The longer the active oxygen formation lag time or the lower the active oxygen formation activity, the greater the oxygen resistance of the fermented alcoholic beverage, thus making it possible to evaluate that fermented alcoholic beverage as having good flavor stability.

  • Patent number: 5716850
    Abstract: A method of determining one or both of the colour and bitterness of beer by illuminating the beer with light of a pre-determined wavelength, typically 400.+-.30 nm, to cause iso-.alpha.-acids in the beer to fluoresce. The fluorescence is detected over a range of wavelengths, typically 420 to 673 nm, using a fluorescence spectrophotometer. One or both of the colour and bitterness of the beer is determined by comparing an output signal from the fluorescence spectrophotometer to output signals stored for beers of known colour and bitterness.

  • Patent number: 5658798
    Abstract: The invention is a method of monitoring for the presence of certain constituents of food processing streams by measurement of fluorescence. The constituent monitored can be a fluorescing impurity of a food product, or the food product itself if such naturally fluoresces. Moreover, losses of the constituent to be monitored may be determined by concurrent measurement of fluorescence of a fluorescent material added to the food process stream. The method is applicable to the following food processing streams among others: meat, vegetable oil, sugar beet, sugar cane, grain, poultry, fruit and soybean processing streams. Upon determination of a variation of the fluorescing constituent to be measured, the food process can be adjusted accordingly.

  • Patent number: 5441872
    Abstract: A new enzymatic rate method is disclosed for the analysis of Vitamin C using ascorbate oxidase. Total Vitamin C can be measured in a single analysis, in a procedure amenable to automation. Any dehydroascorbic acid (DHAA) in the sample is reduced to ascorbic acid. Then a coupling agent such as o-phenylenediamine (OPDA) is added to the sample, and any nonspecific reactions with, or spectrometric interferences from, other components of the sample are measured, to be blanked out from the final measurement. Then ascorbate oxidase is added, oxidizing ascorbic acid to DHAA; the DHAA then reacts with the OPDA already present from the prior step, and the quinoxaline derivative product may be measured spectrometrically, e.g., by absorbance at 350 nm.

  • Patent number: 5200909
    Abstract: A method and apparatus for classifying wine by chemically analyzing a wine sample to determine content values indicative of amounts of constituents in the wine sample, evaluating potential interaction among constituents in the wine sample, converting the content value of each of the constituents to a scaled value adjusted for interaction with the other constituents, the scale to which each of the content values is converted being equal in size, and displaying the scale values so that palatability factors for the sampled wine can be determined by viewing the display.

  • Patent number: 5179005
    Abstract: A method for determining the presence of an analyte in a fluid is described along with various components of an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface of an inert porous matrix impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analyzed is applied to another surface and migrates through the matrix to the surface being read. Reflectance measurements are made at two separate wavelengths in order to eliminate interferences, and a timing circuit is triggered by an initial decrease in reflectance by the wetting of the surface whose reflectance is being measured by the fluid which passes through the inert matrix. Repeatability is insured by a normalization technique performed on the light source before each reading, and an alignment method operated on the reagent strip prior to emplacement on the apparatus.

  • Patent number: 4987083
    Abstract: An improved process and apparatus for making carbonated beverages in which water is mixed with a syrup and the resulting mixture is carbonated and filled into containers in a filling line, the improvement is the following:a sample of beverage is continuously removed before the beverage is filled into containers and then the sample is passed into a cell of a photometric analyzer and the concentration of syrup is photometrically measured which generates a signal; the signal is fed to a process controller which compares the signal to a signal stored in the controller having been generated by the photometric analyzer of an analysis of a sample of a standard beverage containing a predetermined level of syrup concentration and precisely determines the deviation of syrup concentration of the sample from the standard; a trim amount of water is added to the beverage to control the syrup concentration of the beverage to the concentration level of the standard; and the beverage is passed through a static-in-line mixer t
