Abstract: Detection arrangement and method for detecting presence of a residue in a sample by determining color values of the sample, associated with the L*a*b color model, where a value of a composite parameter Z is calculated as follows: Z=wL+waa+wbb where wL, wa, and wb are weighting factors having a value depending on said residue and said sample, and a determination is made whether or not said sample comprises more or less than a predetermined amount of said residue in dependence on said value of said composite parameter Z. In a preferred embodiment, the arrangement is used to detect antibiotic residues, e.g. penicillin-G, in food products, e.g. milk, or body fluids, e.g. blood, urine.

Abstract: Method and arrangement to locate an object with a predetermined number of marks, the arrangement comprising a light source, a sensor and a processor, by means of the following steps:—illuminating the object with the light source;—receiving an image of the object and generate image pixel data including image pixel locations and image pixel intensities for each image pixel location with said sensor;—receiving the image pixel data and storing them in a memory;—comparing said image pixel intensities with a predetermined threshold;—determining object position based on said comparing;—using a digital match mask that corresponds with said object with said marks;—finding a best match between said digital match mask and said object on said object position;—determining mark positions within said object position from said best match.

Abstract: The present invention describes a method of isolating or extracting fluid from a tissue comprising treating the tissue with microwaves and collecting the resulting tissue fluid.

Abstract: The present invention described a device which comprises: a first container having at least one hole or outlet means present in the bottom and/or sides of the first container; a second container; and a compressor or means to apply pressure where the device is constructed in such a way that it is able to squeeze or compress a sample present in the first container, and hence releases forces or separates fluid from the sample where the first container is constructed in such a way that some or all of the fluid separated from the sample will pass through the hole or outlet into the second container. The device allows the preparation of fluid samples from tissue in a reliable, reproducible inexpensive manner.

Abstract: A substrate for mushroom cultivation comprises a polyene fungicide, in particular, natamycin. Mushrooms cultivated in such substrates can be harvested earlier than mushrooms cultivated in substrates which do not include polyene fungicides. Alternatively, mushrooms grown in a substrate comprising a polyene fungicide achieve a greater size than mushrooms grown for the same amount of time in a substrate which does not include a polyene fungicide.

Abstract: The present invention provides a method of preparing an improved antifungal composition containing an antifungal compound of the polyene type such as natamycin wherein the antifungal compound is incorporated into the composition in a form which shows an enhanced activity, e.g. in the form of a solution and/or being in a modified polymorphic form.

Abstract: A complex comprising natamycin complexed to one or more proteins. Processes for producing the same. Compositions containing the same. Use of the complexes as a preventative antifungi treatment for natural products. A method for preventing the infection of a natural product by fungi, the method comprising treating the natural product with the complex.

Abstract: A complex containing natamycin complexed to one or more proteins. Processes for producing the same. Compositions containing the same. Use of the complexes as a preventative antimycobacterial treatment for natural products. A method for preventing the infection of a natural product by mycobacteria the method containing treating the natural with the complex.

Abstract: An aqueous composition is disclosed which comprises 0.1 to 20 g/l of polyene fungicide, 0.5 to 50 g/l of a suitable thickener and optionally 20 to 250 g/l of salt.

Abstract: Novel compositions that comprise solvates, salts, or other modified crystalline forms of polyene-type antifungal compounds are provided. Representative of such compositions are formulations that comprise the novel cystalline substances .delta.-natamycin and .gamma.-natamycin. Additionally, there are provided methods of preparing or storing such compositions, and also methods of use whereby an enhanced rate of release of antifungal compound, in a pharmaceutical or food products application is achieved.

Abstract: The present invention discloses a method for the preservation of beverages comprising the use of a killer toxin. Specifically, zymocin is used in carbonated drinks. The zymocin is shown to be active against a wide range of different yeast strains. The invention further discloses a DNA fragment encoding zymocin. The DNA sequence is also disclosed.

Abstract: Concentrated suspensions of polyene fungicides such as natamycin are disclosed which exhibit good chemical, microbial and physical stability and which are thus particularly suitable as stock suspensions for the preparation of immersion liquids and coating emulsions for treatment of food, feed and agricultural products. Such suspensions have a pH in the range 3 to 4.8 and include a thickening agent.
