Cold Room Temperature Chart by Product: Storage Temperature and Humidity Guide

Different products cannot simply be placed in the same cold room at one standard setting. Fresh meat and fish may need temperatures close to 0°C, but those conditions can damage bananas, mangoes and ripe tomatoes.

Humidity matters too. Leafy vegetables can wilt when the air is too dry, while onions, chocolate and dry ingredients need much less moisture. Medicines are another case entirely, as their approved storage instructions must always be followed.

The cold room temperature chart below brings these requirements together in one place. It covers recommended temperature and humidity ranges, typical storage periods, common risks and products that are better kept apart.

Quick answer: Cold room settings vary by product. Many chilled foods are kept at 5°C or below, and frozen goods at −18°C or colder. But the right setting may change with the product’s condition, packaging and expected storage time.

Cold Room Temperature Chart: Quick Reference

Product category	Typical temperature	Typical humidity	Important note
Fresh meat	−1°C to 2°C	85–90% RH	Keep below ready-to-eat food

Fresh fish	0°C to 2°C	95–99% RH when iced	Very short storage life
Dairy products	0°C to 4°C	Product-dependent	Keep away from strong odours
Shell eggs	7°C or colder	70–80% RH	Avoid condensation and temperature cycling
Frozen food	−18°C or colder	Not applicable	Avoid thawing and refreezing
Leafy vegetables	0°C to 1°C	95–100% RH	Keep away from ethylene-producing fruit
Bananas	13°C to 14°C	85–95% RH	Chilling injury can occur below about 13°C
Mangoes	10°C to 13°C	85–90% RH	Do not place in a normal 0–4°C chiller
Ripe tomatoes	10°C to 13°C	85–90% RH	Chilling-sensitive and ethylene-producing
Apples	−1°C to 4°C	90–95% RH	Strong ethylene producer

Chocolate	15°C to 18°C	Below 50–55% RH	Store cool and dry, not in a normal refrigerator
Ice cream	−18°C to −25°C	Not applicable	Stable temperature helps prevent ice crystals

These are commercial storage targets rather than guarantees of shelf life. Product condition, initial quality, packaging, airflow, sanitation and temperature history all affect how long stock can be stored.

Meat and Poultry Storage Temperature Chart

Fresh meat should be kept close to its freezing point without being allowed to freeze unintentionally. A room temperature of 4°C may satisfy general chilled-storage requirements, but a lower and more stable range is usually preferred for commercial meat storage.

Product	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Beef	Fresh or chilled	−1°C to 2°C / 30–36°F	85–90%	1–3 weeks; vacuum-packed products may last longer	Bacterial growth, drying and drip loss
Lamb or mutton	Fresh or chilled	−1°C to 2°C / 30–36°F	85–90%	1–2 weeks	Spoilage and surface dehydration
Chicken and poultry	Fresh or chilled	0°C to 2°C / 32–36°F	85–90%	A few days to about one week	Rapid spoilage and raw-poultry contamination
Processed meat	Cooked or cured, chilled	0°C to 4°C / 32–39°F	80–85%	Follow the label	Listeria risk, drying and odour transfer
Frozen meat	Fully frozen	−18°C or colder / 0°F or below	Not applicable	Several months	Freezer burn, oxidation and thaw–refreeze damage

Raw meat and poultry should be stored below cooked and ready-to-eat products. This prevents raw juices from dripping onto food that will not receive further cooking.

Different raw meats may share a correctly managed room, but they should still be separated by shelving, containers or designated storage areas.

Fish and Seafood Storage Temperature Chart

Fresh seafood deteriorates faster than most meat. It should arrive cold, be placed into storage quickly and remain surrounded by suitable ice or held in a properly designed fish chiller.

Product	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Lean or white fish	Fresh, stored on ice	0°C to 2°C / 32–36°F	95–99% when iced	1–3 days	Rapid spoilage, odour and temperature abuse
Fatty fish	Fresh, stored on ice	0°C to 2°C / 32–36°F	95–99%	1–2 days	Rancidity and histamine risk in susceptible species
Live shellfish	Live and chilled	2°C to 7°C / 36–45°F	High humidity; do not immerse in fresh water	Usually 1–2 days	Mortality, contamination and poor ventilation
Frozen seafood	Fully frozen	−18°C or colder / 0°F or below	Not applicable	Several months	Freezer burn and texture loss

Fish should generally be separated from dairy products, butter, eggs, chocolate, mushrooms and other items that readily absorb odours.

Live shellfish need product-specific handling. They must remain alive, ventilated and protected from fresh water or conditions that cause them to suffocate.

Dairy Products and Egg Storage Chart

Dairy products usually perform well in a clean 0–4°C cold room. Packaging and odour control are important because milk, butter and some cheeses can absorb smells from nearby food.

Product	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Milk	Pasteurised and sealed	0°C to 4°C / 32–39°F	Not normally controlled for sealed packs	Follow the label	Spoilage and odour absorption
Cheese	Hard or soft	2°C to 8°C / 36–46°F	About 65–80%, depending on variety	Weeks to months	Mould, drying and odour transfer
Butter	Chilled	0°C to 4°C / 32–39°F	Not normally controlled for sealed packs	Weeks; longer when frozen	Rancidity and odour absorption
Yogurt	Chilled	2°C to 4°C / 36–39°F	Not applicable for sealed packs	Follow the label	Spoilage and quality deterioration
Shell eggs	Chilled	7°C or colder / 45°F or below	70–80%	Several weeks	Condensation, moisture loss and contamination

Eggs should be kept at a stable temperature. Moving cold eggs repeatedly into warm, humid air can create condensation on the shell and increase contamination risk.

Vegetable Cold Room Temperature and Humidity Chart

Vegetables do not all belong in the same room. Leafy vegetables need cold, humid conditions, while onions require lower humidity and tomatoes and cucumbers can suffer chilling injury in a standard cold room.

Vegetable	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Leafy greens	Lettuce, spinach and similar produce	0°C to 1°C / 32–34°F	95–100%	1–3 weeks	Wilting, decay and ethylene damage
Root vegetables	Beets, turnips and similar produce	0°C to 2°C / 32–36°F	95–100%	Weeks to months	Drying and sprouting
Potatoes	Table stock	4°C to 10°C / 40–50°F	90–95%	Weeks to months	Cold sweetening, greening and sprouting
Dry onions	Properly cured	0°C to 5°C / 32–41°F	65–70%	Several months	Sprouting, rot and odour transfer
Ripe tomatoes	Ready for distribution	10°C to 13°C / 50–55°F	85–90%	1–2 weeks	Chilling injury below about 10°C
Mature-green tomatoes	Held for ripening	13°C to 21°C / 55–70°F	85–90%	Depends on ripening stage	Failure to ripen when stored too cold
Cucumbers	Fresh	10°C to 12°C / 50–54°F	85–95%	About 10–14 days	Chilling injury, pitting and ethylene damage
Bell peppers	Fresh	7°C to 10°C / 45–50°F	90–95%	2–3 weeks	Chilling pitting below about 7°C
Broccoli	Fresh	0°C to 1°C / 32–34°F	95–100%	About 10–14 days	Yellowing and ethylene exposure
Cauliflower	Fresh	0°C to 1°C / 32–34°F	95–98%	2–4 weeks	Browning and ethylene exposure
Carrots	Topped	0°C to 1°C / 32–34°F	95–100%	Up to several months	Drying and ethylene-related bitterness
Mushrooms	Fresh	0°C to 2°C / 32–36°F	90–95%	About 5–7 days	Browning, sliminess and odour absorption
Fresh herbs	Most varieties	0°C to 2°C / 32–36°F	95–100%	About 1–2 weeks	Wilting and decay
Basil	Fresh	10°C to 12°C / 50–54°F	High humidity	Product-dependent	Chilling injury below about 10°C

Why onions and leafy vegetables should not share a room

Leafy vegetables commonly need 95–100% relative humidity. Dry onions need approximately 65–70% RH.

Setting the room for leafy vegetables can encourage onion rot and sprouting. Setting it for onions will cause leafy vegetables to lose water and wilt. Separate rooms or independently controlled storage zones are therefore preferable.

Fruit Cold Room Temperature and Humidity Chart

Fruit storage depends heavily on variety, ripeness and whether the product is intended for ripening, short-term distribution or long-term storage.

Fruit	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Apples	Fresh	−1°C to 4°C / 30–39°F	90–95%	Several months in suitable commercial storage	Ethylene production and storage scald
Bananas	Green or ripening	13°C to 14°C / 55–58°F	85–95%	About 1–2 weeks	Blackening and chilling injury below about 13°C
Mangoes	Fresh	10°C to 13°C / 50–55°F	85–90%	About 2–3 weeks	Chilling injury below about 10°C
Oranges and citrus	Fresh	3°C to 9°C / 37–48°F	85–90%	Several weeks	Rind drying and variety-dependent chilling injury
Grapes	Fresh	−1°C to 0°C / 30–32°F	90–95%	Weeks to months	Freezing, berry shatter and mould
Berries	Strawberries, blueberries or raspberries	0°C to 1°C / 32–34°F	90–95%	A few days to about one week	Mould and rapid softening
Dates	Fresh or semi-dry	0°C to 4°C / 32–39°F	70–75%	Several months; longer when frozen	Sugaring, fermentation, insects and excess moisture
Avocados	Ripe	4°C to 7°C / 40–45°F	85–90%	About 1–2 weeks	Chilling injury and uneven ripening
Avocados	Unripe	7°C to 13°C / 45–55°F	85–90%	Variety-dependent	Chilling injury and ripening control
Pineapples	Fresh	7°C to 13°C / 45–55°F	85–90%	About 1–2 weeks	Internal browning and chilling injury
Watermelons	Whole	10°C to 15°C / 50–59°F	85–90%	About 2–3 weeks	Pitting and chilling injury below about 10°C
Cut fruit	Fresh-cut and ready to eat	0°C to 4°C / 32–39°F	Controlled through packaging	Usually 1–3 days	Rapid microbial growth and contamination

Cut fruit is no longer protected by its skin. It should be treated as ready-to-eat chilled food and stored above raw meat, poultry and seafood.

Which Fruits and Vegetables Produce Ethylene?

Ethylene is a natural plant hormone that speeds ripening and ageing. Problems arise when strong ethylene producers are stored beside sensitive vegetables or flowers.

Common ethylene-producing products

• Apples
• Bananas
• Tomatoes
• Mangoes
• Avocados
• Melons

Common ethylene-sensitive products

• Lettuce and leafy greens
• Broccoli
• Cauliflower
• Carrots
• Cucumbers
• Cut flowers

Ethylene-producing fruit should not share an enclosed cold room with sensitive products unless the room has suitable ventilation, gas management and product separation.

Flower Cold Room Temperature and Humidity Chart

Flower storage is not the same as fruit and vegetable storage. Most cut flowers need high humidity, gentle airflow and protection from ethylene.

Flower type	Condition	Temperature	RH	Typical commercial duration	Main storage concern
Temperate cut flowers	General mixed flowers	0°C to 2°C / 32–36°F	90–95%	Several days to about two weeks	Dehydration, Botrytis and ethylene damage
Roses	Cut	0°C to 2°C / 32–36°F	90–95%	Up to about two weeks	Bent neck, mould and ethylene exposure
Tropical flowers	Orchids, anthurium and heliconia	7°C to 15°C / 45–59°F	90–95%	Several days to about one week	Chilling injury and blackening

Tropical flowers should not be kept at the same temperature as roses and other temperate flowers. They can develop visible cold damage even though the cold room is operating correctly for the temperature stock.

Flowers should also be kept away from apples, bananas, tomatoes and other ethylene-producing produce.

Medicine and Pharmaceutical Storage Temperature Chart

Pharmaceutical storage must always follow the approved product label, registered stability data and manufacturer instructions. A general chart must never replace product-specific requirements.

Product	Condition	Temperature	RH	Storage period	Main storage concern
Most refrigerated vaccines	Unopened and refrigerated	2°C to 8°C / 36–46°F	Follow product requirements	Until approved expiry when correctly stored	Heat exposure and irreversible freeze damage
Insulin	Unopened	2°C to 8°C / 36–46°F	Follow the specific product label	Product-specific	Freezing and loss of potency from excessive heat
Refrigerated medicines	As stated on the label	Commonly 2°C to 8°C / 36–46°F	Product-specific	Follow the label	Product-specific temperature sensitivity
Controlled-room-temperature medicines	As stated on the label	Commonly 20°C to 25°C / 68–77°F	Product-specific	Follow the label	UAE heat and humidity exposure

Important pharmaceutical storage rules

• Do not give one storage temperature for all medicines.
• The approved label always takes priority over a general temperature chart.
• Many refrigerated vaccines and insulin products are damaged by freezing.
• Damage caused by freezing may not be visible.
• Pharmaceutical products should not be stored with food.
• Refrigerated medicines require dedicated, monitored equipment.
• Temperature alarms, data logging, calibration and thermal mapping may be required depending on the operation and regulatory framework.
• Any temperature excursion should be documented and assessed using the manufacturer’s stability information.

Some vaccines and biological products require frozen or ultra-cold conditions. These are exceptions and must be handled strictly according to their individual instructions.

Chocolate, Bakery and Speciality Product Storage Chart

Not every temperature-controlled product belongs in a refrigerator or freezer.

Product	Condition	Temperature	RH	Typical duration	Main storage concern
Chocolate	Finished product	15°C to 18°C / 59–64°F	Below 50–55%	Several months; varies by type	Fat bloom, sugar bloom, condensation and odour
Flour and sugar	Dry ingredients	10°C to 21°C / 50–70°F	Below 60%	Several months	Moisture, caking and pests
Fresh compressed yeast	Chilled	0°C to 4°C / 32–39°F	Not normally controlled for sealed packs	Product-dependent	Loss of activity when warm
General frozen food	Fully frozen	−18°C or colder / 0°F or below	Not applicable	Several months	Freezer burn and thaw–refreeze damage
Ice cream	Frozen	−18°C to −25°C / −13–0°F	Not applicable	Several months	Heat shock and formation of large ice crystals
Soft drinks	Chilled for sale	2°C to 7°C / 36–45°F	Not applicable	Follow the label	Freezing and container damage
Bottled water	Sealed	Cool ambient or chilled	Not applicable	Follow the label	Heat, sunlight and odour exposure
Seeds	Cool and dry	0°C to 10°C / 32–50°F	Commonly below 40%	Months to years	Loss of viability from heat and moisture
Shelled nuts	Chilled or cool	0°C to 4°C / 32–39°F	Around 55–65%	Several months	Rancidity, pests and odour absorption
Rice, pasta and canned food	Temperature-controlled dry store	10°C to 21°C / 50–70°F	Below 60%	Product-dependent	Moisture, pests and accelerated deterioration

Some values in this section are broad commercial guidance. Product packaging, supplier instructions and label requirements should be checked before finalising the room setting.

Should chocolate be stored in a cold room?

Chocolate can be kept in temperature-controlled storage, but a standard 0–4°C cold room is usually too cold. A dry room at around 15–18°C is a better fit.

The real trouble often starts when very cold chocolate is taken into warm, humid UAE air. Moisture can settle on the surface, leaving pale marks, a rough finish or damp packaging. Chocolate also picks up nearby smells quite easily, so it should be kept away from strongly scented products.

Frozen and Deep-Frozen Storage

The normal commercial target for frozen food is:

−18°C or colder

This applies to frozen meat, seafood and general frozen products. Relative humidity is not normally used as the main control value in a room operating below −18°C.

Ice cream is often held at a lower and more stable temperature, such as −18°C to −25°C, because small temperature changes can soften the product and create large ice crystals.

A colder freezer setting cannot compensate for poor packaging, repeated door opening or products that have partially thawed.

Can Different Products Share One Cold Room?

Sharing a cold room is only practical when products have compatible temperature, humidity, hygiene, airflow and odour requirements.

Product group	Products normally requiring separation
Raw meat, poultry and fish	Ready-to-eat food, dairy, flowers, medicines, chocolate and dry goods
Dairy and eggs	Fish, onions, chemicals and strong-smelling cheese
Leafy vegetables	Apples, bananas, tomatoes and other strong ethylene producers
Tropical produce	Meat, dairy and leafy vegetables stored at 0–4°C
Apples and ripening fruit	Ethylene-sensitive vegetables and flowers
Temperate flowers	Fruit, vegetables and tropical flowers require warmer storage
Pharmaceuticals	All food, flowers, chemicals and general commercial stock
Chocolate and dry goods	High-humidity produce, fish, onions and chemicals

The main reasons products cannot share a room

Temperature mismatch

A room set at 1°C may suit fish, leafy vegetables and roses, but it can damage bananas, mangoes, ripe tomatoes, cucumbers and tropical flowers.

Humidity mismatch

Leafy vegetables need close to saturated air. Onions, chocolate, seeds and dry ingredients require much drier conditions.

Ethylene exposure

Ripening fruit can shorten the life of vegetables and flowers, even when the room temperature is correct.

Odour transfer

Fish, onions, cheese and chemicals can taint milk, butter, eggs, chocolate and produce.

Cross-contamination

Raw meat, poultry and fish must not be stored above ready-to-eat food. Leakage or dripping can contaminate products that will not be cooked again.

Regulatory separation

Medicines and vaccines need dedicated and appropriately monitored pharmaceutical storage. They should never be placed in a general food cold room.

Storage Temperature Is Not the Same as Product Temperature

A cold room thermostat measures air temperature. It does not necessarily show the temperature at the centre of the product.

For example, a delivery of warm meat or cooked food may enter a room operating at 2°C. The room air can return to 2°C while the centre of the product remains much warmer.

This difference matters because:

• Warm stock adds a large refrigeration load.
• Densely packed pallets cool slowly.
• Blocked airflow creates warm spots.
• Door opening changes air temperature quickly.
• Product core temperature changes more slowly.
• Food inspections may use a calibrated probe to check the product itself.

A storage cold room is also not a substitute for a blast chiller. Hot cooked food should be cooled using a process designed to move it quickly through the temperature danger zone before it enters normal chilled storage.

What Does Relative Humidity Mean in a Cold Room?

A cold room can be at the right temperature and still be wrong for the product inside. The missing part is often moisture in the air.

Take leafy vegetables as an example. In dry air, they lose water, soften and start to wilt. Raise the humidity too far, though, and water may collect on the product, packaging, walls or floor. That creates a different set of problems, including mould, rot and slippery surfaces.

Not every product needs moist air. Chocolate, onions and dry ingredients are usually better kept in drier conditions. Fresh produce and flowers generally need more humidity to hold their weight and appearance.

Packaging changes things as well. It can slow moisture loss, but it may trap droplets when warm stock enters a cold room or when the temperature moves up and down.

So, when planning storage, do not look at the temperature setting alone. Check how much moisture the product needs, how it is packed and whether condensation is likely to form.

Cold Room Temperature Planning for the UAE Climate

A cold room in Dubai, Abu Dhabi, Sharjah or another UAE location must handle conditions that are very different from those in a mild climate.

High outdoor temperature

UAE summer temperatures can exceed 45°C. The refrigeration system must remove both the product load and the heat entering through panels, doors, floors and ceilings.

Equipment selected for a lower outdoor design temperature may run continuously and struggle to recover after loading.

Humid outside air

Hot, humid air enters whenever a cold room door opens. As it cools, moisture can condense on surfaces or freeze on the evaporator.

This may lead to:

• Wet floors
• Ice around doors
• Frosted evaporator coils
• Mould growth
• Damaged packaging
• Higher defrost demand
• Temperature instability

Warm incoming products

Products arriving warm may represent a larger cooling load than the room structure itself. The refrigeration capacity must be based on the incoming product temperature, daily quantity and required cooling time.

Frequent door opening

Busy kitchens, supermarkets and distribution centres may open the cold room door many times per hour. Strip curtains, suitable doors, controlled loading procedures and correct evaporator selection help reduce heat and moisture entry.

Dust on condenser coils

Dust and airborne sand can collect on condenser coils. A dirty condenser cannot release heat efficiently, so the compressor runs hotter and uses more power.

Cleaning frequency should reflect actual UAE site conditions rather than relying only on a generic maintenance interval.

Poor airflow

Stock should not block the evaporator or be packed tightly against walls and ceilings. Restricted airflow creates warm areas that may not appear on the room thermostat.

Monitoring and alarms

Commercial cold rooms should use calibrated temperature monitoring appropriate to the stored product. Pharmaceutical rooms and higher-risk operations may require continuous logging, alarms, backup systems and mapped sensor positions.

How to Select the Right Cold Room Setting

Before selecting a temperature, confirm:

1. What exact product will be stored?
2. Is it fresh, frozen, ripe, unripe, cooked or ready to eat?
3. What is its temperature when it enters the room?
4. How much product enters each day?
5. How long will it be stored?
6. What relative humidity does it need?
7. Does it produce or react to ethylene?
8. Can it absorb or release strong odours?
9. Does it need dedicated hygienic or pharmaceutical storage?
10. How frequently will the door open?
11. Will the room be installed indoors or outdoors?
12. Is rapid cooling required before normal storage?

A cold room should be designed around these conditions instead of selecting a standard refrigeration unit and expecting it to suit every product.

Frequently Asked Questions

Final Storage Reminder

The coldest possible setting is not always the safest or most effective one.

Fresh fish needs near-ice conditions. Leafy vegetables need cold air with very high humidity. Bananas and mangoes require warmer storage. Chocolate needs cool, dry conditions. Pharmaceuticals need dedicated storage based on their approved labels.

The right cold room is therefore selected around the product, incoming load, humidity, airflow, storage duration and daily operating pattern.
