Variation in Illipe Nut's Fat Yield of Tengkawang-producing Shorea from Several Provenances and Land Races
Illip (tengkawang) nut is a non-wood forest product which has a high economic value and one of export commodities as raw material for illipe nut's fat, cosmetics, and substitution of chocolate fat. Indonesia has 13 species of tengkawang-producing shorea distributed in Kalimantan and some small...

| description | Illip (tengkawang) nut is a non-wood forest product which has a high economic value and one of export commodities as raw material for illipe nut's fat, cosmetics, and substitution of chocolate fat. Indonesia has 13 species of tengkawang-producing shorea distributed in Kalimantan and some small parts of Sumatra. Most of them are categorized as threatened species. To conserve and improve the species for illip nut's fat, it is important to assess the potential of fat yield and physical-chemical properties for each species and provenance. Fruit collection was conducted during fruit season in Kalimantan and Java in 2010. The fruits were collected from four species of tengkawangproducing shorea (i.e. S.macrophylla, S. gysbertsiana, S. stenoptera, S. pinanga) originated from 4 provenances and land races (Gunung BungaWest Kalimantan, Sungai Runtin-West Kalimantan, Bukit Baka-Central Kalimantan, and Haurbentes-West Java). Fruit samples from eleven combinations of species-provenances were extracted to assess fat yield and physical-chemical properties (i.e. moisture content, acid number and free fatty acid). Variation between species-provenances combination was high for all parameters tested, including the illipe nut's fat yield and moisture content. The highest fat yield with lowest moisture content was found in S. stenoptera from Haurbentes (West Java) and S. pinanga from Bukit Baka (Central Kalimantan). Both species-provenance combinations are recommended as genetic material to be developed in the program of ex-situ conservation as well as tree improvement program for the establishment of best seed sources in the same environment condition as the respected provenances. |
