BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...

background and objectives: recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...

in process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight .the volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. drought stress and dehydrated root reduce. the volume of the pulp extract of 23 ml. the objective of this experiment was to determine the proper...

Thick juice (also regarded as syrup) is an intermediate product of sugar processing. It is cheaper than processed sugar and is mainly composed of sucrose. Sucrose is a preferred carbon source of Corynebacterium glutamicum, a workhorse of biotechnology used for million-ton-scale amino acid production. Here, it is shown for C. glutamicum that sugar beet thick juice led to higher growth rates and ...

in order to determine the effects of water deficit at different growth stages of sugar beet and optimal usage of water on quality and quantity characters of sugar beet, a factorial experiment based on randomized complete block design was conducted with 13 treatments and four replications in 2000 and 2001 in agricultural research center of hamadan. for the first factor, irrigation withheld in th...

Tetragenococcus halophilus is known to flourish in extreme salt environments. Recently, this halophilic bacterium also appeared as the dominant microflora during storage of sugar thick juice, an intermediate product of beet sugar production. Although T. halophilus can cause degradation of thick juice, dominance of this bacterium does not always result in degradation. In this study T. halophilus...

in this paper, the effect of transmembarne pressure (tmp) at levels of 1, 1.75 & 2.5 bar, process temperature (t) at levels of 30 & 60oc and operation time (t) at levels of 15, 30, 45 & 60 minute on the permeate flux, sugar rejection, non-sugar rejection and fouling as membrane performance indexes investigated. membrane system used in this research was ceramic tubular module and it had effectiv...

Spent lime is a by-product of the sugar beet sugar purification process. It is generated by heating mined calcium carbon limestone to form calcium oxide and carbon dioxide. These two products are injected into the thick juice (from the sugar beet processing) and reforms calcium carbonate. When the calcium carbonate reforms it captures or adsorbs many of the impurities in the juice and precipita...

in 2006 the sugar beet crop production iniranwas largest ever.  in this year, 6,603,383 t with average sugar content of 16.84% delivered to the 32 sugar factories during five months of the campaign. from begining of the campaign until early–november there was balance between the amount of sugar beet delivered and that of processed by the sugar factories.  however, delivered beet to the factorie...

introduction: conventional technology of sugar production from sugar beet roots consists of the next subsequent steps: sugar beet slicing, thermal denaturation of the sliced beet roots followed by diffusion in hot water at 70–75 _c, purification of extracted juice by lime, concentration of purified juice and crystallization. the diffusion process is one of the most important steps that effect o...
