Production of sugar from sugar cane and sugar beets requires the use of specialized chemical reagents in the process quality control laboratories of this important industry.
The International Commission For Uniform Methods of Sugar Analysis (ICUMSA) is a world-wide body which brings together the activities of the National Committees for Sugar Analysis in more than thirty member countries.
Analytical methods are accorded Official status by ICUMSA upon meeting the Commission's requirements. Many of the reagents found in ICUMSA procedures are manufactured by Baddley Chemicals. Purchasing information on these and other useful reagents in the industry is given below alphabetically.
Two of the most significant reagents manufactured by Baddley Chemicals for the sugar industry are the ABC Sugar Clarifier® and OCTAPOL®.These non-toxic and environmentally friendly chemicals have replaced the toxic Lead Subacetate in sugar laboratories in many countries.

II. Some General Guidelines
As with dry Lead Subacetate and the ABC Sugar Clarifier® ,the amount of Octapol TM required may vary depending on the nature of the sample. Depending on the appearance of the filtrate after treatment with the clarifier, the following general statements may be made:
IF THE FILTRATE IS CLEAR AND SLIGHTLY YELLOW
This is perfect!
IF THE FILTRATE IS CLEAR AND DARK
Increase the amount of clarifier
IF THE FILTRATE IS CLOUDY AND DARK Increase amount of clarifier and let sample stand longer after shaking before it is filtered.
IF THE FILTRATE IS CLOUDY AND SLIGHTLY YELLOW
Let sample stand longer after shaking before it is filtered.
IF THE FILTRATE IS CLEAR AND COLORLESS
Readable, but amount of clarifier may be decreased slightly.
IF THE FILTRATE IS CLOUDY AND COLORLESS Decrease amount of clarifier used.
III. Specific Procedures
Although the reagent is non-toxic and environmentally benign, it is a very fine powder and the usual precautions involved in handling such dusty materials should be taken. Consult the Material Safety Data Sheet for further information on proper handling proceures.
There is only a very small, negligible in practice, effect of the quantity of the reagent used upon the polarimeter readings obtained, and this very much lower than the effect of the quantity of lead subacetate.
All polarization readings should be done using the 200 mm tube since the reagent should produce clarified filtrate of enough color and turbidity for this.
The purity data, etc., calculated from the polarimeter readings obtained with use of this reagent should be done in the same way as those obtained using lead clarification.
Although weights of reagent are given in the procedures described below, they are only meant as a guide and the analyst should experiment and judge the quantity to be used by eye after weighing a few samples and gaining experience with the procedure. The quantity of reagent used should be that which gives the best filtration rate and clarity.

Pour about 100 ml of juice (cooled if necessary) into a 200 ml bottle fitted
with a stopper. Add about 5-6 grams of the reagent mixture to the juice, stopper tightly and shake vigorously for about twenty seconds. Pour the liquid into the filter paper. Discard or pour back the first 10 ml of filtrate if necessary.
2. Bagasse and Filter Cake Analysis
Prepare the bagasse extract in the conventional manner using the blender. Cool the solution, pour about 100 ml into a 200 ml bottle with a stopper. Add a few grams of clarifier, shake well and filter. (Large quantities of filter cake and water and mixing in a blender are preffered if possibl).
3. Syrup Analysis
Weigh 26 g of syrup into a 200 ml flask, add water to the mark and mix well. Pour about 100 ml into a 200 ml bottle with a stopper. Add about 5 g of reagent, shake well and filter.
4. Masscuite and Molasss Analysis
Prepare a 1:1 dilution of the material in the usual way. Weigh 26 g of the diluted material into a 200 ml flask, add water to the mark and mix well. Pour about 100 ml into a 200 ml bottle with a stopper. Add reagent, shake well and filter.
The quantity of reagent required depends upon the purity of the material being tested. Recommended quantities are:
A-Massecuite 5-6 g
A-Molasss and B-Massecuite 6-8 g
B-Molasses and C-Massecuite 8-10 g
Final Molasses 10-15 g
These quantities are only guidelines and the analysts involved should determine the optimum reagent quantity.
5. Raw Sugar Analysis
Octapol TM can be used to determine the polarization of raw sugar. Only a small amount of reagent is necessary and it is important to avoid excess reagent in order to achieve clear filtration rates. The recommended procedure is as follows:
Weigh 26.00 g of raw sugar and dissolve to a final volume of 100 ml in the usual way, making sure that all the sugar has disolved and that the solution is well mixed. Pour the solution into a small, clean and dry beaker, add about 1.5 g of clarifier and stir with a glass rod or spatula. Cover with a watch glass and allow to stand for a few minutes. Filter through paper and determine polarization in the usual way.
It is not necessary to weigh the clarifier each time but the analyst should weigh it a few times to become familiar with the quantity required. Cloudy filtrate and poor filtration usually mean that too much reagent has been used.
IV. Additional Comments
1. Experimental data on a large number of sugar samples indicate that the pol value by this procedure may average slightly lower than with Lead reagents, but the same as for the ABC Sugar Clarifier ®
2. This procedure is not the procedure included in raw sugar contracts.
3. In contrast to Lead reagents, Octapol TM does not precipitate much, if any, dextran and some high dextran raw sugars may show slightly higher polarization with Octapol TMthan with Lead reagents.

FREQUENTLY ASKED QUESTIONS ABOUT OCTAPOLTM
(LATEST REVISION:#4 dated 04/21/99)
OCTAPOLTM is a new lead-free chemical reagent developed at Baddley Chemicals Inc. for the clarification of sucrose-containing materials prior to polarimetric analysis. Field-testing was carried out in cane sugar factories in several countries (USA, Guatemala, Brazil, and Colombia) during 1998.
2. Why do we need a new clarifier? Lead Subacetate has worked fine in our sugar mill for over a hundred years.
Technically speaking, Lead Subacetate is an excellent clarifier for the Sugar Industry.
However, because of dangers it poses to (a) the health of the sugar technologists [who breathe the lead dust day after day and year after year] and (b) the environment, many sugar mills have made the decision to switch to a lead-free clarifier.
Lead is one of the most hazardous toxic metals because the poison is CUMULATIVE, and its toxic effects are many and severe.
Ingesting a small amount of a lead chemical the size of a person's fingernail can kill.(Since the poison is cumulative, breathing the dust of over a longer period of time can likewise cause death). Nausea and vomiting are followed by convulsions, coma, and finally death.
Even in small amounts, lead can cause big trouble. The body takes four to six weeks to rid soft tissues of the metal after it is ingested. It can take up to 30 years for lead to leave the bones.
Lead can damage the brain, liver, and kidneys. The symptoms of lead poisoning are many and varied. Lead interferes with the production of red blood cells, leading to anemia. Lead strips the myelin coating from nerves, causing weakness in the hands and feet. Even very tiny amounts can cause high blood pressure.
On a weight to weight comparison, OCTAPOLTM is approximately the same as that of Lead Subacetate, and less than that of "ABC Sugar Clarifier and Aluminum Chloride.
The cost of Lead Subacetate is, approximately, in the $6.00 to $12.00 per kilo range (depending on size, country of origin, etc). The cost of the "ABC Sugar Clarifier" is in the $12.00 to $18.00 per kilo range, and the cost of OCTAPOLTM is in the $6.00 to $12.00 per kilo range.
13. How can I purchase OCTAPOLTM?
In the USA, call Baddley Chemicals Inc. at (800-356-8696) or FAX (225-293-5635) Customer Service .
Outside the USA, in certain countries and areas, you may contact your Distributor. Or, contact directly the Export Department. at Baddley Chemicals Inc. by FAX (225-293-5635) or email (bilbad@baddley.com) and request a PRO-FORMA INVOICE.
It is packaged in a convenient laboratory size of 1.5 kilograms, which is enough clarifier for between 200 and 300 tests. (The quantity required for one test depends on the type test being carried out, juice quality, etc. However, one can assume that approximately 5 to 10 grams of OCTAPOL will be required per test.)

18. What is the shelf-life of OCTAPOLTM?
OCTAPOLTM is shipped in an unactivated state. In this unactivated state, it is stable indefinitely. To be used, however, it must be activated. After activation, the shelf-life is approximately three months.
19. What is the advantage of OCTAPOLTM over the procedure using Aluminum Chloride/Calcium Hydroxide/Filter Aid?
OCTAPOLTM is more convenient and less expensive. It is faster and requires the handling of only one substance instead of three. In addition, when Aluminum Chloride/Calcium Hydroxide/Filter Aid are pre-mixed, the shelf-life is only about one day whereas OCTAPOLTM can be used for several months.
20. Zinc Chloride is the basis of a clarification procedure. What is the advantage of OCTAPOLTM over Zinc Chloride?
It has been reported that color removal is more effective with OCTAPOLTM.
