Overproduction of sugar causes a reduction in the acreage under sugar beet. That is why new non-food technologies for exploitation of agricultural products are sought. Utilization of beet for liquid fuel production could be one of them. The aim of experiments with sugar beet raw juice fermentation was to verify the possibility to return a part of distiller's slops back to the fermentation process and thereby to obtain stillage with higher content of dry solids. This would bring about energy savings during slops thickening and drying. Tests with recycling of different portions of stillage (20, 25 and 30%) back to the fermentation stage were carried out. No significant increase in dry solids content in mash was found and therefore no energy savings during thickening can be expected. The only savings can be made in water consumption that is replaced by slops.
Vaňha J., Hinková A., Sluková M., Kvasnička F. (2009): Detection of plant raw materials in meat products by HPLC. Czech J. Food Sci., 27: 234-239.The Czech legislation (Decrees No. 326/2001, 202/2003 and 651/2004 of the law No. 110/1997 as amended) regulates the requirements for the selected meat products with regard to the contents of individual ingredients. However, the methods of the determination of compliance with these regulations are not closely specified. The study presented here deals with the development and verification of analytical methods suitable for the detection of the material of plant origin. Due to the high variability in the contents in meat products of these ingredients, various markers were observed (isoflavones, phytic acid, galactooligosaccharides). For the purpose of detection, substances commonly used in food processing industries were taken into account such as soy flour, wheat flour, soy isolate, HAM 60 preparation. The values gained by measuring the given markers were subsequently converted to reflect the amount of the plant based substance added. Out of 18 products commonly available in shops, only 7 filfilled the legal criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
