phenolic compounds, terpenoid compounds, and alkaloids
.
What are examples of phytochemicals?
A few examples of well-known phytochemicals are the
flavonoids, phenolic acids, isoflavones, curcumin, isothiocyanates, and carotenoids
. The many phytochemicals in common plant foods, herbs, and spices represent a broad range of chemical compounds.
What is Zoochemical?
Zoochemicals are
the animal equivalent of phytochemicals in plants
. They are compounds in animals that are believed to provide health benefits beyond the traditional nutrients that food contains.
What are the three non-nutritive food components?
These include the
beverages coffee and tea

What are bioactive compounds in food?
A type of chemical found in small amounts in plants and certain foods (such as fruits, vegetables, nuts, oils, and whole grains). Bioactive compounds
have actions in the body that may promote good health
. … Examples of bioactive compounds include lycopene, resveratrol, lignan, tannins, and indoles.
How many phytochemicals are there?
Nutrition researchers estimate that
more than 4,000 phytochemicals
have been identified, but only about 150 have been studied in depth. More research is needed to find out which phytochemicals may offer benefits in reducing the risk of cancer.
How do you identify phytochemicals?
Natural compounds can be determined by using
UV-visible spectroscopy
[33]. Phenolic compounds including anthocyanins, tannins, polymer dyes, and phenols form complexes with iron that have been detected by the ultraviolet/visible (UV-Vis) spectroscopy [34].
