A Unique and Healthy Mangosteen Concoction

A per suggestion of Dennis, I am going to add one measure of sugar per measure of mangosteen and ferment it for 15 days. It is going to result to a unique and healthy drink.

I got a set of mangosteen peels from my sister. The pulpy seeds should be included in the mix so I am bit puzzled. The pulpy seeds are moisture rich. It helps moisturize the added sugar and turn it to liquid eventually. The moisture within the peels is surely not enough to do the same. My choice are, add some water to  1:1 sugar to peel ratio or follow the recommended but use syrup instead.

A radical change of plan. I saw a 60 °Brix syrup in refrigerator. I used it instead of sugar crystal. I also found some ripe mangoes on table. I added some of it to replace to loss pulpy mangosteen pulp.

Here are the series of non standardized operations in pictures. I need to wait fifteen days to see the outcome.

I felt sorry that I need to terminate this sooner than expected. Curiosity forced me to open the jar. I saw some unwanted mold growth on top. It was my  mistake. I will be more careful next time. I promised! I will repeat this one.

Tinkering with the Chopped and Dried Mangosteen Peels

I think I did something wrong with the mangosteen peels I dried before. It was perfectly dried based on my senses. However, it became too hard to pound in mortar and pestle. It gonna break the ceramic and it would take forever with a wooden one. I could barely break a piece with my teeth. I would have a hard time converting it to smaller pieces with a manual corn mill either. I should have chopped it to smaller pieces when still fresh. On the other hand, it was not the time for regret. Re-wetting, re-chopping and re-drying was not a good option.

chopped dried mangosteen peelsDo not worry too much about the size if a commercial heavy duty mill is available. It will will break it to pieces  regardless of the size and hardness.

The hot beverage preparation. Lazy mode. I dropped all the dried mangosteen pieces in mug. Filled it with hot water from the hot and cold water dispenser and covered it. I know a hard wood flavor won’t disperse easily in water not as hot as boiling. I patiently waited almost fifteen minutes before opening.

What I saw next was not as nice as I was expecting. The solution became slightly brown with numerous yellow dots and some candle like specs floating on surface. The yellows came from the peels which I can see clearly. I have no idea bout the candle like specs.

infused mangosteen peelsI felt like drinking a wood infused water with slightly astringent taste. It was so different that what I drank before.

The peel pieces were sinking one by one as I drink.



I tried grinding it in manual corn meal. I set the burrs loose so I could easily turn the rotating handle. Too loose won’t be effective in reducing the particle size so I was tightening the burrs a bit for every run. I did over ten runs but  never attained what I wanted. Rotating the handle became harder and harder up to the point when I couldn’t turn it anymore.

Mangosteen Pericarp, From Sun Drying To…

It is obvious that I cannot possibly consume the rest of 12 mangosteen rind halves in a day or within a week.  The good thing I have in mind is dry them so it can be stored in shelf conditions.

mangosteen rind quartersSunshine is free. It is always there for the taking. It is up to us how we can make good use of it. Drying this mangosteen rind under the heat of yellow sun is my own little way of harnessing sun’s energy.

I patiently cut all the rind to small slices. This allows more surface area for moisture evaporation and thus faster drying.

Boiling The Mangosteen Rind

After savoring all the mangosteen fruits. Mangosteen which I bought from nearby public market. I tried making tea straight from the fresh rind.

I consumed all six fruits all by myself. I tried sharing the rest after finishing one fruit but they simply never liked it. The burst of extreme sweetness was a turn off for them. They would like it better if it tasted sweeter and less sour.  Whatever, the flavor was fine for me. It was a lot better than a sour santol fruit.

mangosteen rindsI browsed the web trying to find any specific instructions on how to prepare mangosteen tea straight from fresh rind. I got tired and only found procedures for commercially prepared tea bags and powders.  I had to do a DIY for myself.

Preparing a cup. Whole rind for a cup might be too much. Half-rind might be too much too. I decided to go with 1/4 rind. Placed the rind in pan. Added two cups water and boiled for 30 minutes.

Too much might hinder absorption. Thirty minutes boiling time was half of what a reader suggested on “How to Make Mangosteen Tea” article and it is the time when I observed a significant color change. Half of the water evaporated and only resulted to one cup as expected.

Mangosteen, In The Flesh

Wow! Mangosteen.

mangosteen fruitsHow much?

It cost 100 pesos per kilogram.

Where did it came from?

The seller said it came from Davao. Okay. I get it. It traveled all the way from Davao to Indang. It explains why it cost so much. Adding the fact that it is a well-known health fruit.  I cannot imagine how much it will cost me if I travel to Davao just to buy mangosteen.

I bought half kilo for the price of 50 pesos. About six pieces mangosteen fruits. I think the price is not as expensive as I thought, considering the price of locally produce dragon fruit is about as much.

The seller reminds me that I am really paying for the peels and not for the flesh. I feel that she is true to her words. She is keeping several peels on her side. I also read many articles about this mangosteen. The fruit is valued for its peels. Drinking tea extracted from peels is a good habit.

The large stalks are obviously included in price computation. I hope they are healthy too.

The dark read skin looks tough but it is soft and can be readily broken with bare hands. Inside are several seeds which have close resemblance to santol. Small seeds have no real seeds while the large have, see image below. The white cottony pulp  gives a sudden burst of extreme sourness and a mild sweet taste in the end.

Mangosteen Xanthones Tips and Some Laboratory Studies


I am looking for mangosteen tea preparation steps. Tips on how to steep/boil fresh skin or dry rind. The specific temperature for how many minutes or hours. However, I found out that xanthones, the dominant and most important mangosteen antioxidant, is relatively heat stable. Maybe boiling it is fine or steeping might be better.

Here are the other tips I found around the web. Most of them are supported by scientific studies.

1) Long term moderate consumption is recommended. Xanthones are absorb only in small amounts. Large doses are not beneficial and tend to lower absorption efficiency.

2) Aside from xanthones, it has other beneficial substance like catechins, polysaccharides, proanthocyanidins and sterols.

3) Oven drying 60ºC is recommended for maximum retention of sensory qualities.  Addition of whey powder is preferred over maltodextrin – it helps maintain xanthone content and improves its solubility.

4) Xanthones when taken with a high fat meal. Showed that xanthones in mangosteen juice are absorbed when ingested along with a high-fat meal, although release of xanthones from pericarp particles during digestion may be limited.

Some Health Benefits supported with laboratory studies…

2) Twenty seven oxygenated xanthones showed anti-fungal activities against strains of Candida, Cryptococcus, Aspergillus.  The 1,2-dihydroxyxanthone was found to be the most effective.
