Substance Structure : Solid Brown Growing VHP Sugar

The bulk of the world’s VHP sugar is produced in Brazil from high sucrose sugar cane. In Brazil, most sugar cane is grown in the center south region adjacent to and in the Sao Paulo state. This region is well known for its large expanses of flat fields, fertile soils, and clement climate which are all ideal for growing sugar cane, which thrives in tropical or subtropical climates. Brazil is well known for spending much time and energy in the pursuit of better strains of sugar cane that grow faster and have higher sucrose contents than traditional forms of sugar cane which are still grown in many countries. This investment of time and money has paid off with high yield crops which are eminently suitable for the production of VHP sugar.

Sugar cane is generally planted in the summer months, left to grow between twelve and sixteen months, and then harvested in the cooler months. Typically the harvesting season in the Sao Paulo region of Brazil runs from May through to November.

VHP Sugar Production
There are several steps involved in the production of VHP sugar. First, the harvested cane must be shredded and cut in preparation for milling. The cane is then sent through rollers and subsequently through crushing devices that squeeze the juice out of the cane, separating it into two products, sugar juice, which will be refined into VHP sugar, and dry fibrous material known as bagasse, which will be recycled or used as fuel.

The sugar juice is then piped to a different part of the mill, where it is boiled in vacuum pans to remove excess water and concentrate the sugar content. Sugar dust crystals are then added to the juice to encourage the growth of sucrose crystals, which form around the dust crystals. When they are fully grown, both the liquid and the crystals are fed into a centrifugal chamber which spins the mixture at very high speeds, driving the liquid content away from the sugar crystals. What is left is high grade ‘A’ sugar and ‘A’ molasses (also referred to as first molasses). The high grade ‘A’ sugar is known as VHP.

The first molasses is then boiled again and subjected to a further crystal growth process. When crystals are grown, they are once more sent into the centrifugal chamber and spun to separate crystal from molasses. The results from this reprocessing are known as ‘B’ sugar, and second, or dark molasses. The second molasses does not contain nearly as much sucrose as the first molasses, and ‘B’ sugar is also of lower quality.

The process is then repeated again, this time with the products being final molasses, also known as ‘C’ molasses, or blackstrap molasses, and ‘C’ sugar. In some cases, the B and C sugars will then be remelted into a liquid solution and recrystallized to make high grade VHP sugar.

Production of VHP sugar requires quite a great deal of sugar cane, and it is estimated that for every hundred tons of sugar cane that is processed, only twelve tons of VHP sugar is produced.

VHP Sugar ICUMSA Ratings
Most VHP sugar falls somewhere between ICUMSA 600 and ICUMSA 1200 on the ICUMSA ratings scale. ICUMSA is an acronym, that stands for ‘International Commission For Uniform Methods Of Sugar Analysis’, which is the international body that regulates the way that sugar is analyzed.

The ICUMSA ratings system is based on a colormetric evaluation of sugar, and is carried out with an instrument called a colorimeter. This device is able to give a precise numerical reading which represents the coloration of the sugar sample which has been fed into it.

This is an effective means of testing the purity and quality of sugar because as sugar becomes more refined and pure, it loses the dark brown coloration associated with raw sugar which is relatively highly contaminated with biological agents and colorants, and becomes lighter and lighter. Highly refined sugar is a sparkling white color, whereas non VHP raw sugar can be ICUMSA 3000 or more. Because VHP sugar is so very high in sucrose and contains relatively few contaminants, it is a light brown color.

All sugar is tested according to how white it is, even brown sugar. Sugar is tested according to whiteness because the whiter sugar is, the more refining it has undergone, the less contaminants and chemicals are left in it, and subsequently the higher the quality it is. ICUMSA ratings are generally ‘reversed ratings’, meaning that the smaller the number is, the higher the quality of the sugar. This type of ICUMSA rating is known as the Brazilian SGS system, and it is the system under which we and most parts of the world trade sugar. In Europe this system is reversed, and ICUMSA 42 sugar actually refers to raw unrefined sugar. In order to simplify the sugar purchasing process, it is often simpler to ask for the Brazilian SGS rating of sugar.

But how does one know whether or not sugar is ICUMSA 150 or not? How can this be verified? The ICUMSA ratings test is carried out with a piece of equipment called a colorimeter, which is a device that gives a reading based on the wavelengths of light a substance absorbs.

ICUMSA 150 Sugar
ICUMSA 150 sugar is refined white sugar. Not quite as refined as ICUMSA 45 sugar, ICUMSA 150 sugar is still food grade and is often used by manufacturers making foodstuffs where the refining requirements for sugar are lower than those required for sugar sold direct to consumers. ICUMSA 150 sugar is in fact relatively highly refined sugar, especially when one considers that higher ICUMSA rated sugars are available, up to ICUMSA 4600 or more, but due to high levels of contamination and bacteria, these are not suitable for human consumption. ICUMSA ( International Commission For Uniform Methods Of Sugar Analysis) Ratings are ratings standardized by the aforementioned international body which reflect how refined sugar is, and thereby allow sugar to be traded across international borders with surety

Applications
It is a highly versatile product and may be employed in several applications, from domestic to industrial processes. Some of the several uses are: preparation of foods in general, soda, juice and sweetened beverage industries, brewery, baking, fondants, food industries, etc.

 About ICUMSA

ICUMSA (International Commission for Uniform Methods of Sugar Analysis) is a world-wide body which brings together the activities of the National Committees for Sugar Analysis in more than thirty member countries.

Work is carried out under various Subjects each headed by a Referee.

ICUMSA is the only international organisation concerned solely with analytical methods for the sugar industry. In addition to use by that industry, ICUMSA methods are recognised by authorities such as the Codex Alimentarius Commission, the OIML, the EU, and the US Food Chemicals Codex.

Methods are recommended for Tentative (T) approval by ICUMSA in the first instance. Upon meeting all the Commission’s requirements, methods are accorded Official (O) status. Methods which are demonstrably useful and have found an established application, or which do not lend themselves to collaborative testing, are given an Accepted (A) status. Details of how the status of Methods has been established may be obtained by reading the relevant Proceedings.

ICUMSA 45

Sugar trading features heavily in futures trading, and many crops are sold years before they are actually grown, sometimes up to three years before the sugar cane is even planted. Brazil refines relatively little of its sugar for export, so newcomers to the market will often find that much Brazilian ICUMSA 45 has already been sold quite some time before it was produced. For this reason, buyers looking to purchase large amounts of sugar, especially of ICUMSA 45, but also lower grade sugar often run into difficulties sourcing a reliable supplier.

According to the Brazilian SGS method of testing, ICUMSA 45 sugar is the highest quality sugar available on the market today. The quality of sugar is determined by a system devised by ICUMSA (International Commission For Uniform Methods Of Sugar Analysis), which is an international body that has sought to standardize the measurements which are used to describe sugar, so that no matter where the purchaser lives, or where the sugar source is located, an understanding of the type and quality of the sugar can be gained simply by quoting a rating, such as ICUMSA 45.

Sugar is tested according to a scale of whiteness. A simplistic way of looking at ICUMSA ratings is to say that the more white a sugar is, the more refined it is. ICUMSA 45 sugar is a sparkling white, highly refined sugar, suitable for human consumption and use in a wide range of food applications.

But how precisely is the whiteness of the sugar determined? In order for there to be an international standard, there needs to be a replicable scientific test to determine the ICUMSA rating of a sugar, and in order to achieve this level of precision and replicability, a colorimeter is used.

A colorimeter is a piece of equipment that determines which wavelengths of light are best absorbed by a substance. This is a useful piece of equipment, and a useful testing method because it is the ability of a substance to absorb various wavelengths of light that determines its color. Therefore, if a sugar is very white and very refined, it will absorb little light, something which can be quantified by the colorimeter.

To understand how this works in real world terms, think of how we humans perceive color. The human eye sees colors because certain objects absorb certain wavelengths of light, and reflect those which are not absorbed back to the eye. For example, a ball that appears blue to the human eye is simply made of a substance that absorbs all wavelengths of light apart from the blue ones, and reflects those back. The color, or rather the shade of white works similarly except for the fact that things which we perceive as being very white are actually absorbing almost no light, and instead are reflecting all the light back at the eye.

Sugar tested according to ICUMSA standards is usually tested with light wavelengths of 420 nm and 560 nm, and the standard colorimeter used to analyze sugar according to ICUMSA standards is a tristimulus colorimeter, an instrument which measures several readings along what is known as the visible spectrum (simply the spectrum of light that is visible to the human eye). The output reading is then based on how much light was absorbed by the sugar sample. A low reading, such as 45, indicates highly quality refined sugar which absorbs little light and appears very white to the human eye, whereas a high reading going into the 1000 + range indicates an unrefined raw sugar which absorbs much more light, and therefore appears brown and dark.
