                                             Color Of Fruits And Vegetables Mater

BACK to frequently asked               BACK to Avocado & Glutathione

Color of fruit and vegetables matter:

The green color of leafy vegetables is due to the presence of the green pigment chlorophyll. Chlorophyll is affected by pH and changes to olive green in acid conditions, and bright green in alkaline conditions. Some of the acids are released in steam during cooking, particularly if cooked without a cover.

The yellow/orange colors of fruits and vegetables are due to the presence of carotenoids, which are also affected by normal cooking processes or changes in pH.

The red/blue coloring of some fruits and vegetables (e.g. blackberries and red cabbage) are due to anthocyanins, which means (Any of various water-soluble pigments that impart to flowers and other plant parts colors ranging from violet and blue to most shades of red), which are sensitive to changes in pH. When pH is neutral, the pigments are purple, when acidic, red, and when alkaline, blue. These pigments are very water-soluble.

Vegetable is a culinary term which generally refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat arbitrary and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are normally considered vegetables. Mushrooms, though belonging to the biological kingdom fungi, are also commonly considered vegetables. In general, vegetables are thought of as being savory, and not sweet, although there are many exceptions. Nuts, grains, herbs, spices and culinary fruits (see below) are normally not considered vegetables.

Root vegetables should be stored in a dark, cool, and dry place to prevent mold, greening and sprouting.

During storage leafy vegetables lose moisture and vitamin C degrades rapidly. They should be stored for as short a time as possible in a cool place in a container, such as a plastic bag.

Many root vegetables can be stored through winter in a root cellar. Care should be taken in understanding the properties and vulnerabilities of the particular roots to be stored. Many can last through to early spring and be nearly as nutritious as when fresh.

Vegetable is also used as a literary term for any plant: vegetable matter, vegetable kingdom.  It comes from Latin vegetabilis (animated) and from vegetare (enliven), which is derived from vegetus (active), in reference to the process of a plant growing. This in turn derives from the Proto-Indo-European base weg- or wog-, which is also the source of the English wake, meaning "not sleep". The word vegetable was first recorded in print in English in the 14th century. The meaning of "plant grown for food" was not established until the 18th century.

Since “vegetable” is not a botanical term, there is no contradiction in referring to a plant part as a fruit while also being considered a vegetable (see diagram). Given this general rule of thumb, vegetables can also include leaves (lettuce), stems (asparagus), roots (carrots), flowers (broccoli), bulbs (garlic), seeds (peas and beans) and botanical fruits such as cucumbers, squash, pumpkins, and capsicums. Botanically, fruits are reproductive organs (ripened ovaries containing one or many seeds), while vegetables are vegetative organs which sustain the plant.

The merits of the ongoing question, "is it a fruit, or is it a vegetable?", have even found its way before the bench of the United States Supreme Court which ruled unanimously in Nix v. Hedden, 1883, that a tomato is a vegetable for the purposes of 1883 Tariff Act even though botanically, a tomato is a fruit.

Commercial production of vegetables is a branch of horticulture called olericulture.
