Vanilla is a flavor derived from orchids of the genus Vanilla, primarily from the Mexican species, flat-leaved Vanilla (Vanilla Planifolia). The word Vanilla, derived from the diminutive of the Spanish word Vaina (Vaina itself meaning Sheath or Pod), simply translates as little pod.
The majority of the world's Vanilla is the Vanilla Planifolia species, more commonly known as Bourbonvanilla (after the former name of Réunion, Île Bourbon) or Madagascar Vanilla, which is produced in Madagascar and neighboring islands in the southwestern Indian Ocean, and in Indonesia.
as a vine, climbing up an existing tree (also called a tutor), pole, or
other support. The distinctive flavour compounds are found in the
fruit, which results from the pollination of the flower. One flower
produces one fruit. Vanilla Planifolia flowers are hermaphroditic: They carry both male (anther) and female (stigma) organs.
Stages of production :
The Vanilla fruit grows quickly on the vine, but is not ready for harvest until maturity - approximately six months. Harvesting Vanilla
fruits is as labor-intensive as pollinating the blossoms. Immature dark
green pods are not harvested. Pale yellow discoloration that commences
at the distal end of the fruits is an indication of the maturity of
pods. Each fruit ripens at its own time, requiring a daily harvest. To
ensure the finest flavor from every fruit, each individual pod must be
picked by hand just as it begins to split on the end.
Sweating is a hydrolytic and oxidative
process. Traditionally, it consists of keeping fruits, for seven to 10
days, densely stacked and insulated in wool or other cloth. This retains
a temperature of 45 - 65 °C and high humidity. Daily exposure to the sun
may also be used, or dipping the fruits in hot water. The fruits are
brown and have attained much of the characteristic Vanilla flavor.
of the beans to 25 - 30% moisture by weight, to prevent rotting and to
lock the aroma in the pods, is always achieved by some exposure of the
beans to air, and usually (and traditionally) intermittent shade and
Conditioning is performed by storing the pods for five
to six months in closed boxes, where the fragrance develops. The
processed fruits are sorted, graded, bundled, and wrapped in paraffin
paper and preserved for the development of desired bean qualities,
especially flavor and aroma. The cured Vanilla fruits contain an average of 2.5% Vanillin.
the fruit is more than 15 cm in length, it belongs to first-quality
product. The largest fruits greater than 16 cm and up to as much as 21
cm are usually reserved for the gourmet Vanilla market, for sale
to top chefs and restaurants. If the fruits are between 10 and 15 cm
long, pods are under the second-quality category, and fruits less than
10 cm in length are under the third-quality category. Vanilla is the second most expensive spice after Saffron, because growing the Vanilla seed pods is labor-intensive.
There are many compounds present in the extracts of Vanilla. The chemical compound Vanillin is primarily responsible for the characteristic flavor and smell of Vanilla. Another minor component of Vanilla essential oil is piperonal (heliotropin). Piperonal and other substances affect the odor of natural Vanilla.
