Does colour depth matter
The depth of colour in fruits usually correlates immediately with their phytochemical content material. A deeply coloured blueberry usually accommodates extra anthocyanins than a lighter coloured one. A deep crimson strawberry typically has extra anthocyanins than {a partially} whitened one.
This color-intensity precept explains why wild berries, which regularly develop underneath extra aggravating circumstances, usually have deeper colours and better antioxidant ranges than their commercially grown counterparts. The difficult rising circumstances immediate the vegetation to supply extra protecting compounds, leading to extra intense colours and doubtlessly higher well being advantages.
Rising circumstances considerably affect a fruit’s colour growth and phytochemical content material. Fruits grown with optimum solar publicity develop extra vibrant colours and better ranges of helpful compounds. Equally, fruits allowed to ripen totally on the plant fairly than being picked early and ripened throughout transport usually develop extra full colour and dietary profiles.
Seasonal differences additionally have an effect on colour growth. Blueberries grown during times of temperature fluctuation usually develop deeper colours and better antioxidant ranges than these grown in constant temperatures.

Berries cooked right into a pie could lose a few of their water-soluble anthocyanins however retain different helpful compounds.
Freezing typically preserves most color-related compounds if achieved correctly. The fast freezing utilized in business processing helps preserve mobile integrity, locking in most of the helpful pigments.
