Can I let the apple ripen if I pick it before it's ripe

Apples are usually ripe when picked. Immature apples can still continue to ripen after harvesting through the release of ethylene gas, but there may be differences in taste compared to naturally ripe fruits. The main factors affecting the ripening effect include storage temperature, ventilation conditions, fruit integrity, ethylene concentration, and variety characteristics.

Place unripe apples at room temperature, maintain good ventilation, and avoid direct sunlight. The ripening process usually takes 3-7 days to complete. Apples themselves release ethylene gas to accelerate ripening, and storing them together with other fruits with high ethylene content such as bananas and kiwis can promote this process. When storing, it is necessary to ensure that the skin is not damaged, otherwise it is prone to decay and deterioration. There are differences in the ripening speed of different varieties of apples, for example, Fuji apples have a longer ripening cycle than Gala apples. If the maturity of apples is too low during harvesting or the storage environment temperature is below 10 degrees Celsius, it may result in the inability to ripen properly. refrigeration can inhibit ethylene activity and keep the fruit in a stiff state for a long time. Some early picked apples have insufficient starch conversion, resulting in insufficient sweetness even after softening. When encountering such situations, apples can be sliced and used for baking or cooking, avoiding direct consumption of sour and astringent fruits.

When storing unripe apples on a daily basis, it is recommended to wrap them in paper bags to maintain humidity and regularly check for signs of decay. Mature apples should be consumed or refrigerated in a timely manner to avoid excessive softening. For large quantities of apples that cannot be consumed in the short term, processing products such as jam and dried apples can be considered to extend their shelf life. If mold or odor is found on the surface of the fruit, it indicates that it has spoiled and needs to be discarded.
