Dry Matter Losses

Grains tend to lose weight during deterioration dne to respiration and/or the matter consnmed by insects, molds, and rodents. Deteriorated kernels are also more prone to break dnring handling, transportation, and distribution. Dry matter losses due to

In postharvest studies of tobacco, initial dry weight is often the basis for calculation and evaluation. However, there is usually dry matter loss from biochemical change during the observation period. It is therefore advisable to determine corrected weights based on the concentrations of inert components such as calcium (Frankenburg 1950). The method for calcium by atomic absorption as carried out in the Agronomy Department of the University of Kentucky follows ...

Biomass yield variables—those that affect the mass per acre delivered to the biorefinery—are particularly important since they reside at the front end of the feedstock supply chain and thus have broad impacts that extend through the entire supply chain. In fact, biomass yield affects many of the other variable categories identified in the analysis, including machinery performance and system variables (harvest window and transportation distance). Accordingly, uncertainties of biomass yield variables—particularly collection efficiency and storage dry matter losses—are the focus of the discussion that follows.

When ultrafiltering twin screw extracts, the 6 kDa membrane from Poly mem was the only one to reach a CR of 2. At this point, the flux was 15L/h.nr with a 44% dry matter loss and a 34% demineralisation rate. The salt concentration of the final powder remained the same because it depends on the salt solubility in alcohol.

During malting, the barley loses between 5% and 10% of its dry matter. The moisture, malting temperature, and time usually increase dry matter losses. The main chemical changes that barley suffers during malting are reduction in the assayable...
