Abstract
Cyclic ketal compounds provide excellent foam protection when having at least one moiety of a threshold size (comprising 4 or more carbon atoms) pendant from a ketal carbon. The carbons in such moieties may be present in one or more chains. The cyclic ketal compounds of the present invention are compatible with foodstuff manufacturing. In particular, it has been discovered that the cyclic ketal compounds of the present invention exhibit excellent foam control performance in both potato and sugar beet processing systems.
Claims21
A method of controlling foam during processing of a foodstuff, comprising steps of:
- a) providing a foodstuff;
- and
- b) processing the foodstuff in a composition comprising at least one cyclic ketal compound according to Formula I:
- wherein x is an integer in the range of 1-4, R1, R2, R3, and R4 are independently selected from the group consisting of H, a co-member of a ring-structure with at least one of the other R1, R2, R3, or R4, and a monovalent moiety other than H comprising 0 to 5 carbon atoms, wherein one of R5 and R6 comprises at least one carbon atom and the other of R5 and R6 comprises at least 4 carbon atoms, the at least one cyclic ketal compound according to Formula I present in the composition in an amount in the range of 0.01 weight percent to 5 weight percent.
A foodstuff composition, comprising:
- a) at least one foodstuff;
- and
- b) at least one a cyclic ketal compound according to Formula I:
- wherein x is an integer in the range of 1-4, R1, R2, R3, and R4 are independently selected from the group consisting of H, a co-member of a ring-structure with at least one of the other R1, R2, R3, or R4, and a monovalent moiety other than H comprising 0 to 5 carbon atoms, wherein one of R5 and R6 comprises at least one carbon atom and the other of R5 and R6 comprises at least 4 carbon atoms, the at least one cyclic ketal compound according to Formula I present in the composition in an amount in the range of 0.01 weight percent to 5 weight percent.
