Peroxide Value Test Principle, Procedure, Result

Unsaturated fish oils are especially vulnerable to oxidation, resulting in peroxides when stored in cold or freezing conditions for storage. Peroxides are precursors to breakdown products that can cause rancid taste in fat. Peroxide levels are an indicator of oxidation in the initial stages of lipid degradation. The index is less reliable in the latter

Phenol-Sulfuric Acid Method for Total Carbohydrates

The phenol-sulfuric acid technique is a fast and easy method for determining the amount of carbohydrates present in an experiment sample. It can detect virtually all kinds of carbohydrates including di-, mono-the -, and even oligo and polysaccharides. Although the method is able to detect nearly every type of carbohydrates, their absorptivity for the various

Nelson Somogyi Method for Determination of reducing sugars

Nelson-Somogyi method can be used to quantify the reduction of sugar using arsenolmolibdat and copper reagents. The principle behind the Nelson Somogyi method is the quantity of deposro oxide deposits which react with arsenomolibdate, which reduces to molybdine blue. The blue hue is determined by as absorbance. The keto and aldehyde free groups are regularly

Rapid Furfural Test for Glucose and Fructose

The rapid furfural test is a type of chemical test which is used to determine the difference between fructose and glucose. The test for rapid furfural is like Molisch’s test however it utilizes concentrated hydrochloric acid instead of concentrated sulfuric acid, and the solution is then boiled. A dilute solution of sugar is added in

Many bacteria produce a group of enzymes known as beta-lactamases that are mediated through genes in plasmids or the chromosomes. Beta-lactamase can be a constant process or it may be triggered through contact with antimicrobials. Beta-lactamases hydrolyze (and consequently inhibit) the beta-lactam ring of many Cephalosporins as well as penicillins. Beta-Lactamase Test is a rapid test to determine the...
