Where is Gary Mount's apple farm?

Gary Mount, of Terhune Orchards in Princeton, New Jersey, started out with a strikingly similar cold storage system for the apples on his 200-acre farm: a room under the farm store, with a small natural spring running through it and a vent for warmer air. This kept the humidity high and the temperature low. Nowadays, Mount talks about his apple storage facility in a tone that borders on giddy – and with good reason. In 2010, he built what he calls his “dream apple storage” in a new barn. The barn houses refrigerated storage as well as one room of “controlled atmosphere storage” (“CA” for short).

Do apples live longer in the barrel?

For smaller producers, however, they see plenty of life in those old apples in the barrel. Far from loading their into the cellar for the winter, farmers – even small- and medium-scale ones – are increasingly using a wide range of technologies to extend the storage life of their apples and keep them in the market longer.

Is it better to store apples in the refrigerator or CA?

Regular refrigerated storage is good, but CA storage is better. Apples ‘breathe’ and controlled-atmosphere storage slows their breathing, which consequently slows their ripening. For a long time, Mount was advised against doing CA on a small scale and was told it wouldn’t be cost-effective.

How long can apples be stored in the refrigerator?

Specific storage conditions and practices not only ensure the quality of fruit but also limit cold-related injury or damage. Mature apples can typically be stored at 32-39°F, depending on the cultivar, for 6 months, but this can be extended to 12 months with close monitoring. If the apples are partially ripe, they can be kept in cold storage for 2-3 months, while fully ripened apples are limited to less than a month in cold storage. However, certain cultivars are chilling sensitive, meaning that they are damaged by exposure to low non-freezing temperatures for a certain amount of time. Chilling sensitivity may occur in Honeycrisp, Granny Smith, Gala, Fuji, Red Delicious, and Cortland apples and can be characterized by disorders such as soft scald (Figure 1), soggy breakdown (Figure 2), and lenticel breakdown among others. Recommended storage temperatures for apples with or without chilling sensitivity can be observed in Table 1.

How long to cool honeycrisp apples?

Delayed cooling or conditioning is the practice of temporarily exposing fruit to 50°F or 68°F for up to 7-10 days before cold storage. This practice is found to be helpful for the chilling sensitive cultivar Honeycrisp, as it decreases fruit susceptibility to chilling injury. There are reports indicating that a 7-day preconditioning period at 50°F dramatically reduced soft scald and soggy breakdown in Honeycrisp apples to be less than 1%, compared to control fruits. However, conditioning treatments have been frequently reported to exacerbate the incidence of bitter pit, another physiological disorder, induced in preharvest due to a nutritional imbalance, that results in small brown flesh lesions and also renders the fruit unmarketable. Bitter pit (Figure 3) is especially common in Honeycrisp apples, and is exacerbated by preconditioning treatments.

What temperature should peaches be stored at?

For peaches, on the other hand, storage life is much shorter than apples, thus they are much more vulnerable to spoilage. Peaches are ideally kept at 32°F, but a range of 29-34°F is acceptable, as shown in Table 2. However, if peaches are continuously stored in cold conditions of 36- 46°F for more than 2 weeks, the physiological disorder of chilling injury becomes a concern. Chilling injury is a physiological disorder caused by prolonged exposure to these temperatures of 36-46°F, but only appears after the ripening process continues at room temperature. It may manifest in peaches via symptoms such as flavor loss, flesh browning, flesh bleeding, flesh mealiness, leatheriness (Figure 4). Flesh bleeding is characterized by an accumulation of red pigments in the flesh, mostly around the peach pit. Mealiness occurs when peach flesh lacks juice, and can often lead to flesh browning. Leatheriness refers to patches in peach flesh that fail to ripen, therefore remaining dry and firm. As chilling injury is only expressed at room temperatures, all of these symptoms are apparent when the peaches reach customers, reducing marketability.

Why do we need cold storage?

Cold storage is an efficient way to maintain fruit quality, mitigate losses and maximize harvest potential. At ambient temperatures, fruit quality characteristics are rapidly changing, decreasing storability. Specifically, long-term ambient storage conditions lead to changes in color, texture, flavor (soluble solids, acidity, aroma), and nutritional value. Therefore, cold storage is a key solution to slow down these changes and thus maintain quality for longer periods of time.

Why is cold storage important?

Additionally, fruit can be sold year-round, regardless of the growing season. Both of these advantages signal increased profitability for the industry. Fruit appearance heavily influences purchasing decisions. Cold storage ensures that the appearance—a presumed indicator of freshness, crispness, and sweetness—is maintained.

How long can you keep peaches after packing?

Postharvest preconditioning can be employed by storing peach at 68°F for 1 to 2 days after packing, but prior to cold storage at 32°F. Packing the fruit at cold temperature prevents additional damage, while the warming period allows gentle ripening to prevent chilling injury. Postharvest intermittent warming involves immediate storage at 32°F, with one day of storage at 68°F every 10 to 14 days. This technique ensures gradual ripening throughout the cold storage period.

What does an apple cell produce?

Apple cells produce ethylene and contain ethylene receptors — and not just cells in the skin, but those inside too. When an ethylene molecule latches onto an ethylene receptor, it kicks off a cascade of reactions inside the cell to ripen the fruit.

Why do apples need oxygen?

Like us, apples need oxygen to carry out their metabolic functions, including ripening. Less oxygen means all those processes taper off, regardless of the amount of ethylene present. But there is a limit to how much you can starve an apple of oxygen.

Why does an apple absorb light?

If an apple is getting stressed because it's not getting enough oxygen, its green pigment called chlorophyll absorbs and re-emits light in a different way to when the apple is healthy.

How to keep apples fresh?

Bill Suhr, the owner of the sustainable farm Champlain Orchards in Shoreham, Vermont, says he uses Smartfresh, an ethylene blocker, to extend the shelf life of apples on his orchard. Ethylene is a natural gas that apples naturally produce as it starts to ripen—the blocker slows down that process, essentially stunting its growth. He also uses storage rooms with controlled atmospheres to delay decay and keep apples fresh for as long as possible. " We sell fruit year round so some fruit that is locked up in CA storage in September could be sold 'fresh' the following August," Suhr explains.

What is the best way to protect apples from bugs?

The fungicides protect the apples from bad bacteria, and the pesticides protect them from insects and other pests (since, as Fourmuzis says, they naturally attract bugs). Some producers also add a food-grade wax made of fatty acids and long-chain alcohols.

Do apples have wax coats?

If you're still weirded out, one tip is to go for organic apples that don't have a wax coat, which Formuzis says is the main tool farmers use to allow apples to last months in cold storage.
