냉장 보관을 사용하여 과일과 야채를 보관하는 것은 과학적인 신선도 유지 방법입니다., 영양분과 수분을 더 잘 유지할 수 있는.
첫 번째, 우리는 이야기 과일 냉장 보관, 그것은 가지고있다 3 유형: 신선한 냉장 보관, 통제된 분위기 (캘리포니아) 냉장, 및 폭발 냉동고 냉장 보관.
과일 신선 온도 및 보관 시간
신선한 온도
For room chiller temperature, fresh cold storage and CA cold storage are roughly the same, is -2~+5°C. 일부 열대 과일 (바나나와 같은, 망고, 등) are kept the temperature above +10°C.
송풍 냉동고 냉장 보관의 온도가 가장 낮습니다., -18°C 정도.

Fruit Storage Tips
1). 과일을 냉장 보관하기 전에 미리 식히십시오.
사전 냉각은 수확 후 과일의 호흡 및 증산을 억제할 수 있습니다., 동시에 과일이 저온 저장의 저온 환경에 더 잘 적응하도록 돕습니다..
알아채다: Vegetable also need pre-cool.
2). 냉장 보관 온도를 안정적으로 유지
Temperature difference should be stable: ±1°C. 온도가 너무 높으면, 과일의 호흡 강도가 상승합니다, 결과적으로 후숙. 너무 낮은 온도는 과일에 동상을 일으킬 수 있습니다..
3). 습도를 안정적으로 유지
Keep the fresh cold storage humidity stable: 75~90%.
과도한 습도는 쉽게 결로 및 과일의 변질을 유발할 수 있습니다.. Too low humidity will cause fruits to lose water and dry up, 먹을 수 있는 가치를 잃고.
4). 다른 과일을 섞지 마십시오
열대 과일은 온대 및 한랭지 과일과 섞일 수 없습니다..
Excessive temperature differences will cause fruits freezing damage in temperate and frigid zones.
그 동안에, 고온은 또한 곰팡이 및 기타 박테리아의 성장과 번식을 가속화합니다., 박테리아에 감염된 과일의 썩음과 변질을 초래합니다..
습도는 과일 저장에 매우 중요합니다.. 과일을 냉장 보관할 때, 실내 습도가 다양한 습도 요구 사항을 충족할 수 없음.
바나나와 같은 일부 과일, 감, 사과, 키위, 및 기타 갱년기 과일은 익을 때 에틸렌을 방출합니다.. 에틸렌은 과일 숙성을 촉진하는 식물 호르몬입니다.. When fruits mixed, will lead to accelerated ripening of other fruit.
야채 냉장 보관 온도
The temperature of vegetable cold storage is roughly 0~+15°C, 미생물의 활동을 억제할 수 있는 온도, 채소의 부패율 감소, 야채의 저장 시간을 연장.

Adjust Tomato Storage Temperature by Ripeness Stage
Why we talk tomato storage separately? Because tomatoes are relatively sensitive to low temperatures, they shouldn’t place directly in overly cold storage conditions, especially before they are fully ripe.
The recommended tomatoes’ storage temperature isn’t a single fixed point; it should adjust according to their ripeness stage. 일반적으로, the most suitable storage range for tomatoes is 12–14°C, with relative humidity around 85%, and prolonged exposure to temperatures below 8°C is forbidden under any circumstances.
Mature green tomatoes: Store them mainly for ripening, and keep them in a milder environment so they can retain their ability to ripen normally instead of exposing them to low-temperature refrigeration.
Turning tomatoes: Store them in conditions that allow them to continue ripening while still providing short-term preservation, and avoid excessively low temperatures that cause uneven color development and poor flavor.
Red-ripe tomatoes: Store them to slow down over-ripening, using short-term refrigeration only, and bring them back to room temperature before use to reduce the negative effects of low temperatures on texture and aroma.
Problems caused by low-temperature storage in tomatoes
When tomatoes store at excessively low temperatures, the most common issue isn’t freezing damage, but chilling injury.
Chilling injury includes:
-
Failure to ripen normally, with green fruit remaining difficult to turn red even after extended storage.
-
Loss of aroma, causing the characteristic tomato flavor to become weak or bland.
-
Softened flesh and poorer texture, with undesirable internal tissue condition after cutting.
-
Physiological disorders on the skin or surface, such as pitting, sunken areas, or abnormal spotting.
-
Quality problems becoming more obvious after removal from storage. 많은 경우에, the fruit may appear “spoiled,” but the damage is actually the result of accumulated chilling injury during earlier low-temperature storage.
Additional notes:
-
Unripe tomatoes shouldn’t be refrigerated directly, because this can interfere with the normal ripening process.
-
Tomatoes are highly sensitive to ethylene, so they should store separately from strong ethylene-producing fruits and vegetables, such as apples, pears, 복숭아, and nectarines.
-
Ripe tomatoes may be refrigerated for a short period, but they are better suited to short turnover and aren’t suitable for long-term storage.
-
For commercial storage, ripeness grading is very important, because mature green, 파쇄기, and red-ripe tomatoes have different storage objectives and therefore require different temperature strategies.
List of Fruits and Vegetables Unfit to Store in Standard Cold Rooms
Below is the list of fruits and vegerables which can’t store long-term in 0–4°C standard cold rooms:
| Produce | 이유 | 노트 |
|---|---|---|
| Potato | Low temperatures accelerate the conversion of starch to sugars, leading to an overly sweet taste, excessive browning during frying/baking. | Store at about 7–10°C in a cool, 마른, dark place; avoid high humidity and very low temperatures in cold rooms. |
| 고구마 | At 0–4°C they easily develop chilling injury: sunken skin, internal darkening, hard or fibrous texture, 등 | Prefer 13–16°C with relatively high humidity and good ventilation; use curing plus warm storage rather than standard cold rooms. |
| Dry onion | High humidity in cold rooms promotes mold, softening, and sprouting; the dry outer skins lose their protective effect and shorten storage life. | Store at 7–13°C in a low‑humidity, well‑ventilated environment, using mesh bags or ventilated containers. |
| 마늘, shallot | Low temperature and high humidity cause sprouting, decay, and mold, and also affect flavor and appearance. | Store at cool, dry room temperature with good air movement; keep separate from potatoes to avoid mutual moisture problems. |
| 바나나 | Suffer chilling injury even with short exposure below about 13°C: the peel turns gray or black, the flesh becomes firm and off‑flavor, and normal ripening is disrupted. | Store green bananas around 13–14°C; avoid 0–4°C cold rooms during storage and ripening. |
| 망고 | At 0–4°C they show peel browning, water‑soaked patches, and serious flavor loss. | Store at about 10–13°C with appropriate ripening management instead of near 0°C cold storage. |
| Papaya | Low‑temperature storage causes chilling injury of peel and flesh, dull color, poor texture, and weak aroma. | Prefer storage around 10–13°C in a high temp cold room. |
| 오이 | Develop water‑soaked spots, pitting, and softening near 0°C, with obvious quality and appearance loss. | Best kept at 7–10°C and high relative humidity; avoid long‑term storage with 0–2°C commodities. |
| Eggplant | At 0–4°C they are prone to chilling injury, including skin browning, spotting, softening, and internal discoloration. | Store around 8–10°C, especially for long‑distance transport or longer storage time. |
| Sweet pepper | Very low temperatures cause surface pitting, internal darkening, water loss, and reduce crispness and gloss. | Store at 7–10°C with relatively high humidity to slow dehydration. |
| Citrus | Long time storage near 0°C can lead to chilling injury, peel browning, flavor loss. | Store in zones at 4–8°C, depending on the variety. |
| 겨울 멜론 | Performs better in cool, 마른, well‑ventilated ambient conditions; low‑temperature, high‑humidity cold rooms tend to cause rot and mold. | Store at cool room temperature with good ventilation. |
How to Divide One Cold Room into Multiple Temperature Zones?
Divide one cold room into 3 main temperature zones, with each zone further subdivided by ethylene/humidity needs. This is the most common practical zoning approach for commercial cold storage, covering over 90% of fruits and vegetables storage requirements.
1. Low-temperature zone (0–2°C, high humidity 90–98%)
Suitable products: Leafy greens, brassica vegetables (such as broccoli, cauliflower, cabbage), root vegetables (such as carrots, European radishes), temperate berries, and some strawberries—products that tolerate low temperatures well.
위치: Near the back wall or coldest end of the cold room, close to the evaporator air outlet. This leverages the natural settling of cold air, providing the lowest temperature and highest humidity, ideal for products that “fear heat but not cold.”
Operation tips:
1. Prioritize ethylene‑sensitive vegetables (such as lettuce, broccoli) and keep them away from any fruit zones.
2. Use tall racks or independent pallet racks for isolation to prevent temperature crossover with the mid‑temperature zone.
3. 습도 조절: Use misting humidification or high‑humidity packaging to ensure it stays above 90% RH.
2. Mid-temperature zone (5–10°C, medium‑high humidity 85–95%)
Suitable products: Certain fruit vegetables (such as cucumbers, eggplants, peppers, bell peppers, immature tomatoes), some citrus fruits, transitional tropical/subtropical fruits (such as mangoes after precooling), and some root vegetables.
위치: Middle of the cold room, slightly closer to the door, where temperature is relatively stable with minimal fluctuations. This avoids the “overcooling” of the low‑temperature zone and the “rewarming” effects of the high‑temperature zone, making it suitable for chilling‑sensitive products that still need preservation.
Operation tips:
1. This zone often serves as a “transitional area” for short‑term storage (7–14 일) of chilling‑sensitive fruits and vegetables.
2. 에틸렌 관리: Avoid sharing space with high ethylene producers like apples or bananas; if mixing is unavoidable, use plastic partition curtains or separate racks.
3. Rack design: Leave space under the bottom shelves to ensure air circulation and prevent cold air pooling at the base.
3. High‑temperature sensitive zone (10–15°C, medium humidity 80–90%)
Suitable products: Tropical fruits (such as bananas, mangoes, papayas, pineapples), ripe tomatoes, potatoes, 고구마, dry onions and garlic, winter melons, and hard‑shell squashes—highly chilling‑sensitive or dry‑type products.
위치: Near the entrance door or warmest end of the cold room, utilizing door opening rewarming and equipment heat radiation.
This area naturally has higher temperatures, suitable for fine‑tuning with small electric heating wires or PTC heaters to reach the target temperature.
Operation tips:
1. Provide independent ventilation to prevent cold air infiltration from the low‑temperature zone.
2. Lower humidity control: Use dehumidifiers or dry packaging to prevent mold; place dry onions and potatoes on ventilated mesh racks.
3. Often used as a “ripening + short‑term preservation” zone, where bananas and mangoes can complete ethylene ripening and go directly to sale.
What Cold Room Solution Do You Need for 3/7/30 Days or 6 개월?
Quick decision guide:
3 날: Choose a standard cold room; prioritize quick cooling and easy product turnover.
7 날: Choose a standard cold room with better humidity and airflow control.
30 날: Choose a well-designed standard cold room, or split products by temperature zone if you store mixed produce.
6 개월: Choose CA cold storage for suitable high-value products; standard cold rooms often can’t maintain the same quality for long-term storage.
결론
냉장 보관은 과일과 채소를 신선하게 유지하는 최상의 솔루션입니다., 편리하고 경제적입니다, but you should understand different fruits and vegetables should store in different types cold storages with different chiller room temperature.
