[0253] 12.5% of SiO.sub.2 flakes having a particle thickness of 360 nm
in 2000 ml of demineralised water are warmed to 75° C. with stirring. The pH of the suspension is then adjusted to 2.2 using hydrochloric acid (15% HCl). 360 g of a TiOCl.sub.2 solution (400 g of TiCl.sub.4/) are metered in at a metering rate of 2.0 ml/min at constant pH until the colour end point (silver) has been reached, during which the pH is kept constant at 2.2 by simultaneous dropwise addition of 32% sodium hydroxide solution (30% KOH). When the addition is complete, the mixture is stirred for a further 10 min, the suspension is filtered off with suction and washed with deionised water until salt-free. After drying at 120° C., the pigment is calcine at 850° C. for 45 min, giving a silver-white interference pigment mixture with a subtle interference rosé shade, excellent gloss and pure-white mass tone.

The remainder of 100 ml of SnCl.sub.4 solution (22 g/l) is subsequently metered in, during which the pH is kept constant at 1.8 using 32% sodium hydroxide solution. When the addition is complete, the mixture is stirred for a further 10 min. 345 ml of a TiOCl.sub.2 solution (400 g of TiCl.sub.4/) are then metered in at constant pH until the colour end point (silver) has been reached, during which the pH is kept constant at 1.8 by simultaneous dropwise addition of 32% sodium hydroxide solution. When the addition is complete, the mixture is stirred for a further 10 min, the suspension is filtered off with suction and washed with deionised water until salt-free. After drying at 120° C., the pigment is calcined at 850° C. for 45 min, giving an intensely coloured blue interference pigment having a subtle flop into reddish and a pure-white mass tone.

with 1500 ml of deionised water are warmed to 75° C. with stirring. An FeCl.sub.3 solution (FeCl.sub.3 content: 5.4%) is added dropwise at a rate of 0.5 ml/min with a vigorous stirring at 75° C. and pH 3.0. The pH is kept constant by addition of dilute NaOH. After addition of 1100 ml, the product is filtered, washed with demineralised water until neutral, dried and calcined at 800° C. for 30 min, giving an interference pigment changing subtly between copper and gold and having an attractive rosé powder colour.
USE EXAMPLES
Example A1
Sugar-Coated Products—Shellac Application
[0269] Shellac (Capol® 425, Capol GmbH) is mixed with 2 parts of ethanol (food grade, min. 90% by vol.). 2-8% of interference pigment from Example 1 are subsequently added and mixed. The glossed, sugar-coated products are then introduced into a conventional coating pan. Between 5 g and 20 g/kg of the mixture prepared above are then applied over the products rotating in the pan.
[0270] After a few minutes, drying air is directed over the products.
[0271] Sugar dragees having an additional silver-white gloss on the surface are obtained.
Example A2
Products Coated with Dark Chocolate—Application with Gum Arabic
[0272] Gum arabic solution (Capol 254, Capol GmbH) is mixed with 2-10% of interference pigment from Example 1. The non-glossy, chocolate-coated products are then introduced into a conventional coating pan. Between 5 g and 10 g/kg of the gum arabic solution are then applied over the products rotating in the pan to the products rotating in the pan. After a few minutes, drying air is directed over the products.
[0273] Chocolate dragees having a silver-white gloss on the surface are obtained.
Example A3
Sugar-Coated, White Chewing Gum—Film Coating
[0274] Preparation of the film coating solution:
[0275] 5% of HPMC film coating powder compound (Biogrund GmbH) are firstly mixed into 25% of ethanol (food grade, min 90% by vol.). 70% of cold water is then added. The mixture is stirred until the HPMC compound has completely dissolved.
[0276] 2-10% of interference pigment from Example 1 are then added to the solution prepared in this way.
[0277] The chewing gums are introduced into a coating pan and set in rotation. The coating pan here must be provided with suitable baffles. A two-component spray gun or spray system is positioned in front of the opening of the coating pan. The requisite drying air is switched on.
[0278] Depending on the desired colour effect, 30-80 g/kg of the film coating solution are applied to the chewing gums by means of the spray gun
[0279] White chewing gums having an additional, white gloss effect on the surface are obtained.
Example A4
Preparation of Hard Caramels
[0280]
TABLE-US-00001 Raw material % Sources of supply: Sugar 41% Südzucker Water 17.118% Glucose syrup 41% of C* Sweet Cerestar, Krefeld Interference pigment 0.082% (0.1% based from Example 1 on the casting composition) E 104 dil. 1:100 0.4% of Sikovit BASF, Ludwigshafen Flavour 0.4% (banana Dragaco, Holzminden 9/030388)
[0281] The sugar is heated to 100° C. with the water, and glucose syrup is then added. The solution is subsequently heated to 145° C. After addition of the interference pigment, the colour solution and the flavour, the caramel solution is poured into greased moulds using a funnel. Finally, the mixture is allowed to cool for two hours. The interference pigment can either be mixed with the sugar or added as a mixture with the glucose syrup. This variant contains no acid since the caramelisation would consequently be too strong.
[0282] Yellow, transparent hard caramels having an additional silver-white gloss effect in the product itself are obtained.
Example A5
Preparation of Gelatine Articles
[0283]
TABLE-US-00002 Raw material % Sources of supply: Water 10.48% Sugar 31.45% Südzucker Glucose syrup 31.45% Cerestar, Krefeld of C*Sweet Interference pigment 0.38% from Example 1 (0.4% based on the pouring composition) Citric acid dil. 1:1 2.51% Merck KGaA, Darmstadt Gelatine 7.86% DGF, Eberbach of 260 Bloom Water 15.748% Flavour 0.122% Dragoco, Holzminden (blackcurrant 9/695750)
[0284] Firstly, the gelatine is softened with double the amount of water at 60° C. Sugar and water are heated to 100° C., and the glucose syrup is then added. The mixture is heated further to 120° C. and then allow to cool to about 85° C. The interference pigment from Example 1, the citric acid, the flavour and the gelatine solution are stirred in, and the degassed gelatine mixture is filled into greased moulds using the funnel. The product is allow to cool for about 16 hours.
Further Embodiments
[0285] The interference pigment from Example 1 or Example 3 can again either already be mixed directly with the sugar or introduced with the glucose syrup. [0286] Instead of pouring into moulds, the traditional technique with negative moulds in moulding powder can also be used here for the production of gelatine articles.
[0287] White fruit-gum products having an additional silver-white gloss effect in the product are obtained.

[0290] This corresponds to 1.2 mg of polymer/cm.sup.2 of tablet surface
[0291] Preparation of the film coating solution: [0292] The interference pigment from Example 1 is stirred into water. Any additional dyes are subsequently added. Finally, the film former (HPMC) is scattered into the suspension. Due to the increasing viscosity, the stirring speed must also be increased accordingly. After about 40-60 minutes, the HPMC has completely dissolved and the solution can then be sprayed onto the tablets. [0293] The spray application is carried out by means of customary standard coating methods.
[0294] White tablets having a glossy white film coating on the surface are obtained.
Example A7
Tablets
[0295] Preparation:
[0296] The colouring of tablets is carried out by means of the so-called film coating process, in which aqueous application solutions (systems with film formers, plasticisers, etc.) are sprayed continuously onto the tablets rotating in so-called coaters.

Colouring of Wafers
[0580] Recipe and production process for all examples:
[0581] Composition:
[0582] 10 kg of wheat flour (type 405), 17 l of water (15° C.), interference pigments and further components as indicated in the examples;
[0583] percentages are % by weight and are based on the total weight of the dough.
[0584] Mixing: 15 min in a planetary stirrer
[0585] Baking: 1-3 minutes at 200/220.° C. in a plate wafer iron
Example A25.1
2% of Interference Pigment from Example 1
Example A25.2
4% of Interference Pigment from Example 1
Example A25.3
6% of Interference Pigment from Example 1
Example A25.4
8% of Interference Pigment from Example 1
[0586] On addition of 2% of interference pigment from Example A25.1, the interference colour is visible; very attractive gloss at 4% and 6%. An increase in the pigment concentration to 8% gives rise to only a slight improvement in the effect; slightly glittery effect.
Example A25.5
5% of Interference Pigment from Example 1+0.03% of Vegetable Black E153
[0587] The combination with the black pigment E153 (vegetable black E153 Fiorio Colori SA) enables various silver shades to be achieved; the intensity of the silver shade is adjusted via the addition of E153.
Example A25.6
5% of Interference Pigment from Example 1+0.02% of Carmine Red E120 (Fiorio Colori SA)
[0588] Wafers having a pink gloss are obtained.
Example A25.7
5% of Interference Pigment from Example 1+1% of Beetroot E160 (Chr. Hansen A/S)
[0589] Colour intensity of the beetroot concentrate after the baking process is reduced; slight brownish tinge; no effect on interference colour and gloss visible.
Example A25.8
5% of Interference Pigment from Example 1+0.8% of Flavour (Symrise GmbH)+0.5% of Aspartame Sweetener (Worlee GmbH)
[0590] The simultaneous use of the sweetener and flavour does not result in any impairment of the resultant gloss effect. The flavour and sweetener can easily and clearly be tasted.
Example A26
Colouring of Hard-Boiled Eggs
[0591] Application medium:
TABLE-US-00043 80% by weight of water 5.75% by weight of 1,2 propanediol E1520 Merck KGaA 2.4% by weight of sodium carboxymethylcellulose Roeper 1.5% by weight of soya or sunflower lecithin Sternchemie 0.3% by weight of citric acid (crystalline) Merck KGaA 0.05% by weight of potassium sorbate Merck KGaA 10% by weight of interference pigment from Example 2
[0592] Preparation of the application medium:
[0593] Water is initially introduced with potassium sorbate and citric acid, stirred using a paddle stirrer, and the mixture is heated to a maximum of 80° C. During the heating, sodium carboxymethylcellulose is added with constant stirring. Stirring is continued (about 45 min.) until all the cellulose has dissolved. Alternatively, the mixture can be stirred for 3 h without supply of heat:
[0594] As soon as all the sodium carboxymethylcellulose has dissolved in the water, 1,2-propanediol and lecithin are added at room temperature, and stirring is continued until all the ingredients have distributed uniformly. The amount of pigment indicated is subsequently stirred in.
[0595] Colouring:
[0596] Eggs are hard-boiled and subsequently coloured by means of an application medium according to the invention. To this end, a small amount of the medium is placed on a glove. A glove is also worn on the other hand. The boiled egg should be warm and dry. The application medium is distributed uniformly on the warm egg shell by rapid rubbing to and fro in the hands. Due to the residual heat of the egg, the application medium dries quickly. A very uniform pigment colouring is obtained. The eggs can have white or brown shells, depending on the interference pigment selected.
[0597] Different pigment amounts from 2-17% by weight lead to different intensities of the resultant gloss effect.
[0598] The colour does not penetrate through the egg shell.
Example A27
Colouring of Chocolate and Pralines
[0599] Prepared pralines, chocolates and chocolate-coated products in general can be decorated afterwards with the interference pigment application medium.
[0600] Application medium:
TABLE-US-00044 60% by weight of water 20% by weight of ethanol (96% by vol.) Merck KGaA 5.75% by weight of 1,2-propanediol E1520 Merck KGaA 2.4% by weight of sodium carboxymethylcellulose Roeper 1.5% by weight of soya or sunflower lecithin Sternchemie 0.3% by weight of citric acid (crystalline) Merck KGaA 0.05% by weight of potassium sorbate Merck KGaA 10% by weight of interference pigment from Example 1 + optionally sweetener and/or flavour as desired
[0601] Preparation of the application medium as in Example A26.
[0602] Colouring:
[0603] The application medium is applied to the chocolate product areas to be coloured by means of a fine nozzle, spatula or by means of a brush. Drying is then carried out at room temperature until the colour coating has completely dried.
[0604] The viscosity of the medium can be reduced by means of further addition of water. This enables the medium, if necessary, to be applied better to certain product areas. This increases the drying time.
Example A28
Pre-Colouring of Chocolate Moulds
[0605] Application medium:
TABLE-US-00045 80% by weight of water 10.75% by weight of 1,2 propanediol E1520 Merck KGaA 2.4% by weight of sodium carboxymethylcellulose Roeper 1.5% by weight of soya or sunflower lecithin Sternchemie 0.3% by weight of citric acid (crystalline) Merck KGaA 0.05% by weight of potassium sorbate + Merck KGaA interference pigment from Example 2 Merck KGaA
[0606] Preparation of the application medium:
[0607] The components are mixed as described in Example A26. Before addition of the interference pigment, a further 50% by weight of water are added, and stirring is continued until everything has distributed homogeneously
[0608] 5% by weight of interference pigment from Example 2 are added to this mixture.
[0609] Colouring:
[0610] Chocolate moulds made from plastic (for example polycarbonate) or metal can be pre-decorated very simply using the application medium according to the invention. The pigment-containing application medium is introduced into the mould at the desired points. The mould is subseuently dried in a fan-assisted oven or drying cabinet. The colouring of the mould can be carried out by suitable nozzles, pipettes, brushes or by hand.
[0611] The viscosity of the medium can be reduced by means of further addition of water. This enables the medium, if necessary, to be applied better to certain product areas. This increases the drying time.
[0612] Some of the water can optionally be replaced by ethanol (food grade 80-99.99% by vol.) in the preparation of the application medium. This accelerates the drying. 5-30% of the water can be replaced by ethanol.
Example A28.1:
[0613] It is furthermore possible to colour chocolate products uniformly by hand analogously to Example A26.
Example A29
Decoration of Marzipan or Fondant Articles
[0614] Analogously to the decoration of chocolate and pralines (Example A27), it is also possible subsequently to decorate other confectionery, such as, for example, marzipan or fondant articles, with the application medium according to the invention.
[0615] In contrast to chocolate and pralines, these products can be dried at elevated temperatures after the application.
[0616] Otherwise, the recipe variations, production processes and colouring possibilities are as described in Example A27.

[0622] Application medium:
TABLE-US-00047 10% by weight of interference pigment from Example 1 0.05% by weight of vegetable black CHR Hansen 89.95% by weight of application medium (base)
[0623] A total of 60 g (=15% of the amount of cereals) of application medium are applied little by little to the cereals rotating in the pan. 10 g of the application medium/application are applied. This is distributed over the cereals. Drying air is directed onto the cereals. As soon as an application has dried, a corresponding application amount can again be applied to the cereals, until the desired colour effect has been achieved. The cereals are subsequently dried, for example in a drying cabinet or oven, until the initial moisture is reached again.

Dragees (Chocolate, Sugar/Sugar-Free)
[0643] The application medium containing interference pigment is applied to the chocolate dragees rotating in the pan analogously to conventional coating by hand. Here too, layers are applied successively until the desired effect has been achieved. As soon as a layer has dried, a further addition can take place. A small application gives rise to a marble effect, while an increased application leads to a very uniform gloss colouring.

Further Surface Optimisation of Dragees
[0673] Both in the case of the chocolate-coated products (Examples A31.1-A31.3), and in the case of the sugar-coated or sugar-free-coated products (Examples A31.4-A31.6), the gloss and colour effect can be improved further if a mixture of shellac, ethanol and interference pigment is applied again after application of the application medium and a certain drying time. Ideally, this can be the interference pigment(s) already present in the medium, but other combinations are also possible. The shellac/ethanol/interference pigment mixture is applied by hand to the dragees rotating in the pan and dried by means of air. Alternatively, the mixture can also be sprayed.

Production of Decorative Lace and Decorative Sheets
[0703] Decorative lace is taken to mean filigree shapes and decorations produced by thinly spreading the first application medium in silicone moulds. After a certain drying time, these are removed from the moulds and can be used to decorate, for example, confectionery, ice cream, chocolate, eggs, pralines, bakery products, cakes and gateaux, desserts, pates, jelly loaves, or other foods. The drying time here can be adjusted so that the products still exhibit a certain elasticity.
[0704] It is also possible to use the decorations produced as edible body decorations. In this case, the decorations are applied to the corresponding body areas by means of suitable adhesives. When used as edible cosmetic, the paste can furthermore also be applied directly to body areas to be coloured. Body heat causes rapid drying on the skin.
[0705] Decorative sheets are taken to mean very thin, sheet-form structures produced by spreading the pigment medium very thinly on flat substrates. These substrates can consist, for example, a plastic or metal. After the spreading-out, the products are dried, for example in a drying cabinet or oven until completely dry. After drying, the decorative sheets can be removed from the substrates and can then be used as a whole, partly cut into small pieces or chopped correspondingly, for decoration of foods, as listed correspondingly, for example, in the case of the decorative lace described above.

Owing to the rapid increase in viscosity that occurs here, the stirrer speed must be adjusted in order to ensure good mixing. Flavours and sweeteners can also be added after the mixing of (A) and (B). The pH is subsequently adjusted to 3.5 using citric acid or buffer salts. Food dyes, interfere nce pigments (food grade), individually or in combination, are then stirred into this base composition.

[0752] The coloured base compositions of Examples A35.1a to A35.1 n are filled into negative moulds made from metal, plastic and silicone and dried for 8-12 h at 25° C. and then for 10-14 h at 40° C. either in a drying cabinet, air-conditioned drying room or oven. Depending on the air circulation or air humidity that can be set, the requisite drying time can be reduced correspondingly. An excessively high temperature at the beginning of drying leads to strong, less permeable film formation on the surface of the composition, meaning that further drying of the underlying composition is greatly retarded or even prevented.

[0758] Flavours and sweeteners can also be added after the mixing of (A) and (B). The pH is subsequently adjusted to about 3.5 using citric acid or buffer salts.
[0759] The interference pigment from Examples 1 to 3, individually or in combination, is then stirred into the base composition.
Example A36.3
Production of 3D Elements
[0760] 3D elements are produced by filling the finished base composition (see Example A36.1) into suitable moulds. Plastic or metal moulds, for example, as are also used analogously for the production of chocolate pralines or chocolate figures, marzipan figures, etc., are suitable here. Silicone moulds are less suitable owing to their worse heat conduction. The amount of 3D composition introduced depends on the viscosity and desired height of the 3D shapes and can be selected individually. However, it should be noted that more filling composition also means an extended drying time.
[0761] The filled moulds are then dried. It is important here that the drying process does not take place too quickly at excessively high temperatures, i.e. excessively high drying temperatures are not be selected in particular at the beginning of drying. In this case, the surface of the composition would dry out, preventing further moisture from escaping from deeper layers. This thus leads to partial drying-out of individual zones of the base composition, resulting in stresses within the composition, which lead to deformations and thus uneven drying-out of the base composition in the mould, with the consequence of irregular surface deformations.
[0762] Air inclusions can likewise no longer escape upwards and lead to flaws during drying. Low air humidity values support the drying in a positive manner here.
[0763] For this reason, the drying should begin slowly and at a low temperature—best overnight—over several hours, for example at room temperature 20-35° C., 24 h. If the composition has already very substantially adapted to the mould after the first drying phase (after about 6-10h), the final drying can be carried out at a higher temperature in a drying cabinet or drying room. Temperatures of 30 to 45° C. have proven successful here.
[0764] When the drying is complete, the finished 3D shapes can easily be removed by hand, or they fall out of the moulds by themselves. Chocolate, for example, can also be filled into the moulds analogously. After cooling, the now-decorated chocolate can be removed from the mould.
[0765] The more base composition is introduced, the longer the drying time lasts.
[0766] The drying is divided into a longer, first phase at (about room temperature −30° C.), and a second shorter drying phase at higher temperatures (about 30-40° C.). High air humidity extends the drying time, and should preferably be avoided.
[0767] Chocolate: the shapes produced in this way can be applied to finished chocolate products for decoration, or can also themselves be filled with chocolate. This can even take place in the mould itself.

Further use of the Base Composition
Example A36.4a
Films and Flakes
[0768] The ready-prepared base composition from Example A36.2 can alternatively also be spread out evenly over flat plastic or metal surfaces by means of a knife or spatula, etc. After subsequent drying, a thin layer is obtained which can either itself be used as a film for decorating foods or, divided into small pieces or shapes, can be applied as small flakes or decorations to foods of all types for decoration.
Example A36.4b
Direct Product Decoration
[0769] The finished base composition from Example A36.2 can also be used directly as such for decoration, for example for chocolate products. In this case, the 3D composition is applied thinly to the product areas to be coloured. After corresponding drying (see A36.3), decorated surfaces are obtained in which the composition has adapted precisely to the structure of the product surface. Apart from chocolate, other foods, such as, for example, cookies or cakes, can also be decorated simply and efficiently in this way. The drying time can be reduced by, for example, adding ethanol and/or reducing the amount of propanediol and/or the amount of Na carboxymethylcellulose.
Example A36.4c
Decorative Interlayers
[0770] Decorative stripes can also be produced in chocolate products. This is carried out by, for example, first filling the mould with a little warm chocolate, allowing this to cool, and subsequently adding the base composition in a thin layer over the chocolate. After the obligatory drying time, the mould can be filled with a further layer of warm chocolate. After cooling of the second chocolate layer, this thus gives a chocolate figure with a coloured intermediate decorative stripe. This is visible very well on the side of the chocolate figure.

Vegan Bread Spread
[0773] 640 g of smoked tofu*
[0774] 150 g of kidney beans (can, drained)*
[0775] 150 g of sunflower or rapeseed oil*
[0776] 30 g of roasted onions*
[0777] 5 g of paprika powder, smoked*
[0778] Herbs: marjoram, oregano*
[0779] Salt, pepper*
[0780] 10-20 g of interference pigment from Example 3 (1-2%), depending on the desired colouration
[0781] All *ingredients are finely ground by means of a Turrax/hand blender to give a puree.
[0782] The interference pigment is then added and stirred uniformly into the product.
[0783] The vegan spread can subsequently be stored in the refrigerator (about 1 week), or heated at 100° C. for 20 minutes in a suitable, sealed container. It must be noted here that in this case the proportion of herbs may have to be adjusted. Storage in the sealed container at room temperature is then possible over an extended period.
[0784] Due to the very good heat stability of the interference pigments, no loss in colour occurs here
