The invention relates to a hot soluble extractable food product such as an instant tea or coffee comprising freeze dried granules that are prepared from an extract containing no more than about 25 % by weight food solids, have a bulk density of no more than about 80 g/l and a Friability Index of less than about 40 % (preferably less than about 30 %, especially less than about 25 %). The term Friability Index is defined and a method of determining same is described. A process for preparing a hot soluble extractable food product is also described which comprises: extracting an extractable food, cooling the extract, aerating the extract with a gas comprising a gas or mixture of gases substantially more soluble than nitrogen or a mixture of nitrogen and a gas or mixture of gases substantially more soluble than nitrogen to produce a foam, substantially freezing than foam, shattering it into granules, and freeze drying the granules to yield the product. |
