Starch content — Sweet chestnut

Castanea sativa Mill.

Starch content is a determining indicator of the chemical composition of sweet chestnut fruits, ranging from 43 to 80 g per 100 g of dry matter. This trait directly affects the technological properties of the raw material, the texture of the finished product, and the suitability of varieties for th…

In the reference 4 varieties crop Sweet chestnut, where this is mentioned in the description.

The starch content in sweet chestnut fruits serves as the primary quality indicator considered by breeding companies when evaluating varieties. For the quantitative determination of the starch fraction, laboratory extraction methods from ground mass with subsequent hydrolysis and analysis are used, while the microstructure of starch granules is studied using light and scanning electron microscopy.

A high concentration of starch determines the nutritional value of the chestnut and dictates its culinary characteristics, such as the ability of the fruits to form a puree during heat treatment. The physicochemical properties of the starch granules and their quantity are key factors in selecting a variety for industrial processing into flour, which differs significantly in its qualities from cereal-based analogues.
