Abstract
A process for the washing and/or disinfection of eggs is provided. The process comprises contacting the eggs with a nonionic surfactant, an amphoteric surfactant and an aqueous solution of a peracid. The surfactants and peracid solution may be combined, or may be employed in separate stages. Preferably, the solutions are sprayed onto the eggs, optionally in the presence of an antifoam. The preferred peracid is peracetic acid.
Claims21
A process for the washing and disinfection of eggs, comprising contacting eggs with an aqueous solution comprising:
- i. a nonionic surfactant, and
- ii. an amphoteric surfactant,
- and subsequently contacting the eggs with an aqueous solution comprising an organic peracid, the amount of the surfactants and the peracid being sufficient to effect cleaning and disinfection of the eggs.
A process for the washing and/or disinfection of eggs, comprising contacting eggs with an aqueous solution comprising:
- i. a nonionic surfactant, and
- ii. an amphoteric surfactant, and
- iii. an organic peracid, the amount of the surfactants and the peracid being sufficient to effect cleaning and disinfection of the eggs.
A process for the washing and/or disinfection of eggs, comprising spraying eggs with an aqueous solution comprising:
- i. from 0.1 to 5% by weight of a nonionic surfactant having the general formula
- R--(OCH.sub.2 CH.sub.2).sub.n --(OCH.sub.2 CHCH.sub.3).sub.p --(OCH.sub.2 CH.sub.2).sub.q --O--R'
- wherein R represents an alkyl group having from 6 to 18 carbon atoms, n, p and q each represent an integer, and R' represents an alkyl group having from 1 to 4 carbon atoms or an aryl group having from 6 to 10 carbon atoms
- ii. from 0.01 to 5% by weight of an amphoteric surfactant comprising disodium dicarboxyethyl cocopropylenediamine, and subsequently contacting the eggs with an aqueous solution comprising from 200 to 1500 ppm of peracetic acid.
