Description

DETAILED DESCRIPTION OF THE INVENTION

(1) In the present context the term “sugars” in this document will be defined as a mixture of mono- and di-saccharides. For example, sucrose, glucose, fructose, maltose are sugars according to this definition. Moreover, the term “sugar” will be defined as sucrose, or common sugar.

(2) It has been found that with a composition for coating a frozen confection, wherein said composition comprises 10 to 50 wt. % dry glucose syrup with a DE (Dextrose Equivalent) below 40, and with a total amount of mono and di-saccharides below 10 wt. %, and a water activity below 1.0, preferably below 0.6, and 35 to 70 wt. % fat,

(3) it is possible to obtain a coating meeting the requirements of the operational parameters without impact on coating breakage or cracks, and having a reduced the amount of sugar while keeping the physical characteristics of said coating.

(4) Surprisingly, it has been observed that dry glucose syrup with a mono and di-saccharides content below 10% (% in weight) have a low hydroscopic behaviour. By “low hydroscopic” is meant a product having a limited tendency to absorb water from its surrounding environment.

(5) During the manufacturing the coating, a hydroscopic dry glucose syrup would pick up any ambient humidity and increase the viscosity of the coating (especially yield value). Furthermore the water activity of the thus produced coating would be higher, which would make it prone to microbiological activity and therefore having a shorter shelf life. During the coating application the coating would further increase in viscosity and thus the coating step would be difficult to control. Caking issues should also be mentioned.

(6) By “dry” glucose syrup is meant glucose syrup containing less than 5% water.

(7) Dry glucose syrup according to the present invention may preferably have a DE comprised from 20 to 40, more preferably from 25 to 40, even more preferably from 30 to 35. Dry glucose syrup with the DE value indicated is commercially available from e.g. ingredient suppliers Tate & Lyle or Tereos.

(8) By “water activity” is meant the partial vapor pressure of water in a substance divided by the partial vapor pressure of pure water at the same temperature. Using this particular definition, pure distilled water has a water activity of exactly one. Higher water activity substances tend to support more microorganisms. Bacteria usually require at least 0.91, and fungi at least 0.7.

(9) In a preferred embodiment the dry glucose syrup according to the present invention: the dry glucose syrup does not contain any polyols, for example mannitol or sorbitol, and/or the dry glucose syrup comprises less than 5% dextrose, preferably below 3% and/or the dry glucose syrup comprises less than 8% maltose.

(10) In a preferred embodiment of the invention, the composition additional comprises below 25 wt. % sugars, preferably 5 to 22 wt. %.

(11) According to a particular embodiment of the present invention, said sugars are selected from the group consisting of sucrose, glucose, fructose, maltose or a combination thereof.

(12) Furthermore, when considering a composition containing said sugars, the dry glucose syrup may be present in an amount of 10 to 30 wt. %.

(13) Advantageously the dry glucose syrup according to the present invention may therefore replace a portion of the sugar in order to obtain a sugar reduced coating composition.

(14) In another embodiment, the present invention is drawn to compositions wherein the dry glucose syrup is present in an amount of 15 to 50 wt. %.

(15) In a particular embodiment the dry glucose syrup according to the invention may replace all the sources of sugar (sucrose). In other word, the ice cream coating thus obtained contains no other ingredient than the dry glucose syrup for sweetening the composition.

(16) In a preferred embodiment, the composition according to the present invention contains fat, wherein said fat has a saturated fat level (SFA) below 60%.

(17) The composition according to the present invention may be combined with known techniques to reduce the fat and SFA (saturated fatty acid) content of chocolate containing coating: EP2099313 (Nestec), and EP2367441 (Unilever). These patents neither address the problem of reducing the amount of sugar in the coating nor suggest the use of dry glucose syrup in a coating formulation.

(18) Fat and sugars are homogeneously mixed within the composition for coating a frozen confection. Solidification step of said composition is related to the crystallization of fat molecules. Crystallization of fat molecules will be influenced by the presence of other molecules, and any modification in the composition may have an influence on this crystallization/solidification step. Texture (SNAP, or brittleness) of the coating of a frozen confection may be considered as a driver for consumer preference, therefore it is important to maintain this characteristic.

(19) Suitable fats for the composition according to the present invention may be selected from the group consisting of: coconut oil, palmkernel oil, palm oil, palm oil fractions, sunflower oil, olive oil, soybean oil, rapeseed oil, corn oil, cottonseed oil, groundnut oil, shea oil, mango kernel oil, or combination thereof. Preferably the fats are selected from the group consisting of: palm oil mid fraction, sunflower oil, rapeseed oil or a combination thereof.

(20) In a preferred embodiment, the composition of the invention contains fat comprising from 8 to 15 wt. % liquid oil, and 20 to 62 wt. % palm oil mid fraction, the weight being based on the total weight of the composition.

(21) Preferred liquid oil according to the composition of the present invention are sunflower oil, olive oil, soybean oil, rapeseed oil, corn oil, cottonseed oil, groundnut oil, or a combination thereof.

(22) In one particular preferred embodiment of the invention, the liquid oil is sunflower oil.

(23) In another particular preferred embodiment of the invention, the liquid oil rapeseed oil.

(24) Both sunflower and rapeseed oils are particularly suitable in the scope of the present invention because they have a low SFA content, no off flavour and are reasonably priced.

(25) According to the present invention, the composition may comprise 0.1 to 2 wt. % of emulsifiers selected from sunflower lecithin, soya lecithin polyglycerol polyricinoleate (PGPR; E476), ammonium phosphatide (YN; E442) or a combination thereof.

(26) According to another embodiment, the composition of the present invention may further comprise from 5 to 25 wt. % cocoa solids non-fat.

(27) Below 5% the taste of cocoa will not be strong enough to be perceived by consumers as cocoa flavour, more than 25% is usually not suitable due to a very strong and bitter taste.

(28) Furthermore, the composition according to the present invention may in a preferred embodiment comprise from 1 to 20 wt. % non-fat milk solids. Below 1% non-fat milk solids, the color, flavour and texture of the composition is not satisfactory from a sensory point of view. Above 20% non-fat milk solids, no additional benefit is achieved.

(29) In another embodiment the invention relates to a process for producing a coating composition as described above, said process comprising the steps:

(30) blending the dry glucose syrup in the liquid oil,

(31) adding the remaining ingredients to the blend, and afterwards

(32) grinding the blend to obtain the composition.

(33) In a further embodiment the invention relates to a process for producing a coating composition as described above, said process comprising the steps:

(34) mixing the dry glucose syrup with the other dry ingredients of the composition,

(35) blending the dry mixed ingredients in the oil, and afterwards

(36) grinding the blend to obtain the composition.

(37) It is important to immerge the glucose syrup in oil before grinding. If the ingredients are all dry refined, amorphous structures are created, which are prone to pick up moisture (hygroscopic). This would negatively impact the viscosity of the coating composition.

(38) The invention also relates to a process for producing a coated frozen confection, the process comprising providing a coating composition according to the present invention and coating a frozen composition.

(39) In a preferred embodiment, the invention relates to a frozen confection coated with a composition according to the present invention.

(40) Preferably, the frozen confection according to the present invention may have a coating thickness from 0.5 to 5 mm.

(41) Furthermore, the frozen confection according to the present invention may be ice cream.
