Is it normal for blueberries to be green when bitten open

It is normal for the meat of blueberries to turn green after being bitten open, which may be related to the variety characteristics, maturity, or planting conditions. When some blueberry varieties are not fully ripe, the flesh tends to be green, and after maturity, it turns light yellow or white; In rare cases, color abnormalities may occur due to improper storage or variations in variety. The color of blueberry flesh is significantly affected by variety differences, for example, some high bush blueberry varieties still have a green tone in their flesh after maturity, which is a natural feature. The deep blue color of the skin of these blueberries is due to the accumulation of anthocyanins, but when the chlorophyll in the flesh is not completely degraded, a green white alternation occurs. Insufficient light exposure or early harvesting during the planting process can also delay the color change of the fruit flesh. At this time, the sugar acid ratio of the fruit is low, and the taste is slightly sour but there is no risk of consumption. In rare cases, the internal greening of blueberries may be related to mold growth or genetic mutations. If there are large areas of dark green patches, soft and rotten texture, or accompanied by an odor in the flesh, it may have spoiled. Some special hybrid varieties, such as pink lemon ade blueberries, have naturally yellow green flesh and are commercial breeding achievements. Consumers can judge the quality of blueberries by observing whether the appearance of the fruit is intact and whether the stem is fresh. Normal green flesh will not affect its nutritional value.

When choosing blueberries in daily life, it is advisable to prioritize fruits with full skin and even fruit powder. Refrigeration can delay the ripening process. If you have doubts about the color of the fruit pulp, you can cut multiple blueberries and compare them for observation. When there are significant differences in the color of the same batch of fruits, it is recommended to consult the merchant to confirm the variety characteristics. Blueberries are rich in anthocyanins and vitamin C. Moderate consumption can help with antioxidant properties, but individuals with gastrointestinal sensitivity need to control their single intake to avoid discomfort.
