Anticancer Properties

The preliminary research suggests that Annatto may have the potential to fight cancer.

For instance, studies in test tubes have shown that extracts of this food coloring could inhibit the growth of cancer cells and cause cells to die in the prostate, liver, pancreas, pancreas, skin cancer cell lines, and other cancer types.

The anticancer potential of Annatto is connected to the compounds that it has, like the carotenoids norbixin and bixin and tocotrienols, which is a form of vitamin E. Although these results are encouraging, further human studies must examine the impacts.

Antioxidant Properties

Antioxidants are compounds that neutralize potentially harmful molecules referred to as free radicals. They could harm your cells if levels are excessively high. Researchers have discovered that damage caused by high levels of free radicals can be linked to chronic illnesses, including cancer, heart diseases, brain disorders along with diabetes.

Antimicrobial Properties 

The research suggests that Annatto could contain antimicrobial qualities. In tests on test tubes, the annatto extracts have been shown to block the growth of various bacteria, including Staphylococcus aureus and Escherichia E. coli. In a separate test-tube experiment, Annatto killed various fungi like Aspergillus Niger Neurospora Sitophila along with Rhizopus Stolonifer. In addition, adding the dye to bread slowed the development of fungi and thus extended bread’s shelf-life.

Similar to this, one study showed pork patties coated with the annatto powder showed less growth of microbes than patties that were not treated after 14 days in the freezer. The research suggests that food colorings could play a role in food preservation.

Promote Eye Health

Annatto is rich in carotenoids that could improve the health of your eyes. Particularly, it’s rich in carotenoids such as bixin and norbixin, both located in the outermost layers of seeds. They also contribute to its vibrant yellow-to-orange color.

In an animal study, norbixin supplement for three months reduced the accumulation of N-retinylidene-N-retinylethanolamine (A2E), a compound which has been linked to age-related macular degeneration (AMD).

AMD is the most common cause of irreversible blindness in seniors. However, humans need to be studied before Annatto is recommended for this purpose.
