Raspberries yield: how much is usable after prep (AP to EP %)
Raspberries: about 96% usable going fresh to picked over, with a published range of 91–99%. That is a cost factor of 1.04: for every kilo you need ready to use, buy 1.04 kg as purchased.
Yield by preparation stage
| Stage | Average | Range | What is lost | USDA item |
|---|---|---|---|---|
| Fresh → picked over | 96% | 91–99% | Stems and spoiled berries | 2156 |
| Frozen → thawed and drained | 50% | 44–58% | Juice drained off | 2164 |
Frozen raspberries lose half their weight as juice if you drain them. Use them where the juice stays in, such as a coulis or a trifle, and buy fresh for plating.
