Why is the skin and flesh of the red pomelo red

The red color of the skin and flesh of the red heart pomelo is mainly related to the accumulation of natural pigments such as carotenoids and lycopene, which is a normal phenomenon. This type of pigment has antioxidant properties, is harmless to the human body, and may be beneficial to health. The red flesh of the red pomelo is due to the accumulation of high concentrations of carotenoids and lycopene in the flesh. These natural pigments are commonly found in citrus fruits, but the red pomelo has a stronger synthesis ability due to its variety characteristics. Carotenoids are precursors of vitamin A, while lycopene has the ability to scavenge free radicals, both of which require fat assisted absorption. The color depth of red pomelo is affected by factors such as planting environment, lighting conditions, and maturity. Generally, the higher the maturity, the more vibrant the color. In rare cases, abnormal redness of grapefruit pulp may be related to improper storage or microbial contamination. If uneven color of the flesh is found accompanied by odor, mold, or softening texture, it is not recommended to consume. A normal red pomelo should have a fresh citrus aroma, with plump flesh particles and abundant juice. When making a purchase, you can observe whether the fruit stem is fresh and whether the skin is smooth without dents. When storing, it should be placed in a cool and ventilated place to avoid moisture.

Red pomelo is suitable for daily fruit consumption and is recommended to be paired with nuts or dairy products to enhance the absorption of fat soluble nutrients. It is advisable to control the daily intake at 200-300 grams, and people with gastrointestinal sensitivity should avoid eating on an empty stomach. If you are allergic to citrus fruits or taking specific medications, you should consult a physician before consumption.
