1. Different nutritional values. In addition to its superior taste, the red heart dragon fruit has much higher nutritional value than the white heart dragon fruit. Red dragon fruit has a darker color and higher carotene content. Carotene is one of the most effective antioxidants against free radicals, helping to improve immunity and protect the fiber part of the eye lens.

2. The taste of red dragon fruit is slightly sweeter than that of white dragon fruit. This is because the soluble solids content of red pitaya is significantly higher than that of white pitaya, but there is no significant difference in titratable acid between the two. The solid-acid ratio (the ratio of soluble solids to titratable acid can reflect the sweetness of the fruit) is obviously slightly higher for red pitaya, so its sweetness is also a bit higher.

3. Red dragon fruit is rich in natural pigments. From the peel to the pulp, it is rose red to purple red, and this pigment is mainly β-anthocyanin. There is evidence in some in vitro experiments that β-anthocyanins have antioxidant (free radical scavenging), preventive and therapeutic atherosclerosis, and anticancer effects.

4. The prices are different. The price of red heart dragon fruit is higher than that of white heart dragon fruit. This is related to two reasons. On the one hand, the red dragon fruit on the market today is generally imported from Vietnam, and the cost is relatively high. On the other hand, consumers are no longer satisfied with common varieties of fruits, and high-end imported fruits such as red dragon fruit are becoming more and more popular.
