Abstract

Shaped articles containing plant extract(s), in particular pellets, are formed by dispersing the plant extract(s) in a matrix predominantly composed of a skeleton builder, i.e. collagen, gelatin, fractionated gelatin, a collagen hydrolysate, a gelatin derivative, plant protein or plant protein hydrolysate. They are storage-stable, and their pharmacological and cosmetic characteristics are essentially unaltered in comparison with the native extract. They are prepared by a simple process in which liquid plant extract(s) is(are) mixed or emulsified in a solution of the skeleton builder, or solid extracts are dissolved or suspended in a solution of the skeleton builder, the dispersion of skeleton builder and plant extract(s) is added dropwise to an intensely cold, inert, liquefied gas, preferably liquid nitrogen, thus shaping the pellets, and the shaped pellets are dried. The plant extract employed is preferably Aloe vera juice.
