Article Synopsis
- Ceres has notable amounts of aliphatic organics, with concentrations ranging from 5 to over 30 weight % in certain areas of its surface.
- The origins and longevity of these organics are questioned, especially since radiation levels in Ceres' orbit should typically break them down, complicating their detection.
- Laboratory experiments suggest that organic materials degrade quickly under radiation, indicating that buried organics may have been exposed in the recent past, and estimates show the initial abundance of aliphatics could be 2 to 30 times higher than what is currently observed.
Background: In Romania, the Alveograph is the most used device to evaluate the rheological properties of wheat flour dough, but lately the Mixolab device has begun to play an important role in the breadmaking industry. These two instruments are based on different principles but there are some correlations that can be found between the parameters determined by the Mixolab and the rheological properties of wheat dough measured with the Alveograph.
Results: Statistical analysis on 80 wheat flour samples using the backward stepwise multiple regression method showed that Mixolab values using the ‘Chopin S’ protocol (40 samples) and ‘Chopin + ’ protocol (40 samples) can be used to elaborate predictive models for estimating the value of the rheological properties of wheat dough: baking strength (W), dough tenacity (P) and extensibility (L).
