The kiwifruit is a fruit of ovoid shape, of variable size and covered by a thin, brown, slightly hairy skin. It may be 4 to 7.5cm long, and 3.5 to 5cm wide. The weight ranges from 30 to150g, according to variety, climatic conditions, and the culture system. The pulp may be of different green tonalities according to the variety. It is also tender, juicy and bittersweet in flavour. It presents numerous small, edible black seeds. The colour of the pulp and the delicate flavour, somehow reminiscent of the grape, strawberry, and pineapple, make kiwifruit very pleasant.
Kiwi is consumed as fresh fruit, in fruit salads, salads or as garnish for different dishes. In order to consume it as fruit, it can be peeled or cut in half and eaten with a spoon. It contains an enzyme called actinidine that degrades proteins, reason why this fruit is used to soften the meat before cooking and thus reduce to the time for baking, rubbing the pulp of the fruit. Moreover, the actinidine prevents the coagulation of the jelly and it is the responsible of the bitter taste of some dairy products when they are mixed with kiwi. Kiwis are also cooked, tossed with butter, used as a bittersweet sauce or included as garnish for meat dishes. Jam, sherbets, iced drinks, confectionery products and liquors with or without alcohol are also made of this fruit.
Kiwis represent an excellent source of vitamin C, almost twice the content of some citruses. They are also rich in minerals like potassium, iron and calcium.
Kiwis are found all the year round because the different producing country take over the harvesting periods of each other: from mid May until the end of November, in New Zealand; the rest of the year in the Mediterranean countries, Chile and in California and Australia too. It is a product that has undergone a commercial development in the last few years, thanks to an excellent marketing campaign carried out by New Zealand, an example of how to present " a new product’.
Kiwis may last up to 6 months and their maturation is slow, at environmental temperature, although we accelerate it if we store them together with apples or bananas, that give off ethylene; however, we must avoid their contact if we want to slow down the maturation process and thus extend the period of preservation. Kiwi is a climacteric fruit whose intensity of transpiration is influenced and correlated to the presence of ethylene in the environment or that of endogenous origin.
