When some people buy strawberries and put them into the water, they find that the water turns red, does this mean that the strawberries are dyed?
Many people worry that strawberries with white flesh are unhealthy, is this true? Let's learn more about strawberries together.
1. It is normal for strawberries to lose color when washing
The color of red strawberry comes from the accumulation of anthocyanin in the cell vesicles of strawberry.
Due to the different content of anthocyanin, strawberries will show obvious color change, the more anthocyanin, the more red strawberry.
Anthocyanins are natural pigments that are harmless to humans and have a high nutritional value.
It is found in almost all fruits with brighter colors, such as mulberries and prunes.
And strawberries lose color when washing because the epidermis is broken and the anthocyanins rich in the peel penetrate the water, which is a very normal situation.
2. The color of strawberries is different depending on the variety
Whether the flesh of strawberries is red or white depends on the variety.
The white color of strawberries is due to the reduction of anthocyanin synthesis in these varieties of strawberries, which is achieved through traditional cross-breeding.
3. White strawberries have no safety problems
In the process of natural reproduction of strawberries, a natural variation of white color was discovered, and the staff cultivated this type of white strawberry variety through various breeding methods such as cross-breeding.
The white strawberry contains the same genes as the red strawberry, which is due to the natural variation of anthocyanin gene expression weakened during the process of group culture, and has nothing to do with genetic modification, and there is no safety problem that consumers are worried about.
4. It is recommended that consumers wash and eat correctly
The delicate strawberries are not protected by their peel, so they can be easily damaged, infected with microorganisms, and spoiled.
It is recommended to clean strawberries in three steps:
(1) Use running tap water for a few minutes to remove most of the germs, pesticide residues, and other contaminants on the surface of the strawberry.
(2) Soak the strawberries for 3 minutes.
(3) Rinse again with running tap water.
It is worth mentioning that strawberries contain fruit acids, which can stimulate the gastric mucosa to secrete gastric acid and cause gastrointestinal discomforts such as abdominal pain, bloating, and diarrhea if eaten in excess.
Also, strawberries are an acidic fruit, containing oxalic acid and benzoic acid, which may cause a decrease in the hardness of the tooth surface and lead to sour teeth if eaten in excess.
Therefore, even though strawberries are delicious and nutritious, it is important to eat them in moderation.
