Passion Fruit Farming Guide

Once the passion fruit has matured, it generally needs to be stored or transported to the markets. The tough outer skin makes transportation easier as it does not break easily. This also means that with the right conditions, passion fruits can be stored for a relatively longer duration of time.

For the purple passion fruits, the ideal stage for transportation to the markets is when the skins are still light purple in colour. This is the period when the passion fruit has begun to ripen but the skin is still relatively tough and unlikely to be compromised.

Know the Right Time to Harvest to Avoid Ruining the Flavour!

The respiration on the passion fruit during the ripening stage occurs when the passion fruit is still stuck on the vine. If you harvest the passion fruit earlier when the fruits are still green or just about to turn purple, it is going to have an unripe flavour and it is also not going to have the desired sweet natural aroma.

Generally, once the passion fruits have ripen, they can be harvested by lightly shaking off the vines and they will fall off easily on the ground. There are cases where farmers leave fully coloured passion fruit to abscise and fall on their own and be picked on the ground.

This is, however, not the ideal situation as it might lead to losses to the birds and some may even get spoilt if they are not picked just as they mature and are ripe. The passion fruit that is picked on the ground may have certain risks. It can have impact injury on the skin as well as scarring damage that may accelerate the rot. It will lead to rapid water loss in the passion fruit and there is a higher chance of it acquiring disease or fungal infections making it unfit for human consumption.

The Grading, Sizes and Packing of Your Passion Fruit Harvest

The ideal diameter for your purple passion fruits should 5cm to 8cm or 2 inches to 3 inches. For the yellow passion fruits, the ideal diameter should be 6cm to 8cm or 2.5 inches to 3 inches.

If the fruits are smaller in size, they should be classified under a lower grade and labelled so. Depending on the variety of the passion fruit, the ideal passion fruit skin colour should be full yellow or full purple. The skin colour for the hybrid passion fruit variety will vary.

Clean the Passion Fruit

Before storing your passion fruit, make sure that fruit is cleaned to get rid of dirt, surface stains or any adhering calyx as well as other tissue on the passion fruit skin surface.

Remove the dried calyx from the passion fruit as it is generally one of the main sources of decay of the passion fruit. For export or retail customers, the passion fruit is generally packed in 6Kg and 4.5Kg fibreboard cartons. There are cases when the passion fruit can be packed in one-layer or two-layer trays or cell packs.

In case the stem is attached to the passion fruit to the fruit, take extra care precaution so that the stem does not rub against the skin of the other passion fruits in the carton and cause bruising on the skin.

The Pre-Cooling Conditions for Passion Fruits

You can room cool or forced air cool at a temperature of 10 degrees Celsius.

Optimal Storage Conditions for Passion Fruits

Store your yellow passion fruits at a temperature of 7 degrees Celsius to 10 degrees Celsius or 45degrees Fahrenheit to 50 degrees Fahrenheit with a relative humidity of 90% to 95%. In this condition, the passion fruits can have a storage life of two weeks.

The purple passion fruits on the other hand are quite tolerant to chilled conditions and can thus be stored at temperatures of 3°C to 5°C or 37°F to 45°F for a duration of three to five weeks. So the purple passion fruits can stay fresh for close to two months when stored in the right conditions.

Controlled Packing Practices

There are techniques that farmers and retailers generally use to further extend the lifespan of the passion fruits. For example, film bagging and adding various coatings will significantly reduce water loss in the purple and yellow passion fruits.

Some retailers use a paraffin-based or a carnauba-based coating or even a wax coating on purple passion fruit before they are packed for storage or shipping. Doing this not only improves the passion fruit gloss which makes it more attractive to customers but it also helps in reducing the water loss in the passion fruit and also significantly extends the post-harvest life span of the passion fruit.

You can apply wax on the skin of the passion fruit it on the skin, applying the wax with a brush or simply rubbing it gently on the skin of the purple passion fruits.

Passion Fruit Retail and Display

On the shelves of the supermarkets, the passion fruits should be displayed at the room temperature. Avoid icing or misting the passion fruit on the display.
