IQF (Individually Quick Frozen) raspberries are processed and frozen for longer shelf life and versatility. Some of the most common types include:
Whole IQF Raspberries
These are the most common type of frozen IQF raspberries. They are used widely because of their versatility. These whole berries maintain their shape and are perfect for adding whole to smoothies, baking goods, or making desserts. They also work well when used in jams or sauces.
IQF Raspberry Crumbles
IQF raspberry crumbles are whole raspberries that have been lightly processed to break them up into smaller pieces or crumbles. These are ideal for products like raspberry sauces and jam where whole fruit isn’t desired. Raspberry crumbles can also be used in baking goods where the fruit is mixed throughout the dough.
Iqf Raspberries Unsweetened
These are whole or sliced raspberries that have been frozen without any added sugar. Unsweetened IQF frozen raspberries are ideal for customers who want to control their sugar intake. They are suitable for making smoothies, baking goods, or preparing sauces that require less sweetness.
IQF Sliced Raspberries
These are IQF raspberries that have been sliced for easier use in certain applications. Sliced raspberries are particularly useful in bakery products like pastries, cakes, or muffins where whole fruit may not be practical. They can also be used in breakfast products like yogurt or oats since they distribute more evenly.
IQF Raspberries with Sugar Added
These are whole or sliced fruit that has been mixed with a small amount of sugar before freezing. Sweetened IQF frozen raspberries are ideal for customers who want sweeter, more convenient fruit. They are perfect for pies, cobblers, and desserts where the fruit needs to be naturally sweetened.
Frozen raspberry products, especially during the processing stages, need specific ingredients and materials to ensure they are of food-safe quality.
Fresh Raspberries
The main raw material used in making frozen raspberry products is fresh, ripe raspberries. These are usually sourced from large-scale commercial farms, ideally located in regions with optimal growth conditions for raspberries.
Sugar or Sweeteners
During the production of sweetened IQF raspberries, a small amount of sugar or alternative sweeteners like stevia and sucralose are added. This is mainly for sweetened frozen raspberry products. The sugar acts as a preservative as it inhibits the growth of bacteria and molds.
Citric Acid
This is a naturally occurring weak acid that is often added to frozen raspberry products. Citric acid helps to stabilize the fruit by lowering the pH and acts as an antioxidant. It’s also responsible for the tart flavor of raspberries and is frequently found in jams, jellies, and other fruit-based products.
Packaging Materials
Frozen raspberry products are packaged in food-grade, moisture-resistant bags or containers. It helps maintain the quality and freshness of the raspberries by preventing moisture and air from degrading the product after it has been frozen.
Modified Atmosphere Packaging (MAP)
This is a special type of packaging that reduces oxygen levels and replaces them with gases like nitrogen or carbon dioxide.
Food-Grade Lubricants
These are used on the freezing equipment and storage facilities to prevent the frozen raspberries from sticking together. The food-grade lubricant used must be safe for food contact and in compliance with food safety regulations.
IQF raspberries are versatile, convenient, and nutritious, making them popular in various culinary applications. Here are some common uses:

IQF raspberries are a versatile ingredient that can be used in a wide range of culinary applications. The good thing about these frozen berries is that they do not need to be thawed before adding them to things. They can be added whole, pureed, blended, or cooked. This makes them convenient for a variety of recipes.
Thawing and Usual Temperature Applications
For recipes where thawing is desired, simply place the frozen berries in the refrigerator for a few hours or leave them at room temperature for about 30 minutes. Thawed raspberries are ideal for topping desserts like ice cream, pancakes, or waffles. They can be lightly mashed and used as a sauce or syrup.
Thawed raspberries can also be mixed with a bit of sugar and used as filling for pies, tarts, or cobblers. When baked goods use the raspberries, it is recommended to toss them in flour before adding them to the batter. This helps prevent excess moisture from making the dough soggy.
Blending Applications
No thawing is required when using IQF raspberries in smoothies, shakes, or sauces. Just add them directly to the blender with other ingredients. The frozen nature contributes a thick, chilled texture to drinks and can enhance the freshness of sauces.
Baking Applications
Add IQF raspberries directly to pancake or waffle batter. Just be sure to toss them in a bit of flour first. This helps distribute the berries evenly throughout the batter. For pies and cobblers, the berries can be added directly but tossing them in a bit of cornstarch helps absorb any excess moisture.
Sauces andToppings Applications
For raspberry sauce, combine thawed raspberries with sugar and a splash of lemon juice. Blend until smooth and strain if desired. For a simple compote, combine thawed raspberries with sugar and simmer until thickened. This can be used as a topping for desserts, breakfast dishes, etc.
Custards, Cheesecakes, and Gelatin Desserts
Pureed or whole IQF raspberries can be swirled into cheesecake batter before baking for a tasty marbled effect. They can also be mixed into custards or budino for added fruit flavor and texture. Raspberry gelatin desserts can be made by mixing raspberry puree with gelatin and chilling until set.
Frozen IQD raspberries offer year-round availability, extended shelf life, and a consistent supply. Quality and safety are particularly important for berry products due to their high water content and susceptibility to spoilage if not handled correctly. Some key factors include:
Packaging
Places that handle bulk frozen raspberry usually package them in food-grade, airtight bags or containers. This prevents moisture and air from degrading the fruit. Packaging should be sealed tightly without any tears or holes to prevent the build-up of ice in the container. This ensures the berries stay separated and don’t clump together.
Storage Temperatures
IQF frozen raspberries should be stored at temperatures of -18°C (0°F) or lower. This prevents the growth of bacteria, mold, and yeast. The freezers and storage areas should be regularly monitored to ensure that the temperature remains constant. Frozen berries can start to spoil if they fluctuate above freezing.
Handling
To prevent foodborne illness, it’s important for handlers to have clean hands and wear gloves when touching the berries. Avoid letting the fruit thaw and refreeze multiple times. This can lead to a loss of texture and flavor and increase the risk of spoilage.
Product Rotation
Implementing the first-in, first-out method helps ensure that older stock is used before it reaches its expiration date. This reduces the risk of berries spoiling before use and ensures they are fresh for consumption.
