Kiwi storage
Worldwide production in 2010 amounted to almost 1.4 million tons, 30% of which came from Italy, with 27% from New Zealand, 17% from Chilli and 19% from North, Central and South America. The varieties Actinidiadeliciosa (var. Abbott, Allisson, Bruno, Hayward and Monty), Actinidiachinensis, Actinidiaarguta, Actinidiakolonikta and Actinidiaeriante are particularly popular for cultivation purposes.
The kiwi fruit has become a beloved favorite among many, from health-conscious individuals to avid gamblers who enjoy playing at online casinos, like Zodiac casino use Celtic-themed gambling games. With its vibrant green color and unique tangy flavor, the kiwi has garnered heaps of fans worldwide. But what may come as a surprise is that even those immersed in the world of gambling can't resist this healthy delight. For gambling enthusiasts who are also health-conscious, the kiwi fruit offers a guilt-free indulgence. Packed with essential nutrients like vitamin C, potassium, and fiber, it not only satisfies their cravings but also provides numerous health benefits. From boosting immunity to aiding digestion and promoting heart health, the kiwi fruit is truly a powerhouse of nutrients. And for those who love Celtic-themed gambling games, incorporating this nutritious option into their routine adds an extra touch of excitement and enjoyment.
Harvesting kiwis
The right moment for harvesting kiwis can best be determined by measuring refraction because this corresponds to ripeness and eating quality (in contrast to colour and firmness). In New Zealand they apply a minimum refraction level of 6.2%; fruits below this level are not good for storing and are less tasty when ripe. A higher level of 7-9% is advised if long-term storage is to take place.
Kiwis produce very little ethylene but are extremely sensitive to this gas. The manual harvest of kiwis must be carried out with great care as damaged fruits immediately increase ethylene production and this can cause problems for other fruits. In order to prevent the development of Botrytis, it is important to harvest in dry weather.
Pre-cooling kiwis
The pre-cooling process is not used everywhere; in California, it is best to cool the harvest as quickly as possible to 0ºC however, in New Zealand, a ‘curing’ process is used (2 days at ambient temperature and then cooled). Curing reduces the chance of rot (Botrytis) and prevents 'stem end rot’. Curing can lead to some moisture loss and may cause the stalk scar to dry out.
(CA) Controlled atmosphere / (ULO) Ultra low oxygen storage of kiwis
Under optimum storage conditions at a temperature of -0.5ºC and 0ºC and a relative humidity of 90 to 95%, kiwis can be stored for between 3 and 5 months. Controlled atmosphere storage extends the period for kiwis by 3-4 months and increasing levels of CO2 results in better retention of firmness.Reduction of the O2 level inhibits ripening. Flavour may deteriorate with an O2 concentration of lower than 1% and internal breakdown can occur with a CO2 concentration higher than 7%. For kiwis, the most important aspect under controlled atmosphere conditions is to use ethylene adsorbers to keep the ethylene level as low as possible.
