Abstract: An apparatus for filtering and sterilizing water utilizing a turbidity and microorganism sensing system. The apparatus includes a UV light source that emits UV and visible light and light sensors. The light sensors include visible light detectors and light pipes that are impregnated with a fluorescent dye to covert UV light to visible light. The turbidity level is assessed by the detection of visible light passing through the water flow path while the microorganism levels are assessed by the detection of visible light that has been converted from UV light passing through the water flow path. The light sensors are in communication with a microprocessor which evaluates the intensity of the visible light and UV light. The microprocessor compares these intensities to a UV and visible light intensity standard to determine whether the water has been properly filtered and irradiated.

Abstract: A method of increasing the concentration of caffeic acid derivatives, such as cichoric acid, and the concentration of alkylamides, such as tetraene alkylamides, in Echinacea plant postharvest; and a composition, having increased amounts of these phytochemicals per gram of plant material. The method includes the following steps: (1) harvesting a plant having caffeic acid derivatives and alkylamides; (2) separating the plant into fragments; and (3) storing the separated fragments in refrigerated conditions at a controlled relative humidity which prevents wilting and microbial decay. The raw plant material obtained from this process can be used alone or in combination with other nutrients in a medicine or dietary supplement.
