Storage and Transportation of Taiwan's Green Jujube

Storage and Transportation of Taiwan's Green Jujube

1. Overview Taiwan blue dates, also known as Indian dates, Burma dates, Chinese wolfberry dates, hairy dates, etc., are species of the genus Liriaceae, produced in India and China, Yunnan and other places, this is a world of about 100 species, China has Thirteen species, of which jujube and hairy date are more important in Fruit cultivation. In recent years, Taiwan Province of China has bred many new varieties, developed rapidly and planted more.
Taiwan's jujube is very nutritious and its fruit is spherical, oval or olive-shaped, green, light green or golden yellow, and its flesh is yellow-green. The maternity period is from winter to spring, and the spring season is February. The jujube-like hot dry climate in Taiwan is suitable for planting in tropical and subtropical regions where the altitude is less than 1,200 meters and the average annual temperature is above 18°C.
Taiwan's jujube has strong adaptability, good early yield, mature time coincides with the spring off-season fruit season, fresh and sweet and crisp, and can be processed into a variety of products, so it has good prospects for development.
2. Storage characteristics At normal temperature, Taiwanese jujube is highly susceptible to deterioration, water loss, and brittleness. It can have a longer shelf life at low temperatures.
3. The storage disease is mainly anthrax, a fungal disease that occurs in the leaves and post-harvest fruits. The surface of the fruit surface is lightly sunken. After the disease has been moisturized for 1 to 2 days, the lesion rapidly expands. The surface of the lesion grows near the pink mold layer. The mold layer contains needle-like scarlet dots or Black spots. The diseased fruit is eventually covered by the mold layer, the whole fruit becomes soft, and the internal pulp rots. High-temperature, high-humidity storage and transportation environment is suitable for the onset of disease. Germs can be spread through contact with diseased and healthy fruits and cause a large amount of decay.
4. Storage technology (1) Timely ripening period from November to March of the following year, mostly concentrated on the peels from January to March, greenish yellow, greenish yellow, and golden yellow; overharvesting results in soft flesh and lack of flavor. , quality decline. Due to inconsistent fruit maturity, harvesting should be carried out in batches, taking care not to damage the fruit during harvesting.
(2) Storage condition is between 0 and 3.3°C and relative humidity around 90%. In combination with wax coating or under film bag sealing conditions, Taiwanese jujube can be preserved for 30 to 40 days; if the temperature is lowered to (01)°C, the freshness will be maintained. Up to 70 days, good fruit rate of more than 90%. When transporting, it needs to be packed in perforated carton, 15 to 20 kilograms per carton, separated by shredding to avoid crushing each other. The transportation distance does not exceed 4 days, and the good fruit rate can reach 95%.
