Cantaloupe Recommendations for Maintaining Postharvest Quality. A quick guide to harvesting and storing melons, squash, and pumpkins. September 02, Some ripening basics Fruit and vegetables are typically assigned to two categories that define their ripening behaviors: Climacteric: Climacteric fruits and vegetables continue to ripen off the vine. They experience a rapid increase in respiration during ripening. They also often produce a hormone called ethylene after harvest, which can speed up ripening and senescence.

If eaten at an immature stage, these fruits and vegetables taste bland, and the texture is often not as soft as it is meant to be. If left at room temperature they will become sweeter. Common examples of climacteric fruit include apples, bananas, peaches, and tomatoes.

Non-climacteric: These fruits and vegetables do not continue to ripen off the vine. Once removed, the sugar content will not increase, and so picking at exactly the right time is important for flavor.

These fruits and vegetables can still go bad if left out, but they tend to have a longer shelf life than climacteric fruits and vegetables.

Examples include: grapes, strawberries, and watermelon. Many online articles tell you to harvest at full slip, but there are two problems with this: Many cucurbits, including watermelon, honeydew melons, squash, and pumpkins, never actually develop an abscission layer. Watermelons Watermelons all belong to the same species, Citrullus lanatus. This information tells you which fruits will ripen and improve after picking and those that will not. When fruit is ripe it has maximum sweetness and flavor.

And the more we know about how and when our favorite fruits mature and ripen, the better harvesting and shopping decisions we can make. A sour orange is not going to suddenly sweeten off the tree. But a mature, firm plum can gradually morph into perfection after a few days on the counter. One helpful tip when growing your own food is to understand the importance of maturity as a plant milestone.

Mature does not mean ripe. Remember to only refrigerate bananas once they are ripe. Occasionally this discolouration can happen to our bananas on very cold delivery days, although we do our utmost to keep them warm by wrapping them in blankets — exposure to extreme cold even for a short period, may turn the bananas dark grey in colour.

To keep a bunch of bananas fresh for longer, wrap the stems in some plastic wrap. Re-cover the bananas with the wrap after removing one. This method prevents ethylene gas, produced naturally in the ripening process, from reaching other parts of the fruit and prematurely ripening it.

Store unripe fruit and veg like pears, peaches, plums, kiwis, mangoes, apricots, avocados, melons, and bananas in a basket or bowl on a clean dry surface. Fruits and vegetables stored at room temperature should be removed from any packaging and left as loose as possible. Some items, like apricots and avocados, will ripen faster in a paper bag left out on the side! Once ripe, you can store fruit and veg in the fridge — although it is wise to them apart in the fridge as ethylene gas will continue to ripen the fruit.

Keep potatoes, onions, and tomatoes in a cool, dry place, but not in the fridge. You can also use a breathable cotton cloth bag. But do not use plastic or any material that seals in moisture.

Go for 3 to 5 days. No problem, just put the unripe fruit s by itself into a paper bag. The fruit is going to begin to ripen anyway, and in so doing is going to give off ethylene.
