Described is a process for preparing dry acetaldehyde by means of freeze-drying or spray-drying a mixture of a modified food starch, water and acetaldehyde at a pH in the range of from about 7.2 up to about 7.5. The resulting product contains food grade acetaldehyde but does not contain any other by-products which are detrimental to the use of the material in foodstuffs, e.g., crotonaldehyde. |
