Abstract
Disclosed is method for the preparation of an amylose/carotenoid complex including the steps of a) heating a first composition in powder form including amylose or one of its derivatives, so that this amylose changes to amorphous form; and b) mixing the first composition obtained at the end of step a) with a second composition in powder form including at least one carotenoid-type pigment so as to enable the heating of the mixture between 30 and 70° C. to allow the passage to the V conformation of the amylose or one of its derivatives during the complexation of the latter with the carotenoid type pigment, until a homogeneous powders mixture is obtained; compositions which can be obtained by such a method as well as the use of such compositions in the fields of printing, writing, tattooing or make-up.
Claims13
A method for the preparation of an amylose/carotenoid complex, said amylose/carotenoid complex consisting of 1) one carotenoid-pigment and of 2) amylose or a derivative of amylose, said method comprising:
- a) heating a first composition in powder form comprising amylose or a derivative of amylose, so that this amylose changes to amorphous form;
- and
- b) mixing the first composition obtained at the end of step a) with a second composition in powder form comprising at least one carotenoid pigment, where the mixture is heated between 30° and 70° C. to allow the passage to the V conformation of the amylose or a derivative of amylose during complexation of the amylose or a derivative of amylose with the carotenoid pigment, until a homogeneous powders mixture is obtained, whose mixture is a solid composition having a homogenous color said homogeneous color being due to complexation of the carotenoid pigment with amylose with less than 10% carotenoid pigment in non-complexed form together with less than 10% of said at least one carotenoid pigment in degraded form.
