Passion fruit contains a variety of aromatic substances, rich in nutrients, high vitamin A and C, and minerals such as magnesium, phosphorus, iron, potassium, and zinc, and is known as the "king of fruit juices". The flesh of passion fruit is yellow and contains a lot of flavonoids, which have antioxidant and anti-cancer effects, and are natural anti-inflammatory agents. Passion fruit is rich in carotene, which helps protect eyesight and skin. Passion fruit is a low-glycemic fruit that will not cause sudden rise in blood sugar after eating, thus ensuring a stable blood sugar level. Although it tastes sour, it will produce an alkaline effect after digestion, so it is an "alkaline fruit" and has a positive effect on the human body. Passion fruit can be eaten directly or used to make beverages. Cutting a passion fruit, you can see its rich pulp, which can be mixed with other drinks to add fragrance. Fresh passion fruit has a sweet and sour taste, which can stimulate appetite; you can also leave passion fruit for 2 to 3 days, and when the peel becomes wrinkled, its acidity will decrease and the fragrance will be stronger.
Passion fruit grown at farms in Puli, Nantou County, Taiwan, due to its geographical location with mild climate and excellent water quality, and at an altitude of more than 600 meters, the temperature difference between day and night in the environment makes the passion fruit more sweet and delicious. The central mountain range serves as a natural barrier to avoid the damage caused by typhoons to crops. The farms use net room and hanging net technology to reduce insect and water damage, improve fruit sweetness, and return to natural farming methods such as organic fertilizers, natural enzymes to moisten the soil, and self-raising bees for pollination, so as to grow more nutritious, healthy and sweet passion fruit.
