| 摘要 |
<p>The invention relates to a method for obtaining an active ingredient with anti-wrinkle and firming properties, characterised in comprising the production of two products A and B from soya, said two products being obtained by the series of the following steps: Product A - solubilisation of a soya filter cake at a rate of at least 50 g/l by weight, in water at an acidic pH, simultaneous or successive enzymatic hydrolyses in the presence of proteases, filtration, decantation or centrifugation to separate the solubilised phase from the insoluble products and successive concentrations of the active phase by filtration, ultrafiltration, osmosis or nanofiltration, Product B - solubilisation of soya fibres in water at a basic pH, at least one enzymatic hydrolysis by means of at least one protease, filtration, decantation or centrifugation to separate the solubilised phase and the insoluble products and successive concentrations of the active phase by filtration, ultrafiltration, osmosis or nanofiltration and mixing of said two products A and B. The invention further relates to the uses thereof and the compositions including said active ingredient.</p> |
