Analysis of Starch
Amylose has an approximate degree of polymerisation (DP - number of monosaccharide units) of 2000 and the polysaccharide forms a helix with six glucose units in each turn. However, amylose is usually a minor component of most starches with amylopectin being the major constituent. Amylopectin again contains glucose units linked through alpha (1-4) bonds; however, there are also alpha (1-6) branches that occur every 24 to 30 glucose units in plants. Amylopectin also has a much higher DP than amylose (e.g. 200,000 residues in potatoes). It cannot coil into a long helix, however, because of the extensive branching, and the fact that the chains that do exist before branching are too short. This means that no compact intermolecular alignment, and hence no significant hydrogen bonding, can take place. This accounts for its extensive solubility, especially when compared with cellulose.
Compared to sucrose, the conversion of starch to ethanol is more complex since the polysaccharide is more resistant to hydrolysis, which means that catalysts are required. However, it is a lot easier to hydrolyse starch than cellulose due to the extensive hydrogen bonding of the latter and the complex lignocellulosic matrix it is contained within.
The main starch-producing feedstocks that are used for biofuel production are wheat (Triticum aestivum) and maize/corn (Zea mays). In a maize to ethanol dry-mill facility the maize is ground to a mash and heated in a cooker where the starch is enzymatically-hydrolysed using amylases and the liberated sugars are then fermented using yeasts. The main products are ethanol, and dried distillers grains which can be used in animal feed.
Maize wet-mills can produce, in addition to ethanol, an array of co-products including oils, proteins, fibre, and nutrients. That is possible because the germ, starch, gluten, and fibre are separated. Furthermore, after hydrolysis, the starch can be enzymatically converted to sweeteners (e.g. a high-fructose content syrup) as an alternative to fermentation to ethanol or other products.

The event takes place on May 3rd at Carrick-on-Shannon
We are pleased to announce that, on May 3rd, Celignis will be presenting and exhibiting at the National Biochar and Carbon Products Conference 2023, which is taking place in Carrick-on-Shannon in County Leitrm, Ireland.
This conference is being organised under the auspices of the Interreg Northwest Europe-funded THREE C Project, entitled 'Creating and sustaining Charcoal value chains to promote a Circular Carbon economy in NWE Europe'.
The conference will highlight both Irish stakeholders who are currently working in the biochar and carbon products sector, but also partners from the THREE C project (covering Netherlands, Luxembourg, Germany, Belgium, France and Wales, as well as Ireland) who have interesting stories and products to share.
