Ripe blueberry peel is dark purple or blue-black, covered with hoarfrost. Red blueberries are immature and are generally used to make salads and other dishes; The frost is not obvious or there is no frost, which means that it is not fresh after a long storage time; If it is black, it means it is fake.
2. shape.
Natural blueberries are small, with an average fruit weight of 0.5~2.5g and the maximum weight of 5g, so the bigger the blueberries, the better. Good blueberries are round, uniform in size, smooth in skin and non-sticky; Uneven size and rough epidermis indicate dysplasia.
3. pulp.
Pinch it with your hand, and the good blueberry fruit will be very strong; If it is soft to pinch and there is juice oozing, it means it has been cooked; If the pulp is dry and the epidermis is wrinkled, it means that it is not suitable for purchase because of long storage time and serious water loss.
4. Taste.
Good blueberry has a strong aroma, sweet and sour taste and no stone; If the fragrance is light and tastes sour, it means it is not mature yet; This big stone is fake and should not be bought.
