The present invention relates to a microencapsulate comprising microcapsules having a diameter of 0.1 µm to 25 μm, said microcapsules comprising: -a core particle having a diameter of 90 nm to 23 μm and containing at least 3% of the active component by weight of said core particle and -a coating that fully envelops the core particle and containing at least 20 wt.% of a hydrophobic polymer selected from cellulosic ethers, cellulosic esters, zein, shellac, gluten, polylactide, hydrophobic starch derivatives,polyvinyl acetate polymers, polymers or copolymers derived from an acrylic acid ester and/or a methacrylic acid ester and combinations thereof wherein the core particle contains a release trigger component and/or the coating contains a release trigger component, said release trigger component being selected from: -a water-swellable polymer having a water-uptake capacity at 37 ºC and pH 7.0 of less than 20 wt.% and a water-uptake capacity at 37 ºC and pH 2.0 of at least 50 wt.% and -an edible salt having a water solubility at 37 ºC and a pH of 7.0 of less than 1 mg/ml and a water solubility at 37 ºC and a pH of 2.0 of at least 5mg/ml The microencapsulate of the present invention does not release the encapsulated active component when incorporated in water-containing foodstuffs, beverages,nutritional compositions or pharmaceutical compositions. Following ingestion, however, the active component is released rapidly.La présente invention porte sur un produit microencapsulé comprenant des microcapsules présentant un diamètre de 0,1 µm à 25 µm, lesdites microcapsules comprenant : une particule centrale présentant un diamètre de 90 nm à 23 µm et contenant au moins 3 % du composant actif en poids de ladite particule centrale et un revêtement qui enveloppe entièrement la particule centrale et contenant au moins 20 % en poids dun polymère hydrophobe choisi parmi les éthers cellulosiques, les esters cellulosiques, la zéine, la gomme laque, le gluten, le polylactide, des dériv
