Abstract
Described herein is a composition including at least one product from a corn fermentation process stream, and at least one first additive including at least one anionic surfactant of formula (I), and/or at least one polyethoxylated sorbitan ester of general formula (II). Also described herein is a method of increasing the amount of corn oil recovered from at least one product from a corn fermentation process stream. Also described herein is a method of using at least one first additive for increasing recovery of corn oil from at least one product obtained from a corn fermentation process stream.
Claims36
A composition comprising
- A. at least one product from a corn fermentation process stream;
- and
- B. at least one first additive comprising:
- i. at least one anionic surfactant of formula (I)
- R1O(D)p(E)qSO3−M+ (I)
- wherein
- R1 is linear or branched, unsubstituted C6-C22 alkyl,
- D denotes CH(CH3)—CH2—O—,
- E denotes CH2—CH2—O—,
- p is an integer in the range from 0 to 10,
- q is an integer in the range from 0 to 35, and
- M is H or alkali metal or ammonium cation;
- and/or
- ii. at least one polyethoxylated sorbitan ester of general formula (II)
- wherein
- R, R′, R″, R″′ are each independently H or COR2 with a proviso that at least one of R, R′, R″ and R″′ is not H,
- R2 is linear or branched, substituted or unsubstituted C6 to C20 alkyl or alkenyl, and
- w, x, y, z is independently an integer in the range of 0 to 30,
- wherein the sum of w+x+y+z is at least 5.
The method of use according to claim 34, further comprising using at least one second additive comprising at least one anionic surfactant, other than anionic surfactant of formula (I), and/or at least one non-ionic surfactant.
