-Fruit shape has been included by many international and national standards of kiwifruit grading as a minimum requirement using the word “well formed” [17,18]. The width/thickness ratio is also used in many kiwifruit grading standards to assess fruit shape besides the minimum requirements of well-formed fruit. Concerning the marketing and commercial quality control of kiwifruit, for example, the United Nations Economic Commission for Europe (UNECE) standard FFV-46 [18] and East African standard CD/K/013:2010 [17] classify fruits into three grades based mainly on fruit weight and ratio of minimum diameter of the equatorial section (MiDES, same as thickness in other studies) to maximum diameter of the equatorial section (MaDES, same as width in other studies) in addition to minimum and maturity requirements.

-However, most kiwifruit grading standards in China are applied to sort kiwifruit in different grades using fruit weight without the fruit shape. For example, NY/T 1794-2009 standard [19] classifies kiwifruits into three grades according to their skin damage and weight, and DB440300/T 25.7-2006 standard [20] divides kiwifruits into three grades only by their weight [21]. Consequently, Chinese fruit companies rely on those standards to grade kiwifruits and send them to the domestic market [22]. This poor grading system in China results in low exportation and shares in international kiwifruit markets. It is urgent to improve the sorting lines of kiwifruits in China using fruit shape based on the international standard so as to expand the exportation.

Product Description
General Information

-The kiwi is native to the Yangtze River valley of northern China and Zhejiang Province on the coast of eastern China. The first seeds were brought out of China by missionaries to New Zealand at the turn of this century. Early nurserymen in New Zealand, such as Alexander Allison, Bruno Just, and Hayward Wright, recognized the potential of the fruit and it soon became a popular backyard vine. Several plants were sent to the Chico Plant Introduction Station in California and exist to this date. In addition to New Zealand and California, kiwifruit is also grown commercially in such areas as Italy, South Africa and Chile.

-The oval, ovoid or oblong fruit is up to 2-1/2 inches long, with russet-brown skin densely covered with short, stiff brown hairs. The flesh, firm until fully ripe, is glistening, bright green or sometimes yellow, brownish or off-white, except for the white, succulent center from which radiate many fine, pale lines. Between these lines are scattered minute dark-purple or nearly black seeds, unnoticeable in eating. The flavor is sweet/tart to acid, somewhat like that of the gooseberry with a suggestion of strawberry.

- The most common species include Hayward (Actinidia deliciosa) Hardy Kiwi (A.arguta, A. kolomikta), Chinese Egg Gooseberry (A. coriacea), Red Kiwi (A. melanandra), Silver Vine (A. polygama), Purple Kiwi (A. purpurea).

-Fresh kiwi works well in many recipes including cocktails, gazpachos, meat dishes, salads, salsas, smoothies and more. Kiwi has been processed into products such as baked goods, candies, ice cream, jam, juice, puree, popsicles, as well as beauty products. Kiwi also freezes well, retaining much of its flavor (CA Kiwifruit Commission – Freezing Kiwifruit, n.d.).
