How to buy fresh and healthy vegetables and potatoes
Try to choose a round one. If there is no broken skin, the rounder the better. The skin must be dry and not blistered, otherwise the storage time will be short and the taste will be bad.
Potatoes that sprout already contain toxins and are not suitable for eating. If you find that the potato skin turns green, don't eat it even if it is very light green.
Because the green of potatoes is a sign of the existence of toxic alkaloids, eating them will be poisoned.
aubergine
The tenderness of eggplant has a great influence on the quality. A reliable way to judge whether an eggplant is old or tender is to look at its eyes. Size? .
Eggplant? Eyes? Where does it grow? Where the sepals of eggplant are connected with the fruit, there is a pale green white band ring, which vegetable farmers call eggplant? Eyes? .
The bigger the eyes, the more tender the eggplant, and the smaller the eyes, the older the eggplant. Tender eggplant feels sticky in your hand, and hard eggplant is old eggplant.
pepper
Pepper is much more spicy, and the finer the pulp, the more spicy it is.
Persimmon-shaped round peppers are mostly sweet peppers. The thicker the pulp, the sweeter and more brittle it is, and the semi-spicy is somewhere in between.
If you pay more attention to nutrition, you can buy red pepper to eat, because red pepper has 0.8 times more vitamin C and 3 times more carotene than green pepper, and red pepper is light (small proportion).
It is also economical, but the taste is not as crisp as green pepper.
cucumber
No matter what variety, cucumber should be tender, and it is best to have flowers (the corolla stays in the navel). At the same time, choose hard ones.
Because the water content of cucumber is 96.2%, fresh melon strips are always hard and will become soft after losing water.
But hard is not necessarily fresh. Because soaking softened cucumbers in water will rehydrate and harden.
It's just that the navel of the melon is still a little soft, the surface of the melon is dull, and most of the remaining corollas no longer exist, so it's easy to identify when you buy it.
Chinese yam
No matter what variety you buy, the skin of tuber is the focus of selection. Only when the skin is smooth and free from abnormal spots can you buy with confidence.
As long as there are any abnormal spots on the epidermis, it means that the disease has been infected and the edible value has decreased.
tomato
To buy tomatoes, we must first find out whether they are eaten raw or cooked.
If you want to eat it raw, of course, buy pink, because this tomato has a faint sour taste, and it is better to eat it raw;
If you want to eat cooked food, you should buy red tomatoes as much as possible. This kind of tomato has a strong flavor and is good for making soup and cooking.
Especially if you don't buy green tomatoes? Green shoulders? Tomato (with blue pedicel), because this kind of tomato has poor nutrition and contains toxic lycopene.
