Influence of grinding on the preservation of starch

2019-11-16  In addition, our results indicate different grinding techniques also result in different levels of damage to starch grains and hence different degrees of preservation. Among the different grinding techniques, dry‐grinding causes significant morphological changes to starch grains and consequently affects starch grain detection, especially in the case of rice.

Influence of grinding on the preservation of starch

2019-11-16  To understand this apparent scarcity of starch grains from rice, dry- and wet-grinding experiments with stone tools were carried out on four types of cereals: rice (Oryza sativa L.), foxtail millet (Setaria italica), Job's tears (Coix lacryma-jobi L.) and barley (Hordeum vulgare L.). The results reveal that dry-grinding produces significant damage to starches to the point where they may be undetected in archaeological samples, while wet-grinding

Grinding of leaves for extraction of nucleic acids

One of the most traditional and common methods for harvesting nucleic acids from plants involves grinding leaves in liquid nitrogen with a mortar and pestle. Either the mortar and pestle can be pre-chilled and the grinding performed dry on frozen leaves, or the leaves can be submersed in liquid nitrogen for the grinding. Cryogenic grinding is a very effective technique for taking hard substances, like plant and

This grinding method could have been inherited from the earlier hunter-gatherers, but could also result from a broad-spectrum subsistence strategy adopted at Jiahu.
