Anthocyanins are colored water-soluble pigments belonging to the phenolic group. The pigments are in glycosylated forms. Anthocyanins responsible for the colors, red, purple, and blue, are in fruits and vegetables.

Carotenoids and Their Isomers: Color Pigments in Fruits and Vegetables

Have you ever noticed how fruits and vegetables have a wide variety of colours? The spectrum goes from orange to purple to green to bright red. Light, and thus colour, is just another type of electromagnetic radiation. All around us electromagnetic waves float around. These can be described by their wavelength and the resulting frequency. Examples of these are waves with very long wavelength such as radio waves or microwaves as well as those with a very short wavelength such as X-rays. That visible spectrum that we can see sits in between these two extremities.

Pigments in Fruits and Vegetables

E-mail: josea. Pigments make nature both colorful and attractive. Humans have always incorporated the natural pigments of fruits, vegetables and spices into their dietary requirements. Naturally occurring red pigments in plants are carotenoids, anthocyanins and betacyanins. Natural pigments, apart from colour, provide added properties and are therefore considered to be bioactive constituents.

Fruits and vegetables are colorful pigment-containing food sources. Carotenoids are some of the most vital colored phytochemicals, occurring as all-trans and cis-isomers, and accounting for the brilliant colors of a variety of fruits and vegetables. View PDF.

This comprehensive treatise provides insight into pigment biosynthesis and dietetics. The text includes current reviews on the genomics of carotenoid, flavonoid, and betalain biosynthesis in plants and the dietetics of these pigments in humans. Pigments biosynthesized in plants are a source of attractive colors in nature and essential nutrients in our daily fruit, vegetable, and grain diet. Deciphered from general perspectives and specific fruits and vegetables, genomics focuses on enzymatic genes and regulatory molecular mechanisms in the biosynthesis pathways to produce these pigments in plants. Dietetics focuses on the nutritional and medical benefits to human health from these pigments as nutrients, nutraceuticals, and disease prevention agents when they are ingested from pigment-abundant plant food and metabolized in human body. His research interests include genomics and bioinformatics, gene cloning and expression profiling, and breeding and selection in citrus. Skip to main content Skip to table of contents.

People who eat more generous amounts of fruits and vegetables as part of a healthy diet are likely to have reduced risk of chronic diseases, including strokes, type 2 diabetes, some types of cancer, and perhaps heart disease and high blood pressure.

The Science of Colours in Fruits and Vegetables

The carotenoid composition of Momordica charantia fruit pericarp at four levels of maturity was extensively investigated. The number of carotenoids isolated increased from five in the immature fruit to six at the mature-green and 14 at the partly-ripe and ripe stages. Cryptoxanthin, which could not be isolated at the immature and mature stages, accumulated rapidly at the onset of ripening to become the principal pigment of the ripe fruit.

March is National Nutrition month, a campaign created annually by the Academy of Nutrition and Dietetics. The campaign focuses attention on the importance of making informed food choices and developing good eating and physical activity habits. According to Dietary Guidelines for Americans, we should eat fruits and vegetables in a rainbow of colors. Different colors add different nutrients and have specific health benefits. These bright colors make fruits and vegetables more desirable, as they brighten your kitchen table. Let us look at why color should play a role when making your next selection.

Biological pigments , also known simply as pigments or biochromes , [1] are substances produced by living organisms that have a color resulting from selective color absorption.
