Have you noticed that there are very few products made of rambutan. Try searching super malls, groceries, supermarket and the like. if your not lucky, finding products made of rambutan is going to be a hard task.
In fact, this delicious fruit can be manufactured into variety of products. Products may include jam, juice, preserves, marmalade, jellies and as flavoring to other food commodities. So what makes rambutan not suitable for food processing?
When I was still a Student Worker in my alma mater, our boarding house was inside the fruit plantation and animal project area. An approximate of ten rambutan trees can be found around the boarding house. I have three buddies living with me there. Every fruiting season, we secretly eat ripe rambutan fruits. I can eat one to two kilograms of it and still craving for more. This fruit is so delicious, clients keep on coming to ask for a fresh pick. The fruits are readily exhausted in just two weeks from the time of ripening.
My mother has one rambutan tree in her front yard. During fruiting season, I can barely see a red ripe rambutan because they are getting the fruit in their rare-ripe stage, manibalang.
Rambutan is expensive but very salable fruit. We barely experience a surplus of supply. Why bother processing it to jam, juice and other products if it can be sold easily at for a high price.
