pigmentrijke

Pigmentrijke is a Dutch term used to describe substances or materials that have a high content of pigments. In a broad sense it refers to colored compounds that give color and can contribute to functional properties such as nutrition, antioxidant capacity, or visual appeal. The term is commonly applied to foods, plants, cosmetics and paints where pigment concentration influences appearance and quality.

In botany and horticulture, pigmentrijke tissues contain high levels of pigments such as chlorophylls (green, involved in photosynthesis), carotenoids (orange to yellow), and anthocyanins (red to purple). Leaves like spinach and kale are pigmentrijke due to chlorophyll, while many berries and grapes are pigmentrijke because of anthocyanins. Carotenoid-rich vegetables include carrots and sweet potatoes, which contribute orange hues and nutritional value.

In food science, pigmentrijke ingredients contribute color and often health-related properties. The presence of pigments can indicate antioxidant activity and can affect flavor perception. Processing, storage and cooking can alter pigment levels and colors; for example, heating can degrade chlorophyll and certain anthocyanins or shift their hue.

In paints, cosmetics and art materials, pigmentrijke formulations contain a high pigment load to achieve strong color and opacity. Higher pigment content requires appropriate binders and dispersion to ensure stability and workability.

Measurement and terminology: pigment-richness can be quantified by pigment concentration (for example mg per gram) and by color metrics in color spaces. Analytical methods include spectrophotometry and chromatography to quantify chlorophylls, carotenoids and anthocyanins.
