Definitions

  • the present invention relates to tropicalizing agent compositions, to methods for the preparation thereof, to methods of tropicalizing chocolate or analogues thereof, and to chocolate or analogues of chocolate containing the tropicalizing agents.
  • it relates to the use of a novel combination of cocoa particles and the methods of the invention and to their incorporation into tropicalizing agent compositions and products of the invention.
  • chocolate consists of sugars, cocoa solids and protein (usually from milk) homogeneously dispersed in fats and fatty substances originating from cocoa butter.
  • Chocolate analogues contain other vegetable fats in partial/total replacement of the cocoa butter fat.
  • the continuous fat phase also contains dairy fat.
  • Cocoa butter typically starts to soften at about 28°C, with consequent loss of the mechanical strength of the chocolate. This means that at the high ambient temperatures frequently encountered in tropical countries, chocolate becomes sticky or even runny. It tends to stick to the wrapper and fall apart when the wrapper is removed, leaving a semi-liquid mass that can often only be eaten with a spoon if cleanliness is desired. Enrobed chocolate products typically lose integrity under these conditions, with their contents often leaking and individual units tending to stick together in the packaging. Chocolate also loses the ‘snap’ that is an important (and pleasurable) textural characteristic of chocolate stored and eaten under cooler conditions.
  • EP0189469 describes the mixing of a liquid polyol with tempered conventional chocolate mass before depositing it into molds.
  • Polyols that are liquid at ambient temperatures such as glycerol
  • higher melting polyols such as sorbitol
  • the mixture is held at slightly elevated temperatures (24°C to 35°C) for a short period of time during which the viscosity rises. This is stated to be the result of a chemical reaction between the fat and the polyol.
  • the time and temperature of the holding period are critical parameters that control the viscosity increase - the viscosity must remain low enough for the subsequent molding or enrobing operations.
  • a polyol such as glycerol
  • a liquid fat such as molten cocoa butter
  • lecithin as an emulsifier
  • EP0297054 describes a method for homogeneously dispersing water by using an aqueous foam.
  • the foam is stabilized with an edible foaming agent (such as egg albumin) and added to conventionally prepared chocolate mass after tempering.
  • the foam is added at levels that deliver from 0.5 to 2% of water, reportedly with no noticeable increase in viscosity to provide a treated chocolate usable for molding or enrobing.
  • the trapped gases can be removed from the still liquid product by exposing it to reduced pressure.
  • EP0407347 describes a similar method.
  • EP0393327 discloses another variation in which the aqueous phase of the water-in-oil emulsion contains sugars (such as sucrose or glucose) or polyols (such as sorbitol).
  • the emulsion is prepared with 30 to 60% fat using emulsifying agent at a level of 0.1 to 3%.
  • suitable emulsifying agents are lecithin, glycerol fatty acid ester, polyglycerol fatty acid ester, polyglycerol condensed ricinoleic acid ester and sucrose fatty acid ester that has an HLB not more than 7.
  • the level of sugar or polyol in the aqueous phase of the emulsion can be between 20 and 60% and the level of water between 15 and 25%.
  • the sugar or polyol in the aqueous phase is reported to provide smoother texture to the heat-stable chocolate mass.
  • a storage period of about 20 days, however, is required for proper development of internal structure.
  • an oil-in-water emulsion is prepared by mixing 30-80% of an oil or fat (for example, cocoa butter) in water containing a small amount of a suitable emulsifier.
  • This emulsion is mixed at a level of about 5% with a conventionally manufactured and tempered chocolate mass that is then molded. It is stated to be important to control the temperature to be no higher than 90°F to keep the oil-in-water emulsion stable.
  • the homogeneously dispersed water generates a viscosity increase of the chocolate mass during solidification of the finished product. However, it is still necessary to store the molded product for several days to establish heat stability.
  • US5,486,376 describes the use of water-in-oil microemulsions to introduce finely dispersed water into chocolate mass.
  • US6, 159,526 describes addition of water to the chocolate as a water-in-oil emulsion stabilized by sucrose fatty acid esters (HLB ⁇ 3).
  • US 6,159,526 is concerned primarily with adding water-based flavors to chocolate.
  • WO 93/06737 describes methods for making gels/pastes by adding water to “Raftiline” (inulin), starches (potato and corn), “Splendid” (pectin), or Gum Arabic. The paste is then mixed into tempered chocolate that is molded.
  • US5,468,509 describes a method for adding up to 16% water to chocolate.
  • the chocolate supposedly remains moldable.
  • Two mixtures are prepared.
  • (1) Cocoa is coated with cocoa butter in the presence of an emulsifier and (2) water, a sweetener and milk solids are blended to form an aqueous phase.
  • the two are gently blended and the product molded.
  • US5,965,179 aims to circumvent the problems of viscosity increase on the addition of water to chocolate by use of an extruder for processing the chocolate.
  • the water is added as an aqueous gel with microcrystalline cellulose. This gel is injected into the chocolate using a twin- screw extruder so as to form a viscous product containing 3 to 20% of added water.
  • US2005/0118327 describes the preparation of gel beads comprising 20-50% sugar or polyol, water, emulsifying agent and a gelling agent (hydrocolloids).
  • the gel beads are formed by dispersing a hot aqueous sol (90°C-95°C) in a liquid fat in a high shear mixer, to form an emulsion, and then cooling to get gelification of the beads.
  • the gel beads dispersed in fat are blended into molten chocolate mass.
  • One drawback is that the release of the sugar/polyol syrup from the gel beads, requires activation.
  • US2005/0118327 teaches the activation of gel bead degradation by freezing at temperatures of -5°C to -15°C. It is reported that without this cooling it is necessary to store the products for 10-14 days to develop shape retention properties.
  • W091/19424 describes the preparation of gel beads comprising alginate or pectate, divalent metal ions and a sequestrant for the metal ions.
  • the gel beads are used as fat substitutes.
  • EP0688506 describes the preparation of gels comprising polyol or polyol/water with gelling agents and alkali or alkali-earth metal salts.
  • the gels are produced by heating to temperatures of 120°C and are then frozen in liquid nitrogen, before addition to liquid chocolate.
  • These prior art references have drawbacks such as the release of water into the chocolate mass, which occurs early in the process and is not retarded for long enough for the material to be used for typical enrobing processes; the dispersion and release of water is not under sufficiently fine control to avoid development of unpleasantly gritty textures in the final product; and/or activation or an inconveniently long storage time is required for full development of the structures required to provide stability.
  • EP0393327 discloses making an emulsion out of a saccharide and an emulsifying agent and then maturing the chocolate.
  • US5486376 discloses making an emulsion out of monglyceride (50-65%)/lecithin(0-10%)/chocolate fat (CBE/CBR/CB) (15-20%) and water (15-20%).
  • WO2011010105 relates to adding water and propylene glycol to molten chocolate.
  • US4446166 uses water in fat emulsion, where 20% of fat is in solid form.
  • the inventors have developed a further improved route to introduce a humectant into chocolate or an analogue thereof to obtain a heat resistant (tropicalized) chocolate or analogue thereof, which displays improvements in respect of heat resistance without maturation and adversely impacting other properties of the chocolate.

  • Advantageously the tropicalizing agent composition of the present invention requires only few ingredient components, and can be prepared with commercially available food ingredients. No expensive additives are required.
  • the humectant may be used in an amount of between 0.1 and 5% by weight within the chocolate or chocolate analogue based on weight of the final chocolate or chocolate analogue product, preferably between 0.2wt% and 4.5wt%, preferably between 0.35 wt% and 3.5wt%, preferably between 0.40wt% and 2.5wt%, preferably between 0.45wt% and 2.0wt%, preferably between 0.5wt% and 1.0wt%.
  • the tropicalizing agent composition may be added in an amount of between 1.0 and 20% by weight within the chocolate or chocolate analogue. Preferably, they are used in an amount of between 2.0wt% and 15wt%, preferably between 2.5wt% and 17.5wt%, preferably between 2.75wt% and 15.0wt%, preferably between 3.0wt% and 12.0wt%, and more preferably between 3.0wt% and 10wt%.
  • the dispersion of cocoa solids in a portion of the liquid fat component is blended with an emulsion of the humectant component in a second portion of the liquid oil component.
  • Addition of too much tropicalizing agent or composition, or of tropicalizing agent or composition which contains a too high proportion of water and/or humectant liquid component to particulate carrier component, can tend to cause too rapid an increase in viscosity, particularly if multiple of these factors are present, for the product to be suitable for moulding, enrobing, or both. Addition of too little tropicalizing agent or composition can cause a delay in the time over which the desired heat shape stability properties are developed, or even failure to produce the desired heat stability properties.
  • the fat content, e.g. cocoa butter content of the starting chocolate mass, to which the tropicalizing agent composition is to be added is reduced compared to the desired final fat content, by an amount such that the fat content, e.g. cocoa butter, of the tropicalizing agent or composition provides the remaining fat amount, to produce a final chocolate product having the desired fat content.
  • the resultant chocolate products including the tropicalizing agent composition of the invention do not stick to a wrapper, or adopt the shape of the wrapper, at elevated temperatures, even at temperatures as high as 40°C, do not result in adverse appearance or mouthfeel, and in chocolate or analogues thereof do not have adverse effects on bloom.
  • the tropicalized chocolates and chocolate analogues have improved shape retention at elevated temperature, even at temperatures as high as 40°C compared to corresponding regular chocolate or chocolate analogue product without the tropicalizing agent.
  • the tropicalizing agent composition of the invention can be added to any type of chocolate e.g. white, milk, dark chocolate or any intermediate, or any type of chocolate analogue e.g. compound coating.
  • the heat resistance can be expected to develop most effectively in masses containing a high proportion of sugar and milk particulate solids of fine granulometry and relatively low fat content due to the loading and proximity of the building blocks of the particle network.
  • the tropicalized chocolate and chocolate analogues of the invention can advantageously be used in tropical countries where hot weather causes frequent or rapid melting of chocolate, chocolate analogues.
  • chocolate analogues including coatings and covertures, which are thin and tend to melt rapidly can surprisingly and advantageously be formed with the tropicalizing agent of the invention.
  • the tropicalized food products of the invention remain non-sticky so as to smoothly slide out of a wrapper and to avoid leaving food product on the consumer's fingers during consumption.
  • a reference composition was prepared with a composition as follows and using a 3 roll refiner and Lipp Mischtechnichnik GmbH conchee:
  • cocoa liquor is heated to 60°C and cocoa butter is added until liquid and cooled to about 50°C.
  • Glycerol warmed to approx. 50°C is added under high shear (in Hobart planetary whisk) and the mixture is mixed for 3 minutes.
  • the agent is combined with liquid chocolate post-temper, unless specified.
  • the chocolate compositions are stored for one week at ambient conditions (20°C and 50 percent humidity).
  • Heat shock measurement Placed in stove at a set temperature for 1 hour. Removed from stove and hit against flat surface twelve times to cause loss of shape. Reference always present on tray. Data given is in pixels, gives area increase. The larger the figure the less heat stable the mixture created is
  • Unwrapping measurement Placed in stove at set temperature for 1 hour. Visual assessment performed based on mass stuck to wrapper and loss of logo definition when wrapped in standard foil.
  • Mould size is 25mm by 25mm squares with a depth of 7mm.
  • the pixel area of the standard square is 26228 for initial testing (Examples 1&2). From the conching trials onward (including particle size variation and the shelf-life/composition DoE), the camera was adjusted and a new standard was taken at 22000 pixels (all other examples in patent).
  • Cocoa Butter 1 part
  • Cocoa Liquor 4 parts (2 parts Cocoa Butter 2 parts cocoa solids)
  • Glycerol 1 part. Therefore: 17% Glycerol, 50% Fat, 33% Cocoa Solids using the above method.
  • This mixture is then added at 6% to a tempered chocolate mass made using the above recipe with reduced cocoa liquor and butter to have the only recipe change be 1% glycerol addition.
  • Reference Example 2 uses the same base chocolate but uses a commercially available cocoa butter improver, lllexao Sal, a previously used tropical ization agent.
  • the p value for the interaction between Lecithin and Week is 0.576, which indicates the relationship between Lecithin and Week does not depend on the value of Lecithin and Week (i.e. no interaction).
  • the p value for the interaction between Lecithin and Glycerol is 0.01 , which indicates the relationship between Lecithin and Glycerol does depend of the value of Lecithin and Glycerol (i.e. .an interaction).
  • the p value for the interaction between Week and Glycerol is 0.00, which indicates the relationship between Week and Glycerol does depend of the value of Week and Glycerol (i.e. an interaction).
  • Example 2 The composition of Example 2 was wrapped in metallized foil and found to be easy to unwrap and not lose logo definition when kept at the temperatures set out in the above tables. Reference Example 1 was found to melt and become difficult to unwrap.
