Description

DESCRIPTION OF THE INVENTION

[0014] It has been found that hard, preferably moulded candies, which are white or multicoloured with at least one white portion, can be advantageously obtained without the use of titanium dioxide. The hard candies obtained according to the invention do not contain crystallised sugars or other crystallised ingredients, and are preferably in a totally amorphous state. The candies obtained according to the invention are preferably characterised by a residual water content ranging from 0.5% to 5%, preferably from 0.7% to 3%, most preferably from 1.2% to 2.7% by weight of the finished candy.

[0015] The preferred forms of embodiment are in overlaid layers or segments (also known as swirls), wherein white portions alternate with portions of other colours.

[0016] Another form of embodiment involves the insertion of a stick to obtain a lollipop, the edible part whereof is as described above.

[0017] It has been found that in order to obtain the characteristic of a bright, opaque white colour in confectionery products without generating yellowing of the white portion in the process, it is necessary to operate, during the mass cooking step, under lower temperature and higher negative pressure conditions than the standard ones described in the prior art.

[0018] It has also been found that condensed milk can be advantageously used as a replacement for titanium dioxide in confectionery products, in particular hard candies, which are white or multicoloured with at least one white portion. The object of the invention, in a first aspect thereof, is a process for the production of confectionery products, in particular hard candies, containing neither crystallised ingredients nor titanium dioxide, said candies being white or multicoloured, with at least one white portion, which comprises the following steps: [0019] preparing a first liquid mixture of ingredients containing condensed milk and optionally animal and/or vegetable fats selected from butter, vegetable oils, hydrogenated vegetable oils, cocoa butter, lard, ghee, cream and powdered milk, [0020] preparing a second liquid mixture in the form of an aqueous solution comprising at least sugar and glucose syrup, either alone or combined with one another, preferably at a temperature below 130 C.; [0021] mixing the first mixture and the second mixture, preferably in a ratio of 1:100 to 1:1, more preferably 1:50 to 1:10, most preferably from 1:40 to 1:15; [0022] transferring the resulting mass into a vacuum cooker and cooking the candy mass at a pressure ranging from 0.20 to 0.5 bars, preferably from 0.3 to 0.4 bars, most preferably from 0.2 to 0.35 bars, relative to atmospheric pressure, and at a temperature ranging from 130 C. to 139 C., preferably from 131 C. to 138 C.

[0023] The cooked mass is then poured into moulds of the chosen shape and, after cooling and extraction from the moulds, the resulting candies are conveyed to the packaging unit.

[0024] In the process according to the invention, an aqueous solution comprising one or more of the following is preferably added to the first mixture: sodium chloride, sodium bicarbonate, lecithin and maltodextrin.

[0025] The vacuum cooker is preferably the microfilm type, used according to the prior art.

[0026] The process according to the invention can also include the following steps: [0027] dividing the mass of candy after cooking into one or more streams and conveying each of said streams to one or more static mixers wherein at least one flavouring, colouring or additive is added, on the proviso that the colourings do not contain white pigments; [0028] placing the one or more resulting candy masses in heated hoppers; [0029] pouring the one or more masses from the hoppers into moulds to obtain individual candies characterised by one or more white regions.

[0030] The candy masses are preferably maintained in the hoppers at temperatures sufficient to keep the mass at a suitable level of fluidity for the subsequent pouring; said temperatures are preferably lower than 139 C., most preferably lower than 135 C.

[0031] FIG. 1 contains the flow chart of the process according to the invention by way of example.

[0032] A further object of the invention is the use of condensed milk as a replacement additive for titanium dioxide in confectionery products having at least one white portion.

[0033] A further object of the invention consists of hard candies which are white or multicoloured with at least one white portion, characterised by a percentage of condensed milk ranging from 0.5% to 5% by weight of the total candy, and by the absence of titanium dioxide and crystallised ingredients.

[0034] Condensed milk means a form of milk rendered storable by removing about 60% of its water content, typically by low-pressure evaporation. Condensed milk is available on the market or can be prepared by known methods, including by reconstitution from powdered milk. The condensed milk is preferably used in a percentage ranging from 0.5% to 1.2% by weight of the total candy.

[0035] The ingredients of the confectionery product are conventional, and typically include sucrose, glucose syrup, polyols, cream, hydrogenated oils or fats, salt, flavourings and flavour enhancers, emulsifiers, acidifiers and colourings.

[0036] In particular, the candies according to the invention contain sugar, glucose syrup and animal and/or vegetable fats. The fats are preferably contained in a ratio of 1% to 50%, preferably 1.5% to 20%, most preferably 2% to 10% by weight of the total candy.

[0037] The test for the degree of whiteness and opacity of the candies made according to the invention, compared with the degree of whiteness and opacity of candies with titanium dioxide made by the conventional process, was conducted with a portable X-Rite spectrophotometer equipped with sphere reflection geometry for the determination of the coordinates L*a*b.

[0038] The candies of the invention are therefore characterised, in the white areas, by the following parameters: L from 55 to 90, a from 3 to +3, and b from 15 to 3. Candies characterised by L from 68 to 79, a from 2 to +2 and b from 17 to 7 are particularly preferred.

[0039] The process according to the invention is illustrated in detail in Example 1 below.

Example 1

[0040] Preparation of a hard candy having the following composition:

[0041] Composition of White Mass

TABLE-US-00001 Ingredients % Sugar 50 Glucose syrup 37 Condensed milk 1 Cream 1 Hydrogenated vegetable oil 6 Salt 0.2 Lecithin 0.3 Acidifiers 1 Flavourings 0.5 Residual water 3 Total 100

[0042] Composition of Red Mass

TABLE-US-00002 Ingredients % Sugar 50 Glucose syrup 37 Condensed milk 1 Cream 1 Hydrogenated vegetable oil 6 Salt 0.2 Lecithin 0.3 Acidifiers 1 Flavourings 0.5 Residual water 3 Allura Red 0.005 Total 100

[0043] The hot water, sodium chloride salt, sodium bicarbonate, condensed milk and maltodextrins are mixed in a tank heated to a maximum temperature of 60 C. for 15 minutes. Lecithin is then added, and the mass is mixed at the same temperature for a further 5 minutes.

[0044] The hydrogenated vegetable oils and cream are added, and the resulting mixture is stirred for 20 minutes at a maximum temperature of 55 C.

[0045] A liquid mixture of water, sugar and glucose syrup is prepared in a separate tank, and pre-cooked at 125 C.

[0046] The first mixture, containing fats, and the liquid mixture, containing sugar, are conveyed to a collection tank, where other ingredients may be added.

[0047] The mass is then transferred to a microfilm cooker operating at a temperature not exceeding 139 C. and a negative pressure not exceeding 0.5 bars relative to atmospheric pressure for about 15 seconds.

[0048] The mass is divided into two streams; flavouring is added to each one in static mixers, and Allura Red colouring is added to one of the two streams. The two completed masses are then inserted in two separate, heated hoppers of a depositing machine. Candies with alternating white and red segments are then poured into teflon-coated steel moulds. Pouring into the moulds is followed by cooling, removal of the candies from the moulds, and packaging of the end product.

[0049] FIG. 1 is a flow chart of the process exemplified.
