|Kokum fruits, seeds, pulp and rinds|
Garcinia indica, a plant in the mangosteen family (Clusiaceae), commonly known as kokum, is a fruit-bearing tree that has culinary, pharmaceutical, and industrial uses.
The genus Garcinia, belonging to the family Clusiaceae, includes about 200 species found in the Old World tropics, mostly in Asia and Africa. Garcinia indica is an evergreen, monoecious tree. The tree can grow as high as 18 meters. On maturity the trees attain a pyramid shape. The fruit is an orange size purple color berry with fleshy endocarp. The fruit of the plant contain five to eight large seeds which account for 20-23% of the fruit's weight. The kernels account for 61 percent of the weight of the seed, while the oil content of the kernel accounts for about 44%. The seeds are compressed and embedded in an acidic pulp.
Garcinia indica is indigenous to the Western Ghats region of India located along the western coast of the country. Of the 35 species found in India, 17 are endemic. Of these, seven are endemic to the Western Ghats, six in the Andaman and Nicobar Islands and four in the northeastern region of India. The kokum variety from the Ratnagiri and Sindhudurg districts from the coastal Konkan region of the state of Maharashtra in India has received the GI (Geographical Indication) tag.
Garcinia indica is found in forest lands, riversides and wastelands. These plants prefer evergreen forests, but sometimes they also thrive in areas with relatively low rainfall. It is also cultivated on a small scale. It does not require irrigation, spraying of pesticides or fertilizers.
The outer cover of fruit is dried in the sun to get aamsul or kokam. It is used as a souring agent typically in Maharashtra, Assam, Karnataka, Goa, Gujarat. Kokum yields a peculiar flavour and deep-red colour. As a souring agent, it is used as an alternative to tamarind in curries and other dishes from south India. It is also used in cuisine from Gujarat, where it is frequently used to add flavor and tartness to dal (lentil soup) for flavor balance. It is extensively used in Assamese cuisine in many dishes like masor tenga (sour fish curry) and tenga dali (sour dal).
The fresh fruit is preserved with sugar to make bright-red squash that is diluted with water and bottled for sale as a beverage called Kokum Sarbat.
The extract of the fruit is called aagul in Konkani and Marathi. It is added during the preparation of solkadhi, which may also include coconut milk, coriander and garlic.
The seed of Garcinia indica contains 23–26% Kokum butter, which remains solid at room temperature. It is used in the preparation of chocolate and sugar confectionery.
The oily extract called Kukum butter is used in ointments and suppositories. It has application in skin and hair products, acne products and skin tonics.
The rind of the fruit is a good source of hydroxycitric acid which has been claimed to modify lipid metabolism.
The tree is ornamental, with a dense canopy of green leaves and red-tinged, tender, young leaves.
