摘要:
The present invention relates to a heteropolysaccharide (HP) characterized in that it can be obtained by fermentation of a medium comprising at least one strain of Pseudomonas sp I-2054 (or DSM 12295), one of the recombinants thereof or the mutants thereof and a source of carbon which can be assimilated by said strain, one of the recombinants thereof or one of the mutants thereof. The invention also relates to a method for the production and use of said heteropolysaccharide as a thickening agent and/or gelling agent.
摘要:
Fluorescent latices, well suited for a wide variety of analytical techniques, comprise polymer particles having at least one hydrophobic fluorochrome encapsulated therein, notably at least one condensed polyaromatic compound or derivative thereof, or a tetraphenylporphine and/or organometallic complex thereof, and have a detection threshold for fluorescence which is less than or equal to 10.sup.-12 mol of particles per liter of latex.
摘要:
Latices of monodisperse magnetizable microspheres contain a hydrophobic polymer matrix and magnetizable fillers. The microspheres have a calibrated particle-size distribution and a size of around 0.1-5 micrometers, and the polymer matrix, produced by a dispersion polymerization method, includes polymer chains derived from at least one vinyl monomer. The latices are useful in biology, in particular, for diagnostic and affinity chromatography methods.
摘要:
Graft polysaccharides comprising a polymer backbone consisting essentially of a polydextrose having an average-weight molecular mass of less than 10,000 and grafts grafted thereon derived from a water-soluble ethylenically unsaturated monomer. The graft polysaccharides are useful as sequestering agents for alkaline-earth metal ions.
摘要:
The invention concerns a gum carob with average mole weight (Mw) ranging between 2.5.105 and 1.5.106 g/mol and whereof at least 60 wt. % of said gum is soluble in an aqueous medium at a temperature not higher than 60° C.
摘要:
A fluorescent latex with particles containing at least one encapsulated hydrophobic fluorochrome A (acceptor) and at least one encapsulated hydrophobic fluorochrome D (donor), wherein A is different from D and exposure to light radiation enables the emission from fluorochrome D to excite fluorochrome A, and a method for producing said latex and its use as a marker, particularly a biological marker, are also disclosed.
摘要:
The invention concerns a microfoamed fruit or vegetable puree containing native defatted soluble seric proteins and optionally a texturing agent, the overrun being not more than 50%, the average diameter of the bubbles being less than 200 μm and the microfoamed fruit or vegetable purée being stable for at least 28 days at a temperature ranging between 1 and 10° C. The invention also concerns a method for preparing same.
摘要:
The invention concerns a dry emulsion characterised in that it is obtained by drying a dispersion of at least a weakly soluble edible substance also called active substance (MA) in a continuous phase comprising: at least an emulsifier (E) containing at least a partially hydrolysed vegetable protein (protein lysate) whereof the degree of hydrolysis ranges between 0 (excluded) and less than 5%; and at least a water soluble or water dispersible interstitial filler (ARI) containing at least a partially hydrolysed vegetable protein (protein lysate) whereof the degree of hydrolysis ranges between 5 and 40%. The invention also concerns a method for preparing said emulsions, comprising the following steps: (i) a first step consists in preparing a dispersion in water or in an aqueous phase comprising at least a hydrophobic active substance (MA), at least an emulsifier (E), and at least a filler (ARI); (ii) the second step consists in drying said dispersion until a dry emulsion is formed. The invention further concerns the use of said dry emulsions for making food compositions.
摘要:
The invention relates to a latex microsphere consisting of polymers obtained by polymerization of ethylenically unsaturated monomers, having functional groups at the surface, and remarkable in that biotinyl residues are grafted onto at least part of the said groups, via a divalent chain. It also relates to the avidin- or streptavidin-biotin complex obtained with the aid of the said microsphere and to the use of the microsphere or of the complex as agent for diagnosis, for biological assay or for immunological assay.
