US 4,478,855 A · Protein containing fruit drink and process for the manufacture thereof

Abstract

A protein containing fruit juice drink comprising a fruit juice portion of 10-85% containing a citrus juice portion, a milk raw material portion of 90-15 percent by weight in which the milk raw material portion comprises whey proteins in an amount of 0.5-10 percent by weight of the finished product, and, as a sweetner, a hydrolyzed lactose, made of substantially pure lactose prepared from whey or a permeate from ultrafiltration of milk or whey, containing pure glucose and galactose derivate. In the manufacture of the juice product of the aforementioned type a whey protein solution is prepared and the fruit juice is added while stirring the mixture. Hydrolyzed pure lactose is prepared by dissolving pure lactose crystals, obtained from whey or from a permeate of ultrafiltration of milk or whey, in pure water and hydrolyzing the lactose solution at a temperature of 60.degree.-150.degree., whereupon the pure glucose-galactose product thereby obtained is admixed in the protein containing fruit-juice solution, whereupon the combined solution is pasteurized, homogenized, cooled and packed.

Dependent claims

A homogenized and pasteurized protein containing fruit juice drink comprising a citrus juice portion or a corresponding amount of citrus aromas in an amount of 10-85% and a milk raw material portion in an amount of 90-15 percent by weight, in which the milk raw material portion includes 0.5-10 percent by weight of whey proteins, said fruit juice drink containing, as a sweetener, 2.5-20 percent by weight of hydrolysed lactose consisting essentially of a salt- and taste-free pure glucose--galactose derivative prepared by dissolving pure lactose crystals, obtained from whey or a permeate from ultrafiltration of milk or whey, in pure water and hydrolysing the lactose solution by means of a cation exchanger, said fruit juice drink further containing 0.05 to 0.2% of a polysaccharide stabilizer comprising galactose derivate or galacturonic acid.

A process for the manufacture of a homogenized and pasteurized protein containing fruit juice drink according to any of the preceding claims and comprising a citrus juice portion or a corresponding amount of citrus aromas in an amount of 10-85% percent by weight and a milk raw material portion in an amount of 90-15 percent by weight, comprising the steps of

preparing a protein solution having a whey protein content of 0.5-10 percent by weight, as calculated on the product ready for drinking,
mixing one or several fruit bases including at least a citrus juice portion or a corresponding amount of citrus aromas into the protein solution,
making a lactose solution consisting essentially of glucose-galactose derivate by dissolving pure lactose crystals, obtained from whey or a permeate from ultra filtration of milk or whey, in pure water and hydrolysing the lactose solution,
mixing the hydrolysed lactose solution, in an amount of 2.5-20 percent by weight, into the protein-fruit solution,
adding 0.05 to 0.2% by weight of a polysaccharide stabilizer comprising galactose derivative or galacturonic acid,
stirring the resultant solution, pasteurizing the stirred solution, and homogenizing the stirred solution at a pressure of 30-250 bars before or after said pasteurizing, and then
cooling and packing the stirred, homogenized and pasteurized solution to obtain a protein containing fruit juice drink.
