  • Patent number: 4177293
    Abstract: This invention relates to the manufacture of butter-spread, which when compared with butter contains a substantially lower fat content, i.e. between about 19-48%, and increased protein content of between about 4.6 to 7.7%. The manufacturing process starts from cream, possibly from a mixture of cream and vegetable oil which is enriched by the addition of dried milk or protein concentrate. The mixture is pasteurized, homogenized, and fermented by clean milk cultures. By repeated homogenization and addition of a stabilizer, a consistency similar to butter with very good spreading characteristics even at refrigerated temperatures is achieved. The product is durable and has acceptable shelf life even without the addition of preservers.
