How It Works
Prime Fresh preserves your food in a soft frozen state to lock in the maximum amount of flavor and nutrients.
Soft freezing at approximately -3°C ensures the water inside the food doesn’t expand and cause cell damage.
Prevents Fat Oxidation
Soft freezing stops the fat in food from oxidizing to maintain optimal freshness and taste.
Why Is -3°C Optimal For Maintaining Freshness?
Not Ideal (-18°C)
Food is hard and difficult to cut, while flavor is lost due to cell damage.
Ideal Temperature (-3°C)
Food is easy to cut without defrosting. Freshness and flavor can be retained for 7 days*¹.
Not Ideal (4°C)
Food is too soft to cut neatly and only stays fresh for a few days.
Tastier Meals With Prime Fresh
-3°C soft freezing keeps ingredients fresh so you can prepare mouthwatering dishes.
Retains Freshness For Up To 7 Days
Meat and fish remain fresh and flavorful for up to a week.
Soft freezing protects ingredients from cell damage and drip for better flavor.
Convenient & Time Saving
Ingredients stored with Prime Fresh don’t require defrosting and can be seasoned quickly.
Retains Freshness for Fish
Soft freezing prevents seeping of blood for long-lasting freshness.
Retains Freshness for Meat
Nutrients and flavors are locked in with no visible drip or color change.
Preserves Freshness Longer Compared to Chilled
Less oxidation means soft frozen food stays fresh for longer.
Prevents Cell Damage
Less cell damage helps food stay fresh without losing flavor or nutrients.
Soft freezing prevents drip to retain “umami ” (savoury) flavor.
Retains Essential Nutrients
Nutrients stay locked in food since no defrosting is required.
Fuss-Free Meal Prep
Easy To Cut
Soft freezing enables easy cutting of meat without defrosting.
Easy to Scoop
Scoop out just the desired amount of soft frozen cooked food such as soups and sauces.
Easy to Peel
Ham slices that stick together when frozen can peel apart neatly with -3°C soft freezing.
Flavors can penetrate faster for even more delicious results when marinated or seasoned food is soft frozen at -3°C.

Soft freezing retains the freshness of meat and fish longer compared to chilled storage. Soft frozen food can also be cooked immediately without defrosting, giving you extra convenience on days where you’re strapped for time.
*1 Data prepared by Panasonic. The effect differs depending on operating conditions, and the type, condition and amount of food stored.
*2 Test conditions — Ambient temperature: 32°C; Hertz: 50Hz; Voltage: 220V; Tested model: NR-BC369-V2/Temperature settings — Fridge: Med; Freezer: Med; Prime Fresh: Prime Fresh+/Normal Prime Fresh/Food tested: 200g of beef kept in the fridge (at approx. 4°C) and 200g of beef kept at room temperature (at approx. 26°C)/Test method: Both types of beef were placed in the Prime Fresh Case after the refrigerator that is running reaches a stable state. The time for cooling speed was compared from 4°C/26°C to -1.5°C between the Prime Fresh+ mode and the Normal Prime Fresh mode.
