Cinnamic aldehyde is also known asβ-phenylacrolein and 3-phenyl-2-propionene. It is a pale yellow to yellow liquid, with strong cinnamon aroma. It is naturally found in plant essential oil such as that of Cinnamicon, laurel leaf, hyacinth, rose, Herba Lysimachiae and so on.

Function & Application of Cinnamic aldehyde:

1.It has the function of sterilization, disinfection and anticorrosion. And it has significant inhibitory activity on the fungus.

The Cinnamic aldehyde has inhibitory activity on Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Staphylococcus albus, Salmonella typhi and paratyphoid, Fraenkel’s diplococcus, Bacillus aerogenes, Bacillus proteus, Bacillus anthracis, Salmonella enteritidis, and Bacillus comma, etc. And the sterilization effect on the gram-positive bacterium is effective.
Cinnamic aldehyde can be used to treat many diseases caused by bacterial infection.
In addition, the aldehyde group in the Cinnamic aldehyde can interact with the protein and enzyme in the bacterium to destroy the normal physiological metabolism of the bacteria, and has the effects of inhibiting bacteria or sterilizing.
The Cinnamic aldehyde can inhibit the activity of the fungal shell polysaccharide synthetase, so as to achieve the bacteriostatic effect. When modifying the Cinnamic aldehyde by introducing the ortho-position hydroxyl group, or forming the ortho-hydroxyl group to the benzoic acid ester, the antibacterial activity is obviously improved.

2. It has anti-ulcer effect, and can strengthen the gastrointestinal motility.

3. It has antiviral and antitumor effects.

4. It can enhance the immune function of the body.
Cinnamic aldehyde can degrade into the body’s necessary nutrient components in the intestine after entering the body, and can stimulate the production of lactic acid bacteria, and improve the body fluid immunity and cellular immunity.
The experiments show that the Cinnamic aldehyde can improve the immunity of the body and plays an important role in the prevention and treatment of avian coccidiosis.

Application of Cinnamic aldehyde in animals:

Cinnamic aldehyde can strengthen gastrointestinal motility, promote gastric secretion, as well as enhance digestive function, and then increase animal feed intake.

Cinnamic aldehyde has good anti-mildew and sterilization effect. The feed added with Cinnamic aldehyde can guarantee mold proof, discoloration and odor change.

As a flavor, Cinnamic aldehyde’s own unique odor can improve the animal’s desire to eat. No more flavors and inducers are added to the feed with Cinnamic aldehyde.

Cinnamic aldehyde is recognized as a safe and non-toxic substance (21 CFR 182.60) by U.S. Food and Drug Administration (FDA). American Flavor and Extract Manufacturers’ Association (FEMA) considers it to be a safe and non-toxic food flavor ingredient (FEMA,1965). Joint FAO/WHO Expert Committee on Food Additives (JECFA) also considers Cinnamic aldehyde safe as a food additive (JECFA No. 656).

1.Improve the growth performance.

The Cinnamic aldehyde has the unique antibacterial and bactericidal effect, and can be used for promoting the digestion of the animal’s nutrients in the feed additive. It can improve the palatability of the feed, improve the utilization rate of the feed digestion, promote and improve the growth performance of the animal and the product quality of the animal. In addition, the addition of Cinnamic aldehyde can effectively prevent feed spoilage and prolong the quality preservation time.

Adding Cinnamic aldehyde to feed can stimulate the growth of intestinal beneficial bacteria in male AA broilers. Cinnamic aldehyde reduces the proliferation of harmful bacteria and improves intestinal function, can improve the growth performance of broiler.

2.Antibacterial and antitumor.

Cinnamic aldehyde is warm-natured, spleen protected, and has positive effect on intestinal digestion of piglets. It has a stronger antibacterial activity than that of curcumin.
Many scholars have found that Cinnamic aldehyde has killing, inhibiting and cytotoxicity to a variety of tumor cells in vitro, and can induce apoptosis of tumor cells.

3.Anticorrosion and preservation.

Cinnamic aldehyde has inhibitory effect on different strains, especially Aspergillus flavus.
As a food flavor, Cinnamic aldehyde itself is completely non-toxic and harmless to the human body.
Cinnamic aldehyde has both bacteriostasis and polyphenol oxidase inhibition.

4.Other applications

The researchers found that in the process of aquiculture, the Cinnamic aldehyde can be used in place of the olaquindox, and the comprehensive performance of cinnamic aldehyde is much higher than that of the olaquindox. It is a real green safety additive.
It is found that Cinnamic aldehyde can kill most of the negative bacteria and reduce the production of wastewater because of its broad-spectrum bactericidal effect, which has a positive effect on ecological restoration.
Furthermore, Cinnamic aldehyde can be used as insecticide and mosquito repellent, which has a strong killing effect on Aedes larva that spread yellow fever.
