- Vegetables, clean very well under water.
- Cucumbers and courgettes contain a lot of moisture and cannot be vacuum packed.
- Herbs with a high oil content like thyme, mint or rosemary can best be vacuum packed in dried condition.
- Herbs like basil, tarragon, dill, parsley and chives can be best frozen first and dried to prevent loss of aromatic flavors.
- Soft mushrooms will turn mushy. Mushrooms can better be washed, cut, dried and frozen before vacuum packaging. During preparations don´t defrost the mushrooms but use directly in the cooking process
