Definitions
- TITLE A composition comprising chlorophyllin as a green pigment
- the present invention relates to a green coloring composition comprising copper chlorophyllin as a green pigment. It may be used in the manufacture of food and pharmaceutical products.
- Copper chlorophyllin is today used commercially as a green pigment in different food products.
- C-10.000P-WS-AP The commercially available acid stable (e.g . in soft drink) transparent natural green color product of Chr. Hansen A/S, Denmark termed "C-10.000P-WS-AP" comprises following ingredients: Sodium copper chlorophyllin (E 141(ii)), propylene glycol (E 1520) (69%), polysorbate 80 (E 433) (23%) - see e.g . the publicly available product information.
- this natural green C-10.000P-WS-AP product is used in e.g . soft drinks (low pH around 3-4) a stable transparent green color is obtained .
- chlorophyllin (green color) particles are very small in the suspension - i.e. very small chlorophyllin (green color) particles dispersed in the low pH water phase (e.g . soft drink).
- Polysorbate 80 (Tween 80) is a detergent/emulsifier - herein alternatively expressed dispersing agent.
- Polysorbate 80 (Tween 80) may be said to have an unwanted unpleasant taste.
- CapColors®Green 100 Another natural green color product of Chr. Hansen A/S, Denmark is termed CapColors®Green 100 and it may be characterized as made by milling in order to create sufficient small chlorophyllin (green color) particles. According to the public available product information - for this product the color will look more or less opaque (i.e. one may say that it is less transparent than the C-10.000P-WS-AP product discussed above).
- CapColors®Green product does not comprise Polysorbate 80 and may therefore be seen as a prior art solution to make a product without the unpleasant taste of Polysorbate 80 (Tween 80).
- the compound quillaja is a known detergent/emulsifier.
- WO2011/119290A1 and WO2011/154407A1 describe use of quillaja as emulsi- fier in an oil-in-water emulsion.
- Claim 14 of WO2011/154407A1 relates to an oil-in-water emulsion comprising chlorophyll.
- chlorophyll is soluble in oil/fat and not in water at any herein relevant pH range.
- the herein relevant copper chlorophyllin green pigment is not soluble in oil/fat.
- the problem to be solved by the present invention is to provide a green color- ing composition, giving a green transparent color in acid applications, comprising copper chlorophyllin as a green pigment, wherein the green coloring composition does not have a herein relevant unwanted unpleasant taste (i.e. is not comprising significant amounts of Polysorbate 80 (Tween 80)).
- the solution is based on the fact that the present inventors has identified that a water-dispersible composition using quillaja as dispergent agent is very good in relation to use of copper chlorophyllin as a green pigment - see working examples herein for further details.
- An advantage of quillaja is that it does not have a herein relevant unwanted unpleasant taste (i.e. like Polysorbate 80 (Tween 80)).
- Polyglycerol and quillaja have both a relatively high Hydrophilic-lipophilic balance (HLB) value - however, even though Polyglycerol has a relatively high HLB value it is not working properly in the present context.
- HLB Hydrophilic-lipophilic balance
- a first aspect of the invention relates to a water-dispersible green composition
- a water-dispersible green composition comprising from 0.5% to 70% (w/w on a water free basis) of copper chlorophyllin as a green pigment and from 1.0% to 80% (w/w on a water free basis) of quillaja.
- composition of the first aspect is shown in working Example 1 herein - wherein the composition comprises 8.2% (w/w on a water free basis) of copper chlorophyllin and 26.2% (w/w on a water free basis) of quillaja.
- Example 1 The rest of the material/substance of the composition/suspension of Example 1 herein was Propylene glycol : 65.6% (w/w on a water free basis) and around 50-52% water.
- the water-dispersible green composition of the first aspect comprises less than 90% (w/w) of water.
- water-dispersible composition as described herein may advantageously be used for green coloring of a herein relevant edible, drinkable or pharmaceutical product - such as in particular a product with a herein relevant not alkaline pH value.
- a stable transparent green solid-in-water dispersion product e.g . a soft drink or a wine gum product
- a stable transparent green soft drink product was made.
- a second aspect of the invention relates to a transparent green solid-in-water dispersion product comprising copper chlorophyllin particles as a green pigment and quillaja as dispergent agent and wherein the pH of the dispersion is from pH 1 to pH 8 and wherein the ratio (w/w) of copper chlorophyl- lin and quillaja is a ratio from 0.01 to 10.
- a third aspect of the invention relates to a method for preparing the water- dispersible composition of the first aspect, wherein method comprises the following steps:
- a fourth aspect of the invention relates to a method for making a transparent green solid-in-water dispersion product of the second aspect, wherein the method comprises dispersing the water-dispersible composition of the first aspect into a water based product with a pH 1 to pH 8 to thereby obtain the transparent green solid-in-water dispersion product of the second aspect.
- a fifth aspect of the invention relates use of the water-dispersible composition as described herein to green coloring of an edible, a drinkable or a pharmaceutical product.
