About the ABC Sugar Clarifier ®(English Version)
The ABC Sugar Clarifier ®was developed at the Audubon
Sugar Institute, Louisiana Agricultural Experiment Station, LSU
Agricultural Center, Baton Rouge, LA, USA, as a replacement for
the toxic and environmentally harmful dry Lead Subacetate. It has
been found to be highly effective as a reagent for clarification
of sugar-bearing juices prior to pol measurements for various
process streams in sugarcane and sugarbeet factories, and in
sugar refineries.
The reagent is prepared for use by mixing the three dry, powdered
components A, B, and C. The components are non-toxic and
environmentally-safe compounds of calcium, silicon, and aluminum.
The great advantage of the ABC Sugar Clarifier®, in addition to
its non-toxic nature, is the simplicity of use. No special
training, no additional equipment, and no expensive
instrumentation are required when switching to the new clarifier.
Laboratory procedures are essentially identical to those used
with dry Lead Subacetate. And importantly, the ABC Sugar
Clarifier ®is priced competitively with Lead Subacetate, when
equal sizes are compared.
The ABC Sugar Clarifier® is now being used extensively in the
USA and Canada in both the Sugarcane and Sugarbeet industries.
Also, numerous mills in a number of countries in South and
Central America, and in the Caribbean have begun to switch from
Lead Subacetate to the ABC Sugar Clarifier.
In a sugarcane factory the reagent can be used for analysis of
Core Lab Juices, Mill Juices, Clarified Juices and Filtrates,
Bagasse, Filter Cake, Syrup, Massecuite, Molasses, and Raw Sugar.
This procedure is not yet included in Raw Sugar Contracts.
Laboratory directions for using the ABC Sugar Clarifier®,
written in both English and Spanish, are available by FAX
(504-293-5635) or EMAIL (bibad@premier.net)
In the sugarbeet factory the ABC Sugar Clarifier® can be used
for analysis of High Green, High Raw Pan, High Raw Massecuite,
Low Green, Low Raw Pan, and Molasses. Sugar refineries are using
the new clarifier for analysis of various Process Liquors and
Molasses.

Laboratory Procedures For Using The ABC Sugar Clarifier In Cane Factory Process Streams
I. Introduction
The ABC Sugar Clarifier is available in two formulations:
ABC Sugar Clarifier (Original Formulation). This reagent was developed in 1990 at the Audubon Sugar Institute, Louisiana Agricultural Center, as a replacement for the toxic and environmentally harmful dry Lead Subacetate. After several years of use it has been found to be a highly effective reagent for clarification of sugar-bearing juices prior to polarization measurements for various process streams in sugarcane and sugarbeet factories, and in sugar refineries.
ABC Sugar Clarifier (Dark Sample Formulation). Pressed juice for polarization measurements may vary considerably, depending on such parameters as maturity, freshness, mud or trash content, and origin. The unique multicomponent formulation of the ABC Suar Clarifier allows modification to be made to enhance specific functions of the various ingredients. Some sugarbearing juices are extremely dark and present difficulties in the clarification process. The Dark Sample Formulation has been designed to provide a powerful decolorizing effect.
II. Some General Guidelines
As with dry Lead Subacetate, the amount of ABC Sugar Clarifier required may vary depending on the nature of the sample. To determine the proper formulation and the proper qantities of clarifier to use, it is suggested that initially tests be carried out with the Original Formulation. Depending on the appearance of the filtrate after treatment with the clarifier, the following general statemnets may be made:
Filtrate Appearance |
Conclusion |
| Clear, Slightly Yellow | This is perfect!! |
| Clear, Dark | Increase amount of clarifier, or change to Dark Sample Formulation |
| Cloudy, Dark | Increase amount of clarifier and let sample stand longer after shaking before filtering, or try the Dark Sample Formulation |
| Cloudy, Slightly Yellow | Let sample stand longer after shaking before filtering |
| Clear, Colorless | Decrease amount of clarifier |
| Cloudy, Colorless | Decrease amount of clarifier |
III. Specific Procedures
The ABC Sugar Clarifier is available in the form of a kit in which the three components, A, B, and C are separately packaged in correct proportionate amounts in heat-sealed polyethylene bags.
The Small Size (100 Tests), Medium Size (500 Tests), and Large Size (1000 Tests) may be conveniently used by opening the kit and emptying the content of the three plastic bags into the mixing vessel. After replacing the lid, shake the mixture vigorously for at least five minutes to insure that a homogeneous mixture is obtained. Important: The three polyethylene bags containing Components A, B, and C should be emptied completely, mixed, and USED WITHIN APPROXIMATELY 10 DAYS. Care should be taken to minimize absorption of moisture by the components or the mixed reagent. Moisture absorption may substantially decrease the effectiveness of the ABC Clarifier, and/or decrease its effective lifetime.
For Best Results the components of the ABC Sugar Clarifier (Original Formulation) should be mixed and allowed to stand for 24 hours before being used. The activity of the ABC Sugar Clarifier (Dark Sample Formulation) is such that, after mixing, the mixture should be allowed to stand for about 72 hours before being used. If the freshly mixed reagent is used immediately, the juice may have a tendency to gel and filter slowly.
Although the reagent is non-toxic and environmentally benign, it is a very fine powder and the usual precautions involved in handling such materials should be taken. Consult the Material Safety Data Sheet for further information on proper handling procedures.
There is only a very small, negligible in practice, effect of the quanitity 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 nm 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 the use of this reagent should be done in the same way as those obtained using lead clarification.
Although weighs of reagent are given in the procedures described below, they are only meant as a guide and the analyst should judge the quantity to be used by eye after weighing a few samples and gaining experience with the procedure. The quanitity of reagent used should be that which gives the best filtration rate and clarity.
1. Core Lab Juices, Mill Juices, Clarified Juice, and Filtrate
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 well for about ten seconds. Pour the liquid into the filter paper. Discard or pour back the first 10ml of filtrate if necessary. Filter Aid should not be required.
2. Bagasse and Filter Cake Analysis
Prepare the begasse 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 reagent, shake well and filter. (Large quantities of filter cake and water and mixing in a blender are preferred if possible).
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 Molasses Analysis
Prepare a 1:1 dilution of the material in the usual way. Weigh 26 g of diluted material into a 200ml 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-Molasses and B-Massecuite 6-8 g
B-Molasses and C-Massecuite 8-10g
Final Molasses 10-15 g
These quantities are only guidelines and the analysis involved should determine the optimum reagent quantity.
5. Raw Sugar Analysis
The ABC Sugar Clarifier 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 26.00g of raw sugar and dissolve to a final volume of 100 ml in the usual way, making sure that all the sugar has dissolved and that the solution is well mixed. Pour the solution into a small, clean and dry beaker, add about 1.5 g of dry ABC Sugar 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 ABC reagent each time but the analyst should weigh it a few times to become familiar with the quantity required. Cloudy filtrate and poor filtration usually mea that too much reagent has been used.
IV. Additional Comments
1. Experimental data on a large number of sugar samples indicate that the value by this procedure averages about 0.2°S lower than with Lead reagents.
2. This procedure is not the procedure included in raw sugar contracts.
3. In Contrast to Lead reagents, the ABC Sugar Clarifier does not precipitate much, if any, dextran and some high dextran raw sugars have shown slightly higher polarization with ABC Sugar Clarifier than with Lead reagents.
Laboratory Procedures in Spanish
PROCEDIMIENTOS DE LABORATORIO PARA
EMPLEAR EL KIT CLARIFICADOR ABC EN INGENIOS AZUCAREROS
El primer dia que se va a emmplear el reactivo, abrir el kit y
vaciar las tres bolsas en el pomo plastico con tapa que se
suministra con el kit.Cierre la tapa y mezcle vigorosamente los
tres compuestos durante aproximademente conco minutos. Esto
asegurara que se consiga una mezcla homogenea. El reactivo esta
ahora listo para ser utilizado. El reactivo debe mantener sus
propiedades clarificadoras por aproximademente diez dias. Por lo
tanto, el analista debe escoger adecuadamente el tamano del kit a
emplearse, para asegurarse que todo el reactivo se emplee dentro
de los diez dias de haber sido preparado. Dejar reposar la mezcla
un dia, ante de usarla.
A pesar de que mas adelaante daremos los pesos del reactivo en
los procedimientos descritos segiudamente, estos son solamente
una guia y el analista debera juzgar la cantidad a ser empleada a
ojo, luego de pesar varias mas y de adquirir experiencia con el
procedimiento.
Si el reactivo ha sido recien mezclado y no ha reposado lo
suficiente, es sumamente activo por lo que el jugo tendra una
tendencia a gelificarse y filtrara muy lentamente. Si esto
ocurriese, repetir el ensayo empleando una menor caantidad de
reactvo.
A pesar de que el reactivo no es toxico y benigno al medio
ambiente, es un polvo sumamente fino y se deben tomar las
prescauciones usuales en el manipuleo de este tipo de materiales.
Existe un efecto sumamente pequeno, pue se puede ignorar para
fines practicos, por la ccantidad de reactivo empleado sobre las
lecturas del polarimetro obtenidas, y estee es mucho menor que el
efecto producido por la cantidad de subacetato de plomo.
Todas las lecturas de polarizacion deben ser efectuadas empleando
el tubo de 200 mm del polarimentro, debido a que el reactivo debe
producir un filtrado clarificado de suficiente bajo color y
turbidez para esto.
Los datos de pureza, etc., calculados de las lecturas del
polarimetro empleando este reactivo, deben ser efectuadas de la
misma manera que las que se utilizan cuando se emplea subacetato
de plomo.
1. Jugos de Nucleo, Jugo de Molino, Jugo Clarificado y Filtrado.
Eche aproximademente 100 ml de jugo (enfriado si fuese necesario)
en una botella de 200 ml con tapon. Anada entre 5 a 6 gramos de
la mezcla del reactivo al jugo, tape suavemente y agite
vigorosamente por aproximadamente diez segundos. Vacie el liquido
en el papel de filtro. Descarte o vuelva a vaaciar al pomo los
primeros 10 ml de la solucion filtrada si es necesario. No debe
ser necesario el uso de ayudas al filtrado.
2. Analisis de bagazo y cake de filtro.
Prepare el extracto de bagazo de la manera convencional empleando
la mezcladora. Enfrie la solucion, vacie alrededor de 100 ml en
una botellade 200 ml con tapon. Anada unos cuantos gramos de
reactivo, mezcle vigorosamente y filtre.
Pese 25 grams del cake de filtro y prepare una pasta y pongala en
una botella de 200 ml. Complete hasta la marca con agua, mezcle
vigorasamente y vacie 100 ml en una botella de 200 ml con tapon.
(Es preferible mezclar mayor cantidad de cake de filtros y agua,
empleando una mezcladora).
3. Analisis de Miel
Pese 26 grams de miel y echelo en un pomo de 200 ml, anada agua
hasta la marca y mezcle vigorosamente. Vacie aproximadamente 100
ml en un pomo de 100 ml con tapon, anada aproximadamente 5 grams
del reactivo, mezcle bein y filtre.
4. Analisis de Massecuite y Melaza
Prepare una solucion diluida 1:1 del material de la manera usual.
Pese 26 grams del material diluido en un pomo de 200 ml, anada
agua hasta la marca y mezcle bien. Eche aproximadamente 100 ml en
una botella de 200 ml con tapon. Anada reactivo, mezcle bien y
filtre.
La cantidad de reactivo que se requiere depende de la pureza de
los materiales que se esten analizando. Las cantidades
recomendadas son:
A-Massecuite: 5--6 grams
A-Melaza y B-Massecuite: 6--8 grams
B-Melaza y C-Massecuite: 8--10 grams
Melaza final: 10--15 grams
Estas cantidades son solo como guia y los analistas deben
determinar la cantidad optima en la cantidad de reactivo.
5. Analisis de Azucar Cruda
El Clarificador de Azucar ABC puede ser empleado para determinzar
la polarizacion en azucar cruda. Solo se requiere una pequena
acantidad del reactivo y es importante evitar usar demasiado
reactivo a fin de lograr un filtrado claro y una buena tasa de
filtracion. El procedimiento recomendado es el siguente:
Pese 26 grams de azucar cruda y disuelvala a un volumen final de
100 ml de la manera usual,asegurandose que toda el azucar se haya
disuelto y que la solucion este bien mezclada. Vacie la solucion
en un vaso de boca ancha (beaker) limmmmpio y seco, anada
alrededor de 1.5 grams del Clarificador ABC seco y mezcle con una
varilla de vidrio o espatula. Cubra con un vidrion de observacion
y dejelo reposar unos minutos. Filtre a traves de papel filtro y
determine la polarizacion de la manera usual.
No es necesario pesar el reactivo AABC cada vez, pero el analista
debe pesarlo unas cuantas veces hasta que se familiarize con su
uso para saber cuando reactivo emplear. Si el filtrado es turbio
(lechoso) o hay una mala filtraacion, usualmente esto significa
qu se ha emmmpleado demasiado reactivo ABC.
NOTAS:
1. Nuestros datos de laboratorio en una gran contidad de muestras
nos indican que los valores empleando este procedimiento
promedian alrededor de 0.1o S mas bajo que cuando se emmplean
reactivo de plomo.
2. Estre No ES el procedimiento que se incluye en los contratos
de azucar cruda con los canicultores.
3. A Diferencia de los reactivos de plomo, el Clarificador de
Azucar ABC no precipita mucho, casi nada de dextran y algunas
azucares de alto dextran han mostrado una polarizacion
ligeramente mas alta con el Clarificador de Azucar ABC que con
reactivos de plomo.
