products, etc.
  2. Potassium Cinnamate is mainly used for food preservation, and can also be used as a raw material for flavoring.

Potassium Cinnamate Preparation

Determination of Potassium Cinnamate

The gas chromatography-mass spectrometry analysis method for potassium cinnamate content in food specifically includes the following steps:

(1) Sample extraction: Weigh 2g of the sample and place it in a container, add water to make the volume to 25mL, add acid to adjust the pH of the sample solution to 1, then extract the sample solution with dichloromethane, collect the extracted dichloromethane layer, dry;

(2) Sample derivatization and extraction: Add derivatization reagent to the dried sample in step (1), mix by vortex, react in a water bath for 10 min, cool to room temperature, then add 5 mL of n-hexane for extraction, static After setting, take the supernatant as the test solution;

(3) Determination: The content of potassium cinnamate in the test solution obtained in step (2) was determined by gas chromatography-mass spectrometry; the gas chromatography conditions were: chromatographic column: HP-5msUltraInert30m×0.25mm×0.25μm; Column temperature: 100 °C for 2 min, 15 °C/min to 265 °C for 3 min; inlet temperature 280 °C; injection volume 1 μL; split ratio 1:1; carrier gas helium, column flow: 1.2mL/min; mass spectrometry conditions: EI ion source temperature: 230°C; quadrupole temperature: 150°C; solvent delay 3min; scanning mode: SIM, selected ions are 131, 103, 77, and 67, respectively.

Preferably, the properties of the sample described in step (1) are solid or liquid.

When the sample is solid, the specific steps of sample extraction in step (1) are as follows: Weigh 2g of the solid sample and place it in a 50mL centrifuge tube, add 5mL of deionized water, mix well, ultrasonically extract for 5min, filter, and dilute the filtrate to 25 mL, and then add 2 mol/L sulfuric acid to the filtrate to adjust the pH of the solution to 1, and then extract with dichloromethane three times, collect the dichloromethane layer, and dry it.

When the sample is liquid, the specific steps of sample extraction in step (1) are: weigh 2g of the liquid sample and place it in a 50mL centrifuge tube, add deionized water to make the volume to 25mL, and then add 2mol/L sulfuric acid to the sample solution , adjust the pH of the solution to 1, and then extract three times with dichloromethane, collect the dichloromethane layer, and blow dry.
