Pineapple originated in the Amazon River valley of Brazil and Paraguay in South America, and was introduced to China from Brazil in the16th century. Now it has spread to the whole tropical region. Its edible part is mainly composed of inflorescence axis with increased meat quality and flowers arranged spirally around it. Flowers are usually not strong, and persistent flowers are surrounded by lobes in a cavity in which atrophied stamens and styles are hidden. The fiber of leaves is very tough and can be used in textile, rope making, netting and paper making.

Pineapple and pineapple are biologically the same fruit. China Taiwan Province province is called pineapple, and Chinese mainland is called pineapple. In the fruit market of Chinese mainland, pineapple generally refers to Kane species, mostly imported, while pineapple generally refers to Balinese species, mostly made in China. However, in Taiwan Province Province, China, both the Kane species and the Balinese species are called pineapples. After peeling the pineapple in Bali, there are "internal thorns" to be removed; However, after Cain planted the pineapple, there was no "internal thorn" and it was not necessary to draw a ditch. In terms of flavor, Bali is better than Cayne, but only Cayne is imported for transportation reasons.

Pineapple is flat, sweet, slightly sour, slightly astringent and slightly cold. It has the effects of relieving summer heat, quenching thirst, promoting digestion, relieving diarrhea, invigorating spleen and stomach, strengthening vitality, invigorating qi and blood, promoting digestion, eliminating dampness, beautifying and slimming. It is a seasonal fruit for both medicine and food in summer, but it is not advisable to eat too much at a time. (Li Shizhen's Compendium of Materia Medica)

Edible

As a fresh food, pineapple is golden in color, rich in fragrance, sweet and sour, crisp and juicy. Pineapple fruit is mostly used for canning except fresh food, and is widely loved because it can keep its original flavor. Canned pineapple is known as "international canned fruit" and can also be made into a variety of processed products, which are widely welcomed by consumers.

Pineapple, like some fruits, can make some people allergic, and the allergic reaction can appear within 15 minutes at the earliest. This symptom is called "pineapple disease" or "pineapple poisoning". For example, abdominal pain, diarrhea, vomiting, headache, dizziness, skin flushing, itching all over the body, numbness of limbs, mouth and tongue, dyspnea, shock and other serious allergic reactions.

Before eating, the pineapple is soaked in salt water, and some organic acids contained in it can be decomposed in salt water to remove the sour taste and make the pineapple taste sweeter. You can also scald it with boiling water before eating. Bromelain began to denature at 45℃~50℃, and more than 90% was destroyed at 100℃. After cooking, the taste is also improved. Don't eat too many pineapples at a time. Excessive consumption is harmful to the stomach. The baby who eats for the first time only eats the size of a biscuit. If there is no abnormality, the amount can be increased appropriately next time.
