Abstract

A spread having a low level of saturated fat and cholesterol, a high level of polyunsaturated fat and good organoleptic properties is prepared by adding a fat, preferably a vegetable fat-based cream to a milk base such as skim, semi-skimmed or low fat milk and churning the mixture by conventional butter-making techniques. The cream is prepared by adding a blend of vegetable oils such as soya oil and hydrogenated soya oil and an emulsifier such as lecithin to an aqueous phase. The aqueous phase preferably comprises a pasteurised blend of water and a stabiliser such as gelatin.

Description

A Spread The invention relates to a spread and to a method for preparing a spread. In particular, the invention relates to a non milk fat spread or a blend of milk fat and non milk fat spread and to a method for the preparation thereof.
The term "milk base" as used in this specification refers to any suitable milk base including buttermilk, wholemilk, skim milk, semi-skimmed milk, cream or a combination of any or all of these.
According to the invention there is provided a method for preparing a spread comprising: forming a fat-based cream by blending a fat phase and an aqueous phase, the fat being coated by a membrane such that the fat substantially mimics milk fat, adding the cream product to a buttermaker in combination with a milk base, and preparing a spread by churning the cream product in combination with the milk base.
In one embodiment of the invention the membrane is formed by an emulsifier. Preferably the membrane also includes a stabiliser.
Preferably the emulsifier is lecithin.
Preferably the stabiliser is a hydrocolloid such as gelatin.
In a preferred embodiment of the invention the emulsifier is added to the fat.
Preferably the stabiliser with or without the emulsifier or part thereof is added to the water phase.
Protein (except a substantial amount of casein) with or without an emulsifier and\or a hydrocolloid may be used to form the membrane. Preferably the protein is whey protein.
In one embodiment of the invention the vegetable fat comprises a blend of vegetable fats which has a similar melting point profile to milk fat over the range 5 to 38"C.
Preferably the blend comprises a solid vegetable fat and a vegetable fat which is liquid at room temperature.
The solid and liquid fats may have the same or different origins.
Preferably the solid vegetable fat comprises hydrogenated soya oil and/or hydrogenated coconut oil.
Preferably the liquid vegetable fat comprises soya oil.
Preferably the water is heated to approximately 80"C for pasteurisation prior to addition of the vegetable fat and the vegetable fat and the aqueous phases are blended to uniformly distribute the fat phase in the aqueous phase. The blend may be homogenised in one or more stages, the or each stage being at a pressure of from 100 to 4,000 psi, and at a temperature in the range of approximately 400C to 700C.
Further processing of the spread is by conventional butter making techniques.
The invention also provides a spread whenever made by the process of the invention.
The invention also provides a fat-based cream product for use in spread making which comprises a fat or blend of fats blended with water in the presence of ingredients which form a membrane around the fat so that in spread making the fat substantially mimics milk fat.
In one embodiment of the invention the membrane is formed by.
an emulsifier. Preferably the membrane also includes a stabiliser.
Preferably the emulsifier is lecithin. Preferably the stabiliser is a hydrocolloid such as gelatin.
In another embodiment of the invention the membrane is formed by a protein excluding a substantial amount of casein with or without an emulsifier and/or stabiliser, the protein preferably comprising whey protein.
In one embodiment of the invention the fat is a vegetable fat or blend of vegetable fats.
In one embodiment of the invention the vegetable fat comprises a blend of vegetable fats which has a similar melting point profile to milk fat over the range 5" to 380C, preferably the blend comprises a solid vegetable fat and a vegetable fat which is liquid at room temperature.
The solid and liquid fats may be of the same origin such as soya or coconut, or the solid and liquid fats may be of different origins.
Typically the solid vegetable fat comprises hydrogenated soya oil and/or hydrogenated coconut oil and preferably the liquid vegetable fat comprises soya oil.
The invention will be more clearly understood from the following description given by way of example only.
The cream used in preparing the spread was prepared from the following ingredients: 40.00% fat 59.76% water 0.60% stabiliser (a hydrocolloid such as gelatin) 1.00% emulsifier (in these cases lecithin) (percentages of stabilisers and emulsifiers are by weight of total fat).
Example 1 The fat used was a blend of soya oil and hydrogenated soya oil.
The fat is pasteurised by heating to approximately 80"C and the lecithin emulsifier is added.
A pasteurised blend of water with or without a stabiliser such as a hydrocolloid, for example gelatin, is heated to approximately 600C.
The hot fat phase is then added to the water phase to cool the fat phase to approximately 6 OOC - 70 C. The fat-in-water emulsion is then blended to uniformly distribute the fat in the aqueous phase.
The blended mixture may then be homogenised by a two stage homogenization process at a pressure in the range 100 to 4,000 psi and at a temperature of between 40 and 700C.
To prepare a spread, the cream product is added to buttermilk, wholemilk, skim milk, semi-skimmed milk, cream or a combination of any or all of these, pasteurised and chilled.
The blend is tempered and then churned in a buttermaker in a conventional manner.
The spread is then produced using conventional butter making techniques. The spread has approximately 60% to 90% fat.
The spreads prepared by the methods described are low in saturated fat and cholesterol and high in polyunsaturated fat and have good organoleptic properties.
If desired a suitable colouring agent such as Annato or ss.
Carotene may be added to the cream product.
Any suitable fat such as vegetable fat or blend of vegetable fats may be used. Depending on the fat used a spread of any desired fat content or consistency may be prepared. Generally a vegetable fat or blend of vegetable fats are used. The vegetable fat or blend of vegetable fats are selected such that when coated by a membrane the fat behaves somewhat like conventional milk fat in butter production. The term "conventional milk fat" in this context refers to milk which is substantially in a natural i.e. non-homogenised form in which form the milk does not have any substantial coating of casein.
We have found that by coating the fat with a suitable membrane the fat will substantially mimic the properties of conventional milk fat in butter making, the coated fat being released during churning.
The membrane may be formed by a mixture of an emulsifier such as lecithin and a stabiliser such as hydrocolloid, for example gelatin. The emulsifier may be soluble in fat in which case it is added to the fat phase or may be soluble in water in which case it is added to the aqueous phase.
We have found that lecithin alone may form an adequate membrane, however with higher concentrations of lecithin there may be a sacrifice an organoleptic properties. This effect may be offset by including a small amount of hydrocolloid such as gelatine.
Alternatively experiments to date have indicated that a suitable membrane may also be formed using a non-casein protein such as whey protein.
The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
