VARIETAL DIFFERENCES IN THE MINERAL COMPOSITION OF KIWIBERRY - ACTINIDIA ARGUTE (SIEBOLD ET ZUCC.) PLANCH. EX. MIQ
Kiwiberry, also called hardy kiwifruit, Actinidia argute ((Siebold et Zucc.) Planch. ex. Miq), is a new, commercially grown species. Kiwiberry is known for its frost resistance and relatively small, smooth skinned fruit that can be eaten whole, without peeling. Sometimes it is called a healthy fruit because it contains a lot of pro-healthy constituents such as vitamin C, lutein and phenolics. The mineral composition of five, most popular in Europe, kiwiberry cultivars (Ananasnaya, Weiki, Geneva, Jumbo, 74-49) was evaluated in three consecutive years and compared to Actinidia deliciosa Hayward (kiwifruit). The fruits were harvested at eating maturity stage. Sodium (Na) and potassium (K) content level was obtained using atomic absorption spectrometry (FAAS). Calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), zinc (Zn) and copper (Cu) content were measured with atomic emission ICP-AES, according to procedures of Analytical Center at Warsaw University of Life Sciences. Kiwiberry proved to be an important source of minerals, especially K, Ca, P and Mg and can be considered as a healthy fruit. The quantity macro elements reduces, according to: K > Ca > P > Mg > Na and microelements: Fe > Zn > Cu. The amounts of the minerals varied in genotypes of kiwiberry and the years of research, but the highest level of almost all the minerals was noted for the cultivar Ananasnaya. Despite some annual fluctuations, all the tested cultivars were richer in most of the minerals than Hayward fruit except for K and Cu.
