Starch analysis or starch grain analysis is a technique that is useful in archaeological research in determining plant taxa on a microscopic level. It can also be used in day-to-day life by specialists within the pharmaceutical and food industries in order to determine taxa origins and food quality. [ 1 ]
Phenol-Chloroform extraction is a liquid-liquid method used by biochemists to separate nucleic acids from proteins and lipids after cells have been lysed. [42] [citation needed] This method has fallen out of favor with scientists and microbiologists as there are easier methods available which require less hazardous chemicals.
The production of potato starch comprises the steps such as delivery and unloading potatoes, cleaning, rasping of tubers, potato juice separation, starch extraction, starch milk refination, dewatering of refined starch milk and starch drying. [citation needed] The potato starch production supply chain varies significantly by region. For example ...
Mueller Hinton agar is commonly used in the disk diffusion method, which is a simple and widely used method for testing the susceptibility of bacterial isolates to antibiotics. In this method, small disks impregnated with different antibiotics are placed on the surface of the agar, and the zone of inhibition around each disk is measured to ...
Partially hydrolysed potato starch makes for another non-toxic medium for protein electrophoresis. The gels are slightly more opaque than acrylamide or agarose. Non-denatured proteins can be separated according to charge and size. They are visualised using Napthal Black or Amido Black staining. Typical starch gel concentrations are 5% to 10%.

The pith of the sago palm, although highly toxic to animals in its raw form, is an important human food source in Melanesia and Micronesia by virtue of its starch content and its availability. There is a simple process of starch extraction from sago pith that leaches away a sufficient amount of the toxins and thus only the starch component is ...
