Kiwi fruit is familiar to us all. Most kiwis sold in markets tend to be quite "unripe." These hard kiwis actually don't offer the best taste—they're often quite sour.How to ripen kiwifruit? Some friends may not know how to ripen kiwifruit. Below, we recommend methods for ripening kiwifruit. Kiwifruit lovers, why not try these handy tips?Experts advise that kiwifruit must be fully ripe before consumption. This isn't just because unripe kiwis taste unpleasant—they also contain low sugar levels and high acidity. Regularly eating them may break down proteins in your tongue and oral mucosa, causing discomfort. This occurs because unripe kiwis contain high levels of protease enzymes.Below, we introduce methods to ripen kiwifruit, hoping they prove helpful.
Methods for Ripening Kiwifruit: The following techniques can be used to accelerate ripening:
1. Increase ethylene concentration to promote post-harvest ripening.
Place fresh kiwifruit in a plastic bag along with a cut pear or apple. Seal the bag and leave it for 3–5 days until the fruit ripens.Generally, use one cut pear or apple per kilogram of kiwifruit. The more fruit added, the better the ripening effect. Once ripened fruit softens, peel and consume. For fruit that remains too firm to peel, cut off the skin before eating.
2. Increase the storage temperature.
Post-harvest ripening is necessary for kiwifruit consumption. Ripening duration depends on initial ripeness and environmental conditions. Higher ripeness or warmer temperatures shorten this period. Elevated storage temperatures accelerate fruit metabolism and hasten ripening.
3. Insert several toothpicks into the kiwifruit.
After two days, the fruit will soften considerably. Experts explain this occurs because the "wounds" created by the toothpicks stimulate ethylene production in the fruit, accelerating ripening.
Kiwifruit Tips:
High-quality kiwifruit typically feature a regular shape, weighing 80-140 grams each. They are mostly oval-shaped with a smooth, unwrinkled surface. The calyx is small, round, and indented inward. The skin exhibits an even, glossy yellowish-brown color, and the fine hairs are delicate and resistant to shedding. When cut open, the flesh is vibrant green, offering a delicious sweet-tart flavor.
Kiwis are highly storable fruits, typically maintaining freshness for 3-6 months when refrigerated at 1-5°C.
