Topinambų gumbų rauginimo proceso tyrimai

Abstract

Researchers searching for ways to reduce production losses suffered for storage. One of the possible way to silage artichoke - fermentation. Plant raw material, which consist of saccharose and which is used for biogas protuction - is silaged in large underground silos tanks. Natural weight loss turned Jerusalem artichokes fretwork is very dependent on the ambient temperature and surface formed crust characteristics. Holding the artichoke weight 0 and 25 °C temperatures, when the surface was covered with a moisture - proof plastic revealed that weight loss was kept at a temperature of 0 °C the weight over 69 days was only 1,32 %, while the 25 °C - 6,9 %. A chemical test found that the average nitrogen content changed from 0,8 % to 1,7 % dm, phosporus increased from 0,4 to 0,6 % d.m., organic carbon content increased from 51,4 to 56,3 % d.m. The potassium content remained the same on average and inulin levels decreased to 2,2 % dm.
