1, transportation damage occurred during delivery or transportation.
The yellow substance on the stem of mangosteen is actually a substance secreted by mangosteen itself, which is likely to be damaged during picking. It may also be damaged and squeezed during transportation, resulting in broken skin. It will lead to the secretion of yellow mucus, which is harmless to our human body. There is no need to worry too much about this situation.
Of course, if the broken skin is exposed for too long, it will seriously affect the taste of mangosteen and make it no longer fresh. So when you choose mangosteen, you can have a look. If there is a lot of yellow substance on its pedicle, it means that this mangosteen is not very fresh.
2. Mangosteen is not ripe yet
Yellow pulp will also appear in immature mangosteen, which is harmless and edible. But it tastes bad. You can pick up mangosteen and pinch it when you choose. If it is soft, it means the mangosteen is ripe. If it is still hard, it means it is not ripe. Mature mangosteen, the skin will be softer and the head will be bigger. Some mangosteen peel is purple-black, so you can choose to peel it and taste it. Immature mangosteen tastes bitter.
Mangosteen has been stale for too long.
Another possibility is that mangosteen has been placed for too long, which leads to the deterioration of the pulp inside, so it will appear yellow. If you buy stale mangosteen, the so-called pulp will appear. At this time, the mangosteen tastes bitter. The taste is very bad, because the price of mangosteen is relatively high, so if there is a small piece of yellow, you can remove the yellow and eat the white one. But if the skin is rotten, it is best not to eat it. This is not good for your health.
Mangosteen origin:
Mangosteen is native to Malay Peninsula and Malay Archipelago, and is widely planted in Southeast Asia such as Malaysia, Thailand, Philippines and Myanmar. At present, Thailand is the country with the most mangosteen.
In fact, the mangosteen we usually eat mainly comes from Thailand. Mangosteen is widely cultivated in tropical and subtropical regions, but it does not include China. Due to the influence of climate conditions in China, mangosteen has not been planted on a large scale in China. Although it has been introduced in many places, it is still in the trial planting stage.
Among them, Taiwan Province, Fujian, Guangdong, Guangxi, Yunnan and other areas with mild climate and small temperature difference between day and night are the main trial planting sites of Mangosteen in China. As far as the current planting situation is concerned, the annual output is not ideal, and most of them still rely on imports, so it is necessary to further improve and improve the planting technology.
