摘要:
One aspect of the present invention is concerned with a composition comprising caramelised carbohydrate, which composition, when dissolved in water at a dry solids content of 0.1 wt. %, exhibits: i. an absorption at 280 nm (A280) that exceeds 0.01, preferably exceeds 0.05, more preferably exceeds 0.1 and most preferably exceeds 0.3; and ii. an absorption ratio A280/560 of at least 200, preferably of at least 250. Other aspects of the invention relate to a method of manufacturing a beverage or foodstuff that is resistant to light induced flavour changes, said method comprising introducing into said beverage or foodstuff a composition as defined above; and to a process for the manufacture of said composition.
摘要:
One aspect of the present invention is concerned with a composition that can suitably be used as an additive in beverages and foodstuffs, which composition: i. contains at least 0.5%, preferably at least 1.0%, by weight of dry matter, of pyrazine derivatives according to formula (I): wherein R1-R4 independently represent hydrogen; a hydroxyhydrocarbyl residue; an ester of a hydroxyhydrocarbyl residue; or an ether of a hydroxyhydrocarbyl residue; and at least one R1-R4 is a hydroxyhydrocarbyl residue or an ester or an ether thereof, and ii. exhibits an absorption ratio A280/560 of at least 80, preferably of at least 250. The invention also relates to a method of manufacturing a beverage or a foodstuff that is resistant to light induced flavour changes, said method comprising introducing into said beverage or foodstuff the aforementioned light stabilising composition and to a process for the manufacture of such a light stabilising composition.

摘要:
This invention relates to an improved method of inhibiting corrosion and calcium sulfate and calcium carbonate scaling in thermal and membrane desalination processes. The method includes adding a composition having an acrylic acid 2-acrylamido-2-methylpropyl sulfonic acid copolymer, combined with a synergistically effective amount of oligomeric phosphinosuccinic acid to seawater or recirculation brine in a desalting process to produce water for drinking and industrial applications. The method also includes adding a composition including mono, bis, and oligomeric phosphinosuccinic acid adducts to the desalting process.
摘要:
This invention provides a method for detecting contamination of a boiler condensate and/or a boiler feedwater in industrial fermentation processes. The method includes measuring an oxidation-reduction potential at one or more locations in the fermentation process with one or more devices capable of measuring oxidation-reduction potential at operating temperature and pressure. If the measured oxidation-reduction potential is not within an optimum range, an alarm is triggered.
