“…Significant differences in actinidin concentration exist among kiwiberry and kiwifruit species and cultivars. Generally, the amounts of actinidin in the three main species ( A. deliciosa , A. chinensis and A. arguta ) vary at 2.9–4.4, 0–5.7 and 1.6–10.7 mg/mL of fruit juice, respectively [ 30 ]. The protease activity measured for different kiwiberry cultivars varies appreciably from 25.7 to 114.0 nM p NA/min and is much higher than for kiwifruit (6.3–10.1 nM p NA/min) [ 30 ].…”

The kiwiberry (Actinidia arguta) is a new product on the market that is enjoying growing consumer acceptance around the world. This widespread interest has created increased demand for identification of the kiwiberry’s nutritional health benefits. Containing over 20 essential nutrients and a range of vitamins, the kiwiberry comes near the top of fruits classed as superfoods. It is one of the richest sources of vitamin C with up to 430 mg/100 g fresh weight (FW) and is considered the richest dietary source of myo-inositol (up to 982 mg/100 g FW). The kiwiberry is also one of the richest sources of lutein (up to 0.93 mg/100 g FW) in commonly consumed fruit. Furthermore, containing up to 1301.1 mg/100 g FW phenolics and significant amounts of the essential minerals of potassium, calcium and zinc, the kiwiberry rates very highly as a ‘healthy food’. The type and number of this fruit’s medicinally promising nutrients have motivated ongoing investigations into its antioxidant, anti-tumour and anti-inflammatory properties. Early research has pointed to the kiwiberry being a very promising treatment for some cancers and health issues involving the gastrointestinal system, hypercholesterolemia and certain cancers. A pharmaceutical composition of A. arguta, A. kolomikta, and A. polygama extracts has already been registered for the prevention and treatment of some immune (inflammatory) mediated diseases, as well as the treatment of some non-allergic inflammatory diseases. This paper reviews and highlights the limited nutritional and therapeutic information currently available on the kiwiberry, a minor fruit possessing such major properties.Electronic supplementary materialThe online version of this article (10.1007/s11130-017-0637-y) contains supplementary material, which is available to authorized users.

“…Some of the allergen molecules in kiwifruit have been reported (10). One of the major ones, actinidin (Act c 1), was also reported to be present in A. arguta (11)(12)(13). Although there have been few reports of the presence of kiwifruit allergen in A. polygama, the intake of A. polygama by patients with kiwifruit allergy might induce the allergy.…”

Kiwifruit (Actinidia deliciosa and Actinidia chinensis) is allergenic to sensitive patients, and, under Japanese regulations, it is one of the food items that are recommended to be declared on food labeling as much as possible. To develop PCR-based methods for the detection of trace amounts of kiwifruit in foods, two primer pairs targeting the ITS-1 region of the Actinidia spp. were designed using PCR simulation software. On the basis of the known distribution of a major kiwifruit allergen (actinidin) within the Actinidia spp., as well as of reports on clinical and immunological cross-reactivities, one of the primer pairs was designed to detect all Actinidia spp. and the other to detect commercially grown Actinidia spp. (i.e., kiwifruit, Actinidia arguta, and their interspecific hybrids) except for Actinidia polygama. The specificity of the developed methods using the designed primer pairs was verified by performing PCR experiments on 8 Actinidia spp. and 26 other plants including fruits. The methods were considered to be specific enough to yield target-size products only from the target Actinidia spp. and to detect no target-size products from nontarget species. The methods were sensitive enough to detect 5-50 fg of Actinidia spp. DNA spiked in 50 ng of salmon testis DNA used as a carrier (1-10 ppm of kiwifruit DNA) and 1700 ppm (w/w) of fresh kiwifruit puree spiked in a commercial plain yogurt (corresponding to ca. 10 ppm of kiwifruit protein). These methods would be expected to be useful in the detection of hidden kiwifruit and its related species in processed foods.

“…These fruits contain a high level of vitamin C [up to 185 mg/100 g fresh weight (FW)], which declines slightly during cold storage. Dietary fiber (2% to 3%) and proteolytic enzyme actinidin, which is similar to papain, has also been determined [13]. Among all the kiwifruit cultivars, Hardy kiwis can be considered as the richest source of lutein.…”

Kiwifruit is native to Asia and has become popular worldwide due to its sensory and nutritional properties. It contains high levels of bioactive compounds such as vitamin C vitamin E, flavonoids, carotenoids and minerals. Kiwifruits show a wide diversity in size, shape, fuzziness, flesh and peel color and flavor. The export of fresh kiwifruit has led to rapid expansion of kiwifruit industry through out the world. kiwifruit has become a commonly consumed fruit and is easily available round the year. Kiwifruit is largely consumed as fresh but it is also available in processed forms as juices, fortified drinks, candies, dehydrated and lyophilized products. Kiwifruit is also minimally processed to provide consumers with ready to eat products. Different preservation techniques have been used so far to preserve minimally processed kiwifruit. Here we are going to review some of these techniques.
