Definitions

  • the present invention relates to a black oil-based suspension, comprising carbo vegetabilis as a black pigment.
  • the oil-based suspension may be used as a coloring agent in the manufacture of e.g. food products and pharmaceutical products.
  • Coloring agents containing natural or synthetic coloring substances are commonly used as additives in the manufacturing of food products and pharmaceutical products.
  • a wide range of such coloring agents is commercially available making it possible for the manufacturer, where a particular color tone is desired, to select a single coloring agent having the desired color or a mixture of coloring agents which in an appropriate combination impart the desired color to the product.
  • the commercially available coloring agents can contain synthetic substances including substances that are also normally referred to as dyes or azodyes, or such agents can contain pigments or other coloring substances of natural origin, e.g. in the form of plant material containing a coloring substance, or as more or less purified coloring substances separated from plant, animal or microbial materials naturally containing such substances.
  • coloring substances covering all color tones and also for improving any desired property of a particular color substance.
  • One particular color which is not commonly found in nature, is the color black.
  • a source for obtaining a coloring substance providing a black color to e.g. food or pharmaceutical products is "carbo vegetabilis". This pigment substance is produced by the carbonization of vegetable material.
  • carbo vegetabilis also called vegetable carbon, E 153
  • E 153 is a pigment in the form of a dusty powder.
  • Carbo vegetabilis has a high surface-area- to-volume ratio and provides an intense black color.
  • Carbo vegetabilis is, in its pure form, a very light fine black powder which is extremely difficult to handle in industrial settings e.g. production of food or confectionary. It is easily spread by currents in the air and is very difficult to clean off surfaces, as it is very hydrophobic and not soluble in any normal cleaning agents, including acids, alkalis and organic solvents.
  • carbo vegetabilis When mixed in a liquid, carbo vegetabilis has a tendency to agglomerate, and form sediments.
  • coloring substances containing carbo vegetabilis are produced by dispersing the pigment powder in glucose syrups or solutions of cellulose derivatives, thus, obtaining an paste which can be used "as is” or which can be processed to provide a further coloring composition.
  • Commercially-available substances comprising carbo vegetabilis are not well suited for all applications particularly due to either:
  • RU 2548964 discloses a food coloring using vegetable coal in a water-soluble system.
  • One object of the present technology is therefore to provide a form of carbo vegetabilis which is suitable for industrial handling in e.g. food or pharmaceutical applications.
  • the technology should provide an oil-miscible form of carbo vegetabilis, so that it can be used as a component of e.g. fat-containing foods.
  • the suspension should not agglomerate or sediment over time.
  • the dye suspension should provide an intense dark shade, which does not have "off" notes (smell or taste).
  • the suspension should also be heat and oxidation stable.
  • the present invention relates to an oil-based suspension for coloring of food or pharmaceutical products, said oil-based suspension comprising: carbo vegetabilis particles; at least one emulsifier; at least one vegetable oil; wherein the carbo vegetabilis particles are dispersed in said vegetable oil.
  • a method for producing the oil-based suspension described herein comprising the steps of: a. dispersing the at least one emulsifier in the at least one vegetable oil to provide a vegetable oil dispersion; b. adding the carbo vegetabilis pigment to the vegetable oil dispersion, and mixing said dispersion; thereby providing the oil-based suspension according to the invention.
  • the at least one emulsifier may comprise a C4-C28 fatty acid monoglyceride or diglyceride or derivative thereof.
  • the at least one emulsifier may comprise a C4-C6 organic acid ester of a C4-C28 fatty acid monoglyceride or diglyceride.
  • Particular emulsifiers of interest are citric acid esters of mono and diglycerides of fatty acids (E472c, Lecithin E322, Mono- And Diglycerides Of Fatty Acids E 471, Sorbitan monooleate E494 and diacetyl tartaric acid ester of mono- and diglycerides (E472e).
  • Particularly preferred is DATEM.
  • These emulsifiers have the correct hydrophilic-lipophilic balance (HLB) and dispersive effects for suspension of carbo vegetabilis in oil.
  • the at least one emulsifier is not derived from palm oil.

Abstract

L'invention concerne une suspension à base d'huile noire, comprenant du charbon végétal en tant que pigment noir et en outre au moins un émulsifiant et au moins une huile végétale ; et un procédé de production de la suspension à base d'huile comprenant la dispersion de l'au moins un émulsifiant dans l'au moins une huile végétale pour obtenir une dispersion d'huile végétale et l'ajout du pigment de charbon végétal à la dispersion d'huile végétale et le mélange de ladite dispersion. La suspension à base d'huile peut être utilisée comme agent colorant dans la fabrication, par exemple, de produits alimentaires et de produits pharmaceutiques.
