Pineapples are juicy, sweet, and sour, with a pleasant aroma. The acidic butyl ester in them stimulates salivation and has an appetizing effect.
The pineapple also contains a variety of enzymes that help to break down proteins and promote digestion, making people more appetizing. Especially after eating greasy food, eating pineapple can not only relieve greasiness but also promote the decomposition and digestion of proteins in food.
Pineapple has a water content of over 80% and is also rich in dietary fiber, which lubricates the intestinal tract and promotes peristalsis, speeding up the discharge of harmful substances from the body, thus preventing dry stools and relieving constipation.
In addition, pineapples contain a variety of biological enzymes that help break down proteins in food and speed up the passage of food through the intestines, helping to prevent food accumulation and constipation.
Many people eat pineapple by soaking it in salt water for a while, why is this?
Pineapples contain a highly active "pineapple protease", which contains at least 5 protein hydrolases. While we revel in the sweetness of the pineapple between our teeth, the enzyme also quietly breaks down the proteins in the mucous membrane of our mouth, tongue, and esophagus, causing a tingling, stinging sensation in our mouths.
In addition, pineapple contains glycosides, 5-hydroxytryptamine, non-protein hydrolase, acid phosphatase, peroxidase, amylase, etc.
These substances hold together to cause irritation to one's skin and oral mucosa, causing itchy skin or allergies. There is a paragraph that says: "You are eating the pineapple and the pineapple is eating you", talking about this truth.
Experiments have shown that salt water can inhibit the activity of pineapple protease and reduce the leaching of glycosides. When pineapples are soaked in salt water at a concentration of 7% for 10 minutes, they lose fewer nutrients and have a better taste and flavor.
The pineapple is suitable for tropical and subtropical areas and prefers a warm and humid growing environment. It needs sufficient water when being maintained and can grow in areas with an annual rainfall of 500-2800mm, with 1000-1500mm evenly distributed being the most suitable.
The plant has a self-regulating function that reduces transpiration intensity, slows respiration, and conserves water in the leaves to maintain life activities; when there is a serious water shortage, the leaves are red and yellow and must be irrigated in time to prevent drying out; too much rain and high soil moisture will cause root rot and plant heart rot or withering.
Drainage is, therefore, necessary after heavy or stormy rainfall. It is best to have plenty of sunlight to help it grow, as it originates from the tropical mountains of Brazil, Argentina, and Paraguay. It is cultivated in more than 60 countries worldwide.
