The deficiency in existing sugar cane crystallization automatic control system is difficult to measure some key parameters on line, such as mother liquor supersaturation, mother liquor purity, crystal content and crystal size distribution. Controlling brix with PID can only reflect the massecuite concentration of sugar cane crystallization process, but it is hard to guarantee the crystal qualit...

Last year, 'the Committee of Chemical Control (Proc. SA Sugar Tech. Assn., 1931, 10) recorded that they had discussed the methods in use for determining the density of molasses. and promised the publication of the results of a series of comparative tests using hydro. meter (1: 1 dilution), refractometer and pyknometer methods. These tests have now been carried out and are recorded in what follo...

Exhaustibility tests were carried out by concentrating molasses to 4 000 poise (determined a t 40°C), adding refined sugar, crystallising at 40°C for 48 hours and carrying out on the separated molasses a series of analyses which included sugars by gas-liquid chromatography (GLC) as well as Lane and Eynon methods. Regression analysis of the results showed that purity of the exhausted molasses wa...

Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

BACKGROUND L-tryptophan is an important ingredient in medicines, especially in neuromedicines such as antidepressants. Many commercial processes employ various microorganisms with high tryptophan synthase activity to produce L-tryptophan from indole and L-serine, but these processes are very costly due to the costs of precursors, especially L-serine. OBJECTIVES For this reason, we studied the...

THIS PAPER describes recent BSES initiatives to develop laboratory NIR systems for sugar industry applications, in particular, for the analysis of sugar, molasses and other factory products. For the analysis of sugar, previous BSES work to develop online NIR calibrations was available for adaptation to a laboratory or at-line format and was supplemented by a targeted program of analytical work ...

An effective extraction of the fiberized cane juice has been obtained from a prepared extraction column. Oligosaccharides co~nposed of glucose and fructose were found in both cane juice and in raw sugar. The oligosaccharides found In the juice and raw sugar were probably produced by enzymatic or bacterial reactions occurring in cane which had had a delay of 24 h or Inore between cutting and pro...
