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.
Plant extract containing dried cryopellets comprising a plant extract the activity and amount whereof is essentially undiminished by the cryopelleting dispersed in a matrix at least 50% w/w whereof comprising substantially of skeleton forming water soluble hydrophilic macromolecular material selected from the group consisting of collagen, scleroproteins, gelatin, fractionated gelatin, collagen hydrolysates, succinylated gelatin, elastin hydrolysates, plant proteins, plant protein hydrolysates and mixtures thereof.
Process for the preparation of a plant extract containing dried cryopellet having a matrix, the amount and activity of said extract being essentially undiminished by the cryopelleting, comprising the steps of:
