Abstract: The .alpha.-chlorohydrin content of liquid hydrolysed protein obtained by acid hydrolysis with hydrochloric acid is reduced by adjusting the pH of the liquid hydrolysed protein to a pH of from 8 to 14 and holding the liquid for a time sufficient for the .alpha.-chlorohydrin content of the liquid hydrolysed protein to be reduced.

Abstract: A mixture of a dry carbonating complex of Ca.sup.++ DCS, sugar and flavoring provides an instant mousse mix for enabling preparation of a mousse dessert. The Ca.sup.++ DCS is incorporated in the mix in an amount of from 5% to 45% by weight based upon the total weight of the mix. A mousse dessert may be prepared from the mix by adding heavy cream or milk to the mix. For mixes intended to be prepared with milk, a creamer or whipping agent is included as a further component of the mix.

Abstract: Dry, stable carbonating agents comprised of a carbohydrate/metal bicarbonate complex are disclosed. The complex is prepared by reacting a carbohydrate with a metal hydroxide or oxide at a temperature not exceeding 25.degree. C. to form a carbohydrate/metal hydroxide adduct to which carbon dioxide is then introduced to form the complex. The complex is then immediately dried, preferably by freeze drying. The carbonating agents are particularly useful as components of dehydrated beverage powders. Upon rehydration, the complex releases carbon dioxide and carbonates the beverage. Additionally, upon rehydration the complex promotes the solubilization of the carbohydrate components in the beverage.
