What is Kiwi?
Known in ancient China as Yang Tao, the kiwifruit earned its way in that culture not just for its flavor, but also its medicinal properties, which science has today substantiated in numerous areas. Introduced by missionaries in New Zealand in the early 20th century, then in the US in the late 1960’s, kiwifruit was first called “Chinese gooseberry,” although it’s doubtful that this moniker ever really stuck.
Luckily, kiwifruit got its new name – in honor of New Zealand’s native bird – from an enterprising food distributor, and its subsequent cultivation flew around the globe. Today, Italy, Chile, France, Japan, and the US are the highest producers of two varieties: green and gold. Kiwifruit is not only a scrumptious food, but is also used for its ability to tenderize meats, due to the compound actinidin.
Kiwifruit is a surprising little fruit, and is unlike any other. First, it’s small and light brown in color with a fuzzy skin surface. Inside, the fruit is not only lime green and studded with tiny black seeds in an oval pattern when sliced, but it’s also delicious, rather like the flavor of a strawberry. Peeled, sliced, and chilled, kiwifruit is an excellent addition to any fruit salad combination or by itself.

History Of Kiwi
Kiwifruit is native to north-central and eastern China. The first recorded description of the kiwifruit dates back to the 12th century China during the Song dynasty. As it was usually collected from the wild and consumed for medicinal purposes the plant was rarely cultivated or bred. Cultivation of the fuzzy kiwifruit spread from China in the early 20th century to New Zealand, where the first commercial plantings occurred. In New Zealand the fruit was developed into an agricultural commodity through the development of commercially viable cultivars, agricultural practices, shipping, storage and marketing. The fruit became popular with British and American servicemen stationed in New Zealand during World War II and later exported first to Great Britain and then to California. From New Zealand the commercial production of the fruit spread to other modern production centers in the 70s and 80s and back to China in the 90s. Kiwifruit is a national fruit of China. There are now major production centers in all quadrants of the globe.
