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 ]
Examined under a microscope using a mixture of equal volumes of glycerol and distilled water, potato starch presents transparent, colorless granules, either irregularly shaped, ovoid or pear-shaped, usually 30 μm to 100 μm in size but occasionally exceeding 100 μm, or rounded, 10 μm to 35 μm in size.
It usually contains between 2% and 5% of an anti-caking agent—such as corn starch, potato starch or tricalcium phosphate [1] [2] —to absorb moisture, prevent clumping, and improve flow. Although most often produced in a factory, a proxy for powdered sugar can be made by processing ordinary granulated sugar in a coffee grinder , or by ...
The traditional method is to take glutinous rice mixed with malt, and let the natural enzymatic process take place, converting the starch to syrup [1] which consists mainly of maltose. [2] The second and more common method is acid hydrolysis of potato starch or sweet potato starch by adding acid, such as hydrochloric , sulfuric or nitric acids ...
Statoliths, a specialized starch-accumulating amyloplast, are denser than cytoplasm, and are able to settle to the bottom of the gravity-sensing cell, called a statocyte. [5] This settling is a vital mechanism in plant's perception of gravity, triggering the asymmetrical distribution of auxin that causes the curvature and growth of stems ...

The starch industry extracts and refines starches from crops by wet grinding, washing, sieving and drying. Today, the main commercial refined starches are cornstarch, tapioca, arrowroot, [38] and wheat, rice, and potato starches. To a lesser extent, sources of refined starch are sweet potato, sago and mung bean.
Malt extract or malt syrup – a sweet, sticky, brown liquid made from barley ; Maltose [1] – a disaccharide formed from two units of glucose joined with an α(1→4) bond, formed from a condensation reaction; Maltodextrin, maltol [1] – a white powder or concentrated liquid made from corn starch, potato starch, or rice starch. Although it ...
