Benefits of technology

[0028]The acidified milk based beverage is preferably delivered with a protein content of from 0.02 to 5% SNF and with sugar equivalent of from 7 to 10 weight %. The beverage is also preferably delivered with a pH comprised between 3...

Problems solved by technology

Most of the acidified milk based beverages are available today as “ready-to-drink” beverages, which require storage at refrigerated conditions and, consequently, which have a limited shelf life.
When refrigerated conditions like those which should apply to “ready-to-drink” milk based beverages are ...

example 1

[0068]40 g sucrose and 45 g of partially skimmed milk were mixed at 50° C. with added hydrated solution of stabilizers such as K-carrageenan and pectin. The solution was heat treated for 2 minutes at 120° C. to denature the proteins, then homogenized and cooled down to 4° C.

[0069]The pH of the solution was quickly adjusted to 3.5 with agitation by addition of 30% citric acid solution. Colours and flavours are added at this stage. The acidified product (with viscosity of 50 mPa·s) was mixed for 30 minutes and then pasteurized and poured aseptically into storage containers.

[0070]The resulting base concentrate had 2.40% weight of SNF and 40% weight of sugar equivalent.

[0071]Such a product will be consumed after dilution of 1 part of concentrate with 4 parts of water giving acidified milk based beverage having a final pH of 4.0.

example 2

[0072]20 g sucrose and 45 g of partially skimmed milk were mixed at 50° C. with added hydrated solution of stabilizers such as K-carrageenan and pectin. To increase the sweetness level, 0.02 g of sucralose from Splenda® was added to the mixture. The solution was heat treated for 1 minute at 100° C., then homogenized and cooled down to 4° C.

[0073]The pH of the solution was quickly adjusted to 3.5 with agitation by addition of 30% citric acid solution. Colours and flavours are added at this stage. The acidified product (with viscosity of 45 mPa·s) was mixed for 30 minutes and then sterilized and poured aseptically into storage containers.

[0074]The resulting base concentrate had 2.40% weight of SNF and 32% weight of sugar equivalent.

[0075]A final milk based beverage having a pH of 4.0 has been obtained by dilution of 1 part of the base composition with 4 parts of water.

example 3

[0076]46 g sucrose and 33.4 g of fresh whole milk and 1.5 g of skimmed milk powder were mixed at 50° C. with added hydrated solution of pectin. The solution was heat-treated, then homogenized and cooled down to 20° C.

[0077]The pH of the solution quickly adjusted to 3.3 with agitation by addition of 30% citric acid solution. Colours and flavours are added at this stage. The acidified product (with viscosity of 60 mPa·s) was mixed for 30 minutes, sterilized and poured aseptically into storage containers.

[0078]The resulting base concentrate had 4.40% weight of SNF and 46% weight of sugar equivalent.

[0079]A final acidified milk based beverage is prepared by dilution of 1 part of base composition with 5 parts of water leading to final pH of 4.0.

Abstract

A shelf-stable liquid base composition useful for preparing acidified milk based beverages, e.g. by dilution with water in a beverage dispensing machine, comprises: from about 2 to about 10 weight % of denatured milk proteins expressed as solid-not-fat (SNF) milk components; from about 15 to about 80 weight %, expressed as sugar equivalents, of a carbohydrate based or non carbohydrate based sweetener; from about 0.35 to about 1.50 weight % of a carbohydrate based stabilizer; and an acidifying agent present in amounts necessary for achieving a pH of about 3.0 to about 3.8 of the said base composition. Methods for preparing such a base composition and acidified milk based beverages prepared by means of such a base composition.

Description

FIELD OF THE INVENTION[0001]The present invention relates to beverages, more precisely to shelf-stable liquid base compositions useful for the preparation of acidified milk based beverages, especially by means of beverage dispensing machines.BACKGROUND OF THE INVENTION[0002]Acidified milk beverages are very popular today as they offer simultaneously sweetness and freshness to consumers. These beverages further provide well known milk nutrients like proteins or minerals and, when acidity is achieved by means of fruits juices, the latter further bring flavours or vitamins in addition to the mere acidifying effect.[0003]Most of the acidified milk based beverages are available today as “ready-to-drink” beverages, which require storage at refrigerated conditions and, consequently, which have a limited shelf life. Several attempts have been made in the past to increase stability and storage period of said “ready-to-drink” beverages, e.g. by controlling pH with suitable stabilizers, increa...
