Strawberries are a very common and delicious fruit, let's learn some tips about them together.
Why are strawberries expensive?
1. Most fruits, such as apples, pears, bananas, etc., only need to be sown once to harvest several waves of fruits, but not strawberries, which need to buy seedlings again and reseed every year.
2. When strawberries are ripe, they are not easy to keep and the cost of transportation when selling them is high.
Why strawberries are very easy to spoil？
Because strawberries do not have a shell.
Most fruits such as apples, bananas, peaches, mangoes, and durian have an outer skin that wraps around the flesh, thus reducing the invasion of bacteria and resisting external damage.
Strawberries do not have outer skin, so they are very fragile and can be easily damaged and spoiled.
How to choose strawberries when buying？
1. Most of the normal mature strawberry seeds are golden yellow, if the seeds are red, the strawberry is likely dyed.
2. Strawberries are not hollow, The hollow fruit is likely caused by the excessive use of hormones, which makes the fruit grow too fast and the nutrient supply is insufficient.
However, it is also possible that the fruit is hollow because of the lack of boron element, which makes the fruit white and dry, or the overuse of nitrogen fertilizer and unbalanced fertilization.
3. Normal strawberries grown artificially are generally conical in shape.
Some strawberries are not conical in shape and are huge, which is likely to be strawberries with growth hormones.
How to clean strawberries？
1. Rinse the strawberries with plenty of running tap water without removing the strawberry tips.
The reason for not removing the strawberry stems before washing is to avoid contamination by pesticides and contaminants that can seep into the fruit through the stems during the rinsing process.
2. Soak in lightly salted water for 5 minutes. Light salt water has the function of degrading pesticides and sterilizing.
Strawberries are fragile and should not be scrubbed hard.
3. Rinse with running water for more than 30 seconds. Brine and rice water can be rinsed off.
