Abstract: Disclosed is a method of producing a polyphenol-containing composition derived from grapes, the method including: preparing a liquid grape extract which includes polyphenols; contacting the liquid extract with a separation medium which fractionates the components of the extract; and recovering that fraction in which the polyphenols are present. Also disclosed is a method of enriching the composition with added flavonol.

Abstract: The carotenoids lutein and zeaxanthin are disclosed for pharmaceutical use in the treatment of advanced macular degeneration. High dosages are deployed to produce the high serum carotenoid levels needed to cause take-up by the macula.

Abstract: Disclosed are compositions which include creatine and Aloe Vera extract, for the purpose of increasing the creatine supply deposits of human beings, and to improve their intestinal health. The composition is presented as a drink, either constituted from a dry powder or in liquid form. Also disclosed is a method of increasing the stability of a drink or semi-liquid solid comprising creatine and Aloe Vera extract by storing the compositions below ambient temperature, preferably 0-8° C.

Abstract: A flavonol-containing dry composition derived from wine and useful as a food supplement is provided wherein at least 25% of the composition derived from wine includes polyphenols and at least 1.0% w/w of the composition is flavonol.

Abstract: Disclosed is a flavonol-containing dry composition suitable for human consumption, together with uses thereof.

Abstract: A flicker photometer comprises generating means (1, 8, 4) for generating two beams of light of different colors. Both beams are directed to a viewing means (190), and a subject can vary the intensity of light from one beam relative to the other. The color of the light seen by the subject is caused to alternate by a shutter (18) which is rotated about an axis by a motor, the shutter having a portion which extends non-perpendicularly relative to the axis to facilitate a compact construction of photometer. The performance of the photometer is improved by screens which scatter light before it reaches the subject. A first of the screens reflects light from one beam, whilst a second screen transmits light from the other.

Abstract: Disclosed is an acidic composition for human consumption, comprising creatine. In particular the composition is conveniently an isotonic drink for storage at 4.degree. C., or is a dry stable powder which may be stored at ambient temperature.

Abstract: A flicker photometer has beam generating means (1, 8 and 4) for generating two beams of light of different colors. Light from the beams is viewed at the viewing means, and the intensity of light of one beam relative to that of the other beam can be adjusted by adjustment means comprising an attenuating filter (20) which is movably mounted in the path of one beam. Movement of the filter relative to the beam alters the degree to which the beam is attenuated, and is achieved using an electric motor (22). The motor provides a relatively easy means of adjusting the filter position, and can be used to provide coarse and fine adjustments in response to suitable signals from an optical encoder. The motor also enables the filter, along with the beam generating means, to be mounted on a movable table for use in enabling the photometer to accommodate both short and long-sighted subjects.

Abstract: The invention provides a culinary seasoning composition. The composition comprises a saline component and a trace element component, the trace element component itself comprising at least one compound of a trace element selected from zinc, copper, manganese, chromium, selenium or molybdenum or a mixture of two or more such compounds. The composition is formulated such that a portion of from about 5 to about 15 grams of the composition contains at least a recommended daily dietary allowance of at least one of said trace elements.The composition is prepared by dissolving the trace element component in a small amount of water, blending the solution with part of the saline component or with at least part of any diluent or a mixture thereof, and thereafter blending with the saline component or the remainder thereof.

Abstract: The invention provides a process and confectionery product in the form of at least one bar. The product of the invention provides in said form a meal replacement or diet supplement and comprises a proteinaceous material and a carbohydrate material comprising indigestible carbohydrate. The proteinaceous material and the carbohydrate material are present in a relative weight ratio of from about 1:1 to about 1:10, and the indigestible carbohydrate is a carbohydrate having a molecular weight no higher than about 5,000.
