摘要:
The present invention provides a method of producing α-santalene by contacting at least one polypeptide with farnesyl phyrophosphate (fpp). In particular, the method may be carried out in vitro or in vivo to produce α-santalene, a very useful compound in the fields of perfumery and flavoring. The present invention also provides the amino acid sequence of a polypeptide useful in the method of the invention. A nucleic acid encoding the polypeptide of the invention and an expression vector containing the nucleic acid represent part of the present invention. A non-human host organism and a cell transformed to be used in the method of producing α-santalene are also part of the present invention.

Citrus washed oil flavors can be formulated by a process which comprises treating a citrus oil with a mixture of propylene glycol and an alkanol from C1 to C4. The resulting washed oil flavors can be used as flavoring ingredients, notably for clear beverages.
摘要:
The present invention relates to a process for producing perfume-containing microcapsules with a polyurea wall that can be used in home or personal care products, as well as to the microcapsules themselves and consumer products comprising these microcapsules. The process of the invention uses a particular colloidal stabilizer in the form of an aqueous solution comprising defined proportions of particular polymers.
摘要:
The present invention provides a method of producing sclareol, said method comprising a) contacting a particular polypeptide having a LPP synthase activity with GGPP and b) contacting a particular polypeptide having a sclareol synthase activity with labdenediol diphosphate (LPP) produced in step a). In particular, said method may be carried out in vitro or in vivo to produce sclareol, a very useful compound in the fields of perfumery and flavoring. The present invention also provides the amino acid sequence of the polypeptides used in the method. Nucleic acids derived from Salvia sclarea and encoding the polypeptides of the invention, expression vectors containing said nucleic acids, as well as a non-human host organism or a cell transformed to harbor the same nucleic acids, are also part of the present invention.
摘要:
The invention relates to a process for preparing microcapsules by coacervation, wherein the cross-linking of a protein is carried out by a plant extract rich in substituted or unsubstituted phenolic compounds.

摘要:
The present invention relates to transformed plants with an altered terpene content, preferably over-accumulating a mono- and/or sesquiterpene. By transformation of plants with genes ancoding terpene synthases (TS), and prenyl transferases (PRT), plants accumulating at least 1000 ng / per g of fresh leaf of a specific terpene were obtained. The present invention provides an advantageous system for production of terpenes in that any desired mono- and/or sesqui- terpene at the choice of the skilled person can be produced in plants. Preferably, the transformed plants contain at least one recombinant plastid targeted TS and PRT.
