DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a process for producing a butter-like food fat, which is directly spreadable at refrigeration temperature, i.e. 4 to 5.degree. C., and which preferably contains 80 to 83% fat, said process including addition of vegetable and/or animal oil, where butter-milk is produced as a by-product.
BACKGROUND ART
For instance Danish Printed Accepted Application No. 152.245 discloses a process of the above type, where the main portion of the total amount of added vegetable and/or animal oil is added and mixed with conventionally soured or unsoured cream before the churning, whereafter the remaining amount of vegetable and/or animal oil is added at the kneading station of the butter machine. The resulting ready-made butter-like food fat contains an amount of 15 to 30% of vegetable and/or animal oil. The addition of the major portion of the vegetable and/or animal oil to the cream before the churning has the effect that some of the oil is lost in the buttermilk always being a by-product of the butter production. Therefore, the buttermilk contains vegetable and/or animal fat not being butter fat. In addition, it is necessary to reduce the churning temperature to 5 to 6.degree. C., which is too low for ensuring the lowest possible consumption of energy in the butter machine and the lowest possible loss of fat in the buttermilk. The content of foreign fat/oil in the buttermilk prevents said buttermilk from being used as a market product, and therefore it can only be used as a feedstuff product. Accordingly, the market price of the buttermilk is reduced to a minimum.
GB-A-2 021 140 discloses a process for producing a butter-like food fat being well spreadable at refrigeration temperature from ready-made butter by admixing vegetable oils and stabilizer to said butter during a heating of the mixture to 30 to 35.degree. C. According to the publication it is necessary that the stabilizer is admixed water and added to the softened butter before the vegetable oil is added to the mixture.
The consistency of the butter-like food fat is softer than the consistency of conventional butter, and therefore it is necessary to use plastic cups as packing for the butter-like food fat, other materials, such as an aluminium sheet, being unacceptable as packing. In order to utilize the total capacity of a butter machine it is therefore necessary that the same capacity applies to the succeeding cup-filling line for the butter-like food fat as the capacity applying to the aluminium sheet-packing line for the conventional butter, only one line being usable at a time by such a procedure.
BRIEF DESCRIPTION OF INVENTION
The process according to the present invention is characterised by continuously passing conventional butter preferably containing 80 to 83% fat and exclusively being produced from milk through a tight, closed plant, whereby the butter initially passes through a kneading station and subsequently through a mixing station, where the vegetable and/or animal oil as well as water are added. In this manner the buttermilk results exclusively as a by-product from the production of a conventional butter, and accordingly it only contains pure milk fat. The resulting buttermilk can be used as a market product and sold at the highest possible market price. Furthermore it is possible to optimize the initial production of conventional butter so as to involve the lowest possible consumption of energy and loss of fat in connection with a 100% butter capacity, and the conventional butter can be advanced according to desire for packing or for further processing so as to allow production of the butter-like food fat followed by packing. In this manner it is possible on the same production plant to simultaneously produce conventional butter and the butter-like food fat. The butter-like food fat does not contain any emulsifier, stabilizer or other "chemical" additive, which today is of increasing importance to the consumers.
According to the invention the first portion of the total amount of added vegetable and
