Must pineapple be soaked in salt water to eat? The editor of this article will tell you why pineapple should be soaked in salt water and other ways to eat pineapple.
Why does pineapple soak in salt water?
Pineapple is a kind of seasonal fruit with both medicine and food. It is rich in vitamins A / B / C, minerals, fructose, glucose, crude fiber, organic acids, carotene and other nutrients. It has the effects of eliminating food and greasiness, detumescence and diuresis, reducing fat and weight, generating saliva and quenching thirst. But you may not know that pineapple also contains two harmful components - glycosides and pineapple prion enzyme.
Many people have a series of allergic reactions such as numbness of mouth and tongue, red and itchy skin, diarrhea, vomiting and even shock after eating pineapple for about 15 minutes to 1 hour, which are caused by these two substances. Glycosides and pineapple prion enzymes in pineapple have a strong stimulating effect on human lips and oral mucosa. Eating untreated pineapple will make people itch and sting in the oral cavity. Maybe you don't feel much when you eat one, but if you eat two more, you will feel numbness in your tongue and tingling in your mouth. Salt water immersion can inhibit the activity of these two harmful components in pineapple, reduce sensitizing substances, and will not cause strong irritation to the mouth and lips. At the same time, sodium ions in salt can also inhibit the acidity and bitterness in food, so pineapple soaked in salt water tastes sweeter.
However, it should be noted that if the pineapple is soaked in salt water for too short, most of the sensitizing ingredients are still there, which can not play an anti allergic role; If the soaking time is too long, the rich sugars in pineapple are easy to breed and promote bacterial growth, which will not only affect the taste, but also be harmful to health. Therefore, it is recommended to peel and slice the pineapple, soak it in salt water for about 30 minutes, and then wash the saltiness on the surface with cold water, so that it tastes better.
In addition to brine bubble, how can fresh pineapple be treated?
In fact, the way to desensitize pineapple is not only brine bubble, but also hot with boiling water. Because the environment of acid, alkali, low temperature and high temperature will make the enzyme lose its activity or weaken its activity. The temperature reaches 45 DEG; C. Pineapple prion enzyme began to denature and lost its function, 100 & deg; At C, more than 90% of enzymes are destroyed, and glycosides will be destroyed and eliminated at the same time. This method is better than saline bubble in eliminating sensitizing substances. The pineapple can be sliced and heated to 60 DEG in clear water; C and maintain it for a period of time, and then cool down. If you are afraid of acid, add a little rock sugar and cook it together to taste better. Finally, Xiaobian should warn everyone that people who are allergic to pineapple had better not eat pineapple to avoid allergies, so as not to lose more than they gain&# 8203;
