Sixty samples of sugar beets root were collected from different fields of Dakhlia, Alexandria, Kafer el sheakh and Sharkia (15 samples for each) and storage at mild conditions in Dakahlia Sugar Company for 29 days (from 1-29 June 2012). The levels of each of sugar, Na, K, ?N, beet quality and invert sugar were determined every two days of storage period for all samples. As general, there was an increase in each of K%, Na% & ?-N and a decrease in sucrose% at the storage period of 25-29 June 2012 of the beet root collected from the four regions. The beet quality (Qz %) was high at the first periods and decreased gradually, while, invert sugar (INV %) was low at first and increased gradually reached the maximum of decreasing at the end of experimental period.
During sugar manufacturing, the total determined sugar losses (sugar transferred into mud, pulp and molasses) were 2.74% in the first period (1-20/2/2011) of the campaign 2011, while, these total losses were ranged between 2.97 and 4.04% in all the other tested periods in this campaign. Undetermined sugar losses were high (2.2%) in the first period of campaign only and decreased into 0.626- 0.007% in all the other tested periods in the campaign 2011. While, the total determined sugar losses were ranged between 2.288 and 3.168% in the first 10 periods (from 20/2/2012 to 31/5/2012) of campaign 2012 and dramatically increased into 5.347 and 7.454% in the last two periods (from 11/6/2012 to 30/6/2012) of the same campaign. Undetermined sugar losses were 1.474% in the first period of campaign 2012 and decreased to less than 1% in the periods from 2 to 11 in the same campaign. At the last two periods of this campaign (11/6/2012 - 28/6/2012), an increase of undetermined sugar losses were again recorded. The dramatically increases in total determined and undetermined sugar losses in the last two periods (from 11/6/2012 to 28/6/2012) of the campaign 2012 may be due to the deterioration of beet juice resulting from the increase of microbial load. |
