Rambutan Seeds, containing oleic acid and arachidic acid

Our habit! Crack rambutan open. Suck in the mouth watering flesh, then threw away the seeds and peels.

Imagine it on industry level, canning. They are simply discarded as waste and treated as of no economic value. What a huge waste of resource! Of course, dumped organic materials eventually decay and become fertilizer. However, we want something more than that. Something we can sell for more profit.

Jirawat Eiamwat et. al. (2014) conducted a study on possible toxicity of rambutan seeds. Why?

Taken from their manuscript:

It is a potential source of edible fat, 4-9% of the whole fruit and 14 to 41% of the seed.

Rambutan seed fat is semi-solid at room temperature (25-27°C) and characterized by high levels of oleic acid between 36.8 and 42.0% and arachidic acid between 34.3 and 36.4% (Harahap et al., 2011; Sirisompong et al., 2011; Solís-Fuentes et al., 2010; Yanty et al., 2013). Due to the physical and chemical characteristics, rambutan seed fat may provide an economic advantage with possible utilization in food and cosmetics.

Take that..

Arachidic acid is for production of detergents, photographic materials and lubricants. Oleic acid is a healthy oil known to lower cholesterol levels. It maybe used as salad dressings, on baking and as replacement of animal fat.

The fear of toxicity fear us from using any unproven commodity, especially if it is not a common food for the man. Rambutan is delicious, perfectly edible and safe but we are unsure about the seeds. The usual practice is outright throw. Another example is the guyabano fruit. The flesh is perfectly safe but the seeds in known to have toxic substances. Thanks to its hard shell. I never affects us on accidental ingestion.

Is rambutan seed toxic?

According to their study results, fat and oils are not lethal to rats at levels of 5,000 mg/kg body weight.

Food technologists and Chemists! Grab the opportunity before somebody else do.

The Three Days Apple Detox Diet

The idea is simple. Eat apples, eat apples and eat nothing but apples for three days. Eat whole apples, never remove the skins. Eat as much as you can toward the center where the seeds lie. Discard the seeds and the little stalk.

Perhaps I should eat these trimmings!

apple trimmings peel and busilThough seeds are claimed toxic – contain cyanide, just like the seeds of guyabano fruit, I have never felt anything unusual after every accidental ingestion.

Why nothing but apples?

Apples are rich in vitamins, minerals and fibers and less in carbohydrates. Those helps in body detoxification – destroying bad substances or binding and taking it out.

It may or may not be a strict apple only diet. Depending on who recommends and or who is the doer, it may be mixed other fruits and vegetables but not meat, fish, dairies and processed foods.

Not sure if the restriction is applicable to irradiated apples. If yes, then we Filipinos cannot do apple detox. Perhaps most apples brought here are irradiated. Please correct me if I am  wrong!

After, it should be followed by a healthy balance diet. Else, it will not be effective. The detox may be repeated as desired but should never be continuous cause our body needs nutrients from variety of foods.

Why apples in three day detox?

Just a wild guess! Apple is chosen because it is very abundant. It is cheap and readily available. Yes, in countries where apple trees grow.

When I was in grade school, our teacher was always telling us to patronize our very own. Buy guava instead of apples. It is also rich in vitamins, minerals, fibers and less in carbohydrates.

Maybe a three days guava diet works too. Three days mango diet or three days rambutan diet.

Note: It is not a guaranteed cure for diseases of any kind.
