Kiwis, with their vibrant green flesh and tiny black seeds, are a nutritious and delicious addition to any diet. Packed with vitamins, minerals, and antioxidants, they are a great way to boost your immune system and support overall health. However, kiwis are also known to be quite perishable, which can make it challenging to keep them fresh for an extended period. In this article, we will delve into the world of kiwis and explore the best methods for keeping them fresh longer.
Understanding Kiwi Fruit
Before we dive into the techniques for keeping kiwis fresh, it’s essential to understand the fruit itself. Kiwis are a type of berry that belongs to the Actinidiaceae family. They are native to China and were initially known as Chinese gooseberries. Today, kiwis are grown in many parts of the world, with Italy, New Zealand, and Chile being among the top producers.
Kiwis are a delicate fruit, and their freshness depends on various factors, including the ripeness when picked, handling, storage, and ethylene production.
