Abstract

FIELD: food-processing industry.

SUBSTANCE: method involves pressing non-colored mass formed as granulate of basic composition; coloring said mass by adding into mass under pressing process of granulate colored in one or several colors, with intensity and nature of coloring of said pressed composition being controlled by regulating amount of colored granulate introduced into mass. Colored granulate is volumetrically colored granulate or surface colored granulate or colored micropellets , i.e., nonpareil.

EFFECT: wider range of coloring forms or textures of solid compositions and minimized amount of colorants consumed.

Description

The invention relates to the food and pharmaceutical industries, and in particular to the technology of coloring food and pharmaceutical forms of products produced by pressing (tablets, briquettes, pressed dragees).

Currently, more and more pharmaceutical and food products (biologically active additives (BAA), confectionery) produced by pressing are appearing on the consumer market. With the increase in assortment, the problem arises of visual identification of products by the end user. Situations may arise when one consumer or his family simultaneously uses several products that are similar in appearance. There is a problem of erroneous reception of products. The solution to the problem can be the expansion of the painting range of pressed compositions.

Currently, for example, there are several types of diabetic products of the same type that use different types of sweeteners, such as xylitol, sorbitol, fructose, etc. It is important for the consumer to know which sweetener is used, because There are different rules for the consumption of each of them. In some cases, the manufacturer indicates the name of the sweetener on the package, but such an inscription can be printed in small print (often in people with diabetes, vision is impaired). Therefore, the possibility of specific coloring of products for various purposes, quality or composition will serve to increase their consumer properties.

A known method of coloring pharmaceutical preparations, implemented in a pharmaceutical composition with an enteric coating for oral administration, in which the core material of the active ingredient is coated with one or more layers of an enteric coating, into which dyes can be incorporated (see RF patent No. 2138254, MKI A 61 K 9/24, 1999). The main disadvantage of this method is the need to apply an additional uniform color coating to the tablet, which makes production more expensive, and the color variety is limited by the color scheme of visually distinguishable pigments.

A known method of manufacturing solid pharmaceutical forms (see RF patent No. 2076700, MKI A 61 K 9/22, 1997), comprising obtaining a moistened mass in the form of a mixture of ingredients with a coloring agent, granulating it and then compressing it into tablet form. The disadvantage of this method is also a limited set of colors if necessary, the introduction of the entire initial mass of a significant amount of a coloring agent. Almost all food coloring agents used in the pharmaceutical and food industries are not biologically indifferent, therefore, their use is limited. The disadvantage of this method is even more pronounced in confectionery products obtained by pressing. A single consumption of dye in the confectionery product can reach large values and exceed the maximum permissible rate.

An object of the present invention is to remedy the aforementioned drawbacks, namely, to obtain a wide range of paint forms (textures) of solid compositions while minimizing the mass of dyes used.

This problem is solved by adding to the unpainted granular pressed mass the main composition of the composition of the colored granulate, while the intensity and color character of the pressed composition is controlled by the amount of the added colored granulate of one or more colors. When using colored granules, painted only on the surface, the consumption of dyes is significantly reduced to achieve the same decorative effect.

The proposed method allows to provide the color of the composition in any color, and also, in the case of using a sufficiently large granulate (particle diameter 0.5-2 mm) and staining it in different colors, to provide the opportunity to obtain a variegated color surface texture. The nature of the color composition of the texture is determined by the size and color diversity of the granulate, as well as by the quantitative ratio of granules of different colors in the mixture of granules prepared for pressing.

In the case where the pigment is an active principle, for example, carotene (E-160a dye) or betaine (E-162 dye), volumetric colored granulate can be used in the production of dietary supplements or sweets.

To reduce the amount of dye introduced, the granulate is stained by surface staining (by spraying the dye in a fluidized bed (granulate) or pelleting drum).

As a granulate to obtain a spotted texture, a surface-dyed microdrage (nonpareil) can be used.

The described method of coloring allows you to get a wide range of color textures on the surface of solid pressed compositions using a minimum number of dyes, which has no analogues among the methods of painting solid pressed food or pharmaceutical compositions, and therefore meets the criterion of "inventive step".

In more detail, the implementation of the proposed method is explained in the following examples.

Example 1. Consider a method for uniform volumetric coloring of a solid pressed composition. The colored granulate is added to the bulk of the white granulate. For coloring the granulate, you can use powders from sea buckthorn cake, dried blueberries, aronia, lingonberries or other intensely colored berries, vegetables (carrots, beets) or fruits. The colored granulate is uniformly mixed with unpainted and subjected to conventional pressing.

Example 2. Consider a method of uneven, colorful, dyeing a solid pressed composition. Unpainted, white, microdrazh (nonparel) is separately painted in the coating drum in the primary colors of the rainbow by introducing the dye into the surface layer at the final stage of drazhirovany. Then separately stained microdrags are thoroughly mixed and pressed.

Example 3. A method of manufacturing jelly beans "Jolly Rogers" (the romantic name for the pirate flag). Sugar crystals, used as a body, are coated with a sugar-syrup syrup and icing sugar in a coating drum with a knurling layer up to a microdrage with a diameter of 1.5-2 mm. Preliminarily, menthol in an amount of 0.5%, rum flavor - 0.2% and citric acid - 0.5% are introduced into sugar-syrup syrup. The resulting microdrags are divided into two parts in a ratio of 1/3. Most of the dragee is stained with black dye E-152 in the coating drum by introducing dye instead of icing sugar at the final stage of dragee in the amount of 1% of the total weight of the dragee. Painted and unpainted dragees are dried in a drying chamber to a moisture content of 4%, thoroughly mixed and pressed using a rotary tablet press into spherical tablets. The dragee coloring imitates the basic colors of the pirate flag (black and white), and when packed in boxes with pirate symbols, it opens a romantic series.

Thus, the claimed method allows to obtain reproducible one-color or multi-colored (variegated) coloring of dragees, briquettes or tablets produced by pressing with the simultaneous possibility of a significant reduction in the consumption of food colors.

In the food industry, the proposed method for coloring pressed pellets and briquettes opens up a new direction in the aesthetic design of finished products.

In the pharmaceutical industry, it is possible to obtain a wide range of paint forms, which can serve as an additional means of visual identification of drugs for consumers.
