Improved enzymatic method for determination of lactate in alcoholic beverages.

Electrochemical-Enzymatic Determination of Glucose in Beverages

This laboratory seeks to quantitatively determine glucose concentration in common beverages. The method employed is enzyme catalyzed oxidation of glucose, quantified by chronoamperometry. With an inexpensive patterned electrode and low cost glucose oxidase enzyme, an electrochemical sensor is constructed to selectively measure glucose in complicated beverages which can present as analytically c...

An improved HPLC method for determination of colocynthin in colocynth

Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries.  It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...

Improved method for enzymatic determination of serum triglycerides.

I describe an enzymatic method for determing serum triglycerides (triacylglycerols). The triglycerides are hydrolyzed by a mixture of lipase and esterase. The glycerol released is determined by kinetic fixed-time analysis, with use of glycerol kinase, pyruvate kinase, and lactate dehydrogenase. Through addition of the competitive inhibitor ATP the Michaelis constant of pyruvate kinase is appare...

Gas-chromatographic Method for Volatile Congeners in Alcoholic Beverages Analysis

Alcoholic fermentation of fruits and cereals is the primary source of alcoholic beverages production. The main component in these drinks is ethanol; but there are also many secondary products like glycerin or acetaldehyde, and mixtures of other higher-order alcohols called “fusel”, also known as congeners. They are important for the characterization of alcoholic beverages and also for forensic ...
