Why are some durians bitter? Why is durian a little bitter?

Under normal circumstances, the bitterness of durian meat is caused by overripeness, if it is sweet with a little bitterness, it is normal, if it still has the smell of wine, it is estimated that it has deteriorated, and it is best not to eat. In addition, the color of the flesh of fresh and ripe durian is a tender yellow appearance, and there is a natural aroma after opening, but some durians will find that the flesh has changed color, some are black, and the smell is also disgusting, so it can be concluded that this durian is a spoiled fruit and can no longer be eaten.

1.What's going on with the bitterness of durian: The bitter taste of durian is not spoiled, but because it is overripe or not ripe. Some high-quality durians have a sweet and bitter taste, so there is no big problem with durian being bitter, and you can still eat it.

Durian is bitter because the durian is overripe and is edible. After the durian is overripe, it will lead to the accumulation of sugar in the coarse durian, resulting in the phenomenon of durian bitterness, but it does not affect the consumption, if the durian is bitter and accompanied by a peculiar smell, Shenlu proves that the durian has deteriorated and can not continue to eat.

Durian pulp contains a lot of sugar, high in calories, contains protein, fat, carbohydrates, and is rich in vitamins, such as vitamin A, vitamin B, vitamin C, and rich in mineral elements, among which potassium and calcium content is the highest, and the amino acids in durian are also very complete, including glutamic acid, aspartic acid, etc., and contains plant active pre-antagonistic components, such as flavonoids, anthocyanins, etc.

The main reasons for durian bitterness are as follows:

1.Durian contains a higher level of tannin. Tannin is a bitter component, and durian contains a higher amount of tannin, which is the main part of its bitterness**. Tannins have a fresh-keeping effect and can prevent corrosion and oxidation, but their bitterness is more obvious.

2.Durian contains more phenolic compounds. Phenolic compounds also have a certain bitter taste, and durian contains a certain amount of phenolic acids, tannic acids and other compounds, which also aggravates its bitter taste.

3.Other ingredients in durian also have a bitter taste. Durian also contains a certain amount of riboflavin, canavalin and other compounds, which also have a certain bitter taste, which is also one of the most bitter tastes of durian.

4.The chemical reaction that occurs during the ripening of durian also produces bitter substances. During the ripening process of durian, a certain quality of starch residue will be broken down into sugars by enzymes, and a certain amount of by-products such as phenylpropanol, etc., which also have a bitter taste, which aggravates the bitter taste of durian.

5.Differences in personal perception are also a factor. Different people have different sensitivities to bitterness, some people are more sensitive to bitter substances such as tannins, so they feel that durian is more bitter, while others may not feel too bitter due to sensory differences, which is also affected by personal taste.

In summary, the bitterness of durian is mainly caused by the high content of its characteristic and bright compounds such as tannin and phenolic compounds, and a certain amount of bitter compounds are also produced during the ripening process, which aggravates its bitterness. However, differences in personal taste also affect the perception of durian bitterness to a certain extent, making people's evaluation of its bitterness different. By improving and other measures, reducing these bitter components can also reduce the bitterness of durian and improve its flavor, which is also an important means of durian processing.

Not all varieties of durian have a bitter taste, but some varieties of durian pulp will have some bitter taste. This is due to the increase in the amount of certain chemicals in the pulp after the fruit is ripe. For example, durian contains a product called "durian"."Triterpenoids"This substance increases as the fruit ripens.

Triterpenoids, on the other hand, give the flesh a bitter taste.

In addition, if durian is left for too long or transported for a long time, the chemicals in the pulp will gradually decompose, which will also cause a bitter taste. Therefore, if you want to eat durian Nakai, choose a fresh, moderately ripe fruit that can reduce the bitterness in the flesh.

The reason why durian is bitter is that it contains a variety of chemical compounds, one of which is a sulfide called "methionine". This sulfide is found in both the pulp and seeds of durian and is one of the contributing factors to durian's unique smell and taste.

In addition to sulfides, durian also contains a high concentration of sugars and fats. The digestion of these substances in the human body requires more energy, so durian is relatively easy to feel heavy and bitter in taste. In addition, the aromatic compounds contained in durian will emit a strong smell, which varies from person to person, and some people will find the smell too strong, pungent or unacceptable, thus affecting the taste perception of durian.

Scientists have done a lot of research on the composition and chemical properties of durian, such as analyzing the compounds and nutrients of durian flavor. Some studies have also found that durian contains higher concentrations of dust-opening acids such as acetic acid and lactic acid. These acids not only have an impact on the flavor and taste of durian, but may also be related to some of the health care functions that durian possesses.

Durian also contains more nutrients such as protein and fiber, which is beneficial to human health.
