Abstract
Plant extract containing pellets are formed by a dispersion of plant extract or extracts in a matrix, principally comprising a skeleton builder namely collagen, gelatin, fractionated gelatin, a collagen hydrolysate, gelatin derivative plant proteins, or plant protein hydrolysates. They are shelf stable and their pharmacological as well as cosmetic properties are substantially unchanged in comparison to the native extracts. They may be produced by a simple process in which a solution of the skeleton former is mixed with liquid plant extract or emulsified with solid extracts, dissolved or suspended, the dispersion of the skeleton former and the plant extract dropped into a very cold inert fluid, suitably liquid nitrogen, to form the pellets and the thus formed pellets dried.
