METHOD AND COMPOSITION FOR PRODUCTION OF DRY LYOPHILIZED FORMS OF ANTHOCYANINS Russian patent published in 2017 - IPC A61K31/352 A61K47/36 A23L19/00 C09B61/00 

FIELD: biotechnology.

SUBSTANCE: anthocyanin extract obtained from petals of a red curb rose, or chokeberry fruit, or nasturtium petals, purified by the sorption-desorption method using a sorbent is added to a polysaccharide matrix selected from agar-agar or maltodextrin, or arabinogalactan or carrageenan, at the following weight ratio: purified anthocyanins extract:polysaccharide matrix from 1:100 to 1:200, the mixture is stirred until a homogeneous mass is obtained, the resulting sample is frozen at a temperature of minus 18-20°C for at least 48 hours, after which lyophilization is carried out for 8-10 hours at a temperature of minus 50°C and a pressure of 0.1 mBar. The invention also relates to a composition for dry lyophilized forms of anthocyanins production by this method.

EFFECT: production of dry forms of anthocyanins, readily soluble in water and having good preservation for at least six months, reduced loss of anthocyanins in the process of obtaining of a lyophilized form.
