LOW SHEAR INVERSION PROCESS AND PRODUCTS THEREOF

摘要

It is an object of the present invention to provide a reduced fat butter which is butter-like without being cheese-spread like. In particular, the invention aims to provide a 55-65% butter-fat based spread with a butter-like texture using a simple process of low shear inversion. The additional problems faced include avoiding the high levels of caseinate previously found necessary for inversion and avoiding the costly 16 hr ripening step previously required. A reduced fat butter which has a good butter-like texture by inversion of a concentrated cream in the form of a partially crystallised viscous paste. In particular, by phase inversion under conditions of low shear of a cream comprising from 55-65%wt butterfat and 35-45%wt of a gelled or thickened aqueous phase, wherein the cream is in the form of a partially crystallised viscous paste and wherein the C value of said paste at 20.degree.C lies between 50 and 1500. Suitable aqueous phase thickeners are gelatine and caseinates. The viscosity of the aqueous phase should be such that at 20.degree.C less than 20 ml of a 100 ml sample of the paste is discharged from a Ford viscosity cup type FB 11 having a fixed stainless steel nozzle (no 4.) in 2.5 minutes.
