The weather is getting hotter and hotter, and all the fruits are on the market. Every time I buy fruit for my daughter-in-law, I always choose the freshest one. During pregnancy, the taste changes greatly, and every time I want to eat something different. This time, my daughter-in-law wants to eat sour fruit to relieve the symptoms of tasteless mouth. When it comes to sour fruit, the first thing that comes to mind is pineapple. Every time I eat pineapple, my tongue can't stand the sour taste of pineapple. Eating too much may even make you tingle. Therefore, the fruit shop will recommend me to buy pineapples every time, saying that pineapples are delicious and more nutritious. In fact, pineapple and pineapple are very similar in appearance, so it is difficult to distinguish them. If you are not careful, you will buy it by mistake. In order to buy more suitable fruit, the difference between pineapple and pineapple was specially studied.

biological variability

Biologically speaking, pineapple and pineapple are actually a kind of fruit, but Taiwan Province and Fujian are called pineapples, Hong Kong is called pineapples, and Singapore and Malaysia are called yellow pears.

Differences in appearance

Although pineapple and pineapple are the same creature, pineapple is generally bigger than pineapple. The average weight of pineapple is 3-5 kg, while pineapple is only about 2-3 kg. In addition to their different weights, their skins are also different. The peel of pineapple looks small, while the peel of pineapple is bigger and fuller.

The difference between taste and taste

Pineapple tastes very astringent and can only be eaten after being soaked in salt water or baking soda water. Pineapple can be eaten directly after being peeled. The astringency of pineapple is obviously smaller than that of pineapple, and eating more pineapple will not have astringency.

The difference after peeling

After the pineapple is peeled, there are holes in it, which need to be removed before eating. However, after the pineapple is peeled, the holes are close to none, so it can be eaten directly.

Nutritional value of pineapple and pineapple;

Since they belong to the same fruit, their nutritional value is naturally the same. Pineapple (pineapple) pulp is rich in fructose, glucose and vitamin B, which can help the body replenish qi and blood. The sugar and enzyme contained in it have a certain diuretic effect, which is extremely beneficial to patients with nephritis and hypertension. In addition, pineapple (pineapple) has the functions of clearing away heat and quenching thirst, promoting digestion and eliminating dampness. It is a good fruit for medical treatment and food in summer.

Bromelain is high in common pineapple, so we will try to remove it. Today I will teach you two methods:

1. pineapple soaked in salt water:

Many people think that soaking pineapple in salt water is for sterilization, but it is not. Pineapples are soaked in salt water to inactivate bromelain. It is best to cut the pineapple into small pieces before eating, and then fully immerse it in salt water, so that the bromelain content in the pineapple will be greatly reduced and there will be no uncomfortable feeling when eating.

2. Pineapple cooked:

Generally, the protease of pineapple begins to denature at 45℃-50℃, and the protease is almost completely destroyed at 100℃, which is why everyone will not feel numb when eating pineapple rice.
